A Complete Guide to Level 2 Charging Stations

A Level 2 charging station, also known as Level 2 EVSE (Electric Vehicle Supply Equipment), refers to equipment that can charge an electric vehicle’s battery much faster than a regular 120V outlet. Level 2 stations operate on 208-240V power and typically deliver 10-20 miles of range per hour of charging.

Compared to Level 1 charging, which operates on 120V household power and only provides 2-5 miles of range per hour, Level 2 charging is 3-6 times faster. However, Level 2 is still considerably slower than Level 3 DC fast charging stations that can add 60-200 miles of range in 15-30 minutes.

The maximum power for Level 2 charging is 19.2kW, though most home Level 2 charging stations operate at 3.3-7.2kW. This allows an EV battery to be fully recharged overnight in most cases. The most common Level 2 connectors are SAE J1772 and Tesla. J1772 is considered the North American standard for Level 1 and Level 2 AC charging.

Level 2 stations provide a nice middle ground between the slow trickle charge of Level 1 and the blazing fast speeds of DC fast charging. For many EV owners who charge primarily at home, Level 2 delivers sufficient overnight charging speed. Level 2 stations are also widely deployed in public locations like parking garages, shopping centers, and workplaces.

Benefits of Level 2 Charging Stations

Level 2 charging stations offer faster charging speeds than Level 1 charging, while still being more affordable and widely available compared to Level 3 fast charging stations. This makes Level 2 a good middle ground option for many EV owners.

Some key benefits of Level 2 charging stations include:

  • Faster Charging Than Level 1: Level 2 stations can charge EVs around 2 to 5 times faster than Level 1, with charging speeds of around 10-20 miles of range per hour. This allows EV drivers to charge in a few hours, rather than potentially over half a day with Level 1.
  • More Affordable Than Level 3: Installing a Level 2 station at home costs around $500-$800 on average, significantly cheaper than the $15,000-$50,000 for commercial DC fast charging stations. The charging units themselves also cost less than Level 3.
  • Wide Availability: Level 2 stations are commonly found in public places like shopping centers, parking garages, airports and workplaces. Many EV drivers also install Level 2 charging at home for overnight charging. This wide availability makes finding a Level 2 station convenient.

So for drivers that need faster charging than Level 1 can provide, but don’t necessarily need ultra-fast Level 3 speeds, Level 2 offers a nice middle ground both for public and home charging. The faster speeds compared to Level 1 plus the affordability and availability of Level 2 stations make them a popular choice for many EV owners.

Drawbacks of Level 2 Charging Stations

Level 2 charging stations have some drawbacks compared to faster Level 3 charging stations. The main drawback is that Level 2 charging is slower. While Level 3 charging can add hundreds of miles of range per hour, Level 2 will only add around 10-20 miles of range per hour. This means fully recharging an electric vehicle with a Level 2 station can take many hours.

Another drawback is that Level 2 charging stations require some installation and possibly electrical upgrades. Most homes will need a 240-volt outlet installed to support a Level 2 charger, which adds to the upfront cost. Businesses and public charging networks also require permits, construction, and electrical work to install Level 2 chargers. Overall, Level 2 charging stations are less convenient compared to Level 3 fast charging, but provide a balance of speed and affordability.

The charging unit itself ranges from $400 to $1000 depending on the brand and features. Higher-end networked stations with wifi connectivity, mobile apps, and intelligent charging capabilities cost more. The charging cable is around $300-500.

Other hardware like the mounting stand, connectors, and cable management add another $100-300. Additional costs come from electrical components like the circuit breaker, wiring, and conduit for a hardwired station.

Installation Costs

A basic Level 2 installation with an existing 240V outlet nearby can cost $500-1000 for parts and labor. Running new wiring and conduit from the electrical panel raises costs to $1200-2500. Commercial installations are more complex and can cost $3000-$8000.

Operating Costs

Electricity costs for Level 2 charging varies by location, utility rates, and amount of usage. Charging a 60 kWh EV battery to full would use around 18 kWh and cost $2-4 depending on electricity rates. With Level 2’s faster speed, more sessions can lead to higher costs.

Maintenance is minimal but stations may need occasional software updates or replacement parts after years of use. Network fees also apply for stations with cellular/wifi connectivity.

Installation of Level 2 Charging Stations

Installing a Level 2 charging station at home requires some electrical work and permitting. Here’s what you need to know:

Electrical Requirements

Most Level 2 chargers require a 240-volt electrical circuit, which provides more power than the 120-volt circuits used for standard wall outlets. Installing a 240-volt circuit requires running new wiring from your electrical panel to the location of the charging station. The amperage of the circuit will depend on the maximum amperage draw of the EV charger, usually between 30 to 50 amps.


Most local jurisdictions require an electrical permit to install a 240-volt circuit for an EV charger. The homeowner will need to apply for the permit by providing details about the electrical work being done. An inspector will visit to ensure the circuit is properly installed before giving final approval.

Hiring an Electrician

Unless you have professional electrical training, hiring a licensed electrician is highly recommended for installing a Level 2 charging station. They will ensure proper wiring gauges are used, electrical codes are followed, and the installation is done safely. Make sure to get quotes from multiple electricians before selecting one.

The total cost of purchasing the charger, hiring an electrician, and getting a permit can range from $600-$1200 for a basic Level 2 installation. More complex installs with long wiring runs or multiple chargers can be more expensive. But the convenience of home charging is usually worth the investment for regular EV drivers.

Public Level 2 Charging Stations

Public Level 2 charging stations provide EV drivers with conveniently located places to charge while out and about. These stations are typically found at locations where drivers tend to park for moderate lengths of time, such as shopping centers, downtown areas, hotels, restaurants, museums, etc.

The major charging networks that operate public Level 2 stations in the U.S. include ChargePoint, EVgo, SemaConnect, Greenlots, and Electrify America. Each network has their own mobile app that EV drivers can use to locate stations, start a charging session, and make payments. Payment is commonly done through the app, RFID card, or credit card.

When using a public Level 2 station, proper etiquette is important. EV drivers should move their vehicle once fully charged to open the spot for others. It’s also courteous not to unplug someone else’s vehicle. If all stalls are occupied, wait for a spot to open rather than unplugging a vehicle before it’s finished charging. Being considerate and following posted time limits allows everyone access to these shared public charging resources.

Home Level 2 Charging Stations

Installing a Level 2 charger in your home garage is convenient for daily charging and takes advantage of lower off-peak electricity rates overnight. However, there are some important factors to consider first.

Garage Installation

The garage is the ideal location for home Level 2 charging as it protects the EV and charger from weather while charging overnight. The charger can be wall mounted or installed on a stand. Ample space is needed to maneuver the EV into position and access the charging port.

Electrical Capacity

A dedicated 40-amp to 60-amp circuit is required to deliver the power needed for Level 2 charging. An electrician must assess the home’s electrical panel and wiring to handle the increased load. Upgrades to the electrical service may be needed to support charging two EVs.

Charging Habits

Home Level 2 charging adds roughly 25 miles of range per hour of charging. So overnight charging can easily replenish a day’s worth of driving. However, charging habits must align with the capacity of the electrical system. Simultaneously running other high-wattage appliances while charging could overload the circuit. Staggering charge times is recommended for multiple EVs.
