[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0019] like Figure 1 、 Figure 2 and Figure 4 As shown, a dual-modular charging detection device includes a chassis 11, an alarm light 1 is fixedly connected to the top of the chassis 11, an electronic display screen 2 is fixedly provided at the upper front end of the chassis 11, a pause button 4 is fixedly provided in the middle of the front of the chassis 11, a power button 3 and a power off button 5 are fixedly provided on both sides of the pause button 4, a test mode switch 6 and an AC / DC integrated charging base 10 are fixedly provided at the lower front end of the chassis 11, a charging mode switch 7 is fixedly provided at the bottom of the test mode switch 6, a DC charging gun 8 and an AC charging gun 9 are provided on the AC / DC integrated charging base 10, ventilation inspection doors 12 are fixedly installed on both sides of the chassis 11, and a charging gun judgment module 17, a protection module 16, a communication module 15, a control module 14 and an electronic display screen monitoring module 13 are provided in the chassis 11.

[0020] The control module 14 includes a voltage detection control unit, a current detection control unit, a temperature detection control unit, a power detection control unit, a duration detection control unit, a test detection control unit, a charging detection control unit, a heat dissipation detection control unit and a central controller. The voltage detection control unit, the current detection control unit, the temperature detection control unit, the power detection control unit, the duration detection control unit, the test detection control unit, the charging detection control unit and the heat dissipation detection control unit are all electrically connected to the central controller.

[0021] After each frame of information from the electronic display screen monitoring module 13 is sent to the control module 14 at a cycle time of 500 ms, the control module 14 first determines which function it is (voltage, current, temperature, power, duration, test, or charging function) according to the preset detection and control function strategy. Taking the voltage detection control unit as an example, after determining that it is a voltage function, the voltage detection control unit presets a voltage range. If the actual voltage value is within the preset voltage range, the judgment result is "normal". The communication module 15 transmits the information to the electronic display screen monitoring module 13 at a cycle time of 500 ms, and the actual voltage value is displayed in real time on the electronic display screen 2. If the actual voltage value is not within the preset voltage range, the judgment result is "abnormal". The communication module 15 transmits the information to the electronic display screen monitoring module 13, the alarm light 1, and the protection module 16 at a cycle time of 500 ms. "Voltage abnormality" is displayed in real time on the electronic display screen 2. The alarm light 1 prompts maintenance, and the voltage protection system in the protection module 16 supports power supply maintenance with low voltage. The same applies to other detection control units.

[0022] The communication module 15 is electrically connected to the central controller.

[0023] The protection module 16 includes a voltage protection unit, a current protection unit, a heat dissipation protection unit, a high-temperature protection unit, a full-charge protection unit, a timeout protection unit, a test protection unit, a charging protection unit, a parameter fault diagnosis protection unit, and a protection processor. The voltage protection unit, the current protection unit, the heat dissipation protection unit, the high-temperature protection unit, the full-charge protection unit, the timeout protection unit, the test protection unit, the charging protection unit, and the parameter fault diagnosis protection unit are all electrically connected to the protection processor, and the protection processor is electrically connected to the central controller. Taking the voltage protection unit as an example, if the actual voltage value in the voltage detection control unit in the control module 14 is not within the preset voltage range, the control module 14 sends a command to the communication module 15 to transmit the information to the protection module 16. The voltage protection unit in the protection module 16 activates protection and supports power supply maintenance in a low-voltage state. The same applies to other protection units.

[0024] The charging gun judgment module 17 includes a fast charging judgment unit, a slow charging judgment unit, and a charging gun judgment controller. The fast charging judgment unit and the slow charging judgment unit are both electrically connected to the charging gun judgment controller, and the charging gun judgment controller is electrically connected to the central controller. Charging gun judgment process: If the operator inserts the DC charging gun 8 into the fast charging socket of the electric vehicle, the charging gun judgment module 17 determines that it is a fast charging function based on the preset fast and slow charging function strategies. Then, the communication module 15 reports the DC fast charging to the control module 14. The control module 14 sends an instruction to the communication module 15 to transmit the information "DC fast charging" to the electronic display screen monitoring module 13. The electronic display screen 2 displays "DC charging gun", which is considered to be the end of the charging gun judgment. The same applies to AC charging guns. The judgment time is 500 ms. If no result is determined within 500 ms, the communication module 15 will report "no result" to the control module 14, which is regarded as "charging gun judgment abnormality". The control module 14 sends an instruction to the communication module 15 to transmit the information "charging gun judgment abnormality" to the electronic display screen monitoring module 13 and the alarm light 1, stop the charging gun judgment, and the alarm light 1 lights up to prompt maintenance.

[0025] The electronic display screen monitoring module 13 includes an electronic display screen controller, an electronic monitoring unit, an electronic database unit, and a 5G communication unit. The electronic display screen controller is electrically connected to the electronic display screen 2, and the electronic display screen controller, electronic monitoring unit, electronic database unit, and 5G communication unit are all electrically connected to the central controller. By setting up the electronic display screen monitoring module 13, the parameters and data of the device during operation can be monitored and monitored. The monitored and monitored information can be displayed on the electronic display screen 2, which plays a role in monitoring and real-time data collection and recording for the device. This module reports the preset monitoring and monitoring function strategy and each frame of monitoring and monitoring information to the control module 14 via the communication module 15 at a cycle time of 500 ms. The control module 14 makes a judgment and sends the judgment result to this module, which then displays the judgment result of the control module 14 in real time on the electronic display screen 2.

[0026] like Figure 3 As shown, the operation steps of the dual modular charging detection device are as follows:

[0027] 1. Under the premise that there is power input at the starting end of the device, the operator manually turns on the power button 3, and then the device automatically turns on the electronic display screen 2. The electronic display screen 2 lights up, and the device startup is completed. According to the function to be implemented at the moment, manually turn on the corresponding functional module. If you want to use the test function, manually turn on the test mode switch 6 to test the electric vehicle for fast and slow charging; if you want to use the charging function, manually turn on the charging mode switch 7 to charge the electric vehicle for fast and slow charging;

[0028] 2. After selecting the function module, manually remove the DC charging gun 8 or AC charging gun 9 from the AC / DC integrated charging station 10 and then insert it into the new energy vehicle. If the DC charging gun 8 is detected, perform a fast charge test or fast charge; if the AC charging gun 9 is detected, perform a slow charge test or slow charge. During this process, only one gun is allowed to be inserted; mixing two guns is not allowed.

[0029] 3. After using any of the above two functional modules, if you want to restart the functional module or switch to another functional module, you need to manually press the pause button 4 to pause the device, and then manually start the corresponding functional module according to the previous idea. If you do not need to use the functional module anymore, the operator can manually press the shutdown button 5, and the device will automatically turn off the electronic display screen 2. The electronic display screen 2 is turned off and the device is powered off.

[0030] 4. During the entire operation, if the electronic display screen 2 shows a test abnormality or a charging abnormality, the alarm light 1 will light up, indicating that maintenance is required; if the electronic display screen 2 shows a test completion or a charging completion, the alarm light 1 will light up, indicating that the test is completed.

[0031] The module circuit process is as follows:

[0032] A. Circuit 1 (test circuit): Power on power input - test mode switch 6 - charging gun judgment module 17, communication module 15, electronic display screen monitoring module 13, control module 14, protection module 16, these five modules start working.
