FIG. 6 is a schematic flowchart of still another battery management method according to an embodiment of the present disclosure. As shown in FIG. 6 , the method provided in this embodiment includes the following steps:

Step 401: The battery device acquires attribute information of the battery.

Step 402: The battery device sends the attribute information of the battery to the server.

Step 403: The server receives attribute information of the battery sent by the battery device.

Step 404: The battery device acquires the number of times of charging and discharging of the battery and the battery life.

Step 406: The battery device calculates an average charge and discharge ratio of the battery according to the charging history and the discharge history.

It is worth noting that the average charge-discharge ratio of the battery can reflect the performance of the battery. Assume that the battery needs Q1 power from voltage V1 to voltage V2. The voltage is reduced from V2 to V1 to get Q2 power. Since the battery itself has a certain power loss, Q2 is less than Q1, and the amount of Q2 is less than Q1 is affected by the performance of the battery. The average charge-discharge ratio of the battery can be calculated to reflect the performance of the battery.

The charge-discharge ratio is used to plot the charge-discharge ratio curve of the battery in the range of (V _i , V _i+1 ), which is used as a criterion for judging the merits of the battery.

Step 406b1, calculating the average charge/discharge ratio E _{(k, n) of the} battery based on E _k , E _k+1 ... E _n .

or,

Step 406a2, calculating the charge-discharge ratio E _i of the (V _i , V _i+1 ) interval of the battery according to Q _{c i} and Q _d _i .

It is worth noting that i=k, k+1...n-1.

Step 406b2, calculating the average charge-discharge ratio E _{(k, n) of the} battery according to E _k , E _k+1 ... E _n and the preset proportional weight values w _k , w _k+1 ... w _n .

It should be noted that the preset proportional weight values w _k , w _k+1 ... w _n may be preset, and w _k +w _k+1 +...+w _n =1. Since the reference value of the charge-discharge ratio of the voltage in the lower range interval and the upper range interval is slightly lower, in general, the weight values w _k and w _n are compared with other weight values w _k+1 ... w _n-1 small.
