The patent application (Publication Number: US20230400360A1) describes an electrical assembly with multi-zone temperature monitoring. The assembly includes a heat-generating electrical device, a measurement circuit with temperature-dependent electrical measuring resistors positioned in different temperature-measurement regions of the device, and an analysis device with a measurement channel for detecting measured values. The resistors are connected to the analysis device via a common measurement line, allowing the device to determine if a temperature or temperature limit is exceeded in any of the temperature-measurement regions by analyzing the signal on the measurement channel.

Furthermore, the patent application details the use of temperature-dependent electrical measuring resistors made, in part, from vanadium dioxide, integrated into the heat-generating electrical device. The analysis device is designed to detect temperature limits being exceeded by monitoring changes in current or voltage on the measurement channel. The measurement circuit is configured to set measurement thresholds that ensure accurate detection of temperature limits being exceeded in the different temperature-measurement regions. Additionally, the assembly can be used in various applications such as heating devices like warming blankets or cell connectors, providing efficient and reliable multi-zone temperature monitoring capabilities.
