The double life of my battery
Published on
To limit the rise in temperature, the automobile industry must reduce its greenhouse gas emissions. How can this be done? By encouraging the switch to electric vehicles while optimising and extending the life of batteries. With MOBILIZE, the objective is to create sustainable ecosystems that combine electric mobility, intelligent recharging and the reuse of batteries to store renewable energy. To achieve this, MOBILIZE is combining its expertise with that of other players such as the start-up Green-Vision, based in Etampes, near Paris, which specialises in the integration of second-life batteries into other vehicles. Yann Lelong, its founder, explains how this partnership works and what it brings to life with the ex-batteries of Renault vehicles.

The battery is considered used when it leaves the vehicle at the end of its life. However, this is still more than enough for less energy-intensive applications. This is where I come in, as an integrator specialising in reconditioning.
TO EACH HIS OWN!
Aware of the potential that a battery can offer and the environmental virtue of its reconditioning, Yann Lelong, an engineer by training, with a passion for cars, mechanics and electronics, has specialised in electrification and the circular economy. Through his start-up Green-Vision, he gives a second life to the batteries of electric vehicles for customers looking for solutions compatible with their uses... and their values.
As integrators we disassemble the components of these original batteries to reassemble new packs. A bit like LEGO that we reassemble with a new weight and voltage, according to our customers' needs. This is the magic of second life.
FROM PIZZA DELIVERY SCOOTERS TO FOOD TRUCKS
These new lives are varied. For example, the batteries can be used to power two-wheelers: electrically-assisted bicycles, pizza delivery scooters or this record-breaking motorbike. Anything is possible, including performance, with second life batteries!
We still have many ideas for applications with these second-life batteries that we are developing.
