Problems solved by technology

[0004] Traditional DC charging piles are generally "fast charging", and some older electric vehicles are prone to short circuits or fires during charging due to aging internal circuits. At this time, if there is no one around, the charging cannot be cut off in time The power supply is likely to cause damage to the DC charging pile;

Abstract

The invention relates to a direct-current charging system with built-in infrared hot spot detection. The direct-current charging system comprises a direct-current charging pile body, a control module and a power-off mechanism; the control module is arranged in the direct current charging pile body, an infrared temperature measurement sensor is further fixedly installed in the direct current charging pile body, and the infrared temperature measurement sensor is electrically connected with the control module; a power-off mechanism is also fixedly mounted on the direct-current charging pile body; the power-off mechanism comprises a third shell, a conductive cable, a fixing plate and a sliding plate. The third shell is fixedly connected to the outer end of the direct-current charging pile body. When an electric automobile is charged, if spontaneous combustion occurs, after the infrared temperature measurement sensor senses abnormal temperature, a signal is transmitted to the control module, and the control module powers off the first electromagnet and the second electromagnet, so that the charging circuit of the charging gun is disconnected, short circuit is prevented, and the direct current charging pile body is protected.

Description

technical field [0001] The invention relates to the technical field of charging equipment, in particular to a DC charging system with built-in infrared hotspot detection. Background technique [0002] The function of the charging pile is similar to the refueling machine in the gas station. It can be fixed on the ground or wall, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential area parking lots or charging stations. Charge all models of electric vehicles. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle; [0003] DC charging pile is a DC electric vehicle charging station, commonly known as "fast charging". It is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the power battery of off-vehicle electric vehicles; [0004...
