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 yokuchasa kwangaphambili kumisela isantya sexesha lokutshaja kwangaphambili kwesithuthi, ubungakanani besithuba esithathwe yi-resistor precharge, 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.
