Calculator notes
- AC charging speed is limited by your car's on-board charger (OBC), not the wall charger rating.
- DC fast charging bypasses the OBC — but DC charge rates taper above 80% to protect the battery.
- Real-world charge times are typically 5–10% longer than calculated due to charging losses and tapering.
- Some EVs (IONIQ 5/6, EV6, some BYD) have 800V architecture — they can use 350 kW DC chargers to reach 10–80% in under 20 minutes.
