Abstract

The invention provides a wireless charging system of an electric vehicle and a control method of the wireless charging system. A ground wireless charging device of the wireless charging system of theelectric vehicle comprises a ground end power coil and a ground controller; the ground end power coil comprises a transmitting coil and a foreign object detecting device which is used for detecting whether foreign objects exist on a wireless charging path of the transmitting coil or not; and the ground controller is connected with the ground end power coil to conduct foreign object early warning operation and / or foreign object early warning signal reporting when the foreign object detecting device detects that the foreign objects exist on the wireless charging path. According to the wireless charging system, the metal foreign objects influencing wireless electric energy transmission on the wireless charging path on the ground end power coil and the generated eddy effect can be detected inreal time, and thus safety of the wireless charging system is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a wireless charging system for electric vehicles and a control method thereof. Background technique [0002] Compared with contact charging methods such as charging piles, the power supply end and the electric vehicle in the wireless charging system do not need a direct electrical connection, and the wireless charging system can realize various intelligent automatic control and interaction. All new energy vehicle companies More and more attention is paid to the development and application of wireless charging systems. [0003] In the prior art, the basic types of wireless charging technology include electromagnetic induction, magnetic resonance, electric field coupling, microwave resonance, etc. Currently, electric vehicles usually use electromagnetic induction for wireless energy transmission. There is a problem that metal foreign objects in the coupling field of wireless c...
