LS76925+CS32F103C8T6 BMS protection solution

This BMS protection solution is based on Lingsiwei AFE LS76925 + Xinhai CS32F103C8T6 MCU control. MCU controls LS76928 to perform related battery pack management functions and protection, such as battery pack voltage, current, temperature measurement; charging, discharging, and pre-discharge FET tube and balance control. It can also communicate stably with external devices through the RS-485 bus interface. It can monitor 3~7 strings of batteries , including ternary lithium, lithium iron phosphate, and sodium ion. It is widely used in drones, outdoor power supplies, power tools and other fields.

 

This solution is applicable to various BMS protection scenarios:

u   Drones

u   Outdoor Power Supply

u   electrical tools

u   Cordless Vacuum Cleaner

u   Backup power or energy storage system
