In a battery apparatus, a first precharge switch is connected between a terminal of a first battery pack and a capacitor of an external apparatus, and a second precharge switch is connected between a terminal of a second battery pack and the capacitor. A first precharge control circuit controls an operation of the first precharge switch based on a difference between a voltage of the first battery pack and a voltage of the capacitor, and a second precharge control circuit controls an operation of the second precharge switch based on a difference between a voltage of the second battery pack and the voltage of the capacitor. A processor transfers a first control signal for controlling the first precharge switch to the first precharge control circuit, and transfers a second control signal for controlling the second precharge switch to the second precharge control circuit.
