What is a Battery Management System and How Does it Work?

The way an engine is the heart of a petrol-powered motorcycle, the battery is the heart of an electric motorcycle. Every cell inside the battery behaves differently. Every cell needs to be managed differently and properly to ensure that the battery keeps performing efficiently over the years. This is why the battery management system in electric bikes is such a crucial component.

In the following blog post, we will be going through the basic definition of a battery management system (BMS) and how it works in detail.

What is a BMS?

The BMS in an electric motorcycle is system that monitors the battery. It keeps the battery in check 24/7 and solves issues immediately. It is like the brain of an electric motorcycle. Today, electric motorcycles either run on a lithium-ion battery or an LFP battery (Lithium Iron Phosphate). These batteries are powerful and efficient, but they need to be monitored constantly by a BMS to ensure peak performance.

Every cell in the battery works within a voltage range, and it is the BMS’s responsibility to keep them within that range at all times. The BMS also monitors the temperature of the battery and keeps it under control. Every cell in the battery ages differently, so BMS for EV bikes balances them out to keep the battery running efficiently.

How Does a BMS Work?

This is how a BMS works in an electric motorcycle:

• The BMS monitors the voltage of each cell, and whenever the battery is about to reach the upper limit, it pulls back the current to prevent damage.
• The BMS detects whenever the temperature is about to rise and brings it back to a safe range before it damages the battery.
• Not all cells degrade at the same rate. The BMS shifts current between cells to keep the battery running efficiently.
• The BMS is responsible for stopping the charging as soon as the battery is fully charged to avoid overheating.
• The BMS catches any short circuit and cuts it immediately before it reaches the battery.

Conclusion

The BMS is the most important component of an electric motorcycle and should be immediately fixed whenever it breaks down to avoid damage to other components. You can explore AVORE BMS before you visit your local EV two-wheeler dealership.
