BMW and Bosch’s Second-Life 2.8 MWh Energy Storage Solution in Hamburg
A massive 2.8 MWh / 2 MW energy storage system made from second life electric car batteries has entered service in Hamburg, Germany.
Together, Vattenfall, BMW and Bosch have used 2,600 battery modules from over 100 cars to complete the project.
The Battery 2nd Life project will map out the long term abilities of re-used batteries, as well as provide a buffer for Hamburg’s HafenCity district.
“The Battery 2nd Life development project organized by Vattenfall, BMW and Bosch kicked off in 2013 for a planned term of five years.
The project partners hope to learn more about the ageing characteristics and storage capacity of used lithium-ion battery modules. Along with the electricity storage facility near the Steinwerder Cruise Centre in Hamburg, the project encompasses two other measures: Used batteries have been providing interim storage and power buffering for fast-charge stations in Hamburg’s HafenCity district since September 2014. In another application, energy consumption from the photovoltaic facility of Vattenfall’s HafenCity district heating station is being maximized by interim storage of energy in batteries during sunny periods with low electricity demand.”
Cordelia Thielitz, General Manager of Bosch Energy Storage Solutions said:
“Bosch develops turnkey storage solutions for energy suppliers and industrial enterprises. Electricity storage systems are a key success factor for the new energy landscape.
Thanks to smart electronic controllers, these storage systems can absorb excess electricity and release it again very quickly when needed. That way they help to stabilize the electricity grid. We expect to gain valuable knowledge from the Battery 2nd Life development project, and we regard it is as an important step on the way to a more efficient and more decentralized energy system,”.
Dr Bernhard Blättel, Vice President Mobility Services and Energy Services, BMW Group:
“The BMW Group is fully committed to electromobility with our BMW i model. Initiator projects for the charging infrastructure and energy management play a key role in this. The battery storage facility officially opened today represents an important milestone in the further optimisation of battery management. In future, with BMW Storage we will be able to offer efficient battery storage solutions tailored to customer needs.
In the context of the new energy landscape, the BMW Group regards energy storage as the core component of energy management. That applies to storage in vehicles as well as stationary storage systems. In future, battery storage systems will also make a significant contribution to increasing the sustainability of electromobility. We can look back on a successful collaboration, and we have gained valuable insights from this cooperative development project.”
