Abstract
Official abstract text for this publication.
In a support member, m×n (n is an integer equal to or larger than 4) cylindrical storage battery cells are arranged in a trefoil formation structure comprised of m (m is an integer equal to or larger than 4) tiers along a first direction. Along a second direction in the support member, n storage battery cells are arranged in a first tier, n+1 storage battery cells are arranged in a second tier, n storage battery cells are arranged in an m−1th tier, and n−1 storage battery cells are arranged in a m-th tier. The n storage battery cells in the first tier are arranged inward of the n+1 storage battery cells in the second tier in the second direction, and the n−1 storage battery cells in the m-th tier are arranged inward of the n storage battery cells in the m-lth tier in the second direction.
First claim
Opening claim text (preview).
1 . A support member for arranging m×n (n is an integer equal to or larger than 4) cylindrical batteries in a trefoil formation structure comprised of m (m is an integer equal to or larger than 4) tiers along a first direction, wherein along a second direction that intersects the first direction, n batteries are arranged in a first tier, n+1 batteries are arranged in a second tier, n batteries are arranged in an m−1th tier, and n−1 batteries are arranged in a m-th tier, the n batteries in the first tier are arranged inward of the n+1 batteries in the second tier in the second direction, and the n−1 batteries in the m-th tier are arranged inward of the n batteries in the m−1th tier in the second direction. 2 . The support member according to claim 1 , wherein in the case m is an integer equal to or larger than 5 n batteries are arranged in a third through an m−2th tiers. 3 . A battery module comprising: a plurality of storage battery cells; an inner case that houses the plurality of storage battery cells; and an outer case that houses the inner case, wherein each of the plurality of storage battery cells has a cylindrical shape, the inner case includes a support member for arranging m×n (n is an integer equal to or larger than 4) storage battery cells in a trefoil formation structure comprised of m (m is an integer equal to or larger than 4) tiers along a first direction, and in the support member, along a second direction that intersects the first direction, n storage battery cells are arranged in a first tier, n+1 storage battery cells are arranged in a second tier, n storage battery cells are arranged in an m−1th tier, and n−1 storage battery cells are arranged in a m-th tier, the n storage battery cells in the first tier are arranged inward of the n+1 storage battery cells in the second tier in the second direction, and the n−1 storage battery cells in the m-th tier are arranged inward of the n storage battery cells in the m−1th tier in the second direction. 4 . The storage battery module according to claim 3 , wherein the outer case includes a handle provided at one end of the trefoil formation structure of the storage battery cells stacked in the m tiers.
