Ka'idar cajin Lithium da fitarwa & ƙirar hanyar lissafin wutar lantarki

2.4 Mitar wutar lantarki mai ƙarfi algorithm

Algorithm mai ƙarfi mai ƙarfi coulometer na iya ƙididdige yanayin cajin baturin lithium kawai bisa ga ƙarfin baturi.Wannan hanyar tana ƙididdige haɓaka ko raguwar yanayin caji bisa ga bambanci tsakanin ƙarfin baturi da ƙarfin buɗewar baturi.Bayanin ƙarfin lantarki mai ƙarfi na iya yin daidai da halayen baturin lithium, sannan ƙayyade SOC (%), amma wannan hanyar ba za ta iya ƙididdige ƙimar ƙarfin baturi (mAh).

Hanyar lissafinsa ta dogara ne akan bambancin ƙarfin baturi da ƙarfin lantarki na buɗewa, ta hanyar amfani da algorithm na jujjuya don ƙididdige kowane karuwa ko raguwa na yanayin caji, don kimanta yanayin cajin.Idan aka kwatanta da maganin auna ma'aunin coulomb, ƙarfin ƙarfin ƙarfin ƙarfin lantarki coulometer ba zai tara kurakurai tare da lokaci da na yanzu ba.Coulometric coulometer yawanci yana da ƙarancin ƙididdige ƙimar yanayin caji saboda kuskuren fahimtar halin yanzu da fitar da baturi.Ko da kuskuren ji na yanzu yana da ƙanƙanta, ma'aunin coulomb zai ci gaba da tara kuskuren, kuma za a iya kawar da kuskuren da aka tara kawai bayan cikakken caji ko cikakken fitarwa.

Algorithm na ƙarfin lantarki mai ƙarfi Mitar wutar lantarki tana ƙididdige yanayin cajin baturin kawai daga bayanin ƙarfin lantarki;Domin ba a ƙididdige shi da bayanan baturi na yanzu, ba zai tara kurakurai ba.Don inganta daidaiton yanayin caji, ƙarfin ƙarfin lantarki algorithm yana buƙatar amfani da ainihin na'ura don daidaita ma'auni na ingantaccen algorithm bisa ga ainihin madaidaicin ƙarfin baturi a ƙarƙashin yanayin cikakken caji da cikakken fitarwa.

Hoto 12. Ayyukan ƙarfin lantarki mai ƙarfi algorithm mita lantarki da samun haɓakawa

Mai zuwa shine aikin algorithm mai ƙarfi a ƙarƙashin ƙimar fitarwa daban-daban.Ana iya gani daga adadi cewa yanayin cajin daidaiton sa yana da kyau.Ko da kuwa yanayin fitarwa na C/2, C/4, C/7 da C/10, kuskuren SOC na wannan hanya bai wuce 3%.

Hoto 13. Halin da ake cajin algorithm mai ƙarfi mai ƙarfi a ƙarƙashin ƙimar fitarwa daban-daban

Hoton da ke ƙasa yana nuna yanayin cajin baturin a ƙarƙashin yanayin gajeriyar caji da gajeriyar fitarwa.Kuskuren halin caji har yanzu ƙanƙanta ne, kuma mafi girman kuskuren shine kawai 3%.

Hoto 14. Halin cajin ƙarfin ƙarfin lantarki mai ƙarfi a cikin yanayin gajeriyar caji da gajeriyar fitarwa na baturi

Idan aka kwatanta da coulomb metering coulometer, wanda yawanci ke haifar da rashin daidaiton yanayin caji saboda kuskuren fahimtar halin yanzu da fitar da baturi, algorithm mai ƙarfi ba ya tara kuskure tare da lokaci da na yanzu, wanda shine babban fa'ida.Saboda babu caji/fitarwa bayanin halin yanzu, ƙarfin ƙarfin ƙarfin lantarki algorithm yana da ƙarancin ɗan gajeren lokaci da jinkirin amsawa.Bugu da ƙari, ba zai iya ƙididdige cikakken ƙarfin caji ba.Koyaya, yana aiki da kyau cikin daidaito na dogon lokaci saboda ƙarfin baturi zai nuna yanayin cajin sa kai tsaye.
