The embodiment of the invention provides a method and device for calculating the remaining mileage of an electric vehicle and the electric vehicle. The method is applied to a vehicle control unit of the electric vehicle. After the vehicle driving information and the residual battery energy of the current preset sampling mileage are obtained, the driving energy consumption per kilometer of a motor, the real-time energy consumption per kilometer of the motor and the energy consumption per kilometer of a high-voltage accessory in the next preset sampling mileage can be calculated based on the vehicle driving information; calculating the remaining mileage according to the driving energy consumption per kilometer of the motor in the next preset sampling mileage, the real-time energy consumption per kilometer of the motor, the energy consumption per kilometer of the high-voltage accessory and the remaining battery energy; according to the method, the remaining mileage can be accurately calculated based on the vehicle driving information and the remaining battery energy by utilizing the vehicle control unit on the electric vehicle, the remaining mileage does not need to be calculated by depending on cloud computing and cloud service, and then the calculation cost is saved.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for calculating the remaining mileage of an electric vehicle and an electric vehicle. Background technique [0002] Electric vehicles have become the mainstream trend of the future development of new energy vehicles because of their advantages of zero emission, low noise, energy diversification, and high energy efficiency. [0003] In the process of driving an electric vehicle, the real-time and accurate prediction of the driving range can prevent the battery system from abnormally interrupting the power system due to the error of remaining mileage during use, effectively relieve the mileage anxiety of drivers and passengers, and help the driver to adjust the driving plan reasonably, and then Improve users' confidence in the use of pure electric vehicles. [0004] At present, the driving behavior model based on the cloud is often used to predict the...
