A charging device includes a base and a platform that extends upward from the base. The base and platform may each be configured with wireless charging surfaces to enable wireless charging of a computing device upon contact. The base includes a recess in front of where the platform extends to provide support to a computing device, such as a smartphone. The base's surface may gradually rise until reaching the recess to provide further support to the smartphone and thereby prevent the smartphone from sliding down. The charging device includes female receptacles to enable charging adapters to connect to the charging device, thereby increasing the number of accessories charged with the charging device. Charging adapters can include a laterally extending platform on which, for example, a smartwatch can rest, or a charging shaft that includes a series of electrical contacts for charging external battery devices.

A power tool includes a housing, a battery coupled to the housing, and a battery cover which covers at least a portion of the battery. The battery cover includes an expandable portion. The expandable portion is moveable from a collapsed position to an expanded position. When the expandable portion is in the collapsed position, the battery cover has a first internal area. When the expandable portion is in the expanded position the battery cover has a second internal area. The first internal area is less than the second internal area.

A plurality of battery cells each having a positive electrode terminal and a negative electrode terminal; and a bus bar which connects the electrode terminals facing each other in the battery cells adjacently disposed among the plurality of battery cells.

In a stack, a plurality of power storage cells are stacked. A resin plate is placed on the stack. A flexible printed circuit board is placed on the resin plate and has an electric circuit electrically connected to the plurality of power storage cells. A thermistor element is provided on the electric circuit and is in contact with one power storage cell of the plurality of power storage cells to detect a temperature of the power storage cell. A cover member is provided on the resin plate to cover the flexible printed circuit board. An elastic body is located between the cover member and the thermistor element to press the thermistor element toward the power storage cell. The cover member includes a protuberance that protrudes toward the resin plate side. The elastic body is disposed on the protuberance.

A power storage module includes: a stack in which a plurality of power storage cells are stacked in a stacking direction; a resin plate placed on the stack of the plurality of power storage cells; a flexible printed circuit board placed on the resin plate and having an electric circuit electrically connected to the plurality of power storage cells; and a cover member provided on the resin plate so as to cover the flexible printed circuit board. The resin plate includes a projection that extends through the flexible printed circuit board. The cover member includes a tubular protrusion that protrudes toward the flexible printed circuit board on the resin plate. The projection is accommodated in an inner periphery of the tubular protrusion. The tubular protrusion is in abutment with the flexible printed circuit board at a position to avoid the electric circuit.

A battery pack includes cell units in which upper and lower battery cells are connected in series, wherein an output of series-connection and an output of parallel-connection can be switched. The cell units are respectively provided with protection circuit ICs for monitoring the state of the battery cells, and only the protection circuit on the lower cell unit side is provided with a controller 350 including a microcomputer. To adjust the power consumption for the microcomputer only provided in the lower cell unit, the circuit on the upper cell unit side is provided with a current consumption control means including dummy loads. The current consumption control means is operated in conjunction with the start-up of the microcomputer in the controller so as to equalize power consumption on the upper cell unit side and the lower cell unit side.
