Description

Technical Field

[0002] The electric vehicle CDU (Conversion & Distribution Unit, on-board charger) wake-up and sleep test is one of the most important test items in the electric vehicle CDU test. If the CDU wake-up and sleep function fails, the CDU will not be able to start. In the CDU design, it is necessary to test whether the CDU wake-up and sleep test complies with national standards and design requirements to meet production and use requirements. If only a single CDU wake-up and sleep test is performed, it is easy to cause the probability of occasional success. If this problem extends to the production end, it will cause irreparable losses. Therefore, the CDU wake-up and sleep test needs to be repeated multiple times to reduce the randomness of the test and increase the accuracy of the test results.

[0003] At present, the CDU wake-up and sleep test of electric vehicles is mainly carried out through an integrated test tool box, which uses a large number of hard switches for connection control. During the test, it is necessary to rely on manual repeated switch control, which is easy to cause accidental switch operation and damage the device. At the same time, long-term repeated switching of the switch reduces the service life of the switch, and consumes a lot of manpower costs. In addition, manual testing will cause operational errors and other problems, affecting the test results. Summary of the invention

[0015] Monitoring whether the on-board charger enters the pre-sleep state or the sleep state;

[0016] If so, the first wake-up source is started for the second time to switch the on-board charger to the wake-up state until the wake-up time is reached.

[0017] After obtaining the first test result of the first wake-up source, the testing method further includes:

[0018] When the first test result is a wake-up failure, the test is terminated, and the current wake-up source of the failure of the on-board charger pre-sleep wake-up test is recorded.

[0027] Obtain a selection instruction for a pre-sleep wake-up sleep test function in a display interface, and generate a pre-sleep test instruction;

[0028] Controlling the on-board charger to enter a pre-sleep state according to the pre-sleep test instruction;

[0029] Among them, the display interface also includes one or more of the overall wake-up and sleep-down test function, the CC wake-up and sleep-down test function, the CP wake-up and sleep-down test function, and the KL15 wake-up and sleep-down test function.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] The CDU wake-up and sleep-down test system described in the automated CDU wake-up and sleep-down test system provided in the present application is a wake-up and sleep-down test system for assisting in testing the CDU. The CDU described in the present application is an electric vehicle power supply, including an electric vehicle charger and an electric vehicle DCDC converter. The technical effects to be achieved by the present application are as follows:

[0048] 1. The automated testing system can test a test case repeatedly, reduce the randomness of the test passing, detect occasional failures, and make the test results more real and reliable.

[0049] 2. The wake-up and sleep test of CDU consumes a lot of human resources and time costs. This automated testing system can reduce time, manpower and material costs based on the automated testing of the system, thereby achieving the function of reducing costs and increasing efficiency.

[0050] 3. The wake-up test from the pre-sleep to sleep stage in the CDU wake-up and sleep test is difficult to implement manually, takes a long time, and the test results are not ideal.

[0051] 4. Use the electronic display screen to view and operate the control panel to simplify the test process and test difficulty.

[0052] The electric vehicle CDU wake-up and sleep-down test of the present application is a wake-up and sleep-down test on the on-board power supply of the electric vehicle, including but not limited to: CC wake-up and sleep-down test, CP wake-up and sleep-down test, KL15 wake-up and sleep-down test, pre-sleep wake-up and sleep-down test, etc.

[0053] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a flow chart of an embodiment of a method for testing a vehicle charger provided by the present application, Figure 2 This is the overall block diagram of the automated CDU wake-up and sleep test system provided by this application. Figure 3 It is a schematic diagram of the overall process of the overall wake-up and sleep test solution provided in this application.

[0054] The vehicle charger test method of the present application is applied to a test device, wherein the test device of the present application can be a server, a terminal device, or a system in which a server and a terminal device cooperate with each other. Accordingly, the various parts included in the test device, such as various units, subunits, modules, and submodules, can all be set in the server, can all be set in the terminal device, or can be set in the server and the terminal device respectively.

[0055] Furthermore, the above-mentioned server can be hardware or software. When the server is hardware, it can be implemented as a distributed server cluster consisting of multiple servers, or it can be implemented as a single server. When the server is software, it can be implemented as multiple software or software modules, such as software or software modules used to provide distributed servers, or it can be implemented as a single software or software module, which is not specifically limited here.

[0056] like Figure 2 As shown, the automated CDU wake-up and sleep-down test system provided in the present application is mainly composed of four parts: a wake-up source signal control circuit, a CAN (Controller Area Network) transceiver, an MCU (Micro Control Unit) controller and a display.

[0057] The automated CDU wake-up and sleep-down test system is connected to the CDU externally through a low-voltage wiring harness. When the CDU needs to be woken up and sleep-down tested, just click the corresponding soft switch on the large screen. The MCU controller receives the corresponding signal, controls the wake-up source signal circuit, and generates the corresponding wake-up source. These wake-up sources are transmitted to the on-board charger CDU through the low-voltage wiring harness to wake up the CDU. After being woken up, the CDU sends a message to the outside through CAN communication. The CAN transceiver receives the corresponding data information and passes it to the MCU. The MCU determines whether the corresponding test is successful by judging the received message and transmits the result to the display screen.

[0058] Please continue to read Figure 4 , Figure 4 It is a schematic diagram of the display screen interface of the automated CDU wake-up and sleep-test system provided in this application.

[0059] like Figure 4 As shown, the display screen interface of the automated CDU wake-up and sleep test system provided by the present application mainly consists of two parts: a soft switch and a display frame. The display screen has three test control switches: test start, test end, and test pause, which can control the start, end, and pause of the test respectively. The soft switch also has five test module buttons: overall wake-up and sleep test, CC wake-up and sleep test, CP wake-up and sleep test, KL15 wake-up and sleep test, and pre-sleep wake-up and sleep test.

[0060] When the user clicks one of the test module buttons and clicks to start the test, the MCU will perform corresponding operations according to the received instructions and transmit the test results to the display screen. The display box shows the ongoing test items, the current test log and the statistical test results. The tester can analyze and judge whether the current CDU wake-up and sleep test meets the national standards and design requirements by viewing the log and test results.

[0061] The test method of the present application sends a command to the MCU by clicking the switch on the display screen. After receiving the command, the MCU controls the on and off of the CDU wake-up source by controlling the relay. The embedded CAN transceiver receives the wake-up source of the CDU and transmits it to the MCU controller. The MCU controller analyzes the received CAN data message, determines whether the current state of the CDU is correct, and transmits the result to the display through I2C communication for the tester to view.

[0062] The entire test process is fully automated, and manual operation is only required when selecting the test type and viewing the test results, which reduces labor costs and time costs, and achieves the goal of reducing costs and increasing efficiency. Secondly, the test items are repeated many times, which reduces the randomness of test success, improves test accuracy, and may detect occasional wake-up failures, improving user experience. Next, for the pre-sleep stage wake-up test, the system timer is used for cyclic testing, and the sleep test is woken up every 0.2S, which solves the current difficulties in implementing pre-sleep wake-up tests and the low test rate. Finally, using the switch on the display to issue instructions is not easy to damage the switch or accidentally hit the switch, and it is easy to operate and implement.

[0063] like Figure 1 As shown, the specific steps are as follows:

[0064] Step S11: in response to the on-board charger entering the pre-sleep state, turning on the first wake-up source to perform a pre-sleep wake-up test on the on-board charger.

[0065] In the embodiments of this application, please refer to Figure 5 , Figure 5 It is a flowchart of the pre-sleep wake-up test solution provided in this application.

[0066] Specifically, the test device uses the first wake-up source to perform a pre-sleep wake-up test on the on-board charger, such as Figure 5 As shown, the first wake-up source may be a CP wake-up source.

[0067] In other specific embodiments, the first wake-up source may also be any one of a CC wake-up source, a CP wake-up source, and a KL15 wake-up source.

[0068] Step S12: Obtain a first test result of the first wake-up source.

[0069] In the embodiment of the present application, taking the CP wake-up source as the first wake-up source as an example, the test device uses the CP wake-up source to wake up the CDU and detects whether the CDU is awakened. If the CDU wakes up successfully, it monitors in real time whether the CDU enters the pre-sleep state. When the CDU enters the pre-sleep state, it starts timing, starting from 3s, and continues to perform the pre-sleep wake-up test with the CP wake-up source by adding 0.2s each time.

[0070] Until the number of successful awakenings by the CP wake-up source reaches a preset threshold, the test device determines that the test result of the CP wake-up source is a successful test. When the CP wake-up source fails to wake up successfully in any pre-sleep wake-up test, the test device determines that the test result of the CP wake-up source is a test failure, and judges that the CP wake-up source fails the pre-sleep wake-up test, ends the single cycle, and records the current wake-up source that failed the pre-sleep wake-up test of the on-board charger.

[0071] It should be noted that when the test device uses the preset wake-up source to wake up the on-board charger, it is necessary to detect whether the on-board charger successfully enters the pre-sleep state within the preset time. If not, it means that the preset wake-up source fails to wake up, that is, the test result of the preset wake-up source is wake-up failure.

[0072] Step S13: When the first test result is that the wake-up is successful, the second wake-up source is turned on to perform a pre-sleep wake-up test on the on-board charger.

[0073] In the embodiment of the present application, when the test result of the first wake-up source is determined to be a successful wake-up according to step S12, the test device continues to turn on the second wake-up source to perform a pre-sleep wake-up test on the on-board charger.

[0074] Similarly, the second wakeup source may also be any one of the CC wakeup source, the CP wakeup source and the KL15 wakeup source.

[0075] In particular, when the first wake-up source and the second wake-up source in the embodiment of the present application are both CC wake-up sources, the CC wake-up source resistance of the first wake-up source may be different from the CC wake-up source resistance of the second wake-up source.

[0076] Step S14: Obtain a second test result of the second wake-up source.

[0077] In an embodiment of the present application, the testing device turns on the Sth wake-up source and performs a wake-up sleep test. If there is no wake-up failure within 6S, it is determined and displayed that the CDU pre-sleep wake-up test of the Sth wake-up source is successful. Otherwise, it is determined that the pre-sleep wake-up test of the current wake-up source has failed and the single cycle is ended.

[0078] Step S15: When the second test result is that the wake-up is successful and the second wake-up source is the final wake-up source, confirm that the on-board charger has passed the pre-sleep wake-up test.

[0079] In an embodiment of the present application, the testing device determines whether the current wake-up source is the final wake-up source, wherein the final wake-up source is a pre-set wake-up source.

[0080] If the current wake-up source is the final wake-up source, the test device confirms that the on-board charger has passed the pre-sleep wake-up test. If the current wake-up source is not the final wake-up source, the test device turns on the next wake-up source and re-enters the pre-sleep cycle test until all wake-up source cycles are completed, then the current cycle is exited and the pre-sleep wake-up test is recorded as successful.

[0081] The test device of this application can be Figure 4 The pre-sleep wake-up test function button on the display screen interface shown starts the test method of the embodiment of the present application.

[0082] Further, Figure 4 Please refer to the detailed implementation process of CC wake-up and sleep test function, CP wake-up and sleep test function, and KL15 wake-up and sleep test function on the display interface. Figures 6 to 8 .in, Figure 6 This is a flowchart of the CC wake-up and sleep test solution provided by this application. Figure 7 This is a flowchart of the CP wake-up and sleep test solution provided in this application. Figure 8 It is a flowchart of the KL15 wake-up and sleep test solution provided in this application.

[0083] Above Figure 6-Figure 8 These are all flow charts of a single cycle of the test module. Figure 6 Taking the CC wake-up and sleep test shown in the figure as an example, the wake-up and sleep test process is as follows:

[0084] First, the system waits for one minute for the CDU to enter sleep mode, and determines whether the current waiting times exceed 5 times. If so, it determines and displays that the CDU sleep mode has failed, and exits the current cycle. If it does not exceed 5 times, it performs CAN communication detection to determine whether the CDU is in sleep mode. If not, it continues to wait for one minute, and the number of cycles increases by 1. After entering sleep mode, the MCU controls the wake-up source signal control circuit to turn on the corresponding CC wake-up source. The system sets three different CC wake-up sources, namely 1.5KΩ, 680Ω, and 220Ω CC wake-up sources.

[0085] Then the MCU detects the CAN communication to determine whether the CDU is awakened. If the CDU fails to be awakened, it will display CC wake-up failure and exit the current loop. If the CDU wakes up successfully, the MCU analyzes whether the current CC resistance and CC connection status match the current wake-up source (the resistance is the corresponding ohm, and the CC connection status is connected). If the match fails, it will display CC wake-up failure and exit the current loop. If the match is successful, it will record and display CC wake-up success. Wait for one minute and perform CAN communication detection again to determine whether the CDU is dormant. If it is not dormant, it will determine and display CC dormancy failure and exit the current loop. If the dormancy is successful, determine which wake-up source the current wake-up source is, and repeatedly start the next wake-up source to wake up. After the wake-up source is cycled three times, the current loop ends.

[0086] The automated CDU wake-up and sleep test system of this application is Figure 6-Figure 8 Each test module is set up with 100 cycles of testing, and the number of cycles can be modified according to your own ideas. Figure 7 and Figure 8 The wake-up sleep test process is similar to Figure 6 The cycle flow of the wake-up and sleep test process shown is similar and will not be repeated here. The difference is that the CP signal wake-up source only sets one wake-up source, and when inputting the wake-up source, it is not necessary to input the wake-up source cyclically.

[0087] The test method of the present application can automatically test the wake-up and sleep tests of the CDU, greatly reducing the manpower cost and time cost, and can achieve the purpose of reducing costs and increasing efficiency.

[0088] The test method of the present application tests the CDU wake-up sleep test from the pre-sleep to sleep stage, solves the problem that the current CDU pre-sleep wake-up test is difficult, and increases the accuracy of the test results.

[0089] The test method of the present application achieves the ability to repeatedly perform CDU wake-up and sleep tests, with a single test cycle of one hundred times, which reduces the randomness of the test results and can detect some occasional faults, thereby increasing the reliability of the test results.
