Abstract

The invention discloses a new energy automobile charging gun with a charging gun head achieving a temperature protection function. The new energy automobile charging gun comprises a charging plug, an on-cable control box and the charging gun head; the on-cable control box comprises an outer power supplying control device which comprises a PWM output end and a PWM monitoring end, the PWM output end is connected with a CP signal wire jack, and the PWM monitoring end is connected between the PWM output end and the CP signal wire jack; a temperature-controlled switch is fixedly arranged in a shell, and the two ends of the temperature-controlled switch are connected with a ground wire jack and a CP signal wire respectively; a live wire and a null wire are each provided with a switch. According to the new energy automobile charging gun with the charging gun head achieving the temperature protection function, the circuit structure is simple, and the purpose of automatically controlling charging according to the temperature is achieved by adopting the mode that the temperature-controlled switch intervenes in CP signals; the condition that in the prior art, due to the fact that a signal cannot be sent out in time to inform the on-cable control box on the condition that the temperature of the charging gun head is abnormal, heat is accumulated more and more, and a short circuit between a socket and the plug is generated is overcome.

Description

technical field [0001] The invention relates to a charging device, in particular to a charging gun for a new energy vehicle with a temperature protection function on the head of the charging gun. Background technique [0002] With the improvement of people's living standards, and the current trend of environmental protection, energy saving, and green ecological earth, electric vehicles are developing stronger and stronger with the strong support of the country, and their applications are becoming more and more extensive. The charging guns that match electric vehicles It also develops rapidly accordingly. [0003] Electric vehicles are charged through the charging cable when charging. The charging cable includes a charging cable head connected to the car. There are several charging jacks on the charging gun head, which are connected to the car and charged for the car. One of the jacks is the CP signal. line jack, connect the controller through the CP signal line, [0004] T...
