Wind-solar hybrid charging equipment for electric vehicle

Abstract

The invention provides a wind-solar hybrid charging station for an electric vehicle. The energy of the charging station derives from electric energy converted by wind energy and solar energy which belong to renewable clean energy. The charging station comprises a charging energy storage unit and an independent electric power supply unit. The charging energy storage unit is used for providing the electric energy for a storage battery of the charging station for the electric vehicle, and the independent electric power supply unit is used for separately providing the electric energy for the charging energy storage unit. With the independent electric power supply unit, the wind-solar hybrid charging station for the electric vehicle can supplement the electric energy per se without a power grid and supplement the electric energy for an electric energy storage module of the charging energy storage unit by the electric power supply unit in the daytime or nighttime, so as to lead the wind-solar hybrid charging station for the electric vehicle in the invention to exist independently without being connected with the power grid and not to affect the work of the power grid, thereby not only eliminating the additional burden brought to the power grid and power generating equipment thereof due to that the present charging station for the electric vehicle needs to be connected with the powergrid, but also solving the charging problem of the electric vehicle in a remote area without the power grid.

Description

technical field [0001] The invention relates to a charging device for an electric vehicle, in particular to a wind-solar complementary charging device for supplementing electric energy for a power device of an electric vehicle. Background technique [0002] As we all know, motor vehicles need to provide energy by burning fuel when they are working. However, traditional fuel energy is limited, and it is constantly decreasing with people's use, and when using traditional fuels, it will also produce excessive emissions of 6 kinds of greenhouse gases such as carbon dioxide, and the harm caused by the greenhouse effect to the global environment As a result, renewable energy has received more and more attention from countries all over the world, and it is urgently hoped that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. [0003] Therefore, in order to solve the problems of resource shortage and environmental pollution,...

Problems solved by technology

[0005] However, the existing electric vehicle charging station is mainly connected to a dedicated power supply network, so when in use, it is prone to high-power power consumption, which interferes with the power network and affects the normal power consumption of other users in the same grid , and it is easy to damage the grid equipment, which is a major shortcoming of the existing electric vehicle charging station

[0006] Secondly, after the power supply of the grid stops supplying power, the energy storage box of the electric vehicle charging station cannot be supplemented with electric energy. Therefore, when the electric energy of the energy storage box is used up, other electric vehicles cannot be charged, resulting in motor failure. Cars cannot work due to insufficient electric energy, thereby causing troubles to people. As mentioned above, existing electric vehicle charging stations are easily affected by the grid because they are connected to the grid. This is another disadvantage of existing electric vehicle charging stations. shortcoming

[0007] In addition, at present, most of the electric energy of the power grid comes from the conversion of fossil energy such as oil, natural gas and coal, which generates a large amount of carbon emissions while generating electricity, and the greenhouse effect causes a large number of disasters to the earth.
