Abstract

A measuring arrangement, particularly for measuring the temperature of an accumulator cell, includes an object of measurement (10), a support element (14), and a temperature sensor (12) electrically connected with the support element (14). The temperature sensor (12) is mounted on the support element (14) and is thermally connected with the object of measurement (10). The invention relates further to an energy storage module with this type of measuring arrangement, as well as to an electrical apparatus with this type of energy storage module.
