Why Is Thermal Runaway?

Thermal runaway begins when the heat generated within a battery exceeds the amount of heat that is dissipated to its surroundings. ... The rise in temperature in a single battery will begin to affect other batteries in close proximity, and the pattern will continue, thus the term “runaway.”

How thermal runaway is occur?

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. ... In electrical engineering, thermal runaway is typically associated with increased current flow and power dissipation.

How can thermal runaway be avoided?

To minimize the risk of thermal runaway, the mechanical and thermal stability of the battery must be guaranteed. This is ensured by appropriate monitoring mechanisms of the battery cells and the battery pack.
