The operation of lithium-ion batteries requires accurate thermal monitoring to ensure safe operating conditions and to optimize battery charging performance.
With the TTape™ platforms, Littelfuse offers the option of placing many measuring points in a multi-cell battery pack. This increases the spatial resolution of temperature monitoring and simplifies the installation process.
Using a two-wire interface, their sensors detect localized cell overheating: they activate at a temperature of 58 °C +/- 3 °C and reset at a temperature of 42 °C +/- 3 °C. Standard NTC temperature sensors only detect thermal runaway in the specific cell to which they are attached. TTape™, on the other hand, impresses with an ultra-fast response time of less than one second when any cell in the entire battery pack overheats. This drastically reduces the time it takes for the BMS to initiate countermeasures and makes thermal management easier and more efficient.
The signal can also be used as a watchdog to wake the MCU from sleep mode in the event of overheating. By monitoring each individual battery cell, the TTape™ platform helps to meet safety requirements and prevent thermal runaways.
