Want to charge your electric vehicle at home? 10 things to know about home EV charging installation.
Updated: May 1, 2019
According to the Department of Energy, electric vehicle owners nationwide do more than 80% of their charging at home. That’s for good reason: affordable residential electricity rates, convenience, and hands-off overnight charging provide an attractive lifestyle for electric owners.
Providing energy to your car at home is a relatively new concept. To make the most out of home-charging your EV, here are ten tips.
1. Virtually every electric vehicle bought today comes with a Level 1 portable charger that can be plugged into a 120-volt outlet (this is standard in North America). If you buy a Tesla then your vehicle will come with both 120 and 240 volt plugs (Level 1 and 2). L1 is what we use to charge iPhones and razors and laptops--using it for a car can feel slow for most owners (L1 adds about 4 miles each hour, taking days to fully charge an EV battery).
2. EVSE stands for electrical vehicle supply equipment, though the more general term that’s often used is “charging station.” Many EV owners choose to install at home because L1 isn’t fast enough and stations are either hard to find or contain long lines (especially in the San Francisco Bay Area).
3. The SAE J1772 is the standard plug for all electric vehicles on the market, except Teslas--though they come with an adapter that allows Tesla owners to also use the J1772.
4. Make sure to store your charging cord in a safe place, whether L1 or 2. Leaving the cord out continuously can lead to unwanted wear and tear.
5. Portable Level 2 chargers add about 15 miles to your range each hour you charge. The obvious pro here is the ability to take it on-the-go--though that advantage is usually negated, considering portable chargers require a clothes-dryer sized outlet, which are difficult to find just anywhere. These chargers provide from 10-20 amps of power and can cost anywhere from $200-400.
6. Wall-mounted L2 stations typically require a permit, installation, and can be hardwired or plugged-in. These stations typically range from 20-80-amps and on average add about 30 miles each hour you charge your EV. So, charging your electric vehicle overnight with an installed L2 power source will max the mileage out on most EVs.
7. Consider consulting an electrician before installing. Even if you own your home, a little professional expertise can go a long way. For example--you may not have enough spare capacity for the circuit you want to install--which could easily be answered by an electrician. Choosing where to install the station is also an important decision that could benefit from an expert opinion, as well as ensuring that you don’t cause structural damage to your home or yourself.
8. Some states offer incentives and rebates for EVSE installations. Before installing, check to see if your state offers any incentives here. Simply purchasing an electric vehicle will offer state and federal subsidies, as well. As of January 1, 2019, the federal rebate for new EV owners is $3750 (previously $7500).
9. Are you a renter? You likely won’t be able to install a Level 2 charging station at home. If you live in an apartment or condominium but want to install in your garage or designated parking space, make sure to consult your landlord before doing so.
