Efficient modelling of heterogeneous battery management systems

A simulation environment for the design of battery management systems (BMS) based on the modelling languages SystemC/SystemC AMS will be presented. Models of battery cells, the temperature and current sensors, the components for balancing of the battery cells, the integrated circuits to monitor the cell voltages and the interface for the data transmission to the controller where the BMS software is running describe the hardware. The software can be integrated via an AUTOSAR RTE compliant application programming interface into the simulation. The approach allows considering the nominal as well as the faulty behaviour of components. The simulation environment is integrated into the design environment COSIDE
