Charging gun head end do not have temperature protection function, when charging, if charging gun head part breaks down, can cause rifle hair heat to a great extent, but owing to not having temperature detecting function, on cable, controller cannot judge, charging gun head can not stop work; Heat accumulation is increasing causes socket and plug short-circuit conditions occur, and serious even can cause fire.
Summary of the invention
ThisInventionObject just be provide one solve the problem; can can send signal in time in charging gun head temperature anomaly situation and inform control enclosure on cable; and stop charging by the control of control enclosure on cable; high temperature is avoided to cause rifle head fault; after temperature return is normal, the new-energy automobile charging gun of a kind of charging gun headband temperature protection function that can automatically again charge.
In order to realize above-mentioned purpose, the technical solution used in the present invention is such: the new-energy automobile charging gun of a kind of charging gun headband temperature protection function, comprise control enclosure and charging gun head on charging plug, cable, described charging gun head comprises housing and is positioned at the jack of shell end, and described jack comprises CP signal wire jack, ground wire jack, firewire jack and zero line jack;
On described cable, control enclosure comprises shell, is positioned at the microprocessor of shell and power supply control apparatus, described power supply control apparatus comprises PWM output terminal and PWM monitoring side, described PWM output terminal connects CP signal wire jack, and described PWM output terminal is connected between PWM output terminal and CP signal wire jack;
Being provided with a temperature controlled switch in described housing, described temperature controlled switch is fixed on enclosure interior, and two ends are grounding wire jack and CP signal wire respectively; Housing is also provided with the maintenance mouth of maintenance temperature controlled switch;
The charging live wire of plug, zero line, ground wire are directly connected with the firewire jack of charging gun head, zero line jack, ground wire jack, and are respectively equipped with switch on live wire, zero line.
As preferably: described temperature controlled switch is positioned at housing near shell end place.
As preferably: the switch arranged on live wire, zero line is positioned at the enclosure of control enclosure.
Compared with prior art, it is an advantage of the current invention that: circuit structure is simple, without the need to redesigning charging gun circuit, do not increase controller, do not increase the communications cable, temperature controlled switch is placed in enclosure interior, do not affect charging gun one-piece construction, adopt temperature controlled switch to interfere the mode of CP signal, just reach the object automatically charged according to temperature control. Overcome in prior art, signal can not be sent in time in charging gun head temperature anomaly situation and inform control enclosure on cable, cause that heat accumulation is increasing causes socket and plug short-circuit conditions occur, the serious defect that even can cause fire.
In the present invention, when temperature exceedes the saltus step temperature of temperature controlled switch, temperature controlled switch closes, CP signal and ground wire are connected, being drawn by waveform signal low, on cable, the PWM monitoring side of the power supply control apparatus in control enclosure cannot detect normal CP signal, and microprocessor will cut off the switch on live wire, zero line, making charging plug stop being powered by charging gun head, charging gun head cannot charge. Working as decrease in temperature, during lower than the saltus step temperature of temperature controlled switch, temperature controlled switch is opened, and CP signal and ground wire are disconnected, and CP signal recuperation is normal, and microprocessor closes the switch on live wire, zero line, and charging gun head normally charges.
