[0002] With the increasing popularity of new energy vehicles, the number of charging piles in the market also increases. However, due to the different brands and models of charging piles, the charging quality is uneven. During the development stage of new energy vehicles, it is necessary to complete the adaptation of vehicles to most charging piles in the market, so it is necessary to perform a charging test between the vehicle and the charging pile to determine whether the vehicle and the charging pile are adapted.
[0003] In related technologies, a standard test case is obtained to obtain a fault test case according to a test case with a fault in the test result of the standard test case, and to update target information in the standard test case according to a preset compilation method to obtain a horizontal expansion test case, thereby realizing the adaptability test of the vehicle and the charging pile. Although this method can test under the standard and under the standard expansion, it cannot completely test all charging characteristics of the actual charging of the charging pile, and there is limitation in testing according to the standard.
[0004] In another related technology, when testing the adaptability of the vehicle and the charging pile, the log data during the actual charging between the vehicle and the charging pile is obtained, and then the required message data is extracted and written to the corresponding position of the battery management system for analysis to obtain charging adaptability test data. This method requires the actual charging process of the vehicle and the charging pile, and the steps are complicated and complex. Therefore, the current test efficiency and effect of the adaptability test of the vehicle and the charging pile are poor. SUMMARY
[0005] The present application provides a charging test method and device of a power battery, a vehicle and an electronic device, and the purpose of the present application is to at least solve the technical problem of low test efficiency and poor effect in the related art when testing the adaptability of the vehicle and the charging pile.
[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:
[0007] According to a first aspect provided by the present application, a charging test method for a power battery is provided, the charging test method for the power battery comprising: obtaining charging data of a charging device charging a first power battery, the charging data comprising: charging control data of the charging device, and first charging operation data of the first power battery, where the first power battery is a power battery that has been put into use; generating a test case based on the charging control data; performing a charging test on a second power battery based on the test case to obtain second charging operation data of the second power battery, where the second power battery is a power battery that has not been put into use; and determining charging compatibility between the second power battery and the charging device based on the first charging operation data and the second charging operation data.
[0008] According to the above technical means, the present application generates a test case based on the charging control data obtained by obtaining the charging data of the charging device charging the first power battery that has been put into use. Then, based on the test case, a charging test is performed on the second power battery that has not been put into use to obtain the second charging operation data of the second power battery. In this way, through the charging data of the existing power battery by the actual charging device, a test case corresponding to the existing charging device can be generated. Then, based on the test case, the existing charging device can be simulated on the host computer to perform a charging test on the second power battery that has not been put into use. And based on the obtained second charging operation data, combined with the first charging operation data corresponding to the first power battery that has been put into use, the charging compatibility between the second power battery and the charging device can be determined. In this way, the charging test of the second power battery that has not been put into use can be performed without finding the actual charging device, thereby efficiently and accurately determining the compatibility between the power battery and the charging device.
[0009] In a possible implementation, the charging control data includes control data of at least one control component in the charging device, where the control component includes: a pilot circuit, an electronic lock, an auxiliary power supply, a controller, a power supply circuit, and a charger.

Therefore, based on the control data of these control components, when generating test cases, the actual operating status of the charging device can be fully simulated, so that when performing a charging test on the second power battery that has not been put into use based on the test case, more accurate test results can be obtained.
[0011] In a possible implementation, the charging control data comprises data of at least one charging phase in the charging process, and the charging phase comprises a physical connection phase of the charging device and the first power battery, a handshake start phase, an insulation detection phase, a pre-charging phase, a formal charging phase, and an end charging phase.

In this way, by dividing the charging control data into the data of multiple phases, the actual charging process can be simulated completely when the test case is generated. Therefore, when the second power battery that is not put into use is tested based on the test case, more accurate test results can be obtained.

In this way, by obtaining the charging data between different charging devices and different first power batteries in multiple scenarios, test cases in multiple scenarios can be generated, so that when the second power battery that is not put into use is tested, more comprehensive and accurate test results can be obtained based on the test cases in multiple scenarios.
[0015] In a possible implementation, the test case is generated based on the charging control data, including: for one set of charging data in the multiple sets of charging data, one test case is generated based on the charging control data in the one set of charging data.
[0016] According to the above technical means, after obtaining the charging data between different charging devices and different first power batteries in multiple scenarios, the application can generate multiple test cases according to the charging control data in each set of charging data obtained from the multiple sets of charging data, and obtain the test cases in multiple scenarios. Therefore, when charging test is performed on the second power battery that is not put into use, more comprehensive and accurate test results can be obtained based on the test cases in multiple scenarios.

[0018] According to the above technical means, the application can first generate a charging model file based on the charging control data in a set of charging data. Then, the charging model file is imported into a pre-created test script, and the test case corresponding to the set of charging data is generated. In this way, the test case can be quickly and accurately constructed through the test script and the generated model file.
[0019] In a possible implementation, the above importing the charging model file into the pre-created test script to generate the test case corresponding to the set of charging data includes: configuring a file path of the charging model file in a bus development and test tool on the host computer; and controlling the host computer to perform a test case generation task, so that the host computer imports the charging model file into the test script based on the file path to generate the test case corresponding to the set of charging data.
[0020] According to the above technical means, the application can configure the file path of the charging model file in the bus development and test tool on the host computer. In this way, when the host computer is controlled to perform the test case generation task, the host computer can obtain the charging model file based on the file path and import the charging model file into the test script to generate the test case corresponding to the set of charging data. In this way, the charging model file can be accurately obtained by configuring the file path of the charging model file, and the test case can be efficiently generated.

[0052] The charging test method of the power battery provided by the embodiments of the present application can be applied to a charging test system of the power battery. As shown in Figure 1 The charging test system of the power battery includes a charging device 11, a first power battery 12, a host computer 13 and a second power battery 14.
[0053] The charging device 11 is a charging device (such as a charging pile) that has been put into use, the first power battery 12 is a power battery (such as a power battery used on a vehicle) that has been put into use, the host computer 13 is an electronic device, and the second power battery 14 is a power battery that has not been put into use (such as a power battery in the development stage, not used on a vehicle in use).
[0054] In a possible implementation, the charging device 11 can be connected with the first power battery 12, so as to charge the first power battery 12 by the charging device 11.

[0059] The host computer 13 can also determine charging adaptability between the second power battery 14 and the charging device 11 based on the first charging operation data and the second charging operation data.
[0060] For ease of understanding, the charging test method of the power battery provided in the present application is specifically introduced below in combination with the accompanying drawings. As shown in FIG. 1, the charging test method of the power battery includes S201-S204: Figure 2
[0061] S201, acquiring charging data of a charging device charging a first power battery.
[0062] The charging data includes charging control data of the charging device and first charging operation data of the first power battery, and the first power battery is a power battery that has been put into use.
[0063] In the embodiments of the present application, a charging test simulation system (i.e., an upper computer and a test case) is provided to replace the scheme of automatically charging a vehicle (including a power battery to be tested) to be tested by a charging device (e.g., a direct-current charging pile). The present application sorts out a charging process, determines collected data, collects data, processes data, forms a data list of charging characteristics of a charging device, and then develops a test case by using an excel and a test case writing software (vTESTstudio), executes the test case by using a bus development and test tool (CANoe), compares and analyzes test results with actually collected data of the charging device, revises the test case, and verifies again.
[0064] In a possible implementation, the acquisition process of charging data is specifically described by taking a direct-current charging pile as an example. The charging data, also referred to as charging characteristics, can include data such as physical parameter changes in a control guide circuit of the direct-current charging pile, a communication message format, and a communication message content. According to a charging process in GBT 27930-2015 "Communication protocol between electric vehicle non-vehicle conductive charger and battery management system protocol", parameters involved in the entire direct-current charging process are sorted out. Whether the data is stable can be determined according to single-pile single-charging data, whether the data is the same can be determined according to single-pile multiple-charging data, and whether the charging characteristics are the same can be determined according to multiple-vehicle single-pile charging data.
[0065] In a possible implementation, a data list can be formed after the charging data of the charging pile is acquired. The charging data of the direct-current charging pile is analyzed by using a controller area network (CAN) communication collection tool, an electric vehicle direct-current charging and discharging data collection analyzer, and a vehicle-mounted bus analysis tool (CANalyzer), so as to complete extraction of charging parameters of the direct-current charging pile.
[0066] In the embodiments of the present application, the charging process can specifically include: a process that a vehicle is physically connected with a charging pile, a process that the charging pile is powered on with low voltage assistance, a process that the vehicle and the charging pile start to charge handshake, a process that charging parameters are configured, a charging phase, and a process that charging is completed.
[0067] In some embodiments, the charging control data includes control data of at least one control component in the charging device, and the control component includes: a guide circuit, an electronic lock, an auxiliary power supply, a controller, a power supply loop, and a charger.
[0068] Correspondingly, the charging control data includes: guide circuit control data, electronic lock control data, auxiliary power supply control data, insulation detection control data, power supply loop control data, and charger message control data.
[0069] In an embodiment of the present application, the present application can obtain control data of at least one control component in the guiding circuit, electronic lock, auxiliary power supply, controller, power supply circuit, and charger of the charging device when the charging device charges the first power battery that has been put into use. Therefore, based on the control data of these control components, when generating a test case, the actual operating state of the charging device can be fully simulated, so that when performing a charging test on the second power battery that has not been put into use based on the test case, a more accurate test result can be obtained.
[0070] In some embodiments, the charging control data includes data of at least one charging stage in the charging process, and the charging stages include: the physical connection stage between the charging device and the first power battery, the handshake startup stage, the insulation detection stage, the pre-charging stage, the formal charging stage and the charging end stage.
[0071] Specifically, at least one charging phase in the charging process may include: physical connection phase, low-voltage auxiliary power-up phase, vehicle-pile handshake communication phase, parameter configuration phase, charging phase, and end phase. After sorting out the specific phases of the charging process, data collection and confirmation can be performed for each phase.
[0072] For example, Figure 3 The figure shows the schematic diagram of the DC charging control and guidance circuit after the vehicle is connected to the DC charging station. The DC charging station includes: an AC / DC converter 301, a transformer 302, a DC / DC converter 303, a diode 304, a voltage measuring device 305, a fuse 306, a bleeder circuit 307, a K1 switch 308, a K2 switch 309, an insulation monitoring device (IMD) 310, an auxiliary power supply 311, a controller 312, an R1 resistor 313, a K3 switch 314, and a K4 switch 315. The DC charging station also includes a device ground terminal, CC1. One end of the R1 resistor 313 is connected to the power supply U1, and the other end is connected to detection point 1. The charging interface between the vehicle and the DC charging station includes: an R2 resistor 316, an R3 resistor 317, an R4 resistor 318, and an S switch 319. The charging interface also includes CC2. The vehicle (power battery) section includes: K5 switch 320, K6 switch 321, power battery 322, vehicle controller 323, and R5 resistor 324. The vehicle (power battery) section also includes a vehicle body ground terminal. One end of R5 resistor 324 is connected to power supply U2, and the other end is detection point 2.
[0073] In a possible implementation, the physical connection stage needs to collect: the opening and closing state of the electronic lock, the state of the S switch 319, the CC1 switch state, the CC2 switch state, the CC1 voltage value, the opening and closing state of the K3 switch 314 and the K4 switch 315. The low-voltage auxiliary power-on stage needs to collect: the voltage of the auxiliary power supply 311, the opening and closing state of the K3 switch 314 and the K4 switch 315. The vehicle pile handshake communication stage needs to collect: the format and content of the charge handshake (CHM) message, the format and content of the charger recognition message (CRM), the opening and closing state of the K1 switch 308 and the K2 switch 309, whether the BMS handshake (BHM) message is received, the running state and voltage value of the insulation detection circuit, the state of the bleeder circuit 307, and whether the battery management system (BMS) BMS and vehicle recognition message (BRM) is received. The parameter configuration stage needs to collect: whether the power battery charging parameter message (BCP) is received, the sending format and content of the charger time synchronization information message (CTS), the sending format and content of the charger maximum output capability message (CML), and whether the BMS charging readiness message (BRO) is received. The charging stage needs to collect: the sending format and content of the charger readiness status message (CRO) message, the outside voltage value of the K1 switch 308 and the K2 switch 309, the relay state of the K1 switch 308 and the K2 switch 309, the output voltage of the charging pile, the output current of the charging pile, whether the battery charging request message (BCL) is received, whether the battery charging status message (BCS) is received, and the sending format and content of the charger charging status message (CCS).In the ending stage, the following information needs to be collected: the output state of the charging pile, the format and content of the charger stopping charging message (CST), whether the BMS stopping charging message (BST) is received, whether the BMS statistical data message (BSD) is received, the format and content of the charger statistical data message (CSD), whether the output current of the charging pile is less than 5A, the relay state of the K1 switch 308 and the K2 switch 309, the voltage value outside the K1 switch 308 and the K2 switch 309, the state of the electronic lock, and the like.
[0074] In a possible implementation, each of the physical connection stage, the handshake starting stage, the insulation detection stage, the pre-charging stage, the formal charging stage, and the ending stage can be further subdivided into multiple steps, and the physical parameters, the guide circuit switch, the charging message format and content, the charging pile voltage and current output, and the like involved in each step are controlled.
[0075] In a possible implementation, the charging data involved in each stage can be compiled in an excel programming manner, and each case (each charging) needs to be named as a different file name, so as to obtain the charging data of the direct current charging pile corresponding to each charging. In the embodiment of the present application, the data of at least one charging stage, including the physical connection stage, the handshake starting stage, the insulation detection stage, the pre-charging stage, the formal charging stage, and the ending stage, of the charging device and the first power battery during the charging process can be obtained. In this way, by dividing the charging control data into the data of multiple stages, the actual charging process can be completely simulated when the test case is generated. Therefore, when the second power battery that is not put into use is charged and tested based on the test case, more accurate test results can be obtained.
[0076] In some embodiments, as shown in FIG. 4, the S201 can specifically include S401-S403. Figure 4
[0077] S401, a plurality of sets of charging data when the charging device charges the first power battery multiple times are obtained.
[0078] Each charging corresponds to a set of charging data.
[0079] In a possible implementation, when the charging data of the first power battery charged by the charging device is acquired, a USB CANFD 200U is used to connect with the vehicle diagnosis port, ZCANpro software is opened, the baud rate of the vehicle CAN and the DC CAN is set, and the data is saved. At the same time, the electric vehicle DC charging and discharging data acquisition analyzer is connected to the charging interface between the vehicle and the charging gun to acquire and save the charging data.

[0114] Specifically, run the CANoe software and run the compiled test case in the Test menu, saving the messages in the Trace. After the test is complete, replay the data in the Trace and Graphics files and compare it with the data collected by the DC charging station to determine whether the charging characteristics run by the CANoe software (i.e., the second charging operation data of the second power battery) are consistent with the charging characteristics collected by the actual DC charging station, and then adjust the test case.
[0115] That is, in the embodiment of this application, the model file path is configured in the CANoe software for subsequent execution cases, and a test script is created in the Vtest software. The model file environment is configured in the CANoe software and a case is generated for automatic execution of the backup case.
