It won’t be wrong to state that your next vehicle will be an EV. But are you aware of the different types of charging ports that charge an EV? Well, you don’t need to worry. By the end of this blog, you will have sufficient knowledge about EV charger plug types to choose your next drive and transition to cleaner energy solutions.
According to a study by Gartner, an estimated 85 million EVs will be on the road by 2025. Year-on-year, this will mark three times sales growth compared to 2024. These stats shouldn’t come as a surprise, as by the end of the decade, more than 30% of all vehicles on the road will be battery-powered and help put major curbs on vehicular pollution. Compared to China and the European Union, the United States, one of the laggards in the EV space, is seeing a surge, with one out of five vehicles sold being an EV.
As you add an EV to your bucket list, understanding the infrastructure that supports these cars—specifically the EV charging plug is important to make the right choice and have a seamless ownership experience. Unlike ICE (internal combustion engine) vehicles that you drive to a gas station for fuel top-up, the most important aspect of owning an EV is knowing how and where to charge it. It is where understanding different types of EV charging plugs is important.
Why Are There Different Charger Types?
At this juncture, you might have the most legitimate question doing the rounds on your mind. Why are there different types of charging ports? Aren’t EVs a recent phenomenon, and should there have been standardization in a globalized world? The answer to this question is a bit complex as automakers worldwide developed this technology almost simultaneously, often accommodating diverse vehicle designs, regional standards, and charging requirements.
Hence, we have different EV connector types that dominate in certain geographies. It’s like the railway gauges of the 18th and 19th centuries, where different countries and empires chose a different gauge!
We now have a scenario where there are different types of plugs for EV charging in the United States. Hence, you must know about EV charging plugs to easily access charging stations or build your home charging infrastructure. As an EV owner, you must avoid a scenario where you own a vehicle that lacks charging infrastructure across the country. Let’s explore the most common EV plug types in the United States and discuss their unique features to help you stay powered on the go.
AC & DC Chargers
Before we delve into the different types of charger plugs used in the United States, it is important to note that the chargers are broadly classified into two categories – AC (Alternating Current) and DC (Direct Current) based on the type of power they deliver. AC chargers, commonly used in homes and workplaces, provide slower charging as the vehicle’s onboard converter converts AC to DC for battery storage. They are ideal for overnight or long-duration charging.
On the other hand, DC chargers bypass the vehicle’s converter, delivering power directly to the battery for significantly faster charging. Most public charging stations have DC fast chargers, enabling rapid charging within minutes, making them perfect for long-distance travel or quick top-ups. AC chargers are more cost-effective, but DC chargers offer speed and convenience.
Type 1 Charger
The J1772 plug, more popular as the Type 1 plug, is among the most popular charging plugs in the United States. It is compatible with most types of EVs sold in the country, including plug-in hybrids. It is also known as the J-plug for its distinctive design and comes with a 5-pin design. These are standards for Level 1 (120V) and Level 2 (240V) charging stations. You will see them both in the home and the public infrastructure.
It’s simple architecture makes home charging convenient, explaining its overwhelming popularity among EV users. They have a maximum power output of 19.2 kW but lack fast charging capabilities. These are ideally used in homes for overnight charging and can meet the needs of most EV owners.
Combined Charging System Type 1
The Combined Charging System, or the CCS plug, is an incremental enhancement over the J1772. It is a step up over the Type 1 charger because it supports both AC and DC fast charging. It has a seven-pin plug type with two more pins that offer DC fast charging capabilities. While most American and European EV models are compatible with these charging plug types, many entry-end EVs don’t support DC fast charging.
This type of charging plug is mostly seen in public charging stations and offers quick top-up for vehicles, which is ideal to extend the range during long trips. Depending on the model of the vehicle, it can top up a vehicle from 0 to 80% in 30 minutes.
CCS Type 2
CSS Type 2 chargers are not predominant in the United States but are primarily used in Europe. In this type, you have a Mennekes type 2 plug with two additional high-speed charging pins. Hence, it supports both AC and DC fast charging, offering Level 1, Level 2, and Level 3 DC fast charging capabilities that can juice up an EV quickly, helping owners overcome any form of range anxiety during long trips.
It can offer a maximum power output of 360 kW, good enough to power the biggest EVs. As mentioned earlier, this charging plug isn’t very popular in the United States, and you aren’t likely to use it.
CHAdeMO
CHAdeMO is a fast-charging standard developed in Japan and made popular in the United States by Nissan. However, like CSS Type 2, you won’t see them in most public charging stations in the United States, though some offer it for the older generation of EVs that use this charging outlet.
The unique thing about CHAdeMO plug types is that they allow bi-directional charging, which means that vehicles can discharge their power back to the grid or pass it to another vehicle in need.
Tesla Charger Plug
If the Japanese can have their charging standard, how can Elon Musk have something generic for his line of EVs? The Tesla charging plug type is fast becoming the standard in the United States. Officially known as the North American Charging Standard after Tesla opened the proprietary charging connector to the world, it is the fastest-growing electric car plug type in the United States.
It has gotten a big boost due to Tesla’s initiative to build a large-scale charging outlet network in the United States and beyond. With a maximum output of 250 kW, it can quickly charge big batteries, offering the EV owners complete peace of mind.
To sum up, we have discussed the different types of plugs that EVs use in the United States above and offered you basic insights into different EV charging plugs you need to know. As the EV market grows globally and different automakers develop their vehicles, new charging types may make inroads into the US market.
As a potential EV owner, you must choose a vehicle that considers the presence of charging infrastructure in your vicinity and across the nation to drive your EV carefree and top up the battery during your long trips
