M A K 18V Battery Pcb Bms Accessories 1830 1840 Lithium Battery Protection Board

4S 20A Square 14.8V 16.8V BMS Battery Management System PCM PCB for 4 Series 18650 li-ion Lithium Ion Battery Pack

A BMS may protect its battery by preventing it from operating outside its safe operating area, such as:

• Over-current during charging

• Over-current during discharge

• Over-voltage during charging, especially important for lead–acid and Li-ion cells

• Under-voltage during discharging

• Over-temperature

• Charging while under temperature

• Over-pressure (NiMH batteries)

• Ground fault or leakage current detection (system monitoring that the high voltage battery is electrically disconnected from any conductive object touchable to use like vehicle body)

The BMS may prevent operation outside the battery's safe operating area by:

• Including an internal switch (such as a relay or mosfet) which is opened if the battery is operated outside its safe operating area

• Requesting the devices to which the battery is connected to reduce or even stop using or charging the battery.

• Actively controlling the environment, such as through heaters, fans, air conditioning or liquid cooling

bms 7s 10a for li ion battery with contact plate Specification(the data can be adjustment depends on your application):

Include contact plate very suitable for battery case ,widely use in power tool field:

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) Blue tooth function ,then you can check the batteries status by your phone
