Umhlahlandlela Womthengi Wezishaja ze-DC ezingu-150kW: Amamodeli Okwakhiwa Kwemodeli kanye Nemali Engenayo

Umhlahlandlela Womthengi Ophelele Wezobuchwepheshe Weziteshi Zokushaja Okusheshayo ze-150kW DC: Ukuzulazula Ezakhiweni Zamandla Eziguquguqukayo, Ukuhlanganiswa Kwegridi, Ukuphathwa Kokushisa, Izinhlelo Zokuvikela Ezinezingqimba Eziningi, Ukusebenzisana Kwe-OCPP, kanye Namamodeli Emali Engenayo Engakhula Yengqalasizinda Ye-EV Evikela Ikusasa

Isahluko 1: Isingeniso: Ukwanda Kokushaja Okusheshayo kwe-150kW DC Emhlabeni We-EV Womhlaba Wonke

Ukuguquka komhlaba wonke ukuya ekuhambeni kukagesi akuseyona into engaphandle kodwa kuyinsika ebalulekile yenqubomgomo yesimo sezulu yamazwe ngamazwe kanye nesu lezimboni. Njengoba ukuvinjelwa kwenjini yokushisa yangaphakathi (ICE) kukhula ezimakethe ezinkulu kanye nokwamukelwa kwabathengi kwezimoto zikagesi (ama-EV) kushesha, isidingo sengqalasizinda yokushaja eqinile, ethembekile, neshesha kakhulu sesifinyelele izinga eliphezulu. Ngaphakathi kobubanzi be-Electric Vehicle Supply Equipment (EVSE), ishaja esheshayo engu-150kW DC ivele “njengendawo emnandi” ebalulekile kubaqhubi bezentengiselwano, abaphathi bezimoto, kanye nabahlinzeki bezinsiza zomphakathi.

Ngokungafani namashaja e-AC anamandla aphansi afanele ukusetshenziswa endlini ebusuku, noma amashaja anamandla aphezulu angu-350kW+ okwamanje agcinelwe izimoto zikanokusho eziphezulu kanye namaloli amade, isiteshi esingu-150kW sinikeza isiphakamiso esilinganiselayo. Sinikeza izikhathi zokushintsha ezisheshayo kakhulu kunezinjini ezingu-50kW—ngokuvamile sigcwalisa u-80% webhethri le-EV lesimanje ngaphansi kwemizuzu engama-30—ngenkathi sigcina indawo elawulekayo kanye nesidingo segridi. Lokhu kusenza sibe yisinqumo esifanele seziteshi zesevisi zomgwaqo omkhulu, izindawo zokuthengisa, kanye nezindawo zasemadolobheni “zokugcwalisa ngokushesha”.

Kodwa-ke, ukukhetha ishaja efanele engu-150kW akuyona nje indaba yokukhetha uhlobo kukhathalogi. Kuhilela ukuqonda okujulile ngama-elekthronikhi anamandla, ubuchwepheshe bokupholisa, izinqubo zesofthiwe, kanye nokumodela kwezomnotho. Iyunithi ekhethwe kabi ingaholela ezindlekweni eziphezulu zokulungisa, isikhathi sokungasebenzi njalo, kanye nokuphelelwa yisikhathi ngokushesha njengoba ubuchwepheshe bebhethri buthuthuka. Lo mhlahlandlela usebenza njengolwazi olujulile lobuchwepheshe ezweni lokushaja okusheshayo okungu-150kW DC, okunikeza abathengi ulwazi oludingekayo ukuze babhekane nobunzima bokukhetha, ukufaka, kanye nokusebenza kwesikhathi eside.

Sizohlola ukuthi kungani i-modularity iyisisekelo somklamo weshaja wanamuhla, ukuthi ukuphathwa kokushisa okuthuthukisiwe kuvikela kanjani isikhathi sokuphila kwemishini, nokuthi ukuhlanganiswa ne-Open Charge Point Protocol (OCPP) kuqinisekisa kanjani ukuthi utshalomali lwakho luhlala luguquguquka futhi lusebenzisana. Ngaphezu kwalokho, sizohlaziya amamodeli emali engenayo enza iziteshi ezingu-150kW zibe yicala lebhizinisi elisebenzayo, sibheke ngale kokuthengisa okulula kwe-kilowatt-hora kuya ezinsizakalweni ezengeziwe kanye nokusekelwa kwegridi.

Isahluko 2: Ukukhetha Kobuchwepheshe: Ukuchaza Umkhawulo Wezinjini Ongu-150kW Wokusetshenziswa Kwezentengiselwano Nomphakathi

Uma kuhlolwa ishaja esheshayo engu-150kW DC, into yokuqala okufanele icatshangelwe ngobuchwepheshe umthamo wangempela wokulethwa esibonakalayo semoto. Akuwona wonke amashaja “angu-150kW” adalwe ngokulinganayo. Amandla alinganisiwe avame ukuba yisilinganiso esiphezulu esifinyelelwa kuphela ngaphansi kwe-voltage ethile kanye nezimo zamanje. Kumthengi, ukuqonda ububanzi bamandla kagesi—ngokuvamile kusuka ku-200V kuya ku-1000V—kubalulekile. Ama-EV esimanje, njengalawo akhiwe phezu kwezakhiwo ezingu-800V (isb., iPorsche Taycan, iHyundai IONIQ 5, iKia EV6), adinga amashaja angagcina amandla kagesi aphezulu ukuze afinyelele isivinini sawo esiphezulu sokushaja. Ishaja ekhawulelwe ku-500V izobhekana nobunzima bokuletha amandla kagesi angu-150kW kulezi zimoto ezintsha, okuvimbela ukusebenza kahle.

Esinye isici esibalulekile sokukhetha ikhono "lokushaja ngesikhathi esisodwa". Iziteshi eziningi ezingu-150kW zifakwe izixhumi ezimbili (CCS1, CCS2, noma CHAdeMO). Isiteshi sekhwalithi ephezulu sizoba nokwabelana kwamandla okushintshashintshayo. Isibonelo, uma izimoto ezimbili zixhunyiwe, isiteshi kufanele sikwazi ukwabela i-75kW ngayinye, noma sibeke imoto phambili ngokuhlakanipha ngesimo sokushaja esiphansi. Ukuqonda ubunye balokhu kwabiwa kwamandla—kungakhathaliseki ukuthi kwenzeka ngokukhushulwa kwe-10kW noma ukuhlukaniswa okungaguquki kwe-50/50—kuyisici esibalulekile sobuchwepheshe.

Isilinganiso sonyawo olubonakalayo kanye nesilinganiso sokuvalelwa nakho kudlala indima ebalulekile. Ekufakweni kwasemadolobheni lapho isikhala siphezulu khona, iyunithi encane, yonke-in-one ivame ukukhethwa. Kodwa-ke, ezindaweni zomgwaqo omkhulu, uhlelo lokwakha oluhlukanisiwe (lapho ukuguqulwa kwamandla kwenzeka khona ekhabhinethini elikude futhi umsebenzisi exhumana ne-dispenser encane) lungase lufaneleke kakhulu. Abathengi kumele futhi baqinisekise izilinganiso zokuvikela ukungena (IP) kanye nokuvikela umthelela (IK). Ekusetshenzisweni komphakathi kwangaphandle, isilinganiso se-IP54 noma se-IP55 esihlanganiswe nesilinganiso se-IK10 sezindlu kanye nesikrini ngokuvamile kubhekwa njengendinganiso yemboni yokuqina ngokumelene nesimo sezulu kanye nokucekelwa phansi.

Okokugcina, i-interface yomsebenzisi (i-UI) kanye nokuhlanganiswa kokukhokha akukwazi ukunakwa. Ishaja engu-150kW iyingqalasizinda ebheke umphakathi. Ukukhetha kobuchwepheshe kumele kufake isikrini sokuthinta esikhanya kakhulu, esifundeka elangeni, ukwesekwa kwezilimi eziningi, kanye netheminali yokukhokha eqinile esekela i-RFID, amakhadi esikweletu/edebithi, kanye nezikhwama zeselula. Ezindaweni eziningi, imithetho "yokufinyelela okuvulekile" manje iyalela ukuthi amashaja kumele amukele amakhadi esikweletu ngaphandle kokudinga uhlelo lokusebenza oluthile noma ubulungu, okwenza ukukhetha ihadiwe yokukhokha ehlanganisiwe kube yisidingo somthetho.

Isahluko 3: Amandla Okuguquguquka: Ukwakhiwa Kwezakhiwo, Ukulinganisa Okuhambisanayo, kanye Nokuphindaphindwa Komsebenzi

Ezinsukwini zokuqala zokushaja okusheshayo kwe-DC, amayunithi amaningi akhiwa kusetshenziswa ukwakheka "kwe-monolithic". Uma ingxenye eyodwa yangaphakathi yehluleka, yonke ishaja yayingasebenzi. Namuhla, imboni isishintshele ekuklanyweni kwe-modular parallel, okungenzeka ukuthi kuyintuthuko ebaluleke kakhulu kwezobuchwepheshe kumashaja angu-150kW. Kulo mklamo, umkhiqizo ongu-150kW ukhiqizwa yinqwaba yamamojula wamandla amancane, ashintshwayo ashisayo—ngokuvamile angu-20kW, 30kW, noma 40kW ngalinye.

Izinzuzo ze-modularity ziphindwe kathathu: ukuthembeka, ukuseviswa, kanye nokukhula. Ngokombono wokuthembeka, uma ishaja engu-150kW yakhiwe ngamamojula amahlanu angu-30kW futhi imojula eyodwa yehluleka, isiteshi asibi mnyama. Esikhundleni salokho, singena "kwimodi eyonakele," siqhubeka nokunikeza umsebenzisi amandla angu-120kW. Lokhu kuqinisekisa ukuthi umshayeli akakaze aphuthelwe, okubalulekile ekugcineni ukwaneliseka kwamakhasimende okuphezulu kanye nedumela lesayithi.

Ukuseviswa nakho kuthuthukisiwe kakhulu. Esikhundleni sokudinga unjiniyela ochwepheshile kakhulu ukuthi axilonge futhi alungise imigudu yangaphakathi eyinkimbinkimbi endaweni, uchwepheshe angavele abone imojuli enephutha bese eyishintsha ngemizuzu embalwa. Lokhu kunciphisa i-Mean Time to Repair (MTTR) futhi kunciphisa umthwalo wezokuthutha wokufaka izingxenye ezinkulu nezisindayo. Kwabasebenzi abakhulu, lokhu kusho ukuthi izindleko zokusebenza ziphansi kakhulu (OPEX).

Okokugcina, i-modularity inikeza indlela yokuvikela ikusasa. Umthengi angase aqale ngokucushwa okungu-150kW kodwa afake ikhabhinethi ekwazi ukuthwala amamojula afinyelela ku-200kW noma angu-300kW. Njengoba isidingo sikhula futhi umthamo wegridi uvuma, umqhubi angamane afake amamojula engeziwe ukuze andise umthamo wendawo ngaphandle kokudinga ukushintsha isiteshi sonke noma ukumba imisele emisha. Le modeli "yokukhokha njengoba ukhula" ikhanga kakhulu abatshalizimali abangaqiniseki ngesilinganiso esisheshayo sokwamukelwa kwe-EV endaweni yabo ethile.

Isahluko 4: Ukusebenzisana Kwemojuli Yamandla: Ukuthuthukisa Ukusebenza Kahle kanye Nama-Algorithm Okulinganisela Umthwalo

Ubuhlakani beshaja esheshayo engu-150kW DC abugcini nje kuphela ezingxenyeni zayo zamandla aluhlaza, kodwa nasesofthiweni eyinkimbinkimbi ehlela ukusebenzisana phakathi kwamamojula wamandla ayo ayisisekelo. Kuhlelo lwe-modular, isilawuli esiphakathi sisebenza "njengobuchopho," silawula indlela amandla adonswa ngayo kumojula ngamunye ukuze kwandiswe ukusebenza kahle kanye nokuphila isikhathi eside. Lokhu kufezwa ngama-algorithms athuthukisiwe okulinganisela umthwalo aqapha impilo yangempela, izinga lokushisa, kanye nomlando wokusetshenziswa kwawo wonke amamojula ngamunye esitaki.

Ukuthuthukisa ukusebenza kahle kuyisici esibalulekile ekusebenzeni kahle kwesiteshi sokushaja. Amamojula amaningi kagesi anejika lokusebenza kahle elifinyelela phezulu emthwalweni othile—ngokuvamile phakathi kuka-50% no-80% womthamo wawo olinganiselwe. Uma ishaja engu-150kW iletha ama-kW angu-30 kuphela emotweni enebhethri elicishe ligcwele, ukusebenzisa wonke amamojula ngomthwalo ongu-20% ngeke kusebenze kahle ngenxa yokulahlekelwa kokushintsha okungaguquki kanye nokudonsa amandla okusiza. Isilawuli esihlakaniphile sizobeka amamojula amane endaweni yawo yokulala bese siqhuba imojula eyodwa engu-30kW endaweni yayo yokusebenza kahle ephezulu. Lokhu kusebenza "kwemodi yokulala" kungasindisa izinkulungwane zama-kilowatt-hours esikhathini sokuphila kweshaja, kuthinte ngqo umugqa ophansi womqhubi.

Ukulinganisela umthwalo kudlulela nasekuphathweni kokushisa kwamamojula. Ngesikhathi seseshini zamandla aphezulu, amamojula akhiqiza ukushisa okukhulu. I-algorithm eyinkimbinkimbi izojikeleza umthwalo phakathi kwamamojula ukuqinisekisa ukuthi ayikho iyunithi eyodwa ehlala ishisa kunezinye. Ngokusabalalisa "ukucindezeleka kokushisa" ngokulinganayo, uhlelo luvimbela ukuguga kwendawo futhi lwandise i-Mean Time Between Failures (MTBF) kuyo yonke i-power stack. Ngaphezu kwalokho, la ma-algorithm angathola izimpawu zokuqala zokuwohloka kwamamojula—njengezivunguvungu zamandla ezingavamile noma ukushisa okweqile komthwalo othile—futhi awenze abekwe uphawu lokulungisa ngaphambi kokuba kwenzeke ukwehluleka.

Kumasayithi okuhambisa ama-multi-dispenser, ukusebenzisana kuba yinkimbinkimbi nakakhulu. Ikhabhinethi yamandla ephakathi nendawo ekhonza izisekelo eziningi kumele yabelane ngamandla izinsiza zayo zemojuli ngokusekelwe kuma-curve ahlukene e-state-of-charge (SoC) ezimoto ezixhunyiwe. Uma imoto eyodwa isesigabeni sayo "sokushaja okukhulu" futhi ingamukela u-150kW, kanti enye isesigabeni "sokunciphisa" yamukela u-20kW kuphela, uhlelo kumele lushintshe amamojuli kalula kusuka komunye umkhiqizo kuya komunye. Lokhu kudinga izinqubo zokuxhumana ezisheshayo (ngokuvamile ezisekelwe kubhasi le-CAN noma i-Ethernet yezimboni) ngaphakathi kweshaja ukuqinisekisa ukuthi ukushintsha kwamandla kwenzeka ngama-millisecond ngaphandle kokuphazamisa iseshini yokushaja noma ukuqala ukuvalwa kokuphepha eceleni kwemoto.

Isahluko 5: Ukuphathwa Kokushisa Okuthuthukisiwe: Ukupholisa Umoya Okumanzi vs. Okuphoqelelwe Kwama-Rectifier Anamandla Aphezulu

Njengoba amashaja asheshayo e-DC efinyelela ebangeni elingu-150kW nangale kwalokho, ukuphathwa kokushisa kuba yinselele enkulu yobunjiniyela. Ukuguqula i-AC enamandla aphezulu kusuka kugridi ibe yi-DC yebhethri akuphumelelanga ngokuphelele; ukulahleka kwamandla okucishe kube ngu-4% kuya ku-7% kubonakala njengokushisa. Ohlelweni lwe-150kW, lokhu kusho ukuphatha ukushisa okufika ku-10kW—okulingana nezifudumezi eziningana ezinkulu ezisebenza ngaphakathi kwebhokisi lensimbi elivalekile. Indlela lokhu kushisa okuphathwa ngayo inquma ngqo ukuthembeka kweshaja, izinga lomsindo, kanye nezidingo zokulungisa.

Ukupholisa umoya okuphoqelelwe kuyindlela yendabuko nevame kakhulu yamayunithi angu-150kW. Isebenzisa amafeni ezimboni anesivinini esikhulu ukudonsa umoya ozungezile ngamamojula kagesi nakuma-heat sink. Nakuba kungabizi futhi kulula ukuwunakekela, ukupholisa umoya kunezinkinga eziningana. Okokuqala, kungenisa ukungcola kwemvelo—uthuli, umswakama, nomoya kasawoti—kuma-elekthronikhi angaphakathi abucayi, okudinga izihlungi zekhwalithi ephezulu nezishintsha njalo. Okwesibili, lapho amandla ephezulu kakhulu, amafeni angaba nomsindo omkhulu, okungaba yinkinga ezindaweni zokuhlala noma ezindaweni zokuthengisa ezisezingeni eliphezulu. Ukuze kuncishiswe lokhu, abanye abakhiqizi basebenzisa amafeni “aguquguqukayo e-speed drive” akhuphuka kuphela uma kudingeka, kodwa umkhawulo oyisisekelo usalokhu ukhona.

Ukupholisa uketshezi “kuyindinganiso yegolide” yama-elekthronikhi anamandla aphezulu, yize kuvame ukutholakala kumashaja anamandla angu-350kW+ ashesha kakhulu. Kodwa-ke, eminye imiklamo ye-premium engu-150kW isiqala ukusebenzisa amamojula apholiswe uketshezi noma ubuchwepheshe be-cold-plate. Kulezi zinhlelo, i-coolant (ngokuvamile ingxube yamanzi-glycol) ijikeleziswa ngamamojula kagesi, ithwala ukushisa iye ku-radiator ekude. Lokhu kuvumela indawo evalwe ngokuphelele, ivikele ama-elekthronikhi ezintweni zezulu futhi inciphise kakhulu umsindo. Kubathengi abasezimweni zezulu ezimbi kakhulu—kungaba ngamahlane ashisayo kakhulu noma ezindaweni ezisogwini ezinomoya onosawoti—izindleko eziphezulu zangaphambilini zesistimu yomoya opholile uketshezi noma ovaliwe zivame ukufaneleka ngokugcinwa okuncishisiwe kanye nokuphila isikhathi eside kwemishini.

Okunye okubalulekile okufanele kucatshangelwe ekushiseni okungu-150kW ikhebula lokushaja uqobo. Izintambo ezijwayelekile ezingapholi ngokuvamile zikhawulelwe kuma-Amps angu-200 ngenxa yokwanda kokushisa kuma-conductor ethusi. Ukuze ihambise i-150kW emotweni engu-400V, uhlelo ludinga ukusunduza ama-Amps angu-375. Lokhu kudinga ikhebula elijiyile kakhulu, elisindayo, nelinzima ukubamba, noma ukusetshenziswa kwekhebula elipholisiwe ngoketshezi. Ikhebula elipholisiweyo lisebenzisa uketshezi olujikelezayo ukugcina isibambo kanye nentambo kupholile, okuvumela ukwakheka okuncane, okunobungani kakhulu okungaphatha i-400A noma i-500A. Lapho ukhetha ishaja engu-150kW, abathengi kumele bahlole ukuthi iyunithi ifaka izintambo ezipholisiwe noma ukuthi isebenzisa izindlela "zokukhulisa" ezivumela ugesi ophezulu isikhathi esifushane kulandelwe ukugoba kokushisa.

Isahluko 6: Ukuxhumeka Kwegridi Nekhwalithi Yamandla: Ama-Harmonics, Ama-Transformers, kanye Nokugcinwa Kwamandla Kwendawo

Ukufakwa kweshaja esheshayo engu-150kW DC kuyiphrojekthi yobunjiniyela bezakhiwo njengoba kunjalo nangogesi. Iyunithi eyodwa engu-150kW idonsa amandla amaningi kugridi yokusabalalisa yendawo—ngokuvamile engaphezu kwesakhiwo esincane sehhovisi noma izindlu eziyishumi nambili zihlangene. Lokhu kudinga ukubambisana ngokucophelela nenkampani yezinsiza yendawo ukuqinisekisa ukuthi igridi ingakwazi ukusingatha imithwalo yezinyathelo ezisheshayo nezinkulu ezihambisana nokushaja okusheshayo.

Ikhwalithi yamandla iyinkinga enkulu kwezobuchwepheshe kumasevisi. Amashaja asheshayo ayimithwalo engaqondile esebenzisa ukushintshashintsha kwemvamisa ephezulu, okungangenisa "ama-harmonics" kugridi. Lawa ma-harmonics angabangela ukushisa ngokweqile kuma-transformers okusetshenziswa kanye nokuphazamiseka kweminye imishini ebucayi kusekethe efanayo. Amashaja asezingeni eliphezulu angu-150kW kumele abe ne-Active Power Factor Correction (PFC) kanye nokuhlunga okuyinkimbinkimbi ukuze kugcinwe i-Total Harmonic Distortion (THD) ngaphansi kuka-5%, okuhlangabezana nezindinganiso ezifana ne-IEEE 519. Abathengi kufanele bafune izitifiketi eziqinisekisa ukuthi ishaja ngeke "ingcolise" ukunikezwa kwamandla endawo, njengoba ezinye izinsiza zingase zenqabe ukuxhumana namayunithi angenawo ukuhlunga okufanele.

Ingqalasizinda ebonakalayo ivame ukudinga i-transformer ezinikele ukuze yehlise amandla aphakathi (isb., 11kV noma 33kV) aye ku-480V noma 400V AC edingwa yi-charger. Le transformer kumele ibe nosayizi hhayi nje kuphela we-150kW, kodwa nomthwalo ongaba khona kanye nokwandiswa kwesikhathi esizayo. Ngaphezu kwalokho, ibanga phakathi kwe-transformer ne-charger libalulekile; ukuhamba isikhathi eside kwekhebula le-voltage ephansi kungabangela ukwehla okukhulu kwamandla kagesi kanye nokulahlekelwa amandla, kunciphise amandla asebenzayo alethwa emotweni futhi kwandise ibhili kagesi lomqhubi.

Ezindaweni ezinegridi ezibuthakathaka noma “izindleko zokufunwa” eziphezulu (izijeziso zokusetshenziswa kwamandla aphezulu), isitoreji samandla sendawo siba yisisombululo esidumile. Ngokuhlanganisa ishaja engu-150kW ne-Battery Energy Storage System (BESS), opharetha bangakwazi “ukushaja” igridi. I-BESS ishaja kancane kusuka kugridi ngesikhathi esingekho isikhathi esiphezulu bese ikhipha ngokushesha ukusekela isidingo esingu-150kW lapho imoto ingena. Leli cebo “lokushefa okuphezulu” linganciphisa kakhulu izindleko zokusebenza futhi livumele ukushaja okusheshayo ezindaweni lapho ukuthuthukiswa kwegridi eqondile kungabiza kakhulu. Ukuhlanganisa lokhu ekukhetheni kobuchwepheshe kudinga ishaja enokwakheka kwe-DC-link okungamukela kalula okokufaka okuvela kugridi kanye nebhethri elingashintshi.

Isahluko 7: Ukuphepha Kuqala: Izindlela Zokuvikela Ihadiwe Nesofthiwe Ezinezingqimba Eziningi

Ukuphepha ekushajeni kwe-DC enamandla aphezulu kubaluleke kakhulu, njengoba ishaja engu-150kW isebenza ngama-voltage kanye nama-current angaba yingozi uma ingaphathwa kahle. Isiteshi se-150kW esisezingeni lobuchwepheshe sihlanganisa izendlalelo eziningi zokuvikela, kusukela ezixhumini ezibonakalayo kuya kusofthiwe yokuphatha esekelwe efwini. Lezi zindlela zenzelwe ukuvikela umsebenzisi, imoto, igridi, kanye nemishini yokushaja ngokwayo emaphutheni.

Isendlalelo sokuqala ukuvikelwa kwehadiwe ebonakalayo. Lokhu kufaka phakathi Amadivayisi Amanje Asele (ama-RCD) ohlobo B, angathola kokubili ukuvuza kwe-AC kanye ne-DC. Uma kwenzeka iphutha lomhlabathi, la madivayisi angakhubeka ngama-millisecond, ahlukanise ishaja ekuhlinzekweni kwamandla. Ngaphezu kwalokho, ishaja kumele ibe namadivayisi okuvikela ukukhuphuka (ama-SPD) ukuze ivikele ekushayweni kombani noma ama-grid transients. Ngaphakathi kwekhabhinethi, imojuli ngayinye yamandla kufanele ibe ne-fuse noma i-circuit breaker yayo ukuvimbela ukwehluleka kwendawo ukuthi kungangeni engozini enkulu yomlilo. Ikhebula lokushaja ngokwalo liqukethe izinzwa zokushisa ekhanda lesixhumi; uma amaphini eshisa kakhulu ngenxa yokuxhumeka okubi noma amazinga okushisa aphezulu, uhlelo luzonciphisa ngokuzenzakalelayo amandla noma luqede iseshini.

Isendlalelo sesibili ukuphepha okusekelwe ekuxhumaneni. Ukushaja kwe-DC yesimanje kuncike kumaphrothokholi e-ISO 15118 noma e-DIN 70121 okuxhawulana phakathi kweshaja nemoto. Ngaphambi kokuba kunikezwe i-watt eyodwa yamandla, lezi zinhlelo ezimbili zenza ukuzihlola. Imoto ixhumana nempilo yebhethri layo, i-voltage ephezulu evumelekile, kanye nemikhawulo yamandla aphezulu. Ishaja iqinisekisa isimo sayo sangaphakathi kanye nokumelana nokushisa. Kuphela ngemva kokuba izinhlangothi zombili ziqinisekisile isimo "esiphephile ukuqhubeka" lapho i-contactor ivala khona. Kuyo yonke iseshini yokushaja, lokhu kushaya kwenhliziyo kokuxhumana kuyagcinwa; uma uxhumano lulahleka ngisho nama-millisecond ambalwa, iseshini iyanqanyulwa ngokushesha ngenxa yokuphepha.

Isendlalelo sesithathu ukuqapha ukufakelwa. Amashaja asheshayo e-DC asebenza ngendlela "yegridi ye-IT" (i-terra ehlukanisiwe), okusho ukuthi imigqa ye-DC emihle neyimbi ayixhunyiwe phansi. Idivayisi Yokuqapha Ukufakelwa (IMD) ilinganisa njalo ukumelana phakathi kwebhasi le-DC kanye ne-chassis. Uma ukungena komswakama noma ukuguguleka kwekhebula kubangela ukuthi ukufakelwa kunciphe ngaphansi komkhawulo othile (ngokuvamile okulinganiswa ngama-kilo-ohms), i-IMD ibangela ukuvala ngokushesha. Lokhu kubalulekile ekuvimbeleni izingozi "zokuthinta i-voltage" lapho umsebenzisi angathola khona ukushaqeka okuvela ekhasejini lensimbi leshaja.

Okokugcina, ukuvikelwa okuchazwe yisofthiwe kunikeza isivikelo esingafuneki. Isilawuli esiphakathi siqapha yonke idatha yesenzwa—izinga lokushisa, i-voltage, i-current, kanye nesivinini sefeni—ngokumelene nesethi yezimvilophu zokuphepha ezichazwe kusengaphambili. Uma noma iyiphi ipharamitha idlula ngaphandle kwendawo ephephile, isofthiwe ingaqala ukuvala okulawulwayo. Isibonelo, uma i-voltage yegridi yehla kakhulu (i-brownout), isofthiwe izomisa ngomusa iseshini ukuvimbela umonakalo ezigabeni zokufaka zamamojula wamandla. Izinhlelo ezithuthukisiwe nazo zinophawu “lokuthola i-arc flash,” olusebenzisa izinzwa zokukhanya ukuthola ama-arcs kagesi angaphakathi futhi luphazamise i-breaker eyinhloko ngaphambi kokuba umlilo uqale.

Isahluko 8: I-Ecosystem Yesofthiwe: I-OCPP 1.6J/2.0.1 Ukuhlanganiswa, Ukukhokhisa, kanye Nokuphathwa Okude

Ishaja esheshayo engu-150kW DC akuyona into esetshenziswayo eyedwa; iyidivayisi exhunywe kunethiwekhi okumele ihlanganiswe nesistimu yesofthiwe eyinkimbinkimbi. Izinga lomkhakha lalokhu kuxhumana yi-Open Charge Point Protocol (OCPP). Uma ukhetha ishaja, ukuqinisekisa ukuhambisana ngokugcwele ne-OCPP 1.6J (JSON) kuyimfuneko encane kakhulu, kuyilapho ukusekelwa kwezinga elisha le-OCPP 2.0.1 kunconywa kakhulu ukuze kuvikelwe esikhathini esizayo.

I-OCPP ivumela ishaja ("indawo yokushaja") ukuthi ixhumane neseva ephakathi ("Uhlelo Lokuphatha Isiteshi Sokushaja" noma i-CSMS). Lokhu kuhlanganiswa kwenza izici ezibalulekile njengokuqapha okude, izibuyekezo ze-firmware, kanye nokukhokhisa. Kumthengi, ukuhlanganiswa kwe-OCPP kusho "akukho ukukhiya komthengisi." Uma ungajabuli ngomhlinzeki wakho wesofthiwe, ungashintshela kwenye ngaphandle kwesidingo sokushintsha ihadiwe ebonakalayo. Lokhu kuguquguquka kubalulekile ekuqineni kokusebenza kwesikhathi eside. Ishaja "evulekile" ngempela izoba nokuqaliswa kwayo kwe-OCPP okuqinisekiswe yi-Open Charge Alliance (OCA), okuqinisekisa ukuthi ingakhuluma kalula nanoma iyiphi i-back-end ehambisanayo.

Ukukhokhisa kanye nokwenza imali kuphathwa ngaleli layer lesofthiwe. Ishaja ithumela idatha elinganisiwe ku-CSMS, ezobe isicubungula izinkokhelo ngokusekelwe kumandla asetshenzisiwe (kWh), isikhathi esichithwe (imizuzu), noma inhlanganisela yakho kokubili. Ezimakethe eziningi, amanani aguqukayo aba isu elibalulekile—ukushaja kakhulu ngesikhathi samahora okufunwa okuphezulu futhi kunikeza izaphulelo lapho ukukhiqizwa kwamandla avuselelekayo kuphezulu. Amashaja athuthukisiwe angu-150kW nawo asekela i-“Plug & Charge” (ISO 15118-2), lapho imoto iziveza khona kushaja ngokuzenzakalelayo, isusa isidingo samakhadi e-RFID noma izinhlelo zokusebenza zeselula. Lokhu kunikeza ulwazi olungenamthungo “olufana ne-Tesla” kumsebenzisi futhi kwandisa ukugeleza kwesiteshi.

Ukuphathwa nokuxilonga kude yilapho uhlelo lwesofthiwe lunikeza khona inani elikhulu. Isiteshi esingu-150kW siyimpahla enenani eliphezulu, futhi isikhathi sokungasebenzi sisho ngqo imali engenayo elahlekile. I-CSMS eqinile inganikeza izexwayiso zesikhathi sangempela nganoma yimaphi amaphutha, okuvumela opharetha ukuthi balungise izinkinga—njengokulenga kwesofthiwe noma i-breaker ekhubekile—kude ngaphandle kokuthumela uchwepheshe kusayithi. Ngaphezu kwalokho, izibuyekezo ze-firmware ezikude ziqinisekisa ukuthi ishaja ingahlala ihambisana namamodeli amasha e-EV njengoba ekhishwa. Njengoba amakhemikhali ebhethri kanye nama-curve okushaja eshintsha, isofthiwe yeshaja idinga ukubuyekezwa ukuze ithuthukise ukusebenza nokuphepha.

Isahluko 9: Ukuhlaziywa Kwezomnotho: I-Capex, i-Opex, kanye ne-150kW Revenue Model (ROI)

Ukutshala imali kushaja esheshayo engu-150kW DC kudinga ukuqonda okucacile ngesimo sezezimali. Izindleko Zobunikazi Eziphelele (i-TCO) zihlukaniswe nge-Capital Expenditure (i-CAPEX) kanye ne-Operational Expenditure (i-OPEX), ngayinye okumele ihlelwe ngokucophelela ukuqinisekisa imbuyiselo enhle ekutshalweni kwezimali (i-ROI).

I-CAPEX ifaka intengo yokuthenga yeshaja ngokwayo, engaba phakathi kuka-$30,000 kuya ku-$60,000 kuye ngezici kanye nekhwalithi yokwakha. Kodwa-ke, izindleko zehadiwe zivame ukuba ngu-40% kuya ku-50% kuphela wezindleko zokufaka. Imisebenzi yokwakha—ukufaka imisele, ama-concrete pad, kanye nama-bollard okuvikela—ingaba yinto ebalulekile, ikakhulukazi ezindaweni zasemadolobheni. Ukuthuthukiswa kukagesi, okuhlanganisa i-transformer entsha kanye ne-switchgear enamandla amakhulu, kungangeza amashumi ezinkulungwane zamaRandi ebhili. Imali yokuvumela kanye nokuxhumeka enkampanini yezinsizakalo kumele futhi ibhekwe. Kubathengi abaningi, izibonelelo zikahulumeni kanye nezikhuthazo zentela kubalulekile ekukhokheni lezi zindleko zokuqala, ngokuvamile ezihlanganisa u-50% kuya ku-80% we-CAPEX ezifundeni ezinemigomo yokufakelwa kukagesi enamandla.

I-OPEX yizindleko eziqhubekayo zokugcina isiteshi sisebenza. Ingxenye enkulu kakhulu ngokuvamile yizindleko zikagesi, ezingahlanganisi nje amandla asetshenziswayo kodwa futhi "nezindleko zesidingo." Lezi yizimali zanyanga zonke ezisekelwe ekudonsweni kwamandla okuphezulu kakhulu (ku-kW) okuqoshwe endaweni. Iseshini eyodwa engu-150kW ingabangela inkokhelo yesidingo ephezulu esusa inzuzo evela kumaseshini amaningi amancane. Ukuphatha lokhu kudinga isofthiwe yokushaja ehlakaniphile noma isitoreji sebhethri sendawo njengoba kuxoxwe ngakho eSahlukweni 6. Ezinye izinto ze-OPEX zifaka phakathi ukubhaliswa kwanyanga zonke kwe-CSMS, ukuxhumana kweselula kweshaja, kanye nokuvakasha kokulungisa kwaminyaka yonke. Umthetho omuhle wesithupha ukubhajetha u-3% kuya ku-5% wezindleko zehadiwe zokulungisa nokulungisa kwaminyaka yonke.

Imodeli yemali engenayo yesiteshi esingu-150kW ishintsha ngale kokuthengiswa kwamandla okulula. Ngenkathi "umkhawulo nge-kWh" kuyiyona eyinhloko, abaqhubi abaphumelelayo bahlukanisa imithombo yabo yemali engenayo. Abanye banikeza amanani "esivinini esiphezulu", lapho amakhasimende akhokha khona izinga eliphezulu lokufinyelela ishaja engu-150kW uma kuqhathaniswa namayunithi ahamba kancane. Abanye basebenzisa isiteshi sokushaja "njengomholi wokulahlekelwa" ukushayela ithrafikhi yabahamba ngezinyawo ezindaweni zokuthengisa - okwandisa "isikhathi sokuhlala" kanye nokusetshenziswa kwesibili emakhefini noma ezitolo. Ngaphezu kwalokho, njengoba ubuchwepheshe be-V2G (Imoto-kuya-kuGrid) bukhula, iziteshi ezingu-150kW zingase zithole imali engenayo ngokuhlinzeka ngokulawulwa kwemvamisa kanye nezinye izinsizakalo ezihambisanayo kugridi. Ukuze kubalwe i-ROI, abaqhubi kumele babikezele amazinga okusetshenziswa - iphesenti losuku ishaja esetshenziswa ngalo ngempela. Ishaja engu-150kW ngokuvamile idinga izinga lokusetshenziswa elingu-15% kuya ku-20% ukuze likhule ngisho naphakathi kweminyaka emi-3 kuya kwemi-5, kucatshangwa ukuthi kukhona ukusabalala okufanelekile phakathi kwamanani okuthenga nokuthengisa kagesi.

Isahluko 10: Amasu Okufaka kanye Nokusebenza Kwesikhathi Eside Nokulungisa (O&M)

Ukushintsha kusuka empahleni ethengiwe kuya esiteshini sokushaja okusheshayo se-DC esingu-150kW kuyindlela eyinkimbinkimbi edinga ukuhlela ngokucophelela kanye nokuzibophezela kwesikhathi eside ekulungiseni. Ukufakwa akuyona into "yokuxhuma nokudlala"; kuyiphrojekthi yobunjiniyela ehlanganisa imikhakha eminingi. Isigaba sokukhetha indawo kumele sibheke ukufinyeleleka—ukuqinisekisa ukuthi ama-EV namaveni amade angangena kalula endaweni yokushaja ngaphandle kokuvimba ithrafikhi. Ukuqondiswa ngokomzimba kweshaja kufanele kunciphise ukucindezeleka kwekhebula; iyunithi engabekwanga kahle iholela ekutheni izintambo zidonswe ngaphesheya komgwaqo, okubangela ukuguguleka kwangaphambi kwesikhathi kuma-insulation kanye namakhanda okuxhuma.

Izinto okufanele uzicabangele ngobunjiniyela bokwakha nazo zibaluleke kakhulu. Isisekelo sekhonkrithi seyunithi engu-150kW kumele sakhiwe ukuze sisekele isisindo sekhabhinethi (esingadlula ama-500kg amayunithi e-modular) futhi simelane nemithwalo yomoya ezindaweni eziveziwe. Ukuhamba komsele ongaphansi komhlaba kumele kube nosayizi wezintambo zethusi noma ze-aluminium ezinamandla aphezulu, ngokuqaphela ngokucophelela ama-radii agobile ukuze kuvinjelwe umonakalo wokushisa. Ezimweni ezibandayo, ukulandelela ukushisa kwamapayipi noma isisekelo kungadingeka ukuvimbela ukwanda kweqhwa ekulimazeni ukuxhumana kukagesi. Ukukhanyisa kungenye into ebalulekile kodwa evame ukunganakwa; isiteshi esikhanyiswe kahle sizizwa siphephile kubasebenzisi ebusuku futhi kusiza amakhamera ahlanganisiwe (uma ekhona) ukuthi athwebule izithombe ezicacile zokuphepha nokuvimbela ukucekelwa phansi.

Uma isiteshi sesivuselelwe amandla, ukugxila kushintshela ku-Operations and Maintenance (O&M). Isu le-O&M elisebenzayo yilona elihlukanisa indawo enenzuzo nesibopho. Sihlukanisa ukulungiswa ngezinhlobo ezintathu: ukuvimbela, ukulungisa, kanye nokubikezela. Ukugcinwa kokuvimbela kuhilela ukuvakashelwa kwesayithi okuhleliwe—ngokuvamile njalo ezinyangeni eziyisithupha—ukwenza imisebenzi efana nokuhlanza noma ukushintsha izihlungi zomoya, ukuhlola i-torque ekuphelisweni kukagesi (okungakhululeka ngokuhamba kwesikhathi ngenxa yokujikeleza kokushisa), kanye nokuhlola izintambo zokushaja ukuze kutholakale ukuthi azinawo yini ama-nick noma ama-cut. Siphinde sincome “ukuhlanza okujulile” njalo endaweni ebiyelwe ukuze kususwe ukwakheka kothuli kanye nokungcola okungavimbela ukushabalaliswa kokushisa.

Ukulungiswa kokulungisa kuyimpendulo yokwehluleka kwangempela. Ukuba neSivumelwano Sezinga Lesevisi (i-SLA) nosonkontileka kagesi wendawo kubalulekile ukuqinisekisa ukuthi izinkinga ezibalulekile ziyaxazululwa zingakapheli amahora angama-24 kuya kwangu-48. Kumashaja e-modular angu-150kW, ukulungiswa kokulungisa kuvame ukuhilela ukushintsha imojuli yamandla, kodwa kungafaka futhi ukulungisa isikrini esiphukile noma ukufaka esikhundleni isibambo sokushaja esonakele. Ukulungiswa kokubikezela kuyindlela ethuthuke kakhulu, kusetshenziswa idatha ekhiqizwe yishaja ukuze kubikezelwe ukwehluleka. Ngokuqapha izinga lokushisa langaphakathi lemojuli yamandla maqondana nomthwalo wayo, isofthiwe ingabikezela ukwehluleka kwefeni okuzayo noma i-capacitor eyonakele. Lokhu kuvumela ukushintshwa ngesikhathi sokuvakasha okuhleliwe, kugwenywe ukucima okungahleliwe kanye nokulahlekelwa kwemali engenayo okuhambisanayo kanye nokwethenjwa kwamakhasimende.

Isahluko 11: Ukuthobela, Izindinganiso, kanye Nokuqinisekisa Ikusasa Lokushaja Ama-Megawatt

Ukuzulazula endaweni yezindinganiso zomhlaba wonke kanye nemithethonqubo yendawo kungenye yezici eziyinselele kakhulu ekukhetheni ishaja esheshayo engu-150kW DC. Ukuthobela imithetho akukhona nje ukuphepha; kumayelana nokusebenzisana kanye nokuvikelwa ngokomthetho. ENyakatho Melika, isitifiketi se-UL (Underwriters Laboratories) siyindinganiso yegolide, ikakhulukazi i-UL 2202 yemishini yokushaja ye-DC kanye ne-UL 2231 yezinhlelo zokuvikela abasebenzi. EYurophu nakwezinye izifunda eziningi, ukumakwa kwe-CE kanye nokunamathela ochungechungeni lwezindinganiso ze-IEC 61851 kanye ne-IEC 62196 kuyimpoqo.

Ngale kokuphepha kukagesi okuyisisekelo, abathengi kumele bacabangele amazinga okumetha. Ezindaweni eziningi, njengeJalimane enomthetho wayo we-“Eichrecht”, imitha yamandla engaphakathi kweshaja kumele iqinisekiswe ngokomthetho futhi ibonakale kumthengi, iqinisekise ukuthi bakhokhiswa ngqo ngalokho abakutholayo. Njengoba amazwe amaningi amukela imithetho efanayo yokuvikela abathengi, ukukhetha ishaja enemitha ye-DC eqinisekisiwe kusengaphambili, enembile kakhulu kuyisinyathelo esibalulekile ekuqinisekiseni ukutshalwa kwezimali kwakho esikhathini esizayo. Ngaphezu kwalokho, ukuphepha kwe-cybersecurity sekuba yinto ebaluleke kakhulu ekulawulweni. Amashaja ayizindawo zokungena kugridi kanye nenethiwekhi yomhlinzeki wesevisi; kumele asebenzise ukubethela okuqinile (i-TLS 1.2 noma ngaphezulu), izinqubo zokuqalisa ezivikelekile, kanye nama-patches okuphepha avamile ukuvikela ekuqhekekeni nasekuphulweni kwedatha.

Ukuvikela ikusasa kusho nokubheka phambili esizukulwaneni esilandelayo sobuchwepheshe be-EV. Nakuba i-150kW okwamanje "ishesha," imboni isivele isiya ku-350kW ngisho ne-Megawatt Charging Systems (MCS) yamaloli asindayo. Umthengi ocabanga phambili uzokhetha ipulatifomu engu-150kW "engathuthukiswa." Lokhu kungasho ikhabethe elinezikhala ezingenalutho zamamojula wamandla engeziwe, noma uhlelo oluklanyelwe "ukuxhumanisa okuhambisanayo," lapho amayunithi amabili angu-150kW angahlanganiswa khona ukuze alethe i-300kW emotweni eyodwa uma kudingeka. Ngaphezu kwalokho, ukwesekwa kwe-ISO 15118-20 (inguqulo yakamuva yendinganiso yokuxhumana) kuzodingeka ukuze kuvunyelwe izici ezithuthukisiwe njengokushaja okuqondiswayo (V2G/V2H) kanye nokuhlanganiswa kwegridi okuyinkimbinkimbi kakhulu.

Esinye isici sokuvikela ikusasa ukusimama kwemvelo. Izinto ezisetshenziswa ekwakhiweni kweshaja—i-aluminium ephinde isetshenziswe vs. insimbi ependiwe, uhlobo lwe-coolant esetshenziswa ezinhlelweni zoketshezi—zizothinta kakhulu iziqinisekiso “eziluhlaza” zesiteshi. Abanye abaqhubi sebevele befaka ama-canopies elanga phezu kwamashaja abo angu-150kW. Lokhu akugcini nje ngokuhlinzeka ngomthunzi kanye nokuvikelwa kwemvula kubasebenzisi kodwa futhi kukhiqiza amandla ahlanzekile angafakwa ngqo ebhasini le-DC leshaja, kunciphisa ukulahlekelwa kokudlulisela futhi kuthuthukise ukusebenza kahle kwendawo.

Isahluko 12: Isiphetho: Ukwenza Ukutshalwa Kwezimali Okuhlelekile Kwingqalasizinda ye-DC engu-150kW

Ukukhetha ishaja esheshayo engu-150kW DC kuyisinqumo esinezici eziningi esisezinhlanganweni zobunjiniyela kagesi, ukuhlanganiswa kwesofthiwe, kanye nesu lebhizinisi. Kuyo yonke le mhlahlandlela, sihlole izici zobuchwepheshe ezihlukanisa isiteshi sekhwalithi ephezulu nesithembekile kwesijwayelekile. Sibonile ukuthi i-modularity iyisisekelo sokuthembeka, ukuphathwa kokushisa okuthuthukisiwe kuyisihluthulelo sokuphila isikhathi eside, kanye nokuhambisana ne-OCPP kuyindlela yokuguquguquka.

Umkhawulo ongu-150kW umele ukukhetha okuhlakaniphile. Ishesha ngokwanele ukwanelisa isidingo somshayeli we-EV wesimanje "sokwengeza" okusheshayo, kodwa ingabizi kakhulu futhi kulula ukuyisebenzisa kunezinhlelo ezingu-350kW ezishesha kakhulu. Kumthengi, impumelelo yalolu tshalomali incike ekubhekeni ngale kwentengo yokuqala yokuthenga. Inani langempela liseZindleko Eziphelele Zobunikazi—ikhono leshaja lokugcina isikhathi esiphezulu sokusebenza, ukuzivumelanisa namamodeli ezimoto ezintsha, nokukhiqiza imali engenayo eqhubekayo ngokuphathwa kwamandla ahlakaniphile kanye nezinsizakalo ezengeziwe zenani.

Njengoba isimo se-EV siqhubeka nokuguquka ngesivinini esikhulu, izinqumo ezenziwe namuhla zizosebenza iminyaka eyishumi noma ngaphezulu. Ngokubeka phambili ukuphepha, ukusebenza kahle, kanye nokukhula, kanye nokusebenzisana nabakhiqizi abadumile abahlinzeka ngokusekelwa okuqinile kwe-O&M, abatshalizimali bangakha inethiwekhi yokushaja engagcini nje ngokuhlangabezana nezidingo zabashayeli banamuhla kodwa futhi elungele izinselele zakusasa. Ukushintshela ekuhambeni kukagesi kuwumjaho we-marathon, hhayi i-sprint, futhi ishaja esheshayo engu-150kW DC ingenye yamathuluzi anamandla kakhulu esiwasebenzisa ukuqinisekisa ukuthi uhambo luyaphumelela.
