An electrical storage battery includes a housing and a plurality of rectangular cell assembly modules electrically coupled together. The rectangular cell assembly modules are mounted by spring damping elements in the housing and are in each case arranged in an intermediate space between an outer area of at least one lower edge of the cell assembly modules and the housing, with at least one common spring damping element extending transversely with respect to the direction of the longest side of the cell assembly modules along the plurality of cell assembly modules.

Electrical storage battery having spring damping element

A rechargeable battery includes a housing having a housing wall, at least one cell in the housing, and a contact element electrically connected to the at least one cell. The rechargeable battery also includes a plastic sealing element extrusion-coated on the contact element. The sealing element includes a supporting surface which lies flat against the housing wall at an interface. The supporting surface is transmission laser-welded to the housing wall at the interface. One of the supporting surface and the housing wall is at least partially transparent for the laser beam and the other of the supporting surface and the housing wall is absorbent for the laser beam.

Battery having sealed contact terminal bushing

A method for producing a prismatic rechargeable battery that includes providing a battery housing comprising a plurality of cell vessels separated by intermediate walls. The method also includes providing contact connector plates on opposite sides of each of the intermediate walls and electrically coupling the contact connector plates provided on opposite sides of the intermediate walls to each other through their associated intermediate walls. The method further includes arranging plate stacks in the cell vessels, each of the plate stacks having a plurality of contacts and coupling the electrical contacts of the plate stacks to contact connector plates provided on the intermediate walls. The method further includes closing the housing such that the cell vessels and the housing are sealed.

Prismatic rechargeable battery and method for producing such a battery

A prismatic rechargeable battery includes a housing comprising a plurality of cell vessels separated from one another by electrically insulating intermediate walls and a plate stack provided in each of the cell vessels, the plate stack comprising stacked electrode plates and a plurality of contacts. The battery also includes contact connector plates coupled to each of the intermediate walls such that each of the contact connector plates is in electrical contact with a contact of a plate stack. Each of the intermediate walls has a contact connector plate on a first side thereof electrically coupled to a contact connector plate on a second side thereof through the intermediate wall.
