Tambayar da aka saba yi ita ce: a wane yanayi ne BMS na batirin lithium-ion ke kunna kariyar caji mai yawa, kuma menene hanyar da ta dace don murmurewa daga gare ta?
Kariyar caji mai yawa ga batirin lithium-ion yana tasowa ne lokacin da aka cika ɗayan sharuɗɗa biyu. Da farko, tantanin halitta ɗaya ya kai ƙarfin cajin da aka ƙayyade. Na biyu, jimlar ƙarfin fakitin batirin ya cika ƙa'idar cajin da aka ƙayyade. Misali, ƙwayoyin gubar acid suna da ƙarfin cajin da ya wuce kima na 3.65V, don haka BMS yawanci yana saita ƙarfin cajin da ya wuce kima na tantanin halitta ɗaya zuwa 3.75V, tare da jimlar kariyar wutar lantarki da aka ƙididdige azaman 3.7V ninka ta adadin ƙwayoyin. Ga batirin lithium na ternary, cikakken ƙarfin caji shine 4.2V kowace tantanin halitta, don haka an saita kariyar cajin da ya wuce kima ta BMS zuwa 4.25V, kuma jimlar yanayin kariyar wutar lantarki shine 4.2V sau adadin ƙwayoyin.
Tambayar da ake yawan yi tsakanin masu amfani: Shin barin batirin EV ya yi caji cikin dare ɗaya (daga tsakar dare har zuwa washegari) yana lalata shi a cikin dogon lokaci? Amsar ta dogara ne akan takamaiman saitin. Idan batirin da caja sun dace da masana'antar kayan aiki na asali (OEM), babu buƙatar damuwa - BMS yana ba da kariya mai inganci. Yawanci, ƙarfin kariya na BMS ya fi ƙarfin fitarwa na caja. Lokacin da ƙwayoyin halitta ke kiyaye daidaito mai kyau (kamar a cikin sabbin batura), ba za a kunna kariyar caji mai yawa ba bayan cikakken caji. Yayin da batirin ya tsufa, daidaiton tantanin halitta yana raguwa, kuma BMS yana shiga don samar da kariya.
Abin lura shi ne, akwai gibin wutar lantarki tsakanin ƙarfin wutar lantarki na BMS mai ƙara caji da kuma matakin dawowa. Wannan kewayon wutar lantarki da aka tanada yana hana zagayowar cutarwa: kunna kariya → faɗuwar wutar lantarki → sakin kariya → sake caji → sake karewa, wanda ke taimakawa wajen tsawaita rayuwar batirin. Don mafi girman aminci da tsawon rai, mafi kyawun aikin shine a yi caji akan buƙata kuma a cire caja da zarar batirin ya cika caji.
