Tom qab ze li ntawm 10 xyoo ntawm txoj kev loj hlob, lub zog tshiab hluav taws xob tsheb tau tsim qee qhov kev tso nyiaj. Kev tsim cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob muaj ntau yam kev paub, ntawm cov qauv tsimprecharge resistornyob rau hauv lub pre-them Circuit Court yuav tsum tau xav txog ntau yam kev mob thiab kev ua hauj lwm tej yam kev mob. Kev xaiv ntawm precharge resistor txiav txim siab qhov ceev ntawm lub tsheb pre-them lub sij hawm, qhov luaj li cas ntawm qhov chaw nyob los ntawm lub precharge resistor, lub tsheb lub high voltage kev nyab xeeb, kev cia siab thiab stability.
Precharge resistoryog ib tug resistor uas maj mam tsub lub capacitor thaum ntxov ntawm lub tsheb lub high-voltage fais fab tuag, yog hais tias tsis muaj pre-charge resistor, lub charger tam sim no yuav loj heev kom tawg lub capacitor. High-voltage fais fab ntxiv ncaj qha mus rau lub capacitor, sib npaug rau ib qho luv luv tam sim no, dhau qhov luv luv tam sim no yuav ua rau cov hluav taws xob muaj hluav taws xob puas. Yog li ntawd, thaum tsim lub Circuit Court, lub precharge resistor yuav tsum tau coj mus rau hauv tus account kom ntseeg tau tias muaj kev ruaj ntseg ntawm Circuit Court.
Muaj ob qhov chaw nyob rau hauv high-voltage circuit ntawm ib lub tsheb hluav taws xob qhov twgprecharge resistoryog siv, uas yog lub cev muaj zog controller precharge circuit thiab high-voltage accessory pre-charging circuit. Lub cev muaj zog maub los (inverter Circuit Court) muaj lub capacitor loj, uas yuav tsum tau them ua ntej los tswj lub capacitor them tam sim no. High-voltage accessories feem ntau kuj muaj DCDC (DC converter), OBC (on-board charger), PDU (high-voltage tis box), roj twj tso kua mis, twj tso kua mis, AC (cua txias compressor) thiab lwm yam, yuav muaj. ib tug loj capacitance nyob rau hauv cov khoom, yog li lawv yuav tsum tau pre-them.
