Pambuyo pazaka pafupifupi 10 zachitukuko, magalimoto amagetsi atsopano apanga ukadaulo wina. Pali chidziwitso chochuluka pakupanga zida zamagetsi zamagetsi ndikusankha ndi kufananiza zigawo. Pakati pawo, mapangidwe a precharge resistor mu precharge dera ayenera kuganizira zinthu zambiri ndi mmene ntchito. Kusankhidwa kwa precharge resistor kumatanthawuza kuthamanga kwa nthawi yoyendetsera galimoto, kukula kwa malo omweprecharge resistor, ndi chitetezo, kudalirika, ndi kukhazikika kwa magetsi okwera kwambiri a galimoto.
Precharge resistor ndi resistor yomwe imayendetsa pang'onopang'ono capacitor kumayambiriro kwa mphamvu yamagetsi yamoto. Ngati palibe choletsa cha precharge, kuthamanga kwambiri kumasokoneza capacitor. Magetsi okwera kwambiri amagwiritsidwa ntchito mwachindunji ku capacitor, yomwe imakhala yofanana ndi nthawi yochepa. Kuchulukirachulukira kwakanthawi kochepa kumawononga zida zamagetsi zamagetsi.Chifukwa chake, choletsa cha precharge chiyenera kuganiziridwa popanga dera kuti zitsimikizire chitetezo chadera.
Pali malo awiri kumeneprecharge resistorsamagwiritsidwa ntchito pamagetsi apakatikati ndi apamwamba pamagalimoto amagetsi, monga motor controller precharge circuit ndi high voltage accessory precharge circuit. Pali capacitor yayikulu mu chowongolera ma motor (inverter circuit), yomwe imayenera kuyitanidwa kuti iwononge capacitor pakali pano. Zida zokhala ndi magetsi apamwamba nthawi zambiri zimaphatikizapo DCDC (DC converter), OBC (chaja pa bolodi), PDU (bokosi logawa mphamvu yamagetsi), pampu yamafuta, pampu yamadzi, AC (compressor air conditioning) ndi zina, ndipo palinso zina. ma capacitor akuluakulu mkati mwa zigawo. , kotero kuti kulipiritsa kumafunika.
Precharge resistorsR, precharge time T, ndi precharge capacitor C yofunikira, nthawi yochapira nthawi zambiri imakhala 3 mpaka 5 ku RC, ndipo nthawi yochapira nthawi zambiri imakhala ma milliseconds. Choncho, precharging ikhoza kumalizidwa mwamsanga ndipo sikungakhudze njira yoyendetsera galimoto. Mkhalidwe woweruza ngati precharging yamalizidwa ndikuti ifika 90% yamagetsi amagetsi amagetsi (nthawi zambiri ndi choncho). Posankha precharge resistor, zotsatirazi ziyenera kuganiziridwa: mphamvu ya batri yamagetsi, contactor ovotera panopa, capacitor C mtengo, pazipita yozungulira kutentha, kutentha kwa resistor, voteji pambuyo precharge, nthawi precharge, insulation resistance, pulse mphamvu. Kuwerengera kwa mphamvu ya pulse ndi theka lachinthu cha sikweya ya voteji ya pulse ndi capacitance C mtengo. Ngati ndi kugunda kosalekeza, ndiye kuti mphamvu zonse ziyenera kukhala kuchuluka kwa mphamvu zamagulu onse.
