Renault and industry leader in the provision of energy storage solutions Connected Energy will join forces to develop E-STOR, a flexible and environmentally friendly energy management system.


Connected Energy E-STOR is an energy storage system that can reduce costs and enable more flexible and efficient use of energy – including high capacity fast charging. It's environmentally sustainable as it stores energy from on-site renewable generation resources such as solar panels and wind turbines. The energy is then released when 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. The first E-STOR product is nominally rated at 50kW/50kWhr which could typically be used to support one rapid charger or a cluster of fast chargers but the system is fully scalable and higher capacity units will follow.

The second-life application system could also be used to charge the fast-charging stations in places, where it is otherwise impossible to connect them to the grid. Instead of having rapid electric vehicle charging station connected directly to a weaker 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.

In this partnership, Renault will provide Renault EV batteries at the end of their useful in-vehicle life, meaning EVs can't use them anymore, but they still have considerable remaining capacity – certainly enough to make good use of it. Renault should not suffer from a shortage of used batteries since they sold 97,687 new EVs in Europe in 2015, which is 48% more than in 2014.
