Littelfuse TTape Overtemperature Detection Platform for EV Li-ion Battery Packs

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 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 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.
