Littelfuse Introduces Advanced Over-Temperature Detection Solution for Electric Vehicle Lithium-Ion Battery Packs

TTape revolutionises the electric vehicle industry by providing the unique ability to detect overheating in every lithium-ion battery, improving superior safety and extending battery life.

CHICAGO, Jan. 24. 2024 - Littelfuse Corporation (NASDAQ: LFUS), an industrial technology manufacturing company

dedicated to powering a sustainable, connected and safer world.

The company is pleased to introduce TTape, a breakthrough over-temperature detection platform for improved management of lithium-ion battery systems.

With its innovative features and unrivalled benefits, TTape helps automotive systems effectively manage premature battery ageing while reducing the risks associated with thermal runaway incidents. Watch the video.

TTape is ideal for a wide range of applications, including electric/hybrid vehicles, commercial vehicles and energy storage systems (ESS).

Its distributed temperature monitoring provides sensitive detection of localised battery overheating, thereby extending battery life and improving the safety of battery installations.

Key benefits and features of TTape include:

● Premature Battery Ageing Management: TTape helps vehicle systems manage premature battery ageing issues, significantly reducing the risks associated with thermal runaway.

● Extended Battery Pack Life: TTape ensures that battery packs remain usable for longer by initiating temperature management at an early stage.

● Efficient Multi-Battery Monitoring: A single TTape device can monitor multiple batteries, alerting the BMS faster in the event of an over-temperature condition.

● Ultra-fast response: With a response time of less than one second, TTape ensures faster alerts to possible thermal runaway conditions.

Seamless Integration: With no calibration required, TTape integrates easily with existing BMSs, making it the solution of choice for many battery applications.

In addition, TTape's ultra-thin design makes it ideal for conformal installation. Using a single MCU input, the

Distributed temperature monitoring greatly improves the detection of localised battery overheating. This approach enables effective cooling measures, extends battery life and significantly improves the safety standards of battery installations.

‘TTape is distinct from NTC and is a great addition to the Littelfuse product portfolio. The huge advantage of localised battery overheating detection ensures faster alerts to the BMS compared to traditional NTC setups.

‘The TTape platform is a distributed temperature monitoring device for battery packs that helps improve detection of localised cell overheating,’ explains Tong Kiang Poo, global product manager at Littelfuse.

It eliminates the need for calibration or temperature look-up tables and seamlessly integrates with current BMS solutions and NTCs with a single MCU input to enhance the detection of battery overheating.’

This breakthrough product continues Littelfuse's tradition of innovation. It leverages the company's research, design and development expertise in PPTCs to deliver a temperature monitoring solution that is highly anticipated by the industry.

With an emphasis on safety and efficiency, TTape promises to change the landscape of the lithium-ion battery pack market. As the industry as a whole rapidly moves towards more sustainable and safer energy solutions.

products such as Littelfuse's TTape demonstrate the company's commitment to innovation and excellence.
