Cross-section walkthrough
Layer by layer, from road surface to cabin floor.
You'll learn
- Explain cross-section walkthrough at engineering level
- Read the numbers that define the behaviour
- Apply the idea to a real pack
Overview
Slice a modern pack vertically and you can read the entire design philosophy in about ten layers.

Key takeaways
Remember this
- Heat leaves cells through the interface material into the cooling plate.
- Barriers and vent channels shape runaway behaviour.
- The lid is increasingly the cabin floor itself.
