Abstract :
The life time of the battery depends of many different parameters. One parameter set is the internal battery parameters which are influenced by the battery manufacturers, and the second set is the external battery parameters which are influenced by the battery users. The external parameter can have an enormous influence on the life time. By use of a battery management system (BMS) it is possible to control the external parameters with the target to extend battery lifetime. This paper describes a BMS consisting of a data acquisition system, battery state calculation, electrical management, thermal management, safety/supervisory management, and communication. If the functions of a BMS are optimized to the used battery type and application, it is possible to extend battery lifetime
