Isikhokelo esipheleleyo soMthengi woBugcisa kwiZitishi zokuTshaja eziKhawulezayo ze-150kW DC: Ukuhamba kwiindlela zoLwakhiwo lwaMandla eziModular, ukuHlanganisa iiGrid, uLawulo loBushushu, iiNkqubo zoKhuselo lweeLayero ezininzi, ukusebenzisana kwe-OCPP, kunye neeModeli zeNgeniso eziKhululekileyo zeZakhiwo ze-EV eziQinisekisa iXesha elizayo

Isahluko 1: Intshayelelo: Ukunyuka kokutshaja okukhawulezileyo kwe-150kW DC kwi-Global EV Landscape

Utshintsho lwehlabathi oluya ekuhambeni kombane alusengomkhwa ongaphandle kodwa luyintsika ephambili yomgaqo-nkqubo wemozulu wamazwe ngamazwe kunye nesicwangciso semizi-mveliso. Njengoko ukuvinjelwa kweenjini zomlilo zangaphakathi (i-ICE) kusanda kwiimarike ezinkulu kwaye ukwamkelwa kwezithuthi zombane (ii-EV) ngabathengi kukhawulezisa, imfuno yeziseko zokutshaja eziqinileyo, ezinokuthenjwa, nezikhawulezayo ifikelele kwinqanaba eliphezulu. Ngaphakathi kwezixhobo zokubonelela ngezithuthi zombane (i-EVSE), itshaja ekhawulezayo ye-150kW DC ivele njengendawo “emnandi” kubaqhubi bezorhwebo, abaphathi beenqwelo moya, kunye nababoneleli beenkonzo zikawonke-wonke.

Ngokungafaniyo neetshaja ze-AC ezinamandla aphantsi ezifanelekileyo ukusetyenziswa ebusuku, okanye iitshaja ze-350kW+ ezinamandla aphezulu kakhulu okwangoku ezigcinelwe iimoto zodidi oluphezulu kunye neelori ezithwala abantu abaninzi, isikhululo se-150kW sinika isicwangciso esilinganayo. Sibonelela ngamaxesha okutshintsha ngokukhawuleza kakhulu kuneeyunithi ze-50kW—ehlala igcwalisa i-80% yebhetri ye-EV yanamhlanje ngaphantsi kwemizuzu engama-30—ngexesha igcina indawo elawulekayo kunye neemfuno zegridi. Oku kuyenza ibe yeyona ifanelekileyo kwizikhululo zeenkonzo zeendlela ezinkulu, kwiindawo zokuthengisa, nakwiindawo "zokugcwalisa ngokukhawuleza" zasezidolophini.

Nangona kunjalo, ukukhetha itshaja eyi-150kW efanelekileyo ayikokukhetha nje uphawu kwikhathalogu. Ibandakanya ukuqonda okunzulu nge-elektroniki yamandla, iteknoloji yokupholisa, iiprotokholi zesoftware, kunye nomzekelo wezoqoqosho. Iyunithi ekhethwe kakubi inokukhokelela kwiindleko eziphezulu zokulungisa, ixesha lokungasebenzi rhoqo, kunye nokuphelelwa lixesha ngokukhawuleza njengoko iteknoloji yebhetri itshintsha. Esi sikhokelo sisebenza njengolwazi olunzulu ngobuchwephesha kwihlabathi lokutshaja ngokukhawuleza kwe-150kW DC, okubonelela abathengi ngolwazi olufunekayo ukuze baqonde ubunzima bokukhetha, ukufakela, kunye nokusebenza ixesha elide.

Siza kuphonononga ukuba kutheni i-modularity isisiseko soyilo lwetshaja lwanamhlanje, indlela ulawulo oluphezulu lobushushu olukhusela ngayo ubomi bezixhobo, kunye nendlela ukuhlanganiswa ne-Open Charge Point Protocol (OCPP) kuqinisekisa ngayo ukuba utyalo-mali lwakho luhlala luguquguquka kwaye lusebenzisana. Ngaphezu koko, siza kuhlaziya iimodeli zengeniso ezenza izitishi ze-150kW zibe yimeko yeshishini esebenzayo, sijonge ngaphaya kokuthengisa okulula kwe-kilowatt-hour ukuya kwiinkonzo ezongeziweyo kunye nenkxaso yegridi.

Isahluko 2: Ukhetho loBugcisa: Ukuchaza uMda we-150kW wokusetyenziswa kwezorhwebo kunye noluntu

Xa uvavanya itshaja ekhawulezayo ye-150kW DC, into yokuqala ekufuneka uyiqwalasele ngobuchwephesha bubungakanani bombane okhoyo kwindawo yokujonga imoto. Ayizizo zonke iitshaja ze-"150kW" ezenziwe ngokulinganayo. Amandla alinganisiweyo adla ngokuba maximum ngokwethiyori afunyanwa kuphela phantsi kweemeko ezithile ze-voltage kunye neemeko zangoku. Kumthengi, ukuqonda uluhlu lwe-voltage—ngesiqhelo ukusuka kwi-200V ukuya kwi-1000V—kubalulekile. Ii-EV zanamhlanje, ezifana nezo zakhiwe kwizakhiwo ze-800V (umz., iPorsche Taycan, iHyundai IONIQ 5, iKia EV6), zifuna iitshaja ezinokugcina i-voltage ephezulu ukuze zifikelele kwisantya sazo esiphezulu sokutshaja. Itshaja elinganiselwe kwi-500V iya kuba nzima ukuhambisa i-150kW kwezi zithuthi zintsha, nto leyo ethintela ukusebenza kakuhle.

Enye into ebalulekileyo yokukhetha yindlela “yokutshaja ngaxeshanye”. Izitishi ezininzi ze-150kW zixhotyiswe ngezihlanganisi ezimbini (CCS1, CCS2, okanye CHAdeMO). Isitishi esisemgangathweni ophezulu siya kuba nokwabelana ngamandla okutshintshatshintshayo. Umzekelo, ukuba izithuthi ezimbini zixhunyiwe, isitishi kufuneka sikwazi ukwabela i-75kW nganye, okanye sibeke phambili imoto ngobuchule ngemeko yokutshaja ephantsi. Ukuqonda ubuncinci bolu lwabiwo lwamandla—nokuba lwenzeka ngokwanda kwe-10kW okanye ukwahlulwahlulwa kwe-50/50 okuzinzileyo—yinto ebalulekileyo yokwahlulahlula kobugcisa.

Umlinganiselo wonyawo kunye nomlinganiselo wokuvala nawo udlala indima ebalulekileyo. Kwiifektri zasezidolophini apho indawo iphezulu, iyunithi encinci, yonke-kwinye idla ngokukhethwa. Nangona kunjalo, kwiindawo zeendlela ezinkulu, inkqubo yolwakhiwo oluqhekekileyo (apho ukuguqulwa kwamandla kwenzeka kwikhabhinethi ekude kwaye umsebenzisi usebenzisana nesixhobo sokuhambisa esincinci) inokuba yeyona ifanelekileyo. Abathengi kufuneka baqinisekise umlinganiselo woKhuseleko lokungena (IP) kunye noKhuseleko lweMpembelelo (IK). Ukusetyenziswa esidlangalaleni ngaphandle, umlinganiselo we-IP54 okanye we-IP55 odityaniswe nomlinganiselo we-IK10 wendlu kunye nesikrini ngokubanzi uthathwa njengomgangatho weshishini wokuqina ngokuchasene nemozulu kunye nokonakaliswa.

Okokugqibela, ujongano lomsebenzisi (i-UI) kunye nokudibanisa intlawulo akunakujongwa. Itshaja ye-150kW sisixhobo sophuhliso esijongeka esidlangalaleni. Ukhetho lobuchwephesha kufuneka luquke isikrini sokuchukumisa esikhanyayo, esifundeka elangeni, inkxaso yeelwimi ezininzi, kunye nesiphelo sokuhlawula esomeleleyo esixhasa i-RFID, amakhadi etyala/edebhithi, kunye neewallets eziphathwayo. Kwimimandla emininzi, imithetho "yokufikelela evulekileyo" ngoku iyalela ukuba iitshaja mazimkele amakhadi etyala ngaphandle kokufuna usetyenziso oluthile okanye ubulungu, okwenza ukukhetha izixhobo zentlawulo ezidibeneyo kube yimfuneko yomthetho.

Isahluko 3: Amandla eModularity: Uyilo lweZakhiwo, ukuKhawuleza okuHlangeneyo, kunye nokuBuyiselwa kwakhona

Kwimihla yokuqala yokutshaja ngokukhawuleza kwe-DC, iiyunithi ezininzi zakhiwa kusetyenziswa uyilo lwe-"monolithic". Ukuba icandelo elinye langaphakathi aliphumelelanga, yonke itshaja yayingasebenzi. Namhlanje, eli shishini litshintshele kwi-modular parallel architecture, mhlawumbi yeyona nkqubela phambili yobugcisa kwiitshaja ze-150kW. Kolu yilo, imveliso ye-150kW iveliswa yinqwaba yeemodyuli zamandla ezincinci, ezinokutshintshwa ngobushushu—ngesiqhelo i-20kW, 30kW, okanye i-40kW nganye.

Iingenelo ze-modularity zintlantlu-ntathu: ukuthembeka, ukulungiselelwa, kunye nokukhula. Ngokwembono yokuthembeka, ukuba itshaja ye-150kW yenziwe ngeemodyuli ezintlanu ze-30kW kwaye imodyuli enye iyasilela, isikhululo asibi mnyama. Endaweni yoko, singena "kwimo eyonakeleyo," siqhubeka nokubonelela umsebenzisi ngamandla e-120kW. Oku kuqinisekisa ukuba umqhubi akaze abhajwe, nto leyo ibalulekileyo ekugcineni ulwaneliseko olukhulu lwabathengi kunye nodumo lwesiza.

Ukulungiswa kwayo kuphuculwe kakhulu. Endaweni yokufuna injineli enobuchule obuphezulu ukuba ichonge kwaye ilungise i-internal circuitry entsonkothileyo kwindawo, ingcali inokuyichonga nje imodyuli enengxaki ize iyitshintshe ngemizuzu. Oku kunciphisa i-Mean Time to Repair (MTTR) kwaye kunciphisa umthwalo wokuhambisa izinto ezinkulu nezinzima. Kubasebenzi abakhulu, oku kuthetha ukuba iindleko zokusebenza ziphantsi kakhulu (OPEX).

Okokugqibela, i-modularity inika indlela yokukhusela kwixesha elizayo. Umthengi unokuqala ngoqwalaselo lwe-150kW kodwa afake ikhabhinethi ekwaziyo ukugcina iimodyuli ezifikelela kwi-200kW okanye i-300kW. Njengoko imfuno ikhula kwaye umthamo wegridi uvumela, umqhubi unokufaka nje iimodyuli ezongezelelweyo ukwandisa umthamo wendawo ngaphandle kokufuna ukutshintsha isikhululo esibonakalayo okanye ukumba imisele emitsha. Le modeli "yokuhlawula njengoko ukhula" inomtsalane kakhulu kubatyali-mali abangaqinisekanga ngesantya sokwamkelwa kwe-EV kwindawo yabo ethile.

Isahluko 4: Intsebenziswano yeModyuli yamandla: Ukuphucula ukusebenza kakuhle kunye nee-Algorithms zokulinganisela umthwalo

Ubuchule betshaja ekhawulezayo ye-150kW DC abuphelelanga nje kwizixhobo zayo zamandla aluhlaza, kodwa nakwisoftware enobuchule eququzelela ukusebenzisana phakathi kweemodyuli zayo zamandla. Kwinkqubo yemodyuli, isilawuli esiphakathi sisebenza "njengengqondo," silawula indlela umbane otsalwa ngayo kwimodyuli nganye ukuze kwandiswe ukusebenza kakuhle kunye nobomi obude. Oku kufezekiswa ngee-algorithms eziphambili zokulinganisela umthwalo ezijonga impilo, ubushushu, kunye nembali yokusetyenziswa kwemodyuli nganye nganye kwi-stack.

Ukulungiswa kokusebenza kakuhle yinto ebalulekileyo ekusebenzeni kakuhle kwesikhululo sokutshaja. Uninzi lweemodyuli zamandla zinegophe lokusebenza kakuhle elifikelela kumthwalo othile—ngokuqhelekileyo phakathi kwe-50% kunye ne-80% yamandla azo alinganisiweyo. Ukuba itshaja ye-150kW inika kuphela i-30kW kwisithuthi esinebhetri epheleleyo, ukusebenzisa zonke iimodyuli kumthwalo we-20% kuya kuba yinto engasebenzi kakuhle ngenxa yokulahleka kokutshintsha okusisigxina kunye nokutsalwa kwamandla okuncedisa. Isilawuli esikrelekrele endaweni yoko siya kuzifihla iimodyuli ezine kwaye sisebenzise imodyuli enye ye-30kW kwindawo yaso yokusebenza kakuhle. Olu sebenzi "lwendlela yokulala" lunokonga amawaka ee-kilowatt-hours kwixesha lobomi betshaja, nto leyo echaphazela ngokuthe ngqo umgangatho womqhubi.

Ukulinganisela umthwalo kukwafikelela kulawulo lobushushu lweemodyuli. Ngexesha leeseshoni zamandla aphezulu, iimodyuli zivelisa ubushushu obukhulu. I-algorithm enobuchule iya kujikeleza umthwalo phakathi kweemodyuli ukuqinisekisa ukuba akukho yunithi inye isebenza ngobushushu obungaphezulu kunezinye. Ngokusasaza "uxinzelelo lobushushu" ngokulinganayo, inkqubo ithintela ukuguga kwendawo kwaye yandisa i-Mean Time Between Failures (MTBF) kuyo yonke i-power stack. Ngaphezu koko, ezi algorithms zinokubona iimpawu zokuqala zokuwohloka kwemodyuli—ezifana nokuqhuma kwevolthi engaqhelekanga okanye ubushushu obugqithisileyo kumthwalo othile—kwaye zizibeke uphawu lwazo ukuze zigcinwe ngaphambi kokuba kwenzeke ukusilela.

Kwiindawo zokuhambisa izinto ezininzi, ukusebenzisana kuya kuba nzima ngakumbi. Ikhabhathi yamandla ephakathi ekhonza ii-pedestals ezininzi kufuneka yabelane ngezixhobo zayo zemodyuli ngokusekwe kwii-curves ezahlukeneyo ze-state-of-charge (SoC) zezithuthi eziqhagamshelweyo. Ukuba esinye isithuthi sikwisigaba saso "sokutshaja okukhulu" kwaye singamkela i-150kW, ngelixa esinye sikwisigaba "sokunciphisa" samkela i-20kW kuphela, inkqubo kufuneka itshintshe iimodyuli ngaphandle kokuphazamiseka ukusuka kwenye imveliso ukuya kwenye. Oku kufuna iiprotokholi zonxibelelwano ezikhawulezayo (ezihlala zisekelwe kwi-CAN bus okanye kwi-industrial Ethernet) ngaphakathi kwitshaja ukuqinisekisa ukuba utshintsho lwamandla lwenzeka kwi-milliseconds ngaphandle kokuphazamisa iseshoni yokutshaja okanye ukuvala ukhuseleko kwicala lesithuthi.

Isahluko 5: Ulawulo oluPhambili lobushushu: Ulwelo vs. Ukupholisa umoya okunyanzelekileyo kwiiRectifiers ezinamandla aphezulu

Njengoko iitshaja zeDC ezikhawulezayo zingena kuluhlu lwe-150kW nangaphezulu, ulawulo lobushushu luba ngumceli mngeni ophambili wobunjineli. Ukuguqula i-AC ene-voltage ephezulu ukusuka kwigridi ibe yi-DC yebhetri akuphumelelanga ngokupheleleyo; ukulahleka kwamandla okumalunga ne-4% ukuya kwi-7% kubonakala njengobushushu. Kwinkqubo ye-150kW, oku kuthetha ukulawula ukuya kuthi ga kwi-10kW yokuchithwa kobushushu—okulingana nee-heaters ezininzi ezinkulu ezisebenza ngaphakathi kwebhokisi yesinyithi evaliweyo. Indlela obu bushushu obuphathwa ngayo imisela ngokuthe ngqo ukuthembeka kwetshaja, inqanaba lengxolo, kunye neemfuno zokugcinwa.

Ukupholisa umoya ngokunyanzelwa yindlela yendabuko neyona ixhaphakileyo kwiiyunithi ze-150kW. Isebenzisa iifeni zemizi-mveliso ezikhawulezayo ukutsala umoya ojikeleze iimodyuli zamandla nakwiindawo zokufudumala. Nangona ingabizi kakhulu kwaye kulula ukuyigcina, ukupholisa umoya kuneengxaki ezininzi. Okokuqala, ingenisa izinto ezingcolisayo kwindalo—uthuli, ukufuma, nomoya onetyuwa—kwii-elektroniki zangaphakathi ezibuthathaka, nto leyo ebangela ukuba kubekho izihluzi ezisemgangathweni ophezulu nezitshintsha rhoqo. Okwesibini, xa amandla ephezulu esetyenziswa, iifeni zinokuba nomsindo kakhulu, nto leyo enokuba yingxaki kwiindawo zokuhlala okanye kwiindawo zokuthengisa ezikumgangatho ophezulu. Ukunciphisa oku, abanye abavelisi basebenzisa iifeni “ezitshintsha isantya” ezinyuka kuphela xa kufuneka, kodwa umda osisiseko usahleli.

Ukupholisa ulwelo “ngumgangatho wegolide” we-elektroniki enamandla aphezulu, nangona ifumaneka kakhulu kwiitshaja ezikhawulezayo ezingama-350kW+. Nangona kunjalo, ezinye iindlela zoyilo ze-150kW eziphambili ziqala ukusebenzisa iimodyuli ezipholisiweyo lulwelo okanye iteknoloji yepleyiti ebandayo. Kwezi nkqubo, i-coolant (ngesiqhelo umxube wamanzi-glycol) ijikeleziswa ngeemodyuli zamandla, ithwala ubushushu iye kwi-radiator ekude. Oku kuvumela indawo evalekileyo evaliweyo ngokupheleleyo, ikhusela i-elektroniki kwizinto eziphilayo kwaye inciphise kakhulu ingxolo. Kubathengi abakwiimozulu ezimandundu—nokuba ziintlango ezishushu kakhulu okanye kwiindawo ezikunxweme olunomoya onetyuwa—ixabiso eliphezulu lokuqala lenkqubo yendlela yomoya epholisiweyo lulwelo okanye evaliweyo lidla ngokuthethelelwa kukugcinwa okuncitshisiweyo kunye nobomi bexesha elide bezixhobo.

Enye into ebalulekileyo ekufuneka iqwalaselwe kubushushu obuyi-150kW yintambo yokutshaja ngokwayo. Iintambo eziqhelekileyo ezingapholiyo zihlala zilinganiselwe kwi-200 Amps ngenxa yokwanda kobushushu kwiikhontraktha zobhedu. Ukuze ihambise i-150kW kwisithuthi se-400V, inkqubo kufuneka ityhale ii-375 Amps. Oku kufuna nokuba yintambo etyebileyo kakhulu, enzima, nenzima ukuyiphatha, okanye kusetyenziswe intambo epholisiweyo ngolwelo. Intambo epholisiweyo isebenzisa ulwelo olujikelezayo ukugcina isiphatho kunye nentambo zipholile, okuvumela uyilo oluncinci nolulungeleleneyo olunokusingatha i-400A okanye i-500A. Xa ukhetha itshaja ye-150kW, abathengi kufuneka bajonge ukuba iyunithi ibandakanya iintambo ezipholisiweyo okanye ukuba isebenzisa iindlela "zokunyusa" ezivumela umbane ophezulu ixesha elifutshane kulandele ukuthotywa kobushushu.

Isahluko 6: Uqhagamshelo lweGridi kunye noMgangatho waMandla: iiHarmonics, iiTransformers, kunye noGcino lwaMandla lweNdawo

Ukufakelwa kwetshaja ekhawulezayo ye-150kW DC yiprojekthi yobunjineli bokwakha njengoko kunjalo nangombane. Iyunithi enye ye-150kW itsala amandla amaninzi kwigridi yokusasaza yasekuhlaleni—idla ngokuba ngaphezulu kwesakhiwo seofisi esincinci okanye amakhaya alishumi elinesibini xa edibene. Oku kufuna ulungelelwaniso olucokisekileyo nenkampani yeenkonzo zasekuhlaleni ukuqinisekisa ukuba igridi iyakwazi ukusingatha imithwalo emikhulu ngequbuliso enxulumene nokutshaja ngokukhawuleza.

Umgangatho wamandla yeyona nto iphambili kwezobuchwepheshe kwiinkonzo zamandla. Iitshaja ezikhawulezayo zimithwalo engasebenzisi umgca othe tyaba esebenzisa ukutshintsha okukhawulezayo, okunokungenisa "iiharmoniki" kwigridi. Ezi harmoniki zinokubangela ubushushu obugqithisileyo kwiitransformer zezixhobo zamandla kunye nokuphazamiseka kwezinye izixhobo ezibuthathaka kwisekethe efanayo. Iitshaja ezikumgangatho ophezulu ze-150kW kufuneka zibe ne-Active Power Factor Correction (PFC) kunye nokucoca okuphucukileyo ukugcina iTotal Harmonic Distortion (THD) ingaphantsi kwe-5%, ihlangabezana nemigangatho efana ne-IEEE 519. Abathengi kufuneka bajonge iziqinisekiso eziqinisekisa ukuba itshaja ayizuku "ngcolisa" umbane wasekhaya, njengoko ezinye iinkonzo zinokwala uqhagamshelo kwiiyunithi ezingenazo izihluzo ezifanelekileyo.

Iziseko zophuhliso ezisemgangathweni zihlala zifuna i-transformer ezinikeleyo ukuze yehlise amandla aphakathi (umz., i-11kV okanye i-33kV) ukuya kwi-480V okanye i-400V AC efunekayo yitshaja. Le transformer mayingalingani nje kuphela ne-150kW eqhelekileyo, kodwa nomthwalo onokubakho ophezulu kunye nokwandiswa kwexesha elizayo. Ngaphezu koko, umgama phakathi kwe-transformer kunye netshaja ubalulekile; ukuhamba ixesha elide kwentambo ye-low voltage kunokubangela ukwehla okukhulu kwe-voltage kunye nokulahleka kwamandla, ukunciphisa amandla asebenzayo athunyelwa kwisithuthi kunye nokunyusa iindleko zombane zomqhubi.

Kwiindawo ezineegridi ezibuthathaka okanye “iindleko zemfuno” eziphezulu (isohlwayo sokusetyenziswa kwamandla aphezulu), indawo yokugcina amandla yasekuhlaleni iba sisisombululo esithandwayo. Ngokudibanisa itshaja ye-150kW neBattery Energy Storage System (BESS), abaqhubi banokuthi “baffer” igridi. I-BESS itshaja kancinci kwigridi ngexesha elingengomsebenzi omkhulu ize ikhuphe ngokukhawuleza ukuxhasa imfuno ye-150kW xa imoto ingena. Le ndlela “yokucheba i-peak” inokunciphisa kakhulu iindleko zokusebenza kwaye ivumele ukutshaja ngesantya esiphezulu kwiindawo apho ukuphuculwa kwegridi ngqo kuya kubiza kakhulu. Ukudibanisa oku kukhetho lobuchwephesha kufuna itshaja enoyilo lwe-DC-link olunokwamkela ngokulula igalelo elivela kwigridi nakwibhetri engashukumiyo.

Isahluko 7: Ukhuseleko Kuqala: Iindlela zoKhuselo lweZixhobo zeHardware kunye neSoftware ezinamaLeya amaninzi

Ukhuseleko ekutshajeni kwe-DC enamandla aphezulu lubaluleke kakhulu, njengoko itshaja ye-150kW isebenza kwiivolthi kunye nemisinga enokuba yingozi ukuba ayilawulwa kakuhle. Isitishi se-150kW esisemgangathweni wobungcali siquka iileya ezininzi zokhuseleko, ukusuka kwizihlanganisi ezibonakalayo ukuya kwisoftware yolawulo esekwe kwilifu. Ezi ndlela zenzelwe ukukhusela umsebenzisi, isithuthi, igridi, kunye nezixhobo zokutshaja ngokwazo kwiimpazamo.

Umaleko wokuqala lukhuseleko lwehardware ebonakalayo. Oku kuquka iiResidual Current Devices (RCDs) zohlobo B, ezinokubona zombini ii-AC kunye nee-DC leaking currents. Kwimeko yempazamo yomhlaba, ezi zixhobo zinokukhubeka kwii-milliseconds, zihlukanise itshaja kumbane. Ukongeza, itshaja kufuneka ibe nezixhobo zokukhusela ukushushu (ii-SPD) ukuze zikhusele ukubetha kombane okanye ii-grid transients. Ngaphakathi kwikhabhinethi, imodyuli nganye yamandla kufuneka ibe ne-fuse okanye i-circuit breaker yayo ukuthintela ukusilela kwendawo ukuba kungangeni kwingozi enkulu yomlilo. Intambo yokutshaja ngokwayo inee-sensors zobushushu kwintloko yesixhumi; ukuba iiphini zishushu kakhulu ngenxa yoqhagamshelo olubi okanye amaqondo obushushu aphezulu, inkqubo iya kuhla ngokuzenzekelayo umbane okanye imise iseshoni.

Umaleko wesibini lukhuseleko olusekelwe kunxibelelwano. Ukutshaja kwe-DC yanamhlanje kuxhomekeke kwiiprotokholi ze-ISO 15118 okanye ze-DIN 70121 zokuxhawulana phakathi kwetshaja kunye nesithuthi. Ngaphambi kokuba kunikezelwe i-watt enye yamandla, ezi nkqubo zimbini zenza uvavanyo lwazo. Isithuthi sichaza impilo yebhetri yaso, i-voltage ephezulu evumelekileyo, kunye nemida yamandla aphezulu. Itshaja iqinisekisa imeko yaso yangaphakathi kunye nokumelana nobushushu. Kuphela emva kokuba omabini amaqela eqinisekisile imeko "ekhuselekileyo yokuqhubeka" apho i-contactor ivala khona. Kuyo yonke iseshoni yokutshaja, olu kubetha kwentliziyo yonxibelelwano kuyagcinwa; ukuba unxibelelwano lulahlekile nokuba yi-millisecond ezimbalwa, iseshoni iyanqunyulwa ngoko nangoko ngenxa yokhuseleko.

Umaleko wesithathu kukujonga ubushushu. Iitshaja ezikhawulezayo ze-DC zisebenza ngendlela ye-“IT grid” (isolated terra), nto leyo ethetha ukuba akukho migca ye-DC emihle nembi iqhagamshelwe emhlabeni. Isixhobo sokuJonga uBushushu (IMD) sihlala silinganisa ukumelana phakathi kwebhasi ye-DC kunye ne-chassis. Ukuba ukungena komswakama okanye ukuguguleka kwentambo kubangela ukuba ubushushu buwe ngaphantsi komda othile (ngokuqhelekileyo olinganiswa ngeekhilo-ohms), i-IMD ibangela ukuvalwa kwangoko. Oku kubalulekile ekuthinteleni iingozi “zombane wokuthinta” apho umsebenzisi anokufumana uloyiko oluvela kwisingxobo sesinyithi setshaja.

Okokugqibela, ukhuseleko oluchazwe kwisoftware lubonelela ngokhuseleko olungafunekiyo. Isilawuli esiphakathi sijonga yonke idatha yesenzi—ubushushu, i-voltage, i-current, kunye nesantya sefeni—ngokuchasene neseti yee-envelopes zokhuseleko ezichazwe kwangaphambili. Ukuba nayiphi na iparameter idlula ngaphandle kwendawo ekhuselekileyo, isoftware inokuqalisa ukuvala okulawulwayo. Umzekelo, ukuba i-voltage yegridi yehla kakhulu (i-brownout), isoftware iya kuyimisa kakuhle iseshoni ukuthintela umonakalo kwizigaba zokufaka zeemodyuli zamandla. Iinkqubo eziphambili zikwanophawu "lokufumanisa i-arc flash," olusebenzisa izinzwa zokukhanya ukubona ii-arcs zombane zangaphakathi kunye nokukhubeka kwi-breaker ephambili ngaphambi kokuba umlilo uqale.

Isahluko 8: Inkqubo yeSoftware: OCPP 1.6J/2.0.1 Ukudibanisa, ukuBiza, kunye noLawulo olukude

Itshaja ekhawulezayo ye-150kW DC ayisosixhobo esizimeleyo; sisixhobo esixhunyiweyo esimele sidityaniswe nenkqubo yesoftware entsonkothileyo. Umgangatho weshishini wolu nxibelelwano yi-Open Charge Point Protocol (OCPP). Xa ukhetha itshaja, ukuqinisekisa ukuthotyelwa ngokupheleleyo kwe-OCPP 1.6J (JSON) yeyona mfuneko iphantsi, ngelixa inkxaso yomgangatho omtsha we-OCPP 2.0.1 icetyiswa kakhulu ukuze kuqinisekiswe kwixesha elizayo.

I-OCPP ivumela itshaja ("indawo yokutshaja") ukuba inxibelelane neseva ephakathi ("iNkqubo yoLawulo lweSitishi sokuTshaja" okanye i-CSMS). Olu dibaniselwano luvumela iimpawu ezibalulekileyo ezifana nokubeka esweni kude, uhlaziyo lwe-firmware, kunye nokuhlawulisa. Kumthengi, udibaniso lwe-OCPP luthetha "akukho kuvala komthengisi." Ukuba awonelisekanga ngumboneleli wakho wesoftware, ungatshintshela kwenye ngaphandle kokufuna ukutshintsha izixhobo ezibonakalayo. Olu lungelelwaniso lubalulekile ekuqineni kokusebenza kwexesha elide. Itshaja "evulekileyo" ngokwenene iya kuba nokuphunyezwa kwe-OCPP okuqinisekisiweyo yi-Open Charge Alliance (OCA), ukuqinisekisa ukuba inokuthetha ngokulula nayo nayiphi na i-back-end ethobela imithetho.

Ukuhlawulisa kunye nokwenza imali kuphathwa ngolu hlobo lwesoftware. Itshaja ithumela idatha elinganisiweyo kwi-CSMS, ethi emva koko icwangcise iintlawulo ngokusekelwe kumandla asetyenzisiweyo (kWh), ixesha elichithwe (imizuzu), okanye indibaniselwano yazo zombini. Kwiimarike ezininzi, amaxabiso aguqukayo aba licebo eliphambili—ukuhlawulisa ngakumbi ngexesha leemfuno eziphezulu kwaye kunika izaphulelo xa imveliso yamandla ahlaziyekayo iphezulu. Iitshaja eziphambili ze-150kW zikwaxhasa i-“Plug & Charge” (ISO 15118-2), apho isithuthi sizichaza ngokuzenzekelayo kwitshaja, sisusa imfuneko yamakhadi e-RFID okanye ii-apps zeselfowuni. Oku kubonelela ngamava angenamthungo “afana neTesla” kumsebenzisi kwaye kwandisa ukuhanjiswa kwesitishi.

Ulawulo olukude kunye nokuxilongwa kulapho inkqubo yesoftware ibonelela khona ngexabiso eliphezulu. Isitishi se-150kW sisixhobo esixabisa kakhulu, kwaye ixesha lokungasebenzi lithetha ngokuthe ngqo ingeniso elahlekileyo. I-CSMS eqinileyo inokubonelela ngezaziso zexesha langempela zazo naziphi na iimpazamo, ivumela abaqhubi ukuba balungise imiba—efana nokuxhonywa kwesoftware okanye i-tripped breaker—ukude ngaphandle kokuthumela ingcali kwindawo. Ngaphezu koko, uhlaziyo lwe-firmware olukude luqinisekisa ukuba itshaja inokuhlala ihambelana neemodeli ezintsha ze-EV njengoko zikhutshwa. Njengoko iikhemikhali zebhetri kunye nee-curve zokutshaja zitshintsha, isoftware yetshaja kufuneka ihlaziywe ukuze kuphuculwe ukusebenza kunye nokhuseleko.

Isahluko 9: Uhlalutyo lwezoQoqosho: I-Capex, i-Opex, kunye neModeli yeNgeniso ye-150kW (i-ROI)

Ukutyala imali kwitshaja ekhawulezayo ye-150kW DC kufuna ukuqonda okucacileyo ngemeko yezemali. Ixabiso lilonke lobunini (i-TCO) lahlulwe ngokwe-Capital Expenditure (i-CAPEX) kunye ne-Operational Expenditure (i-OPEX), nganye kuzo kufuneka icwangciswe ngononophelo ukuqinisekisa imbuyekezo entle kutyalo-mali (i-ROI).

I-CAPEX ibandakanya ixabiso lokuthenga itshaja ngokwayo, ethi kwiyunithi ye-150kW esemgangathweni ophezulu iqale kwi-$30,000 ukuya kwi-$60,000 kuxhomekeke kwiimpawu kunye nomgangatho wokwakha. Nangona kunjalo, iindleko zehardware zihlala ziyi-40% ukuya kwi-50% kuphela yeendleko zokufakela zizonke. Imisebenzi yokwakha—ukufaka imisele, ii-concrete pads, kunye nee-bollards zokukhusela—zinokuba nkulu, ingakumbi kwiindawo zasezidolophini. Ukuphuculwa kombane, kubandakanya i-transformer entsha kunye ne-switchgear enamandla aphezulu, kunokongeza amashumi amawaka eedola kwibhili. Iintlawulo zemvume kunye noqhagamshelo oluvela kwinkampani yeenkonzo nazo kufuneka ziqwalaselwe. Kubathengi abaninzi, izibonelelo zikarhulumente kunye nezikhuthazo zerhafu zibalulekile ekuhlawuleni ezi ndleko zokuqala, zihlala zigubungela i-50% ukuya kwi-80% ye-CAPEX kwimimandla eneenjongo zokufakelwa kombane ngamandla.

I-OPEX yindleko eqhubekayo yokugcina isikhululo sisebenza. Eyona nto inkulu idla ngokuba yindleko yombane, engabandakanyi nje kuphela amandla asetyenzisiweyo kodwa kunye "neentlawulo zemfuno." Ezi ziintlawulo zenyanga ezisekelwe kumandla aphezulu kakhulu (kwi-kW) arekhodwe kwindawo leyo. Iseshoni enye ye-150kW inokubangela intlawulo yemfuno ephezulu esusa inzuzo evela kwiiseshoni ezininzi ezincinci. Ukulawula oku kufuna isoftware yokutshaja ekrelekrele okanye indawo yokugcina ibhetri njengoko kuxoxiwe ngayo kwiSahluko 6. Ezinye izinto ze-OPEX ziquka umrhumo wenyanga we-CSMS, uqhagamshelo lweselula kwitshaja, kunye notyelelo lolondolozo lonyaka. Umgaqo olungileyo kukubeka uhlahlo-lwabiwo mali lwe-3% ukuya kwi-5% yeendleko zehardware zolondolozo lonyaka kunye nokulungiswa.

Imodeli yengeniso yesitishi se-150kW itshintsha ngaphaya kokuthengiswa kwamandla okulula. Ngelixa "umgama nge-kWh" ungoyena mqhubi uphambili, abaqhubi abaphumelelayo batshintsha iindlela zabo zengeniso. Abanye banikezela ngexabiso "lesantya esiphezulu", apho abathengi bahlawula ixabiso eliphezulu lokufikelela kwitshaja ye-150kW xa kuthelekiswa neeyunithi ezicothayo. Abanye basebenzisa isitishi sokutshaja "njengenkokeli yokulahlekelwa" ukuqhuba ithrafikhi yeenyawo ukuya kwiindawo zokuthengisa - ukwandisa "ixesha lokuhlala" kunye nenkcitho yesibini kwiikhefi okanye kwiivenkile. Ukongeza, njengoko ubuchwepheshe be-V2G (iMoto-ukuya-kwiGrid) bukhula, izikhululo ze-150kW zinokufumana ingeniso ngokubonelela ngolawulo lwamaza kunye nezinye iinkonzo ezincedisayo kwigridi. Ukuze ubale i-ROI, abaqhubi kufuneka baqikelele amazinga okusetyenziswa - ipesenti yosuku itshaja esetyenziswa ngalo. Itshaja ye-150kW idla ngokufuna izinga lokusetyenziswa le-15% ukuya kwi-20% ukuze iphumelele kwiminyaka emi-3 ukuya kwemi-5, kuthathelwa ingqalelo ukusasazeka okufanelekileyo phakathi kwamaxabiso okuthenga nokuthengisa umbane.

Isahluko 10: Amaqhinga oFakelo kunye neMisebenzi kunye noLondolozo lwexesha elide (O&M)

Utshintsho ukusuka kwimpahla ethengiweyo ukuya kwisikhululo sokutshaja esisebenza nge-150kW DC luhambo oluntsonkothileyo olufuna ucwangciso olucokisekileyo kunye nokuzibophelela ixesha elide ekulungiseni. Ukufakela akusiyonto "yokufaka iplagi kunye nokudlala"; yiprojekthi yobunjineli ebandakanya iinkalo ezininzi. Isigaba sokukhetha indawo kufuneka siqwalasele ukufikeleleka—ukuqinisekisa ukuba ii-EV kunye neeveni ezinamavili amade zinokungena ngokulula kwindawo yokutshaja ngaphandle kokuthintela ithrafikhi. Indlela itshaja ejonge ngayo kufuneka inciphise uxinzelelo lwentambo; iyunithi ebekwe kakubi ikhokelela ekubeni iintambo zitsalwe ngaphaya kwendlela, nto leyo ebangela ukuwohloka kwangaphambi kwexesha kwiintloko ze-insulation kunye nezixhumi.

Izinto eziqwalaselwayo ngobunjineli bokwakha nazo zibaluleke ngokulinganayo. Isiseko sekhonkrithi seyunithi ye-150kW kufuneka senziwe ngendlela yokuba sixhase ubunzima bekhabhathi (esinokudlula i-500kg kwiiyunithi zemodyuli) kwaye simelane nemithwalo yomoya kwiindawo ezivezwe. Ukuhamba kombhobho ongaphantsi komhlaba kufuneka kube nobukhulu beentambo zobhedu okanye ze-aluminium ezinomthamo ophezulu, kuthathelwe ingqalelo ngononophelo kwiimitha ezigobileyo ukuthintela umonakalo wobushushu. Kwimozulu ebandayo, ukulandelela ubushushu beemibhobho okanye isiseko kunokufuneka ukuthintela ukunyuka kweqabaka ekonakaliseni uqhagamshelo lombane. Ukukhanyisa yenye into ebalulekileyo kodwa edla ngokungajongwa; isikhululo esikhanyiswe kakuhle siziva sikhuselekile kubasebenzisi ebusuku kwaye sinceda iikhamera ezihlanganisiweyo (ukuba zikhona) ukuba zibambe imifanekiso ecacileyo yokhuseleko kunye nokuthintela ukonakaliswa.

Nje ukuba isikhululo sinikwe amandla, ingqwalasela itshintshela kwiMisebenzi kunye noLondolozo (O&M). Icebo le-O&M elisebenzayo lelo lahlula indawo enenzuzo kwityala. Sihlulahlula ulondolozo lube ziintlobo ezintathu: oluthintelayo, olulungisayo, noluqikelelayo. Ulondolozo oluthintelayo lubandakanya ukutyelela indawo okucwangcisiweyo—ngokuqhelekileyo rhoqo emva kweenyanga ezintandathu—ukwenza imisebenzi efana nokucoca okanye ukutshintsha izihluzi zomoya, ukujonga i-torque kwiiphelo zombane (ezinokukhululeka ngokuhamba kwexesha ngenxa yokujikeleza kobushushu), kunye nokuhlola iintambo zokutshaja ukuba azinazo izikhonkwane okanye ukunqunyulwa. Sikwacebisa "ukucoca nzulu" rhoqo kwendawo ebiyelweyo ukuze kususwe uthuli kunye nokungcola okunokuthintela ukusasazwa kobushushu.

Ukulungiswa kombane yindlela yokusabela xa kukho ukusilela. Ukuba neSivumelwano seNqanaba leNkonzo (i-SLA) nomphathi wombane wasekuhlaleni kubalulekile ukuqinisekisa ukuba imiba ebalulekileyo iyasonjululwa kwiiyure ezingama-24 ukuya kwezingama-48. Kwiitshaja ze-modular 150kW, ukulungiswa kombane kudla ngokubandakanya ukutshintshiselana ngemodyuli yamandla, kodwa kunokubandakanya ukulungisa isikrini esaphukileyo okanye ukutshintsha isiphatho sokutshaja esonakeleyo. Ukulungiswa kombane yeyona ndlela iphambili, kusetyenziswa idatha eveliswe yitshaja ukuze kuqikelelwe ukusilela. Ngokujonga ubushushu bangaphakathi bemodyuli yamandla ngokumalunga nomthwalo wayo, isoftware inokuqikelela ukusilela kwefeni okuzayo okanye i-capacitor eyonakeleyo. Oku kuvumela ukutshintshwa ngexesha lotyelelo olucwangcisiweyo, kuthintelwe ukucima okungacwangciswanga kunye nokulahleka kwengeniso kunye nokuthenjwa kwabathengi.

Isahluko 11: Ukuthobela, iMigangatho, kunye noBungqina beXesha elizayo bokuTshaja iiMegawatt

Ukuhambahamba kwimigangatho yamazwe ngamazwe kunye nemithetho yasekuhlaleni yenye yezona zinto zinzima xa ukhetha itshaja ekhawulezayo ye-150kW DC. Ukuthobela imithetho akupheleli nje ekukhuselekeni; kumalunga nokusebenzisana kunye nokukhuselwa ngokomthetho. EMntla Melika, isiqinisekiso se-UL (Underwriters Laboratories) sisona siseko segolide, ngakumbi i-UL 2202 yezixhobo zokutshaja ze-DC kunye ne-UL 2231 yeenkqubo zokukhusela abasebenzi. EYurophu nakwezinye iindawo ezininzi, ukumakishwa kwe-CE kunye nokunamathela kuluhlu lwemigangatho ye-IEC 61851 kunye ne-IEC 62196 kuyimfuneko.

Ngaphaya kokhuseleko olusisiseko lombane, abathengi kufuneka baqwalasele imigangatho yemetrology. Kwimimandla emininzi, njengeJamani enomthetho wayo we-"Eichrecht", imitha yamandla engaphakathi kwitshaja kufuneka iqinisekiswe ngokusemthethweni kwaye ibonakale kumthengi, iqinisekise ukuba bahlawuliswa kanye ngoko bakufumanayo.

Ngaphezu koko, ukhuseleko lwe-cyber luba yinto ephambili kulawulo. Iitshaja ziindawo zokungena kwigridi nakwinethiwekhi yomboneleli wenkonzo; kufuneka zisebenzise ukubethela okuqinileyo (TLS 1.2 okanye ngaphezulu), iinkqubo zokuqalisa ezikhuselekileyo, kunye neepatches zokhuseleko rhoqo ukukhusela ngokuchasene nokuqhekezwa kwedatha.

Ukukhusela ikamva kuthetha ukujonga phambili kwisizukulwana esilandelayo sobuchwepheshe be-EV. Nangona i-150kW okwangoku "ikhawuleza," eli shishini sele lisiya kwi-350kW kwaneMegawatt Charging Systems (MCS) yeelori ezinzima. Umthengi ocinga phambili uya kukhetha iqonga le-150kW "elinokuphuculwa." Oku kunokuthetha ikhabhinethi eneendawo ezingenanto zeemodyuli zamandla ezingaphezulu, okanye inkqubo eyenzelwe "ukudibanisa okulinganayo," apho iiyunithi ezimbini ze-150kW zinokudityaniswa ukuhambisa i-300kW kwisithuthi esinye ukuba kuyimfuneko. Ukongeza, inkxaso ye-ISO 15118-20 (inguqulelo yamva nje yomgangatho wonxibelelwano) iya kufuneka ukuze kusebenze iimpawu eziphambili ezifana nokutshaja kwe-bi-directional (V2G/V2H) kunye nokuhlanganiswa kwegridi okuntsonkothileyo.

Enye into yokukhusela ikamva kukuzinza kokusingqongileyo. Izinto ezisetyenziswa ekwakhiweni kwetshaja—i-aluminium ephinda isetyenziswe ngokuchasene nentsimbi epeyintiweyo, uhlobo lwesipholisi esisetyenziswa kwiinkqubo zolwelo—ziya kuba nefuthe elikhulu kwiziqinisekiso “eziluhlaza” zesikhululo. Abanye abaqhubi sele befaka ii-canopies zelanga phezu kweetshaja zabo ze-150kW. Oku akupheleli nje ekunikezeleni umthunzi kunye nokukhuselwa kwemvula kubasebenzisi kodwa kukwavelisa amandla acocekileyo anokondliwa ngqo kwibhasi ye-DC yetshaja, ukunciphisa ilahleko zothumelo kunye nokuphucula ukusebenza kakuhle kwendawo.
