Charging is becoming easier than ever

It is important to become familiar with the basics of electric vehicle infrastructure to understand what types of charging stations are available for the vehicle model you plan to purchase.

Electricity is more readily available than gasoline and diesel so there are 3 main methods of charging: charging at home, charging at the workplace, and charging at public charging stations. Please read below to understand the difference between charging equipment.

Charging Equipment


Level 1

Level 1 charging uses Alternating Current (AC) power to charge EVs through a 120 volt AC plug. Most, if not all, PEVs will come with a Level 1 cordset, so no additional equipment is required besides the standard wall outlet. The output of the Level 1 charging is connected via an SAE J1772 standard connector (image below). Note that the J1772 connector is standard with most EVs but Tesla Vehicles. Tesla Vehicles come with an adapter, which allows them to use the non-Tesla charging equipment.

  • Approximately 1kW of power

  • Provides about 4 to 5 miles of range per hour

  • Powered from standard wall outlet of 120 volts

Level 2

Level 2 charging uses AC power to charge EVs through 240 or 208 volt AC plug. Most homes have 240 volts whereas 208 is used in most commercial uses. Since Level 2 charging stations can charge a typical PEV overnight, Level 2 is a common charger installed at the home. Over 80% of public EVSE ports in the US were level 2. EVSE Port Database Level 2 charging equipment also uses the J1772 connector, same as Level 1.

  • Approximately 3 to 20 kW of power

  • Provides about 12 to 60 miles of ranger per hour

  • Typical EV plug found in homes, garages, and most public charging stations

Level 3 or DCFC

Level 3 charging, also known as DC Fast Charging (DCFC), is the fastest charging station currently available. Instead of using AC power to charge EVs, a DCFC uses Direct Current (DC) power to directly charge the EV battery. At over 15% of public EVSE ports in the United States, DCFC are usually located along heavily trafficked corridors to enable quick charging when necessary. Images of connectors types below.

  • Approximately 20 kW to 50 kW of power

  • Can charge many EV plug-in vehicles to 80 percent in about 20-30 minutes

  • Typically costs as much as $50,000 which is why they aren’t used for individual residences

Installing stations

  • Home Charging

    Level 2 charging is most commonly found at homes and most businesses. Charging at a rate of 12-80 miles per hour, these units are practical for topping off around town or charging larger batteries overnight at home. The chargers range in price from about $200-$800 and can be as small as a heavy duty extension cord. Level 2 chargers can vary in their power outputs, but require 208-240 volts and are often on a dedicated circuit. While there are ways to share a dryer outlet or other 240 volt outlets using a smart splitter (1,2,3) if the breaker panel has room and isn't too far from where the charger is installed, this is often the best method.

    Installing a dedicated 240V outlet usually will require an electrician (4). The cost to install the outlet can range quite a bit from building to building, will depend on the rates of local electricians, but could take as little as 2 or 3 hours and $100 in materials for a simple install. Typically, an install will require a breaker ($20), an outlet and box/cover ($20), miscellaneous connectors ($20) and appropriately rated wire and conduit ($4-5/foot). Once the outlet is installed, most chargers are simply attached to the wall with a few screws and plug into the outlet like a dryer.

    The power needed to fully charge your EV will range based on its battery size. Battery sizes can range from 20kWh (in some plug in Hybrids) to 170 kWh in the extended range Ford Lighting. A 60kWh battery, for example, would cost about $8 to charge from 0%-100% (based on a national average electricity cost of $0.133/kWh).

  • Public Charging

    Public EV charging locations are continually being added across the country. Businesses, municipalities, along with companies dedicated to expanding their charging infrastructure are making it easier for EV drivers to “fill up”.

    There are a few ways to categorize public charging. You could group stations into free to charge or pay to charge, Level 2 or Level 3 or even independent stations or stations belonging to a larger network of chargers.

    If you’re looking to install a charging station at your business or other public place you’ll probably be looking at a Level 2 system. Some install in the same way your home charger would, while others require bolting the unit to ground and connecting to the cloud. If the intent is to offer free charging with no interface, like a clipper creek station, you can easily install single head chargers to a wall or even two dual stations to a single pedestal giving you the ability to charge 4 vehicles. If you’re looking to charge a fee for users to use the station, you’ll need a networked charger. There are many options here. You can buy the unit outright and pay a service fee to have the station connected to the cloud and able to process payments. Alternatively, some manufacturers offer their units free of charge if they’re able to collect the fees from the charging station. It would be advisable to reach out to a few companies to see what might best fit your needs.

  • Workplace Charging

    With proper workplace charging implementation, employers can help increase the convenience and affordability of driving electric for their employees. Workplace charging can demonstrate a commitment to adopting advanced vehicle technologies and can differentiate the workplace as a more sustainable one. Additionally, for some employees, EV charging can be an added benefit they consider when choosing to work there.

    As with home charging, Level 2 stations are the most common at workplaces, and each Level 2 connector is capable of charging more than one vehicle per day. It is often necessary for organizations to establish policies that encourage employees to share the stations and move their charged vehicles after a certain amount of time. Some Level 2 stations enable easier sharing with multiple connectors that allow vehicles to charge in succession without owners having to disconnect or move vehicles.

    Employers should consider developing a policy that specifies what employees should do when there are more EVs that need to charge than there are charging stations available. There are many resources available to learn more about workplace charging including one from the Department of Energy.

Choosing to install Networked or Non-Networked chargers

Non-networked chargers, also sometimes referred to as “dumb chargers”, are basic chargers similar to those installed residentially. They are simply on or off and don’t have the ability to take payment or limit their usage.

Networked chargers have many more features, can connect to the cloud via WIFI or cellular service, are able to take payment and almost always require an app to activate the unit. Networked chargers are usually more costly upfront and require a monthly/annual subscription or service fee to function.

The added expenses for networked chargers sometimes doesn’t pay off in our region with the low cost of electricity, the speed of the charger and the reduced demand.

Public Level 2 Charging in our region

The majority of Public Level 2 Charging in Montana, Wyoming and Idaho is Free! The rest has an average price range of $0.31-0.37/kWh.

Diesel-powered EV charging

Charging from the grid isn’t always the greenest option. Some propane, natural gas, or renewable diesel-powered electricity generators can actually be cleaner than some electrical grid sources.

On a related note, charging an EV from a petroleum powered generator is almost always more efficient that burning that same fuel in a non-hybrid, internal combustion engine vehicle. By using, for example, diesel in a generator to produce electricity for an EV, you are effectively creating a hybrid vehicle that we all know is more efficient.

Some simple math to right illustrates this.

One notable caveat would be in extreme cold weather when cabin heating or battery conditioning and performance degradation will depletes the energy stored in the EV’s batteries, thereby reducing its effective range. Auxiliary diesel heaters, used in some electric (and diesel) school buses, helps to address this.
