What is battery management system (BMS) in electric vehicles?
The Battery Management System (BMS) in electric vehicles (EVs) plays a vital role in managing the battery’s performance, safety, and longevity. It monitors crucial aspects like voltage, temperature, and cell balance, ensuring the battery operates within safe limits.
Why do EV batteries need a BMS?
A battery (lithium ion battery) used in an EV deteriorates every time the battery discharges or is charged. These cycles of battery deterioration may lead to a drop in the vehicle performance. The BMS is an important solution to this problem.
How does a battery management system (BMS) work?
The BMS monitors the temperature of the battery pack, ensuring it stays within an optimal range (typically between 20°C and 40°C). If the temperature exceeds safe limits (e.g., above 45°C), the BMS may activate cooling systems or stop charging to prevent damage or thermal runaway. 6. Charging and Discharging Control
How will BMS technology change the future of battery management?
As the demand for electric vehicles (EVs), energy storage systems (ESS), and renewable energy solutions grows, BMS technology will continue evolving. The integration of AI, IoT, and smart-grid connectivity will shape the next generation of battery management systems, making them more efficient, reliable, and intelligent.
How does a battery management system work?
The BMS constantly monitors the temperature of the battery through a temperature sensor. Using the battery within a proper temperature range ensures the safety of the battery and longer service life. Control：The BMS eliminates variations in performance of individual battery cells to allow them to work uniformly.
How does a BMS monitor a battery?
The battery’s voltage, current, temperature, and SOC are all constantly monitored by the BMS. To evaluate the battery's performance and condition, this information is essential. As an example, the SOC, which measures the battery’s remaining charge, has a direct impact on the EV's driving range.
