[0109] Based on the solutions shown in any one or more of the above embodiments, please refer to Figure 6 , Figure 6 is a flow chart of a vehicle charging detection method according to an embodiment of the present application, the method comprises the above Figure 1 The detection device 100 in the vehicle battery tester shown is executed, and the above step 520 can be implemented as step 520a and step 520b; the above method also includes: step 530 and step 540.

[0110] Step 520a: Receive the remote control instruction sent by the control device through the communication module, and send the remote control instruction to the signal module.

[0111] Among them, the above-mentioned control device is a device that controls and monitors the detection process through remote communication technology, and the control device includes but is not limited to smart phones, tablet computers, computers (desktop or laptop computers), dedicated controllers and cloud-based platforms.

[0122] Step 530: Send the detection result of the vehicle's power battery to the communication module through the signal module.

[0123] Step 540: Send the detection result of the vehicle's power battery to the control device through the communication module.

[0124] In an embodiment of the present application, the communication module is capable of receiving instructions from a remote control device, so that the operator can perform detection and control at a location far away from the vehicle, thereby reducing the dependence of the vehicle charging detection method on on-site environmental conditions and improving the convenience of the vehicle charging detection method; the presence of the communication module allows the detection results to be transmitted to the control device in real time, providing instant feedback to technicians, and by sending the detection results to the control device, remote monitoring and data analysis can be achieved, thereby improving the efficiency of vehicle charging detection.

[0125] Based on the scheme shown in any one or more of the above-mentioned embodiments, the above-mentioned step 520 can be implemented as follows: through the signal processing module, control the signal transceiver module to send a detection signal to the vehicle; through the signal transceiver module, receive the feedback signal and send it to the signal processing module; through the signal processing module, perform detection on the vehicle's power battery according to the feedback signal.

[0126] In the embodiment of the present application, the signal transceiver module is responsible for communicating directly with the vehicle, sending detection signals and receiving feedback signals, making the communication interaction process more efficient and reliable. By refining the functional division of the signal module, efficient signal transmission and precise data processing are achieved, thereby enhancing the accuracy and response speed of vehicle charging detection.

[0127] Based on the scheme shown in any one or more of the above-mentioned embodiments, the detection device in the above-mentioned vehicle battery tester sends a first detection instruction to the signal transceiver module through the signal processing module; the first detection instruction is an instruction for instructing to detect the power battery of the vehicle; the first detection instruction is detected by the signal transceiver module; when the signal transceiver module detects the first detection instruction, a detection signal is sent to the vehicle through the signal transceiver module according to the first detection instruction.

[0128] In an embodiment of the present application, the vehicle charging detector sends a specific first detection instruction to the signal transceiver module through the signal processing module, ensuring that the signal transceiver module will start the detection process only after receiving clear instructions, effectively avoiding unnecessary misoperation and ensuring that each detection is based on accurate needs. When the signal transceiver module successfully detects the first detection instruction, it sends a corresponding detection signal to the vehicle according to the first detection instruction, which can significantly reduce the impact of external interference on the detection results and improve the effect of vehicle charging detection.

[0129] Based on the solutions shown in any one or more of the above embodiments, in some embodiments, the vehicle battery tester determines whether the first detection instruction is sent normally through a signal processing module.

[0130] In the embodiment of the present application, the above scheme determines the sending status of the first detection instruction through the signal processing module, which can immediately discover and locate problems that may occur during the instruction transmission process, avoid detection interruption or repeated operations due to failure to send instructions, and improve the overall detection efficiency. By verifying the correct sending of the first detection instruction, the credibility of the detection result can be enhanced. When the first detection instruction is successfully delivered to the target device, the feedback signal obtained is valid, which is crucial for accurately evaluating the status of the power battery. The above scheme optimizes the detection process and further improves the accuracy and efficiency of the detection.

[0131] Based on the schemes shown in any one or more of the above-mentioned embodiments, in some embodiments, when the first detection instruction is sent normally, the vehicle battery tester continues to send the second detection instruction through the signal processing module; the second detection instruction is the next new detection instruction after the first detection instruction; when the first detection instruction is not sent normally, a fault reminder is issued; the fault reminder is used to indicate that a fault has occurred in the vehicle battery tester.

[0132] In an embodiment of the present application, after confirming that the first detection instruction has been successfully sent, the vehicle battery tester automatically sends the second detection instruction through the signal processing module, which not only improves the detection efficiency, but also ensures the continuity and integrity of the detection process, and avoids delays or errors that may be caused by human intervention. When it is detected that the first detection instruction is sent abnormally, a fault reminder is immediately triggered, which can quickly prompt the operator to pay attention and take timely measures, effectively preventing detection interruptions or data loss caused by failure to timely discover communication failures, and ensuring the smooth progress of the detection work. Through the fault reminder mechanism, the problem can be quickly located, providing a clear direction for subsequent fault diagnosis and maintenance, reducing troubleshooting time, and reducing maintenance costs. The above scheme optimizes the detection process and improves work efficiency.

[0138] The remote communication module 703 is used to send signals in conjunction with the supporting APP to achieve remote control.

[0139] After the charging gun is inserted into the vehicle's charging port, the signal processing module 702 controls the issuance of signal instructions, which are sent by the signal sending module 701 to simulate normal slow charging conditions of the charging gun, thereby facilitating slow charging detection of the entire vehicle. The signal processing module 702 can be manually controlled or remotely debugged via the remote communication module 703.
