Abstract

The invention discloses a wireless charging system for electric vehicles, comprising: a power supply device, a power receiving device and a battery manager, the power supply device is used to send a wireless charging device identification signal, and according to the identification information of the power receiving device and Battery information, which uses electromagnetic induction to transmit power to the power receiving device; the power receiving device, which is located on the electric vehicle, is used to detect whether there is a wireless charging device identification signal in the adjacent area; the battery manager is used to receive charging from the power receiving device Request, and after judging that the on-board power battery of the electric vehicle meets the preset charging conditions and receiving the charging command from the user, control the power receiving device to enter the wireless charging process, and obtain the battery information of the on-board power battery, and send the battery information to the electric energy receiving device. The invention has higher safety and reliability, and can improve the service life of the charging equipment.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a wireless charging system for electric vehicles. Background technique [0002] With the continuous promotion of new energy vehicles, especially electric vehicles or hybrid vehicles, new energy vehicles have become increasingly relevant to our daily life. At present, the charging method of electric vehicles is mainly wired charging, and the conventional charging method has the following shortcomings: [0003] First of all, the mobile handling of the equipment and the lead wire of the power supply are too long, mainly due to the cumbersome manual operation. Existing electric vehicles mostly use connection equipment for charging, and the connection equipment needs to be plugged and unplugged every time charging. In addition, there are also operational problems such as large and heavy connectors, which are difficult to insert and unplug. [0004] Secondly, the equipment...
