The invention relates to a method for operating an electric energy store (), to an electric energy store (), and to a device, having an electric energy storage module (), a switch unit (), and a first and second connection (). The method has the following steps which follow one another chronologically: in a first step, a signal of a sensor of the electric energy store () is evaluated; in a second step, a critical state of the electric energy store () is ascertained; in a third step, an electrically conductive connection between the electric energy storage module () and the first and second connection () is interrupted in the charge direction by means of the switch unit (), while simultaneously the electrically conductive connection between the electric energy storage module () and the first and second connection () remains connected in the discharge direction.

Method for operating an electric energy store, electric energy store, and device

A battery system () which comprises a metallic battery housing () and a metallic component housing (), wherein at least one battery module () having at least one battery cell () and a control unit () for controlling and monitoring the at least one battery module () are arranged in the battery housing () and wherein at least one electrical component () is arranged in the component housing (), which electrical component is electrically connected to the at least one battery module ().

Battery system

The invention relates to a battery module having a plurality of battery cells, in particular lithium ion battery cells, comprising a plurality of separating walls (), wherein a battery cell () is arranged between two separating walls () and a first compensating element () is arranged between a first battery cell () and a separating wall () adjacent to the first battery cell () and a second compensating element () is arranged between a second battery cell () and a separating wall () adjacent to the second battery cell (), characterized in that the first compensating element () and the second compensating element () have a different value () of a deformation constant.

Detection of corrosion within an at least partially electrically conductive housing of an electric energy storage unit. The electric energy storage unit has a positive terminal and a resistance element between the positive terminal and the housing. State of charge values of the electric energy storage unit for at least one first instant of time and at least one second instant of time are determined. An electrical isolation resistance value between the housing of the electric energy storage unit and at least one reference point for at least one third instant of time may also be determined. A first comparison of a difference of the determined state of charge values with a predefined state of charge difference value for the electric energy storage unit and/or a second comparison of the determined electrical isolation resistance value with a predefined electrical isolation resistance value for the electric energy storage unit are performed.
