Intelligent direct-current charging gun of electromobile

Abstract

The invention relates to the technical field of electromobile charging, in particular to an intelligent direct-current charging gun of an electromobile. The intelligent direct-current charging gun of the electromobile comprises a red, green and blue LED indicator lamp embedded on the surface of a gun body, a buzzer is arranged at the position, close to the surface of the gun body, in the gun body, a temperature sensor is arranged at the position, close to the gun head, in the gun body, and a control circuit board is arranged in the gun body; a power line is drawn forth from a charging pile and supplies a power source to the control circuit board, a PE line of a direct-current charging interface serves as a ground line, and the control circuit board obtains connecting state signals of the direct-current charging interface through a CC2 line and a CC1 line of the direct-current charging interface and affects the charging process by intervening the CC1 line through a circuit; the red, green and blue LED indicator lamp is used for giving visual prompts different in color and frequency, and the built-in buzzer is used for giving auditory prompts. The intelligent direct-current charging gun provides more user-friendly and safer charging service for a user of an electromobile during charging.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle intelligent DC charging gun. Background technique [0002] Due to the shortage of oil resources and the constraints of the deterioration of the global environment, the sales of traditional vehicles powered by fuel and other non-renewable energy sources are slowing down year by year. Electric vehicles, which use electricity as an energy source, are a green vehicle with a very broad development prospect and an important choice to solve energy and environmental problems. Electric vehicle charging piles provide energy supply for electric vehicles and are an important supporting infrastructure necessary for the development of electric vehicles. The DC charging pile is a type of electric vehicle charging pile, and the DC charging gun is one of the essential components of the DC charging pile. [0003] However, the functions of DC charging guns cu...

AI Technical Summary

Problems solved by technology

[0003] However, the functions of DC charging guns currently on the market are generally relatively single, and can only provide the most basic functions necessary for charging, and the operation is not user-friendly enough.

[0004] 1) When an electric vehicle user lifts the charging cable and inserts it into the car charging seat, since the charging cable does not have any visual or auditory prompts, the user cannot immediately know whether the charging cable is inserted in place

[0005] 2) During the charging process, whether the charging is in progress, whether there is a fault in the charging, or whether the charging is over, the charging gun does not have any visual or auditory prompts. Although the user can check this information on the charging pile, it is still not very intuitive and convenient

[0006] 3) During the charging process, the tip of the charging gun is prone to overheating, but none of the existing charging guns on the market has a temperature protection function

[0007] 4) After charging, the user may forget to insert the charging gun back into the charging hole of the charging pile, but at this time the charging gun does not have any visual or auditory reminders

[0008] 5) When the charging gun is not inserted into the car charging stand, if the charging pile is abnormal, the metal part inside the charging gun head may be charged, which is potentially dangerous to the human body, but the charging gun does not have any visual or auditory warnings
