Electric vehicle automatic charging control method used for private person

Abstract

The invention discloses an electric vehicle automatic charging control method used for a private person. The method includes the steps that a charging time period range is selected according to charging finishing time node information set by a user, and the time period range is divided into multiple small subsections according to certain time length; according to battery state information, the charging time length is determined and is namely the number of the small subsections needing charging, and the charging probability of each electric vehicle on each small subsection is calculated; a random number within the range (0, 1) is taken at will on each small subsection for each electric vehicle and compared with the corresponding charging probability, so that whether the vehicle is charged on the subsection or not is determined until the whole process of charging all the vehicles is finished. According to the technical scheme, communication among the electric vehicles within the range and communication between the electric vehicles and a superior power grid do not need to be established, the method is not affected by other electric vehicles, and a lot of basic facilities and management resources of the electric vehicles are omitted. The charging cost of the user can be reduced, and meanwhile influences on the power grid by charging loads can be reduced.

Description

technical field [0001] The invention relates to a charging control method, in particular to an autonomous charging control method for private electric vehicles. Background technique [0002] Climate change, energy and environmental issues are long-term issues faced by human society. As non-renewable energy such as petroleum is facing exhaustion, excessive emissions of greenhouse gases have led to global warming, and the traditional automobile industry urgently needs structural upgrades to realize power system The strategic transformation of electrification. As a new generation of transportation, electric vehicles can meet the requirements of zero emission and low noise, and are an important means to solve energy and environmental problems. The continuous development of battery technology has continuously improved the economic performance of electric vehicles. The new generation of energy-saving and environmentally friendly vehicles represented by electric vehicles is an ine...

Problems solved by technology

[0004] Through the analysis of the existing domestic and foreign literature, the existing control strategies for electric vehicle charging all need to establish a central dispatching system to communicate with each charging device and the power grid to obtain information about each charging device. Relevant control strategies are given for different goals such as reducing line loss, etc., which require the cooperation of supporting facilities and electric vehicle users, making charging more troublesome and not conducive to user acceptance
