Abstract

An energy storage unit, particularly for a motor vehicle, has an application unit that is configured to detect and/or process predetermined operating parameters of the energy storage unit. The energy storage unit further includes a safety unit that is configured to cryptologically process the detected and/or processed operating parameters. The energy storage unit also includes a communication interface for making the cryptologically processed operating parameters available.
