Monga gwero lalikulu lamagetsi amagetsi atsopano, mabatire amphamvu ndi ofunikira kwambiri pamagalimoto amagetsi atsopano.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 matenthedwe a batri ndi imodzi mwazinthu zofunika kwambiri mu BMS, makamaka kusunga batire kuti igwire ntchito moyenerera kutentha nthawi zonse, kuti ikhalebe yogwira ntchito bwino ya paketi ya batri.Kuwongolera kutentha kwa batri makamaka kumaphatikizapo ntchito zoziziritsa, kutentha ndi kutentha mofanana.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.
Nthawi zambiri, kuzirala kwa mabatire amphamvu amagawidwa m'magulu atatu: kuziziritsa kwa mpweya, kuziziritsa kwamadzi ndi kuzizirira mwachindunji.Njira yozizirira mpweya imagwiritsa ntchito mphepo yachilengedwe kapena mpweya woziziritsa m'chipinda cha anthu okwera kupita pamwamba pa batire kuti ikwaniritse kutentha ndi kuziziritsa.Kuziziritsa kwamadzi nthawi zambiri kumagwiritsa ntchito payipi yozizirira yodziyimira yokha kutenthetsa kapena kuziziritsa batire yamagetsi.Pakalipano, njira iyi ndiyo njira yoyamba yozizira.Mwachitsanzo, Tesla ndi Volt onse amagwiritsa ntchito njira yozizira iyi.Dongosolo lozizira lachindunji limachotsa payipi yoziziritsa ya batri yamagetsi ndipo imagwiritsa ntchito firiji mwachindunji kuziziritsa batire yamagetsi.
1. Dongosolo lozizira mpweya:
M'mabatire oyambilira amagetsi, chifukwa cha mphamvu zawo zazing'ono komanso kachulukidwe kamphamvu, mabatire ambiri amphamvu adazizidwa ndi kuziziritsa kwa mpweya.Kuziziritsa mpweya (PTC Air Heater) amagawidwa m'magulu awiri: kuziziritsa kwachilengedwe ndi kuzizira kwa mpweya mokakamiza (pogwiritsa ntchito fan), ndipo amagwiritsa ntchito mphepo yachilengedwe kapena mpweya wozizira mu kabati kuziziritsa batire.
Oimira odziwika bwino a makina oziziritsa mpweya ndi Nissan Leaf, Kia Soul EV, etc.;pakadali pano, mabatire a 48V a magalimoto ang'onoang'ono a 48V nthawi zambiri amakonzedwa m'chipinda chokwera, ndipo amazizidwa ndi kuziziritsa mpweya.Mapangidwe a makina oziziritsa mpweya ndi osavuta, teknoloji ndi yokhwima, ndipo mtengo wake ndi wotsika.Komabe, chifukwa cha kutentha kochepa komwe kumachotsedwa ndi mpweya, kutentha kwake kwa kutentha kumakhala kochepa, kutentha kwa mkati kwa batri sikwabwino, ndipo n'zovuta kukwaniritsa kuwongolera bwino kwa kutentha kwa batri.Chifukwa chake, makina oziziritsa mpweya nthawi zambiri amakhala oyenera malo okhala ndi maulendo afupiafupi komanso kulemera kwagalimoto yopepuka.
Ndikoyenera kunena kuti pamakina oziziritsa mpweya, kapangidwe kake ka mpweya kamakhala ndi gawo lofunikira pakuzizira.Ma ducts a mpweya amagawidwa kukhala ma serial air ducts ndi ma parallel air ducts.Mapangidwe a serial ndi osavuta, koma kukana ndi kwakukulu;mawonekedwe ofanana ndi ovuta kwambiri ndipo amatenga malo ochulukirapo, koma kufanana kwa kutentha kwa kutentha kuli bwino.
2. Dongosolo lozizira lamadzimadzi
Kuzizira kwamadzimadzi kumatanthauza kuti batire imagwiritsa ntchito madzi ozizira kusinthanitsa kutentha (PTC Coolant Heater).Coolant akhoza kugawidwa mu mitundu iwiri yomwe ingathe kukhudzana ndi batri (mafuta a silicon, mafuta a castor, etc.) ndi kukhudzana ndi selo la batri (madzi ndi ethylene glycol, etc.) kudzera mumtsinje wamadzi;pakali pano, njira yosakanikirana ya madzi ndi ethylene glycol imagwiritsidwa ntchito kwambiri.Makina ozizirira amadzimadzi nthawi zambiri amawonjezera kuzizira kuti agwirizane ndi nthawi ya firiji, ndipo kutentha kwa batire kumachotsedwa kudzera mufiriji;zigawo zake zikuluzikulu ndi kompresa, chiller ndipompa madzi amagetsi.Monga gwero lamphamvu la firiji, kompresa imatsimikizira mphamvu yosinthira kutentha kwa dongosolo lonse.Chozizira chimagwira ntchito ngati kusinthanitsa pakati pa refrigerant ndi madzi ozizira, ndipo kuchuluka kwa kutentha kumatsimikizira mwachindunji kutentha kwa madzi ozizira.Pampu yamadzi imatsimikizira kuchuluka kwa zoziziritsa kukhosi mupaipi.Kuthamanga kwachangu, kumapangitsanso kutentha kwabwinoko, komanso mosiyana.
