Why bigger batteries do not always charge slower
DC charging time depends on peak power and how long the car holds it, not just battery size. The Hyundai Ioniq 5 and 6 use an 800 V system and stay near their peak for longer, so they beat smaller-battery cars from 10% to 80%. At home the limit is the onboard charger (usually 11–11.5 kW), so time grows with battery size.
Frequently asked questions
Which EV charges the fastest?
Among popular US models, the Hyundai Ioniq 6 is the quickest from 10% to 80%, in about 18 min on a fast enough charger.
How long does an EV take to charge at home?
Most take 7–12 hours from empty to full on a 48 A Level 2 charger. In daily use you only replace the miles you drove, which usually takes 1–3 hours.
