Wake-up device for wireless charging system of low-power consumption electric vehicle

The invention discloses a wake-up device for a wireless charging system of a low-power consumption electric vehicle. The wake-up device includes an auxiliary power supply, a charging circuit, a controller and a communication circuit connected with the controller. The charging circuit includes a starting switch, and the charging circuit is used for controlling the auxiliary power supply to power the whole wake-up device after the starting switch is switched on. The controller is used for detecting whether the communication circuit receives a pulse signal sent by a wireless charging transmittingterminal in a preset time period or not after power is supplied, if the pulse signal is received, a feedback signal is sent to the transmitting terminal through the communication circuit for the transmitting terminal to start charging; and if the pulse signal is not received or charging is finished, the charging circuit is controlled to be disconnected from the auxiliary power supply. According to the wake-up device for
