Abstract

Method for the detection of corrosion within an at least partially electrically conductive housing of an electric energy storage unit, the electric energy storage unit having a positive terminal and featuring a resistance element with a preassigned electrical resistance value between the positive terminal and the at least partially electrically conductive housing, where the method comprises the step of determining 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 and/or determining an electrical isolation resistance value between the housing of the electric energy storage unit and at least one reference point which is situated outside of the electric energy storage unit for at least one third instant of time and further comprises the step of performing 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 performing a second comparison of the determined electrical isolation resistance value with a predefined electrical isolation resistance value for the electric energy storage unit and further comprises the step of generating a signal concerning the detection of corrosion depending on the first comparison result and/or the second comparison result.
