Abstract

The invention discloses an alternating current charging connection device and a temperature protection method. By detecting the real-time temperature of a power supply plug, corresponding switch is made on a CC loop, namely a vehicle connection confirming loop of the alternating current charging connection device; meanwhile, a counting rule is set, and when the temperatures are changed repeatedly,the CC loop can be permanently disconnected to protect the charging connection device and achieve safe electrification. Meanwhile, the invention relates to the charging connection device applying thetemperature protection method. By means of the alternating current charging connection device and the temperature protection method, the phenomena of outbreak of a fire, burning and the like caused when the temperature of the power supply plug is too high can be effectively avoided, and it is ensured that electric vehicles are safely charged.

Description

technical field [0001] The invention belongs to the technical field of manufacturing electric vehicle charging equipment, and in particular relates to a temperature protection method for a power supply plug of an AC charging connection device, and the invention also relates to the charging connection device of the method. Background technique [0002] With the continuous maturity of electric vehicle technology, the electric vehicle industry has gradually gained the favor of the public, making more and more people choose electric vehicles as a necessary means of transportation. Electric vehicles have the advantages of zero emission and energy saving, so the market share of electric vehicles is gradually increasing. However, during the charging process of electric vehicles, the charging device is often burned due to the overheating of the power supply plug, and may even cause personal safety hazards such as electric shock and fire. Based on this, it is necessary to study a br...
