Problems solved by technology

On the one hand, as the cruising range of electric vehicles becomes longer and longer, the battery capacity of the vehicles is also increasing; on the other hand, one of the widely criticized problems of electric vehicles is that the charging time of the car is much longer than the refueling time, and this problem has always been Troubled EV Alternatives
[0005] Second, there is a contradiction between the new charging facilities and the original distribution network load capacity planning
The load of electric vehicles has the remarkable characteristics of strong suddenness, short time, large capacity and uncertainty....

Abstract

The invention relates to a multi-mode electric vehicle charging system and a charging method thereof. The system comprises a power network interface, an energy storage device, a charging interface, anenergy exchange bus and an energy flow control device. The energy flow control device is connected with a charging service platform, a power grid dispatching system, an electric power trading marketand a vehicle owner through a communication network and exchanges information. The method comprises the following steps: the energy flow control device predicts the charging demand according to the charging demand related information and the regional charging demand statistical information, According to the electric power supply information, the electric power supply quantity is forecasted, and then the optimized energy storage plan is made according to the forecast information of charging demand quantity, electric power supply quantity, energy storage related information and vehicle owner's charging demand information, which gives consideration to both economy and guarantee supply. The invention can provide multi-mode charging service, thus satisfying the diverse charging requirements ofvehicle owners and avoiding large load impact to the power network.

Description

technical field [0001] The invention relates to a multi-mode electric vehicle charging system and a charging method thereof, belonging to the technical field of vehicle charging. Background technique [0002] In today's world, people are paying more and more attention to environmental issues. In order to improve the environment, the use of clean energy has reached a worldwide consensus. In particular, the use of electric vehicles to replace fuel vehicles to reduce emissions and control air pollution is widely respected by people. Governments around the world have formulated timetables for the replacement of electric vehicles. In recent years, with the development of technology, especially the development of battery technology, this trend of replacement is accelerating, and countries around the world are vigorously developing electric vehicles. At the same time, as another major field affecting the replacement of electric vehicles, charging technology is also making great str...
