Description

The importance of reliable Battery Management Systems (BMS) for Lithium-Ion Batteries (LIB) has risen due to the development of electric mobility and the insertion of renewable energy into the electrical power grid. This makes development and testing of BMS an essential part of the development of grid and mobility related energy storages.
Testing a BMS with real battery cells requires considerable effort to control the condition of the single cells in terms of State Of Charge (SOC), temperature and State Of Health (SOH). Since it takes up to 24 hours for a battery cell to reach equilibrium after a current is switched off, setting an arbitrary battery state consumes a lot of time. Furthermore, testing safety functions with real battery cells becomes hazardous if the BMS fails. Active balancing schemes add complexity and high cell currents to the test scenario which adds to the safety concerns.
To overcome the concerns a BMS HIL was developed.
