Willim is undertaking a platform offering 2 innovative services in a CSR logic. Firstly, a fleet management service that allows users to be allocated a vehicle adapted to their mobility needs, while taking into account the overall carbon impact, which must be minimised. Secondly, a service allowing the battery of an electric vehicle to be used when it is stationary, by offering a link between fleet managers and aggregators. This project is in collaboration with the École des Mines and BPI France.
