Reservation electric vehicle charge method on basis of road-station-vehicle joint models

Abstract

The invention discloses a reservation electric vehicle charge method on the basis of road-station-vehicle joint models. The reservation electric vehicle charge method includes 1), acquiring vehicle state information, road condition information, charge station state information and optimal control parameters set by users; 2), planning travel paths for electric vehicles from current locations to various charge stations according to the vehicle state information, the road condition information and the charge station state information; 3), determining reservation charge scheme sets; 4), planning travel paths for the electric vehicles from the charge stations to destinations according to the vehicle state information, the road condition information and the charge station state information; 5), determining the optimal travel paths according to requirements of the users of the electric vehicles and carrying out charge reservation. The reservation electric vehicle charge method has the advantages that journey demands and charge demands of the users of the electric vehicles are comprehensively considered, charge station reservation charge service which can meet requirements can be selected for the users of the electric vehicles with charge demands, and the reasonable travel paths can be planned for the users of the electric vehicles.

Description

technical field [0001] The invention relates to a reserved charging method for an electric vehicle based on a combined road-station-vehicle model, and belongs to the technical field of electric vehicles. Background technique [0002] The depletion of global energy and resources and the crisis of ecological environment deterioration have promoted the development of the electric vehicle industry. Compared with traditional vehicles, electric vehicles (EV) use electric energy instead of fossil energy as power, which can effectively reduce greenhouse gas emissions and slow down the consumption of fossil energy. Under the global environment of advocating energy conservation and emission reduction, the United States, Japan, Europe and China have successively introduced a series of plans and policies to encourage the development of the electric vehicle industry. However, electric vehicles are still in their infancy, and charging infrastructure such as charging piles needs to be deve...

Problems solved by technology

Under the global environment of advocating energy conservation and emission reduction, the United States, Japan, Europe and China have successively issued a series of plans and policies to encourage the development of the electric vehicle industry. However, electric vehicles are still in their infancy, and charging infrastructure such as charging piles needs to be developed Perfect, charging resources are limited, therefore, it is particularly important to solve the charging problem of electric vehicles

[0003] Electric vehicles are very different from traditional fuel vehicles, mainly reflected in their energy supply methods. Compared with traditional vehicles, electric vehicles take a long time to charge, and due to insufficient coverage of charging stations, charging resources are limited. The charging station cannot inform the electric vehicle owner of the busy status of the charging pile in time, which may cause the electric vehicle to arrive at the charging station and cannot be replenished as soon as the traditional car arrives at the gas station.

At present, the battery life of electric vehicles is also an important factor restricting the development of electric vehicles. At present, there is no navigation specially developed for electric vehicles. It is necessary to plan a suitable path for electric vehicles with insufficient battery life and navigate them to suitable charging stations.

Therefore, the existing technology on electric vehicle charging still needs to be improved and developed.
