A vehicle electric power generation apparatus includes an electric power generator, a first electric power storage, a second electric power storage, a first voltage detector, a second voltage detector, and an electric power generation controller. The controller sets, as a first allowable voltage, an upper limit value of a terminal voltage of the first storage and sets, as a second allowable voltage, an upper limit value of a terminal voltage of the second storage, and raises, when the generator is to be controlled in a regenerative electric power generation state, a generated voltage derived from the generator higher than both of the first allowable voltage and the second allowable voltage. When the terminal voltage of the first storage reaches the first allowable voltage or the terminal voltage of the second storage reaches the second allowable voltage, the controller prevents the generated voltage of the generator from rising.
