The invention discloses a battery capacity determination method of a pure electric vehicle and a related device. The method comprises steps of determining a road condition type of the pure electric vehicle in single cycle operation according to an operation scene of the pure electric vehicle; respectively calculating the braking energy consumed or recycled by the pure electric vehicle under each road condition type, and according to the braking energy consumed or recycled by the pure electric vehicle under each road condition type, calculating to obtain the battery capacity consumed by the pure electric vehicle in a single cycle operation; according to the cycle operation frequency of the pure electric vehicle in the unit time and the battery capacity needing to be consumed by the pure electric vehicle in the single cycle operation, the battery capacity needing to be consumed by the pure electric vehicle in the unit time being obtained through calculation; and determining that the capacitance capacity of the pure electric vehicle is at least the battery capacity consumed by the pure electric vehicle in unit time. According to the method, a reliable basis can be provided for battery capacity selection, and the battery capacity selection is prevented from being too large or too small.

    本申请公开了一种纯电动车辆的电池容量确定方法及相关装置,包括根据纯电动车辆的作业场景,确定纯电动车辆在单次循环作业中的路况类型;分别计算纯电动车辆在各路况类型下消耗或回收的制动能量,并根据纯电动车辆在各路况类型下消耗或回收的制动能量,计算得到纯电动车辆在单次循环作业中所需消耗的电池容量;根据单位时间内纯电动车辆的循环作业次数以及纯电动车辆在单次循环作业中所需消耗的电池容量,计算得到纯电动车辆在单位时间内所需消耗的电池容量;确定纯电动车辆的电容容量至少为纯电动车辆在单位时间内所需消耗的电池容量。该方法能够为电池容量选型提供可靠依据,避免电池容量选型过大或过小。
