Abstract: PROBLEM TO BE SOLVED: To suppress charging of a battery with excessive power.
SOLUTION: When an air conditioner actuation request is made with the power plug of a charger connected to a commercial power supply after a vehicle system is stopped, a power obtained by adding a requested charging power Wchg to a requested air conditioning power Wac* is set as a temporary requested power Wtmp (Step S110). A value obtained by limiting the set temporary requested power Wtmp with the absolute value |Win| of input limit Win is set as a requested power W* (Step S120). The switching elements of the AC/DC converter and the DC/DC converter of the charger are switching controlled so that the power supplied from the charger becomes equal to the requested power W* (Steps S130). The charger is controlled so that the set requested power W* is supplied within the range of the input limit Win, thereby charging of the battery with an excessive power exceeding the input limit Win can be suppressed.
