Research on the Planning Method for EV Charger Allocation in Highway Network

In response to the charging challenges faced by electric vehicles (EVs) operating on highway networks, a guidance framework tailored for charging systems within these networks is proposed. By real-time analysis of data from EVs and charging stations, this framework provides EV users with rational trip planning and charging reservation services. Additionally, a planning model addressing the capacity determination of charging stations in highway networks has been introduced. This model, aiming to minimize investment costs, takes into account constraints such as user waiting times and equitably allocates the number of chargers within the stations. This not only improves charger utilization but also reduces both investment and operational costs. Lastly, the proposed method was simulated and validated on a highway network consisting of 20 charging stations. The simulation results demonstrate that this capacity planning method not only reduces investment and operating costs for charging stations but also enhances the convenience of EV users’ charging experience.
