Charging station

Abstract

A charging station comprises a plurality of charging piles; and each charging pile comprises a master control module, an interaction interface, a voltage conversion module, a charging gun, a first switch, a second switch, a communication interface and a parallel connection interface. When the master control module of a certain charging pile detects that the corresponding charging gun is connected with a charging interface of an electric automobile, and receives a parallel connection mode signal output from the corresponding interaction interface, the master control module sends a signal requesting establishment of a parallel connection relationship to the master control modules of the other charging piles so as to confirm whether the other charging piles allow the establishment of the parallel connection relationship or not. The charging pile and the charging piles allowing the establishment of the parallel connection relationship are connected in parallel, in the charging piles connected in parallel, each master control module controls the corresponding first switch to be turned on, and the power output by the charging piles is the power sum of the charging piles connected in parallel. The charging station can be connected with the idle charging piles in parallel to increase the output power of the single charging pile to meet the charging requirement of the electric automobile.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of electric vehicles, in particular to a charging station for electric vehicles. [0003] 【Background technique】 [0004] At present, the maximum charging power of each charging pile in the charging station is fixed, and some electric vehicles that can be fast charged with high power are often limited by the power of the charging pile and cannot achieve fast charging, which brings inconvenience to users. In addition, the charging piles in the charging station are available to users 24 hours a day. When the charging demand of charging station users is not saturated, the charging piles that are not used are all idle, resulting in a waste of resources. [0005] In view of the above, it is necessary to provide a new type of charging station to overcome the above defects. [0006] 【Content of invention】 [0007] The purpose of the present invention is to provide a charging station that can increase the ...

Problems solved by technology

[0004] At present, the maximum charging power of each charging pile in the charging station is fixed, and some electric vehicles that can be fast-charged with high power are often limited by the power of the charging pile and cannot achieve fast charging, which brings inconvenience to users.

In addition, the charging piles in the charging station are available to users 24 hours a day. When the charging demand of charging station users is not saturated, the unused charging piles are idle, resulting in waste of resources.
