Zowawa pakugulitsa magalimoto amagetsi atsopano zikadalipo, ndipo milu yothamangitsa ya DC imatha kukwaniritsa kufunikira kowonjezeranso mphamvu mwachangu. Kutchuka kwa magalimoto amphamvu zatsopano kumangongoleredwa ndi zowawa zazikulu monga moyo wa batri komanso nkhawa yolipira. Poyankha mavuto omwe ali pamwambawa, opanga akuluakulu akupitirizabe kupanga teknoloji ya batri ndipo akuyankha nkhawa za msika poika mabatire owonjezera. Komabe, popeza ndizovuta kukwaniritsa zopambana zaukadaulo pakugwirira ntchito kwa mabatire amagetsi kwakanthawi kochepa, ndizovuta kuti tikwaniritse kuchuluka kwa mtunda pamtengo umodzi mwachangu. Ngakhale kuyika mabatire owonjezera kumatha kuthana ndi vuto lanthawi yayitali la ogula kwakanthawi kochepa, zotsatira zake ndikuwonjezera nthawi yolipira. Nthawi yolipira imagwirizana ndi kuchuluka kwa batri ndi mphamvu yopangira. Kuchuluka kwa batire, kumapangitsanso kuchuluka kwa maulendo apaulendo, komanso nthawi yayitali yolipiritsa imafunika popanda kuwonjezera mphamvu yotsatsira. Poyerekeza ndi milu ya AC, milu yothamangitsa ya DC imatha kulipiritsa batire mwachangu, potero kuchepetsa nthawi yolipiritsa, kuwongolera kuyendetsa bwino, ndikukwaniritsa zosowa za eni magalimoto kuti awonjezere mphamvu mwachangu.
Ndi kachitidwe ka ma station othamangitsira a DC omwe alowa m'malo mwa ma AC omwe amachapira pang'onopang'ono, OBC yakhala yodziwika bwino pakati pamakampani amagalimoto. Pakalipano, pali njira ziwiri zoyendetsera magalimoto amagetsi: imodzi imadutsa pa doko la "fast charge", lomwe limagwiritsa ntchito mulu wa DC kuti lipereke mwachindunji batire la mphamvu; chinacho chikudutsa pa doko la AC chojambulira, chomwe ndi "chapang'onopang'ono" doko, chomwe chimafuna galimoto Pambuyo pa OBC yamkati imapanga transformer ndi kukonzanso, imatuluka kulipira galimoto yamagetsi. Komabe, pomwe milu yothamangitsa ya DC imalowetsa pang'onopang'ono milu yothamangitsa ya AC, makampani ena amagalimoto pang'onopang'ono akuyesera kuletsa doko la AC. Mwachitsanzo, NIO ET7 yaletsa doko lolipiritsa la AC, kusiya doko limodzi lokha la DC ndikusiya mwachindunji OBC. Kuchotsa OBC kungachepetse kulemera kwa galimoto ndikuchepetsa mtengo wa magalimoto amagetsi. Mchitidwe woletsa madoko opangira ma AC sikungochepetsa kulemera kwa galimoto, komanso kuchepetsa ndalama zobisika monga maulalo oyesa magalimoto, maulendo oyeserera, ndi mabizinesi achitukuko chachitsanzo, zomwe zingachepetsenso mtengo wogulitsa magalimoto amagetsi. Kuphatikiza apo, popeza mitengo yokonza OBC ndiyokwera kwambiri kuposa milu yolipiritsa yakunja ya DC, kuletsa OBC kudzachepetsa mtengo wa ogula wogwiritsa ntchito galimoto.
Pakali pano pali njira ziwiri zopangira ukadaulo wamagetsi othamanga kwambiri: kuthamangitsa kwanthawi yayitali komanso kuthamangitsa kwamphamvu kwambiri. Pothana ndi zovuta monga zopangira zopangira zopanda ungwiro komanso kuthamanga kwapang'onopang'ono, njira yaukadaulo yodziwika bwino pamsika ndikuyitanitsa mwachangu kwa DC. Pakalipano, magalimoto onse ndi milu yapindula kwambiri, ndipo mphamvu ya DC yothamanga mofulumira imakhala 60-120KW. Kuti mufupikitse nthawi yolipira, pali njira ziwiri zachitukuko m'tsogolomu. Imodzi ndi yothamanga kwambiri pakali pano ya DC, ndipo ina ndi High voltage DC yothamanga mofulumira. Mfundoyi ndikuwonjezeranso mphamvu yolipiritsa powonjezera magetsi kapena kuonjezera magetsi.
Kuvuta kwaukadaulo wamakono wothamangitsa mwachangu kwagona pakufunika kwake kwa kutentha kwambiri. Tesla ndi kampani yoyimilira mayankho othamangitsa mwachangu a DC. Chifukwa cha kusasinthika kwamagetsi apamwamba kwambiri koyambirira, Tesla adasankha kuti pulatifomu yamagetsi isasinthe ndikugwiritsa ntchito DC wamakono kuti azilipira mwachangu. Tesla's V3 supercharger ili ndi mphamvu yotulutsa pafupifupi 520A komanso mphamvu yopitilira 250kW. Komabe, kuipa kwaukadaulo wamakina othamanga kwambiri ndikuti chitha kungokwanitsa kuyitanitsa mphamvu zambiri pansi pa 10-30% SOC mikhalidwe. Mukalipira pa 30-90% SOC, poyerekeza ndi Tesla V2 nawuza mulu (pazipita linanena bungwe panopa 330A, pazipita mphamvu 150kW), ubwino si zoonekeratu. Kuphatikiza apo, luso lamakono lamakono silingathe kukwaniritsa zosowa za 4C kulipiritsa. Kuti mukwaniritse kuyitanitsa kwa 4C, kamangidwe kamphamvu kwambiri kakufunikabe kukhazikitsidwa. Popeza kuti mankhwalawa amapanga kutentha kwakukulu panthawi yothamanga kwambiri, chifukwa cha kuganiziridwa kwa chitetezo cha batri, mapangidwe ake amkati ndi teknoloji zimafuna kutentha kwakukulu kwambiri, zomwe zidzachititsanso kuti ndalama ziwonjezeke.
