What condition is characterized by continuous rising current and increased battery temperature?

The condition characterized by continuous rising current and increased battery temperature is known as thermal runaway. This phenomenon occurs when a battery experiences excessive heat, leading to a self-reinforcing cycle where the temperature rises, increasing the rate of chemical reactions within the battery. This can cause even more heat to be generated, resulting in a continuous rise in current and further temperature elevation.

As the battery temperature increases, it may reach a point where it can lead to danger, including potential fire or explosion. Thermal runaway is particularly a concern with lithium-ion batteries but can occur in other types as well when they are subjected to malfunctions or extreme charging conditions. Understanding this condition is crucial for maintaining battery safety and performance in aviation and other applications.
