Everything You Need to Know About Home Electric Vehicle Charging Stations

Installing an electric vehicle charging station at home may be easier than you think, but there are a few things you should consider first. Here's everything you need to know about installing an electric vehicle charging station at home .

If you're thinking about buying an electric car or have just bought one, you may have a lot of questions about how to charge it. Don't worry. We have the answers.

Do you need a dedicated electric vehicle charging socket at home?

You may be wondering whether you need a dedicated electric vehicle charging outlet in your home. While the answer is technically 'no,' you may want to install a dedicated Level 2 charger if you use an electric vehicle as your primary means of transportation.

Unlike electric vehicles such as plug-in hybrids, which use small batteries to supplement their internal combustion engines, pure electric vehicles only use very high-capacity batteries. Therefore, electric vehicle batteries require a significant amount of electricity to charge.

Most electric vehicles come with an adapter that plugs into a standard 110-volt wall outlet. These Level 1 chargers look like oversized extension cords and are handy if you ever find yourself in a situation where you don't have a high-capacity charger available.

The downside to that convenience is that a standard wall outlet only adds 3 to 5 miles of range per hour. At that rate, a 10-hour overnight charge would only provide about 50 miles of driving range.

The flexibility of fast charging ensures you always have enough range for unplanned errands or last-minute trips, and this is where a level 2 fast charger comes in handy.

Unlike a standard charger, a Level 2 setup is about five times faster, increasing charging speeds to about 25 miles per hour. Overnight charging typically provides enough time to fully charge most EVs.

Standard North American Level 2 chargers use the universal J1772 connector; you can rest assured that your EV uses the J1772 setup.

Important Note: Remember that regularly charging your EV to 100 percent and draining it to near zero will shorten the life of the battery. For this reason, you can adjust your charger and vehicle settings to limit the charge to 80 percent (which is actually often the default setting) to improve battery life.

Is it necessary to set up a level 2 charger at home?

You'll have a few options when purchasing a Level 2 charger, including amps and cable length. While most Level 2 chargers operate at between 16 and 30 amps, some use higher wattage settings of 50 amps or even 80 amps.

A 50-amp or 80-amp charger may seem appealing because it delivers more electrical power for faster charging (providing a range of 37 to 65 miles per hour), but you'll want to make sure your car is equipped with a higher-capacity, higher-amp compatible onboard charger.

Don't worry about overloading your car's electrical system, as the higher-amp charger will automatically adjust based on what your car can handle. But if your car is compatible with that higher amp, you'll find the increased charging speed a worthwhile upgrade.

As for charging cable length, you should use the longest cord available as home parking can often involve unforeseen obstacles like cluttering up the garage or maneuvering around other cars.

Installing a wall charger can cost anywhere from $300 to $1,200, and you'll want to consult a professional before installing it. If you don't already have the wiring for a 240-volt connection, budget $250 to $2,000 for professional installation.

Also, note that 50-amp devices may require upgrading your electrical box. If you live in an apartment or townhouse that doesn't come pre-wired for a car charger, the cost of installation can be significantly more expensive.
