Various embodiments may include a control apparatus for an energy storage unit of a motor vehicle comprising: a non-volatile memory storing a first initial configuration for a first energy storage unit and a second initial configuration for a second energy storage unit. The memory is connected to a further memory having a first adaptation configuration for the first energy storage unit and a second adaptation configuration for the second energy storage unit. The non-volatile memory comprises a first memory part storing the first initial configuration and a second memory part electrically decoupled from the first memory part storing the second initial configuration.

Control apparatus for an energy storage unit

An on-board electrical system for a vehicle comprising: a first energy store; a second energy store; a DC/DC converter bidirectionally transferring energy between the first energy store and the second energy store; and two switching devices for coupling a first terminal of the second energy store to a first terminal of the first energy store via a first node, a second node, and a third node. The system further comprises: four current determining units for: a first current flowing between the first terminal of the first energy store and the first node, a second current flowing via the first switching device and the second switching device, a third current flowing between the first terminal of the second energy store and the second node, and a fourth current flowing between the third node and the DC/DC converter; an electrical resistor couplable to the first terminal of the second energy store by means of a third switching device; a voltage determining unit determining a first voltage value of the second energy store if the electrical resistor is electrically isolated from the first terminal of the second energy store and a second voltage value of the second energy store if the electrical resistor is electrically coupled to the first terminal of the second energy store; and an internal resistance determining unit for characterizing an internal resistance of the second energy store on the basis of determined first voltage and the second voltage and for classifying the determined resistance value on the basis of the determined first, second, third, and fourth current values.
