And S102, before the new energy automobile is charged for the first time, the charging and discharging parameters cannot be obtained, for example, the battery of the automobile needs to be replaced at a high speed, at this time, in order to avoid the power battery pack from being replaced by mistake, the health degree of the battery needs to be preferentially measured, and the inconsistency of the power battery pack is determined based on the temporary working characteristic parameters. The inconsistency of the power battery pack is mainly reflected in the difference of the electric quantity or the health state of each storage battery in the battery pack, a module for detecting the consistency of the battery pack is arranged in the market at present, and the consistency characteristic of the power battery pack can be directly calculated according to the working characteristic parameters of the power battery pack. When the health degree of a certain storage battery of the battery pack is poor, the endurance influence on the battery pack is large, and when the consistency is high and the overall internal resistance and other parameters are low, the health value is high, so that the battery pack can be used for endurance for a longer time for the same user.

S103, determining a health value of the power battery pack based on the inconsistency of the power battery pack; the health value of the battery pack is mainly embodied as the service life of the power battery pack, the longer the health value is, the longer the service life of the power battery pack is, and the lower the health value is, the shorter the service life of the power battery pack is.

S104, acquiring driving habit parameters stored in a preset driving time range of the new energy automobile; wherein the start-stop driving habit parameter is configured to reflect the driving habit of acceleration or deceleration of the user. The driving habit parameters can be the number of times of starting and stopping of the user, the acceleration of braking of the user, the acceleration of starting of the user and the average driving speed of the user. The higher the driving habit parameter of the user is, the lower the acceleration of the user is and the closer the average driving speed is to the recommended driving speed of the new energy automobile. The more the user starts and stops, the higher the oil consumption. The preset travel time range may be a driving habit parameter within the last 10 hours.

And S105, determining the cruising range of the new energy automobile based on the health value and the driving habit parameter. The health value and the driving habit parameter are related parameters of the cruising kilometer of the new energy automobile, wherein the higher the health value is, the more cruising kilometers are when the driving habit parameter is fixed; when the health value parameter is fixed, the driving habit parameter is higher (the driving habit is better), and the cruising range is increased.

Less than the charge threshold indicates that the power battery pack may be temporarily charged, while protection of the battery may not be possible when its total charge is high.

S202, acquiring temporary working characteristic parameters of the power battery pack in the temporary charging process and the temporary discharging process. The acquisition time of the temporary working characteristic parameters is determined by the charging or discharging change of the power battery pack, the total electric quantity of the power battery pack and the change condition of the total electric quantity in the temporary charging process and the temporary discharging process of the power battery pack.

And receiving the selection operation of the power battery pack detected by the user aiming at the selection control, and detecting the electric quantity of the standby power supply. When the user selects no, the detection and the subsequent operation of the standby power supply are not needed, and the detection is not needed; and when the user selects yes, detecting the electric quantity of the standby power supply of the new energy automobile.

And when the electric quantity of the standby power supply is larger than a preset power supply electric quantity threshold value, calling the standby power supply to temporarily charge the power battery pack and simulating the temporary discharge of the power battery pack by adopting an automobile running model. The preset power supply electric quantity threshold value can be 20% of the electric quantity of the standby power supply, and when the electric quantity of the standby power supply is larger than the preset power supply electric quantity threshold value, the standby power supply can provide standby electric quantity, so that the normal use of a subsequent new energy automobile is not influenced.

Preferably, in the present invention, in addition to the above-mentioned operation modes of S201 and S202, the obtaining of the temporary operation characteristic parameter of the power battery pack further includes a state that power supply is performed, and specifically, the operation flow includes as follows:
