Evaluation of installation sites of stationary battery home storage systems

As part of the EMILAS project, VDE Renewables carried out an evaluation of the safety and reliability of charging stations for BEVs with second life battery storages. Possible locations for battery storage inside buildings were analyzed and their advantages and disadvantages were evaluated against each other. Four basic scenarios were considered as installation locations: Garage, technical room, separate battery room or external container.

The evaluation of the individual installation locations was analyzed and compared using various criteria with regard to their fire protection effectiveness, feasibility and cost-effectiveness.

Through expert interviews and a sound literature analysis, it was possible to determine that the same requirements apply to the design of the fire protection system for a Second Life storage system as for First Life battery storage systems. The general fire protection requirements for the installation site depend on a variety of factors. These should be included in the planning of the storage unit at an early stage to guarantee reliable implementation. Overall, it was found that all possible installation locations have certain advantages and disadvantages that need to be weighed up for the respective application.

As the EMILAS project is funded by the Federal Ministry for Economic Affairs and Climate Protection, the document is only published in German.

2nd Life Storage in Europe

Due to ageing, batteries lose part of their capacity in the course of their life. This reduces the range of a vehicle, for example and the battery no longer meets the requirements of the application. However, this does not have to be the end of the battery's life. With about 75% of its original capacity, this valuable resource can be given a second life as a stationary energy storage device instead of going straight into recycling.

In addition to the evaluation of the installation sites, a survey of stationary 2nd life storage facilities in Europe was carried out as part of the project. You can find the document in the download area on the top right side of this page.
