摘要： In a charging device, a driving power supply circuit for driving a control circuit is formed as a separate system from a first power supply circuit, regardless of whether the first power supply circuit is in a driving state or a non-driving state. A microcomputer alternately and intermittently controls the first power supply circuit in the driving state or the non-driving state when the battery pack is not mounted in the charging device in order to reduce the potential difference between the battery pack and the output voltage of the first power supply circuit, thereby avoiding an excessive discharge current from the battery pack when the battery pack is mounted in the charging device.

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 battery charger for charging a lithium-ion battery includes a temperature control unit and a current supplying unit. The temperature control unit controls a temperature of the lithium-ion battery to fall in a predetermined range. The predetermined range is divided into a plurality of sub-divided temperature ranges. The current supplying unit supplies the lithium-ion battery with a temperature-dependent current relation to a sub-divided temperature range in which the temperature of the lithium-ion battery falls.

摘要： To reduce power consumption when charging a secondary battery is not performed, a first power supply circuit is disabled but a second power supply circuit is enabled when the secondary battery is unloaded from a battery charger. Both the first and second power supply circuits are enabled when the battery is loaded in the charger The first power supply circuit is provided for supplying power to the secondary battery. The second power supply circuit is provided for supplying a first voltage to such components that are operated with the first voltage and a second voltage to such components that are operated with the second voltage, wherein the second voltage is greater than the first voltage. When the battery is unloaded from the charger, the second power supply circuit supplies only the first voltage whereas when the battery is loaded in the charger, the second power supply circuit supplies the first and second voltages to the corresponding components.
