A main battery and a sub-battery serving as an auxiliary power source are provided to supply electric power to auxiliary machinery groups Hto H. In the state of normal power supply by the main battery, when the main battery is not degraded (step S: NO), a lower limit value of SOC of the sub-battery is set equal to 0% (step S). When the main battery is degraded (step S: YES), on the other hand, the lower limit value of SOC of the sub-battery is set equal to a predetermined maximum value (step S).

Power supply control device and power supply control method

An estimated temperature range is calculated by adding a plus-side temperature width to the temperature detected by a temperature sensor within the cabin of a vehicle and subtracting a minus-side temperature width therefrom, and is displayed on the display of a mobile terminal as a temperature state of the cabin. When cooling is performed, the plus-side temperature width is made greater than the minus-side temperature width. Also, the plus-side temperature width is narrowed with elapse of time from the start of pre-air-conditioning. With this operation, the temperature state of the vehicle cabin from the start of the pre-air-conditioning can be properly communicated to a vehicle user.

A display apparatus includes a display section which is attached to an electric vehicle EV operable upon supply of electric power thereto and displays information regarding the electric power supplied to the electric vehicle EV; a determination section which determines whether or not the electric power supplied to the electric vehicle EV contains green electric power; and a display control section. In the case where the determination section determines that the electric power supplied to the electric vehicle EV contains green electric power, the display control section controls the display section such that the display color becomes green. In the case where the determination section determines that the electric power supplied to the electric vehicle EV does not contain green electric power, the display control section controls the display section such that the display color becomes red.
