Embodiment Construction

[0047] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0048] Such as figure 1 Shown is the structural principle diagram of the embodiment of the grid-to-electric vehicle DC fast charging station management system of the present invention. It can be seen from the figure that the system includes a distribution network dispatching system, a distribution network energy management system, a DC fast charging station monitoring system, and a charging system. Machine controller and on-board controller, the DC fast charging station is managed by the distribution network energy management system and distribution network dispatching system at the same time. The distribution network energy management system issues real-time power limit commands to the charging station monitoring system, and the distribution network dispatching system issues daily "power consumption plans" to the DC fast charging stations. Th...

Abstract

The invention discloses a direct-current fast charging station managing system and method for an electric automobile from power grid. A power distribution network sends a power utilization plan to a direct-current fast charging station monitoring system, a power distribution network energy management system sends a real-time power limiting instruction to the direct-current fast charging station monitoring system, the direct-current fast charging station monitoring system sends a power limiting instruction to the electric automobile in a station according to the information issued by a power distribution network, a vehicle-mounted controller conducts responding on the power limiting according to the requirements of a user and automobile states, real-time coordination control is conducted on the electric automobile which is connected in, and the charging power of the electric automobile is controlled in real time. Coordination control among the power distribution network, the direct-current fast charging station and the user of the electric automobile is achieved.

Description

technical field [0001] The invention belongs to the technical field of management of DC fast charging stations for electric vehicles, and relates to a management system and method for a DC fast charging station for electric vehicles. Background technique [0002] The management of DC fast charging stations refers to the distribution network adopting certain incentives and measures to improve the power consumption characteristics of power users, improve the efficiency of terminal power consumption, and improve the operation efficiency of the distribution network while meeting the needs of users, so as to save resources, The purpose of protecting the environment and improving economic efficiency. DC fast charging stations for electric vehicles provide electric energy supply services for electric vehicles. Incorporating DC fast charging stations for electric vehicles into the scope of demand-side management of distribution networks is an important form of "orderly charging" for...
