DC fast charging bypasses the onboard charger and feeds high-voltage power directly to the battery, which is how modern EVs can go from 10 to 80 percent in 18 to 40 minutes. Real-world speed depends on three things: the charger rating, the vehicle maximum charge rate, and the battery state of charge, since charging slows sharply past 80 percent to protect the pack. Expect to pay two to three times home electricity rates at public fast chargers, which is why most owners reserve them for road trips. Plan stops around the 10 to 60 percent window, where charging is fastest, rather than waiting for a full battery.
