Method for determining a status information, energy storage arrangement and motor vehicle describing the state of charge and / or the performance of a first energy storage device

摘要

Method for determining a state of charge and / or the performance of a first electrical energy storage device (7), which first electrical energy storage device (7) is part of a motor vehicle side comprising a first electrical energy storage device (7) and a second electrical energy storage device (8) connected in series therewith Energy storage arrangement (1) forms, descriptive state information, comprising the steps: - introducing a defined amount of electrical energy from the second electrical energy storage device (8) in the first electrical energy storage device (7), - determining at least one depending on the introduced amount of electrical energy variable state parameter of the first electrical energy storage device (7), - Determining the state information based on the at least one determined state parameter.
