–Uma ufuna ukushaja okusheshayo kwemoto yakho kagesi, awukwazi ukwenza iphutha ngobuchwepheshe obunamandla aphezulu, obusebenzisa amandla aphezulu okushaja ama-piles.

Ubuchwepheshe bamandla aphezulu kanye nobe-voltage ephezulu

Njengoba ububanzi bukhula kancane kancane, kunezinselele ezifana nokunciphisa isikhathi sokushaja nokunciphisa izindleko zobunikazi, futhi umsebenzi wokuqala ukwenza ngcono usayizi wemojuli ukuze kufezwe ukuthuthukiswa kwamandla. Njengoba amandla e-inqwaba yokushajaikakhulukazi kuncike ekubekweni kwamandla kwemodyuli yokushaja, futhi kunqunyelwe yivolumu yomkhiqizo, isikhala sephansi kanye nezindleko zokukhiqiza, ukukhulisa inani lamamojula akuseyona ikhambi elingcono kakhulu. Ngakho-ke, indlela yokwandisa amandla emodyuli eyodwa ngaphandle kokwengeza ivolumu eyengeziwe isibe yinkinga yobuchwepheshe ebangela lokho.abakhiqizi bemodyuli yokushajaisidingo sokunqoba ngokushesha.

Imishini yokushaja ye-DCifinyelela ikhono elihle kakhulu lokushaja okusheshayo ngokusebenzisa ubuchwepheshe bamandla aphezulu kanye nobuchwepheshe bamandla aphezulu. Ngokukhula kancane kancane kwe-voltage namandla, lokhu kubeka phambili izidingo eziqinile zokusebenza okuzinzile, ukushabalalisa ukushisa okuphumelelayo kanye nokusebenza kahle kokuguqulwa kwemojuli yokushaja, okungangabazeki ukuthi kubeka izinselele zobuchwepheshe eziphezulu kubakhiqizi bamamojuli okushaja.

Njengoba bebhekene nesidingo semakethe sokushaja okusheshayo okunamandla aphezulu, abakhiqizi bemojula yokushaja badinga ukuqhubeka nokuthuthukisa ubuchwepheshe obuyisisekelo futhi bakhe izithiyo zabo zobuchwepheshe eziyinhloko. Lokhu kuzoba yisihluthulelo somncintiswano wemakethe wesikhathi esizayo, kuphela ngokuqonda ubuchwepheshe obuyinhloko, ukuze bangabi nakwehlulwa emncintiswaneni wemakethe onamandla.

1) Indlela yamandla aphezulu: izinga lokukhushulwa liphansi, futhi izidingo zokuphathwa kokushisa ziphakeme. Ngokomthetho kaJoule (ifomula Q=I2Rt), ukwanda kwamandla kagesi kuzokwandisa kakhulu ukushisa ngesikhathi sokushaja, okunezidingo eziphezulu zokushaja ukushisa, njengesixazululo sokushaja okusheshayo sikaTesla samandla aphezulu, esinenqwaba ye-V3 supercharging enomthamo wokusebenza ophezulu ongaphezu kuka-600A, odinga i-wiring harness ejiyile, futhi ngesikhathi esifanayo, inezidingo eziphakeme zobuchwepheshe bokushaja ukushisa, futhi ingafinyelela kuphela amandla aphezulu okushaja angu-250kW ku-5%-27% SOC, futhi ukushaja okusebenzayo akumboziwe ngokuphelele. Okwamanje, abakhiqizi bezimoto zasekhaya abakenzi izinguquko ezibalulekile ezenziwe ngokwezifiso ohlelweni lokushaja ukushisa, futhiizinqwaba zokushaja zamandla aphezulubathembele kakhulu ezinhlelweni ezakhelwe zona, okuholela ezindleleni eziphezulu zokukhushulwa.

2) Indlela enamandla kagesi: Kuyindlela evame ukusetshenziswa abakhiqizi bezimoto, engacabangela izinzuzo zokunciphisa ukusetshenziswa kwamandla, ukuthuthukisa impilo yebhethri, ukunciphisa isisindo, nokonga isikhala. Njengamanje, inqunyelwe amandla e-stander voltage amadivayisi kagesi e-IGBT asekelwe ku-silicon, ikhambi lokushaja okusheshayo elivame ukwamukelwa yizinkampani zezimoto yipulatifomu enamandla kagesi angu-400V, okungukuthi, amandla okushaja angu-100kW angatholakala ngogesi ongu-250A (amandla angu-100kW angashajwa imizuzu eyi-10 cishe amakhilomitha ayi-100). Kusukela kwethulwa ipulatifomu enamandla kagesi angu-800V kaPorsche (efinyelela amandla angu-300KW futhi inciphise i-wiring harness enamandla kagesi), izinkampani ezinkulu zezimoto ziqale ukucwaninga nokubeka ipulatifomu enamandla kagesi angu-800V. Uma kuqhathaniswa nepulatifomu engu-400V, ipulatifomu yamandla kagesi angu-800V inogesi omncane osebenzayo, okusindisa ivolumu ye-wiring harness, kunciphisa ukulahlekelwa kokumelana kwangaphakathi kwesekethe, futhi kuthuthukise ubuningi bamandla kanye nokusebenza kahle kwamandla okufihliwe.

Njengamanje, ububanzi bamandla okukhipha amandla obungaguquki bemojuli engu-40kW eyinhloko embonini buyi-300Vdc ~ 1000Vdc, okuhambisana nezidingo zokushaja zezimoto zabagibeli zepulatifomu yamanje engu-400V, amabhasi angu-750V kanye nezimoto zepulatifomu ye-800V-1000V yesikhathi esizayo; Ububanzi bamandla okukhipha bemojuli engu-40kW ye-Infineon, i-Telai kanye ne-Shenghong bungafinyelela ku-50Vdc ~ 1000Vdc, kucatshangelwa izidingo zokushaja zezimoto ze-voltage ephansi. Ngokuphathelene nokusebenza kahle kwemojuli iyonke, amamojuli e-40kW aphezulu okusebenza kahleI-BeiHai Powersebenzisa amadivayisi kagesi e-SIC, futhi ukusebenza kahle okuphezulu kungafinyelela ku-97%, okuphakeme kunesilinganiso semboni.
