DC charging machine with charging gun temperature monitoring module and temperature control method of the DC charging machine

Abstract

The invention provides a DC charging machine with a charging gun temperature monitoring module and a temperature control method of the DC charging machine. The charging machine includes a main controller and a human-computer interactive display screen, a card swiping module, a power supply module, a charging gun temperature monitoring module, a power module, an insulation detection and discharge module and a DC power meter all connected with the main controller. The charging gun temperature monitoring module comprises a single-chip microcomputer and a debugging downloading unit, an acquisition control unit, a power conversion unit, a CAN1 bus and a CAN2 bus all connected with the single-chip computer which is connected with the charging gun through the CAN1 bus and connected with the main controller through the CAN2 bus. The power conversion unit is connected with the power supply module, and the acquisition control unit is connected with a K1 contactor, a K2 contactor and the charging gun separately. The charging gun temperature monitoring module can upgrade a charging gun of an existing charging pile, and through the technical scheme above, a temperature control method can be realized, which can effectively monitor the working temperature of the charging gun so as to ensure a safe and intelligent environment for a user.

Description

technical field [0001] The invention belongs to the field of temperature control of a charging gun of a charger, and in particular relates to a DC charger with a temperature monitoring module of a charging gun and a temperature control method. Background technique [0002] With the continuous improvement of battery capacity and production technology of electric vehicles, the advantages of low-carbon, environmentally friendly and green travel of electric vehicles have become more and more obvious. The output of electric vehicles has grown by leaps and bounds, and the demand for electric vehicle chargers is increasing. However, the charging gun of the previous charger does not have a temperature detection device. If it is used for a long time, the charging gun will age or the quality of the gun will cause the gun body to overheat and melt or even catch fire, which will bring great safety hazards to personal property. [0003] The standard for off-board conductive chargers for ...
