each battery is marked with a number, the number is unique, and the single batteries contained in the batteries are marked according to a number-arrangement number, such as a number-x, wherein x is a positive integer;
after the vehicle is started for the first time after the battery is replaced, the replaced battery is bound with the frame number of the corresponding vehicle, the discharging behavior of the running of the vehicle is judged, the judging conditions comprise the using state of the vehicle, the using state of the battery and the real-time speed of the vehicle, and the battery is judged to be in the discharging behavior of the running only under the conditions that the vehicle is in the using state, the battery is in the using state and the real-time speed of the vehicle is greater than zero;
when the battery is judged to be in a running discharging behavior, recording a first piece of data (comprising time, an Soc value, a battery temperature and current running mileage) of the battery from starting to corresponding data when the vehicle reduces the Soc value by one percent, and calculating the mileage of the vehicle when the Soc value changes by one percent;
