TTape is ideally suited for a wide range of applications, including automotive EV/HEVs, commercial vehicles, and Energy Storage Systems (ESS). Its distributed temperature monitoring capabilities enable superior detection of localised cell overheating, thereby improving battery life and enhancing the safety of battery installations.

TTape’s key benefits and differentiators include:

• Premature cell ageing management: TTape aids vehicle systems in manageing premature cell ageing, significantly reducing the risks associated with thermal runaway.
• Extended battery pack life: TTape ensures that the battery pack remains serviceable for an extended period by initiating temperature management at an earlier stage.
• Efficient multi-cell monitoring: With a single TTape device, multiple cells can be monitored, thus alerting the BMS sooner in case of overtemperature scenarios.
• Ultra-fast response: With a response time of less than one second, TTape guarantees quicker alerts, signalling the potential onset of thermal runaway conditions.
• Seamless integration: Calibration isn’t necessary. TTape can easily integrate with existing BMS, making it a go-to solution for many battery applications.

Moreover, the extremely thin design of TTape makes it ideal for conformal installations. With a single MCU input, its distributed temperature monitoring capability drastically improves the detection of localised cell overheating. This approach enables efficient cooling measures to prolong battery life and significantly heightens the safety standards of battery installations.

"Distinguishing itself from NTCs, TTape is a stellar addition to the Littelfuse product family. The profound advantage of localised cell overheating detection ensures quicker alerts to the BMS compared to traditional NTC setups," explained Tong Kiang Poo, Global Product Manager at Littelfuse. "The TTape Platform is a distributed temperature monitoring device for battery packs that helps to improve the detection of localised cell overheating. With no calibration or temperature lookup tables required, and only one MCU input needed, it integrates seamlessly with current BMS solutions alongside NTCs, delivering an enhanced detection of cell overheating.”

This groundbreaking product builds upon the Littelfuse legacy of innovation. It leverages the company's research, design, and development expertise in PPTCs, bringing forth a temperature monitoring solution that the industry eagerly awaits.

TTape promises to be a game-changer for the Li-ion battery pack market, emphasising safety and efficiency. As the industry moves rapidly towards more sustainable and safe energy solutions, Littelfuse products like TTape are a testament to the company's commitment to innovation and excellence.
