Energy management control unit and method for determining a characteristic of an electrochemical energy storage device

摘要

An energy management control device for a means of locomotion (10) and a method for determining a characteristic of an electrochemical energy store (1) for supplying a vehicle electrical system of a means of transportation (10) are proposed. The following steps are carried out according to the invention: determining (100) a predefined operating state (II) of the vehicle electrical system, measuring (200) a voltage of the electrochemical energy store (1) during the predefined operating state (II), and - determining (300) the characteristic of the electrochemical energy store (1) on the basis of the determined voltage and a reference assigned to the predefined operating state (II), the predefined operating state (II) starting after actuation of an access function, but preferably before starting (IV) an internal combustion engine (4) of the Means of transport (10) ends.
