With the rapid global adoption of electric vehicles (EVs), the development of charging infrastructure has become a key focus in the industry. Currently, SAE J1772 and CCS (Combined Charging System) are the two most widely used charging standards in North America and Europe. This article provides an in-depth comparison of these standards, analyzing their charging types, compatibility, use cases, and future trends to help users choose the right charging solution for their needs.
1. What is CCS Charging?
CCS (Combined Charging System) is a versatile EV charging standard widely used in North America and Europe. It supports both AC (Alternating Current) and DC (Direct Current) charging through a single connector, offering great flexibility to users. The CCS connector combines standard AC charging pins (such as J1772 in North America or Type 2 in Europe) with two additional DC pins, enabling both slow AC charging and high-speed DC fast charging through the same port.
Advantages of CCS:
• Multi-functional Charging: Supports both AC and DC charging, suitable for home and public charging.
• Fast Charging: DC fast charging can typically charge a battery to 80% in under 30 minutes, significantly reducing charging time.
• Wide Adoption: Adopted by major automakers and integrated into an increasing number of public charging stations.
According to the European Automobile Manufacturers' Association (ACEA), as of 2024, over 70% of public charging stations in Europe support CCS, with coverage exceeding 90% in countries like Germany, France, and the Netherlands. Additionally, data from the U.S. Department of Energy (DOE) shows that CCS accounts for over 60% of public charging networks in North America, making it the preferred standard for highway and long-distance travel.
2. Which Vehicles Support CCS Charging?
CCS has become the dominant fast-charging standard in North America and Europe, supported by vehicles such as:
• Volkswagen ID.4
• BMW i4 and iX series
• Ford Mustang Mach-E
• Hyundai Ioniq 5
• Kia EV6
These vehicles are compatible with most high-speed charging networks, providing a convenient experience for long-distance travel.
According to the European Association for Electromobility (AVERE), over 80% of EVs sold in Europe in 2024 support CCS. For instance, the Volkswagen ID.4, a top-selling EV in Europe, is highly praised for its CCS compatibility. Additionally, research by the American Automobile Association (AAA) indicates that Ford Mustang Mach-E and Hyundai Ioniq 5 owners highly value the convenience of CCS fast charging.
3. What is J1772 Charging?
SAE J1772 is the standard AC (Alternating Current) charging connector in North America, primarily used for Level 1 (120V) and Level 2 (240V) charging. Developed by the Society of Automotive Engineers (SAE), it is compatible with nearly all EVs and plug-in hybrid electric vehicles (PHEVs) sold in North America.
Features of J1772:
• AC Charging Only: Suitable for slow charging at home or workplaces.
• Wide Compatibility: Supported by almost all EVs and PHEVs in North America.
• Home and Public Use: Commonly used in home charging setups and public AC charging stations.
According to the U.S. Department of Energy (DOE), over 90% of home charging stations in North America use J1772 as of 2024. Tesla owners can charge their vehicles at most public AC stations using a J1772 adapter. Additionally, a report by Electric Mobility Canada highlights the widespread reliance on J1772 by Nissan Leaf and Chevrolet Bolt EV owners for daily charging.
4. Which Vehicles Support J1772 Charging?
Most EVs and PHEVs in North America are equipped with J1772 connectors, including:
• Tesla models (with an adapter)
• Nissan Leaf
• Chevrolet Bolt EV
• Toyota Prius Prime (PHEV)
The broad compatibility of J1772 makes it one of the most popular charging standards in North America.
According to the U.S. Environmental Protection Agency (EPA), over 95% of EVs sold in North America in 2024 support J1772. Tesla’s use of J1772 adapters allows its vehicles to charge at nearly all public AC stations. Additionally, research by Electric Mobility Canada shows that Nissan Leaf and Chevrolet Bolt EV owners highly value the compatibility and ease of use of J1772.
