The invention provides a wireless charging system, including: ground equipment and vehicle-side equipment; the ground equipment includes a first wireless communication module; the vehicle-side equipment includes a wake-up circuit, an auxiliary power supply, a second wireless communication module, a power circuit and a vehicle controller ; The wake-up circuit is used to receive the wake-up signal, and under the control of the wake-up signal, controls the connection between the power supply circuit and the auxiliary power supply, so that the power circuit sends a driving voltage signal to the auxiliary power supply; the auxiliary power supply is used to control the connection between the power supply circuit and the auxiliary power supply according to the driving voltage signal Send the first control signal to the second wireless communication module; the second wireless communication module is used to send a vehicle wake-up signal to the vehicle controller according to the wireless charging confirmation signal. In this way, the wake-up circuit can receive the wake-up signal, and can control the connection between the power supply circuit and the auxiliary power supply under the control of the wake-up signal. The second wireless communication module can send a wake-up signal to the vehicle controller, which can realize The entire vehicle wakes up the wireless charging system.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a wireless charging system. Background technique [0002] In the prior art, the whole vehicle cannot wake up the wireless charging system. For example, due to the power supply of the vehicle-end equipment, it has the function of waking up the whole vehicle. However, after the vehicle is powered off, it does not have the function of waking up the wireless charging system of the vehicle. Alternatively, the vehicle-end equipment has a high-voltage wake-up circuit, and this solution can wake up the entire vehicle. However, the whole vehicle cannot wake up the wireless charging system, that is, the whole vehicle cannot initiate the charging process. Therefore, in the prior art, the whole vehicle cannot wake up the wireless charging system. Contents of the invention [0003] Embodiments of the present invention provide a wireless charging system to solve the problem in the prior art th...
