The invention relates to an electric vehicle charging method based on a battery health state and time-of-use electricity price. The electric vehicle charging method comprises the following steps: step 1, obtaining a fitting relation between a user daily driving mileage and an electric vehicle charging duration; step 2, obtaining a fitting relationship between the health state of the battery and the charging times under different discharge depths; step 3, proposing a time-of-use electricity price method considering the peak-valley difference of the power grid load and the charging cost of the user, and analyzing the relationship between the charging price of the electric vehicle and the power grid load; and step 4, establishing an electric vehicle charging model taking the minimum power grid load peak-valley difference and the lowest charging cost as targets and considering the battery health state, and calculating to obtain an optimal solution so as to obtain an electric vehicle optimal charging method. According to the method, the user side demand and the battery health state maintenance demand can be considered, the peak-valley difference of the power grid load can be reduced, and the charging cost of the user is reduced.

    本发明涉及一种基于电池健康状态与分时电价的电动汽车充电方法,包括以下步骤:步骤1、得到用户日行驶里程和电动汽车充电时长的拟合关系;步骤2、得到不同放电深度下电池健康状态与充电次数的拟合关系;步骤3、提出考虑电网负荷峰谷差和用户充电费用的分时电价方法,分析电动汽车充电价格和电网负荷的关系;步骤4、建立计及电池健康状态的以电网负荷峰谷差最小和充电费用最低为目标的电动汽车充电模型,并计算得出最优解,进而获得电动汽车优化充电方法。本发明能够考虑用户侧需求和对电池健康状态维护需求的同时,还可以降低电网负荷的峰谷差,同时减少用户的充电费用。
