Battery Management System Testing Solution

Whether you are working on battery systems for mobile or stationary applications, we offer powerful solutions for testing the battery management systems required for state-of-the-art batteries, both on the signal level and on the high-voltage level. With their outstanding performance and precision, our BMS test systems can be used for various applications in different industries and can support you in validating the functionality of cutting-edge battery management systems, while enabling you to be well-prepared for future challenges. With an overall system voltage of up to 1,500 V, our modular and finely-scalable test solution can be tailored to any kind of battery system.

dSPACE Solutions for BMS Testing on the Signal Level

Testing a BMS on the signal level means testing its main functions and its interaction with the vehicle network without using high voltages. For this purpose, the battery cells and the cell supervision circuits (CSCs) are simulated.

For the simulation of CSCs and additional components, such as current sensors, you can use our SCALEXIO real-time hardware. Especially for the communication between the simulated CSCs and the device under test (DUT), our test systems support a wide range of communication interfaces, including CAN, SPI, isoSPI, UART, and I²C.

dSPACE Solutions for BMS Testing on the High-Voltage Level

Testing a BMS on the high-voltage level means testing the complete BMS, including one or all CSC modules. This kind of testing is essential for release and acceptance tests, and highly relevant for the automotive-specific functional safety standard ISO 26262.

For testing battery management systems on the high-voltage level, we provide powerful test systems that emulate all inputs of the BMS. This includes all battery cell voltages, temperature sensors, and the battery current as well as all signals coming from the various high-voltage sensors in the vehicle, e.g., the sensors at the inverter, the battery, or the charging point.
