Abstract

Provided is an electric vehicle driving mileage calculation method, comprising the following steps: calculate the energy consumption of a power battery of the electric vehicle per unit driving mileage; obtain the open-circuit voltage (OCv)-battery capacity (Q) reference curve of the power battery; obtain the OCv of the power battery; obtain the currently remaining available energy of the power battery according to the OCv and the OCv-Q reference curve of the power battery; calculate the driving mileage of the electric vehicle according to the energy consumption of the power battery per unit driving mileage and the currently remaining available energy of the power battery, whereby the driving mileage of the electric vehicle which is calculated is more accurate. Also disclosed is an electric-vehicle driving mileage calculation device and an electric vehicle.
