Battery module and battery pack including the same

摘要

A battery module and battery pack, the battery module including a pair of end plates facing each other; a plurality of battery units arranged in a first direction between the end plates; a first side plate extending along a first side of the plurality of battery units, the first side plate being coupled to the end plates; a second side plate extending along a second side of the plurality of battery units, the second side plate being coupled to the end plates and being disposed opposite to the first side plate; a first coupling member, the first coupling member coupling the end plates to the first side plate; and a second coupling member, the second coupling member coupling the end plates to the second side plate, wherein the first coupling member and the second coupling member are disposed in asymmetrical positions with respect to a central line of the end plates.

1. A battery module, comprising:
a pair of end plates facing each other; a plurality of battery units arranged in a first direction between the end plates; at least one first restraint member extending along a first side of the plurality of battery units, the at least one first restraint member being coupled to the end plates; at least one second restraint member extending along a second side of the plurality of battery units, the at least one second restraint member being coupled to the end plates and being disposed opposite to the first restraint member; a first coupling structure, the first coupling structure coupling one of the end plates to the at least one first restraint member; a second coupling structure, the second coupling structure coupling the one end plate to the at least one second restraint member, wherein the first coupling structure is asymmetrical with respect to the second coupling structure about a central line of the one end plate such that the first coupling structure couples the one end plate to the at least one first restraint member at a first height from a bottom of the one end plate and the second coupling structure couples the one end plate to the at least one second restraint member at a second height from a bottom of the one end plate, wherein the second height is different from the first height, and wherein the central line extends in a plane of the one end plate and is equidistant from the first restraint member and the second restraint member, and wherein a first lateral edge of the one end plate that is coupled with the first restraint member is free of any coupling structure at the second height.
