The invention discloses a vehicle-mounted intelligent power supply system, and relates to the technical field of vehicle-mounted power supplies. The system comprises various high-voltage load drives such as heater drives, and various drives are integrated together, so that overall management and safety management are facilitated; according to a transformer principle, high-voltage direct current is reduced into 12V and 48V low-voltage direct current for low-voltage load driving, a controller and a sensor are used for supplying power to a low-voltage high-power load, 48V driving is adopted, driving current is reduced, load loss is reduced, a small-capacity lithium battery is used for replacing an original lead-acid battery, and the use cost of the whole life cycle is reduced. The weight of the battery is reduced; through a CAN (Controller Area Network) or LIN (Local Interconnect Network) bus, the control of each driving part and each power supply module is realized, and meanwhile, an acquisition signal of a sensor is reported; external power supplies which may appear in the future are added into an overall management range, and a vehicle electric appliance framework in the future development direction of intelligent automobiles is met.
