    摘要: A charging device has a charging unit and a control unit. The charging unit charges a battery pack the battery pack being either a first type or a second type of battery pack. The first type of battery pack includes a single battery cell or a first plurality of battery cells connected in series. The second type of battery pack includes a single battery unit or a second plurality of battery units connected in series. Each battery unit includes at least two battery cells connected in parallel. The control unit controls the charging unit to control at least one of a charging current flowing through the battery pack and a charging voltage applied across the battery pack, depending on the battery pack to be charged.

    摘要: A motor has an output shaft which is rotatably supported by a housing, a rotor which is fixed to the output shaft and which comprises a printed-wiring board, and a stator which is fixed to the housing and which comprises a magnet facing the rotor. The printed-wiring board comprises a coil/commutator disk and a coil disk. A commutator conductor pattern is formed in a commutator region of the coil/commutator disk. Likewise, coil conductor patterns are formed in respective coil regions of the coil/commutator disk and of the coil disk.

    摘要: A charging device includes a battery voltage detecting circuit for detecting the voltage of a battery pack; and a microcomputer having RAM for temporarily storing a battery voltage detected by the battery voltage detecting circuit, and a CPU for calculating a battery voltage gradient from the battery voltage detected by the battery voltage detecting circuit and a battery voltage sampled a prescribed time earlier. The charging device determines that the life of the battery has expired when the voltage of the battery pack prior to charging is less than or equal to a prescribed value J and the battery voltage gradient within a prescribed time period after the start of charging is greater than or equal to a first prescribed value K. The charging device also includes a display circuit for notifying the user when the life of the battery pack has deteriorated.
