How BMS Prevents Overcharging, Over-discharging, and Short Circuits in Electric Bicycle Batteries

Battery Management System (BMS) is the core of electric bicycle battery safe operation, preventing overcharging, over-discharging, and short circuits through real-time monitoring and protection mechanisms.

Prevention Mechanisms

Preventing Overcharging: BMS monitors individual cell voltage; when reaching upper limits (like 4.2V/cell), cuts charging circuit. Uses balancing technology (active or passive) to balance cell voltages, preventing partial overcharging.

Preventing Over-discharging: BMS detects battery pack voltage; if below safety threshold (2.5V-3.0V/cell), disconnects discharge circuit. Provides low-power warnings, reminding users to charge promptly.

Preventing Short Circuits: Uses high-precision current sensors (like Hall sensors) detecting abnormal currents. When short circuits occur (within 250-500μs), triggers protection mechanism cutting circuits.

Additional Protection: Monitors temperature preventing overheating-induced thermal runaway. Supports fault diagnosis, recording abnormal data for troubleshooting.

Why is BMS Protection Crucial?

BMS reduces battery fire or explosion risks through multiple protection mechanisms, extends battery life, and ensures riding safety. For example, 48V lithium batteries can safely operate 800-2000 cycles under BMS protection.
