The invention discloses an energy management method of an electric vehicle charging station, particularly relates to the technical field of new energy charging stations, and aims to maintain normal charging through a power grid on the premise that both a charging pile and an electric vehicle support bidirectional charging, and to realize energy management through cooperation of the charging pile based on bidirectional charging and the electric vehicle. When a plurality of electric vehicles are charged at the same time and the total charging power of the charging station cannot meet the requirements of all the electric vehicles, high-power quick charging is carried out on a requesting vehicle through electric quantity feedback of a plurality of service vehicles and electric power supply of a power grid; the service vehicles can obtain corresponding service fees for price reduction after being quickly and fully charged, charging is started through a power grid, and meanwhile, comprehensive differentiation charging is performed according to the service vehicles and the request vehicles, so that the batteries of the in-station electric vehicles are fully utilized, the in-station electric vehicles serve as virtual energy storage, and the charging efficiency of the in-station electric vehicles is improved. And the problem of quick charging of the electric automobile is solved with low cost.
本发明公开了一种电动汽车充电站的能量管理方法,具体涉及新能源充电站技术领域,基于充电桩与电动汽车均支持双向充电的前提下,通过电网保持正常充电的同时,通过基于双向充电的充电桩与电动汽车配合,使其在多辆电动汽车同时充电时,且充电站的总充电功率无法满足所有电动汽车的需求时,其通过若干个服务车辆的电量反馈,配合电网的电力供给,使其给请求车辆进行大功率的快速充电,使其快速充满后服务车辆可获取相应的服务费进行减价,并通过电网开始充电,同时依据各服务车辆以及请求车辆进行综合差异化收费,以此在充分利用站内电动汽车的电池,使得站内电动汽车充当虚拟储能,低成本解决了电动汽车快速充电问题。
