Frequently asked questions
- How long does it take to charge an EV?
- It depends on battery size and charger speed. A Level 2 7.2 kW charger adds about 25–30 miles per hour. A 50 kW DC fast charger can charge from 20–80% in about 30–60 minutes for a 75 kWh pack.
- Should I charge my EV to 100%?
- Most EV manufacturers recommend daily charging to 80% to preserve battery longevity. Only charge to 100% before a long trip when you need maximum range.
