Electric vehicle (EV) charging station networks have grown in recent times, however navigating the different sorts can get complicated. Right here we’ll clarify varieties 1, 2, and three, their connector plugs, and what conditions they’re greatest for.
What Forms of EV Charging Stations Are There?
There are three varieties, or “ranges,” of EV charging stations accessible as of this writing: kind 1, kind 2, and kind 3. Sort 1 is the slowest, whereas kind Three can cost an EV’s battery a lot of the means in about an hour.
Earlier than we dive in, we must always evaluation some phrases. Charging stations are referred to as by a number of names, all of which imply the identical factor, which might add to the confusion about which one to choose. For instance, a sort 2 station is also referred to as a “degree 2” station. It nonetheless has the identical energy output and means the identical factor. Different frequent phrases for charging stations embrace:
- Charging outlet
- Charging plug
- Charging port
- Charger
- EVSE (Electrical Car Provide Gear)
All of those imply the identical factor. What’s vital to search for is which kind (or degree) the station is, since that’s what’s going to let you know its energy output and what connector you’ll want to use to plug in.

Sort 1 Chargers: Your Fundamental Wall Plug
Sort 1 chargers are simply common wall shops, the identical factor you’d plug your cellphone into to cost. As you would possibly anticipate, it takes a really very long time to charge an EV’s battery with a sort 1 charger — about 20 hours for a 120-mile cost.
Sort 1 chargers use AC (alternating present) energy, and vary in output from 1kW to 7.5 kW. They’re additionally referred to as “single-phase” plugs, and kind 1 connectors are customary for EVs made within the U.S. and Japan.
This kind of outlet is just too sluggish for usually charging an EV at residence, even in a single day, however might be good for automobiles with smaller battery packs like plug-in hybrids. That stated, it’s best to nonetheless attempt to use a sort 2 or Three charger each time you possibly can.
All EVs are bought with a cable adapter that lets them use degree 1 chargers (wall shops) and a separate cable with a J1772 adapter to be used with degree 2 charging stations. Teslas use their very own proprietary plug for his or her chargers but additionally include an adapter, permitting Tesla drivers to make use of degree 2 public charging stations outdoors the corporate’s community.
Sort 2 Chargers: Discovered at Most Public Charging Stations
Sort 2 chargers additionally use AC energy and permit for elevated charging velocity as a consequence of their elevated energy output. These chargers ship round 240 volts of energy and may cost an EV battery wherever from 5 to seven occasions quicker than a sort 1 charger.
Sort 2 chargers use a special kind of plug to attach than a sort 1 charger as a result of they require a connector plug with extra wires to hold the extra energy. That plug is known as an SAE J1772 connector and is the usual for all EVs produced in North America as of this writing. Many EVs bought at present come packaged with some form of J1772 connector. In the event that they don’t, you possibly can normally purchase one on-line from the producer.
Sort 2 chargers may also be put in in-home for quicker charging with out reliance on a public station. It may be costly, however drastically reduces the trouble of at-home EV charging. The velocity of an at-home kind 2 charging station will depend upon which charger you get put in and your native energy grid, amongst different components, however you possibly can nonetheless anticipate the identical cost time as a public kind 2 charging station.
Sort Three Chargers: The Highway Journey EV Charger
Sort Three chargers, also referred to as DC quick charging or DCFC chargers, will get you the quickest juice-up of any charging station on the market. They use DC (direct present) power, and require particular plugs to attach which can be completely different from the J1772 customary. There are three varieties of connector plugs that work with kind Three charging stations as of this writing:
- CHAdeMO: created by a totally completely different firm than those that set the SAE requirements, and due to this fact use a special plug building.
- SAE Combo (additionally referred to as CSS, combo charging system, or simply “combo”): an SAE customary connector that mixes a smaller J1772 plug with a DC connector to ship additional energy.
- Tesla connector: works with the corporate’s kind 2 charging community and its kind Three Supercharger stations.
A sort Three charging station can get an EV’s battery to across the 80 % mark in roughly half an hour. Whereas nonetheless fairly a bit longer than a typical gasoline fill-up, these chargers are the most suitable choice accessible for longer journeys the place you could have to cost the battery shortly, like cross-country drives. Their energy output is usually between 20 and 50kW, delivering the equal of 3-20 miles per minute of charging time. You’ll discover kind Three charging stations alongside main highways at locations like eating places and standard gasoline stations, as that’s the place they get probably the most use. They’re additionally turning into extra accessible in public garages and office parking tons.
Whereas these chargers are the quickest, in addition they carry the very best per-minute cost of any of the three varieties of EV charging stations. Charging up with one among these will normally run you about the identical value as a tank of gas.
Until you’ve some huge cash mendacity round, you in all probability gained’t be capable of set up a sort Three charger at residence, as they’ll value hundreds to place in. Nevertheless, a degree 2 residence charger is greater than sufficient for nearly any EV driver.
So, Which Sort of Charger Ought to You Select?
Which kind of charging station you employ will depend on your automobile and wishes. You’ll want to contemplate proximity, the quantity of driving you do, and the way a lot time you must cost. Whichever one you choose, remember the fact that it’s going to take some time. You’re higher off plugging in earlier than you go sit all the way down to eat at a restaurant or at the start of a workday, for instance, since you possibly can let the automobile sit for the time it must energy up.
All three charging station varieties could be viable. In the event you personal a plug-in hybrid that has a small battery pack, kind 1 charging might be all you want. For all-electric automobiles, kind 2 and three might be what you employ most of if not on a regular basis. For the standard EV proprietor, together with Tesla drivers, degree 2 charging stations would be the most plentiful and handy to make use of, particularly if you will get a degree 2 residence station put in. Stage Three stations are good for fast top-ups and to recharge on lengthy journeys, as they supply the quickest fee.
