1S PCB/PCM- Keeppower XZD-YH10AC (Protection Electronics).
BMS (Battery Management System) – PCB Protection Circuit for a Li-Ion Rechargeable Cell (Made in Japan). A Battery Management System (BMS) is an electronic circuit used to monitor and control a rechargeable battery system, i.e. a accumulator system is used. The necessity of a BMS arises when several accumulator cells are interconnected to form a battery. The BMS is intended to detect, monitor and adjust the unavoidable production-related variations of various parameters of the accumulator cells, such as capacity and leakage currents.
Application: Li-ion battery packs
Note: After soldering the protection circuit in the battery pack must be activated, this is done by a short charging by the electronics.
Wiring diagram:
B- = Battery minus
B+ = Battery Plus
BM = Battery connection plus/minus (to check the individual cells)
P- = Charge, discharge/input/output minus
P+ = Charge, discharge/input/output plus
