DETAILED DESCRIPTION

[0054] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0055] The following is an explanation of some of the names involved in this application:

[0056] Battery charging and discharging equipment: generally refers to equipment or systems that can control the battery charging and discharging process. These devices are widely used in various fields, including electronic devices, energy storage systems, electric vehicles, etc. Their main functions include managing the battery's charge state and providing energy to devices that require electrical energy.

[0057] At present, the performance test method for battery charging and discharging equipment usually requires manual use of different testing equipment to test various parameters of the battery charging and discharging equipment in turn. For example, the tester first uses the equipment to detect the voltage value of the battery charging and discharging equipment, and then manually determines whether the difference between it and the reference voltage value exceeds the preset difference. If it exceeds, the parameter value is calibrated. For different parameters, the staff needs to manually test and calibrate them one by one, which is cumbersome to operate and has low detection efficiency.

[0058] The inventors considered that if a system could be designed that could automatically calibrate battery charging and discharging equipment, it would improve detection efficiency and save manpower.

[0059] In view of this, the present application provides a battery charging and discharging equipment detection system, which can detect whether the parameters of the target channel of the battery charging and discharging equipment need to be calibrated, and automatically calibrate the parameters when it is determined that calibration is required. The whole process is automated, the operation is simplified, the detection efficiency is improved, and human resources are saved.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0061] Figure 1 A schematic structural diagram of a first battery charging and discharging equipment detection system provided in the present application, comprising: a control module 11, a detection module 12, and a switch module 13;

[0062] The control module 11 is connected to the switch module 13 and the detection module 12; the switch module 13 is connected to the detection module 12 and the battery charging and discharging device. The control module 11 is connected to the switch module 13 and the detection module 12; the switch module 13 is connected to the detection module 12 and the battery charging and discharging device.

[0063] The control module 11 may include, for example, any processing chip with a control function. The switch module 13 may include, for example, at least one relay, or other switches. When relays are included, the number of relays included is related to the number of parameters of battery charging and discharging devices that can be detected by the battery charging and discharging device detection system 1. In some embodiments, the control module 11 may control the detection and calibration of different parameters by controlling the closing of switches corresponding to different detection parameters in the switch module 13.

[0064] In some embodiments, when the switch module 13 includes at least one relay, the control module 11 may include, for example, a relay control unit and an industrial computer control unit; the relay control unit and the industrial computer control unit, as well as the relay are connected; the industrial computer control unit is used to control the state of the relay through the relay control unit. The industrial computer control unit may include, for example, a main control chip, and the relay control unit may include, for example, a chip for controlling the state of the relay. This application does not limit the types of the above chips. The relay control unit is used to control the relay, and realizes the function of switching the detection module 12 to detect the mode, and automatically realizes the logical function.

[0065] The detection module 12 is used to provide a standard voltage reference and current reference, and may include a multimeter 121, for example, to detect various parameters to be detected of the battery charging and discharging device. Alternatively, the device included in the detection module 12 is related to the parameters that the battery charging and discharging device detection system 1 is specifically used to detect. Exemplarily, if the battery charging and discharging device detection system 1 is used to detect the current of the battery charging and discharging device, the detection module 12 may include, for example, a Hall current sensor 122. If the battery charging and discharging device detection system 1 is also used to detect the voltage of the battery charging and discharging device, the detection module 12 may include, for example, a voltmeter.

[0066] The battery charging and discharging device mentioned above is the device to be tested, which is the object to be calibrated and is also the load that provides a bidirectional constant voltage source for generating a current loop.

[0067] In the above implementation, the present application provides a battery charging and discharging equipment detection method, which is applied to the control module 11 of the battery charging and discharging equipment detection system 1. Figure 2 A flow chart of a battery charging and discharging equipment detection method provided in this application, such as Figure 2As shown, the method comprises the following steps:

[0068] S101 , in response to a verification request for a target parameter of a target channel of a battery charging and discharging device, controlling a switch module 13 corresponding to the target parameter to close, and using a detection module 12 to obtain an actual value of the target parameter of the target channel.

[0069] The target channel is a channel for the battery charging and discharging device to obtain or output voltage / current. The response to the verification request for the target parameter of the target channel of the battery charging and discharging device mentioned here can be, for example, obtaining the verification request for the target parameter of the target channel issued by the user by clicking the control button of the battery charging and discharging device detection system 1.

[0070] The target parameters may include, for example, one or more of the following: current parameter, voltage parameter, temperature parameter, pressure parameter. Each target parameter corresponds to a switch module 13. When the control module 11 controls the switch module 13 corresponding to the target parameter to be closed, the target parameter of the target channel of the battery charging and discharging device is detected and calibrated accordingly.

[0071] Exemplarily, the detection module 12 may include a multimeter 121. When the switch module 13 corresponding to the target parameter is closed, the multimeter 121 may be used to obtain the actual value of the target parameter of the target channel.

[0072] S102: Determine whether the difference between the actual value of the target parameter and the reference value of the target parameter exceeds a preset difference threshold corresponding to the target parameter.

[0073] The present application does not limit the specific value of the preset difference threshold, and those skilled in the art can set it according to the requirements. In this step, the control module 11 determines whether the difference between the actual value of the target parameter and the reference value of the target parameter exceeds the preset difference threshold corresponding to the target parameter, so as to control the difference between the actual value of the target parameter and the reference value of the target parameter within the preset difference threshold range.

[0074] If yes, execute step S103.

[0075] S103: Send the actual value of the target parameter to the battery charging and discharging device to calibrate the target parameter.

[0076] In this step, the actual value of the target parameter of the control module 11 is sent to the battery charging and discharging device to calibrate the target parameter, thereby ensuring the availability of the battery charging and discharging device.

[0077] In this embodiment, the battery charging and discharging equipment detection system 1 includes: a control module 11, a detection module 12, and a switch module 13; the control module 11 is connected to the switch module 13 and the detection module 12; the switch module 13 is connected to the detection module 12 and the battery charging and discharging equipment; the control module 11 is configured to: in response to a verification request for a target parameter of a target channel of the battery charging and discharging equipment, control the switch module 13 corresponding to the target parameter to be closed, and use the detection module 12 to obtain the actual value of the target parameter of the target channel; determine whether the difference between the actual value of the target parameter and the reference value of the target parameter exceeds the preset difference threshold corresponding to the target parameter; if so, send the actual value of the target parameter to the battery charging and discharging equipment to calibrate the target parameter. Through this implementation, the battery charging and discharging equipment detection system 1 can automatically detect whether each parameter of the battery charging and discharging equipment needs to be calibrated, and automatically calibrate the parameter when it is determined that detection is required. Compared with the manual accuracy judgment and calibration method in the prior art, the efficiency of detection and calibration can be improved and human resources can be reduced.

[0078] The following is an illustrative description of how the battery charging and discharging equipment detection system 1 detects different target parameters of a target channel through a specific embodiment.

[0079] Figure 3 The structural diagram of the second battery charging and discharging equipment detection system provided in this application is as follows: Figure 3 As shown, when the target parameter includes a voltage parameter and the detection module 12 includes a multimeter 121 , the switch module 13 may include, for example, a first relay 131 .

[0080] The first end of the first relay 131 is connected to the voltage detection interface of the multimeter 121 , and the second end of the first relay 131 is connected to the control module 11 .

[0081] When the third terminal of the first relay 131 is connected to the target channel of the battery charging and discharging device, the control module 11 can, for example, respond to a voltage parameter verification request for the target channel of the charging and discharging device, control the multimeter 121 to be in voltage acquisition mode, and control the first relay 131 to be closed to generate a voltage loop. It should be understood that at this time, the target channel of the battery charging and discharging device outputs a constant voltage value.

[0082] At this time, the control module 11 obtains the voltage value reading of the multimeter 121 after the first relay 131 is closed as the actual value of the voltage parameter. Subsequently, the control module 11 determines whether the difference between the actual value of the voltage parameter and the reference value of the voltage parameter exceeds the preset difference threshold corresponding to the voltage parameter. If so, the actual value of the voltage parameter is sent to the battery charging and discharging device to calibrate the voltage parameter.

[0083] In this implementation mode, the battery charging and discharging device can automatically detect and calibrate the voltage of the target channel after obtaining a verification request for the voltage parameters of the target channel of the charging and discharging device, thereby improving the convenience of operation and detection efficiency.

[0084] Continue to refer to Figure 3 , when the target parameter includes a current parameter; the detection module 12 may include a Hall current sensor 122 while including a multimeter 121; the switch module 13 includes a second relay 132 and a third relay 133. The first end of the second relay 132 is connected to the first current acquisition interface of the multimeter 121, the second end is connected to the first end of the Hall current sensor 122, and the third end is connected to the control module 11; the first end of the third relay 133 is connected to the second current acquisition interface of the multimeter 121, the second end is connected to the control module 11, and the third end is connected to the constant voltage channel of the battery charging and discharging device.

[0085] The first current acquisition interface is an interface of the multimeter 121 for detecting the circuit current, and is used to obtain a constant current. The second current acquisition interface is used to obtain a constant voltage. The constant voltage channel is a channel for outputting a constant voltage. The target channel is used to output a constant current.

[0086] When the second end of the Hall current sensor 122 is connected to the target channel of the battery charging and discharging device, and the target channel outputs a constant current, the control module 11 can respond to a request for verification of the current parameters of the target channel of the battery charging and discharging device, control the multimeter 121 to the current acquisition mode, and control the second relay 132 and the third relay 133 to be closed; then obtain the current value reading of the multimeter 121 after the second relay 132 and the third relay 133 are closed as the actual value of the voltage parameter of the target channel.

[0087] Subsequently, the control module 11 determines whether the difference between the actual value of the current parameter and the reference value exceeds a preset difference threshold corresponding to the current parameter. If so, the actual value of the current parameter is sent to the battery charging and discharging device to calibrate the current parameter of the target channel.

[0088] In this implementation, the battery charging and discharging device can automatically detect and calibrate the current of the target channel after obtaining a verification request for the current parameters of the target channel of the charging and discharging device, thereby improving the convenience of operation and detection efficiency. In addition, in this implementation, by connecting the Hall current sensor 122 to the multimeter 121, a high-precision current reference can be provided, and it has the advantages of small temperature drift, small residual magnetic flux, and small zero drift.

[0089] Optionally, in some embodiments, continue to refer to Figure 3The battery charging and discharging equipment detection system 1 may further include an analog output module 14. Optionally, if the target parameter includes a temperature parameter, the analog output module 14 may include, for example, a temperature analog output unit 1411; if the target parameter includes a pressure parameter, the analog output module 14 may include, for example, a pressure analog output unit 142. The temperature analog output unit 1411 may be, for example, a temperature analog output board. The pressure analog output unit 142 may be, for example, a pressure analog output board.

[0090] Continue to refer to Figure 3 When the target parameter includes a temperature parameter, the analog output module 14 may, for example, include a temperature analog output unit 141, and the switch module 13 also includes a fourth relay 134; a first end of the fourth relay 134 is connected to the impedance acquisition interface of the multimeter 121, a second end is connected to the first end of the temperature analog output unit 141, and a third end is connected to the control module 11; a second end of the temperature analog output unit 141 is connected to the control module 11.

[0091] The temperature simulation output unit 141 may include, for example, a temperature simulation board for providing an impedance value and cooperating with the multimeter 121 to implement temperature calibration.

[0092] When the third end of the temperature analog output unit 141 is connected to the target channel of the battery charging and discharging device, the control module 11 can respond to the calibration request for the temperature parameter of the target channel of the battery charging and discharging device, control the multimeter 121 to the impedance acquisition mode, and control the fourth relay 134 to be closed; after the self-calibration of the temperature analog output unit 141 is completed, control the temperature analog output unit 141 to output the target impedance; and use the temperature corresponding to the impedance measurement value of the multimeter 121 as the actual value of the temperature parameter of the target channel.

[0093] The present application does not limit the specific resistance value of the above target impedance. The control module 11 can control the multimeter 121 to self-calibrate the temperature analog output unit 141. The present application does not limit the method of controlling the multimeter 121 to self-calibrate the temperature analog output unit 141. For details, reference can be made to the prior art and will not be repeated here.

[0094] Exemplarily, the control module 11 may store a temperature characteristic table (RT table) representing the mapping relationship between impedance and temperature, and determine the temperature corresponding to the impedance measurement value measured by the multimeter 121 based on the RT table.

[0095] Subsequently, the control module 11 can, for example, determine the difference between the actual value of the target temperature of the target channel and the reference value. When the difference exceeds the preset difference threshold corresponding to the temperature parameter, it is determined that the temperature parameter of the target channel needs to be calibrated, and the reference value is sent to the battery charging and discharging device to achieve temperature calibration of the battery charging and discharging device.

[0096] Through this implementation method, automatic detection and calibration of the temperature parameters of the battery charging and discharging equipment can be achieved, the operation steps are simplified, and the detection efficiency of the temperature parameters of the battery charging and discharging equipment is improved.

[0097] Basic reference Figure 3 , when the target parameter includes a pressure parameter; the analog output module 14 may include, for example, a pressure analog output unit 142, and the switch module 13 includes a fifth relay 135. The first end of the fifth relay 135 is connected to the voltage detection interface of the multimeter 121, the second end is connected to the first end of the pressure analog output unit 142, and the third end is connected to the control module 11; the second end of the pressure analog output unit 142 is connected to the control module 11.

[0098] The pressure simulation output unit 142 may include, for example, a pressure simulation board for providing a pressure simulation source and collecting pressure excitations to achieve calibration of pressure parameters.

[0099] When the third end of the pressure simulation output unit 142 is connected to the target channel of the battery charging and discharging device, the control module 11 can control the fifth relay 135 to close in response to a verification request for the pressure parameters of the target channel of the battery charging and discharging device; control the multimeter 121 to switch to the pressure inspection mode, and obtain the excitation voltage obtained by the multimeter 121 after the fifth relay 135 is closed as the actual value of the pressure parameter of the target channel. Control the multimeter 121 to switch to the pressure inspection mode, and obtain the excitation voltage obtained by the multimeter 121 after the fifth relay 135 is closed; after obtaining the excitation voltage, control the multimeter 121 to switch to the analog voltage acquisition mode to obtain the analog voltage output by the pressure simulation output unit 142; according to the excitation voltage and the analog voltage, obtain the actual value of the pressure parameter. The specific calculation method can refer to the prior art and will not be repeated here.

[0100] Optionally, the control module 11 can adopt a three-stage voltage division output mode to provide a simulated pressure value of the midpoint common mode voltage when calibrating the pressure parameters. Optionally, the control module 11 can also respond to the user's pressure adjustment request for the pressure simulation output unit 142 and change the analog output value to meet the calibration and verification requirements.

[0101] Through this implementation method, automatic detection and calibration of the pressure parameters of the battery charging and discharging equipment can be achieved, the operation steps are simplified, and the detection efficiency of the pressure parameters of the battery charging and discharging equipment is improved.

[0102] Optionally, when the battery charging and discharging equipment is calibrating the temperature and pressure parameters, a patrol method can be used to obtain the analog values ​​of the temperature simulation board and the pressure simulation board to automatically couple the calibration values ​​of other channels, thereby greatly improving the calibration efficiency.

[0103] Optionally, in some embodiments, after obtaining a verification request for the voltage parameters of the target channel of the charging and discharging device, the control module 11 may first perform a system self-check, and only perform detection and calibration of the target parameters after the self-check is qualified. If the self-check fails, an alarm message is output and the detection of the battery charging and discharging device is terminated.

[0104] Alternatively, in some embodiments, after obtaining a verification request for the voltage parameters of the target channel of the charging and discharging device, the control module 11 can send a calibration plan for the target parameter to the battery charging and discharging device after the self-test is completed. The battery charging and discharging device controls the target channel to output the actual value of the parameter to be detected according to the calibration plan.

[0105] Optionally, the calibration data and the calibrated data can be automatically generated into reports, and the unsatisfactory accuracy can also be presented to the user in a prominent manner through reports. For points that fail calibration and verification, supplementary calibration or verification can be performed through manual calibration and verification of single points, so as to realize quick and convenient calibration.
