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 DC charging system with built-in infrared hotspot detection, comprising a DC charging pile body; a control module and a power-off mechanism; a control module is arranged in the DC charging pile body, and an infrared temperature measuring device is fixedly installed in the DC charging pile body The sensor, the infrared temperature sensor and the control module are electrically connected; a power-off mechanism is fixedly installed on the body of the DC charging pile; the power-off mechanism includes a third shell, a conductive cable, a fixing plate and a slide plate, and the third shell is fixedly connected At the outer end of the DC charging pile body; when the electric vehicle is charging, if spontaneous combustion occurs, when the infrared temperature sensor senses an abnormal temperature, the signal is sent to the control module, and the control module controls the first electromagnet and the second electromagnet. The power is cut off, so the charging circuit of the charging gun is disconnected to prevent short circuit and protect the DC charging pile body.
