容积卡尔曼滤波测量方程基于统计数据，利用蒙特卡罗方法抽取私家电动汽车一次出行里程数，根据电池充电特性及车辆行驶习惯获得电动汽车充电的起始荷电状态、充电功率和起始充电时间，建立了一个较为精确的预测无线充电私家电动汽车充电负荷的数学模型，(The volume Calman filter measurement equation is based on the statistical data, using Monte Carlo method to extract the first trip mileage of private electric vehicles. Based on the battery charging characteristics and vehicle driving habits, the initial charge state, charging power and starting charge time of the electric vehicle charging are obtained. A more accurate prediction radio is established. A mathematical model of charging load for private electric vehicles.)
