Mabatire angapo a lithiamu amatha kulumikizidwa motsatizana kuti apange paketi ya batri, yomwe imatha kupereka mphamvu ku katundu wosiyanasiyana ndipo imathanso kuchajidwa nthawi zonse ndi chojambulira chofananira. Mabatire a Lithium safuna njira iliyonse yoyendetsera mabatire (BMS) kuti ayambe kutchaja ndi kutulutsa. Nanga n’chifukwa chiyani mabatire onse a lithiamu omwe ali pamsika amawonjezera BMS? Yankho lake ndi chitetezo ndi moyo wautali.
Dongosolo loyang'anira mabatire la BMS (Battery Management System) limagwiritsidwa ntchito kuyang'anira ndikuwongolera kuyatsa ndi kutulutsa mabatire omwe angadzazidwenso. Ntchito yofunika kwambiri ya dongosolo loyang'anira mabatire la lithiamu (BMS) ndikuwonetsetsa kuti mabatire akukhalabe mkati mwa malire otetezeka ogwirira ntchito ndikuchitapo kanthu mwachangu ngati batire iliyonse iyamba kupitirira malire. Ngati BMS yazindikira kuti magetsi ndi otsika kwambiri, imachotsa katundu, ndipo ngati magetsi ndi okwera kwambiri, imachotsa chojambulira. Idzawonanso kuti selo lililonse lomwe lili mu paketi lili pamagetsi ofanana ndikuchepetsa magetsi aliwonse omwe ali okwera kuposa maselo ena. Izi zimatsimikizira kuti batire silifika pamagetsi okwera kwambiri kapena otsika kwambiri.–zomwe nthawi zambiri zimakhala chifukwa cha moto wa lithiamu womwe timawona m'nkhani. Imatha kuyang'anira kutentha kwa batri ndikuchotsa paketi ya batri isanayambe kutentha kwambiri kuti isagwire moto. Chifukwa chake, njira yoyendetsera mabatire ya BMS imalola batri kutetezedwa m'malo mongodalira chojambulira chabwino kapena kugwiritsa ntchito koyenera kwa wogwiritsa ntchito.
Chifukwa chiyani osatero'Kodi mabatire a lead-acid amafunika njira yoyendetsera mabatire? Kapangidwe ka mabatire a lead-acid sikoyaka kwambiri, zomwe zimapangitsa kuti asagwire moto ngati pali vuto la kuchaja kapena kutulutsa. Koma chifukwa chachikulu chikugwirizana ndi momwe batire imachitira ikakhala ndi chaji yokwanira. Mabatire a lead-acid amapangidwanso ndi maselo olumikizidwa motsatizana; ngati selo imodzi ili ndi chaji yochulukirapo kuposa maselo ena, imangolola mphamvu kudutsa mpaka maselo ena atakhala ndi chaji yokwanira, pomwe ikusunga magetsi oyenera, ndi zina zotero. Maselo amafika. Mwanjira imeneyi, mabatire a lead-acid "amakhazikika okha" akamachaja.
Mabatire a Lithium ndi osiyana. Ma electrode abwino a mabatire a lithiamu omwe angadzazidwenso nthawi zambiri amakhala ndi zinthu za lithiamu ion. Mfundo yake yogwirira ntchito imatsimikizira kuti panthawi yochaja ndi kutulutsa, ma electron a lithiamu adzayenda mbali zonse ziwiri za ma electrode abwino ndi oipa mobwerezabwereza. Ngati magetsi a selo limodzi aloledwa kukhala okwera kuposa 4.25v (kupatula mabatire a lithiamu amphamvu kwambiri), kapangidwe ka anode microporous kangagwe, zinthu zolimba za kristalo zimatha kukula ndikuyambitsa short circuit, kenako kutentha kudzakwera mofulumira, zomwe pamapeto pake zimayambitsa moto. Batire ya lithiamu ikadzadza mokwanira, magetsi amakwera mwadzidzidzi ndipo amatha kufika pamlingo woopsa mwachangu. Ngati magetsi a selo linalake mu batire ndi okwera kuposa a maselo ena, selo ili lidzafika pamagetsi owopsa poyamba panthawi yochaja. Pakadali pano, magetsi onse a batire sanafike pamtengo wokwanira, ndipo chochaja sichidzasiya kuchaja. Chifukwa chake, maselo omwe amafika pamagetsi owopsa poyamba amayambitsa zoopsa zachitetezo. Chifukwa chake, kuwongolera ndi kuyang'anira magetsi onse a batire sikokwanira pa mankhwala a lithiamu. BMS iyenera kuyang'ana mphamvu ya magetsi ya selo iliyonse yomwe imapanga batire.
Chifukwa chake, kuti zitsimikizire kuti mabatire a lithiamu ndi otetezeka komanso a nthawi yayitali, BMS yoyendetsera bwino komanso yodalirika ndiyofunikira.
