摘要： A charging signal Vi responding to a charging current is inputted to one input terminal (−) of an operational amplifier 95 forming a comparator and a setting signal Vr corresponding to a setting current value is inputted to the other input terminal (+) of the operational amplifier 95. When the charging signal Vi is not higher than the setting signal Vr, a charging stop signal is generated from the output terminal of the operational amplifier 95 to interrupt a switch unit 4. A starting signal Vcc larger than the setting signal Vr applied to the other input terminal (+) is applied to the one input terminal (−) of the operational amplifier 95 through a condenser 94 till a prescribed time elapses from the start of a charging operation to generate a charging start signal from the output terminal of the operational amplifier 95 and electrically conduct the switch unit 4.

摘要： To prevent a battery pack from being over-discharged even under a state that the battery pack (a secondary battery) is connected to a discharging device that is not connected to an ac input power source for a long time. A charging device has a pair of output lines and an anode terminal and a cathode terminal of a secondary battery electrically connected between the output lines to carry out a charging operation. In the charging device including a component circuit part electrically connected by traversing a part between the pair of output lines, a switching element is inserted between the component circuit part and one of the pair of output lines. When the charging device is not connected to an input power source, the switching element is allowed to be non-conductive to interrupt a discharging path so that the component circuit part does not form the discharging path.

摘要： A charging apparatus able to safely and reliably secure capacity is provided. The charging apparatus comprises: a charging current configuration unit that configures a set value for the charging current flowing to the battery; a charging current controller that controls the charging current on the basis of the set value configured by the charging current configuration unit; a cell voltage detector that detects the cell voltages applied to each cell; and a voltage determining unit that determines whether or not at least one of the cell voltages detected by the cell voltage detector has exceeded a threshold voltage. If it is determined by the voltage determining unit that at least one of the cell voltages has exceeded the threshold voltage, then the charging current configuration unit switches the set value to a smaller value.
