Abstract
An apparatus for measuring the voltage of a plurality of voltage sources mounted in a stack includes a plurality of contact units, each having a plurality of electrical contacts mounted therein, for voltage tapping of the voltage sources. The contact units are held in a support module, arranged side by side along a longitudinal axis. An evaluation unit is coupled in communication with the contacts contained in the contact units, either directly, or via an intermediate unit that includes addressing and processing capability. The number of contact units that are arranged in the support module is variable in accordance with the number of voltage sources contained in the stack, and the contact units themselves are movable longitudinally within the support module to accommodate spacing of the voltage sources in the stack.
