How Long Does It Take to Charge an EV with a 240-Volt Outlet?
Last updated: October 2025
Discover EV charging times with 240V outlets, installation requirements, and how Level 2 charging compares to other options for home EV charging.
With a 240V outlet, most EVs charge in ~6-12 hours (0-100%) when using ~7.7-11.5 kW equipment.
Daily top-ups usually take ~1-3 hours.
A NEMA 14-50 (40 A continuous ≈ 9.6 kW) typically delivers ~25-40 miles of range per hour on many EVs.
Budget NEMA 6-20 (16 A ≈ 3.8 kW) is slower at ~10-15 miles/hour.
Time (hrs) ≈ Battery kWh ÷ (Charger kW × 0.90). Example: 75 kWh ÷ (11.5 × 0.90) ≈ 7.2 h.
What is 240V Charging?
240V charging, also known as Level 2 charging, uses the same voltage as large household appliances like electric dryers and ovens. It's the most popular home EV charging solution, offering a good balance of charging speed and installation cost.
Charging Level | Voltage | Typical Power | Miles per Hour |
---|---|---|---|
Level 1 | 120V | 1.4kW | 2-5 miles |
Level 2 (240V) | 240V | 3.3-19.2kW | 10-60 miles |
DC Fast Charging | 480V+ | 50-350kW | 100-300+ miles |
NEMA 14-50 (Most Popular)
- • 50-amp outlet, 40 A continuous (≈9.6 kW)
- • Same outlet used for electric RVs and welders
- • Provides 25-40 miles of range per hour for most EVs
NEMA 6-20 (Budget Option)
- • 20-amp outlet, 16 A continuous (≈3.8 kW)
- • Less expensive to install than 14-50
- • Provides 10-15 miles of range per hour
Hardwired Chargers
- • Up to 48 A (≈11.5 kW) common; some support 80 A (≈19.2 kW) on suitable circuits and vehicles
- • More permanent installation, often with smart features
- • Provides 40-60+ miles of range per hour

Vehicle Model | Battery Size | Max AC Rate | 0-100% Time | Daily Top-up |
---|---|---|---|---|
Tesla Model 3 (Standard) | 54 kWh | 11.5kW | 5-6 hours | 1-2 hours |
Tesla Model Y (Long Range) | 75 kWh | 11.5kW | 7-8 hours | 1-3 hours |
Ford Mustang Mach-E | 68-91 kWh | 10.5kW | 7-10 hours | 2-3 hours |
Hyundai Ioniq 5 | 58-77 kWh | 11kW | 6-8 hours | 1-3 hours |
Chevrolet Bolt EV | 65 kWh | 11kW | 6-7 hours | 1-2 hours |
Ford F-150 Lightning | 98-131 kWh | 11.5 kW (19.2 kW with Charge Station Pro & dual onboard charger) | ~10-13 hours | 2-4 hours |
Note: Actual charging times may vary based on ambient temperature, battery condition, and electrical supply quality. Times shown assume optimal conditions. With 19.2 kW hardware, 0-100% can be ~6-8 h.
Installation Requirements
- • Electrical panel capacity: Must have available breaker slots and sufficient amperage
- • Circuit breaker: Dedicated 40-50 amp breaker for NEMA 14-50 outlet
- • Wiring: 6 AWG copper wire for 50-amp circuits, 8 AWG for 40-amp
- • Distance: Longer runs from panel increase installation cost
- • Permits: Most areas require electrical permits for 240V installations
Installation Costs
Installation Type | Cost Range | Description |
---|---|---|
Simple | $300-600 | Panel nearby, no obstacles |
Standard | $600-1,200 | Moderate distance, some complexity |
Complex | $1,200-2,500 | Panel upgrade, long runs, obstacles |
Charging Schedule Optimization
- • Time-of-use rates: Charge during off-peak hours (typically 11 PM - 7 AM)
- • Daily routine: Plug in when you get home, let the car manage charging timing
- • Battery health: Charge to 80% for daily use, 100% only before long trips
- • Temperature considerations: Garage charging is more efficient than outdoor charging
Smart Charging Features
- • Scheduled charging: Set departure times to optimize for electricity rates
- • Load balancing: Smart chargers can adjust power based on home electrical usage
- • Solar integration: Charge during peak solar production hours
- • Remote monitoring: Track charging progress and costs through mobile apps
Troubleshooting Common Issues
- • Slow charging: Check for voltage drop, loose connections, or high ambient temperature
- • Charging stops: May indicate ground fault, overheating, or electrical issues
- • Inconsistent speeds: Could be due to shared circuits or utility voltage fluctuations
- • No charging: Verify outlet power, check vehicle charging settings, inspect cable
