In the table below, you can see how the different EV charging connector types compare to each other.What are connectors? Connectors in English grammar are basically conjunctive words that are used for connecting similar elements present in a sentence. How do slow, fast and rapid EV connector types compare? However, Tesla drivers aren’t limited to using the company’s own public charging points - they can purchase adaptors that allow them to connect to other public charging points as well. Tesla owners can make use of Tesla’s Supercharger network, which uses rapid DC charging at up to 150 kW but can only be connected to with a Tesla Type 2 or CCS connector. However, many vehicles could be charged to 80% in as little as 20-30 minutes to an hour. Rapid chargers work with both alternating (which use a Type 2 43 kW connector) and direct currents (these use CCS and CHAdeMO 50 kW connectors).Ĭharging times, again, are variable depending on the vehicle, but it’s worth noting that estimates will usually assume you’re charging up to 80% of the battery’s capacity - charging times slow significantly after 80% in order to protect the battery. The electricity mains supply of most homes and workplaces in the UK cannot support a rapid charger, so they’re most often found at service stations and can only be used on vehicles with rapid charging capabilities. Rapid chargers are by far the quickest way to charge an electric vehicle, but they’re the least commonly available. There are more options available for public charging - slow and fast charging are available, but so is rapid charging. If a vehicle like the Honda e, which has a 6.6 kW onboard charger, is being charged by a 22 kW fast charger, it will only charge at a maximum rate of 6.6 kW. It’s also worth remembering that a fast charger can only charge a vehicle according to the maximum power the vehicle accepts, regardless of how powerful the charger is. Fast charging connector types are available as Type 1 or Type 2.įast chargers can obviously charge EVs quicker than slow chargers, though, again, this will vary depending on the vehicle being charged - a 7 kW would offer up to 30 miles per hour of charging, while a 22 kW could offer as many as 90 miles per hour of charging. Fast chargingįast charging units are the next step up from the slow chargers - they still use an alternating current but are rated usually at either 7 kW or 22 kW (though there may soon be direct current (DC) chargers that use CCS or CHAdeMO connectors which are rated in the same bracket at 25 kW). Slow charging connector types are available as Type 1, Type 2 or a three-pin plug.Ĭharging times naturally vary depending on the EV, but they could range from six to twelve hours to charge fully. It is usually listed as having a charge rate of up to 3 kW, though charging can be carried out at anywhere between 2.3 kW and 6 kW. Slow chargingĪn AC slow charging wall unit is commonly used at home to charge electric vehicles overnight, though they can also be found in workplaces and public charging stations. You can see more connector types in the table below. You can buy Type 1 and Type 2 connectors for both slow and fast charging - Type 1 cables have five pins and Type 2 cables have seven pins, so a Type 1 cable for slow charging would have five pins but a charging rate of up to 3 kW, while a Type 1 cable for fast charging would have five pins but a charging rate of 22 kW. This allows them to plug into most charging points, whether they’re at home or on the go. Most EVs are supplied with two cables: one for slow charging and one for fast charging through AC charging units. That’s why it’s recommended that electric car owners install a dedicated wall charger for use at home.Įlectric cars will be fitted with either a Type 1 (if it’s an older model) or the more common (particularly for European-made models) Type 2 connector. It’s possible to charge an electric car using a standard three-pin plug that you’d use to plug any appliance into the mains supply, but this is a very slow way of charging a car. When charging at home, it’s highly likely you’ll be using an alternating current (AC) connector. In practice, it’s a case of plugging one end into the charging point and the other end into the car, and then you can track the charging progress on your phone or in the car itself. You therefore need to think about the connection the vehicle needs, and the connection the charging point (whether it’s at home or out and about) needs. Phone charging cables will have a connector at one end for the plug (like a USB) and a connector at the other end for the phone. The easiest way to think about charging an EV is in terms of charging a phone.
