Any functions can be choose as follow:
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) Bluetooth function ,then you can check the batteries status by your phone
Other Advantage:
Detect and protect the battery from over-charge ,over-dicharge, over-current short-circuit
,temperature detecting protection and auotmatically voltage balance function .
Build with high end electronic components (High End IC and MOSFET ) ,simple structure
design will let it have more stable quality working performance , Flexible application ( it can be used for less
series battery by leaving some connection pins at empty status ),full set of protection measures let it works well
without any infulence from external unexpected accidents.
