A vehicle power unit is operable to, when not driving the starter, charge first and second capacitors. A controller is operable to, when driving the starter, cause the battery to supply power to the starter if a total voltage of first and second capacitor voltages is smaller than a predetermined total voltage. The controller is operable to, when driving the starter, form a parallel circuit of the battery and the first capacitor, and connect the second capacitor in series to the parallel circuit if the total voltage is not smaller than the predetermined total voltage at a beginning of use of the vehicle. The controller is operable to, when driving the starter, disconnect the battery from the starter. The vehicle power unit reduces a load applied to the battery when driving the starter, accordingly extending a life time of the battery. |
