Problems solved by technology
However, because contact charging requires contact, high voltage and large current are passed between the contact points instantaneously, which is potentially dangerous, and is easily affected by pollution, rain, etc., making contact charging not the best charging method.
In non-contact charging, due to the long transmission distance and small power transmission of electromagnetic resonance wireless charging, it is difficult to meet the safe and fast charging requirements of electric vehicles.
In addition, the existing charging system cannot realize automatic identification and charging of electric vehicles driving into the charging area.

The invention discloses a wireless automatic charging device for an electric vehicle, which comprises a fixed electric energy transmission system, a mobile electric energy receiving system and an electric vehicle battery. The fixed electric energy transmission system comprises a fixed communication unit, a central processing unit, an electric energy input end and an electric energy regulation andcontrol transmission unit. The mobile electric energy receiving system comprises a mobile communication unit, an electric energy receiving unit and a charging management device. The charging management device comprises a charging central processing unit, a charging detection module and a DC / DC conversion unit. The electric vehicle battery is in wired connection with the charging detection module and the DC / DC conversion unit. The invention discloses the wireless automatic charging device. Due to the adoption of the technical scheme, the charging management device is arranged to detect whetheran electric vehicle is in a charging area or not, read the type of the battery of the electric vehicle and automatically charge the battery of the electric vehicle, so that the wireless automatic charging device can realize automatic charging after the electric vehicle enters the charging area.
Description
technical field [0001] The invention relates to a charging device, in particular to a wireless automatic charging device for electric vehicles. Background technique [0002] The common electric vehicles in the market are driven by electric energy, which has the characteristics of environmental protection and less pollution. Therefore, electric vehicles have been highly valued. Countries such as Europe, the United States and China have invested heavily to encourage scientific research institutions and enterprises to promote the research and development and production of electric vehicles. At the same time, there are certain subsidies for the purchase of electric vehicles. However, due to the limited electric energy stored in electric vehicle batteries, it cannot meet long-distance long-distance driving, which seriously restricts the development and promotion of electric vehicles. How to replenish electric energy in time and quickly has become one of the key factors for the ...
