Just Plug it In?
Charging an electric car or electric vehicle (EV) might well seem mysterious to the uninitiated, so we’ve set out here to simplify the charging process. Just like charging your smartphone, at first blush the car just needs to be plugged in.
There are three levels of charging that, in effect, move from slow to fast. They are aptly named Level 1, Level 2 and Level 3. The first two levels can be done at home, and descriptions of all three are next.
Opportunities to Charge at Home
Level 1: This level requires only a standard 110V/120V plug found in your home or apartment. A grounded adapter, like the one shown to the right, will have been supplied with the car. Charging at Level 1 adds 3 to 4 miles of range per hour of charging.
Level 2: This level requires can use a standard 220V/240V outlet, like one you may have available for a household clothes dryer and adds range at 15 to 20 miles per hour of charging. This is a superior option easily “filling” your car overnight and the adapter, likely supplied with 
the car, is shown to the right.
However, we recommend having a charging station set up at your home as there are many tax incentives available that can be taken advantage of. The stations will allow for additional programming to take advantage of lower electricity rates. The car itself can likely do this as well, but the station set up will avoid the hassle of unplugging an d plugging in your dryer over and over.
Note that there are public Level 2 chargers available in some municipalities intended for shoppers or restaurant goers to charge while shopping or eating. They might even be free. The results will only be 20 to 30 miles of range added in most cases.
Fast Charging On the Road
Level 3: This is fast charging public networks using direct current (DC) and is not something available for set up at home. These stations can add up to 600 miles of range per hour of charging depending on both what the car will allow and what the charge station can supply! Further, the chargers are specifically tied to charging standards set by manufacturers, but in the majority of cases, you will spend roughly 30 minutes charging to 80% charge. Please follow this link to learn why you should actually stop there!
There are three standards: Combined Charging System (CCS), CHAdeMO (CHArge de(for) MOve(ing)), and North American Charging Standard (NACS). We’ll ignore the second one, which was developed in Japan, and you should as well in deciding on a purchase as it is used by only a handful of manufacturers, has only a small charging network, and is being superseded. Due to simplicity, lighter weight cabling and extensive network, the NACS standard, a Tesla creation, is slowly being adopted by nearly all auto manufacturers selling vehicles here in the U.S. However, be absolutely sure the connectors on the car are correct if you choose something other than a Tesla and wish to use its network.
The CCS standard does have a significant and useful charging network from a number of suppliers, most notably Electrify America and EVgo, and is used currently by the majority of non-Tesla auto manufacturers. There is no reason to shy away from a vehicle using these Level 3 chargers. Some Tesla stations have been 
adapted to charge CCS-equipped cars as well, but they are few and far between currently. Finally, the CCS network will also be transformed to handle the NACS standard.
Just know that the vast majority of us do only local driving and the easiest and most efficient means of charging is with a Level 2 station set up at home, like the one seen to the right. You’ll never need to pump gas again, never be overcharged for an oil change again, and will always leave home with a full “tank”!
