Abstract: A battery device for powering a working device. The battery device including a locking component configured to be capable of extending out of a housing of the battery device or retracting into the housing to engage with or disengage from the working device. The battery device further including an operation component configured to be capable of being actuated by an operator. The battery device further including a transmission mechanism configured to transmit a motion of the operation component to the locking component when the operation component is actuated so as to make the locking component disengage from the working device. Wherein the transmission mechanism includes at least two connecting rods which are sequentially overlapped in a force transmission direction.

Abstract: A collector plate assembly includes a collector plate and a collector plate support, the collector plate having a welding part for welding to a terminal of a battery unit, and the collector plate being installed in the collector plate support in such a way that the welding part is exposed by the collector plate support. A battery pack includes a housing; a battery support, enclosed by the housing and supported in the housing, the battery support being electrically connectable to an electric tool to supply electric power to the electric tool; and a collector plate assembly including a collector plate support and a collector plate installed in the collector plate support.

Abstract: A battery pack including a housing; and two or more battery cells located in the housing. The two or more battery cells interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector contains a plurality of first electrical terminals connected to the two or more battery cells, and a terminal holder adapted to be removably connected to the plurality of the first electrical terminals. The terminal holder is adapted to be installed to the housing in a first orientation at which the two or more battery cells are electrically connected, or in a second orientation at which the two or more battery cells are not electrically connected. The terminal holder contains a plurality of second electrical terminals.

Abstract: A battery pack containing a frame; and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a configurable connector which is configured to enable electrical connections between the two or more battery cells. The configurable connector is adapted to be configured in a first status or a second status. In the first status, the two or more battery cells are electrically connected, and in the second status, the two or more battery cells are not electrically connected. The battery pack is not fully operational without the terminal holder inserted, therefore before it is delivered to the end user the energy loss due to self-discharging during storage and shipping can be minimized.

Abstract: There is provided battery cell assembly for a power tool battery pack. The battery cell assembly comprises a cell housing, a battery cell and a cell strap. The battery cell define a pole and is supported by the cell housing. The cell strap comprises a leg for electrically contacting the pole. The cell housing defines a first formation and the cell strap defines a second formation configured to engage the first formation so as to align the leg with the pole.

Abstract: A battery pack (20), which includes: a housing; a frame disposed inside the housing; and two or more cells (32) mounted to the frame. The two or more cells (32) are connected with each other through a configurable connector (52). The configurable connector (52) is suitable to connect or disconnect an electrical connection between the two or more cells (32). Wherein the configurable connector (52) includes a user contactable switch (22) located on an outer surface (21) of the housing. The user contactable switch (22) is configured to move within a plane parallel to the outer surface (21), such that the contactable connector (52) is switched between a first state and a second state. In the first state, the electrical connection exists between the two or more cells (32); in the second state, the electrical connection does not exist between the two or more cells (32).

Abstract: A battery pack comprising a frame and two or more battery cells installed to the frame. The two or more battery cells are interconnected by a rotatable connector which is configured to enable electrical connections between the two or more battery cells. The rotatable connector is adapted to be switched between at least a first rotational position in which the two or more battery cells being electrically connected, and a second rotational position, in which the two or more battery cells being not electrically connected.
