Thermal Runaway Propagation Technical Meeting
Tuesday, November 19
5:30 - 8:00 p.m.
San Marino Club, Troy
1685 E Big Beaver Rd, Troy, MI 48083
Thermal runaway propagation (TRP) occurs in a battery electric vehicle (BEV) when a single Li‑ion cell becomes unstable by transferring enough thermal energy to its neighbors that they too are triggered to instability.
Understanding and mitigating against thermal propagation is one of the most difficult challenges currently facing BEV designers, as well as being a tightly coupled, stochastic problem that often defies Multiphysics simulation. Within automotive OEMs, TRP cuts across multiple engineering domains and organizational boundaries, touching on cell chemistry and lifecycle, thermal management, electrical bus layout, structural design, pack sealing, material selection, instrumentation, and software.
The following will be discussed:
- Estimating heat release from a Li-ion cell in thermal runaway
- The various pathways thermal energy can take
- The relative importance of thermal barriers, active cooling, and gas management
- The quantities and qualities of solid-, liquid-, and gas-phase ejecta
- Data from mini-module thermal propagation testing
- System engineering and prioritization when designing a TRP solution
Aspen Aerogels has emerged as an industry leader in the cell-to-cell barrier space, providing aerogel-based solutions to BEV OEMs such as GM, Toyota, and Scania. Aspen’s Aerogel Technology Platform® has 20+ years of providing thermal and passive fire protection in some of the world’s most challenging applications. The company's PyroThin® thermal barriers were recently honored with Automotive News’ PACE Award and the Innovation Partnership Award.
