“BMS” on an e-bike battery stands for “Battery Management System,” which is an electronic circuit board that monitors and regulates the voltage and current of each individual cell within the battery pack, ensuring safe and efficient charging and discharging by preventing overcharging, over-discharging, and overheating, ultimately extending the battery life of the e-bike. 

Key points about BMS in e-bike batteries:

Impact on performance: By managing individual cell health, a BMS can optimize the battery’s lifespan and overall performance. 

Function:It monitors the voltage of each cell within the battery pack, balancing them to ensure they all charge and discharge evenly. 

Safety features:A BMS will cut off power to the motor if it detects unsafe conditions like excessive voltage, current, or temperature.
