Document Type and Number:
WIPO Patent Application WO/2019/113828
Kind Code:
A1
Abstract:
A method for acquiring the remaining mileage of a pure electric vehicle. The method comprises: acquiring the remaining electric energy of a battery of a pure electric vehicle; collecting the maximum temperature, a discharge current, a health state parameter and an electricity consumption amount of the battery of the pure electric vehicle within a set unit of time, and a current voltage of the battery; according to the maximum temperature, the discharge current, the health state parameter and the electricity consumption amount of the battery within the set unit of time, the current voltage of the battery, and the speed of the pure electric vehicle within the set unit of time, determining an electric energy consumption value per unit of mileage of the pure electric vehicle within the set unit of time; and according to a ratio of the remaining electric energy of the battery to the electric energy consumption value per unit of mileage within the set unit of time, determining the remaining travelling distance of the pure electric vehicle. The method can improve the accuracy of acquiring the remaining mileage of a pure electric vehicle. Further disclosed are an electronic device (20), an apparatus (30) having a storage function, and an electric vehicle.
