Problems solved by technology

However, due to the non-centralized distribution of power devices between power modules, the charging station can only choose the air-cooled heat dissipation mode, which has a low protection level, resulting in high maintenance costs and low long-term operation reliability; in addition, this design scheme is difficult to achieve flexible control. The effective utilization of output power is low

Abstract

The invention discloses a novel flexible and intelligent charging station. The charging station comprises charging piles, a phase shift rectification unit, direct current energy storage units and MMC carrier phase shift direct current units. The invention also discloses a novel flexible and intelligent charging method. According to the invention, under the condition that charging requirements of all charging piles are larger than the stipulated required power, the number of the charging piles is limited through flexible control, so in case of certain input power, charging requirements of electric vehicles can be met to the greatest degree.

Description

technical field [0001] The patent of the invention belongs to the technical field of electric vehicle charging piles, and specifically relates to a flexible intelligent charging station and a flexible intelligent charging method. The invention is suitable for the construction of electric vehicle charging stations, and is used for charging medium and high-power electric vehicles. Background technique [0002] With the development of electric vehicles, the demand for charging piles and charging stations is increasing. Now the construction of charging piles has achieved certain achievements and has begun to be promoted on a large scale. With the further promotion of electric vehicles, the construction of charging stations is becoming increasingly urgent. The key factors in the construction of charging stations include charging efficiency, station construction costs and maintenance costs. [0003] At present, the charging station is generally realized by using 10kW / 15kW power m...
