Giving a second life to EV batteries, E-STOR is a scalable, modular setup that adds flexibility to the electricity grid and offers EV charging solutions.

Ninety-five percent of energy for transport comes from fossil fuels, but that is changing as the market for electric vehicles (EVs) expands. With a growing number of used EV batteries becoming available for reuse, Connected Energy is building E-STOR, a solution that uses second-life Renault EV batteries for grid-scale electricity storage. Such storage is playing an greater role in the wider grid, with governments and companies pushing its development thanks to its ability to save costs and support renewables. The units can also be connected to EV fast-charging stations to help scale that technology.

This solution was featured in Reuse to Repower market of the 2018 Global Opportunity Report, and was selected based on the criteria of that report. 

How the Global Goals are addressed

Affordable and Clean Energy

As electricity grids rely more on variable renewables, grid-scale storage is becoming a key factor for reducing dependency on fossil fuels at peak times.

Sustainable Cities and Communities

E-STOR’s use of rapid-charging stations where grid connections are limited can help to scale sustainable transport systems.

Responsible Consumption and Production

Finding a second use for batteries before eventual recycling is a truly circular way of using valuable resources.
