The invention belongs to the field of electric vehicle charging strategies, and particularly relates to an electric vehicle charging strategy method based on time price weights. According to the charging time and the price priority set by the user, the charging mode when the charging power of the area cannot meet the requirement of full-power charging of all vehicles in the area is determined, information such as the real-time charging power and the charging duration of the vehicles is obtained during charging, and the information entropy is calculated; and calculating an actual charging power distribution weight of the vehicle in real time according to the negotiated charging mode, calculating real-time charging distribution power of the vehicle according to the total electrical load condition, the power limitation condition and the like of the current area and weight priorities, and iteratively adjusting the real-time charging power according to the actual charging power and the distribution power. The method can realize ordered charging of the electric vehicle when the upper limit of the power limit value exists in the region, improves the power utilization efficiency in the region, and relieves the pressure of the regional power grid.
本发明属于电动汽车充电策略领域,具体涉及一种基于时间价格权重的电动汽车充电策略方法。本发明通过用户设置的充电时间和价格优先度确定当区域充电功率无法满足区域所有车辆满功率充电时的充电方式,充电时获取车辆实时充电功率、充电时长等信息,计算信息熵,根据协商的充电方式实时计算车辆实际充电功率分配权值,并根据当前区域总用电负荷情况、功率限定情况等,按权值优先级计算出汽车实时充电分配功率并根据实际充电功率和分配功率迭代调整实时充电功率。该方法可实现当区域存在功率限值上限时的电动汽车的有序充电,提升区域内用电效率,缓解区域电网压力。
