Ma capacitor apamwamba a mafilimu amphamvu okhala ndi ukadaulo wodzichiritsa wokha ndi amodzi mwa mayankho amagetsi amphamvu omwe mainjiniya a EV ndi HEV angadalire kuti akwaniritse kukula kolimba, kulemera, magwiridwe antchito, komanso kudalirika kosalephera konse pamsika wovutawu.

Ma capacitor amagetsi amphamvu omwe amatha kupereka mayankho odalirika a mapangidwe a EV ndi HEV ayenera kukwaniritsa magawo angapo okhudzana ndi zipangizo zachitsulo, kukonza, ndi kapangidwe ka filimu.

Chitukuko chokhazikika chakhala lingaliro lofunika kwambiri komanso lofala kwambiri m'nthawi yamakono. Makamaka, m'makampani opanga mphamvu, njira zoyera komanso zongowonjezwdwanso mphamvu zikulowa m'malo mwa njira zachikhalidwe zopangira mafuta. Popeza EV ndi HEV ndi msika womwe ukukwera, ma inverter amafunika kukhala ndi kukula kochepa, kuchuluka kwa mphamvu, kugawanika kwakukulu (WGB) komanso kulephera konse kuti alowe m'malo mwa injini yachikhalidwe yoyaka moto (ICE). Zotsatira zake, capacitor ya filimu yachitsulo ndi chinthu chofunikira kwambiri kuti EV ndi HEV zamtsogolo zikwaniritse zofunikira pamsika.

Kachipangizo ka filimu kopangidwa ndi zitsulo ku CRE kali ndi mphamvu yodzichiritsa yokha, yomwe ingathe kuletsa kulephera kwakukulu pakachitika vuto la mkati. Kachipangizo ka dielectric mu capacitor yathu kamakutidwa ndi zinthu zachitsulo zomwe zimayikidwa mu vacuum ndipo zimakhala ndi makulidwe a nanometers makumi angapo okha. Pakakhala malo ofooka kapena kusayera pa dielectric, kuwonongeka kumachitika. Mphamvu yomwe imatulutsidwa ndi kutuluka kwa arc pa kuwonongekako idzakhala yokwanira kuwononga chitsulo chozungulira, kupatula cholakwikacho ndikuchiritsa bwino capacitor kuti ipitirize kugwira ntchito.

Ndi ukadaulo wodzichiritsa wokha uwu, ma capacitor athu a filimu opangidwa ndi zitsulo amagwiritsidwa ntchito pa zosowa zosiyanasiyana zamsika ndipo amatha kukwaniritsa zofunikira zamagetsi zapamwamba kuphatikiza za ma inverters omwe amagwiritsidwa ntchito mu EV ndi HEV. Ali ndi nthawi yayitali komanso kudalirika kogwira ntchito popanda kulephera konse. Kuphatikiza pa zabwino zomwe zimapezeka chifukwa cha kudzichiritsa, ma capacitor athu nawonso ndi ang'onoang'ono okhala ndi capacitance yayikulu. Amatha kuyikidwa mosavuta ndipo amatha kupirira mphamvu zamagetsi zambiri.

Ma capacitor a filimu opangidwa ndi chitsulo amagwiritsidwa ntchito ndi mapangidwe a patent a CRE. Nthawi zambiri amathiridwa ndi utomoni wouma, wopindidwa ndi tepi ya Myra ndikutsekedwa ndi chipolopolo chachitsulo kapena pulasitiki. Kapangidwe ka patent kadzabweretsa zabwino zosiyanasiyana kuphatikiza kulinganiza mphamvu yamagetsi ndi inductance, palibe kukulitsa kutentha kwakukulu, mphamvu yamagetsi yambiri komanso mtengo wotsika wopanga. Bobbin yama capacitor angapo ikhoza kugulitsidwa mu kapangidwe ka bus bar kuti ipereke ma inductance otsika omwe angagwiritsidwe ntchito kuchepetsa over-voltage panthawi yosintha.

Monga njira imodzi yothanirana ndi kusintha kwa mphamvu zoyera komanso chitukuko chokhazikika, msika wa EV ndi HEV ukuyembekezeka kukulirakulira nthawi zonse ndipo pamapeto pake udzasintha mitundu ya ICE. Ma capacitor a filimu opangidwa ndi zitsulo ku Wuxi CRE adzakhala njira yothandiza, yodalirika komanso yotsogola pakupanga kwanu kwamtsogolo.
