EV Charge Connector Types: CCS vs CHAdeMO Explained

Link to Ruihua

Electric vehicles (EVs) are on the rise, and with that, understanding the various types of charging connectors available is essential for any EV owner. Among the most popular DC fast charging standards are the Combined Charging System (CCS) and CHAdeMO. This article will explore the differences between these two connector types, along with relevant statistics to help you make informed decisions.

What Are CCS and CHAdeMO?

Both CCS and CHAdeMO are fast-charging standards for electric vehicles but have notable differences in design, compatibility, and usage.

CCS Overview

The Combined Charging System (CCS) allows for both AC and DC charging. It incorporates a Type 1 (in North America) or Type 2 (in Europe) connector for AC charging, and adds two additional pins for DC fast charging. This flexibility makes CCS one of the most widely adopted charging standards in the world.

According to the International Energy Agency (IEA), around 46% of all global fast chargers were CCS-compatible as of 2021, showcasing its popularity.

CHAdeMO Overview

CHAdeMO is an older standard, developed in Japan. It primarily focuses on DC fast charging, using a unique connector. CHAdeMO is known for its user-friendly approach, allowing the vehicle to communicate with both the charger and the energy supplier, which can enhance overall energy management efficiency.

As of 2021, CHAdeMO accounted for approximately 24% of the global DC fast charger market, according to IEA statistics.

Key Statistics on CCS and CHAdeMO Usage

Market Trends

As the EV market continues to grow, the demand for effective charging solutions is on the rise. The following statistics illustrate market trends:

• By 2022, approximately 52% of all fast charging stations installed worldwide were compatible with CCS.
• CHAdeMO's presence has seen a decline from about 30% in 2019 to 24% in 2021, indicating a shift towards CCS dominance.
• The global EV sales were expected to exceed 6.5 million units in 2021, leading to increased demand for both types of charging infrastructure.

Compatibility

It's crucial to consider vehicle compatibility when choosing between CCS and CHAdeMO:

• CCS is used by major automakers, including BMW, Ford, Volkswagen, and Hyundai.
• CHAdeMO is primarily adopted by Japanese manufacturers, such as Nissan and Mitsubishi.
• As of early 2022, around 76% of all EVs sold in Europe were equipped with CCS, while in Japan, CHAdeMO still retains a larger share.

Charging Speed Comparisons

Power Outputs

Both standards offer varying power outputs, impacting charging speed:

• CCS supports charging rates up to 350 kW, with charging times of up to 80% in just under 30 minutes.
• CHAdeMO offers charging rates up to 200 kW, providing an 80% charge in about 40 minutes in ideal conditions.

Adoption by Charging Networks

The growing charging infrastructure influences user experience and convenience. Notable charging networks include:

• CCS: Networks like Electrify America and Ionity primarily support CCS.
• CHAdeMO: Networks such as EVgo have included CHAdeMO ports, but they are increasingly adopting CCS as well.

Future Outlook

The shifting landscape of EV charging technology is impacted by various factors:

• Government regulations and incentives promoting EV adoption.
• Technological advancements leading to faster and more efficient charging solutions.
• The potential for interoperability between different charging standards, which may ease the transition for users.

In summary, CCS is becoming the preferred choice for many manufacturers and charging stations due to its versatility and faster charging capabilities, while CHAdeMO still holds a significant share in specific markets, particularly in Japan. Understanding these options allows EV owners to make informed decisions about their charging needs.
