The invention provides an intelligent power supply system and power supply method of a vehicle-mounted terminal. The intelligent power supply system of the vehicle-mounted terminal comprises a monitor circuit, an MCU processor, a driving circuit and a power supply circuit; the monitor circuit is used for monitoring whether a vehicle engine is in a start state or whether a vehicle is in a motion state, the MCU processor is used for generating a command to control the vehicle-mounted terminal to enter a dormant state according to a monitor result of the monitor circuit, the driving circuit is used for receiving and executing the command of the MCU processor, and the power supply circuit is used for supplying power to the whole intelligent power supply system. The intelligent power supply system and power supply method of the vehicle-mounted terminal have the advantages that the power consumption of the vehicle-mounted terminal can be reduced, the work currents are only in a milliampere grade when the vehicle-mounted terminal enters the dormant state, and the hidden trouble that the energy of a storage battery is used up due to the fact that a vehicle is not started for a long time is avoided.
