Pambuyo pazaka pafupifupi 10 zachitukuko, magalimoto amagetsi atsopano apanga ma depositi ena aukadaulo.Mapangidwe a magawo a galimoto yamagetsi ndi zigawo zake ali ndi chidziwitso chochuluka, chomwe chimapangidwiraprecharge resistormu dera chisanadze kulipiritsa ayenera kuganizira zambiri mikhalidwe ndi mmene ntchito.Kusankhidwa kwa precharge resistor kumatanthawuza kuthamanga kwa galimoto isanayambe kulipiritsa nthawi, kukula kwa malo omwe ali ndi precharge resistor, chitetezo chapamwamba cha galimoto, kudalirika ndi kukhazikika.
Precharge resistorndi chotsutsa chomwe chimayendetsa pang'onopang'ono capacitor kumayambiriro kwa mphamvu yamagetsi yamagetsi yamoto, ngati palibe chotsutsa chisanadze, chiwongoladzanja chidzakhala chachikulu kwambiri kuti chiwononge 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, precharge resistor iyenera kuganiziridwa kuti zitsimikizire chitetezo cha dera.
Pali malo awiri mu dera lapamwamba lamagetsi agalimoto yamagetsi komweprecharge resistoramagwiritsidwa ntchito, monga motor controller precharge circuit ndi high-voltage accessory pre-charging circuit.The motor controller (inverter circuit) ili ndi capacitor yaikulu, yomwe imayenera kulipira kale kuti iwononge mphamvu ya capacitor.Chalk chamagetsi chamagetsi chimakhalanso ndi DCDC (DC converter), OBC (chaja pa bolodi), PDU (bokosi logawa lamagetsi), pampu yamafuta, pampu yamadzi, AC (compressor air-conditioning) ndi magawo ena, padzakhala capacitance lalikulu mkati mwa zigawo, kotero iwo ayenera chisanadze mlandu.
