A lid system is a system including a plurality of lids of a vehicle, the system including: a first lid that covers a power supply port that receives AC power, the first lid being openable and closable; a second lid that covers a power supply port that receives DC power, the second lid being openable and closable; a lid opener for opening the first and second lids; a position detecting unit that detects a current position of the vehicle; and an ECU that controls the lid system. The ECU obtains positions of power supply facilities of the AC power or the DC power, specifies a power supply facility located at a position close to the current position detected by the position detecting unit, and performs a prescribed process for opening, by the lid opener, the lid corresponding to an energy source supplied by the specified power supply facility.
