Popeza mabatire amphamvu ndi ofunika kwambiri kwa magalimoto atsopano amphamvu, mabatire amphamvu ndi ofunika kwambiri kwa magalimoto atsopano amphamvu. Pakagwiritsidwa ntchito galimoto, batireyo imayang'anizana ndi zovuta komanso zosintha ntchito. Pofuna kukonza malo oyendera, galimotoyo iyenera kukonza mabatire ambiri momwe ingathere pamalo enaake, kotero malo a batire pagalimoto ndi ochepa kwambiri. Batireyo imapanga kutentha kwambiri panthawi yogwira ntchito ya galimotoyo ndipo imasonkhana pamalo ochepa pakapita nthawi. Chifukwa cha kuchuluka kwa maselo mu batire, zimakhala zovuta kwambiri kutulutsa kutentha pakati pa malo enaake, zomwe zimapangitsa kuti kutentha kusamayende bwino pakati pa maselo, zomwe zimachepetsa kuyatsa ndi kutulutsa mphamvu kwa batire ndikukhudza mphamvu ya batire; Zingayambitse kutentha ndipo zimakhudza chitetezo ndi moyo wa dongosolo.
Kutentha kwa batire yamagetsi kumakhudza kwambiri magwiridwe antchito ake, moyo wake, komanso chitetezo chake. Pa kutentha kochepa, kukana kwamkati kwa mabatire a lithiamu-ion kumawonjezeka ndipo mphamvu yake imachepa. Nthawi zambiri, electrolyte imazizira ndipo batire silingathe kutulutsidwa. Kugwira ntchito kwa batire yotsika kutentha kudzakhudzidwa kwambiri, zomwe zimapangitsa kuti mphamvu zamagetsi zigwire ntchito bwino. Kuchepa kwa kutentha ndi kutsika kwa liwiro. Mukachaja magalimoto atsopano amagetsi pansi pa kutentha kochepa, BMS yonse imatenthetsa batireyo kutentha koyenera isanachajidwe. Ngati sichiyendetsedwa bwino, chimabweretsa kukwera kwa mphamvu yamagetsi nthawi yomweyo, zomwe zimapangitsa kuti magetsi aziyenda pang'onopang'ono, ndipo utsi wina, moto kapena kuphulika kungachitike. Vuto la chitetezo cha batire yamagetsi yotsika kutentha limalepheretsa kukwezedwa kwa magalimoto amagetsi m'malo ozizira kwambiri.
Kusamalira kutentha kwa batri ndi ntchito yofunika kwambiri mu BMS, makamaka kuti batri igwire ntchito bwino nthawi zonse, kuti batri igwire bwino ntchito. Kusamalira kutentha kwa batri kumaphatikizapo ntchito zoziziritsa, kutentha ndi kulinganiza kutentha. Ntchito zoziziritsa ndi kutentha zimasinthidwa makamaka kuti zigwirizane ndi momwe kutentha kwakunja kwa batri kungakhudzire. Kulinganiza kutentha kumagwiritsidwa ntchito kuchepetsa kusiyana kwa kutentha mkati mwa batri ndikuletsa kuwonongeka mwachangu komwe kumachitika chifukwa cha kutentha kwambiri kwa gawo lina la batri.
Kawirikawiri, njira zoziziritsira mabatire amagetsi zimagawidwa m'magulu atatu: kuziziritsa mpweya, kuziziritsa madzi ndi kuziziritsa mwachindunji. Njira yoziziritsira mpweya imagwiritsa ntchito mphepo yachilengedwe kapena mpweya woziziritsa m'chipinda chonyamulira anthu kuti iyende pamwamba pa batire kuti ikwaniritse kusinthana kutentha ndi kuziziritsa. Kuziziritsa madzi nthawi zambiri kumagwiritsa ntchito payipi yodziyimira payokha yoziziritsira kutentha kapena kuziziritsa batire yamagetsi. Pakadali pano, njira iyi ndiyo njira yayikulu yoziziritsira. Mwachitsanzo, Tesla ndi Volt onse amagwiritsa ntchito njira yoziziritsirayi. Njira yoziziritsira mwachindunji imachotsa payipi yoziziritsira ya batire yamagetsi ndipo imagwiritsa ntchito mwachindunji refrigerant kuti iziritse batire yamagetsi.
1. Makina oziziritsira mpweya:
M'mabatire oyambirira amagetsi, chifukwa cha mphamvu zawo zochepa komanso kuchuluka kwa mphamvu, mabatire ambiri amagetsi ankazizidwa ndi kuzizira kwa mpweya.Chotenthetsera Mpweya cha PTC) imagawidwa m'magulu awiri: kuziziritsa mpweya mwachilengedwe ndi kuzizira mpweya mokakamizidwa (pogwiritsa ntchito fani), ndipo imagwiritsa ntchito mphepo yachilengedwe kapena mpweya wozizira mu kabati kuti iziziritse batire.
Oimira machitidwe oziziritsidwa ndi mpweya ndi Nissan Leaf, Kia Soul EV, ndi zina zotero; pakadali pano, mabatire a 48V a magalimoto ang'onoang'ono osakanizidwa a 48V nthawi zambiri amakhala m'chipinda chonyamulira anthu, ndipo amaziziritsidwa ndi mpweya. Kapangidwe ka makina oziziritsira mpweya ndi kosavuta, ukadaulo wake ndi wokhwima, ndipo mtengo wake ndi wotsika. Komabe, chifukwa cha kutentha kochepa komwe kumachotsedwa ndi mpweya, mphamvu yake yosinthira kutentha ndi yotsika, kutentha kwa mkati kwa batire sikwabwino, ndipo n'kovuta kupeza kuwongolera kolondola kwa kutentha kwa batire. Chifukwa chake, makina oziziritsira mpweya nthawi zambiri amakhala oyenera zochitika zokhala ndi nthawi yochepa yoyenda komanso kulemera kopepuka kwa galimoto.
Ndikoyenera kunena kuti pa makina oziziritsidwa ndi mpweya, kapangidwe ka njira yoziziritsira mpweya kamakhala ndi gawo lofunika kwambiri pakuziziritsa. Njira zoziziritsira mpweya zimagawidwa makamaka m'njira zoziziritsira mpweya ndi njira zoziziritsira mpweya zofanana. Kapangidwe ka njira yoziritsira ndi kosavuta, koma kukana kwake ndi kwakukulu; kapangidwe kofanana ndi kovuta kwambiri ndipo kamatenga malo ambiri, koma kufanana kwa kutentha ndi kwabwino.
2. Makina ozizira amadzimadzi
Njira yoziziritsira madzi imatanthauza kuti batire imagwiritsa ntchito madzi ozizira posinthana kutentha (Chotenthetsera Choziziritsira cha PTCChoziziritsira chimagawika m'magulu awiri omwe amatha kukhudza mwachindunji selo ya batri (mafuta a silicon, mafuta a castor, ndi zina zotero) ndikukhudza selo ya batri (madzi ndi ethylene glycol, ndi zina zotero) kudzera m'njira zamadzi; pakadali pano, yankho losakanikirana la madzi ndi ethylene glycol limagwiritsidwa ntchito kwambiri. Dongosolo loziziritsira lamadzi nthawi zambiri limawonjezera choziziritsira kuti chigwirizane ndi kayendedwe ka firiji, ndipo kutentha kwa batri kumachotsedwa kudzera mu refrigerant; zigawo zake zazikulu ndi compressor, choziziritsira ndipampu yamadzi yamagetsiMonga gwero la mphamvu yoziziritsira, compressor imazindikira mphamvu yosinthira kutentha kwa dongosolo lonse. Chiller chimagwira ntchito ngati kusinthana pakati pa refrigerant ndi madzi ozizira, ndipo kuchuluka kwa kusinthana kutentha kumatsimikiza mwachindunji kutentha kwa madzi ozizira. Pampu yamadzi imatsimikiza kuchuluka kwa madzi ozizira mu payipi. Kuthamanga kwa madzi kukakhala kofulumira, kumabweretsanso mphamvu yosamutsa kutentha, komanso mosemphanitsa.
