ELSA - Stationary usage of second hand li-ion batteries from electric vehicles

ELSA is an electrical lithium-ion storage assembled using 2nd life electrical vehicle (EV) batteries for stationary application in buildings.

By integrating second life car batteries and an Intelligent Energy Management System, a wide range of applications can be used. It can balance electricity demand and local PV generation (i.e. commercial buildings and farms). In charging stations, it can shave load peaks of high demand and balance times of high generation. The storage can be less expensive than a storage with new batteries all while delivering the same services for stationary storage. Distribution system operators (DSOs) can use it in sub-stations for frequency and power regulation.

Key features

  • Scalable solution.
  • Can provide multiple services to buildings and grids.


  • 30 to 50% less expensive than a new battery with the same characteristics.
