CCS1 is the combined charging standard used by most North American electric vehicles
CCS1 (Combined Charging System Type 1) is the fast-charging connector standard adopted by most automakers selling vehicles in the United States and Canada. It combines AC charging and DC fast charging into a single plug, so the same port on your vehicle can handle both everyday charging at home and rapid charging at public stations.
The connector itself is a Type 1 plug — the same shape used for Level 1 and Level 2 AC charging — with two additional DC pins at the bottom. This design means your car's onboard charger handles the conversion from AC to DC when you plug in at home, while DC fast chargers do the conversion themselves and deliver power directly to the battery.
CCS1 became the dominant standard in North America because major manufacturers including General Motors, Ford, Volkswagen, BMW, and Hyundai adopted it. Tesla vehicles sold in North America since late 2023 also use CCS1, though they originally used a proprietary connector called the Tesla Supercharger plug.
Key Takeaways
- CCS1 is a single connector that handles both AC home charging and DC fast charging at public stations.
- The standard is used by most major automakers in North America, though some older vehicles and imports may use different connectors.
- DC fast charging with CCS1 can add 200 miles of range in 20 to 30 minutes, depending on the charger and vehicle.
- CCS1 chargers are increasingly common at public networks, but availability varies by region and network operator.
How CCS1 charging speeds compare to other standards
CCS1 supports three charging levels, each with different power delivery and charging times. Level 1 uses a standard 120-volt household outlet and delivers about 1.4 kilowatts; charging a typical EV battery from empty takes 24 to 48 hours. Most people use Level 1 only as a backup or for overnight charging when they drive short distances daily.
Level 2 charging uses a 240-volt circuit (the same voltage as a clothes dryer or electric range) and delivers 3 to 19 kilowatts depending on the charger and vehicle. A Level 2 charger at home typically adds 25 to 30 miles of range per hour, so a full charge overnight is practical for most drivers. Public Level 2 chargers are common at shopping centers, parking garages, and workplaces.
DC fast charging bypasses the vehicle's onboard charger and delivers power directly to the battery at 50 to 350 kilowatts. A 150-kilowatt CCS1 fast charger can add 200 miles of range in 20 to 30 minutes on compatible vehicles. Charging speed depends on the charger's power output, the vehicle's battery capacity, and the battery's current state of charge — most vehicles charge fastest when the battery is partially depleted and slow down as it approaches full capacity.
CCS1 versus other EV charging connectors in use today
Three main connector standards exist for electric vehicles in North America, and the one your vehicle uses depends on when and where it was built. CCS1 dominates new vehicle sales, but older vehicles and some imports use different plugs, which means you cannot charge them at every public station.
| Connector | Used By | AC Charging | DC Fast Charging |
|---|---|---|---|
| CCS1 | Most new EVs: GM, Ford, Volkswagen, BMW, Hyundai, Tesla (2023+) | Yes, Level 1 and Level 2 | Yes, 50–350 kW |
| Tesla Supercharger (proprietary) | Tesla vehicles built before late 2023 | No | Yes, 50–250 kW |
| CHAdeMO | Nissan Leaf, Mitsubishi i-MiEV, some older Kias | No | Yes, 50–200 kW |
Tesla's proprietary connector was the fastest and most widely available fast charger network in North America for years, but Tesla has been opening its Supercharger network to other brands and converting stations to CCS1. Older Nissan Leafs and a few other vehicles use CHAdeMO, a Japanese standard that is less common in North America and being phased out as networks upgrade to CCS1.
Where to find CCS1 chargers and how to use them
CCS1 chargers are available through several national and regional networks. Electrify America operates the largest CCS1 fast-charging network in the United States, with stations along highways and in urban areas. EVgo and Volta Charging operate smaller networks focused on urban and suburban locations. Many utilities and municipalities also operate their own Level 2 chargers, often at no cost or for a small fee.
Finding a charger requires a smartphone app or web search. Most networks have their own apps — Electrify America, EVgo, and ChargePoint are the most common — and many also appear on Google Maps when you search "EV charging near me." Apps show real-time availability, pricing, and connector type, which is important because some stations have multiple connector types at different ports.
Using a CCS1 charger at a public station typically requires creating an account with the network operator and linking a payment method. At DC fast chargers, you plug in, authenticate through the app or a card reader, and the charger begins delivering power. Charging sessions usually end automatically when the battery reaches 80 percent, because charging speed drops significantly after that point and continuing to full capacity takes much longer.
CCS1 charging at home versus public stations
Most EV owners do the majority of their charging at home using a Level 2 charger, which requires a 240-volt circuit and a dedicated charger unit. Installation typically costs between $500 and $2,500 depending on whether your home's electrical panel needs upgrades. Many utilities and some state programs offer rebates or tax deductions for home charger installation, though the amount varies by location and program.
Home charging is slower than DC fast charging but far more convenient — you plug in when you arrive and unplug when you leave, without waiting or paying per session. For drivers who travel less than 200 miles daily, home charging alone is usually sufficient. Public charging becomes necessary for longer trips or for drivers without access to home charging, such as apartment dwellers or those with limited parking.
The cost of public charging varies by network and location. Some networks charge by the kilowatt-hour (similar to electricity pricing), others charge by the minute, and a few offer subscription plans. DC fast charging typically costs $10 to $20 for a 20-minute session, while Level 2 charging at public stations often costs $2 to $5 per hour or is free.
Compatibility and future changes to CCS1
CCS1 compatibility is straightforward for vehicles built to the standard — any CCS1 charger works with any CCS1 vehicle. However, if you own an older Tesla, Nissan Leaf, or other vehicle with a different connector, you will need an adapter or access to a network that operates chargers for your specific plug type. Adapters exist for some combinations but not all, and they add cost and complexity.
The charging landscape is shifting toward CCS1 as the universal standard. Tesla's conversion of its Supercharger network to CCS1 and the phase-out of CHAdeMO stations means that within the next few years, CCS1 will be the only practical option for most drivers. If you are purchasing an electric vehicle, choosing one with CCS1 ensures access to the widest range of public chargers and future-proofs your charging options.
Internationally, CCS1 is used in North America, while Europe uses CCS2 (a larger connector with the same charging logic), and China uses GB/T. These standards are not compatible, so an EV built for one region cannot use chargers from another without significant modifications.
Frequently Asked Questions
Can I use a CCS1 charger with a Tesla built before 2023?
No. Older Teslas use Tesla's proprietary Supercharger connector, which is physically different from CCS1. Tesla is retrofitting its Supercharger network to include CCS1 ports, but older Tesla vehicles cannot use them without an adapter, which Tesla does not currently offer for home use.
How long does it take to charge an EV with CCS1 DC fast charging?
A typical session takes 20 to 40 minutes to add 200 miles of range, though this varies by charger power (50 to 350 kilowatts), vehicle battery size, and current charge level. Charging is fastest between 10 and 80 percent battery capacity; beyond 80 percent, the charger automatically reduces power to protect the battery.
What is the difference between CCS1 and Level 2 charging?
Level 2 uses AC power delivered through a 240-volt circuit and charges at 3 to 19 kilowatts, adding 25 to 30 miles per hour. CCS1 DC fast charging uses DC power delivered directly to the battery at 50 to 350 kilowatts, adding 200 miles in 20 to 30 minutes. Level 2 is practical for home and workplace charging; DC fast charging is for road trips.
Do I need to own a home charger if my car uses CCS1?
Not if you have access to public charging and drive short distances daily. However, home charging is more convenient and cheaper than relying on public stations. If you drive more than 100 miles daily or take frequent long trips, a home charger becomes practical.
