Charging pile device of electric automobile

Abstract

The invention discloses a charging pile device of an electric automobile. The charging pile device comprises a base and a shell arranged on the upper side of the base. The shell is of a hollow structure. The inner portion of the shell is divided into a first cavity and a second cavity through a transversely-arranged separation board. The first cavity is located above the second cavity. A storage battery is arranged in the first cavity. The side wall of the shell is connected with a charging head through a connecting wire. The end, away from the charging head, of the connecting wire is connected with the output end of the storage battery. A heating device is arranged in the second cavity. An air compressor is further arranged on the side wall of the shell. The output end of the air compressor communicates with the second cavity. By the adoption of the charging pile device, the battery in the electric automobile can be preheated, the battery preheating efficiency is improved, and a quickcharging effect is achieved; meanwhile, the situation that the battery is charged at a low temperature and thus damaged is avoided, arrangement of the heating device for each automobile is avoided aswell, and waste of resources is reduced; and furthermore, the power load is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a charging pile device for electric vehicles. Background technique [0002] With the rapid development of social economy, my country has begun to pay more and more attention to the protection of the ecological environment. Under the national industry's focus and policy guidance, the development of electric vehicles is undoubtedly the best solution to the current environmental degradation, but in the process of great development Among them, there are still many problems that need to be solved. For example, the construction of charging piles has always been one of the problems restricting the rapid development of electric vehicles; at present, the charging effect of batteries in pure electric vehicles is poor below zero, and the batteries are easy to be damaged, and the normal operation of the batteries cannot be guaranteed. Charging works. The existing on-board power ba...
