摘要： A charging device includes a charging unit, a detecting unit, a determining unit, a current generating unit, an adjusting unit, and a display unit. The charging unit charges a battery. The detecting unit detects a voltage developed across the battery. The determining unit determines a charging state of the battery based on the voltage. The current generating unit generates a current. The adjusting unit adjusts the current based on the charging state. The display unit emits a first light having a first color and a first intensity in response to the current supplied thereto. The first intensity changes in accordance with changing of the current.

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.
