Thechotenthetsera batri chamagetsi chatsopano chagalimotoimatha kusunga batri pamalo oyenera kutentha kuti iwonetsetse kuti makina onse agalimoto akuyenda bwino. Kutentha kukakhala kotsika kwambiri, ma lithiamu ion awa amaundana, zomwe zimalepheretsa kuyenda kwawo, zomwe zimapangitsa kuti mphamvu yamagetsi ya batri itsike kwambiri. Chifukwa chake, nthawi yozizira kapena kutentha kukakhala kotsika kwambiri, ndikofunikira kutenthetsa batri pasadakhale.
Makina otenthetsera mabatire a magalimoto atsopano amagetsi amagetsi amagwiritsa ntchito njira ziwiri izi: kutenthetsera pasadakhale ndi kutenthetsera madzi amafuta. Mwa kuyika chotenthetsera madzi pagalimoto yatsopano yamagetsi, batire imatenthetsedwa ndi kusamutsa kutentha kuti ifike kutentha kwabwinobwino.Zotenthetsera zamagetsi zatsopano zamagetsi amphamvu kwambiriimatha kusamutsa kutentha kupita ku batire ya galimoto yamagetsi kuti itenthetsedwe pasadakhale ndikusunga kutentha kwabwinobwino poyiyikaZotenthetsera za PTCpa magalimoto atsopano amagetsi.
Njira yatsopano yotenthetsera mabatire amagetsi amagetsi. M'nyengo yozizira, moyo wa batire wa magalimoto amagetsi atsopano nthawi zambiri umachepa kwambiri, makamaka chifukwa kutentha kochepa, kukhuthala kwa electrolyte mu batire kumawonjezeka ndipo mphamvu ndi kutulutsa mphamvu kwa batire kumachepa.
Mwa chiphunzitso: N'koletsedwa kuchaja mabatire a lithiamu pamalo otentha madigiri Celsius osachepera 20 (zingayambitse kuwonongeka kwa batire). Magalimoto amagetsi amatha kuthetsa vuto la kuchepa kwa moyo wa batire ya magalimoto atsopano amagetsi m'malo otentha pang'ono m'nyengo yozizira poyika achotenthetsera magalimotokutenthetsa pasadakhale paketi ya batire ya magalimoto atsopano amphamvu kuti ikhale pa kutentha kwabwinobwino komanso kupewa kuwonongeka kwa paketi ya batire chifukwa cha kuchaja kwa kutentha kochepa.
Chotenthetsera cha PTC, chomwe chimatchedwansoChotenthetsera cha PTC, limapangidwa ndiPTC ceramic heating elementndi chubu cha aluminiyamu. Chotenthetsera cha PTC chamtunduwu chili ndi ubwino wochepa chifukwa cha kukana kutentha komanso kugwiritsa ntchito bwino kutentha kwambiri. Ndi kutentha kokhazikika komanso kusunga mphamvu zokhachotenthetsera chamagetsi. Chinthu chabwino kwambiri chili mu magwiridwe antchito. Izi zikutanthauza kuti, fani ikalephera ndikuyima, mphamvu ya chotenthetsera cha PTC imatsika yokha kwambiri chifukwa sichingathe kuwononga kutentha kokwanira. Panthawiyi, kutentha kwa pamwamba pa chotenthetsera kumakhalabe kutentha kwa Curie (nthawi zambiri 250°C) mmwamba ndi pansi), kuti tipewe "kufiira" pamwamba pa zotenthetsera zamagetsi, zomwe sizingayambitse kutentha, moto ndi zoopsa zina zobisika.
Ili ndi mapepala a aluminiyamu otulutsa kutentha, machubu a aluminiyamu, mapepala oyendetsera magetsi, mafilimu oteteza kutentha, mapepala otenthetsera a PTC, malo olumikizira magetsi a mkuwa opangidwa ndi nickel ndi ma electrode sheath apulasitiki otentha kwambiri. Chifukwa chogwiritsa ntchito ma heat sinks otenthetsera, mankhwalawa amawongolera kutentha kwake ndipo amaganizira mokwanira zinthu zosiyanasiyana zotenthetsera ndi zamagetsi za PTC heating element panthawi yogwira ntchito. Ili ndi mphamvu yolimba yolumikizira, kutentha kwabwino kwambiri komanso kutentha kwabwino, kugwira ntchito bwino komanso kudalirika. Mtundu uwu wa PTC heater uli ndi ubwino wochepa wa kutentha komanso mphamvu yosinthana kutentha kwambiri. Ndi heater yamagetsi yokhazikika yokha komanso yosunga mphamvu.
Mfundo ya chotenthetsera cha PTC Kutentha kwa kutentha kokhazikika kwa PTC thermistor imakhala ndi mawonekedwe otenthetsera kutentha kokhazikika. Mfundo yake ndi yakuti pambuyo poti PTC thermistor yayatsidwa, imadzitenthetsa yokha ndipo mphamvu yokana imalowa m'dera losinthira. Kutentha kwa pamwamba pa kutentha kokhazikika kwa PTC thermistor kumasunga mtengo wokhazikika. Kutentha kumangogwirizana ndi kutentha kwa Curie kwa PTC thermistor ndi voltage yomwe imagwiritsidwa ntchito, ndipo kwenikweni sikukhudzana ndi kutentha kozungulira.
