Abstract

The invention relates to the technical field of charging pile fault detection, in particular to a detection system and method for judging faults by detecting the temperature of an air inlet and an air outlet of a charging pile, and the system comprises a charging pile body, an air inlet, an air outlet, fan equipment, a dust cover, a temperature sensor, a charging pile component and a detection assembly.

[0001] The present invention relates to the technical field of charging pile fault detection, and particularly to a detection system and method for judging faults by detecting the temperatures of the air inlet and outlet of a charging pile. Background Art

[0002] With the rapid development of new energy vehicles in China, new energy charging piles have gradually been installed in various public places. In order to improve the charging pile efficiency, fast charging of two major types of 400V and 800V has been installed in many parking lots. With the increase of the working voltage and charging speed, a large amount of heat is generated inside the charging pile during operation. Therefore, a fan device is installed inside the charging pile for cooling the inside of the charging pile. However, when the fan device operates for a long time, by sucking external air into the inside of the charging pile, the external air usually contains dust. After a large amount of dust accumulates, it will affect the operation of the fan device, resulting in a decrease in the heat dissipation effect. A dust-proof cover is provided inside the charging pile, and the dust-proof cover can filter dust to avoid the influence of dust on the operation of the fan device and ensure the normal heat dissipation of the charging pile; after long-term use, the fan device may fail, which will further affect the heat dissipation effect. Therefore, the safety detection of the fan is particularly important.

The higher the incoming temperature, the higher the discharged temperature should be, and the lower the incoming temperature, the lower the discharged temperature should be; when the temperature sensor 6 detects that the discharged temperature exceeds the preset value, it indicates that the dust-proof cover 5 may be blocked or the filtering effect has decreased, resulting in a smaller heat dissipation wind speed and thus an increase in the discharged temperature; or it indicates that the fan device 4 has a fault resulting in an increase in the discharged temperature; at this time, the humidity sensor 8 performs humidity detection.
