Define thermal runaway
Thermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature. Thermal runaway occurs in situations where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result. It is a kind of uncontrolled positive feedback. WebMay 16, 2024 · Monday, 16 May 2024. Thermal runaway is a chain reaction that results from too much heat building up inside of a battery pack.
