Abstract: A charger (40; 240; 340) charges a battery pack (20) that is detachably attachable to a cordless power tool (12). The charger has at least a first side wall (44b) that at least partially defines a battery pack receiving hole (44; 244) shaped to receive and accommodate the battery pack. A charging output element (62; 362) supplies charging power to the battery pack. The battery pack receiving hole has a lateral cross sectional area that decreases downwardly in the vertical direction of the battery pack receiving hole such that gravity causes the battery pack to be guided to a prescribed position within the battery pack receiving hole. In addition, the charging output element is positioned so as to be proximal to a corresponding charging power input element of the battery pack when the battery pack is disposed in the prescribed position.
Abstract translation: 充电器（40; 240; 340）对可拆卸地附接到无绳电动工具（12）的电池组（20）充电。 充电器至少具有至少部分地限定形状以接收和容纳电池组的电池组接收孔（44; 244）的第一侧壁（44b）。 充电输出元件（62; 362）向电池组提供充电电力。 电池组接收孔具有在电池组接收孔的垂直方向上向下减小的横向横截面积，使得重力使得电池组被引导到电池组接收孔内的规定位置。 此外，当电池组被布置在规定位置时，充电输出元件被定位成靠近电池组的相应的充电电力输入元件。

Abstract: A power tool system includes a hand-held power tool having a housing with a battery pack interface, an electrically-driven device and a first connector. A battery pack is detachably attached to the battery pack interface and supplies current to the electrically-driven device. An adapter has a second connector physically and electrically connected with the first connector in a detachable manner. The adapter receives power from the battery pack via the hand-held power tool and provides at least one additional electrical function to the hand-held power tool or performs at least one additional electrical function that the hand-held power tool is not otherwise capable of performing. Further, the adapter is at least partially disposed in a space defined in part by the housing and in part by the battery pack when the housing and battery pack are attached to each other.

Abstract: A power tool includes a motor and a controller in a power tool housing. A battery pack interface is defined on and/or in the power tool housing. A receptacle is defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing. At least one communication terminal is disposed within the receptacle and is electrically connectable to the wireless communication adapter. The controller outputs to the at least one communication terminal a signal indicating a charge level of a battery pack attached to the battery pack interface, a number of hours of operation of the power tool, a power tool overheated alert, and/or a battery pack overloaded alert.
