The Department of Energy and Climate Change funded EVEREST energy storage project is now giving a 2nd life to used electric vehicle batteries, by providing grid support for electric vehicle charging at the Lotus Cars manufacturing site in Norfolk.

The newly commissioned energy storage system charges and discharges to manage and control the load that an electric vehicle rapid charger places on the local electricity network.

The system promises a potentially cheaper and faster alternative to increasing grid connection capacity as demand for EV rapid charging continues to grow.

When commercialised, the system will reuse the increasing quantities of lithium ion batteries that have become depleted by their use in electric vehicles. The reduced capacity of the batteries may make them unappealing for electric vehicle drivers but they remain suitable for many stationary electricity storage applications.

The project was contracted by DECC in 2014, to prove that the so called 2nd life batteries could be used to manage the load that clusters of electric vehicle chargers will place on the grid network. An additional benefit is that the same system could discharge electricity back to the grid network on demand.

The EVEREST project is led by Evalu8 Transport Innovations with technical leadership and project management provided by Future Transport Systems. Other partners include battery specialists Goodwolfe Energy, electric vehicle charging infrastructure specialists APT Technologies and Circontrol.

“With sales of electric vehicles growing dramatically we expect the demand for rapid chargers to grow too, as drivers seek to extend their range.  Clusters of chargers are likely to develop along major routes. The EVEREST storage technology is ideally suited to managing the increasing loads on the grid network, thus avoiding costly reinforcement,” commented EValu8’s Managing Director, Keith Bevis.

Ian McDonald, Technical Director of Future Transport Systems said, “This is a double win, the use of 2nd life batteries for this application should not only assist in the development of charging infrastructure for EV drivers but also contribute to the sustainability credentials of the EVs themselves.”

The EVEREST consortium includes:

Evalu8 Transport Innovations – Recharging network provider and Consortium lead.

Future Transport Systems – Technical lead, back office integration and project management.

Goodwolfe Energy – Cell integrator and battery specialist, battery build and test.

APT Technologies – EV charging equipment provider

Circontrol – Power electronics supplier, power conditioning and monitoring equipment
