The invention discloses a new energy vehicle endurance mileage estimation method and device, and the method comprises the steps: obtaining the voltage and current of a power battery of a vehicle collected by a vehicle battery management system, obtaining an endurance mileage query request of a user, and determining a corresponding integral mode for calculating the discharge amount according to the endurance mileage query request of the user; integrating the voltage and the current according to an integration mode to obtain the discharge capacity of the battery, and determining the power consumption of the vehicle according to the discharge capacity of the battery and the mileage of the vehicle within the time when the discharge capacity of the battery is consumed; and acquiring a power consumption group composed of a plurality of power consumptions, calculating the average power consumption of the power consumption group, and determining the endurance mileage of the vehicle according to the current electric quantity of the vehicle, the reserved electric quantity and the average power consumption. According to the invention, the problem that accuracy and simplicity cannot be taken into account during vehicle endurance mileage estimation in the prior art is solved.

    本发明公开了一种新能源车辆续航里程预估方法及装置,该方法包括:获取车辆电池管理系统采集到的车辆的动力电池的电压和电流,并获取用户的续航里程查询请求,根据用户的续航里程查询请求确定对应的放电量计算的积分方式;根据积分方式对电压和电流进行积分得到电池放电量,并根据电池放电量以及在消耗电池放电量的时间内车辆的行驶里程确定车辆的电耗;获取多个电耗组成的电耗组,并计算电耗组的平均电耗,根据车辆的当前电量、预留电量以及平均电耗确定车辆的续航里程。本发明解决了现有技术中在进行车辆续航里程预估时无法兼顾准确性和简便性的问题。
