The Inspiration from Why Electric Bicycles Are Prone to Catching Fire

Electric bicycles occasionally catch fire. Shanghai Leiditech’s EMC Brother analyzes the reasons, which may provide some inspiration for you.

The reason why electric bicycles are prone to catching fire may be due to insufficient protection functions of the battery management system (BMS) or battery quality issues. To enhance the BMS protection functions and reduce the risk of fire, consider the following points:

Battery quality control: Select high-quality battery suppliers, and strictly control raw materials and production processes to ensure the safety and stability of batteries.

Overcharge and discharge protection: The BMS needs an accurate overcharge and discharge protection function to prevent the battery from overheating or even catching fire due to improper charging and discharging. Consider adopting more advanced voltage and temperature monitoring technologies to cut off the charging and discharging circuit in a timely manner.

Temperature monitoring and control: The BMS should be able to monitor the battery temperature in real-time and take protective measures when the temperature exceeds the safe range, such as stopping charging/discharging or reducing the charging/discharging rate.

Short circuit protection: Strengthen the monitoring and protection against short circuits to ensure that the circuit can be cut off promptly in case of an internal short circuit in the battery, thus avoiding fire risks.

Overload protection: The BMS should be able to promptly detect and handle battery overload conditions to prevent battery damage caused by prolonged high-load operation.

Through the above improvements, the safety of electric bicycles can be enhanced, and the risk of fire can be reduced. Meanwhile, users should also pay attention to reasonable use and charging in daily use, avoiding over-discharging and over-charging to ensure the safety of electric bicycles.
