Charging gun adhesion detection device and method thereof

Abstract

The invention discloses a charging gun adhesion detection device and a method thereof, and particularly relates to the technical field of new energy charging piles, the charging gun adhesion detection device comprises a charging gun assembly, the charging gun assembly comprises a box body and an electric wire, one side of the box body is movably provided with a first shell and a second shell, the bottom of the box body is movably provided with a sleeve, and the electric wire is fixedly arranged at the bottom of the sleeve. When the charging pile is in the non-charging state, a controller controls the intermediate relay to be closed, a direct current contactor cannot be started at the moment, after the intermediate relay is closed, the switching power supplies are additionally arranged at the positive electrode end and the negative electrode end of the charging gun assembly, if the intermediate relay is closed, the controller receives a closing signal, and it is indicated that the charging gun assembly is short-circuited, on the contrary, the charging gun assembly is normal, after the charging pile detects that the charging gun assembly is connected with the automobile, the controller controls the intermediate relay to disconnect the detection circuit, the short circuit detection assembly is used for carrying out short circuit detection on the charging gun assembly, and the safety of the charging pile in use is greatly improved.

Description

technical field [0001] The invention relates to the technical field of new energy charging piles, and more specifically relates to a charging gun adhesion detection device and method. Background technique [0002] At present, the function of the charging pile is similar to that of the fuel dispenser in the gas station. It can be fixed on the ground or on the wall, and installed in public office buildings, shopping malls, parking lots, etc. and in the parking lot of living quarters. Various types of new energy electric vehicles are charged. With the country's vigorous promotion of electric vehicles, the number of charging piles has gradually increased. In recent years, with the improvement of battery technology and charging technology, the charging rate has become larger and larger. Charging piles The power of the charging pile is getting higher and higher, and the requirements for the manufacturing technology of the charging pile are getting higher and higher. [0003] Howe...

AI Technical Summary

Problems solved by technology

[0003] However, in the current national standard process, there is no short-circuit detection process for the charging gun before the charging pile is charged. Therefore, sometimes the vehicle or charging pile is damaged due to the short-circuit of the charging gun, and the use safety is low.
