EV Charging Options at Home and on the Go

With more EVs on the road, it’s helpful to know what charging options are available. Find out more about home and public EV charging, comparing costs, charging speeds and installation needs.

For many EV drivers, home charging is the most convenient way to keep an EV powered up. Simply plug it in at the end of the day (or use your vehicle’s telematics or a smart charger to schedule charging overnight during off-peak hours), and by morning, your car is ready for the road. Read more about the best ways to save with EV charging.

Here are some frequently asked questions we’ve heard about EV home charging and public EV charging.

To support this expected boom in EV adoption, new charging infrastructure will be needed in places where people park their cars for extended periods of time, such as apartments and places of business. Why? For convenience and the time it takes to get a charge. But there are different types of chargers, so it's important to know which is right for your business.

What are my options for charging an EV at home?

Here are the main options for home EV charging options:

1. A Level 1 charger, which works with a regular household outlet.
2. A Level 2 charger uses a 240-volt outlet (like large household appliances use).
3. A smart charger, which is a Level 2 charger that is connected to your internet network.

Can I use a regular outlet to charge my EV?

Yes! If you use a Level 1 charger, you can charge an EV with a regular outlet. You should also use certified electricians to install and ensure the safety of your charging set-up. Ameren Missouri’s EV Partner Network makes it easy to find an electrical contractor partner in your area.

What’s the difference between Level 1 and Level 2 home charging?

Beyond cost, which is explained later, here are some differences between Level 1 vs. Level 2 EV charging.

1. Level 1 Charging: With this option, you’ll get about 4 miles of range per charging hour. If you schedule your EV to charge from 10 p.m.-7 a.m., that adds up to 36 miles of range ready to go when you wake up. This option works well for drivers who don’t need to drive long distances every day, or who can charge occasionally while at work.
2. Level 2 Charging: If you have a longer commute or frequently drive longer distances, level 2 charging works better. Level 2 charging provides around 25-40 miles of range per hour, so most EVs can reach an 80% charge overnight.
3. Smart Charger: A smart charger is a network-connected Level 2 charger with options that allow for remote control and scheduling, often through an app or online web portal. These chargers make it easy to schedule charging, take advantage of savings with electricity rate options, optimize energy consumption, and potentially save money. Your vehicle’s telematics could also be used to schedule charging—choose the option that works best for you.

How long does it take to charge an EV at home?

EV charging time at home depends on which level charger you have. Level 1 chargers charge more slowly because they use less voltage. You can get approximately 36 miles of range if you charge from 10 p.m.-7 a.m. You’d get the same amount in only 1 to 2 hours with a Level 2 charger, which uses a 240-volt plug and provides around 25-40 miles of range per charging hour.

How much does it cost to install a home EV charger?

Home EV charger installation cost varies by type and other factors. The average cost to install a Level 2 EV charger can range from $799 to $1,999, but it depends on charger type, installation complexity and location. Homeowners can also take advantage of available tax credits on charging equipment and installation through June 30, 2026. You can also check for available incentives in your state or municipality.

To help you select the best equipment for your needs, Ameren Missouri offers a Charger Comparison Tool, an easy way to compare Level 2 charging options.

Do I need special wiring or a dedicated circuit for home charging?

You might, but each home is different. It depends on how your garage or home is currently wired, how much space is available in your circuit breaker and what amperage you have. Check with an experienced electrician who knows EV charger electrical requirements.

Check out Ameren Missouri's charger installation checklist to help you determine the right at-home charger that fits your needs and to find an electrician to safely install the equipment.

Should I use a Level 2 or DC Fast Charging in public?

Level 2 vs. DC fast charging depends on your needs. When you’re on a longer journey or a road trip, public charging options offer you the flexibility of either a quick top-off or a full charge. Many public chargers are located near shopping centers, restaurants, airports, hotels, vacation rentals, as well as along highway corridors. Here’s what to look for:

• Level 2 Public Chargers are widely available at locations like parking garages, hotels and shopping centers. They provide around 25-40 miles of range per hour, making them a good choice if you plan to park for a few hours.
• DC Fast Charging quickly powers an EV from 10% to 80% in 30-40 minutes, making them perfect for long trips. Apps like PlugShare help you locate DC fast chargers along your route, with real-time availability updates and user reviews to guide your stops.

Both home and public charging offer unique benefits. EV charging options and resources are available to help you decide what’s best. Home charging delivers daily convenience and lower costs, while public charging provides speed and accessibility on the go. By understanding your options and comparing costs, you can make informed decisions that fit your lifestyle.
