Abstract

A receptacle device for at least one electrode assembly includes a metal housing and a metal. The housing and the cover each are a prismatic shape with a base surface, side walls and an aperture. The aperture lies opposite the base surface. The base surface of the cover is at least one wall thickness of the side walls of the cover larger than the base surface of the housing. The receptacle device further includes a measuring device configured to measure at least one measurement variable. The measuring device is arranged on an edge of the aperture of the housing or of the cover. The measurement variable is a value for at least one of a voltage, a current strength, and a temperature.

First claim

1 . A receptacle device for at least one electrode assembly, comprising:
a metal housing and a metal cover, the housing and the cover each being a prismatic shape with a base surface, side walls and an aperture opposite the base surface; and a measuring device configured to measure at least one measurement variable, wherein the base surface of the cover is at least one wall thickness of the side walls of the cover larger than the base surface of the housing, wherein the measuring device is arranged on an edge of the aperture of the housing or of the cover, and wherein the measurement variable is a value for at least one of a voltage, a current strength, and a temperature.

2 . The receptacle device as claimed in claim 1 , wherein cutouts are arranged on the edge of both sides of the measuring device and the terminals of the electrode assembly can are configured to be guided outwards through said cutouts.

3 . The receptacle device as claimed in claim 2 , wherein an electrical insulation is arranged in the cutouts, said electrical insulation configured to insulate in an electrical manner the terminals from at least one of the housing and the cover, said terminals being guided outwards through the cutouts.

4 . A battery comprising:
at least one electrode assembly in a receptacle device, the receptacle device including: a metal housing and a metal cover, the housing and the cover each being a prismatic shape with a base surface, side walls and an aperture opposite the base surface; and a measuring device configured to measure at least one measurement variable, wherein the base surface of the cover is at least one wall thickness of the side walls of the cover larger than the base surface of the housing, wherein the measuring device is arranged on an edge of the aperture of the housing or of the cover, wherein the measurement variable is a value for at least one of a voltage, a current strength, and a temperature, and wherein the housing is sealed using the cover and terminals of the electrode assembly are guided outwards in an insulated manner between the cover and the housing.

5 . The battery as claimed in claim 4 , wherein the electrode assembly is an electrode stack and each electrode of the electrode assembly comprises a flap strip and in each case the flap strip of the electrodes that have the same polarity are connected to a terminal.

6 . The battery as claimed in claim 4 , wherein the electrode assembly is packaged in a multi-layer packaging film.

7 . The battery as claimed in claim 4 , wherein the housing is connected to the cover using a laser welding method or using Nano Molding Technology “NMT”.

8 . The battery as claimed in claim 4 , wherein the seal further includes a sealing flange having at least one of solid metal glass and a metal alloy.

9 . The battery as claimed in claim 4 , wherein the seal further includes a paste, the paste being a ceramic paste or a glass paste.

10 . A motor vehicle comprising:
at least one battery including:
at least one electrode assembly in a receptacle device, the receptacle device having:
a metal housing and a metal cover, the housing and the cover each being a prismatic shape with a base surface, side walls and an aperture opposite the base surface; and
a measuring device configured to measure at least one measurement variable,
wherein the base surface of the cover is at least one wall thickness of the side walls of the cover larger than the base surface of the housing,
wherein the measuring device is arranged on an edge of the aperture of the housing or of the cover,
wherein the measurement variable is a value for at least one of a voltage, a current strength, and a temperature, and
wherein the housing is sealed using the cover and terminals of the electrode assembly are guided outwards in an insulated manner between the cover and the housing.
