Patent ID: 8728649

Claim:
A battery system comprising: a housing having opposite first and second side walls and opposite first and second end walls extending between the first and second side walls; a plurality of cells disposed in the housing, each of the cells having two opposite side surfaces aligned parallel to the side walls of the housing and opposite longitudinal end surfaces facing the end walls of the housing; side temperature-equalizing elements disposed adjacent each of the two opposite side surfaces of each of the cells to define an alternating arrangement of the side temperature-equalizing elements and the cells, so that each of the side surfaces of each of the cells has one of the side temperature-equalizing elements adjacent thereto, first and second end temperature-equalizing elements extending along inner surfaces of the respective first and second end walls and adjacent the longitudinal end surfaces of the individual cells, the temperature-equalizing elements being corrugated boards with two cover layers, at least one corrugation being arranged between the cover layers so that a cooling or heating medium can pass through a space between the cover layers; and an elastic panel between an inner surface of the first side walls of the housing and an adjacent one of the side temperature-equalizing elements, the elastic panel transmitting surface pressure to the alternating arrangement of individual cells and the corrugated boards defining the side temperature-equalizing elements, and wherein the temperature-equalizing elements provide mechanical dampening and impact cushioning for protecting the cells in a crash.
