Abstract: This battery includes a battery module that is disposed inside a housing, includes a plurality of battery cells, and has a plurality of side surfaces oriented in different directions and a component that is electrically connected to the battery module, in which the battery module and the component are connected by a plurality of bus bars, and each of the plurality of bus bars are disposed on different side surfaces of the battery module and passes between the side surface on which the bus bars are disposed and the housing.

Abstract: This battery includes a cell and a cell holder having a plurality of housing portions for housing the cell, in which the housing portion has a bottom portion abutting one end of the cell and a wall surrounding a periphery of the cell, and the wall has a formed bulge that is continuous with the bottom portion and bulges to an inside of the housing portion to abut against a side wall of the cell.

Abstract: A battery pack has a temperature detection unit that detects the temperature of a battery cell. The temperature detection unit is provided with a first temperature sensor that is attached to a central battery cell disposed at the center in a first direction among a plurality of battery cells, and a second temperature sensor that is attached to an end battery cell disposed at one end in the first direction among the plurality of battery cells. No temperature sensor is attached to an end battery cell disposed at the other end in the first direction among the plurality of battery cells.

Abstract: A capacitor 1 which is provided so as to be installable in a first loading part C of a first electrical power device and a second loading part S103 of a second electrical power device S is configured to have an external shape such that a first abutment part which, upon loading of the capacitor into the first loading part, comes into abutment with the first loading part C differs from a second abutment part 26 which, upon loading of the capacitor into the second loading part S103, comes into abutment with the second loading part S103.

Abstract: A battery pack includes a core pack. The core pack includes a cell holder in which cells are held. The core pack is accommodated in a casing 18. A projection is provided on an inner wall of the casing, and projects towards an outer wall of the cell holder. The projection abuts the core pack.
