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 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.

Abstract: A charging system in one aspect of the present disclosure includes a battery pack and a charger. The battery pack includes a battery and an information output circuit. The information output circuit outputs faulty state information in response to receiving a faulty state information request. The faulty state information indicates that the battery pack is in a first faulty state. The charger includes a charging power generation circuit, a charging control circuit, and a reception circuit. The charging control circuit transmits the faulty state information request. The reception circuit receives the faulty state information.
