Patent ID: 10809133

Abstract:
The invention describes a calorimetric measurement set-up having a sensor unit (1) for controlling the quality of the operation of a battery having a cathode and an anode, wherein the measurement set-up or the sensor unit (1) is connected to data processing electronics (11) via a communication link (12) and sensor measured values are therefore recorded and processed. This measurement set-up is intended to achieve reproducible and sufficiently accurate quality control of a battery. This is achieved by virtue of the fact that the sensor unit (1) comprises at least one heat flow sensor (2), the sensor side of which can be fastened in a non-detachable manner with a material bond such that it rests directly on a battery contact of the cathode and/or the anode in the transverse direction, wherein a heat sink is fastened in a thermally conductive manner to the heat flow sensor (2) opposite the sensor side in a non-detachable manner and heat flow sensor signals at the battery contact of the battery can be read and processed further by the data processing electronics (11).
