Description

A kind of wind-solar hybrid charging equipment that is used for electric motor car

Technical field

The present invention relates to a kind of electric motor car charging device, be meant that especially a kind of is the wind-solar hybrid charging equipment of the electric device electric energy supplement of electric motor car.

Background technology

As everyone knows, motor vehicle need come locomotive that energy is provided through combustion fuel in work.Yet traditional fuel energy is limited; The use of its Along with people's and reducing constantly, and when using traditional fuel also can produce 6 kinds of greenhouse gas such as carbon dioxide simultaneously and excessively discharge; The greenhouse is imitated the harm that causes to global environment and is become increasingly conspicuous; Thereby regenerative resource receives the increasing attention in various countries, the whole world, hopes that urgently regenerative resource can change human energy resource structure, keeps long-range sustainable development.

Therefore in order to solve shortage of resources and environmental pollution problems, electric motor cars such as electric bicycle, electrocar, electric motor coach have obtained using widely.Yet required energy is to be provided by the storage battery that is arranged in the electric motor car during electric motor car work, and stored electric energy is limited in the well-known storage battery, and therefore after the power consumption in the storage battery was intact, electric motor car can not run well.For sort this problem out, various electric motorcar charging stations have appearred on the market, and fresh combatants that will become automobile industry obtain fast development.And a key element supporting the electric automobile development is exactly the guarantee of charging and the reasonable disposition of charging station.

Prior electric car charging station, it mainly is to be that energy storage case in the charging station charges through electrical network, then when electric motor car need charge, is that the storage battery of electric motor car charges by electric energy stored in the energy storage case then.Thereby the problem that the battery power in the solution electric motor car is not enough.

Yet it mainly is connected prior electric car charging station with special-purpose supply network; Therefore in use; The phenomenon that occurs the high power power taking easily to such an extent as to disturb power utilization network, influences other users' in same electrical network normal electricity consumption; But also damaging grid equipment easily, this is a big shortcoming of existing electric motorcar charging station.

Secondly, after the supply of electric power of electrical network is stopped power supply, then can't carry out replenishing of electric energy for the energy storage case of electric motorcar charging station; Therefore after the electric energy of energy storage case uses, then can not charge, thereby cause electric motor car can't work, thereby make troubles to people because of electric energy is not enough for other electric motor car; As stated; Prior electric car charging station is owing to be connected with electrical network, so receive the influence of electrical network easily, this is the another shortcoming of existing electric motorcar charging station.

In addition, the electric energy majority of electrical network produces a large amount of carbon emissions from the conversion of fossil energies such as oil, natural gas and coal in generating at present, and greenhouse effect cause a large amount of disasters to the earth.

Summary of the invention

The present invention provides a kind of electric motor car wind light mutual complementing charging station; The independent power feed unit that it comprises that the storage battery that is used to electric motorcar charging station provides the charging energy-storage units of electric energy and electric energy is provided separately for this charging energy-storage units; Make the electric motor car wind light mutual complementing charging station of the present invention need just can be through this independent power feed unit to self not carrying out replenishing of electric energy through electrical network; Wherein this independent power feed unit comprises wind energy is converted into the first wind-powered electricity generation converting unit of electric energy and is the photoelectric conversion unit of electric energy with transform light energy; This first wind-powered electricity generation converting unit and this photoelectric conversion unit are arranged at the top of this charging energy-storage units, and this photoelectric conversion unit is arranged at last aspect light one side of this charging energy-storage units.
