Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a control method, device, equipment and storage medium for a multi-module charging pile test system. Background Art

[0002] As the electric vehicle market continues to expand, the demand for charging facilities is also growing. In order to meet the needs of different users, a multi-module charging pile system came into being. This system uses advanced technology and design concepts, and has the characteristics of high efficiency, intelligence, safety, and reliability, becoming a star product in the field of electric vehicle charging.

[0003] The multi-module charging pile test system consists of multiple test modules, each of which is equipped with an independent control system. This design not only improves the test efficiency, but also allows for flexible expansion according to user needs. At the same time, the multi-module charging pile test system also adopts an intelligent management method, which can realize real-time monitoring and management of the test system through remote monitoring and control systems. In addition to the characteristics of high efficiency and intelligence, the multi-module charging pile test system also has the advantages of safety and reliability. Each test module is equipped with multiple safety protection measures, such as overcurrent protection, overvoltage protection, short circuit protection, etc. At the same time, the multi-module charging pile test system also uses high-quality materials and strict production processes to ensure the reliability and stability of the product.

[0004] In short, the multi-module charging pile test system is an efficient, intelligent, safe and reliable electric vehicle TV test facility. Its emergence will inject new impetus into the development of electric vehicles, and will also bring more convenient and environmentally friendly options for people's travel.

[0005] In the related art, when the multi-module charging pile test system issues current instructions, the target current value of each module, that is, the demand instruction, is divided by the number of modules in the channel, which leads to insufficient precision. For example, if the accuracy is 0.1A, if there are 24 modules, there will be a difference between the instruction and the actual value of 2.4A. To reduce this error, the instruction is issued by rounding, which can reduce the error by half, but there is still a difference of 1.2A. This will lead to the problem of reduced test accuracy. Summary of the invention

[0006] In order to precisely control each test module and ensure the accuracy and safety of the overall test system, the present application provides a multi-module charging pile test system control method, device, equipment and storage medium.

[0007] In the first aspect, the above-mentioned invention objective of the present application is achieved through the following technical solutions:

[0008] A multi-module charging pile test system control method, the multi-module charging pile test system control method comprising:

[0009] Sending unconfirmed simulated battery model information to a charging pile, and obtaining charging pile charging confirmation information based on the unconfirmed simulated battery model information;

[0010] In response to the charging confirmation information of the charging pile, controlling the preset test feedback module to receive current and obtain test charging feedback information;

[0011] According to the charging pile charging confirmation information and the test charging feedback information, obtaining the charging pile output current request value and the confirmed simulated battery model information;

[0012] According to the output current request value of the charging pile, control a preset response module and / or a standby module to receive the current and obtain test parameter information;

[0013] The confirmed simulated battery model information and the test parameter information are input into a preset battery model model to obtain a test result.

[0014] By adopting the above technical solution, when the charging gun of the charging pile is used to connect the test system, the test system will send a code including the simulated battery model and request information of the charging demand to the charging pile, and then receive the charging confirmation information sent back by the charging pile, and perform safety verification, for example, decoding the charging confirmation information of the charging pile to determine whether the confirmation code is correct. After the judgment is correct, the test module receives the output current of the charging pile. The test receiving charging is to further obtain the status and parameter information of the charging pile and perform further safety verification, so as to ensure the safety of the test system; the response module refers to the main test module that receives the current of the charging pile. The test system has multiple spare modules. When the receiving current value of each test module is When the division is uneven, the backup module is called to receive the current. When the receiving flow value of each test module is evenly divided, only the response module will be called to ensure that the attenuation speeds of the response module and the backup module are the same, avoiding inaccurate tests caused by different attenuation speeds. In the preset battery model model, the battery status, charging pile output current and charging current of the same vehicle model and the same battery model are collected, and the battery model model is trained through the records of multiple tests of the same vehicle model and the same battery model. In order to obtain more accurate test parameters such as the output current of the charging pile when simulating the same vehicle model and the same battery model for testing, precise control of each test module can be achieved to ensure the accuracy of the overall test system.

[0015] In a preferred example, the present application can be further configured as follows: the test feedback module, the response module and the standby module are obtained by:

[0016] Obtaining total module information, wherein the total module information includes information of several test module groups;

[0017] Each test module group is divided according to the test module group information and a preset test module group division rule to obtain the test feedback module, the response module and the standby module of each test module group.

[0018] By adopting the above technical solution, in the test system, each test module adopts exactly the same parameters and production time, and all test modules are grouped, each test module group corresponds to an input channel, and the preset test module group division rule refers to using the test module whose input port is closest to the input channel as the test feedback module, and using the test module whose input port is farthest from the input channel as the spare module according to the position of each test module in each test module group. In this way, the speed of performing test feedback testing is improved, and the number of times the spare module is called is the least. The input port of the spare module is farthest from the input channel, which reduces the electromagnetic interference generated when the current passes through, thereby ensuring the service life of the spare module.

[0019] In a preferred example, the present application can be further configured as follows: in response to the charging confirmation information of the charging pile, controlling the preset test feedback module to receive current and obtaining the test charging feedback information specifically includes:

[0020] In response to the charging pile charging confirmation information, the unconfirmed simulated battery model information is input into the battery model model to obtain the corresponding test receiving current rule;

[0021] Based on the test receiving current rule, the test feedback module is controlled to receive the current of the charging pile, and the feedback charging current, the feedback charging pile output current, the feedback capacity and the feedback charging capacity are obtained;

[0022] The test charging feedback information includes the feedback charging current, the feedback charging pile output current, the feedback capacity and the feedback charging capacity.

[0023] By adopting the above technical solution, in response to the charging confirmation information of the charging pile, when it is necessary to determine whether the charging pile correctly identifies the battery model, the unconfirmed simulated battery model information is input into the battery model model, and the test receiving current rule corresponding to the battery model is obtained from the battery model model. The test receiving current rule includes the charging pile output parameters suitable for the battery type obtained from the manufacturer of the battery type. Based on the output parameters, it is easy to judge the output state of the charging pile, thereby improving the safety and accuracy of testing the charging pile.

[0024] In a preferred example, the present application may be further configured as follows: obtaining the charging pile output current request value and the confirmed simulated battery model information according to the charging pile charging confirmation information and the test charging feedback information, specifically including:

[0025] Obtaining the normal range of the charging pile output from the test receiving current rule;

[0026] Compare the feedback charging current, the feedback charging pile output current, the feedback capacity and the feedback charging capacity with the normal range of the charging pile output to obtain a comparison result;

[0027] If the comparison result indicates that the charging pile output is abnormal, an abnormal information is sent to a monitoring management terminal connected to the test system;

[0028] If the comparison result indicates that the charging pile output is normal, the unconfirmed simulated battery model information is used as the confirmed simulated battery model information, and the charging pile output current request value is obtained according to the charging pile charging confirmation information.

[0029] By adopting the above technical scheme, the normal range of the charging pile output is obtained from the test receiving current rule, and the feedback charging current, feedback charging pile output current, feedback battery capacity and feedback charging capacity in the test charging feedback information are compared with the corresponding range values ​​in the normal range of the charging pile output. Only when it is judged that the feedback charging current, feedback charging pile output current, feedback battery capacity and feedback charging capacity are all within the corresponding range values ​​in the normal range of the charging pile output, can it be judged that the charging pile correctly identifies the battery model and the output status is normal. After judging that the output status of the charging pile is normal, the unconfirmed simulated battery model information is used as the confirmed simulated battery model information indicating that the verification has passed, and according to the charging pile charging confirmation information sent by the charging pile, the charging request of the charging pile is obtained. In this way, the safety of the charging pile test system is further improved, and the accuracy of the obtained charging pile output current request value is guaranteed.

[0030] In a preferred example, the present application can be further configured as follows: according to the output current request value of the charging pile, controlling the preset response module and / or standby module to receive the current and obtaining the test parameter information specifically includes:

[0031] According to the charging pile output current request value and the preset test module group receiving planning rule, the test module group receiving planning information of each test module group is obtained;

[0032] If the test module groups of each test module group receive the same planning information, control the response module of each test module group to receive current and obtain test parameter information;

[0033] If the charging module group of each test module group receives inconsistent planning information, the backup module and the response module of each test module group are controlled to receive current and obtain test parameter information according to the test module group output planning information of each test module group.

[0034] By adopting the above technical solution, the preset test module group receiving planning rule is to judge whether the receiving current of each response module can be evenly distributed according to the receiving accuracy of each parameter module of the test system. If the receiving current of each response module can be evenly distributed, only the response module needs to be used for receiving. If it is judged that the receiving current of each response module cannot be evenly distributed, it is necessary to call the spare module. By increasing the number of test modules, the receiving current of each response module and spare module can be evenly distributed or the difference between the actual test current value and the output current value of the charging pile can be minimized. In this way, the balanced and precise control of each response module and spare module is achieved, thereby achieving the effect of reducing the difference between the actual test current value and the output current value of the charging pile.

[0035] In a preferred example, the present application can be further configured as follows: the test parameter information includes the charging pile output state information, the charging pile output current and the charging current; the confirmed simulated battery model information and the test parameter information are input into a preset battery model model to obtain the test result, specifically including:

[0036] Input the confirmed simulated battery model information and the test current parameter information into a preset battery model model to obtain a charging current relationship, a charging pile output state relationship, and a charging pile output current relationship;

[0037] Obtaining a current output current difference according to the charging pile output state information, the charging pile output current and the charging current, as well as the charging current relationship, the charging pile output state relationship and the output current relationship;

[0038] A test result is obtained based on the current output current difference, and the charging current relationship equation, the battery state relationship equation and the output current relationship equation are updated based on the current output current difference.

[0039] By adopting the above technical solution, in the actual charging test process, the output current of the charging pile will be dynamically adjusted according to the state and requirements of the test system, that is, as the voltage of the test system increases, the output current of the charging pile will gradually decrease to maintain the stability of the voltage of the test system. Therefore, a charging current relationship, a charging pile output state relationship and an output current relationship are preset in the battery model model. Each relationship represents the dynamic change relationship between a parameter and the other two parameters, that is, the related change of another parameter when the two parameters change. In addition, the purpose of setting three different relationship formulas is to balance the relationship between the various parameters to improve the accuracy of each relationship formula, and to be able to train the relationship formula in the battery model model based on the records of each charging of the same model of battery, so as to obtain a more accurate correlation between the changes in various parameters of each model of battery, thereby achieving precise control of each test module and ensuring the accuracy of the overall test system.

[0066] The following is combined with Figure 1-8 This application is described in further detail.

[0067] A multi-module charging pile test system refers to setting up multiple test modules, each of which can be tested and independently controlled, as well as monitoring the charging pile status and the test system status, and the multi-module charging pile test system is also provided with a communication module for communicating with the charging pile.

[0068] In one embodiment, if Figure 1 As shown, the present application discloses a multi-module charging pile test system control method, which specifically includes the following steps:

[0069] S10: Sending unconfirmed simulated battery model information to the charging pile, and obtaining charging confirmation information of the charging pile based on the unconfirmed simulated battery model information.

[0070] In this embodiment, a plurality of test modules are provided in the test system, and the test modules in the test system are divided into a test feedback module for performing test feedback charging to determine whether the charging pile correctly identifies the battery model, a response module for receiving the charging pile current in the largest number, and a standby module for receiving the charging pile current when the current is unevenly distributed. Unconfirmed simulated battery model information refers to information used to indicate that the charging pile has not been verified to have correctly identified the simulated battery model. Charging pile charging confirmation information refers to information sent by the charging pile to confirm the charging request.

[0071] Specifically, when the test system is connected to the charging pile, the test system simulates the battery of the electric vehicle, and after detecting the charging pile, the test system sends information for requesting charging and simulated battery model information to the charging pile. At this time, it is not verified that the charging pile correctly identifies the simulated battery model information. Therefore, the simulated battery model information is the unconfirmed simulated battery model information. When the charging pile receives the information requesting charging, it will send information including confirmation of charging and the current value of confirming charging to the test system, that is, the charging pile charging confirmation information.

[0072] S20: In response to the charging confirmation information of the charging pile, controlling a preset test feedback module to receive current and obtain test charging feedback information.

[0073] In this embodiment, the test charging feedback information refers to the preliminary detected test system status information and charging pile status information.

[0074] Specifically, in response to the charging confirmation information of the charging pile, the divided test feedback module is controlled to receive the output current of the charging pile, so as to judge whether the test system and the charging pile are in a normal current receiving mode. When the test feedback receiving current is performed, the current value output by the charging pile is small. When the test feedback receiving current is performed, the test system's parameters such as the simulated battery capacity and the simulated charging capacity, as well as the output current of the charging pile and other parameters are detected, that is, the test charging feedback information.

[0075] S30: According to the charging pile charging confirmation information and the test charging feedback information, the charging pile output current request value and the confirmed simulated battery model information are obtained.

[0076] In this embodiment, the charging pile output current request value refers to the current value requested to be output by the charging pile. The confirmed simulated battery model information refers to the information used to represent the battery model that has been verified and judged to be correctly identified and simulated by the charging pile.

[0077] Specifically, according to the test charging feedback information, that is, parameters such as the battery capacity and charging capacity of the battery, and parameters such as the output current of the charging pile, it is determined whether the simulated battery capacity and simulated charging capacity of the test system are normal under the current output current parameters of the charging pile, that is, the normal battery capacity and charging capacity of the battery of this model are obtained from the preset battery model model under the current output current of the charging pile. The variation range; if the parameters represented by the test charging feedback information are all within the corresponding variation range obtained from the preset battery model model, it is determined that the current state of the charging pile is normal, and the model of the battery is used as the information for representing the battery model that has been verified to be correctly identified by the charging pile, that is, the simulated battery model information has been confirmed, and the current value requested to be output by the charging pile is obtained from the charging confirmation information of the charging pile, that is, the output current request value of the charging pile.

[0078] S40: According to the output current request value of the charging pile, control the preset response module and / or standby module to receive the current and obtain the test parameter information.

[0079] In this embodiment, the test parameter information refers to parameter information of the tested charging pile and the test system.

[0080] Specifically, according to the current value represented by the output current request value of the charging pile, determine whether the output current request value of the charging pile can be evenly distributed to each response module in the test system, that is, whether the overall receiving current of the test system is the same as the current value represented by the output current request value of the charging pile when the receiving current of each response module of the test system is consistent. If it is determined that they are the same, the current value that needs to be allocated to each response module will be calculated and corresponding instructions will be issued to control the response module receiving current. If it is determined that the receiving current of each response module of the test system is consistent and the overall receiving current of the test system is different from the current value represented by the output current request value of the charging pile, then according to the number of spare modules, it is calculated from low to high whether the receiving current of each response module and the spare module can be consistent and the overall receiving current of the test system can be consistent after each additional spare module is added. The current value represented by the output current request value of the charging pile is the same. When it is judged to be the same, the current value allocated to each response module and the called standby module is calculated and the corresponding instruction is issued; when adding all the standby modules still cannot achieve the consistency of the receiving current of each response module and the standby module and the same as the current value represented by the output current request value of the charging pile, the number of standby modules added is calculated so that the receiving current of each response module and the standby module is consistent after adding the standby modules, and the difference between the overall receiving current of the test system and the output current request value of the charging pile is minimized, and the corresponding instruction is issued; in addition, when charging, the parameters representing the output of the charging pile, such as the current value output by the charging pile, and the parameters representing the overall state of the test system, such as the current value received by the test system, are detected, that is, the test parameter information.

[0081] Furthermore, each time it is determined that the output current request value of the charging pile has changed, it is determined whether the backup module needs to be called based on the above method.

[0082] S50: Input the confirmed simulated battery model information and test parameter information into a preset battery model to obtain a test result.

[0083] In this embodiment, the test result refers to a result used to indicate whether the current value tested by the test system is accurate.

[0084] Specifically, after obtaining the test parameters, the test parameters include parameter information such as the temperature, receiving voltage and simulated battery capacity of the test system that represent the overall state of the test system, and parameter information such as the charging pile output current and charging current that represent the output of the charging pile. When it is determined through the battery status information that the required current value of the battery has changed, for example, when the battery voltage changes, the confirmed simulated battery model information and the test parameter information are input into a preset battery model model. In the battery model model, a relationship expression corresponding to the confirmed simulated battery model information that represents the correlation between the output parameters of the charging pile and the state information of the test system is obtained. According to the relationship expression, it is determined whether the current output parameters of the charging pile correspond to the state information of the test system, and whether the current output parameters of the charging pile are within the corresponding variation range threshold, so as to obtain a result indicating whether the current value tested by the test system is accurate, that is, the test result.

[0085] In one embodiment, if Figure 2 As shown, the test feedback module, response module and backup module are obtained by:

[0086] S01: Obtain total module information, which includes information of several test module groups.

[0087] In this embodiment, the total module information refers to the number of all test modules of the test system and parameter information of each test module. The test module group information refers to the number of grouped test modules.

[0088] Specifically, after the test system is installed, the number of all test modules of the test system and the parameter information of each test module, that is, the total module information, are first obtained. In the present embodiment, the electrical parameters of all test modules of the test system are the same, and the total module information also includes the number of grouped test modules, that is, the test module group information. The test module group information indicates that the test system includes several test module groups, each test module group includes several test modules, and each test module group corresponds to an input channel.

[0089] S02: Divide each test module group according to the test module group information and the preset test module group division rule to obtain a test feedback module, a response module and a spare module of each test module group.

[0090] Specifically, the preset test module group division rule means that according to the position of each test module in each test module group, the test module whose input port is closest to the input channel is used as the test feedback module, and the test module whose input port is farthest from the input channel is used as the backup module. Therefore, the test module whose input port is closest to the input channel in each test module group is used as the test feedback module, and the test module whose input port is farthest from the input channel are used as the backup module, and the remaining test modules are used as response modules.

[0091] Furthermore, since the input current when using the test feedback module for test feedback charging is relatively small, only one test module is needed. In order to facilitate the division of the test feedback module and not waste test module resources, a separate test feedback module that is not included in the test module group is designed during the design of the test system. When actually dividing each test module group, only the response module and the spare module need to be divided.

[0092] In one embodiment, if Figure 3 As shown, in step S20, in response to the charging confirmation information of the charging pile, the preset test feedback module is controlled to receive the current and obtain the test charging feedback information, which specifically includes:

[0093] S21: In response to the charging confirmation information of the charging pile, input the unconfirmed simulated battery model information into the battery model model to obtain the corresponding test receiving current rule.

[0094] In this embodiment, the test receiving current rule refers to rule information for controlling the receiving current of the test system when performing test feedback charging.

[0095] Specifically, in response to the charging pile charging confirmation information sent by the charging pile, the information indicating the battery model identified by the charging pile is read from the charging pile charging confirmation information sent by the charging pile, and the unconfirmed simulated battery model information is input into the battery model model, and the test receiving current rule corresponding to the battery model represented by the unconfirmed simulated battery model information is obtained from the battery model model. The test receiving current rule refers to the rule information for controlling the receiving current when the test system performs test feedback charging. In this embodiment, the test receiving current rule includes the output current of the charging pile suitable for this model obtained from the manufacturer of the battery of this model, and the battery model model includes the test receiving current rule for batteries circulating on the market.

[0096] S22: Based on the test receiving current rule, the test feedback module is controlled to receive the current of the charging pile, and the feedback charging current, the feedback charging pile output current, the feedback battery capacity and the feedback charging capacity are obtained.

[0097] In this embodiment, the feedback charging current refers to the charging current detected when the test feedback charging is performed. The feedback charging pile output current refers to the charging pile output current detected when the test feedback charging is performed. The feedback battery capacity refers to the battery capacity detected when the test feedback charging is performed. The feedback charging capacity refers to the charging capacity detected when the test feedback charging is performed.

[0098] Specifically, based on the charging pile output current suitable for the current model of battery in the test receiving current rule, the test feedback module is controlled to receive the current of the charging pile, and the charging current, charging pile output current, battery capacity and charging capacity during the test feedback charging are detected, that is, the charging current, the charging pile output current, the battery capacity and the charging capacity are fed back.

[0099] S23: The test charging feedback information includes the feedback charging current, the feedback charging pile output current, the feedback battery capacity and the feedback charging capacity.

[0100] Specifically, the obtained test charging feedback information includes feedback charging current, feedback charging pile output current, feedback battery capacity and feedback charging capacity.

[0101] In one embodiment, if Figure 4 As shown, in step S30, according to the charging confirmation information of the charging pile and the test charging feedback information, the charging pile output current request value and the confirmed simulated battery model information are obtained, specifically including:

[0102] S31: Obtain the normal range of the charging pile output from the test receiving current rule.

[0103] In this embodiment, the normal range of the charging pile output refers to the range value information used to determine whether the output current of the current charging pile is normal.

[0104] Specifically, the normal range of the charging pile output is obtained from the obtained test receiving current rule. The normal range of the charging pile output refers to the range value information used to determine whether the current battery is normal, that is, after the charging pile charges the test system, the range value information is used to determine whether the current output current of the charging pile is within the range.

[0105] S32: Compare the fed-back charging current, the fed-back charging pile output current, the fed-back battery capacity and the fed-back charging capacity with the normal range of the charging pile output to obtain a comparison result.

[0106] In this embodiment, the comparison result refers to the comparison result between the normal range of the output current of the charging pile and the corresponding parameter.

[0107] Specifically, the normal range of the charging pile output includes the range values ​​of the corresponding charging current, charging pile output current, battery capacity and charging capacity. Therefore, the feedback charging current, feedback charging pile output current, feedback battery capacity and feedback charging capacity are respectively compared with the corresponding range values ​​in the normal range of the battery status to obtain the comparison results.

[0108] S33: If the comparison result indicates that the output of the charging pile is abnormal, an abnormal information is sent to a monitoring management terminal connected to the test system.

[0109] In this embodiment, the abnormal information refers to information used to prompt that an abnormality exists in the charging pile currently connected to the test system.

[0110] Specifically, if the comparison result indicates that the output of the charging pile, that is, the feedback charging current, the feedback charging pile output current, the feedback battery capacity and the feedback charging capacity, there is one or more values ​​that are not within the corresponding range values ​​in the normal range of the charging pile output, then it is judged that the current output state of the charging pile is abnormal, and charging may cause damage to the charging pile and the test system. Therefore, information is sent to the monitoring and management end that is communicated with the test system to prompt that there is an abnormality in the charging pile currently connected to the test system, that is, abnormal information.

[0111] S34: If the comparison result indicates that the charging pile output is normal, the unconfirmed simulated battery model information is used as the confirmed simulated battery model information, and the charging pile output current request value is obtained according to the charging pile charging confirmation information.

[0112] Specifically, if the comparison result indicates that the battery status is normal, that is, the feedback charging current, the feedback charging pile output current, the feedback battery capacity and the feedback charging capacity are all within the corresponding range values ​​in the normal range of the charging pile output, then it is judged that the charging pile output is normal and the current charging pile has passed the safety verification. The unconfirmed simulated battery model information is used as the confirmed simulated battery model information, and the charging pile output current request value representing the current value requested by the charging pile to charge is extracted from the charging confirmation information of the charging pile.

[0113] In one embodiment, if Figure 5 As shown, in step S40, according to the output current request value of the charging pile, the preset response module and / or standby module is controlled to receive the current and obtain the test parameter information, which specifically includes:

[0114] S41: According to the output current request value of the charging pile and the preset test module group receiving planning rule, the test module group receiving planning information of each test module group is obtained.

[0115] In this embodiment, the test module group receiving planning information refers to the receiving current value of the test module group.

[0116] Specifically, the preset test module group receiving planning rule refers to a rule that calculates the current value represented by the charging pile output current request value according to the receiving accuracy of each test module of the test system and distributes it evenly to each test module group and evenly to each test module in each test module group. In this embodiment, the preset test module group receiving planning rule is a rule that calculates the current value represented by the charging pile output current request value and distributes it evenly to each test module group and evenly to each response module in each test module group. Therefore, according to the current value represented by the charging pile output current request value and the preset test module group receiving planning rule, the receiving current value evenly distributed to each test module group is obtained, that is, the test module group receiving planning information.

[0117] Furthermore, if the current value represented by the charging pile output current request value cannot be evenly distributed to each test module group, then based on the output accuracy of the test module group, under the condition that the current value represented by the remaining charging pile output current request value is the smallest, calculate and record the first current value of the current value represented by the charging pile output current request value evenly distributed to each test module group and evenly distributed to each response module in each test module group, and the second current value of the remaining minimum current value evenly distributed to each test module group and evenly distributed to each standby module in each test module group. At this time, the test module group receives the planning information including the first current value and the second current value.

[0118] S42: If the test module groups of each test module group receive the same planning information, control the response module of each test module group to receive current and obtain the test parameter information.

[0119] Specifically, if the test module groups of each test module group receive consistent planning information, that is, the current value represented by the charging pile output current request value can be evenly distributed to each test module group and evenly distributed to each response module in each test module group, then the response modules in each test module group are controlled to receive current after evenly distributing the current value represented by the planning information received by the test module group, and detect the current value output by the charging pile and other parameters representing the output of the charging pile and the current value received by the test system and other parameters representing the overall state of the test system, that is, test parameter information.

[0120] S43: If the charging module groups of each test module group receive inconsistent planning information, then according to the test module group output planning information of each test module group, control the standby module and the response module of each test module group to receive current and obtain test parameter information.

[0121] Specifically, if the planning information received by each charging module group is inconsistent, that is, the current value represented by the charging pile output current request value cannot be evenly distributed to each test module group and evenly distributed to each test module in each test module group, the charging module group receives the planning information including the first current value and the second current value. Therefore, according to the first current value and the second current value, the response module and the standby module of each test module group are respectively controlled to receive the current, and the parameters representing the output of the charging pile, such as the current value output by the charging pile, and the parameters representing the overall state of the test system, such as the current value received by the test system, are detected, that is, the test parameter information.

[0122] In one embodiment, if Figure 6 As shown, in step S50, the test parameter information includes the charging pile output state information, the charging pile output current and the charging current, and the confirmed simulated battery model information and the test parameter information are input into the preset battery model model to obtain the test results, which specifically include:

[0123] S51: Input the confirmed simulated battery model information and the test current parameter information into a preset battery model model to obtain a charging current relationship, a charging pile output state relationship, and a charging pile output current relationship.

[0124] In this embodiment, the charging current relationship refers to the relationship between the charging current and the charging pile output state information and the charging pile output current. The charging pile output state relationship refers to the relationship between the charging pile output state information and the charging current and the charging pile output current. The charging pile output current relationship refers to the relationship between the charging pile output current and the charging current and the charging pile output state information.

[0125] Specifically, the confirmed simulated battery model information and test current parameter information are input into a preset battery model model, and a charging current relationship formula, a charging pile output state relationship formula and an output current relationship formula are obtained from the battery model model, wherein the charging current relationship formula refers to a relationship formula for the correlation between the charging current and the charging pile output state information and the charging pile output current, the charging pile output state relationship formula refers to a relationship formula for the correlation between the charging pile output state information and the charging current and the charging pile output current, and the charging pile output current relationship formula refers to a relationship formula for the correlation between the charging pile output current and the charging current and the charging pile output state information.

[0126] S52: Obtain the current output current difference according to the charging pile output state information, the charging pile output current and the charging current, as well as the charging current relationship, the charging pile output state relationship and the output current relationship.

[0127] In this embodiment, the current output current difference refers to the difference between the charging pile output state information, the charging pile output current and the charging current obtained through the relationship and the corresponding relationship.

[0128] Specifically, the relevant relationship refers to a relationship that refers to the correlation between one parameter and another two parameters. For example, the charging current relationship is used to determine the corresponding change information of the charging current when the charging pile output status information and / or the charging pile output current changes. Therefore, the corresponding charging pile output status information, charging pile output current and charging current are input into the charging pile output status relationship, the charging current relationship and the output current relationship to obtain the charging pile output status information, the charging pile output current and the charging current and the difference between the relationship, that is, the current output current difference. For example, after the charging pile output status information and the charging pile output current are input into the charging current relationship, a changed charging current will be obtained. The changed charging current is compared with the current charging current to obtain the current output current difference of the corresponding charging current.

[0129] S53: Obtaining a test result based on the current output current difference, and updating the charging current relationship equation, the battery state relationship equation, and the output current relationship equation based on the current output current difference.

[0130] Specifically, the corresponding current output current difference is compared with the corresponding preset difference threshold value. The preset difference threshold value refers to the output difference of the charging pile that can be received by the self-set value. For example, it can be set to 0.1A, 0.2A or 0.3A. If the current output current difference does not exceed the corresponding difference threshold value, the test result of normal charging pile output is obtained. If the current output current difference exceeds the corresponding difference threshold value, the test result of abnormal charging pile output is obtained. Furthermore, the corresponding relationship in the battery model model is trained according to each current output current difference.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
