Abstract

A method for determining a performance information, including a capacity information, of a battery of a motor vehicle on-board power network connected to a DC converter is disclosed. The DC converter is configured to impress at least one AC current with at least one predetermined frequency into the on-board power network. The capacity information is derived from at least one first electrical parameter at an output of the DC converter to the on-board power network and from at least one second electrical parameter that describes a reaction of the battery to the impressed AC current. A motor vehicle configured to perform the method is also disclosed.
