Electric vehicles have comparatively high purchase cost due to the still very expensive energy storage. The energy storage is subject to various aging effects that lead to a complicated life forecast and therefore difficult calculation of the loss in value due to lack of experience. Simultaneously, a change in the mobility infrastructure is becoming apparent due to increasing urbanization. A further development in the handling of damages and risk assessment for electric vehicles is therefore essential.

In addition to considering the characteristics of the customers use of electrical energy storage devices and their damage assessment a general condition assessment will be developed. Key point is the depth analysis of the energy storage, including the associated battery system technology. Besides the impact of crash situations, extreme climatic conditions and operating errors also unauthorized changes are taken into account.

Currently, the analysis and development of the functions of the battery management system takes place, one of the most important elements in the storage system. It is used to monitor and protect the energy storage as well as identifying related parameters.

The primary objective is the development and optimization of detection and response strategies for manipulation and tuning as well as critical faults in the entire electric storage system. For this purpose, special test benches are used with those also safety-critical scenarios can be safely examined beyond the limit range.
