 JBD-AP21S001 is a software protection board solution designed specifically for 6-21 battery packs such as electric motorcycles, small three-wheels, small four-wheels, etc. It can be applied to lithium batteries with different chemical properties, such as lithium ion, lithium polymer, and iron phosphate. Lithium etc. The whole system uses Panasonic's front-end acquisition chip + MCU, and an external communication port. 

● 6-21 series battery cell series protection.                                                               

●The battery is intelligently balanced, and the balanced opening voltage and pressure difference can be flexibly adjusted by the host computer. Optional charge balance or static balance. Through time-sharing equalization, the maximum equalization current can reach 200mA.                                                                                                           

● Integrate hardware protection functions such as overvoltage, undervoltage, overcurrent, and short circuit.                                                                                        

 ● Multiple working modes, when the protection board is in a static state, it can delay to enter dormancy to achieve the purpose of reducing power consumption.       

 ●The default three-channel temperature detection probe, one channel detects the internal temperature of the protection board, and the two channels are placed in the place where the temperature needs to be detected according to customer needs.     

● Multiple external expansion interfaces can be used to add CAN\RS232 communication, charging low-temperature heating, secondary protection (FUSE), charger ID identification resistance, LED power display and other functions through the expansion interface.
