Developing and testing battery management systems for electric vehicles

Powerful, innovative batteries which allow for long ranges and rapid charging while meeting the highest safety requirements are key for the final breakthrough of electric vehicles. This applies to electric cars as well as electric aircraft, trains, and off-highway vehicles.

To ensure safe and efficient operation and long-term vitality of the battery over thousands of charging cycles, all of these battery-electric vehicles (BEVs) need a battery management system (BMS). With our solutions, we offer comprehensive support for BMS development and testing to manufacturers all over the world.

BMS for Stationary Battery Systems

With the transition to renewable energies, stationary battery storage systems are becoming increasingly important, especially for private households. Like mobile battery systems, these systems require a BMS to ensure safe, reliable, and long-lasting operation of the individual battery cells. Of course, you can rely on our full support when developing and testing these systems.

Challenges

Challenges

The BMS must handle various tasks, including:

  • Voltage, temperature, and overall current measurement
  • Thermal management
  • Balancing the level of charging for the individual cells
  • Operating safety routines
  • Calculating the state of charge (SOC) and the state of health (SOH) of the battery

Future challenges for BEVs and their battery management systems include the bidirectional energy transfer to stabilize the power grid by using the vehicle battery as a kind of mobile storage system, a concept better known as vehicle-to-grid (V2G) systems.

dSPACE Solutions for Battery Management Systems

Are you developing battery management systems (BMS) or related technologies? We offer the right tools to improve your development process while increasing the quality and maturity of the BMS before it goes into mass production. Depending on the device under test, ranging from a complete BMS to individual cell supervision circuits (CSC) which monitor and balance voltages at cell level, our various software and hardware products cover testing on the signal level as well as on the high-voltage level. However, our comprehensive portfolio of solutions also supports you earlier in the development process, for example in prototyping BMS functions or in generating highly efficient production code for BMS to allow for early verification of BMS algorithms. Just ask us.
