Abstract: A battery pack (30) is configured to couple to a power tool (10) by sliding in a sliding direction and it contains a plurality of cells (31). A pair of battery-side, electric-power terminals (312a, 312b, 314a, 314b) and a battery-side signal terminal (313) can be electrically connected to a pair of tool-side, power-supply terminals (212, 214) and a tool-side signal terminal (213), respectively, which are provided on the power tool (10). The pair of battery-side, electric-power terminals (312a, 312b, 314a, 314b) and the battery-side signal terminal (313) are disposed in parallel adjacently in a direction that intersects the sliding direction.

Abstract: In one aspect, the present disclosure discloses a charging system including a battery pack and a charger. The battery pack includes a first battery pack terminal, a second battery pack terminal, and a third battery pack terminal. The second battery pack terminal is spaced apart from the first battery pack terminal in an intersecting direction. The intersecting direction intersects a removal direction of the battery pack from the charger. The charger includes a first charger terminal, a second charger terminal, and a third charger terminal. The second battery pack terminal is arranged so as to pass through an area spaced apart from the third charger terminal in a process of removing the battery pack from the charger.

Abstract: A battery charger in one aspect of the present disclosure comprises a charging unit, a first voltage detector, a second voltage detector, and a determination unit. The determination unit determines that there is an abnormality in at least one of a charge path or a detection path when an absolute value of a difference between a voltage of a battery detected by the first voltage detector and a voltage of the battery detected by a second voltage detector is equal to or greater than a threshold value.

Abstract: A charger in one aspect of the present invention includes: a connecting portion, two protection devices, a charging device, a control device, and a voltage detection device. A first protection device is configured such that its power consumption in a charging inhibited state is lower than that in a charging permitted state. A second protection device is configured such that its power consumption in the permitted state is lower than that in the inhibited state. The control device is configured to respectively set, when the battery is not connected to the connecting portion, the first protection device to the inhibited state and the second protection device to the permitted state, and thereafter switch, when the voltage value of the charging path detected by the voltage detection device is equal to or greater than a predetermined specified voltage value, the second protection device to the inhibited state.
