Patent ID: 8469857

Claim:
A vehicle comprising: an internal combustion engine as a driving source; a rotating electric machine as a driving source; a generator for generating electric power by a driving force of said internal combustion engine; a first battery for storing electric power supplied from a source external to a vehicle and electric power generated by said generator and supplying the stored electric power to said rotating electric machine; a second battery connected in parallel with said first battery, for storing electric power supplied from the source external to said vehicle and electric power generated by said generator and supplying the stored electric power to said rotating electric machine; and a control unit, wherein said control unit controls a state of charge of each of said batteries according to at least either one of a target range and a target value of the state of charge of each of said batteries, sets at least either one of the target range and the target value of the state of charge of each of said batteries so that the state of charge of said second battery is lower than the state of charge of said first battery by causing, when a condition that execution of charging with electric power supplied from the source external to said vehicle is predicted is satisfied, the state of charge of said first battery to be equal to or more than the state of charge of said first battery of the case where said condition is not satisfied and the state of charge of said second battery to be lower than the state of charge of said second battery of the case where said condition is not satisfied, and controls said internal combustion engine and said rotating electric machine so that said vehicle travels by a driving force of at least either one of said internal combustion engine and said rotating electric machine after the state of charge of said second battery becomes lower than the state of charge of said first battery.
