New Energy Vehicle Thermal Management - Battery System Thermal Management

Monga gwero lalikulu lamagetsi amagetsi atsopano, mabatire amphamvu ndi ofunikira kwambirimagalimoto atsopano amphamvu.Panthawi yogwiritsira ntchito galimotoyo, batire idzakumana ndi zovuta komanso zosinthika zogwirira ntchito.Pofuna kukonza maulendo oyendayenda, galimotoyo imayenera kukonza mabatire ambiri momwe zingathere pamalo enaake, kotero kuti malo a batire pagalimoto ndi ochepa kwambiri.Batire imapanga kutentha kwakukulu panthawi yogwiritsira ntchito galimotoyo ndipo imadziunjikira pamalo ang'onoang'ono pakapita nthawi.Chifukwa cha kuchulukirachulukira kwa ma cell mu batire paketi, zimakhalanso zovuta kutulutsa kutentha pakati pagawo lapakati mpaka pamlingo wina, kukulitsa kusagwirizana kwa kutentha pakati pa ma cell, zomwe zimachepetsa kuthamangitsa ndi kutulutsa mphamvu ya batire ndi zimakhudza mphamvu ya batri;Zidzayambitsa kuthawa kwa kutentha ndikukhudza chitetezo ndi moyo wa dongosolo.
Kutentha kwa batire yamphamvu kumakhudza kwambiri magwiridwe ake, moyo ndi chitetezo.Pa kutentha kochepa, kukana kwamkati kwa mabatire a lithiamu-ion kudzawonjezeka ndipo mphamvu idzachepa.Zikavuta kwambiri, electrolyte imaundana ndipo batire silingathe kutulutsidwa.Kutsika kwa kutentha kwa dongosolo la batri kudzakhudzidwa kwambiri, zomwe zimapangitsa kuti magetsi azigwira ntchito.Kutentha ndi kuchepetsa kutentha.Mukamalipira magalimoto amphamvu atsopano pansi pa kutentha kochepa, BMS yamba imatenthetsa batire pa kutentha koyenera isanalipire.Ngati sichikugwiridwa bwino, zimabweretsa kuchulukira kwamagetsi nthawi yomweyo, zomwe zimapangitsa kuti pakhale gawo lalifupi lamkati, komanso utsi wina, moto kapena kuphulika kumatha kuchitika.Vuto la chitetezo chotsika kutentha kwamagetsi amagetsi amagetsi amaletsa kukwezedwa kwa magalimoto amagetsi m'madera ozizira kwambiri.
Kuwongolera kutentha kwa batrindi imodzi mwazinthu zofunika kwambiri mu BMS, makamaka kusunga batire paketi ikugwira ntchito molingana ndi kutentha nthawi zonse, kuti ikhalebe ndi magwiridwe antchito abwino kwambiri a paketi ya batri.Kuwongolera kwamafuta a batrimakamaka zikuphatikizapo ntchito kuzirala, Kutenthetsa ndi kutentha equalization.Ntchito zoziziritsa ndi zotentha zimasinthidwa makamaka kuti zitheke kutentha kwakunja kwa batire.Kutentha kwa kutentha kumagwiritsidwa ntchito kuchepetsa kusiyana kwa kutentha mkati mwa paketi ya batri ndikuletsa kuwola kofulumira chifukwa cha kutenthedwa kwa gawo lina la batri.
