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.
