The invention relates to the field of electric vehicles, and provides an electric vehicle endurance mileage calculation method and device. The electric vehicle endurance mileage calculation method comprises the following steps: detecting parameters related to the current available real electric quantity of a battery of the electric vehicle, and / or detecting parameters related to the unit mileage power consumption of the battery of the electric vehicle; calculating the current available real electric quantity of the battery of the electric vehicle based on the parameters related to the currentavailable real electric quantity of the battery of the electric vehicle, and / or calculating the unit mileage power consumption of the battery of the electric vehicle based on the parameters related tothe unit mileage power consumption of the battery of the electric vehicle; and calculating the endurance mileage of the electric vehicle based on the calculated current available real electric quantity of the battery of the electric vehicle and / or the calculated unit mileage power consumption of the battery of the electric vehicle. According to the method and the device, the calculated endurancemileage can be more accurate.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for calculating the cruising range of an electric vehicle. Background technique [0002] The current calculation method for the cruising range of electric vehicles basically only considers the remaining power of the battery, and calculates the remaining mileage based on the remaining power and the average power usage in the previous period. However, there is a large error between the cruising range calculated by the current electric vehicle cruising range calculation method and the actual driving mileage that the electric vehicle's actual power can support. Contents of the invention [0003] In view of this, the present invention aims to propose a method for calculating the cruising range of an electric vehicle, so as to make the calculated cruising range more accurate. [0004] In order to achieve the above object, technical solution of the prese...
