Electric automobile group charging device and system

Abstract

The invention discloses an electric automobile group charging device and a system. The group charging device comprises an integrated charging box, and is characterized in that the integrated charging box outputs a plurality of charging cables, the charging cables are connected to charging plugging connection apparatuses, and the charging plugging connection apparatuses are arranged at parking spaces respectively. The integrated charging box is utilized to carry out centralized and unified management on charging conditions of the charging plugging connection apparatuses connected with the integrated charging box, thereby not only saving the occupied area, but also being convenient for centralized management and load allocation, being capable of carrying out centralized control on each charging branch circuit, and being completely controllable for each charging branch circuit. During charging, a terminal sends charging plugging connection apparatus information and charging parameters to a cloud server, the cloud server is communicated with a control system, the cloud server or the control system calculates a charging strategy, a switching device is controlled according to the charging strategy, and centralized intelligent charging is realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle group charging device and system for centralized parking lots. Background technique [0002] With the increasing awareness of environmental protection and energy saving, electric vehicles are gradually favored because they are powered by on-board power supplies, which can solve the problems of fuel vehicle exhaust emissions polluting the environment and high energy consumption. And the charging problem of electric vehicle is the problem that people pay close attention to very much, and it is related to popularization and promotion of electric vehicle. [0003] In the prior art, a charging station is usually provided in a parking lot, a residential area or an office building area, and a plurality of charging piles are arranged in the charging station. After the electric vehicle is parked, the electric vehicle is connected to the charging pile ...
