Nkhani - Zolakwa 5 Zofunika Kwambiri mu Kupanga Mabatire a Lithium Opangidwa ndi DIY Zomwe Zikuika BMS Pangozi

Kupanga mabatire a lithiamu a DIY kukukopa chidwi cha okonda komanso amalonda ang'onoang'ono, koma mawaya osayenerera a waya angayambitse zoopsa zazikulu—makamaka pa Battery Management System (BMS). Monga gawo lalikulu la chitetezo cha mapaketi a mabatire a lithiamu, BMS imayang'anira kuyitanitsa, kutulutsa, ndi chitetezo cha short-circuit. Kupewa zolakwika zomwe zimachitika kawirikawiri ndikofunikira kwambiri.kuonetsetsa kuti BMS ikugwira ntchito bwino komanso kuti chitetezo chonse chikhale chotetezeka.

Choyamba,kubweza ma P+/P- connections (mlingo wa chiopsezo: 2/5)imayambitsa ma circuit afupi polumikiza ma load kapena ma charger. BMS yodalirika imatha kuyambitsa chitetezo cha ma circuit afupi kuti iteteze batri ndi zida, koma milandu yoopsa imatha kuyatsa ma charger kapena ma load onse.Chachiwiri, kuchotsa mawaya a B musanayambe kugwiritsa ntchito njira yoyesera (3/5)Poyamba zimawoneka ngati zikugwira ntchito, chifukwa mawerengedwe a magetsi amaoneka abwinobwino. Komabe, mafunde akuluakulu amabwerera ku dera la BMS la sampling, zomwe zimawononga harness kapena internal resistor. Ngakhale mutagwirizanitsanso B-, BMS ikhoza kukhala ndi zolakwika zambiri za magetsi kapena kulephera—nthawi zonse lumikizani B- ku batri yoyamba ndi negative.

Chachitatu, kutsata kolakwika kwa harness (4/5)imawonjezera mphamvu ya BMS's voltage detection IC, kuyatsa ma sampling resistor kapena ma AFE chips. Musanyoze dongosolo la waya; limakhudza mwachindunji magwiridwe antchito a BMS.Chachinayi, kubweza ma polarities onse a harness (4/5)zimapangitsa kuti BMS isagwire ntchito. Bolodi likhoza kuoneka ngati lili bwino koma limatentha kwambiri mofulumira, ndipo mayeso ochaja/kutulutsa magetsi opanda chitetezo cha BMS angayambitse ma short circuits oopsa.

Cholakwika chachikulu kwambiri ndi kusinthana ma B-/P- connections (5/5).Chida cha BMS cha P-terminal chiyenera kulumikizana ndi negative ya load/charger, pomwe B- chikugwirizana ndi negative yayikulu ya batri. Kubwerera kumeneku kumaletsa chitetezo cha overcharge, over-discharge, ndi short-circuit, zomwe zimapangitsa batri ku mafunde osalamulirika komanso moto womwe ungachitike.

Ngati pali zolakwika zilizonse, chotsani nthawi yomweyo. Mangani mawaya molondola (B- ku batire yoyipa, P- kuyika/chaja yoyipa) ndikuyang'ana BMS kuti ione ngati yawonongeka. Kuyika patsogolo njira zoyenera zoyikira sikuti kumangowonjezera nthawi ya batire komanso kumachotsa zoopsa zosafunikira zokhudzana ndi chitetezo zomwe zimachitika chifukwa cha ntchito yolakwika ya BMS.
