Problems solved by technology

[0002] At present, the public charging stations for electric vehicles adopt on-grid charging, and the peak electricity price during the day is high and the load on the grid is heavy, which is not a small expense for electric vehicle users. If it is not handled properly, it will cause waste of social resources and environmental pollution. There is an urgent need for a charging station that can not only meet the needs of charging electric vehicles, but also can cut peaks and fill valleys on the power grid, and can also use retired power batteries.

Abstract

The invention belongs to the technical field of electric vehicle charging stations, and particularly discloses a semi-off-grid wind-solar complementary charging station which comprises a power supplysystem, an intelligent management system, an energy storage system and a charging pile charging system, and is characterized in that the power supply system comprises a wind power generation system, aphotovoltaic power generation system and a state grid power supply system. The charging station has low dependence on the power grid, Stepped utilization of retired power batteries can be realized, peak clipping and valley filling are carried out on the power grid, and the expenditure of an electric vehicle user is reduced and the remaining electric quantity is transmitted to the grid.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging stations, and in particular relates to a semi-off-grid wind-solar complementary charging station. Background technique [0002] At present, the public charging stations for electric vehicles adopt on-grid charging, and the peak electricity price during the day is high and the load on the grid is heavy, which is not a small expense for electric vehicle users. If it is not handled properly, it will cause waste of social resources and environmental pollution. There is an urgent need for a charging station that can not only meet the needs of charging electric vehicles, but also can cut peaks and fill valleys on the power grid, and can also use retired power batteries. . Contents of the invention [0003] The purpose of the present invention is to provide a semi-off-grid wind-solar complementary intelligent charging station, which has a low degree of dependence on the power grid, c...
