A temperature adjustment structure adjusts the temperature of an electricity storage apparatus ( 10 ) in which a plurality of electricity storage elements ( 11 ) are juxtaposed in a predetermined direction (direction X), and has a first passageway and a second passageway that cause a temperature-adjusting gas to pass through different regions (a first region and a second region) in the electricity storage apparatus. The first passageway ( 21 a, 21 b ) causes the temperature-adjusting gas to pass a space between the electricity storage elements ( 11 ), which are adjacent to each other in the predetermined direction in the first region. The second passageway ( 21 c, 21 d ) causes the gas having passed through the first region to pass, in a direction that is different from the flowing direction of the gas within the first region, the space between electricity storage elements in the second region which are adjacent to each other in the predetermined direction.

A system for an electronic device includes a housing having one or more walls that define an internal region. An outlet port is fluidically coupled to the internal region of the housing, which allows emission of a fluid from the internal region of the housing as a first flow at a first temperature. A merging element, fluidically coupled to the outlet port, merges the first flow with a second flow, which has a second temperature that is less than the first temperature.

A simplified control scheme is presented for use in a power tool. The power tool may be comprised of two or more lithium-ion battery cells connected in series and operable to drive the motor in the tool. A charging circuit is configured to receive a charging current from an AC adapter and to supply the charging current to the battery cells. A microcontroller monitors the voltage of the battery cells and terminates charging of the battery cells in accordance with the monitored voltages of the battery cells. The microcontroller does not receive power from the battery cells but is only powered by the AC adapter. Of note, each of the battery cells preferably employs an electrolyte composition comprised of a redox shuttle material. In combination with other tool components, the use of the redox shuttle material reduces or eliminates the need for expensive charge and discharge controls, thereby reducing the cost of the tool.
