Iindawo ezibangela intlungu ekuthengisweni kwezithuthi ezintsha zamandla zisekho, kwaye ii-DC fast charging piles zinokuhlangabezana nemfuno yokuphinda kusetyenziswe amandla ngokukhawuleza. Ukuthandwa kwezithuthi ezintsha zamandla kuthintelwe ziimeko eziphambili zentlungu ezifana nobomi bebhetri kunye nokukhathazeka ngokutshaja. Ukuphendula ezi ngxaki zingasentla, abavelisi abakhulu bayaqhubeka nokuphuhlisa iteknoloji yebhetri kwaye basabela kukukhathazeka kwemarike ngokufaka iibhetri ezongezelelweyo. Nangona kunjalo, ekubeni kunzima ukufikelela kwimpumelelo enkulu yetekhnoloji ekusebenzeni kweebhetri zamandla kwixesha elifutshane, kunzima ukufikelela ekwandeni okukhulu kwimayile kwitshaja enye ngokukhawuleza. Nangona ukufaka iibhetri ezongezelelweyo kunokusombulula ingxaki yokukhathazeka yoluhlu lwabanye abathengi kwixesha elifutshane, isiphumo sayo esibi kukunyuka kwexesha lokutshaja. Ixesha lokutshaja linxulumene nomthamo webhetri kunye namandla okutshaja. Okukhona umthamo webhetri mkhulu, kokukhona uluhlu lokuhamba ngenqanawa luphezulu, kwaye kokukhona ixesha lokutshaja lifuneka ixesha elide ngaphandle kokunyusa amandla okutshaja. Xa kuthelekiswa nee-AC piles, ii-DC fast charging piles zinokutshaja ibhetri ngokukhawuleza, ngaloo ndlela zinciphisa ixesha lokutshaja, ziphucule ukusebenza kakuhle kokutshaja, kwaye zihlangabezane neemfuno zabanini beemoto zokuphinda kusetyenziswe amandla ngokukhawuleza.
Njengoko izikhululo zokutshaja ngokukhawuleza ze-DC zithatha indawo yezikhululo zokutshaja kancinci ze-AC, i-OBC iye yaba yeyona nto iphambili phakathi kweenkampani zeemoto. Okwangoku, kukho iindlela ezimbini zokutshaja izithuthi zombane: enye idlula kwizibuko "elitshaja ngokukhawuleza", elisebenzisa inqwaba ye-DC ukutshaja ngqo ibhetri yamandla; enye idlula kwizibuko "elitshaja kancinci", elifuna imoto. Emva kokuba i-OBC yangaphakathi yenze i-transformer kunye nokulungiswa, iphuma ekutshajiseni imoto yombane. Nangona kunjalo, njengoko iinqwaba zokutshaja ngokukhawuleza ze-DC zithatha indawo yeenqwaba zokutshaja kancinci ze-AC, ezinye iinkampani zeemoto zizama kancinci ukurhoxisa izibuko lokutshaja ze-AC. Umzekelo, i-NIO ET7 iyirhoxisile izibuko lokutshaja ze-AC, ishiya izibuko elinye kuphela lokutshaja ze-DC kwaye ishiya ngokuthe ngqo i-OBC. Ukususa i-OBC kunokunciphisa ubunzima bezithuthi kwaye kunciphise iindleko zezithuthi zombane. Umkhwa wokurhoxisa iizibuko zokutshaja ze-AC awuyi kunciphisa ubunzima bezithuthi kuphela, kodwa uya kunciphisa neendleko ezifihlakeleyo ezifana neekhonkco zovavanyo lwezithuthi, imijikelo yovavanyo, kunye notyalo-mali lophuhliso lweemodeli, olunokunciphisa ngakumbi ixabiso lokuthengisa lezithuthi zombane. Ukongeza, ekubeni ixabiso lokulungisa i-OBC liphezulu kakhulu kuneleepali zokutshaja ze-DC zangaphandle, ukurhoxisa i-OBC kuya kunciphisa phantse iindleko zokusebenzisa imoto zabathengi emva koko.
Okwangoku kukho iindlela ezimbini zobuchwepheshe bokutshaja ngokukhawuleza obunamandla aphezulu: ukutshaja ngokukhawuleza okunamandla aphezulu kunye nokutshaja ngokukhawuleza okunamandla aphezulu. Ukuphendula iingxaki ezifana neziseko zokutshaja ezingaphelelanga kunye nesantya sokutshaja esicothayo, isisombululo sobugcisa esiphambili kushishino kukutshaja ngokukhawuleza okunamandla aphezulu e-DC. Okwangoku, zombini izithuthi kunye neenqwaba zifikelele kwinqanaba elikhulu, kwaye amandla emo yokutshaja ngokukhawuleza ye-DC ekhoyo ngokubanzi yi-60-120KW. Ukuze kuncitshiswe ixesha lokutshaja, kukho iindlela ezimbini zophuhliso kwixesha elizayo. Enye kukutshaja ngokukhawuleza okunamandla aphezulu e-DC, kwaye enye kukutshaja ngokukhawuleza okunamandla aphezulu e-DC. Umgaqo kukunyusa amandla okutshaja ngokunyusa amandla okutshaja okanye ukwandisa amandla okutshaja.
Ubunzima bobuchwepheshe bokutshaja ngokukhawuleza obunamandla aphezulu buxhomekeke kwiimfuno zayo zokusasaza ubushushu obuphezulu. I-Tesla yinkampani emele izisombululo zokutshaja ngokukhawuleza ze-DC ezinombane ophezulu. Ngenxa yokuhanjiswa kwe-voltage ephezulu okungavuthwanga kwinqanaba lokuqala, i-Tesla ikhethe ukugcina iqonga le-voltage yesithuthi lingatshintshi kwaye isebenzise i-DC enombane ophezulu ukufezekisa ukutshaja ngokukhawuleza. I-V3 supercharger ye-Tesla inombane ophezulu ophumayo ophantse ube yi-520A kunye namandla aphezulu okutshaja angama-250kW. Nangona kunjalo, ingxaki yobuchwepheshe bokutshaja ngokukhawuleza obunamandla aphezulu kukuba inokufikelela kuphela ekutshajeni kwamandla aphezulu phantsi kweemeko ze-10-30% ze-SOC. Xa itshaja kwi-30-90% ye-SOC, xa ithelekiswa nenqwaba yokutshaja ye-Tesla V2 (umbane ophezulu ophumayo yi-330A, amandla aphezulu yi-150kW), izibonelelo azibonakali. Ukongeza, ubuchwepheshe obuphezulu abukwazi ukuhlangabezana neemfuno zokutshaja kwe-4C. Ukuze kufezekiswe ukutshaja kwe-4C, kusafuneka kusetyenziswe uyilo lwe-voltage ephezulu. Ekubeni imveliso ivelisa ubushushu obuninzi xa itshaja ngamandla aphezulu, ngenxa yokhuseleko lwebhetri, uyilo lwayo lwangaphakathi kunye netekhnoloji zifuna ukuchithwa kobushushu okuphezulu kakhulu, nto leyo eya kukhokelela ekonyukeni kweendleko okungenakuphepheka.
