Littelfuse unveils advanced overtemperature detection solution for electric vehicle Li-ion battery packs

12 January 2024

Littelfuse, Inc. now offers TTape, an overtemperature detection platform designed to transform the management of lithium-ion battery systems. With its innovative features and unparalleled benefits, TTape helps vehicle systems manage premature cell aging effectively while reducing the risks associated with thermal runaway incidents.

TTape is ideally suited for a wide range of applications, including automotive electric vehicles (EVs)/hybrid EVs, commercial vehicles and energy storage systems. Its distributed temperature monitoring capabilitiesSource: Littelfuse, Inc.Source: Littelfuse, Inc. enable superior detection of localized cell overheating, thereby improving battery life and enhancing the safety of battery installations.

TTape’s key benefits and differentiators include:

  • Premature cell aging management: TTape aids vehicle systems in managing premature cell aging, 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 battery management system (BMS) sooner in case of overtemperature scenarios.
  • Ultra-fast response: With a response time of less than one second, TTape guarantees quicker alerts, signaling 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 localized cell overheating. This approach enables efficient cooling measures to prolong battery life and significantly heightens the safety standards of battery installations.
