10s bms 36v lithium ion battery bms with NTC charging voltage 42v 25a bms high temperature protection 20A
This BMS has applied with high quality IC chip specially for
lithium battery protection purpose .highly detection
precision degree on over-charge,over-discharge,voltage balancing
,and with detection on wires disconnection functions,
,with charging protection functions .
This is The PCB for 10 series 36V(42v) or 7S 24V (29.4V )lithium
ion battery pack with 25A constant discharge current
and rated 5A charging current .the charge and discharge port is
different. Size :Max 54*74mm
And we can design and produce Battery protection circuit board in
according to client’s demand with certain
Function:
1) Power off detection (It can be locked when removed the PCM from battery pack, to avoid safety accidents caused by users unauthorized disassembly or replacement)
2) MOS statistics of overtemperature protection times (it can lock up after N times overtemperature protection to avoid safety accidents caused by user overload)
3) Power on timing (it can lock up after N years running, it means we can design a lock time depends on the batteries service life, then the user can’t replace the batteries by themself)
4) Counting discharge times (It can design lock up after N times charge and discharge, then if can’t be work end of batteries service life )
5) Add buzzer (it can make a sound to remind the user to charge when the battery is stored for a long time, the voltage is too low due to self discharge to protect batteries)
6) Unique ID (a unique ID number can be added to each board for product tracing)
7) UART communication (communication with PC can be realized, to setting and viewing the data of the above items 1-6 before delivery)
8) Blue tooth function ,then you can check the batteries status by your phone
