-Uma ufuna ukushaja okusheshayo kwemoto yakho kagesi, awukwazi ukungahambi kahle ngobuchwepheshe be-high-voltage, bamanje obuphezulu bokushaja izinqwaba

Ubuchwepheshe obuphezulu bamanje nobuphezulu be-voltage

Njengoba ububanzi bukhula kancane kancane, kunezinselele ezifana nokunciphisa isikhathi sokushaja nokunciphisa izindleko zobunikazi, futhi umsebenzi wokuqala uwukuthuthukisa usayizi wemojuli ukuze kuzuzwe ukuthuthukiswa kwamandla. Kusukela amandla weinqwaba yokushajaikakhulukazi kuncike ekuphakameni kwamandla emojula yokushaja, futhi kunqunyelwe umthamo womkhiqizo, indawo yaphansi kanye nezindleko zokukhiqiza, ukumane ukwandise inani lamamojula akusesona isisombululo esingcono kakhulu. Ngakho-ke, indlela yokwandisa amandla emojula eyodwa ngaphandle kokwengeza ivolumu eyengeziwe sekuyinkinga yezobuchwepheshe ukuthiukushaja abakhiqizi bemojulaisidingo sokunqoba ngokuphuthumayo.

Imishini yokushaja ye-DCifinyelela ikhono elihle lokushaja elisheshayo ngobuchwepheshe bamanje kanye nobuchwepheshe bamandla kagesi aphezulu. Ngokunyuka kancane kancane kwamandla kagesi namandla, lokhu kubeka phambili izidingo eziqinile zokusebenza okuzinzile, ukuchithwa kokushisa okuphumelelayo nokusebenza kahle kokuguqulwa kwemojula yokushaja, ngokungangabazeki okusetha izinselele zobuchwepheshe eziphakeme kubakhiqizi bamamojula wokushaja.

Lapho bebhekene nesidingo semakethe sokushaja okusheshayo kwamandla, abakhiqizi bamamojula ashajayo badinga ukuqhubeka basungule futhi bathuthukise ubuchwepheshe obuyisisekelo futhi bazakhele imigoqo yabo yobuchwepheshe ewumongo. Lokhu kuzoba ukhiye emqhudelwaneni wezimakethe wesikhathi esizayo, kuphela ngokuba yingcweti kobuchwepheshe obuyisisekelo, ukuze unganqotshwa emqhudelwaneni oshubile wezimakethe.

I-1) Umzila wamanje: izinga lokukhushulwa liphansi, futhi izidingo zokuphatha ezishisayo ziphezulu. Ngokomthetho kaJoule (ifomula Q = I2Rt), ukwanda kwamanje kuzokwandisa kakhulu ukushisa ngesikhathi sokushaja, okunezidingo eziphakeme zokuqeda ukushisa, njengesixazululo sokushaja esisheshayo se-Tesla, inqwaba yayo ye-V3 supercharging inenani eliphezulu lokusebenza lamanje elingaphezu kuka-600A, okudinga ukushuba kwezintambo zezintambo ngesikhathi esifanayo, i-dissipa ine-harness ephezulu yezintambo ngesikhathi esifanayo, futhi ingakwazi ukufeza kuphela i-wiring harness ngesikhathi esifanayo, futhi ngesikhathi esifanayo ikwazi ukufeza i-wiring harness. amandla amakhulu okushaja angu-250kW ku-5% -27% SOC, futhi ukushaja okuphumelelayo akukhaviwe ngokugcwele. Njengamanje, abakhiqizi bezimoto ezifuywayo abazange benze izinguquko ezinkulu ezenziwe ngokwezifiso ohlelweni lokukhipha ukushisa, futhiizinqwaba zokushaja zamanjeukuthembela kakhulu ezinhlelweni zokuzakhela, okuholela ezindlekweni eziphezulu zokuphromotha.

2) Umzila wamandla kagesi aphezulu: Kuyimodi evame ukusetshenziswa abakhiqizi bezimoto, abangacabangela izinzuzo zokunciphisa ukusetshenziswa kwamandla, ukuthuthukisa impilo yebhethri, ukunciphisa isisindo, nokonga isikhala. Njengamanje, elinganiselwe amandla kagesi okumelana namadivayisi kagesi e-IGBT asekelwe ku-silicon, isixazululo sokushaja okusheshayo esivame ukwamukelwa izinkampani zezimoto isiteji se-voltage engu-400V, okungukuthi, amandla okushaja angu-100kW angafinyelelwa nge-current engu-250A (amandla angu-100kW angashajwa ngebanga elingu-10km cishe imizuzu eyi-100). Kusukela kwethulwa iplathifomu ye-Porsche engu-800V yamandla kagesi aphezulu (ethola amandla angu-300KW nokunciphisa izintambo zezintambo ezinamandla kagesi ngohhafu), izinkampani ezinkulu zezimoto seziqalile ukucwaninga nokuhlela iplathifomu engu-800V yamandla kagesi aphezulu. Uma kuqhathaniswa neplathifomu engu-400V, inkundla yamandla kagesi angu-800V ine-current encane yokusebenza, egcina ivolumu yehhanisi lezintambo, inciphisa ukulahlekelwa kokumelana kwangaphakathi kwesekethe, futhi ithuthukise ukuminyana kwamandla nokusebenza kahle kwamandla ekucashile.

Njengamanje, uhla lwamandla kagesi ophuma njalo lwemojula engu-40kW eyinhloko embonini luyi-300Vdc~1000Vdc, oluhambisana nezidingo zokushaja zezimoto zamanje zamanje zabagibeli zepulatifomu engu-400V, amabhasi angu-750V kanye nezimoto zepulatifomu zamandla aphezulu angu-800V-1000V zesikhathi esizayo; Ibanga lamandla kagesi okukhiphayo wemojula engu-40kW ye-Infineon, iTelai neShenghong ingafinyelela ku-50Vdc~1000Vdc, kucatshangelwa izidingo zokushajwa kwezimoto ezinamandla kagesi aphansi. Mayelana nokusebenza kahle kwemojuli iyonke, amamojula angu-40kW asebenza kahle kakhuluI-BeiHai Powersebenzisa amadivayisi kagesi e-SIC, futhi ukusebenza kahle okuphezulu kungafinyelela ku-97%, okungaphezulu kwesilinganiso semboni.
