The battery management system is designed according to the customer’s specifications using standardised and tested computer modules and periphery modules for current, voltage, temperature and isolation measurements. The modular design makes it possible to flexibly utilise redundancies to ensure the highest level of safety. High-performance computers also make it possible to apply complex algorithms to determine the charging and cell states and monitor the current, voltage and temperature as well as other functions. The system meets all of the approval requirements under the most stringent environmental conditions. Due to its simple design, it can be scaled up for use with any cell configuration.
