Efficient Electric Vehicles Assignment For Platoon-Based Charging

To fulfil the increasing charging requests of Electric Vehicles (EVs), various means have been proposed such as improving charging efficiency at charging stations, optimal locating of charging stations, enabling V2V trading and so on. Most existing work requires vehicles to be stationary while being charged. Mobile wireless charging is a promising trend to fix this problem since vehicles can perform moving and charging simultaneously. In this paper, a new concept called platoon-based charging is presented, which combines the energy-aware driving and mobile charging. In the design, an EV may have to detour to follow the platoon. To minimize the additional energy cost and delay brought by that, we studied the optimal assignment problem between EVs and charging platoons and converted it to a dynamic weight bipartite matching. The experiment results show that our algorithm outperforms the exiting ones.
