Installing a Car Charging Station in Your Home – Atlanta Metro Area
Car charging stations require a dedicated circuit. This means they need a power source that has it’s own breaker connection inside of your electrical panel. This is important not only for safety, but it also allows you to specify the amperage of the outlet.
A general rule of thumb is the amount of amps determines the amount of miles per hour charged. An example could be if you have a 20 amp outlet, you’ll get 20 miles of charge each hour your vehicle is charged. Most charging stations are capable of 30 amp connections. Let us help you determine the amperage and location of your charging station. Contact Us today to set up an appointment!

Listed below is an article from PlugInCars.com about car charging stations. It’s a great article they wrote giving basic information and options as it relates to Car Charging Stations.
Cost – Car Charging Stations
The general consensus among experienced EV drivers is that a capable and durable EVSE will cost around $600 to $700. You could spend a little bit less, or twice as much, but that’s the ballpark. This does not include installation. Read on to see which key features—such as portability and connectivity—can send the price higher, or can be avoided to reduce the cost.
By the way, from 2010 through early 2013, many EV drivers could get a free EVSE, courtesy of The EV Project, a program sponsored by the U.S. Department of Energy. But as of March 11, 2013, the program reached its threshold for handing out residential charging equipment, so no more freebies—you’ll need to buy one on your own.
Amperage Capacity – Car Charging Stations
You should buy an EVSE that can handle at least 30 amps. The rule of thumb is that 30-amp service will roughly give you the ability to add 30 miles of range in an hour—just as 15 amps will add about 15 miles in an hour of charging. (These range numbers are somewhat optimistic.)
Keep in mind that most plug-in hybrids (and the Nissan LEAF prior to the 2013 model) don’t take full advantage of the faster rate. That’s okay. It’s still wise to have the capacity to charge at least at the 30-amp level, even if your current car can’t fully utilize the higher amperage, so you don’t have to upgrade in a few years if/when you buy a new EV that has a faster on-board charger. Also, it’s nice to allow friends with faster-charging EVs to get a full charge from your garage.
Note: A 30-amp EVSE will need a circuit breaker rated for at least 40 amps.
Length of Charging Cable, and EVSE Location
Before you buy an EVSE, imagine where your electric car will be parked. Think about the ideal location for this piece of equipment. Now measure the distance between where the EVSE will hang on your wall, and where the charging port is on your car. Cables usually run from approximately 15 to 25 feet. Make sure your cord can easily reach where it needs to go, and think about its length for a potential second plug-in car in your driveway or garage.
Depending on where you locate your EVSE, an electrician might have to run just a few feet of conduit—or dozens of feet. Longer copper runs will add installation cost, but because you’ll charge almost every night, you want it to be as convenient as possible.
Portability – Car Charging Stations
If it’s possible, don’t permanently install your EVSE. In other words, have an electrician install a NEMA 14-50 outlet or something similar (types of outlets used for things like clothes dryers). Then put a matching plug on a pigtail mounted to your EVSE. You can then mount your EVSE right next to the outlet, and simply plug it in. If the time comes when you move, or decide to relocate your EVSE, simply unplug it—and plug it back into another NEMA 14-50 outlet.
This approach costs exactly the same as a hard-wire installation, and makes the device instantly moveable without additional expense. If your EVSE is outside—because maybe you don’t have a garage—then local code might require that you hard-wire the charging equipment. Otherwise, keep your options open.
Connectivity – Car Charging Stations
In this age of smart phones, smart grids, smart this and smart that, you might feel compelled to buy a Wi-Fi-enabled EVSE. That might not be so smart after all. While these fancier products sound cool because they have timers, meters, touch screens and capabilities for monitoring and changing charging events over the web, most long-time EV drivers believe that connectivity adds unnecessary complexity, as well as cost. In some cases, when connectivity is lost, the EVSE can shut down. Besides, many of these remote controllable features are available directly on the car, or from mobile applications. So, the smart money is on dumb but durable EVSEs.
If tracking electricity usage of your EV (for work or tax purposes) is an absolute must, you’ll want to either meter your charging separately, or keep your eye open for add-on devices that perform this function via integration with the smart grid. These solutions are currently being evaluated in pilot projects.
