Abstract: In a method and device for measuring current at a converter, the prevailing phase current is determined at the output of the converter by current-measuring devices, in order to supply it to a closed-loop control device assigned to the converter. The prevailing phase current to be ascertained at an output of the converter is measured independently at two current-measuring devices, and the measuring results of both current-measuring devices are utilized to determine the prevailing phase current.

Abstract: A position-measuring device includes a first assembly and a second assembly. The first assembly, installable on a first object, has a profiled element that bears a scale having a first and second measuring graduation. The second assembly, installable on a second object, has a first scanning unit that is movable along a travel path in a measuring direction to scan the first measuring graduation. A position of the first object relative to the second object is therefore measurable. A second scanning unit is mounted on the profiled element so as to enable the second measuring graduation to be scanned, and is positioned in a way that allows the first scanning unit to traverse collision-free along the travel path at a distance spaced apart from the second scanning unit orthogonally to the measuring direction such that a displacement of the scale relative to the first object is measurable.

Abstract: An energy storage unit for a motor vehicle battery is provided, having an energy store, particularly configured as a battery cell module, for storing and delivering electric power. A measuring device measures electrical properties of the energy store. An evaluation unit, connected to the measuring device, ascertains the operational status of the energy store from the measurement results of the measuring device. An indicator unit is connected to the evaluation unit for depicting the operational status of the energy store. By ascertaining and depicting the operational status and not just the state of charge of the energy store, it is possible to dispense with separate complex measurements when fitting the energy store, so that an energy storage unit can be checked quickly and efficiently when fitted into a motor vehicle.
