Second-life batteries used in electric van

Carwatt presents a unique automotive application for second-life batteries from electric vehicles

On the sidelines of the COP21 summit, in the Solutions Gallery running from 2 to 9 December 2015 in Le Bourget near Paris, Carwatt and its partners —Renault, Paris City Council, BPI France, the Alès École des Mines Engineering School, and the Bobigny Business Campus — are showing a very special electric Renault Trafic. This prototype vehicle, the only one of kind in the world, is powered by second-life lithium-ion batteries recycled from Renault electric cars.

Circular economy at work with electric vehicles

When, over time, the batteries of a Renault electric vehicle fall the performance threshold specified for their initial automotive power duty (around 75% of initial capacity), they can still provide valuable service in “second-life” applications before end-of-life disposal at a recycling centre. Experiments are already under way on power storage applications, for example.

EV Spotting

I see more electric cars on the road every day now, they are no longer the novelty they used to be. In my area I see many Nissan Leafs and a few ZOEs. And, of course, it seems like the Mitsubish Outlander PHEV is everywhere!

I saw my first Tesla Model S in my hometown of Northampton a few months back – that seems like a milestone of sorts.

A week later I was travelling down to London and called in to the London Gateway services for a charge. By the time I had finished and was packing up to leave I had been joined by an Outlander and a BMW i3, all 3 cars lined up in a row at the chargepoints. Hopefully such a tableau will be commonplace in the future.

Of course, it did highlight that only the ZOE has its charging socket at the right end!
