Funso lofala limabuka: kodi BMS ya batri ya lithiamu-ion imayambitsa chitetezo cha overcharge, ndipo njira yoyenera yochiritsira ndi iti?
Chitetezo cha mphamvu yowonjezereka ya mabatire a lithiamu-ion chimayamba pamene chilichonse mwa zinthu ziwirizi chakwaniritsidwa. Choyamba, selo limodzi limafika pa mphamvu yake yowonjezereka. Kachiwiri, mphamvu yonse ya batire imafika pamlingo wovomerezeka wa mphamvu yowonjezereka. Mwachitsanzo, maselo a lead-acid ali ndi mphamvu yowonjezereka ya 3.65V, koteroBMSNthawi zambiri imayika mphamvu yamagetsi yowonjezera mphamvu ya selo limodzi kukhala 3.75V, ndipo chitetezo chamagetsi chonse chimawerengedwa ngati 3.7V chochulukitsidwa ndi chiwerengero cha maselo. Pa mabatire a lithiamu atatu, mphamvu yamagetsi yonse ndi 4.2V pa selo iliyonse, kotero chitetezo cha mphamvu yamagetsi yowonjezera mphamvu ya BMS imayikidwa pa 4.25V, ndipo chitetezo chamagetsi onse ndi 4.2V kuchulukitsa chiwerengero cha maselo.
Funso lomwe limafunsidwa kawirikawiri pakati pa ogwiritsa ntchito: Kodi kusiya batire ya EV yoyatsidwa usiku wonse (kuyambira pakati pausiku mpaka tsiku lotsatira) kumaiwononga pakapita nthawi? Yankho limadalira momwe zinthu zilili. Ngati batire ndi chojambulira zikugwirizana ndi wopanga zida zoyambirira (OEM), palibe chifukwa chodera nkhawa - BMS imapereka chitetezo chodalirika. Nthawi zambiri, mphamvu yoteteza mphamvu ya BMS imakwera kuposa mphamvu yotulutsa mphamvu ya chojambulira. Maselo akamasunga kukhazikika bwino (monga mabatire atsopano), chitetezo cha mphamvu yowonjezereka sichidzayambitsidwa pambuyo pochaja mokwanira. Pamene batire ikukalamba, kukhazikika kwa maselo kumachepa, ndipo BMS imayamba kupereka chitetezo.
Chodziwika bwino n'chakuti, pali kusiyana kwa magetsi pakati pa mphamvu ya BMS yowonjezerera mphamvu ndi mphamvu yobwezeretsa mphamvu. Mphamvu yamagetsi yosungidwa iyi imaletsa kuzungulira koopsa: kuyatsa chitetezo → kutsika kwa mphamvu yamagetsi → kutulutsidwa kwa chitetezo → kubwezeretsanso mphamvu → kutetezanso mphamvu, zomwe zimathandiza kukulitsa moyo wa batri. Kuti mukhale otetezeka komanso okhalitsa, njira yabwino kwambiri ndikuyiyika pachaja nthawi iliyonse yomwe mukufuna ndikuchotsa choyikiracho batri ikadzaza mphamvu.
