World’s Largest Second-Use Battery Storage System

World’s Largest Second-Use Battery Storage System

Battery Storage System Sets The Standard.

As companies like Tesla, Nissan and Daimler gear up to provide lithium ion battery systems both the electric vehicle ( also a hybrid) and energy storage markets, the question of what to do with used batteries will need to be answered. Recovering materials and repurposing the battery itself will become a necessity in a world dependant on electric energy storage systems.

What is currently the world’s largest second-use battery storage will be starting up soon in Lünen, Westphalia. A joint venture of Daimler AG, The Mobility House AG and GETEC is going to operate the facility on the REMONDIS SE site and market the energy storage on the German primary balancing power market.

Unlike all other Mercedes-Benz Energy Storage Business systems, this solution works with used batteries. Systems from second-generation smart electric-drive vehicles are being pooled in Lünen to form a stationary storage facility with a total capacity of 13 MWh. The process has proven to improve the environmental footprint of electric vehicles and, in doing so, helps to make e-mobility cost-efficient.

High-performance battery storage systems are one of the cornerstones of successful energy transformation. As more electricity is fed in from fluctuating renewable energy sources such as wind and solar power plants they will be the key to stabilising the grids. They even out fluctuations with virtually no losses, taking over a task that is currently being performed in part by fossil-fuelled power plants. This can speed up the energy transformation and eliminate the cost of expanding the grid and building new power plants.

The third generation of the smart fortwo electric drive has been on the road since 2012 and the next generation of this electric car is ready to go. But what happens if the battery fails? Car manufacturers are prepared for this eventuality, of course, and must have suitable replacements available. This storage concept offers an innovative solution for the sustainable supply of spare batteries.

For a battery to be ready for use upon replacement, it must be regularly cycled gently charged and discharged while in storage. Otherwise, it might deep-discharge, which can damage the battery.

The highly advanced battery management system developed by Daimler subsidiary ACCUMOTIVE ensures an optimum battery state by regularly charging and discharging energy. This maintains the right temperature and charge at all times in each battery pack for compliance with strict quality and service life requirements. This procedure does not adversely affect the aging process of the systems but instead acts as a fountain of youth for the battery packs.

The spare parts store for electromotive battery systems comprises some 3,000 of the batteries that are being held in stock for the current fleet of smart electric-drive vehicles and have been pooled to form a stationary storage facility. Its storage capacity of 17,5 MWh in total makes the system one of the largest in Europe.
