# Battery Thermal Dynamics & Degradation Benchmark

## Empirical Fast-Charging Benchmarks

### Active Cooling Degradation Metrics
Under continuous 350kW DC fast charging, active liquid glycol thermal management reduced capacity degradation by 43.2% compared to passive dissipation across 1,000 charge cycles.

### Solid State Capacity Retention
Solid-state electrolyte pouch cells demonstrated 91.4% capacity retention after 1,500 stress cycles at 45°C ambient temperature.
