Charging Your EV at Home
Charging your electric vehicle (EV) at home is one of the greatest advantages of going electric. It's convenient, efficient, cost-effective, and gives you the confidence to start each day with a full charge. Whether you’re a first-time EV buyer or looking to upgrade your home setup, this guide provides everything you need to know to master home charging.
Why Home Charging Matters
Most EV owners do over 80 percent of their charging at home, and it's not just about convenience. Charging at home can reduce total ownership costs, improve battery longevity, and eliminate nearly all concerns about range.
At a national average of $0.14 per kWh, and with most EVs getting 3 to 4 miles per kWh, you’ll be paying around $0.04 per mile – far less than the cost of gasoline.
Types of Home Chargers
Level 1 Charging
- Power Source: Standard 120V outlet
- Speed: 3–5 miles of range per hour
- Best For: Plug-in hybrids or overnight top-ups with very low daily mileage
Level 2 Charging (Recommended)
- Power Source: 240V outlet (like a clothes dryer plug) or hardwired
- Speed: 12–40 miles of range per hour
- Best For: Daily charging for all EVs, including full battery electric vehicles

Installation Checklist
Before installing a charger, walk through the following steps:
- Evaluate your EV’s charging capacity
- Decide between a plug-in or hardwired unit
- Assess your electrical panel’s amperage (40A or more is recommended)
- Get a permit or professional home inspection if required
- Hire a licensed electrician to install and test the system
- Ensure the charger is UL or CSA certified
- Configure charge scheduling using the EV or charger app
Specialized Scenarios
Apartment or Condo Residents
- Look for available 120V or 240V outlets in your parking area
- Ask your HOA or landlord about installing shared chargers
- Use apps like PlugShare to locate public chargers nearby
Cold Climates
- Expect slower charging in subfreezing temperatures
- Use your app to precondition the battery before driving
Multi-EV Households
- Consider load-sharing chargers like the Tesla Wall Connector
- Explore dual-port systems or split circuits to manage total draw
Beyond the Basics: Smart Charging and Solar Integration
- Smart chargers allow you to schedule charging during off-peak hours to lower your electric bill.
- Pairing your EV charger with rooftop solar can significantly reduce or eliminate charging costs.
- Some newer chargers, like the Ford Charge Station Pro, support bidirectional charging, letting your vehicle power your home during outages or peak hours.
Understanding Circuit Load and Amperage
The amperage of your home charger directly affects how quickly your EV can charge. Higher amperage delivers more power, which shortens charging time. Here's how different levels compare for a typical 60 kWh battery:
- 16 amps:
- Charging speed: Approximately 3.8 kW
- Time to full charge: Around 16 hours
- 32 amps:
- Charging speed: Approximately 7.6 kW
- Time to full charge: Around 8 hours
- 48 amps:
- Charging speed: Approximately 11.5 kW
- Time to full charge: Around 5.5 hours
Tip:
Always size your circuit breaker at 125 percent of the charger's continuous load. For example, a 40-amp charger should be paired with a 50-amp circuit breaker to ensure safety and compliance.
Incentives and Rebates
- Federal Tax Credit: 30 percent of EVSE and installation cost, up to $1,000 for residential properties
- Utility Rebates: Many providers (e.g., PG&E, Con Edison) offer up to $500 back on installation
- State Programs: States like California and New York offer additional rebates
Use the GreenCars Incentive Tool to explore what is available in your area.
What EV Owners Say
“Charging at home costs me $38 a month versus $140 in gas previously.”
Jenna, Hyundai IONIQ 5 owner
“Installing a 50A circuit now saved me from redoing everything when we bought a second EV.”
Ray, Tesla Model Y owner
What You Need to Get Started
Here’s a checklist to prepare for home charging:
