摘要： Provided is a control apparatus that controls a battery circuit, including a voltage detector that detects a battery voltage, a battery protection circuit that stops charging current when the battery voltage detected by the voltage detecting unit exceeds a protection voltage, and a charging circuit being capable of changing a charging current value for charging a battery. The control apparatus includes an input interface that reads the battery voltage detected by the voltage detecting unit, a decision unit that decides whether or not the read battery voltage has approached the protection voltage to a predetermined limit value, an output interface that outputs a signal for controlling the charging current, and a current control unit that limits the charging current to a predetermined limit value via the output interface when the read battery voltage is decided to have approached the protection voltage to the predetermined limit value.
