摘要:
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.

A battery holding unit (2) for accepting at least one electrochemical cell (3) comprises a support surface (4) for supporting an electrochemical cell (3) and a contacting unit (6) that has a contact surface (8). The contact surface can be made to rest against a current collector (9) of the electrochemical cell (3), and the contacting unit includes at least one contacting rail (7) on which the contact surface (8) is arranged.
摘要:
Disclosed is a frame for a galvanic cell consisting of an electrode stack that has a foil-type package, out of which at least two current collectors are brought. Said frame is designed so as to be able to be fixedly connected to the package of the cell when the cell is produced. When producing such a galvanic cell, a frame is fixedly connected to the package as the package is sealed.
摘要:
A charging apparatus for electric energy stores includes a holding device configured to accommodate one or a plurality of electric energy stores, or rechargeable electric energy stores for vehicles, a charging and charge control device configured to charge, in a controlled manner, the electric energy store(s) accommodated in the holding device, and an air-conditioning device configured to control the temperature inside the holding device. The air-conditioning device is further configured to adjust the air inside the holding device to the surrounding conditions with respect to the dew point.
