What is thermal runaway as it relates to EVs?
All EV traction battery fires start with thermal runaway Thermal runaway occurs when a battery cell short circuits & starts to heat up uncontrollably. Lithium ion batteries contain a large amount of energy in a very small space. Under normal operation, they rapidly convert chemical energy to electrical energy.
How does thermal runaway management work in EVs & HEVs?
Thermal runaway management in EVs and HEVs requires a three-pronged approach: In any case, stopping a battery thermal event happens through two methods — active and passive thermal management systems. Active thermal management relies on cooling systems that keep a battery pack at an optimal temperature.
What is thermal runaway?
When thermal runaway occurs, the cell is undergoing an unstable chemical reaction that is hard to bring under control. At some point, the separator structure collapses and the electrodes touch, causing an internal short circuit and masses of heat, catapulting the cell to ever higher temperature.
How does thermal runaway affect a lithium-ion cell?
In ideal conditions, the heat is able to dissipate from the cell. However, in thermal runaway, the lithium-ion cell generates heat at a rate several times higher than the rate at which heat dissipates from the cell. When its temperature rises at a rate greater than 20 degrees centigrade per minute, the cell has reached thermal runaway.
What happens if a battery gets thermal runaway?
If undetected, thermal runaway can lead to catastrophic results, including fire, explosion, sudden system failure, costly damage to equipment, and possibly personal injury. Thermal runaway can occur in lithium ion batteries and VLA, but this discussion focuses mainly on VRLA batteries, since they are most common in the industry.
