Electric Vehicle Charging Connector Types and Speeds
What electric vehicle charging connector types are there and which ones are the fastest at charging? We'll answer this question in this article.
Electric vehicles (EV) can charge in as little as half an hour or in as much as 12 hours. While always more cost-effective than a full tank of gas on a traditional car, ensuring the best charging rate for your EV means taking a closer look at the different electric vehicle charging connector types and speeds, as well as the charger type and the size of battery your car is equipped with.
Here, we’re going to cover the different kinds of electric vehicle connector formats and what kind of charging speeds you can expect from them.
Vehicle side EV connectors
These types of EV charger connectors are used for charging at home, work, and other places that have a standard three-pin power outlet. There are slow and fast charging varieties available, and they charge by alternating current.
Type 1 (5-pins)
This type of connector uses a standard US socket, with no locking mechanism and carries only single-phase power. Their typical power ratings are 3.7kW and 7kW. This means that they can offer an average rate of charge that’s around 12.5 miles per hour or 25 miles per hour, respective to the different power ratings.
Type 2 (7-pins)
The other variety of vehicle side EV connector fits the standard European socket format. It has an inbuilt locking mechanism and can carry three-phase power. There are three typical power ratings for these connectors: 3.7kw, 7kw, and 22kw (which is the three-phase version). This means that they have a respective approximate range per hour charge rate of 12.5 miles, 25 miles, and 75 miles.
Vehicle side rapid charging EV connectors
These connectors are used for accessing direct current charge points, and there are three main varieties.
The original variety of rapid charging DC connector and still the most commonly found type in the UK. CHAdeMO connectors have a typical power rating of 50kW and have an approximate charge rate of 75 miles per hour.
Combined Charging System
Also known as CSS, for short, these high-power connectors are likely to become a lot more popular in future, partly due to the power and also due to the neat arrangement of Type 2 pins. They have three typical power ratings of 50kW, 150kW, and 350kW. This offers a charge rate of 75 miles per hour, 225 miles per hour, and 525 miles per hour, respectively.
Type 2 (7-pins)
Much like the standard Type 2 EV connector, this is a standard European format, but right now only Tesla Superchargers offer DC power via Type 2 connector. The charge rate is throttled when charging, but the maximum charge it can offer is 130kW, which translates to roughly 180 miles per hour of charging.
ChargePoint side AC EV connector types
Just as your car will have an EV connector, so too will the ChargePoint. Finding out what your actual maximum charge rate will mean looking at both and seeing the lowest of the two maximums. These AC charge connectors are used at home, work, and public spaces. You can find a ChargePoint near you using the ChargePoint Map from their official website.
Type 2 (7-pins)
This is the universal socket that you’re going to find in the vast majority of places, just like the USB is considered the universal socket for digital devices, even if their cables are different. They come with two typical power ratings, a 7kW single-phase connector and the rarer 22kW three-phase connector. The 7kW connector has an average charge rate of 25 miles per hour. The 22kW connector has an average charge rate of 75 miles per hour.
These can be used as an emergency backup when a type 2 connector isn’t available, but it’s not recommended as they are slow charging. They have a typical power rating of 2.3kW which translates to a charging rate of 8 miles for every hour spent charging.
Chargepoint side rapid charger connector types
Since DC rapid chargers have their own tethered cables to match the car-side connectors, there aren’t any ChargePoint-side DC sockets to consider.
The type of charging connector varies from vehicle to vehicle, as well as by the power rating of the ChargePoint. When it comes to understanding the maximum charge rate and, thus, the charging efficiency of the vehicle, the connector plays a key role. Make sure that you know which charging connectors you’re using, what their power rating is, and what range you can expect per hour of charging. It will help you get a better understanding of how much power you’re actually getting while charging your car up.
If you're interested in owning or trying out an electric vehicle for a short period of time, why not lease one? It's affordable and you can give the vehicle back after 2 years (depending on your contract) if you decided it wasn't a long term option for you. You can find our available models of electric cars to lease here.
