In this white paper different possible definitions of State of Health (SoH) are discussed. In general, the SoH is a measure for the health of the battery. Depending on the application, the demands asked from the battery can vary. Does the health only involve the capacity that can be delivered or does it also take into account the internal resistance? We will also introduce some possible direct measurement approaches. Furthermore we will deal with how to communicate SoH in a clear and consistent way to the user.
