Sisitemu yo gucunga bateri (BMS)igira uruhare runini mugukora neza kandi neza imikorere ya bateri ya lithium-ion, harimo LFP na batteri ya lithium (NCM / NCA). Intego yacyo yibanze nugukurikirana no kugenzura ibipimo bitandukanye bya batiri, nka voltage, ubushyuhe, nubu, kugirango bateri ikore mumipaka itekanye. BMS irinda kandi bateri kutarenza urugero, gusohora cyane, cyangwa gukorera hanze yubushyuhe bwiza. Muri paki ya bateri hamwe nuruhererekane rwinshi rwa selile (imirongo ya batiri), BMS icunga kuringaniza selile. Iyo BMS inaniwe, bateri isigara ifite intege nke, kandi ingaruka zirashobora kuba mbi.
1. Kurenza urugero cyangwa Kurenza urugero
Imwe mumikorere ikomeye ya BMSis kugirango ibuze bateri kurenza urugero cyangwa gusohora cyane. Kwishyuza birenze urugero ni bibi cyane kuri bateri zifite ingufu nyinshi cyane nka lithium ya ternary (NCM / NCA) kubera ko ishobora guhura nubushyuhe bwumuriro. Ibi bibaho iyo voltage ya bateri irenze imipaka itekanye, ikabyara ubushyuhe burenze, bushobora gutera guturika cyangwa umuriro. Kurenza urugero, kurundi ruhande, birashobora kwangiza burundu selile, cyane cyane muriBatteri ya LFP, irashobora gutakaza ubushobozi no kwerekana imikorere mibi nyuma yo gusohoka cyane. Muri ubwo bwoko bwombi, kunanirwa kwa BMS kugenga voltage mugihe cyo kwishyuza no gusohora bishobora kwangiza bidasubirwaho paki ya batiri.
2. Ubushyuhe bukabije nubushyuhe bwo guhunga
Batteri ya lithium ya Ternary (NCM / NCA) yunvikana cyane nubushyuhe bwo hejuru, cyane kuruta bateri ya LFP, izwiho kuba ihagaze neza. Nyamara, ubwo bwoko bwombi busaba gucunga neza ubushyuhe. BMS ikora ikurikirana ubushyuhe bwa bateri, ikemeza ko iguma mumutekano muke. Niba BMS inaniwe, ubushyuhe burashobora kubaho, bigatera urunigi ruteye akaga rwitwa ubushyuhe bwo guhunga. Mu ipaki ya batiri igizwe nuruhererekane rwinshi rwa selile (imirongo ya batiri), guhunga ubushyuhe birashobora gukwirakwira vuba kuva selile imwe kugeza kurindi, biganisha ku gutsindwa gukabije. Kubisabwa na voltage nyinshi nkibinyabiziga byamashanyarazi, iyi ngaruka irakomera kuko ubwinshi bwingufu hamwe nimibare ya selile biri hejuru cyane, bikongerera amahirwe yingaruka zikomeye.
3. Ubusumbane hagati ya selile
Muri paki ya batiri-selile nyinshi, cyane cyane izifite ingufu za voltage nyinshi nkibinyabiziga byamashanyarazi, kuringaniza voltage hagati ya selile ni ngombwa. BMS ishinzwe kwemeza ko selile zose ziri mumapaki iringaniye. Niba BMS inaniwe, selile zimwe zishobora kwishyurwa mugihe izindi ziguma zishyuwe. Muri sisitemu ifite imirongo myinshi ya batiri, uku kutaringaniza ntigabanya gusa imikorere muri rusange ahubwo binatera umutekano muke. Ingirabuzimafatizo zirenze urugero cyane zifite ibyago byo gushyuha cyane, zishobora kubatera kunanirwa bikabije.
4. Kunanirwa kw'ingufu cyangwa kugabanya imbaraga
BMS yananiwe irashobora kugabanya imikorere cyangwa no gutsindwa kwingufu zose. Hatabayeho gucunga neza voltage, ubushyuhe, hamwe no kuringaniza selile, sisitemu irashobora gufunga kugirango birinde kwangirika kwinshi. Mubisabwa aho imigozi ya batiri yumuriro mwinshi irimo, nkibinyabiziga byamashanyarazi cyangwa kubika ingufu zinganda, ibi bishobora gutakaza ingufu zitunguranye, bikagira ingaruka zikomeye kumutekano. Kurugero, ipaki ya batiri ya lithium irashobora gufungwa muburyo butunguranye mugihe ikinyabiziga cyamashanyarazi kigenda, bigatuma ibintu bigenda nabi.
