Pain point mukushambadzira kwemota nyowani dzesimba dzichiripo, uye DC inokurumidza kuchaja mirwi inogona kusangana nezvinodiwa zvekukurumidza kuzadza simba. Kuzivikanwa kwemotokari nyowani dzesimba kunodzivirirwa nepakati marwadzo mapoinzi senge hupenyu hwebhatiri uye kuchaja kushushikana. Mukupindura matambudziko ari pamusoro apa, vagadziri vakuru vari kuenderera mberi nekugadzira tekinoroji yebhatiri uye vari kupindura kunetseka kwemusika nekuisa mamwe mabhatiri. Zvisinei, sezvo zvakaoma kuwana mabhindauko makuru etekinoroji mukuita kwemabhatiri emagetsi munguva pfupi, zvakaoma kuwana kuwedzera kwakakosha kwemamaira pachaji imwe nekukurumidza. Kunyangwe kuisa mabhatiri ekuwedzera kunogona kugadzirisa dambudziko rekusagadzikana kwevamwe vatengi munguva pfupi, mhedzisiro yaro ndeyekuwedzera kwekuchaja nguva. Nguva yekuchaja inoenderana nekuwanda kwebhatiri uye simba rekuchaja. Kukura kwebhatiri, ndiko kukwira kwenzvimbo yekufamba, uye nguva yekuchaja inodiwa pasina kuwedzera simba rekuchaja. Zvichienzaniswa ne AC piles, DC inokurumidza kuchaja mirwi inogona kuchaja bhatiri nekukurumidza, nekudaro ichidzikisa nguva yekuchaja, kuvandudza kunyatsochaja, uye kusangana nezvinodiwa nevaridzi vemotokari kukurumidza kuzadza simba.
Nemaitiro eDC anokurumidza kuchaja zviteshi achitsiva AC inononoka kuchaja zviteshi, OBC yave iyo huru pakati pemakambani emotokari. Parizvino, kune nzira mbiri dzekutengesa motokari dzemagetsi: imwe iri kuburikidza ne "fast charge" port, iyo inoshandisa DC murwi kuti iite zvakananga bhatiri remagetsi; imwe iri kuburikidza ne AC yekuchaja port, iyo "slow charge" port, iyo inoda motokari Mushure mokunge OBC yemukati ichiita transformer nekugadzirisa, inobuda kutengesa motokari yemagetsi. Nekudaro, sezvo DC inokurumidza kuchaja mirwi zvishoma nezvishoma inotsiva AC inononoka kuchaja mirwi, mamwe makambani emota zvishoma nezvishoma ari kuyedza kukanzura AC yekuchaja chiteshi. Semuenzaniso, NIO ET7 yakadzima AC yekuchaja chiteshi, ichisiya imwe chete DC yekuchaja chiteshi uye yakananga kusiya OBC. Kubvisa OBC kunogona kuderedza huremu hwemotokari uye kuderedza mutengo wemotokari dzemagetsi. Maitiro ekukanzura AC yekuchaja madoko haangodzikisire huremu hwemotokari, asi zvakare kuderedza mitengo yakavanzika senge mota yekuongorora malink, bvunzo kutenderera, uye modhi yekudyara mari, izvo zvinogona kudzikisa mutengo wekutengesa wemotokari dzemagetsi. Pamusoro pezvo, sezvo mutengo wekugadzirisa weOBC wakakwira zvakanyanya pane wekunze DC yekuchaja mirwi, kukanzura OBC kunozoderedza mutengo wevatengi unotevera wemotokari.
Parizvino kune nzira mbiri dzepamusoro-simba nekukurumidza kuchaja tekinoroji: yakakwira-ikozvino inokurumidza kuchaja uye yakakwirira-voltage inokurumidza kuchaja. Mukupindura kumatambudziko akadai seasina kukwana ekuchaja zvivakwa uye inononoka kuchaja kumhanya, iyo huru yehunyanzvi mhinduro muindastiri ndeye yakakwirira-simba DC inokurumidza kuchaja. Parizvino, mota uye mirwi yakawana yakakura, uye simba reiyo iripo DC yekukurumidza kuchaja modhi inowanzoita 60-120KW. Kuti uwedzere kupfupisa nguva yekuchaja, kune nzira mbiri dzekuvandudza mune ramangwana. Imwe ndeyepamusoro-ikozvino DC inokurumidza kuchaja, uye imwe iri High voltage DC ichikurumidza kuchaja. Nheyo ndeyekuwedzera kuwedzera simba rekuchaja nekuwedzera ikozvino kana kuwedzera voltage.
Iko kuoma kweiyo yepamusoro-ikozvino yekuchaja tekinoroji iri mukupisa kwayo kwakanyanya kudiwa. Tesla ikambani inomiririra yepamusoro-ikozvino DC inokurumidza kuchaja mhinduro. Nekuda kweiyo immature high-voltage supply chain mukutanga, Tesla akasarudza kuchengetedza mota yevoltage platform isina kuchinjwa uye kushandisa high-current DC kuti iwane kukurumidza kuchaja. Tesla's V3 supercharger ine yakanyanya kubuda ikozvino inoda kusvika 520A uye yakanyanya kuchaja simba re250kW. Nekudaro, iyo yakashata yeakakwira-ikozvino inokurumidza kuchaja tekinoroji ndeyekuti inogona chete kuwana yakanyanya kuchaja simba pasi pe10-30% SOC mamiriro. Paunenge uchichaja pa30-90% SOC, uchienzaniswa neTesla V2 yekuchaja murwi (yakanyanya kubuda ikozvino 330A, yakanyanya simba 150kW), zvakanakira hazvisi pachena. Pamusoro pezvo, tekinoroji yepamusoro-yazvino haisati yakwanisa kuzadzisa zvinodiwa zve4C kuchaja. Kuti uwane 4C kuchaja, yakakwira-voltage architecture ichiri kuda kugamuchirwa. Sezvo chigadzirwa chacho chinokonzera kupisa kwakawanda panguva yekuchaja kwepamusoro-soro, nekuda kwekuchengetedzwa kwebheteri kufunga, mukati mayo magadzirirwo uye teknolojia inoda zvakanyanya kupisa kupisa, izvo zvinozoitawo kuwedzera kusingadzivisiki kwemari.
