The identification module may include, but is not limited to, a single chip microcomputer, a chip, etc. having a data transmission function and a calculation function. Wherein, the wireless communication link may be LoRa, bluetooth or Zigbee, etc. LoRa is one of the low power wan network communication technologies. ZigBee is a low-power consumption local area network protocol based on IEEE802.15.4 standard, and is a short-distance and low-power consumption wireless communication technology.
The first voltage sensor 130 may be used to measure a first voltage at the output of the charger 110.

The first current sensor 140 may be used to measure a first current at the output of the charger 110.

The first current sensor 140 may include, but is not limited to, a shunt, a fiber optic current sensor, a hall current sensor, and the like.
The battery pack 150 to be charged may be a battery pack formed by combining a plurality of lead-acid battery cells in series and/or in parallel. In practical situations, the power storage batteries which can be used in mines include a lead-acid storage battery and a lithium battery, and the lithium battery has high charging danger degree in mines containing combustible gas such as gas and coal dust explosive environment due to strong activity and poor stability. And the lead-acid storage battery has stable voltage, so that various large-scale equipment used in the mine production operation process can be charged in a mine.
The identification card 160 may store the identification information of the battery pack 150 to be charged, such as identification, specification, and the like, in the memory, and has a communication function. In practice, one battery pack 150 to be charged corresponds to one identification card 160. The identification card 160 may be in wireless communication with the identification module 120.
The second voltage sensor 170 may be used to measure the voltage at the input of the candidate battery pack to be charged for the charging test.

The second voltage sensor 170 may include, but is not limited to, a hall voltage sensor, a direct current voltage sensor, a voltage signal sensor, and the like. The second current sensor 180 may be used to measure the current at the input of the candidate battery pack to be charged for the charging test. For the sake of convenience of distinction, the current at the input end of the candidate to-be-charged storage battery pack for performing the charging test may be referred to as a second current. The second current sensor 180 may include, but is not limited to, a shunt, a fiber optic current sensor, a hall current sensor, and the like.
It should be understood that the number of chargers, identification modules, first voltage sensors, first current sensors, battery packs to be charged, identification cards, second voltage sensors and second current sensors in fig. 1 are merely illustrative. According to the implementation requirement, any number of chargers, identification modules, first voltage sensors, first current sensors, storage battery packs to be charged, identification cards, second voltage sensors and second current sensors can be provided.
In this embodiment, the identification module 120 has a wireless communication function, and is configured to receive, through wireless communication, parameter information of each storage battery pack sent by each identification card corresponding to each storage battery pack, where each storage battery pack corresponds to one identification card; when detecting that a storage battery pack is connected with a charger, determining at least one candidate storage battery pack to be charged according to parameter information of each storage battery pack; and sequentially carrying out charging test on at least one candidate storage battery pack to be charged by using the charger 110.
A first voltage sensor 130, configured to measure a first voltage at an output terminal of the charger 110; the first current sensor 140 is used for measuring a first current at the output terminal of the charger 110.
A second voltage sensor 170 for measuring a second voltage at the input terminal of the candidate battery pack to be charged for the charge test; and the second current sensor 180 is used for measuring a second current at the input end of the candidate to-be-charged storage battery pack for performing the charging test.
The identification module 120 is further configured to obtain a first voltage and a first current, and receive a second voltage and a second current sent by an identification card corresponding to a candidate to-be-charged storage battery pack for performing a charging test; and identifying the storage battery pack 150 to be charged from at least one candidate storage battery pack to be charged according to the difference value between the first voltage and the second voltage and the difference value between the first current and the second current, wherein the storage battery pack 150 to be charged is the storage battery pack currently connected with the charger.
Because the charger can meet the charging requirements of the storage battery packs with various specifications and models, and the charger can be in wireless communication with the storage battery packs, if the charger can only charge one storage battery pack, when the storage battery pack is detected to be connected with the charger, the identification module cannot determine which storage battery pack is connected with the charger. Therefore, when the storage battery pack is detected to be connected with the charger, at least one candidate storage battery pack to be charged can be determined according to the parameter information of each storage battery pack. Therefore, whether the candidate storage battery pack to be charged is the storage battery pack currently connected with the charger or not, namely the storage battery pack to be charged is determined by performing a charging test on at least one candidate storage battery pack to be charged.
For example, each storage battery pack corresponds to one identification card, parameter information of the corresponding storage battery pack is stored in each identification card, and 5 storage battery packs are arranged in a preset range from a charger. The identification module can receive parameter information of each storage battery pack sent by each identification card corresponding to 5 storage battery packs through wireless communication. When the storage battery pack is detected to be connected with the charger, the identification module determines that 3 candidate storage battery packs to be charged are a, b and c respectively according to the parameter information of each storage battery pack. When the charging test is performed, the charging test can be performed on the storage battery pack a first, so as to obtain a first voltage, a first current, a second voltage and a second current corresponding to the storage battery pack a, and determine whether the storage battery pack a is a storage battery pack to be charged. If the storage battery pack a is not the storage battery pack to be charged, a charging test can be performed on the storage battery pack b to obtain a first voltage, a first current, a second voltage and a second current corresponding to the storage battery pack b, and whether the storage battery pack b is the storage battery pack to be charged is judged.
In one embodiment of the present application, the parameter information may include a present voltage,
the first voltage sensor 130 is further configured to measure a third voltage when detecting that the battery pack is connected to the charger 110;
the identifying module 120 is configured to determine any battery pack as a candidate battery pack to be charged, when a difference between a current voltage and a third voltage of any battery pack is smaller than a first preset voltage threshold. The third voltage may be measured when it is detected that the battery pack is connected to the charger.
As an example, when it is detected that a battery pack is connected to the charger and the measured voltage is 200V, the battery pack having the current voltage close to 200V, for example, the battery pack having the current voltage in the range of [195v,205v ], may be determined as the candidate battery pack to be charged.
It should be noted that the first preset current threshold may be set as needed, and the application is not limited thereto.
In one embodiment of the present application, the identification module 120 is configured to:
and under the condition that the difference value between the first voltage and the second voltage corresponding to any candidate battery pack to be charged is smaller than a second preset voltage threshold value, and the difference value between the corresponding first current and the second current is smaller than a first preset current threshold value, determining any candidate battery pack to be charged as the battery pack to be charged 150.
As an example, when the difference between the first voltage and the second voltage corresponding to a candidate to-be-charged battery pack is 1 volt and is smaller than the second preset voltage threshold 1.5 volts, and the difference between the first current and the second current corresponding to the candidate to-be-charged battery pack is 1 ampere and is smaller than the first preset current threshold 1.2 amperes, the candidate to-be-charged battery pack may be considered as the to-be-charged battery pack.
In a possible implementation manner of the embodiment of the present application, the identification module 120 is configured to sequentially send a test instruction to the charger 110.
The charger 110 is used for receiving a test instruction; and performing a charging test on the candidate storage battery pack to be charged by using the current smaller than the second preset current threshold according to the test instruction.
The test instruction can be sent to the charger in a data packet mode through a wireless communication mode.
For example, the second preset current threshold is 2 amperes, the charger may receive a data packet including a test instruction, and perform a charging test on the candidate to-be-charged storage battery pack with a current smaller than 2 amperes according to the data packet.
It should be noted that the second preset current threshold may be set according to actual needs, which is not limited in this application.
In an embodiment of the present application, the identifying module 120 is further configured to:
under the condition that the storage battery pack 150 to be charged is not matched with the charger 110, determining the adjusted charging parameters according to the type information corresponding to the storage battery pack 110 to be charged;
sending a charging instruction to the charger 110, wherein the charging instruction includes the adjusted charging parameters;
the charger 110 is configured to receive a charging instruction; and charging the storage battery pack 150 to be charged according to the adjusted charging parameters included in the charging instruction.
Fig. 2 is a schematic diagram of a charger according to an embodiment of the present application for charging mining storage batteries of different specifications and models.
In fig. 2, if the current battery pack to be charged is an a-type battery pack, the a-type battery pack is matched with the charger a, so that the charger a can be controlled to directly charge the a-type battery pack. When the storage battery pack to be charged is any one of a B-type storage battery pack to an N-type storage battery pack, the charging parameter is adjusted because the storage battery pack to be charged is not matched with the charger A.
The system embodiment corresponds to the method embodiment, and has the same technical effect as the method embodiment, and for the specific description, reference is made to the method embodiment. The system embodiment corresponds to the method embodiment, and for the specific description, reference may be made to the method embodiment section, which is not described herein again.
According to the identification system of the mining storage battery pack, when the storage battery pack is detected to be connected with the charger according to the parameter information of the storage battery pack sent by the identification cards corresponding to the storage battery packs received through wireless communication, at least one candidate storage battery pack to be charged is determined, then the charger is used for conducting charging test on the at least one candidate storage battery pack to be charged in sequence to obtain first voltage and first current at the output end of the charger, and second voltage and second current sent by the identification cards corresponding to the candidate storage batteries to be charged for conducting the charging test are received through wireless communication, so that the storage battery pack to be charged is identified from the at least one candidate storage battery pack to be charged according to the difference between the first voltage and the second voltage and the difference between the first current and the second current, therefore automatic identification of the mining storage battery pack is achieved, workload of underground workers is reduced, and identification efficiency is improved.

As shown in fig. 4, the identification method of the mining storage battery pack includes:
step 201, receiving parameter information of each storage battery pack sent by each identification card corresponding to each storage battery pack through wireless communication.
In the application, each storage battery pack can correspond to one identification card, and the computing equipment can receive the parameter information of each storage battery pack sent by each identification card corresponding to each storage battery pack in a wireless communication connection mode.
The wireless communication can utilize wireless communication technologies such as LoRa, bluetooth or Zigbee to perform information interaction. The storage battery pack can be formed by combining a plurality of lead-acid storage battery single cells in series and/or parallel.

The battery usage period may be a period of time from the last charge of the battery to the current point in time.
As an example, the computing device may receive, through bluetooth technology, battery usage time information of each storage battery pack sent by each identification card corresponding to each storage battery pack.
Step 202, when it is detected that the storage battery pack is connected with the charger, at least one candidate storage battery pack to be charged is determined according to the parameter information of each storage battery pack.
In this application, the computing device may determine at least one candidate battery pack to be charged according to parameter information of each battery pack when it is detected that the battery pack is connected to the charger. The candidate rechargeable battery pack may be a battery pack that may need to be charged.
Because the charger can meet the charging requirements of the storage battery packs with various specifications and models, and the charger can be in wireless communication with the storage battery packs, if the charger can only charge one storage battery pack, when the storage battery pack is detected to be connected with the charger, the identification module cannot determine which storage battery pack is connected with the charger. Therefore, when the storage battery pack is detected to be connected with the charger, at least one candidate storage battery pack to be charged can be determined according to the parameter information of each storage battery pack. Therefore, whether the candidate storage battery pack to be charged is the storage battery pack currently connected with the charger or not, namely the storage battery pack to be charged is determined by performing a charging test on at least one candidate storage battery pack to be charged.
And 203, sequentially carrying out a charging test on at least one candidate battery pack to be charged by using the charger to obtain a first voltage and a first current at the output end of the charger, and receiving a second voltage and a second current sent by an identification card corresponding to the candidate battery pack to be charged for carrying out the charging test through wireless communication.

The charging test may be charging at a preset current to obtain voltage and current information, for example, the preset current may be 0.5 ampere.

In step 606, the identification module determines whether (Uc-Ub < a 1) & (Ic-Ib < a 2) is satisfied. A1 may represent a difference between a first voltage Uc at the output end of the charger and a second voltage Ub received by wireless communication and sent by an identification card corresponding to a candidate battery to be charged for performing a charging test at a certain time. a2 may represent a difference value between the first current Ic at the output end of the charger and the second current Ib sent by the identification card corresponding to the candidate battery to be charged for performing the charging test received through wireless communication at a certain moment.
And if the first voltage Uc, the first current Ic, the second voltage Ub and the second current Ib of the first candidate storage battery pack to be charged are measured to meet the condition (Uc-Ub < a 1) & (Ic-Ib < a 2), the first candidate storage battery pack to be charged is considered as the storage battery pack to be charged, and if the first voltage Uc, the first current Ic, the second voltage Ub and the second current Ib of the first candidate storage battery pack to be charged are measured to not meet the condition (Uc-Ub < a 1) & (Ic-Ib < a 2), the (n + 1) th candidate storage battery pack to be charged is locked, and judgment and identification are carried out.
