Advanced Battery Management Systems for Electric Mobility

Detailed overview of innovation with sample startups and prominent university research


What it is

An Advanced Battery Management System (BMS) is a complex electronic system responsible for monitoring, controlling, and protecting a battery pack. It acts as the interface between the battery and the vehicle, ensuring optimal operation, safety, and maximizing battery lifespan.

Impact on climate action

The implementation of Advanced Battery Management Systems for Electric Mobility significantly enhances the sustainability of electric vehicles by optimizing battery performance and prolonging lifespan. This innovation reduces carbon emissions, improves energy efficiency, and fosters widespread adoption of electric mobility, thus accelerating global efforts towards combating climate change.

Underlying
Technology

  • Sensing and Monitoring: A BMS continuously monitors key battery parameters, such as voltage, current, temperature, and state of charge (SOC). This data is collected from sensors embedded within the battery pack and transmitted to the BMS for analysis.
  • Control and Optimization: Based on the sensor data, the BMS actively controls the charging and discharging processes, ensuring safe operating limits are maintained and battery performance is optimized. It also balances individual cells within the battery pack, preventing overcharging or over-discharging of any cell, which can lead to degradation or failure.
  • Safety and Protection: The BMS plays a critical role in protecting the battery from harmful conditions. It monitors for abnormal temperatures, overcurrents, and other potential hazards, triggering safety mechanisms like disconnecting the battery or limiting charging currents to prevent damage.
  • Communication and Diagnostics: The BMS communicates with the vehicle’s other systems, providing real-time battery information to the driver and enabling remote diagnostics and maintenance. It also stores historical battery data for analysis and optimization purposes.
