Thermal Runaway Is a Systems Problem, Not a Cell Problem
From cell chemistry to pack architecture to fast-charge protocol, thermal behavior decides safety margin, cycle life, and how a storage system ages over its service life.
Why thermal decides the outcome here
Thermal runaway propagation, not average pack temperature, is what safety standards and insurers actually care about. Cold-plate channel design and fast-charge thermal limits decide whether a pack meets its cycle-life target or degrades early.
Engineering Challenges
- Cell electrochemical-thermal coupling under charge and discharge
- Thermal runaway propagation and containment
- Pack-level thermal gradients between cells
- Cold-plate channel design and coolant flow distribution
- Fast-charge thermal limits and derating
- Second-life aging and capacity fade under thermal history
Dominant Thermal Physics
- Electrochemical heat generation coupled to cell thermal response
- Thermal runaway propagation between adjacent cells
- Pack-level thermal gradient formation
- Cold-plate channel conduction-convection
- Aging-driven internal resistance and heat generation changes
