Embodiment Construction

[0018] The intelligent on-line charging system for electric vehicles of the present invention will be described in detail below in combination with examples and accompanying drawings.

[0019] Such as figure 1 As shown, the 220v AC power is connected to the DC stabilized power supply (2), and after rectification, the optional DC output of 30v-180v is output to the transmitting device (3). To the primary side of the compensated loosely coupled transformer, realize resonant coupling with the receiving device (4), and convert it into direct current through the secondary rectification circuit (5), thereby supplying electric energy to the electric vehicle.

[0020] Such as figure 2 As shown, the 220v AC is stepped down by the transformer and sent to a rectifier bridge composed of 4 diodes, and then through the built-in required voltage stabilizer, the output is 30v-180v DC.

[0021] Such as image 3 As shown, the 30v-180v DC power is sent to two MOSFETs, which can be turned on ...

Abstract

The invention relates to an electric motor vehicle intelligent on-line charging system based on contactless power transmission technology, comprising a direct-current stabilized voltage power supply (2) (provided with a primary rectification circuit), an emission device (3) laid on the ground, a receiving device (4) and a secondary rectification circuit (5), wherein the receiving device (4) and the secondary rectification circuit (5) are mounted on an electric motor vehicle chassis. When charging the electric motor vehicle, it is only necessary to connect a 220v home common lighting power supply with the electric motor vehicle. When the electric motor vehicle is externally connected with an intelligent inductive switch, the electric motor vehicle is actively charged when the electric quantity is not enough and the charging process is automatically switched off when the electric quantity is full. The structure of the electric motor vehicle intelligent on-line charging system is convenient, intelligent and flexible. In case of not using an external electric wire, a contactless electric energy transmission technology is used to automatically, quickly and portably charge the electric motor vehicle, the energy is saved, the environment is protected, thus the electric motor vehicle intelligent on-line charging system is widely used by the home user and also used in the whole traffic service system.

Description

technical field [0001] With the maturity of non-contact power transmission technology, various electrical equipment and applications based on this technology will gradually enter the public life, providing intelligent and convenient services for people's daily activities. The so-called "wireless power transmission" is to use a special device to convert the electric energy of the power supply into energy that can be transmitted wirelessly, and then convert this energy back to electric energy at the receiving end, so as to achieve wireless power supply to electrical appliances. [0002] The present invention, the intelligent online charging system for electric vehicles, belongs to the broadest new application field of non-contact power transmission technology. The technical concept of energy saving, environmental protection, simplicity and convenience has been realized. Background technique [0003] Traditional electric vehicles require battery power, for which each electric ...
