Electric vehicles (EVs) are surging in popularity as countries aim to reduce emissions and consumers look for alternatives to gas-powered cars. However, not all EVs use the same type of connector for charging, and the connector differs across countries and regions. This can cause issues when driving EVs across borders if the appropriate charger connector is unavailable.
In this guide, we’ll provide an overview of the leading EV connector types used in different countries. Understanding the predominant connectors in various markets can help EV drivers better prepare for long-distance travel and avoid getting stranded without a compatible charger.
International standardization is still a long way ahead, so understanding the connectors used in each region helps ensure hassle-free charging for EV drivers wherever they are.
EV Charging Levels and TechniquesBefore delving into specific connector types, let’s first discuss the various levels of EV charging. Then we will discuss the specific connector types according to the different regions. Charging can broadly be divided into three main levels based on voltage and power delivered:
Level 1 ChargingLevel 1 charging uses a normal 120-volt AC outlet, like the ones you have at home. It provides the slowest charging speed, adding about 4-5 miles of driving range/ hour of charging time for a typical electric vehicle.
Level 1 works well for overnight charging at home when you don’t need to be in a rush. The great thing about Level 1 is that it doesn’t require any special equipment other than the standard charger cord that comes with your EV. So Level 1 offers an easy and convenient way to charge up if you have the time to wait.
Level 2 ChargingLevel 2 bumps the voltage up to 240 volts and uses dedicated charging equipment. Depending on the EV and charger specifications, it can add 25-50 miles of range per hour. A Level 2 charger is most suitable for home use, and you’ll also see it at most public charging stations. However, we need special EV connectors that can handle higher voltages and currents.
DC Fast ChargingAlso known as Level 3, DC fast charging provides the fastest replenishment by converting AC power to DC before feeding it to the vehicle battery. Currents are much higher at 50kW-350kW or more. Using a DC fast charger, you will achieve an 80% battery top-up within half an hour or less. However, DC fast chargers are incompatible with home installation, and you’ll only see them commercially along busy corridors.
In summary, while Level 1 charging is convenient, higher power options like Level 2 and DC fast charging are better for quicker refueling on busier days.
Now, let’s explore what connector types major markets use to support the various charging levels.
EV Charging Connectors by Country
SAE J1772 (Type 1) Connector – Level 1 and Level 2 ChargingThe J1772 connector is the most widely used plug for electric cars in the United States and Canada. It was designed by SAE International to enable safe and reliable charging. The J1772 works for both slower Level 1 charging using a regular wall outlet and faster Level 2 charging which needs a 240-volt outlet. It has handy features like pilot and proximity pins to prevent the cord from being unplugged mid-charge.
Most new electric vehicles sold in the US and Canada will have a J1772 port built-in, ready to connect to either Level 1 or Level 2 charging. You’ll see these connectors on many public charging stations too. So if you’re new to EVs, just remember – if you see a J1772, you’re all set to charge up! It’s the standard plug that makes EV charging simple across the US and Canada.

CCS Combo 1 – DC Fast Charging
The Combined Charging System or “CCS” specification is the standard in North America for DC fast charging. Its design is similar to the Type 1 connector’s design but incorporates additional pins for high-voltage DC power transfer. Moreover, it also supports backward compatibility with AC charging.
Nearly all new EVs presently available in North America support the CCS Combo 1 standard for DC fast charging along major roadways and in populated areas. Wide adoption of this standard has accelerated the expansion of DC fast charging infrastructure by reducing equipment costs and simplifying the system for car owners and station operators. The CCS Combo 1 leaves the other charging standards in the dust by providing EV charging at speeds exceeding 350kW.
CCS Combo 1European Connectors European charging standards are distinct from the US and Canada yet compatible with AC and DC power delivery.
IEC 62196 Type 2 – AC Charging
The Type 2 plug, defined by the international specification IEC 62196, has become the standard connector for Level 1 and 2 AC charging charging throughout Europe. Manufactured according to the “Mennekes” design, the Type 2 connector supports up to 400 volts and currents exceeding 32 amps for single-phase charging at a maximum of 22kW power.
Most new passenger EVs sold in Europe have Type 2 charging ports validated under rigorous IEC testing standards. A vast, ever-growing public charging infrastructure relies on this interoperable AC charging standard, facilitating convenient long-distance EV travel across cities. The availability of Type 2 charging has strengthened Europe’s position as a top market for EV adoption in recent years.
IEC 62196 Type 2Combination Charging System (CCS) – DC Fast Charging
For DC rapid charging, Europe selected the Combined Charging System interface as its standard, much like in North America. However, the physical connector design revolves around the IEC 62196 Type 2 connector rather than SAE’s “Type 1” due to differences in electrical grids and outlets between the two regions.
European CCS referred to as “Type 2 CCS”, merges the European Type 2’s standardized AC charging function with additional DC pins to deliver high-power quick charging. Similar to the North American CCS, it offers full forward and backward compatibility.
Despite some differences in charging station designs, the Type 2 CCS standard makes it easier for European EV owners to charge their cars, even when traveling across borders.
CCS 1 (North American Standard) vs. CCS 2 (European Standard)Chinese Charging ConnectorsChina’s National Standards Organization has developed and exclusively implemented its own standard for electric vehicle charging called the “GB/T” connector standard.
GB/T Connector – Chinese Standard Connector
The GB/T charging connector closely resembles the physical design of Europe’s IEC 62196 Type 2 connector but has differences in cabling and pin assignments inside. It is only compatible with AC Level 1 and Level 2 charging in China.
Nonetheless, the GB/T standard has enabled China to rapidly build a coherent nationwide public charging infrastructure and establish centralized control over electric mobility development without competing connector types. In 2020, over 25% of all the electric vehicles sold worldwide were in China. This shows that China’s GB/T charging interface has been an effective approach for the world’s largest auto and EV market.
However, China is now working to make its connectors compatible with the CCS standard used in other major markets. It supports Chinese automakers’ global expansion goals, riding on strong domestic EV growth underpinned by the widespread GB/T standard. While the GB/T connector works well in China, adding CCS compatibility will help Chinese EVs compete and charge quickly in international markets.
GB/T ConnectorJapanese Charging StandardsJapan uses the CHAdeMO standard for DC fast charging to kickstart the transition to electric vehicles nationwide.
CHAdeMO Connector
CHAdeMO, which stands for “CHArge de MOve,” was jointly developed in 2010 by major Japanese automakers like Nissan, Mitsubishi, and Tokyo Electric Power Company. Unlike more versatile global standards, CHAdeMO only provides DC power for quick charging.
Japan initially focused on DC fast charging along highways because early EV batteries had limited range. In the early 2010s, CHAdeMO could charge up to 50kW faster and had more charging stations than alternatives. This made it the top quick-charging solution in Japan and parts of Asia.
However, CHAdeMO’s market share is now declining as the globally compatible CCS standard expands with even faster charging capabilities. As EV technology continues improving worldwide, adapting to newer standards appears critical for Japanese automakers to remain competitive. Industry cooperation will be key to smoothly transitioning from CHAdeMO to globally dominant interfaces like CCS.
CHAdeMO ConnectorTesla’s Unique ConnectorAs an early entrant to EVs, Tesla developed its unique charging plug design, the “Tesla Connector” globally across its vehicle lineup.
Tesla Connector
Tesla uses its unique High Power Connector for charging, which is larger than most standard plugs. Using the built-in charger, it can deliver over 100 amps for ultra-fast charging above 250kW DC or up to 48 amps for 11kW AC. The connector has extra pins to enable liquid cooling at such high power levels.
However, Tesla owners can’t access public charging stations built for domestic standards like CCS or CHAdeMO in many countries. To address this, Tesla provides adapters so its cars can charge on standard regional networks using third-party equipment overseas.
Tesla’s proprietary connector sets it apart but also risks technology lock-in and less accessibility versus universal connectors. As Tesla expands globally, it may need to accept cross-compatible chargers even if that means sacrificing some unique advantages of its custom interface, like ultra-fast charging rates. The key is to find the right balance between proprietary technology and global compatibility.
Tesla Proprietary ConnectorStandardization EffortsSeveral ongoing initiatives aim to further align EV charging standards worldwide over the long run.
Combined Charging SystemThe Combined Charging System (CCS) is being promoted as the global standard for fast DC and AC charging by automakers, governments, and even China. Having one common connector instead of proprietary or regional ones could speed up building charging stations globally and lower costs.
However, widespread CCS adoption faces challenges from existing regional connectors people are used to, as well as technical transitions.
The International Electrotechnical Commission (IEC)The International Electrotechnical Commission (IEC) is leading the coordination of technical standards between countries through its TC69 committee. It develops guidelines many regional standards are based on, like the IEC 62196 specification
The CharIn ConsortiumThe CharIn Consortium is an industry alliance working to establish one universal EV charging standard worldwide. It advocates for CCS adoption by collaborating with automakers, utilities, charging companies, and governments.
China’s RoleAs the largest EV market, China transitioning from GB/T to CCS compatibility could significantly advance global harmonization efforts. Chinese policymakers and vehicle/equipment makers are gradually embracing CCS in addition to GB/T. This reflects national ambitions for exporting automotive technology on a global scale.
Regional CoordinationRegional groups like the EU and USMCA are also driving unified charging standards among member countries. This shows political momentum towards a global charging framework.
Conclusion:Establishing universal EV charging standards remains a work in progress as electric vehicles continue gaining popularity worldwide. For now, different regions rely on distinct connectors like CCS, CHAdeMO, GB/T, Tesla’s proprietary plug, and more.
While this fragmentation poses some headaches for cross-border EV travel today, collaborative efforts between automakers, governments, and standard bodies may achieve global harmonization over time. One unified fast-charging standard could emerge within the next decade with continued coordination. This would accelerate EV adoption by maximizing charging accessibility for drivers everywhere.
