Electric vehicle, wireless charging system and wireless charging method

Abstract

The invention discloses an electric vehicle, which acquires wireless network access information and parking space information through an information acquisition module; an in-vehicle communication module accesses the wireless network according to the acquired wireless network access information, and in the accessed wireless network A communication connection with the communication service module is established according to the parking space information, so as to communicate with the charging server through the communication service module based on the established communication connection. The invention also discloses a wireless charging system and a wireless charging method. When the wireless charging system wirelessly charges the electric vehicle, the in-vehicle communication module can transmit information between the communication service module and the charging server based on the communication connection established above, so that the charging server can monitor the charging state of the electric vehicle in real time, and according to The charging state of the electric vehicle is processed accordingly, which improves the safety of the electric vehicle during wireless charging.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to an electric vehicle, a wireless charging system and a wireless charging method. Background technique [0002] Wireless charging is a technology that transmits electric energy in the air between the charger and the charged device through technologies such as electromagnetic induction, thereby charging the battery of the charged device. Compared with wired charging, wireless charging has the advantages of less leakage, fully automatic operation and unattended operation, so it has been widely used in electric vehicle charging technology. [0003] In the prior art, the secondary coil is installed on the electric vehicle, and the primary coil is installed on the parking space on the ground. When the electric vehicle is parked at the preset charging position on the parking space, the primary coil and the secondary coil form a loosely coupled transformer, and the high-frequen...
