Wireless charging system with billing function

Abstract

The invention discloses a wireless charging system with a billing function. The wireless charging system with the billing function is characterized in that according to the wireless charging system, three-phase or single-phase AC electric energy of a power grid is changed into DC electric energy after being rectified by a transmitting rectifier, then the DC electric energy is converted into high-frequency AC electric energy through an inverter, and the high-frequency AC electric energy is transmitted out in an electromagnetic energy mode through a transmitting coil L1; a receiving coil L2 of an electric automobile receives electromagnetic energy and converts the electromagnetic energy into AC electric energy, the AC electric energy is converted into DC electric energy through a receiving rectifier, and the DC electric energy charges a battery pack after passing a DC converter; a contactor is arranged between the power grid and the transmitting rectifier, an upper computer is in communication with a receiving end control system of the electric automobile, and the contactor is controlled to charge the electric automobile after the identity of the automobile is determined. By the adoption of the structure, the identity of the charging automobile can be recognized, and a corresponding billing function can be achieved. The wireless charging technology can be better popularized.

Description

technical field

[0001] The invention relates to the field of wireless charging of electric vehicles, in particular to a wireless charging system with a billing function. Background technique

[0002] Compared with the traditional wired charging technology, the wireless energy transmission technology has the advantages of safety, reliability and convenient arrangement. With the popularity of electric vehicles, a large number of wireless charging piles will be arranged in parking lots in the future to charge electric vehicles.

[0003] However, the existing wireless charging technology does not have a billing function. In order to facilitate operation management and user use, a wireless charging technology with a billing function is obviously necessary.

[0004] It is a problem to be solved in the prior art to provide a new type of wireless charging system that can identify the identity of the charging vehicle and has a corresponding billing function. Contents of the invent...
