step 101, receiving a query request carrying attribute information of a battery to be monitored, which is sent by a first terminal.
Specifically, the step 101 of receiving the query request carrying the attribute information of the battery to be monitored sent by the first terminal may be implemented by a server.
And 102, inquiring the ID number of the candidate battery and the battery replenishment station information of the candidate battery in a dynamic inquiry table according to the attribute information of the battery to be monitored.
It should be noted that the dynamic lookup table is pre-established and stored in the server. The candidate battery refers to a battery having the same attribute as the battery to be monitored, i.e. a battery that can replace the battery to be monitored,
specifically, step 102 of querying the ID number of the candidate battery and the battery replenishment station information to which the candidate battery belongs in the dynamic lookup table according to the attribute information of the battery to be monitored may be implemented by a server. The number of the candidate batteries may be one or more, specifically, the number of the candidate batteries is determined by querying the dynamic lookup table for the number of the batteries with the same attributes as the batteries to be monitored, and the dynamic lookup table for the number of the batteries with the same attributes as the batteries to be monitored.
Step 103, the ID number of the candidate battery and the battery replenishment station information of the candidate battery are sent to the first terminal.
The ID number of the battery candidate and the battery replenishment station information to which the battery candidate belongs are used for the user to determine the target battery.
Specifically, step 103 may be implemented by the server sending the ID number of the candidate battery and the battery replenishment station information to which the candidate battery belongs to the first terminal. From the number of the battery candidates, the ID number of the battery candidate and the battery replenishment station information to which the battery candidate belongs are transmitted to the first terminal, and assuming that the three battery candidates are the battery candidate a, the battery candidate B, and the battery candidate C, the ID number of the battery candidate a, the battery replenishment station information to which the battery candidate a belongs, the ID number of the battery candidate B, the battery replenishment station information to which the battery candidate B belongs, and the ID number of the battery candidate C, the battery replenishment station information to which the battery candidate C belongs are transmitted to the first terminal.
According to the battery management method provided by the embodiment, a server receives a query request carrying attribute information of a battery to be monitored, which is sent by a first terminal; inquiring the ID number of the candidate battery and the battery replenishment station information of the candidate battery in a dynamic inquiry table stored in a server according to the attribute information of the battery to be monitored; transmitting the ID number of the candidate battery and battery replenishment station information to which the candidate battery belongs to a first terminal so that a user determines a target battery; therefore, the server only needs to search the ID number of the battery with the same attribute as the battery of the user automobile and the information of the battery replenishing station to which the battery of the user automobile belongs according to the attribute information of the battery of the user automobile sent by the user, and return the information to the user, so that the user can determine the battery which is finally used for replacing the battery of the user automobile from the information and go to the battery replenishing station where the finally determined battery is located to obtain the battery, and the user does not need to go to a charging pile to charge and wait for the charging process to finish, thereby greatly saving the time.
Fig. 3 is a flow chart of another battery management method according to an embodiment of the present invention, as shown in fig. 3, the method provided in this embodiment includes the following steps:

Step 202, when the electric quantity of the battery to be monitored is smaller than a preset threshold value, a query request carrying attribute information of the battery to be monitored is sent to a server.
It should be noted that, the preset threshold is a preset threshold, so that the representation of the preset threshold should be consistent with the representation of the electric quantity of the battery to be monitored in order to be able to compare with the electric quantity of the battery to be monitored, if the electric quantity of the battery to be monitored is represented by ampere hours, the preset threshold should also be represented by ampere hours, and if the electric quantity of the battery to be monitored is represented by percentage of the remaining electric quantity of the battery, the preset threshold should also be represented by percentage of the remaining electric quantity of the battery.
Specifically, when the electric quantity of the battery to be monitored is less than the preset threshold in step 202, the sending of the query request carrying the attribute information of the battery to be monitored to the server may be implemented by the first terminal.
Step 203, receiving the ID number of the candidate battery and the battery replenishment station information of the candidate battery sent by the server.
Specifically, step 203 of receiving the ID number of the candidate battery and the battery replenishment station information to which the candidate battery belongs, which are sent by the server, may be implemented by the first terminal.
Step 204, displaying the ID number of the candidate battery and the battery replenishment station information of the candidate battery.
The ID number of the battery candidate and the battery replenishment station information of the battery candidate are used for the user to determine the target battery.
Specifically, step 204 shows that the ID number of the candidate battery and the battery replenishment station information of the candidate battery may be implemented by the first terminal. If there are a plurality of candidate batteries, the ID number of the candidate battery corresponds to one battery replenishment station information, and the ID number and the battery replenishment station information of any one candidate battery should be displayed separately from the ID numbers and the battery replenishment station information of other candidate batteries so that the user cannot specify the battery replenishment station information corresponding to the ID number of a certain candidate battery.
According to the battery management method provided by the embodiment, a first terminal acquires the electric quantity of a battery to be monitored; when the electric quantity of the battery to be monitored is smaller than a preset threshold value, sending a query request carrying attribute information of the battery to be monitored to a server; receiving and displaying the ID number of the candidate battery and the battery replenishment station information of the candidate battery sent by the server; therefore, the first server only needs to display the ID number of the battery and the information of the battery supply station which are the same as the battery to be monitored when the electric quantity of the battery to be monitored is smaller than the preset threshold value through the sending and receiving processes, so that the user can determine the battery which is finally replaced by the battery to be monitored according to the displayed information and go to the battery supply station where the finally determined battery is located to obtain the battery, the user does not need to go to the charging pile to charge and wait for the charging process to finish, and the time is greatly saved.

Specifically, once the attribute information of the plurality of batteries is the same, the plurality of batteries may be used interchangeably. The battery device is provided with a chip in which attribute information of the battery is stored, and the attribute information of the battery can be obtained by reading the chip.
Step 302, the battery device sends attribute information of the battery to the server.
The attribute information of the battery is used for the user to determine the target battery.
Specifically, the sending of the attribute information of the battery to the server is completed at the beginning, and the battery device may or may not have a networking function.
Step 303, the server receives the attribute information of the battery transmitted by the battery device.

Specifically, the number of the second terminals may be one or more, and is specifically determined by the number of the battery replenishment stations, the second terminals are disposed in the battery replenishment stations, each second terminal counts the batteries in the battery replenishment station where the second terminal is located, and it is assumed that the number of the battery replenishment stations is three, namely, the battery replenishment station a, the battery replenishment station B and the battery replenishment station C, and one second terminal is respectively disposed in the battery replenishment station a, the second terminal in the battery replenishment station a counts the batteries in the battery replenishment station a, the second terminal in the battery replenishment station B counts the batteries in the battery replenishment station B, and the second terminal in the battery replenishment station C counts the batteries in the battery replenishment station C.

Specifically, assuming that the battery 1 is in the battery replenishment station a and the battery 2 is in the battery replenishment station B, transmitting the information of the battery replenishment station to which the battery belongs to the server means transmitting information like "the battery replenishment station to which the battery 1 belongs is the battery replenishment station a and the battery replenishment station to which the battery 2 belongs is the battery replenishment station B".
It should be noted that, there is no logical sequence between the steps 304 to 306 implemented by the second terminal and the steps 301 and 302 implemented by the battery device, that is, the steps 304 to 306 may be implemented by the second terminal while the steps 301 and 302 are implemented by the battery device.
Step 307, the server receives the battery replenishment station information of the battery sent by the second terminal.
Step 308, the server assigns an ID number to the battery device.
Specifically, the ID number is a unique identification of the battery devices, one battery device corresponds to one ID number, and one battery device can be determined based on the ID number.
Step 309, the server establishes a dynamic lookup table according to the attribute information of the battery, the ID number of the battery, and the battery replenishment station information to which the battery belongs.
Specifically, the dynamic lookup table is a table in which attribute information of the battery, an ID number of the battery, and battery replenishment station information to which the battery belongs are in one-to-one correspondence. Assuming that there are battery 1 and battery 2, the battery type of battery 1 is L1, the interface type of battery 1 is L1, the ID number of battery 1 is 001, the battery replenishment station information to which battery 1 belongs is battery replenishment station a, the battery type of battery 2 is L2, the interface type of battery 2 is L2, the ID number of battery 2 is 002, the battery replenishment station information to which battery 2 belongs is battery replenishment station B, the dynamic lookup table established can be as shown in table 1 below,

Step 311, the battery device receives the assigned ID number transmitted by the server.

And step 314, when the electric quantity of the battery to be monitored is smaller than a preset threshold value, the first terminal sends a query request carrying the attribute information of the battery to be monitored to the server.
It should be noted that, there is no logical sequence between the steps 313 and 314 implemented by the first terminal and the steps related to the implementation of the battery device, the steps related to the implementation of the server, and the steps related to the implementation of the second terminal, that is, the steps related to the implementation of the battery device, the server, and the second terminal may be implemented by the first terminal while the steps 313 and 314 are implemented by the first terminal.

Fig. 6 is a flow chart of another battery management method according to an embodiment of the present invention, 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 attribute information of the battery to the server.
Step 403, the server receives the attribute information of the battery transmitted by the battery device.
Step 404, the battery device obtains the charge and discharge times of the battery and the duration of the battery.
Specifically, the chip configured in the battery device stores the charge and discharge times of the battery and the duration of the battery, and the charge and discharge times of the battery and the duration of the battery can be read.
Step 405, the battery device obtains a charging history and a discharging history of the battery.
Specifically, step 405 may be implemented to obtain the charging history and the discharging history of the battery in the following manner:
step 405a, the voltage of the battery is changed from the initial voltage V k To rated voltage V n Divided into n-k intervals.
The n-k intervals are (V k ，V k+1 )、(V k+1 ，V k+2 )…(V n-1 ，V n ) The method comprises the steps of carrying out a first treatment on the surface of the k and n are positive integers, and k<n。
Step 405b, obtaining the voltage of the battery from V k Raised to V k+1 The required electric quantity Q c k From V k+1 Raised to V k+2 The required electric quantity Q c k+1 … from V n-1 Raised to V n The required electric quantity Q c n-1 The charging history of the battery is obtained.
Specifically, step 405b refers to sequentially acquiring the amount of power required for charging the battery in a plurality of voltage intervals.

Specifically, step 405c refers to sequentially obtaining the electric quantity obtained by discharging the battery in a plurality of voltage intervals.
Step 406, the battery device calculates an average charge/discharge ratio of the battery according to the charge history and the discharge history.
The average charge/discharge ratio of the battery reflects the performance of the battery. Assuming that the battery needs Q1 power from voltage V1 to voltage V2, and the voltage decreases from V2 to V1 to obtain Q2 power, Q2 tends to be smaller than Q1 due to a certain power loss of the battery itself, and the amount of Q2 smaller than Q1 is affected by the performance of the battery, it is necessary to calculate the average charge-discharge ratio of the battery to reflect the performance of the battery.
Specifically, the step 406 of calculating the average charge-discharge ratio of the battery according to the charge history and the discharge history by the battery device may be implemented by the following ways:
Step 406a1 according to Q c i And Q d i Calculated to obtain the battery (V i ，V i+1 ) Charge-discharge ratio E of interval i 。
I=k, k+ … n-1. Charge-discharge ratio E i Refers to the battery at (V i ，V i+1 ) The interval (V) obtained by charging and discharging the battery at the latest time i ，V i+1 ) Charge-discharge ratio of the section.
In particular, the battery (V i ，V i+1 ) Charge-discharge ratio E of interval i ＝Q d i /Q c i 。
Specifically, the battery voltage may be determined based on the battery voltage (V i ，V i+1 ) The charge-discharge ratio obtained by charging and discharging for the first time and the charge-discharge ratio … obtained by charging and discharging for the second time in the interval until the last timeThe charge-discharge ratio obtained by charging and discharging the row is plotted as (V i ，V i+1 ) And the charge-discharge proportion curve of the interval is used as a judging standard of the battery quality.
Step 406b1 according to E k 、E k+1 ...E n Calculating to obtain the average charge-discharge ratio E of the battery (k,n) 。
Specifically, the average charge-discharge ratio of the battery
Or alternatively, the process may be performed,
step 406a2 according to Q c i And Q d i Calculated to obtain the battery (V i ，V i+1 ) Charge-discharge ratio E of interval i 。
I=k, k+ … n-1.
Step 406b2 according to E k 、E k+1 ...E n And a preset proportional weight value w k 、w k+1 …w n Calculating to obtain the average charge-discharge ratio E of the battery (k,n) 。
It should be noted that, the preset proportional weight value w k 、w k+1 …w n Is preset, w k +w k+1 +…+w n =1. Since the reference value of the charge-discharge ratio of the voltage in the lower range section and the higher range section is slightly lower, the weight value w is generally k And w n Relative to other weight values w k+1 …w n-1 Smaller.
Specifically, the average charge-discharge ratio of the battery

Step 409, the server determines the level of the battery according to the preset standard and the average charge-discharge ratio of the battery.
The preset standard is preset according to a specific case.
Specifically, assuming that the preset standard is that the battery with the average charge ratio of 90% or more is the a-class, the battery with the average charge ratio of 70% or more and less than 90% is the B-class, and the battery with the average charge ratio of 70% or less is the C-class, the class of the battery can be determined according to such a preset standard and the average charge/discharge ratio of a certain battery.
