Automotive temperature monitoring device for industrial and energy storage applications

Mouser now offers the TTape distributed temperature monitoring device (DTMD) from Littelfuse. The device is a state-of-the-art platform tailored for Li-ion battery packs found in automotive, consumer, EV/HEV, industrial, and energy storage and harvesting applications.

The device is engineered to detect the slightest temperature variations across battery cells by supplying real-time data to prevent potential thermal runaways, fires or explosions. It is designed to detect these hotspots early, facilitating timely intervention.

The device offers over-temperature monitoring for multiple cells or large areas with a singular MCU input that can trigger the MCU to exit sleep mode during over-temperature events. It is also compatible with existing BMSs that use NTC thermistors, ensuring a seamless integration process without extensive modifications. With a single device, multiple cells can be monitored, therefore alerting the BMS sooner in case of overtemperature scenarios. The device does not need calibration or temperature look-up tables and comes with a pressure-sensitive adhesive for simple and quick installation. And, with a response time of less than one second, it ensures quicker alerts, signalling the potential onset of thermal runaway conditions.
