How Long It Really Takes to Charge Your EV at Home
One of the biggest questions for new and prospective electric vehicle owners is a simple one: “How long will it take to charge at home?” The answer isn’t a single number, but the good news is that for most people, charging your EV at home is the most convenient and effortless way to power up. You simply plug in when you get home, and by the next morning, you have a “full tank.” Let’s break down exactly what you can expect and how you can optimize your routine to charge at home efficiently.
The time it takes to charge at home primarily depends on three key factors:
- The type of home charging equipment you use.
- The size of your car’s battery.
- Your car’s built-in charging capacity.
Understanding these elements will help you set realistic expectations and choose the best setup for your lifestyle.
Level 1 Charging: The Convenience Outlet (But So, So Slow)
This is the most basic way to charge at home. Level 1 charging uses a standard 120-volt household outlet—the kind you plug your lamp or TV into. Every EV comes with a cable for this purpose.
- Power Delivery: About 1.2 to 1.4 kilowatts (kW).
- Range Added: Roughly 3 to 5 miles of range per hour.
- Real-World Time to Charge at Home: If you have a typical EV with a 60-80 kilowatt-hour (kWh) battery and you come home with a nearly empty battery, it could take over 48 hours to get a full charge.
When it makes sense: Level 1 charging can work if you have a plug-in hybrid with a small battery or a very short daily commute (less than 30-40 miles). For most full-time EV drivers, however, relying solely on a standard outlet to charge at home is frustratingly slow and often impractical. It’s best used as a portable backup, not your primary method to charge at home.
Level 2 Charging: The Home Charging Hero
This is the solution that makes owning an EV truly convenient. A Level 2 home charger requires a 240-volt electrical circuit, similar to what powers an electric dryer or oven. This is the system people refer to when they talk about installing a dedicated station to charge at home.
- Power Delivery: Typically between 6.2 kW and 11.5 kW (or higher).
- Range Added: A much more robust 20 to 60 miles of range per hour.
- Real-World Time to Charge at Home: This is where we get to the good part. Let’s use a common scenario: you have a 75 kWh battery and come home with 30% charge left, meaning you need to add about 52 kWh.
- With a mid-range 7.7 kW home charger, you can charge at home and add that 52 kWh in about 6-7 hours.
- With a faster 11.5 kW home charger, that time drops to just 4.5 hours.
For the vast majority of drivers, this means you can easily charge at home overnight, no matter how low the battery is when you plug in. You will wake up to a full battery every single morning. This ability to charge at home overnight is the secret to effortless EV ownership.
The Crucial Details That Affect Your Home Charging Speed
While the charging level is the biggest factor, a few other details influence how long it will take you to charge at home.
1. Your Car’s Onboard Charger: The Internal Gatekeeper
Your EV has a component called an onboard charger that converts the AC power from your home charger into DC power to store in the battery. This charger has a maximum power rating it can accept. For example, if your car’s onboard charger is limited to 7.2 kW, buying a more powerful 11.5 kW home charger won’t make it charge faster. The car will only take what it can handle. It’s essential to know your vehicle’s maximum AC charging rate when planning how you charge at home.
2. Your Electrical Circuit’s Amperage
The circuit your electrician installs for your home charger determines its maximum power. A home charger on a 40-amp circuit can deliver up to 9.6 kW, while one on a 60-amp circuit can deliver 11.5 kW. A professional installation is key to getting the most out of your ability to charge at home safely and efficiently.
3. Battery Size and State of Charge
It’s simple math: a car with a large 100 kWh battery will take longer to charge at home than a car with a 40 kWh battery, assuming the same home charger. Also, charging slows down as the battery gets closer to full (especially above 80%) to protect the battery’s health. This is why most daily charging is done from 20-30% up to 80-90%.
Putting It All Together: A Realistic Home Charging Scenario
Let’s imagine Sarah, who drives a popular long-range EV.
- Car: Tesla Model Y Long Range (approx. 75 kWh battery)
- Daily Driving: 50 miles
- Home Charger: Level 2, 9.6 kW (on a 40-amp circuit)
- Goal: Recharge daily from 70% to 90% (about 15 kWh needed)
How long does it take Sarah to charge at home?
- Her home charger delivers 9.6 kW per hour.
- To add 15 kWh, she needs (15 kWh / 9.6 kW) = approximately 1.6 hours.
In less than two hours while she sleeps, Sarah has replaced all the range she used that day. This is the typical, seamless experience of using a home charger. You aren’t waiting for the car; the car waits for you.
Smart Charging: Optimizing Your Home Charging Time
Modern home charger units are “smart.” You can plug your car in as soon as you get home, but use an app to schedule the home charger to start later, during off-peak electricity hours (e.g., after 11 PM). This saves you money and helps the electrical grid, all while ensuring your car is fully charged by morning. This smart scheduling makes it even more efficient to charge at home.
Conclusion: Overnight is the Magic Number
So, how long does it take to charge at home? With a standard outlet, it’s impractically slow for most. But with a Level 2 home charger, the answer is almost always: overnight. The specific time will vary based on your car and equipment, but the core promise remains. The true convenience of an EV isn’t fast public charging; it’s the ability to charge at home while you sleep, waking up every morning to a full “tank” and never having to visit a gas station again. Investing in a proper home charger is the key to unlocking this effortless reality.
