Hardware component:

       This BMS has applied with high-quality IC chip especially for lithium battery protection purpose .highly detection precision degree on over-charge,over-discharge, voltage balancing, and with detection on wires disconnection functions, with three layers of over-discharge and over-current detections and delay times in detecting process.( Over-current 1,over-current 2, short circuit protection ) . short-circuit of charging port, with two layers protection against over-voltage when charging :

Protection parameters setting:

Over-charge protection voltage, Over-discharge protection voltage, Over-charge, and over-discharge release voltage, Battery series Setting on Software, etc ( this BMS can be adjusted by us for Max 30S Lithium or Lifepo4 Battery application, a client should not set by yourself without our instructions ).

Operation :

  With the APP software system to monitor the battery healthy visibly and conveniently, and some parameters even can be set via Bluetooth APP software.

Components included:

    With one Bluetooth module for the Android system only, 4.3Version Above . with wire and connector for the Battery and the software system of the mobile phone will be sent to the buyer, the client can buy the PC adapter separately if needs. And we can design and produce the battery protection circuit board according to the client's demand with certain reasonable order quantity.

Function:

Specification Reference:

 This parameter is just for reference, a buyer can set the protection parameters on the PC software without problems.

Protection function description:

Overcharge protection :

    When the battery is under the charging state, the voltage keeps going up. When the protection board detects that the voltage of any cell is higher than the overcharge protection value, the protection board will start timing immediately. When the timer reaches the overcharge protection delay, the protection board will turn off the charging MOS tube, at that time, it cannot be charged.

Overcharge protection recovery:

  After the overvoltage protection appears on the protection board, the battery voltage will go down under the static or discharge state of the battery. When the protection board detects that each voltage is lower than the recovery voltage of the overcharge protection, the protection board will output a signal and turn on the charging MOS tube to charge.

Over-discharge protection:

   When the battery is under the discharge state, the voltage keeps going down. When the protection board detects that the voltage of any cell is lower than the overcharge protection value, the protection board will start timing immediately. When the timer reaches the over-discharge protection delay, the output signal of the protection board will turn off the discharge MOS tube, the load lock circuit will work, but, it cannot discharge at this time.

Over-discharge protection recovery:

   After the over-discharge protection appears on the protection board, the battery voltage will be going up under the static or discharge state of the battery. When the protection board detects that each voltage is higher than the recovery voltage of the over-discharge protection. At this time, disconnect the load or charge, the protection board will output a signal and turn on the charging MOS tube to charge.

Overcurrent protection:

  When the battery is under the static or discharge state, the current suddenly increases. When the protection board detects that the current reaches the overcurrent protection value, the protection board will start timing at that time. When the current duration in the circuit reaches the overcurrent protection delay time, the output signal of the protection board will turn off the discharge MOS tube, and the load lock circuit will work. At this time, the discharge cannot be conducted. Overcurrent protection recovery: After the discharge overcurrent protection appears on the protection board, the discharge MOS tube is turned off, and the current in the loop becomes 0. At this time, the load is disconnected or charged, the output signal of the protection board will turn on the discharge MOS tube to discharge

PC software management:

    For these Modules, Our BMS will be equipped with Bluetooth Module and if you need the PC communication module, you can buy it separately and we will ship them together to you based on choice:

FAQ:

What Bluetooth Communication Module can do?

   With Bluetooth Communication Module, the APP Software can be connected, and all information of the BMS can display on your  Mobile Phone and you can set some parameters on Your APP software: Over-protection voltage, Over-discharge protection voltage Release voltage of over-charge and discharge.

What PC communication Module can do?

  With PC communication module, you can set some basic protection parameters the same with APP software ,and besides the setting scope, PC Module will be extended the parameters setting, such as battery series setting Cell's voltage calibration . some battery information input in according to the below pictures, client can choose the PC Communication module flexibly in according to your practical application purpose.
