An ECU executes a program including a step of detecting a present location using a GPS
system (S1000); a step of reading out data of a geographical map
proximate to the present location (S1010) and presenting in the geographical map charging installations including a charging installation employing
solar light, together with the location of its vehicle (S1020); a step of, if a presentation switching request is made (YES in S1030) and a real-time solar
radiation correction request is made (YES in S1050), detecting a solar
radiation amount (S1060) and correcting a charge amount per unit time provided by the power generation installation employing
solar light, based on the detected solar
radiation amount (S1070); and a step of detecting an SOC in the battery to calculate an amount of
discharge done until arrival at the charging installation (S1080, S1090), calculating time required for charging up to a fully charged state (S1100), and presenting the time required for charging in the geographical map (S1200).
