Electric cars aren’t novel fads anymore. They represent transportation’s future. But did you ever ask how the car and charging station communicate? It’s the EV charger connector. It’s a small but mighty bit of kit that’s the link between mobility and energy. Its absence would mean no charging, no road trip, and no clean energy future.
Here, we will cover all that you might want to know about the EV charging connector. From the variety out there to how they influence charging time, to standards adopted in locations, this is an article that will provide a comprehensive insight. By then, you will also know how Yongrui Energy can be of assistance in selecting a suitable connector for your business or work.
What is an EV Charger Connector and Why Is It Important?
It is an EV charger connector that is the end plug on a charging cable and inserts into the car. It has a corresponding socket on the car side referred to as the vehicle inlet. When plugged in, the connector and inlet establish a secure electrical and data connection. With this handshake, both the car and charger can reach a mutual decision regarding how much power can be utilized and how aggressively it can be supplied.
Think of it like the charger is speaking a language. The connector is the translator, making sure both sides understand each other. Without it, energy cannot move from the grid into your car’s battery.
They make a difference because they control more than physical interoperability. They control charging speed, levels of safety, and even how drivers will interact with charging stations.
Types of EV Charger Connectors That Everyone Should Know
Various places have integrated varying EV charging standards. What that implies is that an EV charging connector that works in a certain country may or may not be able to work in another. Let us unpack these main categories.
Type 1 Connector in North America
Type 1 connector or SAE J1772 is common in North America, used for AC charging. It will usually deliver between 7 kilowatts and 9 kilowatts. Though convenient and universally available, it is not designed for use in three-phase charging and hence limits application beyond North America.
Type 2 Connector in Europe
It primarily makes use of the Type 2 connector or Mennekes connector. It accommodates both single-phase and three-phase charging. That implies that it can provide a maximum level of AC power not exceeding 22 kilowatts in any public charging station.
CCS1 and CCS2 Connectors
It’s a replacement for both Type 1 and Type 2. CCS1 is North America’s version, and CCS2 is Europe’s. They include two additional pins to handle DC charging at a much higher power. With CCS, drivers can achieve charging rates up to a maximum of 350 kilowatts, depending on the charger and vehicle.
Connectors DC and AC GB in China
China uses its own standard, which runs under GB T. It has a version that is designed to work for AC and a version that works on fast charging DC. GB T has a large installation within China’s wide EV network. GB T connectors are commonly used within high-power stations beyond even 200 kilowatts for DC charging.
CHADeMO Connector in Japan
CHAdeMO began in Japan and was part of the original DC fast charging protocols. While it’s currently phasing out in certain locations, it’s still highly adopted in Japan and around the world. CHAdeMO is further notable due to early compliance with vehicle-to-grid technology, enabling cars to supply power to the mains.
NACS Connector or J3400 SAE
Tesla also launched its own connector in North America known as the North American Charging Standard, which is today also known as SAE J3400. The connector is smaller and less complex, and supports AC and DC charging within a single design. Numerous carmakers have since embraced NACS, and hence it has become a powerhouse for tomorrow.
Why EV Charger Connector Types Affect Charging Speed
You can think that charging speed is only reliant on how quickly a charging station is. But a connector does matter a lot, too.
AC charging is dependent on your car’s onboard charger. If your onboard car charger only has a capacity to accept 7 kilowatts, then no matter if you charge it on a 22 kilowatt station, it will charge only at 7 kilowatts.
With DC charging, power is supplied directly to the battery from the connector and charging cable. That’s why DC connectors such as CCS or GB T can supply tens or even hundreds of kilowatts. Even then, though, connector design has limitations. To supply in excess of 250 kilowatts safely, say, a connector and cable will require liquid chilling to prevent overheating.
It’s not merely a matter of shape and size. It regulates how safely electricity can travel and how heat is handled while charging.
Local EV Charger Connection Standards
Each area does things differently with EV charger connectors. If you have overseas projects ahead of you, then knowing these differences is a requirement.
In North America, charging is largely done through the use of a Type 1 connector. DC charging is mainly done using CCS1 and NACS. With most manufacturers going ahead and embracing NACS, North America is converging.
In Europe, AC charging employs the use of the Type 2 connector, while DC fast charging in public charging points demands CCS2. This is one of the most standardized locations in Europe for the connector type.
China uses AC and DC connectors branded GB T. Being the largest EV market globally, China has started tilting towards a new ChaoJi design that will allow even quicker charging in the future.
Japan still uses Type 1 on AC charging and CHAdeMO on DC fast charging. Although CCS is coming into use, CHAdeMO is still dominating.
Choosing the Right EV Charger Connector for Your Application
Choosing a quality EV charger connector is about keeping ahead of trends rather than keeping up. It’s about meeting user expectations and making your investment worthwhile.
Begin at the region level. If your application is in Europe, then Type 2 and CCS2 will be mandatory. In North America, it will likely be necessary to use NACS and potentially CCS1. In China, GB T will be mandatory, while in Japan, CHAdeMO is still used.
Vehicle mix then. What type of EVs will charge out of your chargers? A fleet of van delivery trucks might require night-time AC charging, but a highway rest area will require ultra-fast DC charging.
Thirdly, don’t forget charging speed and environment. If you will be dealing with high-power charging, be sure your connector and cable can be high-current rated and possibly liquid-cooled. And if your chargers will be subject to harsh operating environments, then durability and certification will be relevant.
