Causes of Thermal Runaway:
- External Factors: Mechanical damage, external heat, or short circuits can trigger the runaway.
Consequences of Thermal Runaway:
Prevention and Mitigation:
- Preventative Maintenance:Adjusting charging voltage, ensuring proper ambient temperatures, and replacing older batteries before failure are essential.
Safety Measures:
Internal sensors, cooling systems, and containment measures can be implemented to detect and mitigate thermal runaway.
Safe Battery Design:
Using
materials with improved thermal stability and designing battery packs
with appropriate cooling mechanisms can minimize the risk of thermal
runaway.
Tesla's crash protection methods for EV batteries:
This includes water injection into failing cells, cooling surrounding cells to prevent a chain reaction, and pack isolation.
