Therefore, the test equipment is directly controlled to perform mutual complementary discharge test on the batteries according to the charge and discharge complementary parameter information. When it does not meet the requirements, it is determined that some batteries cannot be matched. Therefore, the test equipment is controlled to perform charge and discharge test on the unmatched batteries according to the weak match parameter information and the supplementary parameter information, thereby saving energy and further improving the environmental friendliness of the battery test.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The processing terminal is connected with multiple network ports and various parts of the test device to form a distributed control system. After the processing terminal receives the test trigger information of the battery, the test device is controlled to detect the battery connection direction information and battery status information of the battery. The processing terminal determines the test sequence information of the battery according to the battery status information and the status test relationship information, thereby controlling the test device to perform charge and discharge tests on the battery according to the battery connection direction information and the test sequence information, and the battery will not be unable to be tested due to the battery being placed upside down, thereby improving the convenience of battery testing.
[0036] Reference Figure 1 The present application embodiment discloses a bidirectional battery testing method, comprising the following steps: Step S100: Acquire battery test trigger information.
[0037] Among them, the test trigger information refers to the trigger data indicating that the battery can be charged and discharged. In one embodiment, after the operator connects the battery to the test equipment, the operator makes a selection in the graphical interface of the processing terminal; in another embodiment, the photoelectric sensing device installed at the battery connection of the test equipment can sense and output the test trigger information to the processing terminal.
[0038] Step S101: obtaining battery connection direction information and battery status information of the battery according to the test trigger information.
[0039] Among them, the battery connection direction information refers to the direction in which the battery is connected to the test equipment, including forward connection and reverse connection. Forward connection means that the positive electrode of the battery is connected to the positive electrode of the test equipment, and the negative electrode of the battery is connected to the negative electrode of the test equipment; reverse connection means that the positive electrode of the battery is connected to the negative electrode of the test equipment, and the negative electrode of the battery is connected to the positive electrode of the test equipment. After the processing terminal receives the test trigger information, the processing terminal controls the camera on the test equipment to shoot and identify the positive and negative electrode symbols on the battery at the connection and the positive and negative electrode symbols on the test equipment. Battery status information refers to the energy status of the battery, including powered and unpowered, which is selected and determined by the operator in the graphical interface of the processing terminal and called by the processing terminal.
[0040] Step S102: determining battery test sequence information according to battery status information and preset status test relationship information.
[0041] Among them, the status test relationship information refers to a database that stores the correspondence between the battery status and the order of test items. When the battery status is charged, the discharge test is performed first, and then the charging test; when the battery status is empty, the charging test is performed first, and then the discharge test is performed. The operator will correspond the two and store them in the database.
[0042] The test sequence information refers to the order of items for testing the battery, which is obtained by matching the status input corresponding to the battery status information into the database corresponding to the status test relationship information by the processing terminal. For example, if the battery status is charged, the test sequence information is to perform a discharge test first and then a charge test; when the battery status is empty, the test sequence information is to perform a charge test first and then a discharge test.
[0043] Step S103: controlling a preset test device to test the battery according to the battery connection direction information and the test sequence information.
[0044] Among them, the test equipment refers to equipment that can perform charging and discharging tests on batteries, including a slave control unit for controlling the test equipment to perform specific tasks, an analog-to-digital converter for high-precision acquisition of battery voltage or current signals, a digital-to-analog converter for setting test parameters, and a battery charge and discharge control circuit for controlling the precise charging and discharging of the battery. After the processing terminal determines the battery connection direction information and the test sequence information, the control test equipment determines and processes the battery connection direction information, and then performs charge and discharge tests on the battery according to the order corresponding to the test sequence information. For specific methods, refer to Figure 2 The steps are as follows, so that the battery charge and discharge test can be completed without the need for personnel to adjust the connection direction of the battery, thereby improving the convenience of battery testing.
[0045] Reference Figure 2 The steps of controlling a preset test device to test the battery according to the battery connection direction information and the test sequence information include: Step S200: determining whether the battery connection direction information meets the requirements of the preset test direction information.
[0046] Among them, the test direction information refers to the direction of normal charge and discharge test on the battery, that is, the positive electrode is connected to the positive electrode, and the negative electrode is connected to the negative electrode. The requirement of the test direction information is that it is consistent with the direction corresponding to the test direction information, and is stored in the processing terminal by the operator.
[0047] The processing terminal determines whether the connection direction corresponding to the battery connection direction information is consistent with the direction corresponding to the test direction information, thereby determining whether the battery connection direction can be directly used for charge and discharge testing.
[0048] Step S201: If not, controlling a preset direction adjustment circuit to adjust the battery connection direction information of the battery, and outputting preset test start trigger information.
[0049] Among them, if the processing terminal determines that the connection direction corresponding to the battery connection direction information is inconsistent with the direction corresponding to the test direction information, it indicates that the positive pole of the battery is connected to the negative pole of the test equipment, and the negative pole of the battery is connected to the positive pole of the test equipment. Therefore, the control direction adjustment circuit adjusts the battery connection direction information of the battery, so that the positive pole of the battery is connected to the positive pole of the test equipment, and the negative pole of the battery is connected to the negative pole of the test equipment, thereby outputting the test start trigger information to provide data support for the subsequent control test equipment to perform charge and discharge tests on the battery.
[0050] The direction adjustment circuit refers to a circuit for adjusting the connection direction of the battery, including two wires connected in parallel between the positive and negative poles of the test equipment, and the positive and negative poles of the battery are connected to the two wires respectively, and four electric control switches are respectively arranged on the two wires, and the electric control switches are respectively located on both sides of the center line of the two wires with the battery as the center line, so that when the two switches symmetrical about the center of the battery are closed, one end of the battery can be controlled to be connected to the positive pole of the test equipment and the other end to the negative pole of the test equipment. The specific two switches are responsible for the correct direction and the two switches are responsible for adjusting the direction are determined by the operator according to the actual situation. The test start trigger information refers to the trigger data that can start the battery charge and discharge test, which is stored in the processing terminal in advance by the operator and output when the processing terminal determines that the connection direction of the battery is consistent with the test direction.
[0051] Step S202: If the conditions are met, output the preset test start trigger information.
[0052] Among them, if the processing terminal determines that the connection direction corresponding to the battery connection direction information is consistent with the direction corresponding to the test direction information, it means that the positive pole of the battery is connected to the positive pole of the test equipment, and the negative pole of the battery is connected to the negative pole of the test equipment. Therefore, the battery charge and discharge test can be started directly, thereby outputting the test start trigger information to provide a specific time for the subsequent test to start.
[0053] The test start trigger information in this step is consistent with the test start trigger information in step S201, and will not be described in detail here.
[0054] Step S2021: Control the test equipment to test the battery according to the test start trigger information and the test sequence information.
[0055] Among them, after the processing terminal receives the test start trigger information, the processing terminal responds to the test start trigger information, thereby controlling the test equipment to perform charge and discharge tests on the battery in the test sequence corresponding to the test sequence information. The specific method is referred to Figure 3 steps.
[0056] Reference Figure 3 The steps of controlling the test equipment to test the battery according to the test start trigger information and the test sequence information include: Step S300: obtaining battery parameter information of the battery according to the test start trigger information.
[0057] The battery parameter information refers to the approximate voltage and current required for battery charging and the approximate voltage and current during battery discharge, and is input by the operator on the processing terminal when the operator connects the battery to the test equipment.
[0058] Step S301: Analyze the battery parameter information and the test sequence information to determine the test parameter information.
[0059] Among them, the test parameter information refers to the parameters that are adjusted in sequence for the test equipment when the battery is charged and discharged. It is determined by the processing terminal after analysis based on the battery parameter information and the test sequence information. The specific method of analysis is: for example, the parameters corresponding to the battery parameter information are: the voltage range during discharge is 1 to 5 volts, and the current range is -100 amps to 100 amps; the voltage range during charging is 0 to 5 volts, and the current is -100 amps to 100 amps. If the test sequence information is to test the discharge first and then the charge, the test parameter information obtained is to adjust the test equipment to test the discharge of the battery with a voltage range of 5 volts and a current range of -100 amps to 100 amps, and then test the battery charging with a voltage of 0 to 5 volts and a current of -100 amps to 100 amps.
[0060] Step S302: Control the test equipment to test the battery according to the test parameter information, and obtain basic test data information.
[0061] After the processing terminal obtains the test parameter information, the test equipment performs a charge and discharge test on the battery according to the parameters corresponding to the test parameter information. For specific methods, refer to Figure 4 The steps are completed and the basic test data information is tested to provide data support for the subsequent control of the test equipment on the battery test.
[0062] Basic test data information refers to the detection data when the test equipment performs charge and discharge tests on the battery, including voltage and current parameters, which are collected by the analog-to-digital converter sampling circuit in the test equipment.
[0063] Step S303: Analyze the basic test data information and the preset precision adjustment trigger information to determine the precision adjustment data information.
[0064] Among them, the precision adjustment trigger information refers to the trigger data for adjusting the parameters of the test equipment to make the test equipment more accurate, which is stored in the processing terminal by the operator. The precision adjustment data information refers to the data for adjusting the test parameters of the test equipment, including the voltage and current ranges during the discharge test and the number of channels during the charging test, etc., which are determined by the processing terminal in response to the precision adjustment trigger information and analyzed according to the basic test data information. The specific analysis method is: the data corresponding to the basic test data information is the voltage and current of the discharge test, and the highest precision range is determined according to the voltage and current to obtain the adjustment data during the discharge; the data corresponding to the basic test data information is the current of the charging test, and the number of channels in parallel is determined according to the current. The smaller the current, the fewer the number of channels, which can meet different test requirements, thereby obtaining the adjustment data during the charging.
[0065] Step S304: Controlling the test equipment to test the battery according to the accuracy adjustment data information to generate accurate test data information.
[0066] Among them, after the processing terminal determines the accuracy adjustment data information, it controls the test equipment to perform charge and discharge tests on the battery with the range or number of channels corresponding to the accuracy adjustment data information, so that the battery discharge test accuracy is higher and the battery charging test energy consumption is less.
[0067] Precision test data information refers to test data collected by the test equipment after adjusting the test parameters according to the adjustment data corresponding to the precision adjustment data information, including voltage and current parameters, which are collected by the analog-to-digital converter sampling circuit in the test equipment.
[0068] Reference Figure 4 The steps of controlling the test equipment to test the battery according to the test parameter information include: Step S400: Acquire test correspondence information of test parameter information.
[0069] Among them, the test correspondence information refers to the energy exchange relationship between batteries in the test parameter information, which is determined by the processing terminal after analysis based on the test parameter information. The specific analysis method is: if the batteries in the parameters corresponding to the test parameter information are first charged and then discharged, or first discharged and then charged, there is no energy exchange between the batteries, so the test correspondence information is a non-complementary relationship, otherwise the test correspondence information is a complementary relationship.
[0070] Step S401: determine whether the test correspondence relationship information meets the requirements of preset complementary test relationship information.
[0071] The complementary test relationship information refers to the complementary relationship between the test batteries that can exchange energy, and the requirement of the complementary test relationship information refers to the consistency of the complementary relationship corresponding to the complementary test relationship information, which is stored in the processing terminal by the operator.
[0072] The processing terminal determines whether the battery relationship corresponding to the test correspondence information is consistent with the complementary relationship corresponding to the complementary test relationship information, thereby determining whether energy exchange can be performed between batteries, providing data support for subsequent control test equipment to test the battery.
[0073] Step S4011: If the conditions are met, the test equipment is controlled to test the battery according to a preset charge-discharge complementary test method.
[0074] If the processing terminal determines that the battery relationship corresponding to the test correspondence information is consistent with the complementary relationship corresponding to the complementary test relationship information, it indicates that energy exchange can be performed between the batteries. Therefore, the test equipment is controlled to perform charge and discharge tests on the batteries according to the charge and discharge complementary test method. The specific method is referred to Figure 6 steps, thereby reducing energy waste in battery charge and discharge testing.
[0075] The charge-discharge complementary test method refers to a method of performing battery charge-discharge tests using the energy exchange relationship between batteries to reduce energy waste, and is stored in a processing terminal by an operator.
[0076] Step S4012: If not, control the test equipment to test the battery according to a preset charge-discharge cross test method.
[0077] If the processing terminal determines that the battery relationship corresponding to the test correspondence information is inconsistent with the complementary relationship corresponding to the complementary test relationship information, it indicates that there is no energy exchange relationship between the test batteries. Therefore, the test equipment is controlled to test the battery according to the charge and discharge cross test method. The specific method is referred to Figure 5 steps.
[0078] The charge-discharge cross-test method refers to a method of testing some batteries first and some batteries later, thereby relying on active means to form an energy exchange relationship between batteries, which is stored in the processing terminal by the operator.
[0079] Reference Figure 5 The steps of controlling the test equipment to test the battery according to the preset charge and discharge cross test method include: Step S500: Analyze the test parameter information to determine the first test parameter information and the second test parameter information.
[0080] Among them, the first test parameter information refers to the battery parameters tested first, and the second test parameter information refers to the battery parameters tested later, which are determined by the processing terminal after analyzing the parameters corresponding to the test parameter information. The specific analysis method is: if the test parameter information is all charging first and then discharging, the test parameters of half of the batteries with a higher discharge test voltage are defined as the first test parameter information, and the test parameters of the remaining half of the batteries are defined as the second test parameter information; if the test parameter information is all discharging first and then charging, the test parameters of half of the batteries with a smaller charging test voltage are defined as the first test parameter information, and the test parameters of the remaining half of the batteries are defined as the second test parameter information, thereby ensuring that half of the batteries are tested for the first time first, and energy can be exchanged between the batteries tested first and the batteries not tested in the second test.
[0081] Step S501: Analyze the pre-test parameter information and the post-test parameter information to determine the battery cross-relationship information.
[0082] Among them, the battery cross-relationship information refers to the relationship between the second test of the battery in the first test parameter information and the energy exchange between the battery in the later test parameter information, which is determined by the processing terminal after analysis based on the first test parameter information and the later test parameter information. The specific analysis method is: determine the voltage and current of the battery charging or discharging according to the test parameters corresponding to the later test parameter information, and then identify and call the voltage and current of the battery charging or discharging in the later test parameter information in the test parameters corresponding to the first test parameter information, and associate the two to obtain a pair of battery cross-relationships.
[0083] Step S502: Control the test equipment to perform a first test on the battery according to the first test parameter information, and obtain first test completion trigger information.
[0084] Among them, after the processing terminal determines the first test parameter information, the processing terminal controls the test equipment to perform the first test on the battery according to the parameters corresponding to the first test parameter information. The specific test process is a charging parameter or a discharging parameter according to the parameters corresponding to the first test parameter information. If it is a charging parameter, the energy storage battery in the test equipment supplies power according to the voltage and current corresponding to the first test parameter information. If it is a discharging parameter, the energy storage battery in the test equipment recovers the energy released by the battery discharge. After the test is completed, the first test completion trigger information is output to the processing terminal, so as to determine when to start the second test.
[0085] The first test completion trigger information refers to the trigger data of the battery completing the first test in the first test parameter information. When the test equipment determines that the voltage in the test detection data is equal to the charging cut-off voltage or the discharging cut-off voltage of the battery, the first test completion trigger information is sent to the processing terminal.
[0086] Step S503: Based on the first test completion trigger information, the test equipment is controlled to perform a second test on the battery according to the first test parameter information, the battery cross relationship information and the post test parameter information.
[0087] Among them, after the processing terminal receives the trigger information of the completion of the first test, it indicates that a part of the batteries have completed the first test, and an energy exchange relationship has been formed between the first tested batteries and the untested batteries. Therefore, the test equipment is controlled according to the second test parameters corresponding to the first test parameter information to perform a second test on the first tested batteries, and the test equipment is synchronously controlled to select the corresponding battery in the post-test parameter information according to the corresponding relationship between the batteries corresponding to the battery cross relationship to exchange energy with the tested batteries, thereby ensuring that the second test of the first tested batteries and the first test of the untested batteries are carried out normally, and reducing energy waste during the battery testing process.
[0088] Step S504: modify the post-test parameter information into the test parameter information according to the preset second test parameter modification trigger information, and supplement the new test parameter information to perform the battery test again.
[0089] Among them, after the processing terminal determines the post-test parameter information, the processing terminal modifies the trigger data corresponding to the trigger information according to the second test parameter, defines the test parameters of the second test in the post-test parameter information as the test parameter information, and supplements the test parameter information of the new battery, so that the post-tested battery completes the second test and starts testing the new battery.
[0090] The second test parameter modification trigger information refers to defining the test parameters of the second test in the post-test parameter information as test parameter information to complete the trigger data of the second test, which is stored in the processing terminal by the operator.
[0091] Reference Figure 6 The steps of controlling the test equipment to test the battery according to the preset charge-discharge complementary test method include: Step S600: Analyze the test parameter information to determine the charge-discharge complementary parameter information.
[0092] The charge-discharge complementary parameter information refers to the corresponding relationship between the energy exchange that can be performed in the first test of the battery and the corresponding relationship between the energy exchange that can be performed in the second test in the test parameter information, which is determined by the processing terminal after analyzing the parameters corresponding to the test parameter information. The specific analysis method is referred to Figure 7 steps.
[0093] Step S601: determining whether the charge-discharge complementary parameter information meets the requirement of preset complete matching trigger information.
[0094] Among them, the fully matched trigger information refers to the trigger data of the battery with which all batteries exchange energy in the first test and the second test. The requirement of the fully matched trigger information means that the fully matched trigger data corresponding to the fully matched trigger information is consistent, and is stored in the processing terminal by the operator.
[0095] By processing the terminal, it is determined whether the corresponding relationship between the charge and discharge complementary parameter information is consistent with the fully matched trigger data corresponding to the fully matched trigger information, thereby determining whether all batteries have batteries with which to exchange energy, and providing data support for subsequent control test equipment to test the batteries.
[0096] Step S6011: If it is in compliance, the test equipment is controlled to perform a complementary discharge test on the battery according to the charge and discharge complementary parameter information.
[0097] Among them, if the processing terminal determines that the corresponding relationship corresponding to the charge and discharge complementary parameter information is consistent with the fully matched trigger data corresponding to the fully matched trigger information, it indicates that all batteries have batteries with which to exchange energy. Therefore, according to the corresponding relationship of the first test corresponding to the charge and discharge complementary parameter information, the test equipment is controlled to realize energy exchange between the corresponding batteries for the first test. After the first test is completed, the test equipment is controlled according to the corresponding relationship of the second test corresponding to the charge and discharge complementary parameter information to realize energy exchange between the corresponding batteries for the second test, thereby reducing energy waste during the test process.
[0098] Step 6012: If not, analyze the test parameter information and the charge-discharge complementary parameter information to determine the weak matching parameter information.
[0099] Among them, if the processing terminal determines that the corresponding relationship corresponding to the charge and discharge complementary parameter information is inconsistent with the fully matched trigger data corresponding to the fully matched trigger information, it indicates that there is a battery with which there is no energy exchange. Therefore, weak matching parameter information is determined according to the test parameter information and the charge and discharge complementary parameter information to provide data support for subsequent control test equipment to test the battery.
[0100] Weak matching parameter information refers to the test parameters of the battery that cannot exchange energy in the first test and the second test. The processing terminal compares the first test parameters and the second test parameter information corresponding to the test parameter information with the first test parameters and the second test parameters corresponding to the charge and discharge complementary parameter information, thereby selecting the inconsistent test parameters and obtaining the weak matching parameter information.
[0101] Step S602: Analyze the weak matching parameter information to determine supplementary parameter information.
[0102] Among them, the supplementary parameter information refers to the voltage and current parameters that need to be supplemented when testing the battery corresponding to the weak matching parameter information, and is determined by the processing terminal after analyzing the parameters corresponding to the weak matching parameter information. The specific analysis method is: according to the parameters of the first test and the parameters of the second test corresponding to the weak matching parameter information, an energy exchange match is performed again. This matching does not need to consider the complementarity between voltage and current. It only needs to match the charged and discharged batteries of the first test together, and then match the charged and discharged batteries of the second test together. Then, the supplementary parameters are obtained based on the voltage and current differences between the corresponding batteries, so as to minimize the actively increased energy and provide data support for the subsequent control test equipment to test the battery.
[0103] Step S603: controlling the test equipment to perform a mutual complementary discharge test on the battery according to the charge and discharge complementary parameter information, and controlling the test equipment to perform a complementary charge and discharge test on the battery according to the weak matching parameter information and the complementary parameter information.
[0104] Among them, after the processing terminal determines the weak matching parameter information, it controls the test equipment according to the complementary relationship of the first test corresponding to the charge and discharge complementary parameter information to realize the energy exchange between the corresponding batteries, and then controls the test equipment according to the complementary relationship of the second test corresponding to the charge and discharge complementary parameter information to realize the energy exchange between the corresponding batteries, thereby completing the test of the complementary batteries, and synchronously matches the batteries in the weak matching parameter information according to the corresponding relationship in the supplementary parameter information, and then controls the test equipment according to the supplementary parameters corresponding to the supplementary parameter information to make up for the voltage and current deficiencies between the weak matching batteries, thereby completing the test of the weak matching batteries.
[0105] Reference Figure 7 The steps of analyzing the test parameter information to determine the charge and discharge complementary parameter information include: Step S700: Analyze the test parameter information to determine first charge parameter information, first discharge parameter information, last discharge parameter information and last charge parameter information.
[0106] Among them, the charging parameter information first refers to the battery test parameters when the first test is charging, the discharging parameter information first refers to the battery test parameters when the first test is discharging, the discharging parameter information later refers to the battery test parameters when the second test is discharging, and the charging parameter information later refers to the battery test parameters when the second test is charging, which is obtained by the processing terminal identifying the first test parameters and the second test parameters in the test parameter information and classifying them.
[0107] Step S701: analyzing and matching the charge-first parameter information and the discharge-first parameter information to determine first standard matching parameter information.
[0108] Among them, the first standard matching parameter information refers to the correspondence between batteries that exchange energy with each other in the first test, which is determined by the processing terminal after analysis based on the charge first parameter information and the discharge first parameter information. The specific analysis method is: in the discharge first parameter information, battery No. 1 is first discharged at a voltage of 5 volts and a current of 1 amp; in the charge first parameter information, battery No. 2 is first charged at a voltage of 5 volts and a current of 1 amp. The correspondence between battery No. 1 and battery No. 2 is part of the first standard matching parameter information.
[0109] Step S702: Analyze and match the post-discharge parameter information and the post-charge parameter information to determine second standard matching parameter information.
[0110] Among them, the second standard matching parameter information refers to the correspondence between batteries that exchange energy with each other in the second test, which is determined by the processing terminal after analysis based on the post-discharge parameter information and the post-charge parameter information. The specific analysis method is: in the post-discharge parameter information, battery No. 3 is tested for discharge at a voltage of 5 volts and a current of 1 amp; in the post-charge parameter information, battery No. 4 is first tested for charging at a voltage of 5 volts and a current of 1 amp, then the correspondence between battery No. 3 and battery No. 4 is part of the second standard matching parameter information.
[0111] Step S703: Associating the first standard matching parameter information with the second standard matching parameter information to generate charging and discharging complementary parameter information.
[0112] Among them, the charge and discharge complementary parameter information in this step is consistent with the charge and discharge complementary parameter information in step S600. After the processing terminal determines the first standard matching parameter information and the second standard matching parameter information, the two are associated to obtain the correspondence between the batteries performing energy exchange in the first test and the batteries performing energy exchange in the second test, thereby obtaining the charge and discharge complementary parameter information.
