Briefly description :
This battery BMS can monitor the single series cell voltage, charge and discharge current, and detect temperature of sampling place in real time, estimate the remaining power of the battery pack, and perform charge balance. BMS has such display function : Power amount ,working status ,abnormal working etc . BMS can communicate with external devices such as host computers, chargers, mobile phones with the help of external communication module to import parameters setting, receive commands. In the eventof meeting abnormal conditions such as (cell overvoltage, cell undervoltage, overtemperature, overcurrent), the BMS can send out an alarm message, and turn off the charging or discharging MOSFET to protect the battery pack from any possible damage. This BMS has switch and charging activation function. It is equipped with a serial communication host computer,which has the functions of monitoring real-time battery pack data and status, protection board controlling status, reading and writing, import and export of fault parameters, calibration, voltage and temperature comparison with basement criterions , and program upgrade. Supporting RS485 communication to realize RS485 communication between BMS and externaldevices .

10) Temperature rise during maximum discharge: less than 40℃
11) Charging balance current: not less than 50mA.
12) Power consumption: in normal working status: the current is less than 30mA.
During work off status : The current is less than 300uA.
13) The weak current switch supports start with load, wake up from sleep, and switch on and off.
14) 4 LED lights power display, 1 pcs of alarm light
15) With precharge and pre-discharge circuit to provide safer and reliable working performance for the BMS when it needs large current discharge and large current charge , the BMS will make sure the stable current supply
What Bluetooth Communication Module can do ?
What PC module can do ?
with the PC module it can allowed to set almost of the protection paramters .
For different series cell , the connection can be different in according to below instructions :
Our company is committed to improvement of quality and reliability, but in general, there will be a certain probability of failure in electrical components and parts, with different environment and conditions, the durability will be different. When in use, the lengthy design is adopted to avoid overload abnormal fever, smoking, and even casualty, fire accidents, social damage, etc.
Reminds : We will send the detail connection drawings to the client with this product if client needs and this BMS will includes all necessories connectors with wire to make sure client can connect it easily . please follow up it correctly to avoid of any mistake ,above connection is only for simple explaination purpose .
1)Do not apply the PCB which beyonds the specified criterias as above :
2)Sometime , the battery may not discharge when connected this PCB , please connect it to the charge and it can recover to the normal status .
3)The PCB may not work normarly When Mixing cells which were over-discharged or over-charged ,
4) Do not shock this PCB with big static even though the PCB has been designed with anti-stastic protection function.
