Abstract

The invention provides an electric vehicle charging pile for automatically controlling and performing fire extinguishing, which comprises a charging pile body and a fire extinguisher. The charging pile body is connected with a charging plug. A thermal protector is connected between the charging plug and the charging pile body. The starting switch of the fire extinguisher is connected with a fire extinguishing switch through a wire rope. The fire extinguishing switch comprises a fire-fighting temperature sensing glass ball and a shaft core. The bottom end of the shaft core is connected with a spring. A lower bracket is arranged outside the shaft core. An upper bracket is arranged at inside of the housing. Two ends of the fire-fighting temperature sensing glass ball are respectively connected with the upper bracket and the lower bracket. The wire rope penetrates through the spring and is connected with the bottom end of the shaft core. Through the thermal protector, circuit opening is ensured when instantaneous current increase or high temperature occurs on the charging pile body, thereby preventing electric vehicle burndown caused by large current and ensuring safe charging to the electric vehicle. When a fire disaster occurs, the fire extinguishing switch is automatically switched on for performing fire extinguishing. Double insurances for the charging pile body and the charged electric vehicle are realized, and a better effect is obtained.

Description

technical field

[0001] The invention relates to an electric vehicle charging pile, in particular to an electric vehicle charging pile with automatic control and fire extinguishing. Background technique

[0002] Electric vehicles are powered by vehicle-mounted power supplies and driven by motors to drive wheels. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. At present, China's electric vehicles have entered the stage of industrialization from the research and development stage. As of the end of March 2012, more than 19,000 energy-saving and new energy vehicles have been promoted in 25 demonstration cities. Among them, there are 16,800 vehicles in the public service field, 170 charging (replacing) power stations, more than 6,400 charging piles, and more than 9 billion passengers.

[0003] However, the rate of fire caused by the charging pile heating is still high. To extinguish the fire with a fire extingu...
