Embodiment 1

[0026] An electric vehicle charging system of the present invention includes a charging control system, a charging machine, and a charging pile. Among them, the charging control system includes a controller and a basic module unit for connecting the charger and the charging pile. The basic module unit has at least two levels. Each charger is connected to the charging pile through the basic module unit. An input interface, two output interfaces, and the input interface is strobe connected to the two output interfaces. The basic module unit of the last level of each charger is connected to all charging piles, and the last level refers to the basic module unit whose output interface is not connected to any basic module unit. The controller is connected to at least two chargers, and each charger is connected to the charging pile through at least two levels of basic module units. Power transmission branch.

[0027] In the present invention, a tree-shaped basic module unit is set...

Embodiment 2

[0031] Such as image 3 The basic module unit shown is provided with 1 input interface, 2 output interfaces, 2 CAN communication interfaces, and 2 485 communication interfaces, and a switch is connected between the data interface and the output interface, and the conduction of the switch There is a centralized controller control for shutting down. centralized controller such as Figure 4 As shown, there are 3 CAN communication interfaces, which are respectively responsible for communicating with the charging pile, charger, and basic module.

[0032] The electric vehicle charging system mainly composed of the above-mentioned basic module units and a centralized controller is as follows: figure 2 As shown, the centralized controller connects charger 1# and charger 2# through the communication interface CAN1, that is, charger No. 1 and charger No. 2, and the two chargers are connected through their respective first-level modules and second-level modules. Charging pile, wherei...

Abstract

The invention relates to an electric automobile charging system and a charging control system. Basic module units with tree structures are arranged between a charger and a charging pile to connect thecharger with the charging pile; at least two stages of basic module units are arranged; and a controller performs matching between the charger and the charging pile by controlling the on-off of the basic module units and gating a branch circuit for connecting the charger with the charging pile. The circuit design is simple; the circuit design cost is low; any charger can supply power to any charging pile; and redundancy and reliability of the charging system and the charging control system are improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to an electric vehicle charging system and a charging control system. Background technique [0002] With the development of electric vehicles becoming more and more perfect, and the national technical support policy for new energy vehicles, the blueprint for the quantitative production of electric vehicles has gradually become clear. In the future, the development of electric vehicles must be the major direction of the automobile industry. Electric vehicle charging station is a very important part of electric vehicle supporting products. [0003] Compared with the integrated charging pile, the centralized control solves the problem of heat dissipation and IP protection of the charging machine, and can reduce the area occupied by the charging pile. The construction of the charging station is gradually separated from the integrated charging machine to th...
