Abstract: To provide a battery connecting body and a power supply device capable of maintaining a state where a cover portion covers a connecting member. A bus bar module includes a plurality of bus bars that each connects electrodes of adjacent ones of a plurality of batteries arranged such that the electrodes thereof are arranged on a straight line to electrically connect the plurality of batteries in series and a casing that houses the plurality of bus bars. The casing includes a plurality of bus bar housing portions that each house each of the bus bars and the cover portions that each cover an opening of each of the bus bar housing portions, and the cover portions are each retained by the bus bar.

Abstract: A conductor, a current measurement device that measures current flowing through a current measurement target part of the conductor and outputs an output signal related to the current, and a casing that accommodates the conductor and the current measurement device are included, and the current measurement device includes a magnetic sensor that measures the current, a substrate that outputs the output signal based on an input signal input from the magnetic sensor, and a magnetic shield member in which the magnetic sensors, the substrate, and the current measurement target part are disposed, the magnetic shield member shielding magnetism between inside and outside of the magnetic shield member, and the casing includes a sensor accommodation chamber that accommodates the magnetic sensor and the substrate, a shield insertion port into which the magnetic shield member is inserted, and shield holding chambers holding the magnetic shield member at an accommodation position.

Abstract: A battery module includes laminated bus bars and which connect respective battery packs. Each of the laminated bus bars includes a plurality of bus bars formed in an identical shape. Each of the bus bars includes connecting portions which are formed at both ends in a first direction and electrically connect the battery packs and a deformation allowing portion which is formed between the connecting portions and is curved in a plate thickness direction as viewed in a second direction. The laminated bus bars are formed by laminating the bus bars such that the deformation allowing portions overlap with each other in the plate thickness direction and the connecting portions of the bus bars adjacent to each other are in contact with each other.

Abstract: The bus bar module includes: bus bars for connecting the batteries in series by connecting the positive electrode and the negative electrode of the adjacent batteries; a plurality of terminals electrically connected to the electrodes of the batteries; and a case for housing the bus bars and the terminals. Each terminal includes: a terminal main body on which an insertion hole is provided for inserting the electrode of the battery; and a projecting section projecting from a part of a peripheral edge of the terminal main body in a surface extending direction of the terminal main body. The terminal is arranged so that a projecting direction of the projecting section is along an arranging direction of the batteries.
