摘要： A secondary battery module includes a plurality of battery blocks each obtained by stacking a plurality of battery cells. The secondary battery module includes a holding member adapted to hold the plurality of battery blocks and including a pair of opposed end plates, a pair of opposed side plates, and a section plate arranged between the adjacent battery blocks to partition the battery blocks; and an inter-block bus bar provided across the section plate and adapted to electrically connect the adjacent battery blocks. The inter-block bus bar has a fuse portion.

摘要： An assembled battery including a plurality of batteries each including a container which houses a charge/discharge body, an electrode terminal on one surface of the container, a sealing member which is provided between the container and the electrode terminal sealing between the container and the electrode terminal, and a busbar joined to each of the electrode terminals of the batteries that differ from each other. Each of the electrode terminals includes an electrode terminal protruding section extending in a direction of separation from the one surface. The busbar includes a busbar hole for the electrode terminal protruding section to be fitted. The electrode terminal protruding section and the busbar hole fit to each other and abut on each other. A coupling section between an outer surface of the electrode terminal protruding section and an inner surface of the busbar hole is at least partially welded.
