Abstract: A vehicle power management system and an operating method thereof are provided. The vehicle power management system is adapted for a vehicle load device and a vehicle power supply, and includes a control circuit, a charge/discharge circuit and a backup battery. The control circuit is electrically connected to the vehicle power supply and the vehicle load device, and monitors an output voltage of the vehicle power supply and determines according to the output voltage whether a vehicle engine is started. The charge/discharge circuit is electrically connected to the control circuit and the backup battery. When the vehicle engine is started, the charge/discharge circuit supplies power of the vehicle power supply to the backup battery and the vehicle load device. When the vehicle engine is not started, the backup battery discharges the charge/discharge circuit and the charge/discharge circuit supplies power of the backup battery to the vehicle load device.
