[0002] With the popularization of new energy vehicles, especially electric vehicles, electric vehicles have become the travel choice of more and more families and enterprises. However, although electric vehicles have significant advantages in environmental protection and energy conservation, they still face the problem of insufficient power, which is particularly prominent during long-distance travel or long-time driving. Especially when a charging pile cannot be found in time, insufficient power may cause the vehicle to stop on the road, bringing great inconvenience to the vehicle owner.

[0003] Currently, the emergency treatment solutions for insufficient power of electric vehicles mainly include using road rescue services or relying on tow trucks to send the vehicle to a charging station. These methods not only take time, but also may require high costs and additional transportation arrangements. In addition, some electric vehicle manufacturers provide emergency charging services, but the availability and coverage of such services are limited and it is difficult to provide a quick solution in all cases.

[0004] Therefore, we propose a portable comprehensive detector for vehicle charging, discharging and high-voltage equipment to facilitate the solution of the problems raised above. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the accompanying drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions facing or away from the geometric center of a specific component. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present invention.

[0026] Please refer to Figure 1-2 As shown, the present invention provides a portable vehicle charging and power-taking, high-voltage equipment comprehensive detector, including an equipment box 1. A plurality of partitions 16 are arranged in the equipment box 1, and the partitions 16 divide the inner cavity of the equipment box 1 into multiple installation spaces for hierarchical installation of each device. A direct charging unit, a power-taking and charging unit, and a power transmission unit for connecting the direct charging unit, the power-taking and charging unit, and the vehicle to be repaired are arranged in the installation space of the equipment box 1;

[0027] The power transmission unit includes a charging module 2, a DC contactor 3, and a charging gun 4. The input end and the output end of the DC contactor 3 are electrically connected to the output end of the charging module 2 and the input end of the charging gun 4 respectively;

[0028] The direct charging unit includes a circuit breaker 5 and an AC contactor 6. The output end of the circuit breaker 5 is electrically connected to the input end of the AC contactor 6, and the output end of the AC contactor 6 is electrically connected to the input end of the charging module 2;

[0029] The power-taking and charging unit includes a power-taking gun 7 and a power-taking contactor 8. The output end of the power-taking gun 7 is electrically connected to the input end of the power-taking contactor 8, and the output end of the power-taking contactor 8 is electrically connected to the input end of the charging module 2.

[0030] During direct charging, the mains power passes through the circuit breaker 5 and then enters the charging module 2 through the AC contactor 6. The charging module 2 transforms it into direct current through voltage transformation and rectification (the conversion process is prior art, such as first rectifying through a rectifier, then filtering through a filter, and then stabilizing the voltage through a voltage regulator, etc.). Subsequently, it passes through the DC contactor 3 and the charging gun 4 and enters the vehicle to be repaired, realizing the power supply to the vehicle to be repaired;

[0031] During power taking and charging, insert the power taking gun 7 into the emergency repair vehicle and the charging gun 4 into the vehicle to be repaired. The high-voltage power supply of the emergency repair vehicle enters the charging module 2 through the power taking gun 7 and the power taking contactor 8, and then passes through the DC contactor 3 and the charging gun 4 and enters the vehicle to be repaired, realizing the power supply to the vehicle to be repaired.

[0032] The equipment box 1 is also provided with a control unit, a display screen 12, a 12V switching power supply 13, a 24V switching power supply 14, and a DC-DC converter 15. The control unit includes an operation panel 11, a power taking controller 10, and a control main board 9. The 12V switching power supply 13 and the 24V switching power supply 14 are respectively used to supply power to the control main board 9 and the display screen 12 during direct charging. The output end of the operation panel 11 is electrically connected to the input ends of the power taking controller 10 and the control main board 9 to issue instructions to them. The output end of the power taking controller 10 is electrically connected to the input end of the power taking contactor 8, and the output end of the control main board 9 is electrically connected to the input end of the charging module 2. The display screen 12 is connected to the control main board 9 for displaying charging data.

The power taking controller 10 sends a message to the emergency repair vehicle, and the emergency repair vehicle outputs high-voltage direct current to provide electrical energy for the charging module 2 through the power taking gun 7. The charging module 2 outputs direct current through the charging gun 4 to charge the vehicle with a dead battery. The display screen 12 and the operation panel 11 are both arranged outside the equipment box 1 for the convenience of staff operation.

[0033] At the same time, the equipment has a detection function. By operating the operation panel 11 and the control main board 9, the current and voltage of the charging module 2 are raised and lowered to meet the current and voltage required for the detection firmware on the vehicle to be repaired. For example, when detecting the electric defrosting function, make the charging module 2 provide 300V voltage, and then check whether the electric defrosting firmware is working to conduct maintenance and troubleshooting on it.

[0034] As a preferred technical solution of the present utility model: A plurality of ventilation holes 17 are provided on the side wall of the equipment box 1 to facilitate the ventilation and heat dissipation of the internal components of the equipment box 1.
