Second life for traction batteries in Amsterdam football arena

June 29, 2018 // By Christoph Hammerschmidt
Power management system vendor Eaton, carmaker Nissan and electric mobility services provider The Mobility House have implemented an energy storage system consisting of new and used batteries of electric cars in the Johann Cruijff Arena in Amsterdam.

The 3-megawatt energy storage system in the Johan Cruijff Arena, the stadium of football club Ajax Amsterdam, is intended to ensure a more reliable energy supply in the stadium. The system consists of bidirectional inverters from Eaton and traction batteries. A large proportion of the batteries had previously been used in electric vehicles. The batteries have already reached the end of their life cycle and are therefore much more sustainable than new battery systems, the companies argue. Battery cells with a total capacity of 2.8 MWh are installed. This corresponds to the battery capacity of 148 Nissan Leafs.

Thanks to the energy storage system, the stadium can use the solar energy it generates more sustainably and intelligently. In addition, the football club can market its stored energy. In the event of a power failure, the battery storage will provide the arena with a considerable amount of energy. The stadium thus increases its supply safety and also contributes to stabilising the electricity grid in the Netherlands.
