BMS for Lithium Battery

 JBD-HP28SA is designed by Dongguan jiabaida Electronic Technology Co., Ltd. It is an intelligent protection board scheme specially designed for 28 series battery packs of electric bicycles and motorcycles. It is suitable for lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc.The protection board has strong load carrying capacity and the maximum continuous discharge current can reach 100A

1. 3-28 cell series protection

2. Various protection functions for charging and discharging

3. Hardware discharge over - current, short - circuit protection function processing

4.Reserve discharge control switch and discharge temperature protection position

5.Very low static consumption current

6. With equalization function

Operating voltage range:10-14.6V
Operating current (MAX): 120A
Over-charge protection voltage: 3.65±0.05V
Over-discharge protection voltage:2.5±0.1V
Temperature protection value of charging: 75℃

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 time 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 going 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 time 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 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.
