High-accuracy battery simulator

BMS testfor electric vehicles

The Battery Cell Simulator is the core element of every BMS test system. Each module contains 12 virtual battery cells that electrically simulate real cells in electric vehicles. All of their properties can be parameterized and can therefore provide the battery management system with all the necessary states at cell level in a highly precise and dynamic manner. Static tests can be performed for extensive validation of balancing algorithms and security mechanisms, including combinatorics of multiple errors. In addition, dynamic tests are possible using integrated, differently parameterized comemso battery models on each cell or already connected Matlab models. With the dynamic tests, the state of charge (SOC), state of health (SOH) and history (log book) functions of the BMS can be checked. The electrical emulation of virtual battery cells not only enables the user to carry out extensive, but also safe, reproducible and fully automatic tests of the BMS. With the open interface for various software tool chains, comemso offers flexible options for different customer needs and powerful, ready-to-use test systems with very short training times.
