The invention provides a method and device for determining the remaining mileage of an electric vehicle and the electric vehicle. The method for determining the remaining mileage of the electric vehicle comprises the following steps: determining the current average power consumption of the electric vehicle in unit time; acquiring current data of driving parameters of the electric vehicle; determining a power consumption standard interval of the electric vehicle according to the current data of the driving parameters; and if the current average power consumption is in the power consumption standard interval, determining the remaining mileage of the electric vehicle according to the current average power consumption. The power consumption standard interval of the electric vehicle is determined according to the current data of the driving parameters of the electric vehicle, the power consumption standard interval dynamically changes along with the driving state of the electric vehicle, and the power consumption standard interval is more suitable for the actual situation of the electric vehicle; when the current average power consumption of the electric vehicle is in the power consumption standard interval, the remaining mileage is determined according to the current average power consumption, whether the current average power consumption is abnormal or not can be judged according to the power consumption standard interval, and the remaining mileage can be determined more accurately.

    本申请提供一种电动汽车的剩余里程的确定方法、装置以及电动汽车。电动汽车的剩余里程的确定方法包括:确定电动汽车在单位时间内的当前平均电耗;获取电动汽车的行驶参数的当前数据;根据行驶参数的当前数据,确定电动汽车的电耗标准区间;若当前平均电耗处于电耗标准区间,根据当前平均电耗,确定电动汽车的剩余里程。本申请通过根据电动汽车的行驶参数的当前数据,确定电动汽车的电耗标准区间,电耗标准区间随着电动汽车的行驶状态动态变化,电耗标准区间更适应电动汽车的实际情况;当电动汽车的当前平均电耗处于电耗标准区间,则根据当前平均电耗确定剩余里程,通过电耗标准区间可以判断当前平均电耗是否发生异常,可以更准确地确定剩余里程。
