Lokacin haɗa fakitin batirin lithium, zaɓar Tsarin Gudanar da Baturi da ya dace (BMS, wanda aka fi sani da allon kariya) yana da matuƙar muhimmanci. Abokan ciniki da yawa suna tambaya:
"Shin zaɓar BMS ya dogara ne akan ƙarfin batirin?"
Bari mu binciki wannan ta hanyar misali mai amfani.
Ka yi tunanin kana da motar lantarki mai ƙafa uku, wacce ke da iyakar ƙarfin lantarki na 60A. Kana shirin gina fakitin batirin LiFePO₄ na 72V, 100Ah.
To, wane BMS za ku zaɓa?
① BMS na 60A, ko ② BMS na 100A?
Ɗauki ƴan daƙiƙa kaɗan don tunani…
Kafin mu bayyana zaɓin da aka ba da shawarar, bari mu yi nazari kan yanayi biyu:
- Idan batirin lithium ɗinku ya keɓe ne kawai ga wannan motar lantarki, sannan zaɓar BMS 60A bisa ga iyakokin yanzu na mai sarrafawa ya isa. Mai sarrafawa ya riga ya iyakance jan da ake yi a yanzu, kuma BMS galibi yana aiki azaman ƙarin Layer na kariya daga overcurrent, overcharging, da overloading.
- Idan kuna shirin amfani da wannan fakitin batirin a aikace-aikace da yawa a nan gaba, inda za a iya buƙatar ƙarin wutar lantarki, yana da kyau a zaɓi babban BMS, kamar 100A. Wannan yana ba ku ƙarin sassauci.
Daga mahangar farashi, BMS 60A shine zaɓi mafi araha kuma mai sauƙi. Duk da haka, idan bambancin farashi bai yi yawa ba, zaɓar BMS mai ƙimar halin yanzu mafi girma zai iya samar da ƙarin dacewa da aminci don amfani a nan gaba.
A ka'ida, matuƙar ƙimar ci gaba da BMS na wutar lantarki ba ta ƙasa da iyakar mai sarrafawa ba, abin karɓa ne.
Amma shin ƙarfin baturi har yanzu yana da mahimmanci ga zaɓin BMS?
Amsar ita ce:Eh, babu shakka.
Lokacin da ake saita BMS, masu samar da kayayyaki yawanci suna tambaya game da yanayin nauyin ku, nau'in tantanin halitta, adadin igiyoyin jerin (ƙidayar S), kuma mafi mahimmanci,jimlar ƙarfin baturiWannan saboda:
✅ Kwayoyin halitta masu ƙarfi ko masu ƙarfi (masu ƙarfin C) gabaɗaya suna da ƙarancin juriyar ciki, musamman idan aka haɗa su a layi ɗaya. Wannan yana haifar da ƙarancin juriyar fakiti gaba ɗaya, wanda ke nufin mafi girman yuwuwar kwararar wutar lantarki ta gajere.
✅ Domin rage haɗarin irin wannan babban kwararar ruwa a cikin yanayi marasa kyau, masana'antun galibi suna ba da shawarar samfuran BMS waɗanda ke da ɗan ƙaramin matakin kwararar ruwa.
Saboda haka, ƙarfin aiki da kuma yawan fitar da ƙwayoyin halitta (C-rate) muhimman abubuwa ne wajen zaɓar BMS mai kyau. Yin zaɓi mai kyau yana tabbatar da cewa batirinka zai yi aiki lafiya kuma cikin aminci tsawon shekaru masu zuwa.
