Amaphuzu obuhlungu ekukhangiseni kwezimoto zamandla amasha asekhona, futhi izinqwaba zokushaja okusheshayo ze-DC zingahlangabezana nesidingo sokugcwaliswa kabusha kwamandla ngokushesha. Ukuduma kwezimoto zamandla amasha kukhawulelwe amaphuzu obuhlungu abalulekile njengempilo yebhethri nokukhathazeka kokushaja. Ukuphendula izinkinga ezingenhla, abakhiqizi abakhulu bayaqhubeka nokuthuthukisa ubuchwepheshe bebhethri futhi basabela ekukhathazekeni kwemakethe ngokufaka amabhethri engeziwe. Kodwa-ke, njengoba kunzima ukuzuza impumelelo enkulu yezobuchwepheshe ekusebenzeni kwamabhethri amandla esikhathini esifushane, kunzima ukuzuza ukukhuphuka okuphawulekayo kwemayela ngokushajwa okukodwa ngokushesha. Nakuba ukufaka amabhethri engeziwe kungaxazulula inkinga yokukhathazeka ebangeni labanye abathengi ngesikhathi esifushane, umphumela wawo oseceleni uwukwanda kwesikhathi sokushaja. Isikhathi sokushaja sihlobene nomthamo webhethri namandla okushaja. Uma umthamo webhethri umkhulu, ibanga lokuhamba liphezulu, futhi isikhathi sokushaja sidingeka ngaphandle kokwandisa amandla okushaja. Uma kuqhathaniswa nezinqwaba ze-AC, inqwaba yokushaja okusheshayo ye-DC ingashaja ibhethri ngokushesha, ngaleyo ndlela inciphise isikhathi sokushaja, ithuthukise ukusebenza kahle kokushaja, futhi ihlangabezane nezidingo zabanikazi bezimoto zokugcwalisa amandla ngokushesha.
Ngokuthambekela kweziteshi zokushaja okusheshayo ze-DC ezithatha indawo yeziteshi zokushaja ezihamba kancane ze-AC, i-OBC isiphenduke insakavukela ezinkampanini zezimoto. Njengamanje, kunezindlela ezimbili zokushaja izimoto zikagesi: eyodwa ngokusebenzisa imbobo "yokushaja okusheshayo", esebenzisa inqwaba ye-DC ukushaja ngokuqondile ibhethri lamandla; enye idlula imbobo yokushaja ye-AC, okuyichweba "lokushaja kancane", elidinga imoto Ngemuva kokuthi i-OBC yangaphakathi yenze i-transformer nokulungisa, iphuma ukushaja imoto kagesi. Kodwa-ke, njengoba izinqwaba zokushaja okusheshayo ze-DC kancane kancane zingena esikhundleni sezinqwaba zokushaja ezihamba kancane ze-AC, ezinye izinkampani zezimoto kancane kancane zizama ukukhansela imbobo yokushaja ye-AC. Isibonelo, i-NIO ET7 ikhansele imbobo yokushaja ye-AC, ishiya imbobo yokushaja eyodwa ye-DC futhi ishiya ngokuqondile i-OBC. Ukuqeda i-OBC kunganciphisa isisindo semoto futhi kunciphise izindleko zezimoto zikagesi. Ukuthambekela kokukhansela izimbobo zokushaja ze-AC ngeke kunciphise isisindo semoto kuphela, kodwa futhi kuzonciphisa izindleko ezifihliwe njengezixhumanisi zokuhlola imoto, imijikelezo yokuhlola, nokutshalwa kwezimali kokuthuthukiswa kwamamodeli, okungase kwehlise nakakhulu intengo yokuthengisa yezimoto zikagesi. Ngaphezu kwalokho, njengoba intengo yokunakekela ye-OBC iphezulu kakhulu kunaleyo yenqwaba yokushaja ye-DC yangaphandle, ukukhansela i-OBC kuzonciphisa izindleko zokusebenzisa imoto zabathengi.
Njengamanje kunezindlela ezimbili zobuchwepheshe bokushaja obusheshayo obunamandla amakhulu: ukushaja okusheshayo kwamanje kanye nokushaja okunamandla kagesi aphezulu. Ekuphenduleni izinkinga ezifana nengqalasizinda yokushaja engaphelele kanye nesivinini sokushaja esinensayo, isisombululo sobuchwepheshe esijwayelekile embonini ukushaja okusheshayo kwe-DC okunamandla amakhulu. Njengamanje, zombili izimoto kanye nenqwaba kuzuzwe ngezinga elikhulu, futhi amandla emodi etholakalayo yokushaja okusheshayo ye-DC ngokuvamile angu-60-120KW. Ukuze unciphise nakakhulu isikhathi sokushaja, kunezikhombisi-ndlela ezimbili zokuthuthukisa esikhathini esizayo. Enye ukushaja okusheshayo kwe-DC yamanje, kanti enye i-High voltage DC ukushaja okusheshayo. Isimiso siwukuqhubeka nokwandisa amandla okushaja ngokwandisa amandla amanje noma ukwandisa i-voltage.
Ubunzima bobuchwepheshe bokushaja okusheshayo bamanje busezimfuneko zabo zokulahla ukushisa okuphezulu. I-Tesla yinkampani emele izixazululo zokushaja okusheshayo ze-DC zamanje. Ngenxa yochungechunge lokunikezwa kwamandla kagesi ongavuthiwe ekuqaleni, u-Tesla wakhetha ukugcina isiteji samandla kagesi wemoto singashintshile futhi asebenzise i-DC yamanje ukuze afinyelele ukushaja okusheshayo. I-supercharger ye-V3 yakwaTesla inamandla okukhiphayo aphezulu acishe abe ngu-520A kanye namandla okushaja aphezulu angu-250kW. Kodwa-ke, okubi kobuchwepheshe bokushaja okusheshayo kwamanje ukuthi bungafinyelela kuphela ukushaja kwamandla aphezulu ngaphansi kwezimo ze-SOC ezingu-10-30%. Uma ishaja ku-30-90% SOC, uma kuqhathaniswa nenqwaba yokushaja ye-Tesla V2 (umthamo omkhulu wamanje ongu-330A, amandla aphezulu angu-150kW), izinzuzo azibonakali. Ngaphezu kwalokho, ubuchwepheshe bamanje abukwazi ukuhlangabezana nezidingo zokushaja kwe-4C. Ukuze uzuze ukushaja kwe-4C, i-architecture ene-voltage ephezulu isadinga ukwamukelwa. Njengoba umkhiqizo ukhiqiza ukushisa okukhulu ngesikhathi sokushaja okuphezulu, ngenxa yokucatshangelwa kokuphepha kwebhethri, ukuklama kwawo kwangaphakathi nobuchwepheshe kudinga ukuchithwa kokushisa okuphezulu kakhulu, okuzophinde kuholele ekwenyukeni kwezindleko okungenakugwemeka.
