Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such as figure 1 Shown is the structural principle diagram of the electric vehicle charging load space dispatching system of the present invention, the dispatching system includes

[0032] Electric vehicle on-board orderly charging controller 1 is used for the user to operate through the man-machine interface, and send the charging request, vehicle position coordinates, remaining mileage of the vehicle battery to the electric vehicle charging dispatching center via the wireless communication network (GPRS or 3G), The communication network (GPRS or 3G) receives the charging station allocation results issued by the electric vehicle charging dispatching center, and displays them on the man-machine interface to inform the electric vehicle users; the power grid dispatching unit 2 is responsible for giving whether the charging load of each charging station is evenly...

Abstract

The invention relates to a Charging-load space dispatching system for electric automobile and method therefor. The system comprises an electric vehicle ordered charging controller, a power dispatching unit and an electric vehicle dispatching center. Dispatching of the charging load space of an electric vehicle is achieved based on a charging request command, position information of the vehicle, and the residual electric quantity and the rated capacity of a vehicle cell, provided by the electric vehicle ordered charging controller, and also on a command about whether charging loads of all charging stations are uniformly distributed or not, provided by a power grid dispatching department. The problems of partial overloading and line congestion of power grids are solved.

Description

technical field [0001] The invention relates to a charging load scheduling system and method, in particular to an electric vehicle charging load space scheduling system and method. Background technique [0002] Facing the pressure of energy and environment, the development of electric vehicles and the promotion of low-carbon transportation are the focus of attention of the governments of China and major developed countries in the world. All countries have increased their policy support for electric vehicles. It can be expected that a large number of electric vehicle charging loads will be connected to the grid in the future. However, as a load that can be moved, the disorderly charging behavior of large-scale electric vehicles in time and space will not only cause the phenomenon of "peaking on top of the peak" of the power load, increase the peak-to-valley difference of the power grid, and may cause local overloading of the power grid. Problems such as load and line congest...
