Problems solved by technology

[0004] The driving range of electric vehicles is large and there is no fixed area. In order to replenish energy conveniently, electric vehicles need to be charged nearby. Therefore, electric vehicles and charging piles need to interact with different devices for each charging control, and the rated The current is not uniform, and the rated charging current that different charging points can provide may be different

Abstract

The invention discloses a self-adaptive charge control method based on wifi and applied to an electric automobile. The self-adaptive charge control method based on the wifi and applied to the electric automobile comprises the following steps that (1) charging point recognition is controlled, wherein a wifi module is installed in a charging point, a wifi vehicle-mounted terminal is installed on the electric automobile, and then control over charging point recognition is completed; (2) parameter configuration is controlled, wherein after communication, based on the wifi, between the electric automobile and the charging point is established and before charging is conducted, the electric automobile obtains a service which can be provided by the charging point from the charging point, the charging parameter is continued to be obtained from the charging point after the service suitable for the electric automobile is selected, a charging demand curve is calculated through weighting and is sent to the charging point through the wifi, in this way, planned charging can be conducted according to the charging demand curve, and a charging schedule is obtained; (3) the charging process is controlled; (4) charging stopping is controlled. According to the self-adaptive charge control method based on the wifi and applied to the electric automobile, the differences of charging points and the difference of charging parameters in different areas can be ignored, so that the charging requirement is met, the operation risk of a power grid is reduced, and the operation efficiency and the reliability are improved.

Description

technical field [0001] The invention relates to a wifi-based self-adaptive charging control method for electric vehicles, belonging to the technical field of charging control for electric vehicles. Background technique [0002] Electric vehicles can reduce human's dependence on oil resources. With the depletion of global oil resources, electric vehicles are favored compared with traditional fuel vehicles. Excessive emissions of global greenhouse gases have led to an intensified trend of climate warming. As a new generation of transportation, electric vehicles, because of their energy-saving and emission-reducing effects, governments around the world have introduced policy support, especially government subsidies, which have increased the market share of electric vehicles. [0003] After the large-scale application of electric vehicles, it will bring new challenges to the development of charging facilities and the operation of the power grid: triggering new load growth; putt...
