Abstract

The invention discloses a wireless charging receiving device, an electric car, and a wireless charging system. The device is used for charging a power battery, and comprises a receiving coil module, a charging circuit, a vehicle-mounted control circuit, a vehicle-mounted power supply, and a switching module. The receiving coil module is connected with the power battery through the charging circuit, and the vehicle-mounted control circuit is connected with the charging circuit. The vehicle-mounted power supply is connected with the power supply end of the vehicle-mounted control circuit through the switching module, and a conduction control end of the switching module is connected with the receiving coil module. When the receiving coil module generates an induction voltage for output, the switching module is connected, and the vehicle-mounted control circuit is switched on to control the charging circuit to work, so as to enable the receiving coil module to charge the power battery through the charging circuit. According to the technical scheme of the invention, the device can reduce the standby power consumption of a system.

Description

technical field

[0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging receiving device, an electric vehicle and a wireless charging system. Background technique

[0002] Currently, more and more electronic devices are charged by wireless charging, such as electric vehicles. In the existing wireless charging system of electric vehicles, in order to ensure that the on-board control circuit can respond at any time and start the charging circuit to start charging, therefore, the on-board control circuit and the on-board power supply are also in a connected state when not charging, that is, the on-board control circuit is always Keep the power on, so that there will be a certain static power consumption on the vehicle control circuit, resulting in limited system standby time. Contents of the invention

[0003] The main purpose of the present invention is to provide a wireless charging receiving device, which aims to redu...
