A vehicular electric power system includes an electric generator (10), first and second batteries (20, 30), electrical loads (42) connected to the first battery, a switch (50) that selectively connects and disconnects the second battery to and from the generator and the first battery, a first controller (70) that controls the switch, a regulator (10a) that regulates the output voltage of the generator to a regulation voltage (Vreg), and a second controller (80). During operation of the generator in a regenerative mode, the second controller variably sets the regulation voltage and thereby controls the output voltage of the generator so as to keep the difference between a target output voltage and the detected output voltage of the first battery not greater than a predetermined allowed voltage deviation and keep the difference between the regulation voltage and the target output voltage of the first battery not greater than a predetermined threshold. |
