CCS1 is the fast-charging standard used by most electric vehicles sold in North America

CCS1 (Combined Charging System Type 1) is the connector standard for DC fast charging on nearly all electric vehicles sold in the United States and Canada. If you own a Tesla Model 3, Chevrolet Bolt, Ford F-150 Lightning, Hyundai Ioniq 5, or most other non-Tesla EVs made after 2015, your vehicle has a CCS1 port. The connector combines AC charging pins with DC fast-charging pins in a single inlet, which is why it's called "combined."

CCS1 chargers come in two main types: Level 2 chargers (which use the AC pins and deliver 7 to 19 kilowatts) and DC fast chargers (which use the full connector and deliver 50 kilowatts or more). Most public charging networks in North America — including Electrify America, EVgo, and Chargepoint — operate CCS1 DC fast chargers. Understanding which type you need and where to find them matters for trip planning and daily charging decisions.

Key Takeaways

  • CCS1 is the standard DC fast-charging connector for most North American electric vehicles, though Tesla vehicles use a different connector and require an adapter to use CCS1 chargers.
  • DC fast chargers add 100 to 200 miles of range in 20 to 40 minutes, while Level 2 chargers add 25 to 30 miles per hour of charging and are better for overnight home charging.
  • Public CCS1 DC fast-charging networks are denser along highways and in urban areas, but coverage varies significantly by region and state.
  • Home Level 2 CCS1 chargers typically cost $500 to $2,000 installed and charge overnight, while DC fast chargers are only found at public stations and cost $0.25 to $0.50 per kilowatt-hour.
  • Charging speed depends on both the charger's power output and your vehicle's onboard capability, so a 350-kilowatt charger may deliver only 150 kilowatts to your car if that is your vehicle's maximum rate.

How CCS1 charging speeds compare to other connector types

CCS1 chargers are rated by power output in kilowatts. A 50-kilowatt charger adds roughly 150 miles of range in 30 minutes on most vehicles. A 150-kilowatt charger adds the same distance in 10 to 15 minutes. A 350-kilowatt charger (the fastest currently deployed) can add 200 miles in 20 minutes on compatible vehicles, though most cars cannot accept power at that rate for the full charge.

The actual speed you experience depends on two factors: the charger's power output and your vehicle's maximum charging rate. A Chevrolet Bolt EV accepts up to 150 kilowatts, so plugging it into a 350-kilowatt charger will not make it charge faster than 150 kilowatts. A Hyundai Ioniq 6 accepts up to 233 kilowatts and will charge noticeably faster at a 350-kilowatt station. Temperature also matters — cold batteries charge more slowly as a safety measure, and charging speed drops as the battery fills past 80 percent.

Tesla vehicles use the North American Charging Standard (NACS), a different connector. Tesla owners can use CCS1 chargers with an adapter, but the adapter adds cost and is not always available at every station. Most new Teslas come with an adapter included.

Where to find CCS1 chargers and how to use them

The three largest CCS1 DC fast-charging networks in North America are Electrify America (over 900 stations), EVgo (over 800 stations), and Chargepoint (over 300 DC fast-charging locations). Smaller networks include Volta, Tesla Superchargers (with adapters), and regional operators. Most are concentrated along Interstate corridors and in metropolitan areas. Rural coverage remains sparse in many states.

To find a CCS1 charger, use your vehicle's built-in navigation system, which typically shows real-time availability and pricing. Standalone apps like PlugShare, A Better Route Planner, and each network's own app also show locations, wait times, and whether chargers are currently working. Pricing varies by network and location: most DC fast chargers cost between $0.25 and $0.50 per kilowatt-hour, though some charge a flat session fee instead. Membership plans with monthly fees can lower per-kilowatt-hour rates if you charge frequently.

Using a public CCS1 charger is straightforward. Plug in, open the charger's app or tap your payment card, and the charger begins delivering power. Most sessions take 20 to 45 minutes. Some chargers have idle fees if you leave your car plugged in after charging completes, so set a phone reminder to unplug when the session ends.

Installing a Level 2 CCS1 charger at home

A Level 2 CCS1 charger at home is the most practical daily charging solution for most EV owners. These chargers plug into a 240-volt circuit (the same voltage as an electric dryer or range) and deliver 7 to 19 kilowatts depending on the model and your home's electrical service. A typical Level 2 charger adds 25 to 30 miles of range per hour, so an overnight charge replaces a full day's driving for most commuters.

Installation costs range from $500 to $2,000 depending on how far the charger is from your electrical panel and whether your home's service needs an upgrade. A charger 50 feet from the panel costs less than one 200 feet away. If your home has older 100-amp service, upgrading to 200-amp service (which many Level 2 chargers require) adds $1,500 to $3,000 to the total. Get quotes from licensed electricians in your area — prices vary significantly by region and local labor costs.

Popular home Level 2 chargers include the Tesla Wall Connector (which works with non-Tesla vehicles via adapter), Chargepoint Home Flex, Eaton Wallbox, and Grizzl-E. Most come with a 25-foot cable and a weatherproof housing. Installation typically takes one day. Some utilities offer rebates for home charger installation, so check your local electric company's website before purchasing.

CCS1 versus other charging standards in North America

Until recently, North America had two competing standards: CCS1 (used by most non-Tesla vehicles) and Tesla's proprietary connector. In 2023, Tesla began opening its Supercharger network to other vehicles via adapters, and the industry began transitioning toward the North American Charging Standard (NACS), which Tesla developed. NACS is now the official standard adopted by most major automakers, though CCS1 chargers will remain in use for many years.

For practical purposes, if you own a non-Tesla EV built before 2024, you have a CCS1 port and will use CCS1 chargers. Newer vehicles may have NACS ports instead, which limits your access to existing CCS1 networks unless you carry an adapter. If you are considering buying an EV, check whether it uses CCS1 or NACS — this affects which public chargers you can use and whether you need to buy adapters.

Level 1 charging (using a standard 120-volt household outlet) is available on all EVs but is impractically slow for most owners, adding only 2 to 5 miles per hour. It is useful only as a backup or for vehicles that sit unused for days.

Charging costs and how to estimate your expenses

Home Level 2 charging costs roughly $0.03 to $0.06 per mile, depending on your local electricity rate. If your utility charges $0.14 per kilowatt-hour and your vehicle uses 0.25 kilowatt-hours per mile, charging at home costs about $0.035 per mile. Public DC fast charging costs roughly $0.08 to $0.15 per mile at current rates, making it two to three times more expensive than home charging.

For a 300-mile road trip, charging at a public DC fast charger costs $24 to $45. Charging at home overnight costs $10 to $21 for the same distance. This is why most EV owners do daily charging at home and use public chargers only for trips. If you do not have access to home charging (apartment dwellers, for example), public charging costs add significantly to your ownership expenses.

Some networks offer subscription plans. Electrify America's monthly plans range from $4 to $29 depending on usage tier. EVgo offers a similar structure. If you charge publicly more than twice a week, a subscription plan usually saves money compared to pay-per-use rates.

Troubleshooting common CCS1 charger problems

The most common issue is a charger showing as "out of service" when you arrive. This happens because chargers malfunction and networks do not always update their apps when ready. Before driving to a charger, check the app within 15 minutes of arrival to confirm it is working. If a charger fails mid-session, most networks refund the session fee if you report it through the app.

Slow charging speed usually means either the charger is delivering less power than rated (often due to high demand or cold weather) or your vehicle has reached its maximum charging rate. Check your vehicle's display to see the actual kilowatts being delivered. If it is much lower than the charger's rating, try unplugging and plugging back in, or move to a different charger if available.

Payment issues are rare but happen when a card is declined or an app fails to authenticate. Carry a backup payment method (a different card or cash if the network accepts it) when traveling. Most networks allow you to add payment methods through their app before you need them.

Cold weather reduces charging speed significantly — a charger that delivers 150 kilowatts in summer may deliver only 80 kilowatts in winter. This is normal and protects your battery. Plan for longer charging times in cold climates.

Frequently Asked Questions

Can I use a CCS1 charger if my car has a different connector?

Only if you have an adapter. Tesla vehicles can use CCS1 chargers with the Tesla-to-CCS1 adapter. Vehicles with NACS ports cannot use CCS1 chargers without an adapter, and adapters for NACS-to-CCS1 are not yet widely available. Check your vehicle's manual or contact the manufacturer to confirm what adapters are compatible.

How long does it take to install a home Level 2 charger?

Installation typically takes one day once an electrician has assessed your home's electrical panel and determined whether an upgrade is needed. If your panel needs upgrading, the total project takes two to three days. Scheduling is usually the longest part — many electricians have waiting lists of two to four weeks.

What is the difference between kilowatts and kilowatt-hours on a charger?

Kilowatts (kW) is the rate of power delivery — how fast the charger is adding energy. Kilowatt-hours (kWh) is the total amount of energy delivered. A 150-kilowatt charger delivering power for one hour adds 150 kilowatt-hours to your battery. Your charging bill is based on kilowatt-hours, not kilowatts.

Do I need to own a CCS1 charger to use public chargers?

No. Public chargers are owned and operated by charging networks. You only need a CCS1 port on your vehicle and a payment method (credit card or app account) to use them. Home chargers are optional and useful only if you have a driveway or garage and want to charge overnight.

Will CCS1 chargers become obsolete as NACS becomes standard?

CCS1 chargers will remain in use for at least 10 to 15 years because millions of vehicles on the road have CCS1 ports. Networks are not removing CCS1 chargers; they are adding NACS chargers alongside them. If you buy a CCS1 vehicle today, you will have access to public chargers throughout its lifespan.
