Abstract
A power supply device for a vehicle includes first and second systems, a switch disposed between the systems, and first and second controllers. The first system includes a first power supply and a first electrical apparatus. The second system includes a second power supply and a second electrical apparatus. The first mode controller executes a low power mode where the switch is turned on to supply electric power from one of the first and second power supplies to the first and second electrical apparatuses. The second mode controller executes a high power mode where the switch is turned off to supply electric power from the first and second power supplies to the first and second electrical apparatuses, respectively. When a discharge electric current of the second power supply exceeds a threshold during the low power mode, the second mode controller switches the power supply mode to the high power mode.
