At present, in the field of commercial vehicles and passenger vehicles, the size of the power battery is generally selected according to the cruising range conditions stipulated in the national standard or international standard, but it is not applicable to special vehicles, off-highway vehicles, heavy vehicles and other vehicles. The national standard The specified UDLC and other working conditions are not applicable to the selection of new energy power batteries for the above-mentioned vehicles, which may easily lead to excessive selection of battery capacity, resulting in excessive volume and weight of the power battery, and the vehicle is not easy to arrange and the weight is too large; or The selection of battery capacity is too small, resulting in short cruising range, frequent charging of the vehicle, and low operating efficiency

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.
Description
technical field [0001] The present application relates to the technical field of pure electric vehicles, in particular to a method for determining battery capacity of pure electric vehicles; it also relates to a device, equipment and computer-readable storage medium for determining battery capacity of pure electric vehicles. Background technique [0002] Pure electric vehicles usually use power batteries as the power source. The cruising range of the vehicle is a key indicator of pure electric vehicles. The battery capacity of the power battery of pure electric vehicles directly determines the cruising range. At present, in the field of commercial vehicles and passenger vehicles, the size of the power battery is generally selected according to the cruising range conditions stipulated in the national standard or international standard, but it is not applicable to special vehicles, off-highway vehicles, heavy vehicles and other vehicles. The national standard The specified UDL...
