Littelfuse Corporation (NASDAQ: LFUS) is an industrial technology manufacturing company dedicated to powering a sustainable, connected and safer world. The company introduced TTape™, a breakthrough overtemperature detection platform to improve the management of lithium-ion battery systems. With its innovative features and unparalleled advantages, TTape helps automotive systems effectively control premature battery aging while reducing the risks associated with thermal runaway accidents.

TTape is ideal for a wide range of applications, including electric/hybrid vehicles, commercial vehicles and energy storage systems (ESS). Its distributed temperature monitoring function provides sensitive detection of local battery overheating, thereby extending battery life and improving the safety of battery installation.

Key benefits and features of TTape include:

Premature Battery Aging Management: TTape helps vehicle systems manage the issue of premature battery aging, significantly reducing the risks associated with thermal runaway.
Extend battery life: TTape ensures that the battery pack stays usable for longer by activating temperature management at an early stage.
Efficient multi-battery monitoring: Multiple batteries can be monitored using a single TTape device, alerting BMS faster in the event of overtemperature conditions.
Ultra-fast response: The response time of TTape is less than one second, which ensures faster warning of possible thermal runaway conditions.
Seamless integration: No calibration required. TTape is easily integrated with existing BMS and is the solution of choice for many battery applications.
In addition, TTape’s ultra-thin design also makes it ideal for form-preserving installations. With a single MCU input, the distributed temperature monitoring function greatly improves the detection ability of local battery overheating. This approach enables effective cooling measures, extended battery life, and significantly improved safety standards for battery installation.

“TTape is distinct from NTC and is an important addition to the Littelfuse product family. The great advantage of local battery overheating detection over traditional NTC Settings ensures faster alerting to the BMS.” Tong Kiang Poo, global Product Manager at Littelfuse, explains, “The TTape platform is a distributed temperature monitoring device for battery packs that helps improve the detection of localized battery overheating. It requires no calibration or temperature lookup tables and requires only one MCU input to seamlessly integrate with current BMS solutions and NTC to enhance the detection of battery overheating.”

This breakthrough product continues Littelfuse’s tradition of innovation. It leverage the company’s research, design and development expertise in PPTC to deliver a much-anticipated temperature monitoring solution.

TTape’s emphasis on safety and efficiency is expected to change the landscape of the lithium-ion battery pack market. As the industry moves rapidly towards more sustainable and safer energy solutions, products such as Littelfuse’s TTape are a testament to the company’s commitment to innovation and excellence.
