Pambuyo pazaka pafupifupi 15 zachitukuko, magalimoto amagetsi atsopano apanga ma depositi ena aukadaulo. Kusankhidwa kwapre-charging resistoramatsimikizira liwiro la galimoto isanakwane nthawi yolipirira, kukula kwa danga lomwe limakhala ndi kukana kwapang'onopang'ono, chitetezo chamagetsi chamagetsi chagalimoto, kudalirika komanso kukhazikika.
Pre-charge resistance ili m'galimoto yamagetsi yamagetsi pa capacitor kumayambiriro kwa pang'onopang'onocharger choletsa, ngati palibe chotsutsa chisanachitike, chowongolera chidzakhala chachikulu kwambiri kuti chiswe capacitor. Mphamvu yamagetsi yamagetsi yomwe imawonjezedwa mwachindunji ku capacitor, yofanana ndi nthawi yofupikitsa, yomwe imakhala yochepa kwambiri imatha kuwononga zida zamagetsi zamagetsi. Chifukwa chake, popanga dera, kukana kolipiritsa kuyenera kuganiziridwa kuti zitsimikizire chitetezo cha dera.
Pali malo awiri mu dera lapamwamba-voltage ya galimoto yamagetsi kumenepre-charge resistoramagwiritsidwa ntchito, omwe ndi owongolera ma motor pre-charge circuit ndi high-voltage accessory pre-charge circuit. The motor controller (inverter circuit) ili ndi capacitor yaikulu, yomwe imayenera kulipira kale kuti iwononge mphamvu ya capacitor.
Malinga ndi kutsimikizika kwenikweni kwapangidwe komwe kunapezeka: ceramic resistor ndiyothandiza kwambiri pochapira, kutulutsa ndi zina zofunika. Lili ndi kutentha kwapadera kwapadera ndipo limatha kuyamwa mphamvu zambiri panthawi yolipiritsa mu nthawi yochepa.
