Abstract: On the screen of a display unit, period border lines are displayed. The period border lines divide hours (for example 24 hours) for a user's desired one day into a plurality of periods and present line segments movable on the screen in a predetermined direction. Each of the line segments acts as a border lien between mutually adjacent periods. On the screen, target temperatures which are set for the respective periods are also displayed. Dragging the period border liens (K1 to K4) so as to move on the screen makes it possible to move a start time and a stop time of mutually adjacent periods are changed simultaneously. In addition to this change, target temperatures which were set before the change are reset for changed periods.

Abstract: A cooling system for cooling a main battery 10 includes a cooling fan 40 and a temperature sensor 61 configured to detect a battery temperature TB. The cooling system performs constant control in which the cooling fan 40 is driven at a constant command value when the battery temperature TB reaches or exceeds a first temperature T0 after startup of the electrically powered vehicle. Additionally, the cooling system detects whether or not a malfunction occurs in the cooling fan 40, based on an actual rpm of the cooling fan 40 obtained during the constant control. The cooling system performs the constant control in a situation in which charging of the main battery 10 is continued for a predetermined period of time or longer after the startup of the vehicle, regardless of whether the battery temperature TB is below the first temperature T0.
