Lokacin cajin baturin lithium-ion, cajin halin yanzu da ƙarfin caji ya kamata a sarrafa su gwargwadon tsarin lokaci.Don haka, aikin bincike kan cajar baturi na lithium-ion dole ne a aiwatar da shi sannu a hankali bisa la’akari da fahintar yanayin cajinsa da fitar da shi, wato manyan abubuwan da suka shafi aikin caji na batir lithium-ion: wutar lantarki da halin yanzu.
1. Voltage.Matsakaicin ƙarfin lantarki na batirin lithium-ion gabaɗaya 3.6V ko 3.7V (dangane da masana'anta).Wutar ƙarewar caji (wanda kuma ake kira floating voltage ko floating voltage) gabaɗaya 4.1V, 4.2V, da sauransu, ya danganta da takamaiman kayan lantarki.Gabaɗaya, ƙarfin ƙarewa shine 4.2V lokacin da kayan lantarki mara kyau shine graphite, kuma ƙarfin ƙarewa shine 4.1V lokacin da kayan lantarki mara kyau shine carbon.Ga baturi iri ɗaya, ko da ƙarfin wutar lantarki na farko ya bambanta yayin caji, lokacin da ƙarfin baturi ya kai 100%, ƙarfin lantarki na ƙarshe zai kai matakin daidai.A yayin da ake yin cajin baturin lithium-ion, idan wutar lantarki ta yi yawa, za a samu zafi mai yawa a cikin baturin, wanda zai lalata ingantaccen tsarin lantarki na baturin ko kuma ya haifar da gajeriyar kewayawa.Don haka, ya zama dole a saka idanu akan ƙarfin cajin baturi yayin amfani da baturi don sarrafa ƙarfin lantarki a cikin kewayon ƙarfin lantarki da aka yarda.
2. Yanzu.Tsarin caji yana buƙatar sarrafa cajin halin yanzu.Ana ƙayyade ƙarfin halin yanzu na baturin ta hanyar girman ƙarfin baturin.Alamar iya aiki ta suna C, kuma naúrar ita ce "Ah".Hanyar lissafin ita ce: C = IT (1-1) A cikin dabarar, ni ne kullun fitarwa na yanzu, kuma T shine lokacin fitarwa.Misali, don cajin baturi mai ƙarfin 50Ah tare da halin yanzu na 50A, yana ɗaukar awa 1 don cikakken cajin baturin.A wannan lokacin, adadin cajin shine 1C, kuma yawan cajin da aka saba amfani dashi shine tsakanin 0.1C da 1C.Gabaɗaya magana, tsarin caji ya kasu kashi uku: jinkirin caji (wanda ake kira trickle charging), caji mai sauri da caji mai sauri gwargwadon ƙimar caji daban-daban.A halin yanzu na jinkirin caji yana tsakanin 0.1C da 0.2C;cajin halin yanzu na caji mai sauri ya fi 0.2C amma ƙasa da 0.8C;cajin halin yanzu na caji mai sauri ya fi 0.8C.Tunda baturin yana da takamaiman juriya na ciki, dumama na ciki yana da alaƙa da halin yanzu.Lokacin da yanayin aiki na baturin ya yi girma sosai, zafinsa zai sa yanayin zafin baturin ya zarce ƙimar da aka saba, wanda zai shafi amincin baturin har ma ya haifar da fashewa.A farkon matakin caji, ko da baturin ya yi zurfi sosai, ba za a iya cajin shi da babban halin yanzu ba.Kuma yayin da caji ke ci gaba, ƙarfin baturi na karɓar halin yanzu yana raguwa daidai.Don haka, yayin aiwatar da cajin baturi, dole ne a sarrafa cajin halin yanzu gwargwadon takamaiman yanayin baturin.
