Abstract
A rechargeable energy storage system includes a plurality of battery cells and a wall structure disposed adjacent to the plurality of battery cells and having an inner layer and an outer layer. An interior reinforcement structure includes a first sheet metal member and a second sheet metal member each having a plurality of vertical sections and a plurality of horizontal sections. The first and second sheet metal members define an aligned load transfer section wherein one of the plurality of horizontal sections of the first sheet metal member is vertically aligned with one of the plurality of horizontal sections of the second sheet metal member. The first and second sheet metal members define a crush region wherein one of the plurality of horizontal sections of the first sheet metal member is vertically misaligned with all of the plurality of horizontal sections of the second sheet metal member.
