  • Publication number: 20120321919
    Abstract: A battery case includes a deformable lateral wall. The battery case is provided to receive at least one electrochemical energy storage device. An electrochemical energy storage device includes a cell frame, which partially surrounds the device and in some areas forms the outer wall of the battery case. The battery case also includes a case cover, by which at least one electrochemical energy storage device can be electrically contacted. A lateral wall forms at least in some areas the outer wall of said battery case, wherein the stiffness of said lateral wall is less than the stiffness of the cell frame. When there is a pressure difference between the inner space of the battery case and the environment around the battery case, the lateral wall is therefore deformed and the volume of the battery case increases. The lateral wall is connected at least in some areas to said cell frame in a gas-tight manner.
