British energy storage system could revolutionise the installation of electric car rapid chargers

A new energy storage system, utilising second-life electric car batteries from Renault could revolutionise time and costs needed to install electric car rapid chargers.

Connected Energy, based in Newcastle upon Tyne and Renault have installed two rapid charger stations on highways in Belguim and Germany based on a new innovative energy storage system. The new E-STOR technology reuses batteries from Renault electric vehicles. With the E-STOR system, the batteries are recharged at low power, and the stored energy is then released at high power.  This approach makes it now possible to offer charging in locations where constructing a high power connection to the grid would be very costly.

Slowly stored energy is used to rapidly recharge cars

Economical and simple to install, E-STOR will contribute to the development of a network of rapid charging stations in Europe.

Matthew Lumsden, Managing Director of Connected Energy commented:

“We are developing a range of E-STOR systems, some, like the two installed in Belgium and Germany are designed specifically to enable lower cost more sustainable electric vehicle charging so it’s very great to see these in action.  We are now talking to several parties about projects in the UK and Europe and look forward to wide scale roll out in coming months.”

Electric vehicle batteries generally have a service life of eight to ten years. However, they still have substantial capacity for further use in stationary applications, thus extending their life before recycling. It is particularly to optimise this complete life cycle that Renault has set up the rental of the battery with its customers of electric vehicles.

Second-life batteries from Renault cars store the energy

The E-STOR systems also offer a solution to load management for use on industrial and commercial sites. Systems can be controlled to provide a reliable and proven complimentary power source at peak tariff times.  Working with a company’s onsite solar PV, or micro wind turbines, storing and releasing energy directly into site systems thereby avoiding the financial shortfalls of exporting to the Grid. E-STOR can also provide new revenue streams by providing balancing services to the grid operator.
