3S PCB / PCM- Keeppower XZD-3S1550 (protection electronics)

BMS battery management system - PCB protection circuit for three Li-ion battery cells (Made in Japan). A battery management system (BMS) is an electronic circuit which, ie a monitoring and control of a rechargeable battery storage battery system used. The need for a BMS arises when several battery cells are interconnected to form a battery. The BMS should recognize, monitor and correct the inevitable manufacturing-related variations in various parameters of the battery cells, such as capacity and leakage currents. Electronics not suitable for tools / Powertoll area.

Application: Li-ion battery packs

Note: After soldering, the protective circuit in the battery pack must be activated, this is done by briefly charging the electronics.

Connection diagram:

B- = battery minus B + = battery plus BM = battery connection plus / minus (for checking the individual cells) P- = loading, unloading / input / output minus P + = loading, unloading / input / output plus You can view the data sheet here:
