Abstract

The invention discloses an electric vehicle charging station management system and method. The electric vehicle charging station management system comprises a controller, N charging modules and M N-circuit selectors, the M N-circuit selectors are in one-to-one corresponding connection with the N charging modules, control ends of the N-circuit selectors are connected with the controller, and N-circuit selection ends of the N-circuit selectors are in one-to-one corresponding connection with the N charging modules. According to the management system, circuit states in the multi-circuit selectors corresponding to charging piles are controlled according to required power and a control algorithm, so that the number of the charging modules connected to the charging piles is timely adjusted, charging power of an electric vehicle is dynamically adjusted, charging requirements of the electric vehicle are met, power redundancy of the charging piles is decreased, the charging modules are configured in a centralized manner, power sharing between the charging piles is achieved, the problem of idle power resources is solved, the charging efficiency of the charging piles is improved, the overall utilization rate of a charging station is increased, resource is saved, and investment cost of the charging station is reduced. The invention further discloses a controller of the electric vehicle charging station.

Description

technical field

[0001] The invention relates to the technical field of electric vehicle charging, in particular to a management system, controller and method of an electric vehicle charging station. Background technique

[0002] With the development of electric vehicles, the application of charging stations for electric vehicles is becoming more and more extensive. Existing charging stations include multiple independent charging piles. The maximum charging power of each charging pile is determined by the charging power and quantity of the charging modules installed with it. Once the installation and construction are completed, the maximum charging power of the charging pile will be Fixed, cannot be adjusted. Please refer to figure 1 , figure 1 It is a schematic diagram of charging characteristics of an electric vehicle in the prior art. The charging characteristics of electric vehicles are divided into constant current stage and constant voltage stage. In the constant cu...
