Slow, fast, and faster: to charge electric cars

note: This article has edited to reflect updated on the Nissan Leaf.

One advantage of cars comes from the available infrastructure: We have plugs just about There are many more plugs than even stations.

So charging an electric car be easy; just plug it the nearest outlet.

And it is that almost. Your standard outlet in the US offers 120 volts of current (AC), with a breaker rated at 15 or 20 amps. electric cars I have come with a cable for that outlet, a grounded plug on one end and a J1772 SAE electric-car-charging on the other.

The J1772 plug was designed for electric car charging.

is, given a typical electric car the Nissan Leaf. it can take 15 to charge the battery from to its EPA-rated 75-mile range that standard household

If you want to add more juice in a amount of time, there are a of options. A Level 2 charging plugs into the car’s port, draws 240 volts 30 amps current, and can take the from 0 miles to full in 4 hours if the car is equipped with the 6.6 kilowatt onboard charger. The option is a DC fast charger, called Level 3, drawing 480 which takes the Leaf 0 to 80 percent of its charge in about 30

These charging options are high-tech than a simple outlet. The plugs include for data, letting the charger with the car. This channel lets the car tell the how much electricity it wants at any time during the charging helping preserve battery and prevent overheating.

Note I’ve been hedging the here quite a bit. are a lot of factors that affect vehicle charging, such as temperature and the quality of the electricity Charging times will depending on these conditions.

2 charging

The majority of public are Level 2 chargers. You find in special electric-vehicle parking in garages and other facilities. The Web site shows an extensive of charging station locations the country.

Some of these stations cost money on amount of time, some per of electricity, and some are completely to use. However, most are run by a system network, such as or SemaConnect. You may need an account the charging network to use the station.

Plugshare’s web site and app offers on cost and network requirements.

the 8 hours it takes to charge a car as the Nissan Leaf to full one of these stations is probably than you would spend or having lunch nearby, that you probably won’t with a completely dead The 10 extra miles of range you get plugged in might be just to combat range anxiety.

makes this Level 2 station, which easily into a home s garage.

More importantly, you can get a 2 charger installed in your The electricity needs of this of charger are similar to that of a home appliance, such as a dryer. If your home’s can handle the dryer, it should be to handle the charging station.

electric-vehicle makers partner charging-station makers, and offer to get them installed in your For example, Ford offers a charging station sporting the brand. with an installation by AeroVironment.

Home improvement and stores also sell 2 electric-vehicle charging stations. Depot, Lowes, and Best Buy all offerings from manufacturers as Siemens, GE, and Eaton. Depending on home wiring, installation can be as as hanging the charging station on the and plugging it into a 240 volt

Your electric car likely has the to control at what time it You can park the car, plug it in, but the actual charging set for the middle of the when electricity rates are Every morning, your car have a fully charged with maximum range and to go.

Level 3 charging

Now things get a bit as there are competing standards for 3 or DC fast charging. First, the draw of a fast charging is so high that very few are likely to support one. need a 480-volt source can support current of 125 amps, a that will dim the lights in an residential neighborhood.

These are meant for a quick recharge you are out and about. And the reason they only charge a car up to 80 percent is an design to protect the battery, can lose capacity from type of charging.

Many Leafs include two charging one J1772 and one CHAdeMO.

Nissan Leaf and i-Miev owners will be with the CHAdeMO plug. a developed and favored by Japanese and the Tokyo Electric Power The CHAdeMO plug is a sizable of equipment, and requires a separate in the car. The Leaf puts its and CHAdeMO ports side-by-side in of the car, while the Mitsubishi has J1772 and CHAdeMO ports on side of the i-Miev.

CHAdeMO’s big advantage at this of the game is that it can boast the number of cars on the road and stations. Counting against it is the industrial-looking plug, requirement for a charging port, and its name, does not lend itself to spelling or pronunciation.

A competing DC fast charging just beginning deployment is J1772 Combo. From a standpoint, the Combo standard more elegant than as it merely adds two pins to the plug. The same port in the car can for Level 2 or Level 3 charging, the using the same J1772 for data communication, and the extra two for the high-amperage DC current.

As of this only two cars, the Chevy EV and the BMW i3. have J1772 Combo and capability. Likewise, the only Combo station you are going to is in San Diego. German and US automakers are toward the Combo standard, and the for only one charging port in the car is a big

Whether Combo deployment can up to CHAdeMO remains to be seen.

Having developed its own charging Tesla is a bit of an outlier. The proprietary for the Model S has a slim design more elegant than the standard. The nice thing Tesla’s charging system is the plug supports everything a household outlet AC trickle to the Falls flow of electricity one of Tesla’s Superchargers. special charging stations that work for the Model S.

Tesla offers customers its own of Level 2 charging for the home.

The proprietary nature of charging system is problematic for the of electric cars as a whole, in it further fragments charging However, Tesla provides for the J1772 plug, 240-volt plug, and standard 120-volt plug, letting Model S use public Level 2 stations. The S won’t be compatible with CHAdeMO or Combo stations, Tesla can come up with an for those types of plugs.

to a standard wall outlet, the S only gains 3 miles per of charging time. Reaching its 265 EPA-rated range would 88 hours from that Tesla offers a wall that installs on a home’s circuit, its own version of Level 2 that gives the standard S 31 miles per hour of charging.

For Ses equipped with two onboard that capacity goes up to 62 per hour.


Tesla calls its of a Level 3 charging station the a high-current, high-amperage source plugs into the Model standard charging port. A station can fill up the battery of the S entirely in an hour.

One plug to rule them all

have worked together on in the past for the benefit of not only the but consumers. Think wheels, for which in most cases can be from car to car, size due to standards in the lug-nut pattern. for Level 2 charging, has become an standard for most automakers.

3 charging may be a harder standard to as the CHAdeMO group has become entrenched while other seem pretty keen on Combo.

Either way, as technology improves, allowing energy density and thereby range for electric cars, a fast charging standard be needed, along with a of charging stations to support the amount of time that cars will need to up.
