An Adaptive Charging Control Strategy for Electric Vehicles Based on Wi-Fi Technology

Abstract:

The uncertainty of driving area, the power load control of charging facility and charging rates make electric vehicles(EVs) facing different charging facilities, so it is necessary to control charging in the charging process. An adaptive electric vehicle charging control strategy was proposed in this paper. The strategy uses wifi for communication, communicating with charging pile through wifi, charging facilities and electric vehicles can exchange parameters to achieve adaptive control of the charging process. And experiment was conducted for verification.
