Frequently Asked Questions

  • Where can I charge when I’m away from home

    If a charge is ever needed while away from home, there are a growing number of online maps and phone apps that can help you find the charging station nearest you – more stations are being installed every day. A simple web search for “public EV charging map” can help you find specific locations. Additionally, many EVs have built-in-apps to help you locate the closest charging station via you vehicle’s GPS map.

  • What EV is best for me?

    With more than 30 all-electric and plug-in hybrid electric vehicles (EVs) on the market, there is an EV for everyone.

    Our electric vehicle guide will help you get started on your hunt.  Be sure to also check with your local dealer's website for details on specific models that meet your driving needs.

    No matter what type you choose, driving an EV will make a difference in your wallet and the environment.

  • How do I charge at home?

    Ask your auto dealer what the vehicle manufacturer recommends for getting your home plug-in ready. Charging times vary depending on how far you drive between charges, the speed of your charging equipment and the capabilities of your EV.

    For vehicles and charging units capable of shorter charging times, higher-power electrical connections may be required - similar to the electrical connection for a household air conditioner or dryer.

  • What EV rates does SDG&E offer?

    EV Rates Can Help You Save

    If you own an EV you can benefit by signing up for an electric vehicle time-of-use rate and programming your car to charge during the cheapest times of night – like midnight to 6 a.m.  Plug in your car at any time and the built-in technology will go to work for you, saving you money.

    Sign up for an EV Rate

    To get the biggest benefit from your EV Rate, charge when rates are lowest - Super Off-Peak (midnight to 5 a.m.).

    How do I choose an EV rate?

    Visit My Account and use our rate calculator to determine the rate with the best savings.  

    We offer two EV Rates:

    1. EV-TOU-2 - A rate for your house & EV

      The EV-TOU-2 rate uses your existing household smart meter to track both your home and EV electricity usage. 

      Managing your home energy use is easy on EV Rates: program your car to charge at night, do your laundry or run your dishwasher in the morning or at night, change your pool pump to run at night. 

      Have solar?  If you have solar and owe money at the end of your year, this rate will help you reduce that cost.  If you don’t owe at the end of the year, you are likely great with the rate you are on.

    2. EV-TOU - A rate for just your EV

      The EV-TOU rate requires a separate meter for your EV.  This meter tracks your EV’s electricity use separately, while your house remains on a tiered rate. A licensed electrician of your choice is required to install this second meter at your expense, which is why most customers prefer EV-TOU-2 that has one meter for both your house and car. 

  • What are the driving ranges?

    According to the U.S. Department of Energy, most electric vehicles can go at least 100 miles on a single charge, compared to 300 for a gas vehicle. 

    When considering plug-in EVs, consider how far you drive each day. In most cases, an overnight charge at home is more than enough to recharge an EV after your typical day’s drive. In fact, most San Diegans drive 30 miles or less each day, requiring only about 8 kilowatt hours of electricity. This is the amount of electricity a standard wall outlet can provide in about 5 to 6 hours.

    Special home charging units can provide this same charge in a little over an hour. It’s important to remember that much like conventional gasoline powered cars, driving ranges will vary depending on how much electricity your car holds and your driving habits. Manufacturer websites have EV mileage information.

  • Is it easy to charge an EV?

    Yes. Knowing your driving needs will help you choose charging options that work best for you. Options include the standard 120-volt charging cord that comes with your car and plugs in to any standard household outlet, or specialized 240-volt charging units installed by your electrician. Your EV dealer and manufacturer can provide you with more charging option information. They can also recommend charging equipment installers in your area. Some EVs and specialized charging units can be programmed to start and stop charging automatically at the times when electricity prices are lower.

  • Where are public charging stations?

    Public charging stations can be found at the U.S. Department of Energy or on Plugshare.

  • How can I charge if I live in an apartment?

    If you live in a multi-unit residence, installing plug-in vehicle charging equipment may require approval from your homeowners association (HOA). Since multi-unit residence installations are often in common areas, it’s important to involve your HOA as soon as possible.
