Thesis: Vehicle-to-vehicle fast charging from a shared vehicle fleet

Yacine SEHIMI, Researcher PhD Candidate, will submit his thesis on 7 July 2022 at 2 PM on “the design of a vehicle-to-vehicle fast charging network and infrastructure based on a shared vehicle fleet“. Sharing would limit the impact of recharging on the grid at times of high electricity demand. The thesis also presents a tool for simulating power control during the transfer between vehicles.

This thesis will take place at T128 – T130, 13 Rue de Toul 59000 Lille.

Resume

V2V fast charging enables to recharge an electric vehicle by partially discharging one or several other electric vehicles having an excess of energy.  The use of a fleet of carsharing electric vehicles as energy providers allows the carsharing operator to make additional profits when they are not rented.

Moreover, the recharge of the fleet can be achieved at lower power than the V2V power transfer. Therefore the grid connection required to provide fast charging is reduced, which can mitigate the necessary grid upgrades. Besides, the lower power demand of the station could reduce the impact of electric vehicle charging at hours of peak power demand on the grid.

This thesis is a collaboration between Institut Vedecom and L2EP Laboratory. In a first part, the  goal is to build a simulation model of the coupled carsharing/V2V system, in order to assess  the benefits for the actors of the grid, namely the Distribution System Operator and the Transmission System Operator.  In a second part, the design of a power converters architecture to control power flow between the vehicles involved and the grid is proposed and the control strategy is implemented through simulations. Finally an experimental setup of the multi-source DC/DC converter is achieved in order to validate the proposed control strategy.
