Ubuyobozi bwuzuye bw'abaguzi ba tekiniki kuri sitasiyo zo gushyushya vuba za 150kW DC: Gukoresha uburyo bwo gushyushya ingufu za modular, guhuza grid, gucunga ubushyuhe, uburyo bwo kurinda amashanyarazi mu byiciro byinshi, gukoresha OCPP hamwe, n'uburyo bwo kwinjiza amafaranga menshi mu bikorwa remezo bya EV bidahinduka mu gihe kizaza.

Igice cya 1: Intangiriro: Izamuka rya 150kW DC ryo Gusharija Byihuse mu Iterambere ry'Isi rya EV

Impinduka ku isi yose ku bijyanye no gutwara amashanyarazi ntabwo ikiri ikintu cyo hanze ahubwo ni inkingi nyamukuru ya politiki mpuzamahanga y’imihindagurikire y’ikirere n’ingamba z’inganda. Uko amategeko agenga moteri zikoresha umuriro w’imbere (ICE) akomeje kugaragara mu masoko akomeye no gukoresha imodoka zikoresha umuriro w’amashanyarazi (EV) byihuta, icyifuzo cy’ibikorwa remezo bikomeye, byizewe kandi bikoresha amashanyarazi yihuta cyageze ku rwego rwo hejuru. Mu rwego rw’ibikoresho bitanga amashanyarazi (EVSE), charger yihuta ya 150kW DC yagaragaye nk'ahantu heza cyane ku bakora ubucuruzi, abayobozi b’amato, n’abatanga serivisi za leta.

Bitandukanye na charger za AC zikoresha ingufu nke zikwiriye gukoreshwa mu rugo nijoro, cyangwa charger za 350kW+ zikoresha ingufu nyinshi ubu zigenewe imodoka zihenze cyane n'amakamyo maremare, sitasiyo ya 150kW itanga uburyo bwo kugabanya ubukana. Itanga igihe cyo guhindura vuba cyane kurusha 50kW—akenshi yongera 80% bya bateri ya EV igezweho mu minota iri munsi ya 30—mu gihe ikomeza gukoresha ingufu zisanzwe n'umuyoboro w'amashanyarazi. Ibi bituma iba nziza cyane kuri sitasiyo za serivisi zo mu muhanda, aho bagurisha ibicuruzwa, n'ahantu ho mu mijyi “hashyirwa imbaraga vuba”.

Ariko, guhitamo charger ikwiye ya 150kW si ikibazo cyo guhitamo ikirango gusa muri kataloge. Bikubiyemo gusobanukirwa byimbitse ikoranabuhanga rikoresha ingufu, ikoranabuhanga ryo gukonjesha, porogaramu za porogaramu, n'uburyo bwo gukora igenamigambi ry'ubukungu. Imashini idatoranijwe neza ishobora gutuma ikiguzi cyo kuyisana gizamuka, igihe cyo kuyikoresha kenshi, ndetse no kuyisaza vuba uko ikoranabuhanga rya bateri rigenda ritera imbere. Iyi gahunda ifasha abaguzi kumenya neza isi yo gushyushya vuba ya 150kW DC, ibaha ubumenyi bukenewe kugira ngo bamenye uburyo bwo guhitamo, kuyishyiraho, no kuyikoresha igihe kirekire.

Tuzasuzuma impamvu modularity ari inkingi y'ingenzi mu gushushanya charger igezweho, uburyo imicungire y'ubushyuhe igezweho irinda igihe cyo kubaho cy'ibikoresho, n'uburyo guhuza na Open Charge Point Protocol (OCPP) bituma ishoramari ryawe rikomeza kuba ryiza kandi rishobora gukoreshwa. Byongeye kandi, tuzasesengura uburyo bwo kwinjiza amafaranga butuma sitasiyo za 150kW ziba ubucuruzi bushoboka, tukareba kurenza kugurisha kilowatt-saa gusa kugeza kuri serivisi zongerewe agaciro n'inkunga y'amashanyarazi.

Igice cya 2: Guhitamo Tekiniki: Gusobanura Umupaka wa 150kW wo Gukoreshwa mu Bucuruzi no mu Rubanda

Mu gusuzuma charger yihuta ya 150kW DC, ikintu cya mbere cyo kwitaho mu rwego rwa tekiniki ni ubushobozi nyabwo bwo gutanga kuri interineti y'imodoka. Charger zose za "150kW" si ko zingana. Ingufu zitangwa akenshi ziba ari ntarengwa mu buryo bw'imitekerereze gusa iyo habayeho voltage yihariye n'imiterere y'ubu. Ku muguzi, gusobanukirwa ingano y'voltage—ubusanzwe 200V kugeza 1000V—ni ingenzi cyane. EV zigezweho, nk'izishingiye ku miterere ya 800V (urugero, Porsche Taycan, Hyundai IONIQ 5, Kia EV6), zisaba charger zishobora kugumana voltage nyinshi kugira ngo zigere ku muvuduko wazo wo gushyushya. Charger ifite 500V izagorwa no gutanga 150kW kuri izi modoka nshya, bityo bikabangamira imikorere.

Ikindi kintu cy'ingenzi mu guhitamo ni ubushobozi bwo "gutanga amashanyarazi icyarimwe". Sitasiyo nyinshi za 150kW zifite imiyoboro ibiri (CCS1, CCS2, cyangwa CHAdeMO). Sitasiyo nziza izaba ifite amashanyarazi ahindagurika. Urugero, niba imodoka ebyiri zicanye, sitasiyo igomba kuba ishobora gutanga 75kW kuri buri imwe, cyangwa igashyira imbere imodoka ifite imiterere yo hasi y'amashanyarazi. Gusobanukirwa ubunini bw'aya mashanyarazi—byaba bibaye mu nyongera za 10kW cyangwa mu gutandukana kwa 50/50—ni ikintu cy'ingenzi mu gutandukanya aya mashanyarazi.

Isuzuma ry’aho ibintu biherereye n’aho biherereye nabyo bigira uruhare runini. Ku bijyanye n’aho ibintu biherereye mu mijyi aho umwanya uri ku rwego rwo hejuru, akenshi ni byo bikunze gukundwa. Ariko, ku mihanda minini, sisitemu yo kubaka ahantu hatandukanye (aho amashanyarazi ahinduka mu kabati ka kure kandi umukoresha agakoresha icyuma gitanga umuriro muto) ishobora kuba ikwiriye kurushaho. Abaguzi bagomba kandi kugenzura amanota yo kurinda ingress (IP) na Impact Protection (IK). Ku bikorwa rusange byo hanze, amanota ya IP54 cyangwa IP55 hamwe n’amanota ya IK10 ku mazu na ecran muri rusange bifatwa nk'urugero rw’inganda mu kuramba kw’ikirere n’ubwangizi.

Hanyuma, uburyo bwo gukoresha (UI) no guhuza uburyo bwo kwishyura ntibishobora kwirengagizwa. Ishaje ya 150kW ni igice cy’ibikorwa remezo gikoreshwa na rubanda. Amahitamo ya tekiniki agomba kuba arimo ecran igaragara cyane, isomwa n’izuba, inkunga y’indimi nyinshi, hamwe n’icyuma gikomeye cyo kwishyura gishyigikira RFID, amakarita y’inguzanyo/debiti, n’ama-wallets akoresha telefoni. Mu turere twinshi, amategeko "y’abakoresha bose" ubu ategeka ko abakoresha shaje bagomba kwakira amakarita y’inguzanyo badasabye porogaramu cyangwa ubunyamuryango bwihariye, bigatuma guhitamo ibikoresho byo kwishyura bihujwe biba ngombwa mu mategeko.

Igice cya 3: Imbaraga za Modularity: Ubwubatsi, Ubunini bujyanye n'igihe, n'Uburyo bwo kongera gukoresha

Mu minsi ya mbere yo gushyushya vuba DC, units nyinshi zubatswe hakoreshejwe imiterere ya "monolithic". Iyo igice kimwe cy'imbere cyananirwaga, charger yose yacikaga. Muri iki gihe, inganda zahinduye urwego rw'imiterere ya modular parallel, ishobora kuba ari yo ntambwe ikomeye mu ikoranabuhanga rya charger za 150kW. Muri ubu buryo, umusaruro wa 150kW uturuka ku murundo w'ingufu nto, zishobora guhindurwa zishyushye—ubusanzwe 20kW, 30kW, cyangwa 40kW imwe.

Ibyiza byo gukoresha modularity ni bitatu: kwizerwa, serivisi nziza, no kwaguka. Mu rwego rwo kwizerwa, iyo charger ya 150kW igizwe na module eshanu za 30kW kandi module imwe ikananirwa, sitasiyo ntijya yijima. Ahubwo, yinjira mu "mode yangiritse", ikomeza gutanga ingufu za 120kW ku mukoresha. Ibi byemeza ko umushoferi atazigera abura aho anyura, ibi bikaba ari ingenzi cyane kugira ngo abakiriya bakomeze kunyurwa no kumenyekana kw'urubuga.

Serivisi nayo irarushaho kuba nziza cyane. Aho gusaba injeniyeri w’inzobere mu gusuzuma no gusana uburyo bugoye bwo gupima no gusana imikorere y’imbere mu rugo, umutekinisiye ashobora kumenya gusa module ifite ikibazo hanyuma akayihindura indi mu minota mike. Ibi bigabanya igihe cyo gusana (MTTR) kandi bigabanya umutwaro wo kubika ibikoresho binini kandi biremereye. Ku bakoresha banini, ibi bivuze ko amafaranga akoreshwa mu bikorwa agabanuka cyane (OPEX).

Amaherezo, modularity itanga inzira yo kuzigama mu gihe kizaza. Umuguzi ashobora gutangirana na configuration ya 150kW ariko agashyiraho akabati gashobora kwakira modules zigera kuri 200kW cyangwa 300kW. Uko icyifuzo kigenda cyiyongera n'ubushobozi bwa grid bubyemera, umukoresha ashobora kongeramo modules kugira ngo yongere ubushobozi bw'aho hantu hatabayeho gusimbuza sitasiyo yose cyangwa gucukura imiyoboro mishya. Ubu buryo bwo "kwishyura uko ugenda ukura" burakurura cyane abashoramari batazi neza igipimo cyihuse cyo gukoresha amashanyarazi mu gace kabo.

Igice cya 4: Ihuriro ry'ingufu: Uburyo bwo kunoza imikorere n'uburyo bwo kuringaniza imitwaro

Ubwenge bwa 150kW DC yihuta ntabwo buri mu bice byayo by'ingufu gusa, ahubwo buri muri porogaramu igezweho ihuza modules zayo z'ingufu. Muri sisitemu ya modular, ikigo cy'igenzura gikorera nk' "ubwonko," gicunga uburyo ingufu zituruka kuri buri module zikoreshwa kugira ngo cyongere imikorere myiza no kuramba. Ibi bigerwaho binyuze mu buryo bugezweho bwo guhuza imizigo bukurikirana ubuzima, ubushyuhe, n'amateka y'ikoreshwa rya buri module mu buryo nyabwo.

Gukoresha neza imikorere ni ikintu cyingenzi kugira ngo sitasiyo yo gusharija ishobore gukora neza. Module nyinshi z'amashanyarazi zifite umurongo upima imikorere ku mutwaro runaka—akenshi hagati ya 50% na 80% by'ubushobozi bwazo. Niba charger ya 150kW itanga 30kW gusa ku modoka ifite bateri hafi yuzuye, gukoresha module zose ku mutwaro wa 20% byaba bidakora neza cyane bitewe n'igihombo gihoraho cyo guhinduranya no gukoresha ingufu z'inyongera. Imashini igenzura imikorere y'ikoranabuhanga ihita ihagarika module enye kandi ikoreshe module imwe ya 30kW aho igeze ku mutwaro wayo. Ubu buryo bwo "gusinzira" bushobora kuzigama amasaha ibihumbi ya kilowatt mu gihe cyose charger ikora, bigira ingaruka ku musaruro w'umukoresha.

Gupima umutwaro no kugenzura ubushyuhe bwa modules. Mu gihe cy'imyitozo y'ingufu nyinshi, modules zitanga ubushyuhe bukabije. Algorithm ihambaye izazunguruka umutwaro hagati ya modules kugira ngo hatagira igice kimwe gihora gishyuha kurusha ibindi. Mu gukwirakwiza "stress y'ubushyuhe" ku buryo bungana, sisitemu irinda gusaza kwaho kandi yongere igihe hagati y'ingufu (MTBF) ku ngufu zose. Byongeye kandi, izi algorithm zishobora kubona ibimenyetso bya module byangiritse—nk'ingufu zidasanzwe cyangwa ubushyuhe bwinshi ku mutwaro runaka—kandi zikabishyira ahagaragara mbere yuko hagira ikibazo.

Ku hantu hakoreshwa ibikoresho byinshi, guhuza ibintu birushaho kuba ingorabahizi. Akabati k'amashanyarazi gakorera ku ntebe nyinshi gagomba gushyiraho uburyo bwa module gashingiye ku miterere itandukanye y'imodoka zihujwe. Iyo imodoka imwe iri mu cyiciro cyayo cya "bulk charge" kandi ishobora kwakira 150kW, mu gihe indi iri mu cyiciro cya "repering" yakira 20kW gusa, sisitemu igomba guhindura modules kuva kuri imwe ijya ku yindi. Ibi bisaba protocole z'itumanaho ryihuse cyane (akenshi zishingiye kuri CAN bus cyangwa industrial Ethernet) muri charger kugira ngo hamenyekane ko impinduka z'amashanyarazi ziba mu masegonda make nta guhagarika igihe cyo gusharija cyangwa ngo bitume imodoka ifunga umutekano.

Igice cya 5: Imicungire y'Ubushyuhe Buhanitse: Gukonjesha amazi ugereranyije n'umwuka uhatirwa ku bikoresho bitanga ingufu nyinshi

Uko charger za DC zihuta ziyongera kugera ku rugero rwa 150kW no kurenzaho, gucunga ubushyuhe biba ikibazo cy'ingenzi mu buhanga. Guhindura AC ifite voltage nyinshi kuva kuri grid ikajya muri DC kuri bateri ntabwo ari byiza 100%; igihombo cy'ingufu kiri hagati ya 4% na 7% kigaragara nk'ubushyuhe. Muri sisitemu ya 150kW, ibi bivuze gucunga kugeza kuri 10kW yo gusohora ubushyuhe—bingana n'ibyuma byinshi binini bishyushya mu gasanduku k'icyuma gafunze. Uburyo ubu bushyuhe bufatwa bugena neza uburyo charger yizewe, urwego rw'urusaku, n'ibisabwa mu kubungabunga.

Gukonjesha umwuka ku ngufu ni bwo buryo busanzwe kandi bukunze gukoreshwa ku bikoresho bya 150kW. Bukoresha amafeni yo mu nganda yihuta cyane kugira ngo bukurure umwuka wo mu kirere binyuze mu mamashini y'amashanyarazi no mu byuma bishyushya. Nubwo buhendutse kandi byoroshye kubungabunga, gukonjesha umwuka bifite imbogamizi nyinshi. Ubwa mbere, bwinjiza ibintu byanduza ibidukikije—umukungugu, ubushuhe, n'umwuka w'umunyu—mu bikoresho by'ikoranabuhanga byo mu nzu, bigasaba amafiriti meza kandi ahora ahindurwa. Icya kabiri, iyo umuriro ugeze ku rwego rwo hejuru, amafeni ashobora kuba asakuza cyane, ibyo bikaba bishobora kuba ikibazo mu duce tw'abaturage cyangwa mu maduka ahenze. Kugira ngo ibi bigerweho, bamwe mu bakora bakoresha amafeni ya “variable speed drive” yiyongera gusa iyo bibaye ngombwa, ariko imbogamizi nyamukuru iracyahari.

Gukonjesha amazi ni "igipimo cya zahabu" ku bikoresho by'ikoranabuhanga bikoresha ingufu nyinshi, nubwo bikunze kuboneka mu byuma bitanga ingufu za 350kW+ zihuta cyane. Ariko, hari imiterere imwe n'imwe ya 150kW itangiye gukoresha modules zikonjesha amazi cyangwa ikoranabuhanga rya cold-plate. Muri izi sisitemu, icyuma gikonjesha (ubusanzwe kivangwa n'amazi-glycol) gikwirakwizwa mu byuma bitanga ingufu, kijyana ubushyuhe kuri radiator iri kure. Ibi bituma habaho ahantu hafunze neza, kikarinda amashanyarazi ikirere kandi kikagabanya cyane urusaku. Ku baguzi bo mu turere dushyuha cyane - haba mu butayu bushyushye cyane cyangwa mu turere turimo umwuka umunyu - ikiguzi kinini cya sisitemu ikonjesha amazi cyangwa ifunze-umwuka akenshi kiba gifite ishingiro ryo kugabanuka kw'ibikorwa byo kubungabunga no kumara igihe kirekire ibikoresho.

Ikindi kintu cy'ingenzi gikwiye kwitabwaho ku bushyuhe bwa 150kW ni insinga yo gusharija ubwayo. Insinga zisanzwe zidakonjesha ubusanzwe zigarukira kuri Amps 200 bitewe n'ubushyuhe bwinshi mu byuma biyobora umuringa. Kugira ngo imodoka ya 400V igere kuri 150kW, sisitemu igomba gusunika Amps 375. Ibi bisaba insinga nini cyane, iremereye, kandi igoye kuyifata, cyangwa gukoresha insinga ikonjesha amazi. Insinga ikonjesha ikoresha amazi azenguruka kugira ngo igumane umugozi n'insinga bikonje, bigatuma habaho imiterere yoroshye kandi ihamye ishobora gufata 400A cyangwa 500A. Mu guhitamo charger ya 150kW, abaguzi bagomba kugenzura niba iyi mashini irimo insinga zikonjesha cyangwa niba ikoresha uburyo bwo "kongera imbaraga" butuma umuriro mwinshi umara igihe gito bigakurikirwa no gushyuha.

Igice cya 6: Guhuza imiyoboro y'amashanyarazi n'ubwiza bw'amashanyarazi: Harmoniki, Transformateur, n'ububiko bw'ingufu mu gace

Gushyiramo icyuma gishyushya cya DC cya 150kW ni umushinga w’ubwubatsi nk’uko bimeze ku bijyanye n’amashanyarazi. Imashini imwe ya 150kW ikura ingufu nyinshi mu muyoboro w’amashanyarazi wo mu gace ikoreramo—akenshi irenga inyubako nto y’ibiro cyangwa amazu cumi n’abiri hamwe. Ibi bisaba ubufatanye bwitonze n’ikigo cy’ubucuruzi cy’aho gikorera kugira ngo icyuma gishyushya umuriro gishobore guhangana n’imizigo minini kandi itunguranye ijyanye no gusharija vuba.

Ubwiza bw'amashanyarazi ni ikibazo gikomeye mu bya tekiniki ku bigo bitanga umuriro. Gushyushya vuba ni imitwaro idakoresha umurongo umwe ikoresha uburyo bwo guhinduranya ingufu (high-frequency switching), ishobora kwinjiza "harmonics" mu muyoboro w'amashanyarazi. Izi harmonics zishobora gutera ubushyuhe bwinshi mu bikoresho bitanga umuriro kandi zikabangamira ibindi bikoresho byoroheje kuri circuit imwe. Gushyushya ingufu za 150kW zigomba kuba zifite Active Power Factor Correction (PFC) na filtering igezweho kugira ngo Total Harmonic Distortion (THD) igume munsi ya 5%, byujuje ibisabwa nka IEEE 519. Abaguzi bagomba gushaka ibyemezo byemeza ko charger "itazahumanya" amashanyarazi yo mu gace, kuko bimwe mu bigo bishobora kwanga guhuza n'ibikoresho bidafite uburyo bwiza bwo kuyungurura.

Ibikorwa remezo bifatika akenshi bisaba transformateur yihariye kugira ngo igabanure ingufu za voltage iringaniye (urugero, 11kV cyangwa 33kV) kuri AC ya 480V cyangwa 400V isabwa na charger. Iyi transformateur igomba kuba ifite ingano itari iya 150kW gusa, ahubwo no kugira ngo igere ku mutwaro mwinshi ndetse no kwaguka mu gihe kizaza. Byongeye kandi, intera iri hagati ya transformateur n'charger ni ingenzi cyane; gukoresha insinga za voltage nkeya bishobora gutuma ingufu za voltage zigabanuka cyane ndetse n'igihombo cy'ingufu, bigabanura ingufu zitangwa ku modoka kandi bikongera fagitire y'amashanyarazi y'umukoresha.

Mu turere dufite imiyoboro y'amashanyarazi idakomeye cyangwa "amafaranga menshi yo gukenera" (ibihano byo gukoresha ingufu nyinshi), ububiko bw'ingufu mu gace burimo kuba igisubizo gikunzwe. Mu guhuza charger ya 150kW na Battery Energy Storage System (BESS), abakoresha bashobora "gushyira ingufu" kuri grid. BESS ishyushya buhoro buhoro kuva kuri grid mu masaha atari ay'umuvuduko hanyuma igasohoka vuba kugira ngo ishyigikire 150kW iyo imodoka ifunguye. Iyi ngamba yo "gusuka shearing peak" ishobora kugabanya cyane ikiguzi cy'imikorere no kwemerera charger yihuta ahantu aho kuvugurura grid direct byaba bihenze cyane. Kugira ngo ibi bihuzwe mu guhitamo tekiniki bisaba charger ifite imiterere ya DC-link ishobora kwakira byoroshye ibintu biva kuri grid art na bateri idahagarara.

Igice cya 7: Umutekano Mbere ya Byose: Uburyo bwo Kurinda Ibikoresho na Porogaramu mu byiciro byinshi

Umutekano mu gushyushya DC ifite imbaraga nyinshi ni ingenzi cyane, kuko charger ya 150kW ikora ku muvuduko n'imirasire y'amashanyarazi ishobora kwica iyo idacunzwe neza. Sitasiyo ya 150kW y'umwuga ikubiyemo uburinzi butandukanye, kuva ku miyoboro ifatika kugeza kuri porogaramu yo gucunga ishingiye ku bicu. Ubu buryo bwagenewe kurinda umukoresha, ikinyabiziga, grid, n'ibikoresho byo gushyushya ubwabyo amakosa.

Icyiciro cya mbere ni uburinzi bw'ibikoresho. Ibi birimo Ibikoresho bya Residual Current (RCDs) byo mu bwoko bwa B, bishobora kumenya imiyoboro ya AC na DC isohoka. Mu gihe habayeho ikibazo cy'ubutaka, ibi bikoresho bishobora kugwa mu masegonda make, bigatandukanya charger n'amashanyarazi. Byongeye kandi, charger igomba kugira ibikoresho byo kurinda surge (SPDs) kugira ngo birinde inkuba cyangwa grid transients. Mu kabati, buri module y'amashanyarazi igomba kugira fuse cyangwa circuit breaker yayo kugira ngo hirindwe ko ikibazo cyaho cyagwa kikavamo ibyago bikomeye by'inkongi. Insinga yo gusharija ubwayo irimo sensors z'ubushyuhe mu mutwe w'umuhuza; niba pin zishyushye cyane bitewe no guhuza nabi cyangwa ubushyuhe bwinshi, sisitemu izimura umuriro cyangwa igahagarika ikoreshwa ryayo.

Icyiciro cya kabiri ni umutekano ushingiye ku itumanaho. Gukoresha DC igezweho mu gusana hakoreshejwe uburyo bwa ISO 15118 cyangwa DIN 70121 bwo guhuza icyuma gitanga umuriro n'imodoka. Mbere yuko umuriro umwe wa watt utangwa, sisitemu zombi zikora isuzuma ryigenga. Ikinyabiziga kigaragaza ubuzima bwa bateri yacyo, voltage ntarengwa yemewe, n'umuvuduko w'amashanyarazi ugera ku rwego rwo hejuru. Imashini igenzura imiterere yayo imbere n'ubudahangarwa bwayo bwo gukingira. Nyuma y'uko impande zombi zemeza ko "bitekanye gukomeza" ni bwo imashini ifunga. Mu gihe cyose cyo gusana umuriro, ubu buryo bwo gusana umuriro bugumaho; iyo umurongo ubuze ndetse n'amasegonda make, isuzuma rihita rihagarara kubera umutekano.

Icyiciro cya gatatu ni ugukurikirana insulation. Imashini zishyushya vuba za DC zikora mu buryo bwa "IT grid" (terra isolated), bivuze ko nta murongo wa DC mwiza cyangwa mubi uhujwe n'ubutaka. Igikoresho cyo kugenzura insulation (IMD) gihora gipima uburinzi hagati ya DC bus na chassis. Iyo ubushuhe bwinjira cyangwa ubusaza bw'insinga butuma insulation igabanuka munsi y'umurongo runaka (ubusanzwe upimirwa muri kilo-ohms), IMD ihita ifunga. Ibi ni ingenzi mu gukumira ibyago byo "gukora ku muvuduko" aho umukoresha ashobora guhura n'impanuka iturutse ku gasanduku k'icyuma k'imashini.

Amaherezo, uburinzi bugenwa na porogaramu butanga uburinzi budasanzwe. Akamashini gashinzwe kugenzura amakuru yose ya sensor—ubushyuhe, voltage, amashanyarazi, n'umuvuduko w'umufana—ku bijyanye n'amabahasha y'umutekano yagenwe mbere. Iyo hari parametero igiye hanze y'agace gafite umutekano, porogaramu ishobora gutangiza kuzimya igenzurwa. Urugero, niba voltage ya grid igabanutse cyane (brownout), porogaramu izahagarika neza ikiganiro kugira ngo hirindwe kwangirika kw'ibyiciro by'amashanyarazi. Sisitemu zigezweho kandi zifite "arc flash detection," zikoresha sensor z'urumuri kugira ngo zimenye arc z'amashanyarazi imbere kandi zigakubita agace gakomeye mbere yuko umuriro utangira.

Igice cya 8: Porogaramu zigenga: OCPP 1.6J/2.0.1 Guhuza, Gutanga Inyemezabwishyu, no Gucunga Imicungire ya Remote

Gutanga charger ya DC ya 150kW si igikoresho cyihariye; ni igikoresho gifitanye isano n'umuyoboro kigomba kwinjizwa muri porogaramu zigoye. Ibipimo ngenderwaho by'inganda muri ubu buryo bw'itumanaho ni Open Charge Point Protocol (OCPP). Mu guhitamo charger, kugenzura ko OCPP 1.6J (JSON) yujuje ibisabwa byose ni byo bisabwa, mu gihe gushyigikira ibipimo ngenderwaho bishya bya OCPP 2.0.1 ari byiza cyane kugira ngo bigerweho mu gihe kizaza.

OCPP yemerera charger ("aho charger") kuvugana na seriveri nkuru ("System de Charging Station Management System") cyangwa CSMS. Uku guhuza bituma habaho ibintu by'ingenzi nko kugenzura kure, kuvugurura firmware, no kwishyuza. Ku muguzi, guhuza OCPP bivuze "nta mucuruzi ufungira." Niba utishimiye porogaramu yawe, ushobora guhindura ukajya ku yindi utiriwe ukenera gusimbuza ibikoresho bifatika. Ubu buryo ni ingenzi kugira ngo ukomeze gukora neza igihe kirekire. charger "ifunguye" by'ukuri izaba ifite icyemezo cy'uko OCPP ishyirwa mu bikorwa na Open Charge Alliance (OCA), ikerekana ko ishobora kuvugana neza n'abandi bose bakurikiranye ibisabwa.

Kwishyura no kwinjiza amafaranga bikorwa binyuze muri uru rwego rwa porogaramu. Iyi shajara yohereza amakuru yapimwe kuri CSMS, hanyuma igatunganya kwishyura hashingiwe ku ngufu zikoreshwa (kWh), igihe cyakoreshejwe (iminota), cyangwa byombi. Mu masoko menshi, ibiciro bihindagurika birimo kuba ingamba y'ingenzi—kwishyuza byinshi mu masaha yo gusaba cyane no gutanga igabanywa ry'ibiciro iyo umusaruro w'ingufu zishobora kuvugururwa uri hejuru. Ishajara za 150kW zigezweho nazo zishyigikira "Plug & Charge" (ISO 15118-2), aho imodoka yiyerekana kuri iyo shajara mu buryo bwikora, bigatuma hadakenerwa amakarita ya RFID cyangwa porogaramu za telefoni. Ibi bitanga ubunararibonye "bumeze nka Tesla" ku mukoresha kandi byongera umusaruro wa sitasiyo.

Gucunga no gusuzuma porogaramu za kure niho ikoranabuhanga rya mudasobwa ritanga agaciro kanini. Sitasiyo ya 150kW ni umutungo w'agaciro kanini, kandi igihe cyo gukora porogaramu gisobanura ko amafaranga yinjira yatakaye. CSMS ikomeye ishobora gutanga amakuru mu gihe nyacyo ku makosa ayo ari yo yose, bigatuma abakora porogaramu bakemura ibibazo—nk'aho porogaramu yamanitswe cyangwa aho yangiritse—bitabaye ngombwa ko bohereza umutekinisiye ku rubuga. Byongeye kandi, kuvugurura porogaramu za kure byemeza ko charger ishobora kugumana na moderi nshya za EV uko zigenda zisohoka. Uko ikoranabuhanga rya bateri n'uburyo bwo gushyushya bihinduka, porogaramu ya charger igomba kuvugururwa kugira ngo inoze imikorere n'umutekano.

Igice cya 9: Isesengura ry'Ubukungu: Capex, Opex, n'icyitegererezo cy'Imisoro cya 150kW (ROI)

Gushora imari mu ishaje ya DC ya 150kW bisaba gusobanukirwa neza imiterere y'imari. Ikiguzi cyose cy'ubunyamwuga (TCO) kigabanyijemo amafaranga akoreshwa mu bikorwa (Capital Expenditure) na OPEX, buri imwe muri zo igomba gutegurwa neza kugira ngo inyungu ku ishoramari iboneke (ROI).

CAPEX irimo igiciro cyo kugura charger ubwayo, iyo unit ifite ubushobozi bwo hejuru bwa 150kW ishobora kuva ku madolari 30.000 kugeza ku madolari 60.000 bitewe n'imiterere n'ubwiza bw'inyubako. Ariko, ikiguzi cy'ibikoresho akenshi kiba hagati ya 40% na 50% by'ikiguzi cyose cyo gushyiraho. Imirimo y'ubucuruzi—guca imiyoboro y'amazi, sima, n'ibyuma bikingira—ishobora kuba ingenzi cyane, cyane cyane mu mijyi. Kuvugurura amashanyarazi, harimo transformer nshya na switchgear ifite ubushobozi bwo hejuru, bishobora kongera amafaranga ibihumbi mirongo kuri fagitire. Amafaranga yo kwemerera no guhuza amashanyarazi atangwa n'ikigo cy'amashanyarazi na yo agomba kwitabwaho. Ku baguzi benshi, inkunga za leta n'imisoro ni ingenzi cyane mu kwishyura aya mafaranga y'ibanze, akenshi bingana na 50% kugeza 80% bya CAPEX mu turere dufite intego zikomeye zo gushyiramo amashanyarazi.

OPEX ni ikiguzi gihoraho cyo gukomeza gukora kwa sitasiyo. Igice kinini cyane ubusanzwe ni ikiguzi cy'amashanyarazi, kitarimo ingufu zikoreshwa gusa ahubwo kinakubiyemo "amafaranga yo gukenera." Aya ni amafaranga ya buri kwezi ashingiye ku ngufu nyinshi cyane (muri kW) zanditswe aho hantu. Inshuro imwe ya 150kW ishobora gutera ikiguzi kinini cyo gukenera gikuraho inyungu yavuye mu byiciro byinshi bito. Kubicunga bisaba porogaramu yo gusharija ikoresheje ubuhanga cyangwa kubika bateri yo mu gace nk'uko byavuzwe mu Gice cya 6. Ibindi bintu bya OPEX birimo ifatabuguzi rya buri kwezi rya CSMS, guhuza telefoni zigendanwa kuri charger, no gusura ibikorwa byo kubungabunga buri mwaka. Itegeko ryiza ni uguteganya ingengo y'imari ya 3% kugeza kuri 5% by'ikiguzi cy'ibikoresho byo kubungabunga no gusana buri mwaka.

Uburyo bwo kwinjiza amafaranga kuri sitasiyo ya 150kW burimo guhinduka uretse kugurisha ingufu gusa. Nubwo "inyongera kuri kWh" ari yo mpamvu nyamukuru ikoreshwa, abakora neza barimo guhindura uburyo bwabo bwo kwinjiza amafaranga. Bamwe batanga ibiciro "by'umuvuduko wo hejuru", aho abakiriya bishyura igiciro kinini cyo kubona charger ya 150kW ugereranije n'ibikoresho bitinda. Abandi bakoresha charger nk'"igihombo" kugira ngo batware urujya n'uruza rw'abanyamaguru bajya mu maduka - byongera "igihe cyo gutura" no gukoresha amafaranga make muri cafe cyangwa mu maduka. Byongeye kandi, uko ikoranabuhanga rya V2G (Mobile-to-Grid) rigenda rikura, stations za 150kW zishobora kwinjiza amafaranga binyuze mu gutanga amabwiriza agenga inshuro n'izindi serivisi zijyanye na grid. Kugira ngo babare inyungu ikomoka ku mafaranga akoreshwa, abakora bagomba guteganya igipimo cy'ikoreshwa - ijanisha ry'umunsi charger ikoreshwa koko. charger ya 150kW isanzwe ikenera igipimo cy'ikoreshwa cya 15% kugeza kuri 20% kugira ngo igabanuke mu myaka 3 kugeza kuri 5, dufashe ko hari itandukanyirizo rikwiye hagati y'ibiciro byo kugura no kugurisha amashanyarazi.

Igice cya 10: Ingamba zo gushyiraho no kubungabunga igihe kirekire (O&M)

Guhindura igikoresho cyaguzwe kikajya kuri sitasiyo yo gushyushya vuba ya 150kW DC ni urugendo rugoye rusaba igenamigambi ryimbitse n'umuhate wo kubungabunga igihe kirekire. Gushyiraho si igikorwa cyo "gushyiramo no gukina"; ni umushinga w’ubuhanga ugizwe n’amasomo menshi. Icyiciro cyo guhitamo aho hantu kigomba kuba gishingiye ku buryo abantu bashobora kugera—kugira ngo barebe ko imodoka za EV na vani zifite amapine maremare zishobora kwinjira mu cyumba cyo gushyushya bitabujije urujya n’uruza rw’imodoka. Uburyo icyuma gishyushya kigomba kugabanya uburemere bw’insinga; icyuma gishyizwe nabi gituma insinga zikururwa mu muhanda, bigatera kwangirika vuba ku byuma bikingira insinga n’imitwe y’ibikoresho.

Ibyerekeye ubwubatsi bw’ubwubatsi nabyo ni ingenzi cyane. Ishingiro rya beto ry’icyuma cya 150kW rigomba kuba rikozwe kugira ngo rifashe uburemere bw’akabati (kashobora kurenza 500kg ku bikoresho bya modular) kandi rigahangana n’umuyaga mwinshi ahantu hagaragara. Imiyoboro yo munsi y’ubutaka igomba kuba ifite ingano ikoreshwa mu nsinga z’umuringa cyangwa aluminiyumu, hitabwaho cyane imirasire yo kugonda kugira ngo hirindwe kwangirika kw’ubushyuhe. Mu bihe bikonje, gukurikirana ubushyuhe bw’imiyoboro cyangwa igice cyo hasi bishobora kuba ngombwa kugira ngo hirindwe ko ubukonje bwangiza imiyoboro y’amashanyarazi. Amatara ni ikindi kintu cy’ingenzi ariko gikunze kwirengagizwa; sitasiyo ifite urumuri rwiza yumva ifite umutekano ku bakoresha nijoro kandi igafasha kamera zirimo (niba zihari) gufata amashusho asobanutse neza kugira ngo umutekano n’umutekano birindwe kwangirika.

Iyo sitasiyo imaze gushyirwamo ingufu, hibandwa ku bikorwa no kubungabunga (O&M). Ingamba zo kubungabunga no kubungabunga ni zo zitandukanya ahantu heza n'aho habereye ikibazo. Dushyira ibikorwa byo kubungabunga mu byiciro bitatu: gukumira, gukosora, no guteganya. Gutunganya no gukumira bikubiyemo gusura ahantu hateganyijwe—ubusanzwe buri mezi atandatu—kugira ngo ukore imirimo nko gusukura cyangwa gusimbuza ibyuma bisukura umwuka, kugenzura imbaraga z'amashanyarazi ku mpera z'amashanyarazi (zishobora gucika intege uko igihe kigenda bitewe n'ubushyuhe), no kugenzura insinga zo gusharija niba hari aho zacitse cyangwa zacitse. Turasaba kandi ko habaho "gusukura cyane" buri gihe ahantu hafunganye kugira ngo dukureho ivumbi n'imyanda ishobora kubangamira ubushyuhe.

Gukosora ni igisubizo ku kibazo cy’impanuka nyayo. Kugirana amasezerano yo ku rwego rwa serivisi (SLA) n’umukozi w’amashanyarazi wo mu gace ni ingenzi kugira ngo ibibazo bikomeye bikemurwe mu masaha 24 kugeza kuri 48. Ku bijyanye na charger za modular 150kW, gutunganya neza akenshi bisaba gusa gusimbuza module y’amashanyarazi, ariko bishobora no kuba birimo gusana ecran yangiritse cyangwa gusimbuza umukingo wo gusharija wangiritse. Gutunganya neza ni bwo buryo bugezweho cyane, hakoreshejwe amakuru yakozwe na charger kugira ngo hamenyekane ko byangiritse. Mu kugenzura ubushyuhe bw’imbere bwa module y’amashanyarazi ugereranyije n’umutwaro wayo, porogaramu ishobora guhanura ko umufana azananirwa cyangwa capacitor yangiritse. Ibi bituma hashobora gusimburwa mu gihe cyo gusura ahantu hateganyijwe, birinda ibura ry’amashanyarazi ritari ryateganyijwe ndetse n’igihombo cy’amafaranga yinjira n’icyizere cy’abakiriya.

Igice cya 11: Iyubahirizwa ry'amategeko, amahame ngenderwaho, n'ibyemeza mu gihe kizaza ku bijyanye no gushyuza Megawatt

Gukoresha amabwiriza mpuzamahanga n'amategeko yo mu gace ni kimwe mu bintu bigoye cyane mu guhitamo icyuma gishyushya cya DC cya 150kW. Kubahiriza amategeko si umutekano gusa; ahubwo ni ukwishyira hamwe no kurinda amategeko. Muri Amerika ya Ruguru, icyemezo cya UL (Underwriters Laboratories) ni cyo gipimo cya zahabu, cyane cyane UL 2202 ku bikoresho byo gusharija bya DC na UL 2231 ku buryo bwo kurinda abakozi. Mu Burayi no mu tundi turere twinshi, gushyira ikimenyetso cya CE no kubahiriza amabwiriza ya IEC 61851 na IEC 62196 ni itegeko.

Uretse umutekano w’ibanze w’amashanyarazi, abaguzi bagomba kuzirikana amahame ngenderwaho y’ibipimo. Mu turere twinshi, nko mu Budage bufite itegeko rya "Eichrecht", icyuma gipima ingufu kiri muri sharija kigomba kuba cyemewe n’amategeko kandi kigaragara ku muguzi, kikareba ko yishyuzwa neza ibyo ahabwa. Uko ibihugu byinshi bikurikiza amategeko asa n’ayo yo kurengera abaguzi, guhitamo sharija ifite icyuma gipima DC cyemewe mbere kandi gifite ubuziranenge ni intambwe ikomeye mu kurinda ishoramari ryawe mu gihe kizaza. Byongeye kandi, umutekano w’ikoranabuhanga uri kuba ikintu cy’ingenzi mu mategeko. Sharija ni ahantu ho kwinjira muri grid na network y’abatanga serivisi; zigomba gushyira mu bikorwa uburyo bwo gushakisha amakuru (TLS 1.2 cyangwa irenga), uburyo bwo gutangiza amakuru neza, no kwirinda amakosa asanzwe mu kurinda amakuru kugira ngo birinde ubujura n’ihohoterwa rishingiye ku makuru.

Guteza imbere ejo hazaza bivuze kandi kureba imbere y'ikinyejana gitaha cy'ikoranabuhanga rya EV. Nubwo 150kW ari "yihuta", inganda zisanzwe zerekeza kuri 350kW ndetse na Megawatt Charging Systems (MCS) ku makamyo aremereye. Umuguzi utekereza ku gihe azahitamo urubuga rwa 150kW "rushobora kuvugururwa." Ibi bishobora gusobanura akabati gafite imyanya irimo modules nyinshi z'amashanyarazi, cyangwa sisitemu yagenewe "guhuza ibintu bingana," aho ibice bibiri bya 150kW bishobora guhuzwa kugira ngo bigeze kuri 300kW ku modoka imwe nibiba ngombwa. Byongeye kandi, inkunga ya ISO 15118-20 (version iheruka y'urwego rw'itumanaho) izakenerwa kugira ngo habeho ibintu bigezweho nko gushyushya ibintu mu cyerekezo kimwe (V2G/V2H) no guhuza grid mu buryo bugezweho.

Ikindi kintu cyo kubungabunga ibidukikije mu gihe kizaza ni ukubungabunga ibidukikije. Ibikoresho bikoreshwa mu kubaka icyuma gishyushya umuriro—aluminium ishobora kongera gukoreshwa ugereranyije n'icyuma gishushanyijeho irangi, ubwoko bw'icyuma gishyushya umuriro gikoreshwa mu buryo bw'amazi—bizarushaho kugira ingaruka ku byangombwa bya sitasiyo “by'icyatsi kibisi”. Bamwe mu bakoresha basanzwe bashyiramo imirasire y'izuba hejuru y'icyuma gishyushya umuriro cya 150kW. Ibi ntibitanga gusa igicucu n'uburinzi bw'imvura ku bakoresha ahubwo binatanga ingufu zisukuye zishobora gushyirwa muri DC bus y'icyuma gishyushya umuriro, bikagabanya igihombo cyo gutwara no kunoza imikorere y'aho hantu.
