TTape: A simple way to monitor Li-ion battery-pack temperature

January 18, 2024 By Martin Rowe

Littelfuse TTape

A set of temperature-triggered switches alerts you to hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write software to produce an […]
