Connected Energy and Renault to collaborate on energy storage and EV charging technology

Renault will provide used EV batteries to Connected Energy Ltd for second-life application in its E-STOR product
E-STOR is a revolutionary energy storage system that can reduce costs and enable more flexible and efficient use of energy – including high capacity fast charging

Renault and Connected Energy are partnering to develop sustainable and efficient ways of using electric vehicle batteries at the end of their useable in-vehicle life in order to supply innovative and more affordable vehicle charging solutions.

At the end of their useful in-vehicle life, Renault EV batteries still have considerable remaining capacity, which means that they can continue to give great service in other applications before they are ultimately recycled.

Through its award-winning E-STOR technology, Connected Energy is offering a highly innovative solution to this conundrum through use of ‘second life’ EV batteries.

This can be used, for example, to store energy generated from on-site renewable generation resources such as solar panels and wind turbines, and then release it as it’s needed at a later time. The system also allows the batteries to be charged via low-cost off-peak electricity tariffs, enabling users to reduce their energy costs.

In practical terms, as well as allowing more efficient use of energy, the system can also enable installation of rapid electric vehicle charging in sites where electricity supply would traditionally only allow slower rates. Instead of charging vehicles via a high-capacity supply directly from the grid, E-STOR allows multiple batteries to be charged at a slower rate over a period of time, ready to release their energy and charge a car when an EV driver needs it.

Renault offers two concrete solutions with its electric vehicles and their batteries through E-STOR. First to the grid, by providing energy storage that prevents power grid overload and balances supply and demand. Second to the environment, because batteries not fitted for automobile use, but that still have considerable remaining capacity, can have a longer life and lower carbon footprint before they are actually recycled.

In June 2015, E-STOR was named winner of the innovation category in the prestigious British Renewable Energy Awards 2015, hosted by the Renewable Energy Association.
