Time to full charge by charger type (10 → 100%)

Times shown are approximate 10–100% SoC. Actual times vary by BMS, ambient temperature, and battery state. DC fast charging slows above 80% due to cell protection.

Battery capacity degradation over time
Usable kWh % capacity Warranty threshold (70%)

Curves are based on empirical degradation models. LFP cells degrade slowest (~1.5%/yr), NCA fastest (~3%/yr). Real-world varies by temperature, depth of discharge, and charge frequency.
