An Electric Vehicle Routing Optimization Model With Hybrid Plug-In And Wireless Charging Systems

In order to address the inconvenience of having to stop to charge the battery of an electric vehicle, wireless on-road charging technology, also known as charge-while-driving, has garnered much attention in recent studies. However, wireless charging devices may have a higher charge cost than traditional plug-in charging devices. Therefore, a multi-objective route optimization model based on model predictive control is established in this paper to determine an optimal route for drivers to coordinate wireless and plugin charging strategies. To reduce the complexity of the proposed model due to its bilinear terms, the Big-M approach is employed to exactly linearize the bilinear terms by introducing dummy variables and additional constraints, which leads to a mixed integer linear programming model that can be solved efficiently. Finally, two systems are tested, including a real-world road map in Xi'an city to demonstrate the effectiveness of the proposed model.
