Renault and Connected Energy

For more than 4 years, we have worked with Groupe Renault to repurpose batteries that, although no longer fit to power a car, still perform extremely well for stationary energy storage applications.”

Amaury Gailliez: Our commercial and logistics partnership with Connected Energy aims to make the most of our battery’s lifespan.
A battery’s first life will last 10 to 15 years, after which point it still operates at 75% capacity or more. The second life can last another 10 years, which not only minimises each battery’s environmental footprint but also facilitates access to storage on a large scale.

What are the main benefits of using electric vehicle batteries for energy storage?

AG: Our batteries are designed for highly demanding usage. Therefore, they are designed to be durable, and reliable. When our batteries no longer operate at full capacity, they still deliver high performance in stationary use. It’s hard to think of a better use for them, given how essential energy storage will become to ensure the power grid is responsive and resilient.

ML: More and more electric vehicles on the road means more and more storage units for the future, which can be reused instead of buying and/or manufacturing new batteries. Meanwhile, the battery’s exacting design standards guarantee that we’re offering very safe and reliable products.
Linking these batteries together into integrated units, we can then use them to store renewable energy, balance the grid during peak load times, and so on.

This suddenly makes energy storage much cheaper, more readily available, and more accessible to all. Developing energy storage also means developing affordable, low carbon electricity which is good news for all sectors, including electric mobility!

It truly is a virtuous circle.
