The invention provides a power supply circuit, a power supply method and an automatic driving vehicle, and relates to the technical field of electrics, in particular to the technical field of power supply control. According to the specific implementation scheme, a control unit is connected with a pre-charging unit and a wake-up signal input end, and is configured to respond to a wake-up signal not received from the wake-up signal input end and output a starting signal to the pre-charging unit; in response to the received wake-up signal, outputting a turn-off signal to the pre-charging unit; the pre-charging unit is connected with the energy storage unit and is configured to output a first charging voltage to the energy storage unit in response to the received starting signal; in response to the received closing signal, stopping outputting the first charging voltage; the protection unit is connected with the wake-up signal input end and the energy storage unit, and is configured to output a second charging voltage to the energy storage unit in response to the received wake-up signal; the energy storage unit is configured to receive the first charging voltage or a second charging voltage and store electric energy, and the second charging voltage is larger than the first charging voltage.
