A vehicle power management system (VPM1) and an operating method thereof are provided. The vehicle power management system (VPM1) is adapted for a vehicle load device (L) and a vehicle power supply (P), and includes a control circuit (1), a charge/discharge circuit (2) and a backup battery (3). The control circuit (1) is electrically connected to the vehicle power supply (P) and the vehicle load device (L), and monitors an output voltage of the vehicle power supply (P) and determines according to the output voltage whether a vehicle engine is started. The charge/discharge circuit (2) is electrically connected to the control circuit (1) and the backup battery (3). When the vehicle engine is started, the charge/discharge circuit (2) supplies power of the vehicle power supply (P) to the backup battery (3) and the vehicle load device (L). When the vehicle engine is not started, the backup battery (3) discharges the charge/discharge circuit (2) and the charge/discharge circuit (2) supplies power of the backup battery (3) to the vehicle load device (L).
