Plug-in electric vehicles

Also called PEVs, plug-in electric vehicles have a rechargeable battery instead of a fuel tank and an electric motor instead of an internal combustion engine. A PEV runs entirely on battery power, using an electric motor to propel itself. Drivers recharge the battery at a plugin or charging station instead of filling up at the gas pump. Example: Nissan Leaf.

Plug-in hybrid electric vehicles

Known as PHEVs, plug-in hybrid electric vehicles have both a battery and a fuel tank and an electric motor and an internal combustion engine. The combination of a battery (which is predominantly recharged by electricity from a plug-in) and a gasoline-powered internal combustion engine extends the range of the vehicle. Example: Chevy Volt.

• A parallel hybrid uses both a combustion engine and an electric motor to deliver power to the vehicle’s wheels. The vehicle can be powered by just the electric motor, just the combustion engine, or a combination of both, depending on driving conditions. Example: Toyota Prius Plug-in, Ford Fusion Energi.
• A series hybrid is directly powered only by the electric motor. The combustion engine is used only to recharge the battery, acting as an electric generator that converts gasoline to electricity. This type of vehicle often is called an extended-range electric vehicle. Example: Chevrolet Volt.

Plug-in hybrids can be further categorized by the way they manage gasoline and electricity.

Hybrid electric vehicles

Also known as HEVs, hybrid electric vehicles are a type of hybrid vehicle that combines the internal combustion engine with a hybrid drive train. These vehicles improve the fuel efficiency of the internal combustion engine by powering some of the propulsion with electricity and running solely on battery power while the car “idles.” Hybrid electric vehicle batteries do not recharge by plugging in. Example: Toyota Prius.

The U.S. Environmental Protection Agency has more about electric and plug-in hybrid electric vehicles in its Green Vehicle Guide. You can also find more information here.

• Level 1: All plug-in vehicles come equipped with a Level 1 charging cord that can travel with the vehicle. Simply plug into a standard 120-volt electric outlet. Eight hours of charging will provide about 40 miles of range for most vehicles.
• Level 2: This requires a 240-volt connection or outlet, the same voltage a clothes dryer or water heater uses. Most EVs will get between 20 and 30 miles of range per hour of charging depending on the vehicle and charger. Level 2 chargers are commonly installed in homes and businesses and are used for the majority of EV charging.
• DC fast charger: This type of charger is typically found at public stations. They are compatible with most EVs and provide a rapid and convenient charge, typically providing a charge of up to 100 miles in less than 30 minutes.

Public Charging Stations

Expanding access to public charging infrastructure is a critical part of Minnesota Power’s efforts to support EV drivers in northern Minnesota. Minnesota Power is planning to install 16 DC fast chargers in strategic locations throughout the region* and is partnering with local businesses to provide public Level 2 charging stations.

On the homefront

Every home has the potential to be an EV fueling station, but there’s no two ways about it—charging an EV takes longer than the 10 minutes it takes to fill up at your average gas pump. Still, it’s hard to beat the convenience of plugging in at home before you go to bed and having the car ready to roll in the morning. Generally speaking, you’ll need a 120- or a 240-volt outlet and appropriate charging equipment, also known as EVSE, or electric vehicle service equipment, to charge your EV’s battery. Charging times vary by EV model and the type of charger used.

• Level 1*: All plug-in vehicles come equipped with a Level 1 charging cord that can travel with the vehicle. Simply plug into a standard 120-volt electricity outlet. Eight hours of charging will provide about 40 miles of range.
• Level 2*: This takes a 240-volt outlet, the same voltage an electric clothes dryer or water heater requires. You’ll get between 20 and 30 miles of range per hour of charging. Because most EV charging is done at home, EV experts recommend you install a Level 2 charger. The charging unit is about the size of a dinner plate with a long cord and costs between $300 and $3,000, depending on the brand and style of unit you purchase.

  The complexity and cost of installing your Level 2 charger will vary depending on your personal circumstances. Some things to think about when deciding on a Level 2 charging unit:

  • Hard-wired or plug-in? If you want the unit hard-wired, we recommend working with a licensed electrician. If you go the plug-in route, simply plug the charging unit into your 240-volt outlet.
  • Do you have 240-volt service near your garage or where you typically park the vehicle? If you don’t, we recommend that you hire a licensed electrician to install a circuit with the appropriately sized wire and breaker for your unit. Amperage depends on the charging unit you purchase. If you have access to 240-volt service, you’ll need to identify a location for mounting the unit and decide which wiring style you’d like.

  Level 2 chargers also are available at many public charging stations.

• DC fast charger*: These chargers are typically available at public stations —— you won't find them at most homes. They are compatible with most EVs and very fast, typically providing a charge of up to 100 miles in less than 30 minutes.

* Charging speeds are determined by volts and amps supplied, but other factors to consider are the top charging speed an EV will accept. Speeds are also impacted by the State of Charge (SoC) (batteries that are closer to “full” tend to curve the charge at a slower rate), as well as outside ambient temperature.

Out and about

The network of public charging stations continues to expand as more EVs hit the road. The increasing number of public options is helping to soothe any “range anxiety” EV drivers might have about running out of juice with no charging stations nearby.

Various online tools and mobile apps for locating charging stations are available. One of the most popular is PlugShare, a comprehensive and up-to-date database of EV charging stations in North America, Europe and Asia. Below is a map showing available charging stations within our service territory.
