Emva kweminyaka eyi-10 yophuhliso, iimoto zombane zamandla amatsha zenze iidiphozithi zobugcisa.Uyilo lwamalungu esithuthi sombane kunye namacandelo anolwazi oluninzi, phakathi kwawo ukuyilaisixhasi sokutshaja kwangaphambilikwisekethe yangaphambi kokutshaja kufuneka iqwalasele iimeko ezininzi kunye neemeko zokusebenza.Ukukhethwa kwe-resistor precharge inquma isantya sexesha lokutshaja kwangaphambili kwesithuthi, ubungakanani besithuba esithathwe yi-resistor yokuchasa, ukhuseleko lombane ophezulu wesithuthi, ukuthembeka kunye nokuzinza.
Isixhasi sokuchasa kwangaphambilii-resistor ehlawulisa ngokukhawuleza i-capacitor kwinqanaba lokuqala le-high-voltage power-up yesithuthi, ukuba akukho mxhasi wangaphambili wokutshaja, umjelo wokutshaja uya kuba mkhulu kakhulu ukuphula i-capacitor.Amandla aphezulu ombane afakwe ngokuthe ngqo kwi-capacitor, elingana ne-short-circuit ngokukhawuleza, i-short-circuit current egqithisileyo iya kulimaza amacandelo ombane aphezulu.Ngoko ke, xa uyila isiphaluka, i-resistor precharge kufuneka ithathelwe ingqalelo ukuze kuqinisekiswe ukhuseleko lwesiphaluka.
Kukho iindawo ezimbini kwisekethe ye-high-voltage yesithuthi sombane aphoisixhasi sokutshaja kwangaphambilikusetyenziswa, oko kukuthi isilawuli semotor precharge circuit kunye ne-high-voltage accessory pre-charging circuit.Umlawuli we-motor (inverter circuit) une-capacitor enkulu, ekufuneka ihlawulwe kwangaphambili ukulawula i-capacitor yokutshaja okwangoku.Izincedisi eziphezulu ze-voltage ngokubanzi nazo zine-DCDC (i-DC converter), i-OBC (itshaja ekwibhodi), i-PDU (ibhokisi yokuhambisa i-voltage ephezulu), impompo yamafutha, impompo yamanzi, i-AC (icompressor yomoya) kunye nezinye iindawo, kuya kubakho. i-capacitance enkulu ngaphakathi kweengxenye, ngoko kufuneka zihlawulwe kwangaphambili.
