Electric Vehicle Chargers

Chargers by Type

There are three major categories of chargers, based on the amount of power the charger can provide.


Common Questions


Where can I purchase a home charger?

We encourage you to locate and buy Eligible Chargers from available outlets.

What Level 2 charger amperage do I need?

Level 2 chargers come in a variety of amperages, from 30-80 amps. Charging speed isn’t entirely dependent on the amperage of the charger. Electric vehicle batteries have maximum charging amperage limits. Many older BEVs and PHEVs can only accept a maximum of 32 amps while charging on a Level 2 charger. While plugging into a higher-amperage charger won’t harm your vehicle, it simply won’t charge any faster. When you make the decision to buy a L2 charger, make sure you aren't buying more amps than you need! Look in your vehicle’s manual to determine its maximum charging amperage. 


You can also save money by buying an ENERGY STAR certified Level 2 charger. The average home charger sits in “standby” mode 85% of the time. An ENERGY STAR certified charger uses 40% less energy in standby mode. 


Some chargers have Wi-Fi capability, which can pair with a smartphone app to conveniently program and remotely control your charging, allowing you to take advantage of off-peak cost savings and participate in managed charging programs. 

Do I need a Level 2 (240 V) charger?

All electric vehicles can be connected to a 120 V outlet, using the Level 1 charging cable that comes standard with many vehicles. While Level 1 charging is slow, it can be done overnight and meets many drivers' charging needs. If you drive less than 40 miles per day, or drive a PHEV, you may be able to save money by charging overnight using a Level 1 charging cable.

Level 2 chargers use higher voltage and amperage, thereby supplying power faster. Level 2 chargers typically charge an EV four to five times faster than a Level 1 cable, but they generally cost between $500 and $1,000 and require wiring to a 240 V circuit. 

Most vehicles don’t need to be fully charged each night. In fact, while a full charge is needed for long trips, it's best for the life of your EV's battery to keep your charge level between 20%-80%.

Can my home or business's electrical panel support a Level 2 charger?

Your home or business might require an electrical service panel upgrade to support a Level 2 charger. Most homes built before the ‘80s have electrical panels of 100 amps (or less). Many new homes have 300-amp or 400-amp service, using two panels. Generally, a 200-amp panel is required to support a Level 2 EV charger. How do you know the amperage of your electrical service panel? Open your panel and look inside of the door. There should be a label that indicates the total amperage the panel supports. 


An electrician will include an “amperage cushion” when calculating your panel’s capacity (generally 125% of the charger amperage) to comply with building codes. Even if you have a 200-amp panel, you still might need a panel upgrade:

  • 30-amp charger: Requires a 40-amp circuit
  • 40-amp charger: Requires 50-amp circuit
  • 50-amp charger: Requires a 70-amp circuit

Finally, even if your panel can support the amperage requirements of a Level 2 home charger, you must also have sufficient circuit breaker space. While breakers can be “piggy-backed”, with a tandem breaker installed in the space of one circuit breaker, the general rule of thumb is that there should be two available circuit breakers for a Level 2 EV charger.

When should I charge my electric vehicle?

Most Level 2 chargers use about 7.2 kW of electricity. For comparison, the average electric water heater uses 4.5 kW, and a typical electric furnace uses around 100 kW. The average EV driver in the U.S. uses 408 kWh to charge their car at home each month (assuming 38.4 average daily miles). EV charging will increase the size of your electric bill, but you can minimize that increase by charging at the right time. Community Energy has time-of-use (TOU) electric rate plans that offer a significantly lower off-peak rate at night, generally after 7:00 pm. So charging overnight can save money. And don’t forget that while your electric bill may go up, you’re still saving money since you’re no longer paying for gas.


Another good reason to charge overnight is to avoid adding stress to the electrical grid. While vehicle electrification is good for the environment, charging at peak times can strain the grid. Avoid charging in the afternoon and early evening, when electric demand is at its peak.

When should I use DC Fast Chargers?

Public DC fast chargers (DCFCs) are great for long-distance trips. In the time it takes to grab a bite to eat or check out a local attraction, you can top off your vehicle’s charge and be ready to get back on the road. Charging at public DCFCs is typically more expensive than charging at home, and it’s better for your EV’s battery to avoid using DCFCs exclusively. But occasional DCFC use can be convenient and easy, and more and more of these chargers are being built across the nation’s travel corridors. Smartphone apps such as PlugShare and Chargeway can show you where to find DCFCs that suit your vehicle and have reviews, photos, lists of local amenities, and trip-planning features.

Important Considerations



EV charging ports/compatible plugs differ by EV manufacturer. The primary types are J1772, CCS, NACS (Tesla) and CHAdeMO. While plug adapters can be purchased, you should refer to your vehicle owner's manual before purchasing a charger.

Some chargers are Wi-Fi enabled, most of these come with a down-loadable phone app that allows you to conveniently program and remotely control your charging - to take advantage of off-peak cost savings. All Level Two Chargers eligible for our Rebate are WiFi enabled.


Level Two (240v) chargers must be professionally installed. The age of your home, your electrical panel capacity (and where it is located), can affect the final cost of putting an electric vehicle charger in your home. The cost of parts and labor can vary widely, typically ranging from $1,200 to $2,500. It’s best to get a few quotes from certified electricians. Some states also require homeowners to get a permit, which can add to the cost.
