    摘要： A vehicle battery system includes: a first storage battery supplying electric power to a starter; a second storage battery connected in parallel with the first storage battery and including an internal switching unit switching a connection state with the first storage battery; an alternator connected to the first and second storage batteries and driven by an engine so as to generate electric power; a charging state detection unit detecting a charging state of the second storage battery: a charging control unit controlling a power generating state of the alternator and a switching state of the internal switching unit based on a detection result of the charging state detection unit; and a power generation margin determination unit determining whether there is a margin in the power generation of the alternator or not. When the charging state detection unit detects that a charging rate of the second storage battery is not higher than a minimum threshold, and the power generation margin determination unit determines that there is no margin in the power generation, the charging control unit controls the internal switching unit into an open state.

    摘要： A control device for a vehicle includes: a motor generator mechanically connected to an output shaft of an engine; a main battery electrically connected to the motor generator; a sub battery electrically connected to an electric load of the vehicle; and a relay adapted to switch whether the batteries are to be electrically connected or not by turning the relay on or off. The relay is turned off during a powering operation of the motor generator, and the relay is turned on during a regenerative operation of the motor generator. It is determined that the relay is off-fixed in a case where a voltage of the second battery is a predetermined voltage or lower or a charge current of the second battery is a predetermined current or smaller in a state that a command to turn on the relay is outputted during the regenerative operation of the motor generator.
