Renault has done a deal with energy storage providers Connected Energy Ltd to provide used batteries from electric vehicles (EVs) for a second-life application.
Connected Energy’s E-STOR system will use these batteries for internal electricity storage in a system that can reduce costs and allow a more efficient use of energy – including fast charging EVs.
At the end of their useful EV life, the car batteries still have a large amount of capacity remaining, and can be used in different applications before they are finally recycled. The E-STOR systems have been designed to store energy generated by on-site renewable sources such as solar panels and wind turbines. This can then be used as it is needed at a later time, boosting system capacity at peak periods or allowing off-grid vehicle charging solutions.
Connected Energy’s first system is rated at 50kW/50kWh so could support a rapid charger or bank of fast chargers. However, E-STOR has been designed to be scalable so higher capacity units will follow.
The re-use of EV batteries allows fast and rapid EV chargers to be placed where traditionally only slow chargers would be able to be supported by the national grid. It also provides environmental benefits with the batteries in use for a longer amount of time before they need recycling.
Matthew Lumsden, Managing Director of Connected Energy, said: “E-STOR will enable the more cost-effective roll-out of electric vehicles in commercial and industrial settings, thus increasing the overall sustainability of this clean form of transport. With Renault we have secured the supply of second life batteries for future E-STOR installations.”
Eric Feunteun, Electric Vehicle Program Director at Renault, commented: “The second life application of Renault electric vehicle batteries supports Renault’s commitment to the energy transition in the automotive industry. Through E-STOR, EV owners can charge their car at reduced costs with electricity that is less carbon-dependent. It makes driving an EV a smart and even more sustainable transportation solution. With this energy management technology, EVs and their batteries become an asset for the grid rather than create overload.”
