Problems solved by technology
[0004] However, the above method has high requirements on the driver model and vehicle dynamics model, and the process of establishing the model is complicated. If the model is not accurate enough, the predicted driving range will have a large error, resulting in a decrease in the driving experience of the driver.

The invention discloses an electromobile driving mileage estimation method, an electromobile driving mileage estimation device and an electromobile. The electromobile driving mileage estimation method comprises the following steps: receiving current battery code information transmitted by a battery management system (BMS); comparing the current battery code information with battery code information stored in an electric erasable programmable read-only memory (EEPROM); if the current battery code information is not consistent with the battery code information, transmitting the current battery code information to a server by using a data collection terminal RMS, and receiving historical accumulated mileage and historical accumulated power consumption corresponding to the current battery code information, returned by the server, by adopting the data collection terminal RMS; obtaining the current battery initial available electric quantity transmitted by the battery management system (BMS); and calculating the initial driving mileage value according to the current battery initial available electric quantity, the historical accumulated mileage and the historical accumulated power consumption.
Description
Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method and device for estimating the driving range of an electric vehicle, and an electric vehicle. Background technique [0002] An electric vehicle refers to a vehicle that is powered by an on-board power supply, drives wheels with motors, and meets the requirements of road traffic and safety regulations. Compared with traditional cars, it is more energy-saving and environmentally friendly. However, due to the small battery capacity and the limited mileage per full charge, users with "range anxiety" will worry about whether the battery power can guarantee the vehicle's destination. Therefore, an accurate prediction of electric vehicles is needed. The method of driving mileage. [0003] At present, the existing methods mainly use the driver model and the vehicle dynamics model to predict the future energy consumption of the vehicle, and use the electrothermal coupling mod...
