"The temperature in a battery will escalate in an exponential manner and it will cause fire," Goswami said. An electric vehicle battery pack typically contains over 1,000 cells, setting the stage for a domino effect if thermal runaway occurs in one cell, threatening the entire battery system."
"We need to move to green energy," Goswami said, "but there are safety concerns associated with lithium-ion batteries." This highlights the balance between environmental goals and the safety of electric vehicle technology.
The framework combines multiphysics and machine learning models to sense, predict, and identify lithium-ion battery overheating, a critical advancement for improving electric vehicle safety.
By wrapping thermal sensors around battery cells, the researchers aim to leverage historical data and machine learning algorithms to predict temperatures and prevent thermal runaway incidents effectively.
