Key benefits
- 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.
Additionally, TTape's ultra-thin profile makes it incredibly suitable for snug installations. It utilizes a singular MCU input for its distributed temperature monitoring system, which drastically enhances the identification of hot spots within individual cells. This design enables more effective cooling strategies that extend the battery's durability while significantly elevating the safety protocols of battery setups.
"Tape stands out from conventional NTC thermistors as an exemplary new member of Littelfuse's suite of products. Its key benefit lies in the rapid detection of hot cells, providing faster notifications to the Battery Management System (BMS) than traditional NTC assemblies," stated Tong Kiang Poo, the Global Product Manager for Littelfuse. "TTape is a dedicated temperature monitoring solution for battery packs, designed to boost the detection of cell-specific overheating. It eliminates the need for calibration or temperature reference charts and only requires a single MCU input, allowing for straightforward integration with existing BMS infrastructures, including those using NTCs, thereby improving overheating detection."
This innovative offering continues the legacy of Littelfuse's pioneering spirit. It capitalizes on the company's extensive experience in Positive Temperature Coefficient (PPTC) technology to deliver a temperature monitoring solution that fulfills a critical industry need. TTape is poised to transform the Li-ion battery pack sector with its focus on safety and operational efficiency. As the global trend shifts towards more reliable and environmentally friendly energy sources, Littelfuse's dedication to pioneering products like TTape demonstrates the company's ongoing commitment to innovation and superior performance. The TTape Distributed Temperature Monitoring Platform is available in various packaging options, including tape and reel or box formats, tailored to the required length.
