New energy automobile charging pile

Abstract

The invention belongs to the technical field of charging piles, and particularly relates to a new energy automobile charging pile which comprises a pile body, a heat dissipation part, a charging assembly and a charging gun head. According to the charging pile, air circularly flows inside and outside the pile body under the action of the cooling fan, and heat generated by the charging assembly and the charging cable is brought out of the pile body in the air flowing process, so that excessive heat is prevented from being accumulated in the pile body, and the temperature in the pile body is reduced; the cooling fans are arranged on the periphery of the charging assembly, so that air around the charging assembly is quickly exhausted, heat in the pile body is quickly reduced, the pile body is quickly cooled. Meanwhile, the internal resistance of the charging assembly and the charging cable is prevented from being increased by high temperature, loss caused by increase of the internal resistance is avoided, electric energy loss is reduced. Furthermore, the electric energy is saved; Meanwhile, the cooling fan carries out omnibearing heat dissipation on the charging assembly, so that excessive local accumulated heat of the charging assembly is prevented, and the local temperature of the charging assembly is prevented from being too high.

Description

technical field [0001] The invention belongs to the technical field of charging piles, in particular to a new energy vehicle charging pile. Background technique [0002] New energy vehicles refer to the use of unconventional fuels (electric energy, natural gas, solar energy, hydrogen energy, oil-electric hybrid, etc.) It has less impact on the air and is more and more popular among people. Among new energy vehicles, pure electric vehicles or gasoline-electric hybrid vehicles are relatively mature, and have the advantages of advanced technology, low cost, strong power, fast speed-up, and low pollution. Pure electric vehicles need to use charging piles for charging. During the charging process, charging cables and charging components will generate a lot of heat (especially fast charging piles). If the heat cannot be dissipated in time, the temperature of charging components and charging cables will As the temperature rises, it will affect the normal operation of the charging ...

AI Technical Summary

Problems solved by technology

The invention is mainly used to solve the problem that due to the low heat dissipation efficiency of the existing charging piles, the heat generated during the charging process cannot be eliminated in time. When the ambient temperature is high or the continuous charging time is too long, excessive heat will be accumulated in the charging piles. As a result, the temperature of the charging component and charging cable is too high, which affects the normal operation of the charging component and charging cable and reduces the charging efficiency. Loss, resulting in waste of electric energy, will also accelerate the aging of the insulating rubber in the charging pile, shortening the service life of the charging pile
