Abstract: A battery device includes: a storage unit that stores battery information including a closed circuit voltage of a plurality of battery cells electrically connected to each other and a change amount in the closed circuit voltage; a setting unit that sets an acquisition range of the closed circuit voltage based on the battery information; a detection unit that detects the closed circuit voltage; and a conversion unit that converts the closed circuit voltage detected by the detection unit into a digital signal within the acquisition range set by the setting unit.

Abstract: A control apparatus for a vehicle determines whether to perform either of a first control and a second control. In the first control, power is transferred between a power supply facility outside a vehicle and a power storage apparatus during stopping of the vehicle. In the second control, power is transferred between a rotating electric machine and the power storage apparatus through an inverter during traveling of the vehicle. In response to the first control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a first limit value. In response to the second control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a second limit value. The apparatus sets at least either of the first and second limit values to a value suppressing decrease in drivability of the vehicle.
