Pambuyo pazaka pafupifupi 15 zachitukuko, magalimoto amagetsi atsopano apanga ma depositi ena aukadaulo.Kusankhidwa kwapre-charging resistoramatsimikizira liwiro la galimoto isanakwane nthawi yolipiritsa, kukula kwa malo omwe akugwiritsidwa ntchito ndi kukana kwapang'onopang'ono, chitetezo chamagetsi chamagetsi a galimoto, kudalirika ndi 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 chithyole capacitor.Mphamvu yamagetsi yamagetsi yomwe imawonjezedwa mwachindunji ku capacitor, yofanana ndi nthawi yofupikitsa, yomwe imakhala yochepa kwambiri imatha kuwononga zida zamagetsi zamagetsi.Choncho, popanga dera, kukana kwa chisanadze 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 chitsimikiziro chenicheni cha kapangidwe kameneka: ceramic resistor ndiyothandiza kwambiri, kutulutsa ndi zina zofunika.Ili ndi kutentha kwapadera kwapadera ndipo imatha kuyamwa mphamvu zambiri panthawi yolipiritsa mu nthawi yochepa.
