Electromobile charging station system with energy storing device and control method thereof

Abstract

The invention discloses an electromobile charging station system with an energy storage equipment, which comprises an alternate current supply power grid, monitoring equipment, charging equipment and energy storage equipment, wherein the alternate current supply power grid is accessed into the electromobile charging station system though a high-voltage relay protection cabinet, a three-phase transformer and a low-voltage relay protection cabinet; the monitoring equipment completes monitoring and control for the electromobile charging station system and guides the operation of the whole electromobile charging station system; the energy storage equipment contains a plurality of energy storage equipment groups, and each energy storage equipment group comprises a plurality of switch controllers and energy storing devices. The electromobile charging station system can effectively alleviate impact on the power grid, which is caused by quick charging, slow power grid pressure and provide charging service for different types electromobiles manufactured by different manufacturers. The electromobile charging station system has the advantages of convenient charging service, simple and flexible operation and convenient maintenance.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles and power systems, and in particular relates to an electric vehicle charging station with an energy storage device and a configuration and operation method thereof. Background technique [0002] With the increasingly serious energy crisis and the gradual enhancement of people's awareness of environmental protection, clean energy vehicles have been widely developed and popularized, among which the development technology of electric vehicles is the most mature. The charging forms of electric vehicles can be mainly divided into two types: battery pack replacement and charging station / pile charging. [0003] Due to the different power requirements and sizes of vehicles, limited vehicle space and great differences in layout, it is difficult to standardize the battery pack capacity, battery pack configuration and size required by different vehicles, and the charging method of replacing the bat...
