Level 2 EV Charging
While level 1 is the most cost-effective EV charging solution, upgrading to level 2 EV charging brings added convenience. Charging times vary between vehicles, but typically owners are saving hours in charging times each day. If you are sharing an electric car between multiple drivers, have a longer than average commute, or cannot charge your EV at work, upgrading to a level 2 charging unit brings increased peace of mind.
Installing a level 2 electric vehicle charging station at home should be done by a professional licensed electrician. While the installation is meant to be permanent, it can be removed from the property and installed elsewhere if you decide to move. Alternatively, having an upgraded EVSE installed is a unique feature to advertise when selling your home. The price of level 2 home charging units and installation are both very reasonable.
Why Upgrade to a Level 2 Charger?
Upgrading to level 2 charging allows you to quickly charge your electric car while you sleep, work, enjoy a meal, or spend time with family and friends. A level 2 charger supplies AC power safely to your electric vehicle or plug-in hybrid to keep your batteries replenished and waiting to go.
- The quicker charging systems allow you to fill the limit of your battery 3-5 times faster.
- Safe, reliable, and efficient charging.
- Save money by using off-peak prices when charging your vehicle.
level 1 – 120v 1.4kw – 7.2km of range per hour
level 2 – 240v 3.8kw – 19km of range per hour
Options for Level 2 EV Charging
Charging at level 2 refers to the voltage used by the electric vehicle charging system (240 volts). Level 2 chargers come in a variety of amperages, ranging from 16 to 40 amps. The two most common Level 2 chargers are 16 and 30 amps, also referred to as 3.3 kW and 7.2 kW, respectively. This configuration matches the onboard charger (obc) components.
Level 2 chargers are often purchased separately from the vehicle, although they are frequently bought together with the car. This charger requires a bit more complicated setup, as it plugs into a standard 240-volt outlet. All of these chargers possess an SAE J1772 connector and are available online in Canada and the United States.
If you have a plug-in hybrid with a limited electric range or won’t be driving far between charges, you probably don’t need a fast charger. Quick charging may only be necessary for long distances when the available speeds are higher than those of public charging terminals. Most plug-in hybrids have a limited electric range, meaning they can be completely charged in less than 5 hours using the incorporated Level 1 (120 V) charger. Most owners of these vehicles may not need a Level 2 charging station.
Cost of Level 2 Car Chargers
Most Chargers themselves will cost between $400 to $600. The cost of setting up a level 2 charger is incredibly variable.
- The capacity of your electrical panel.
- Your home’s age.
- Location of the charging station.
- Area of your electrical panel.
- Accessibility for running wires
- Is your basement ceiling open or drywalled?
It Will all affect the final cost of putting an electric vehicle charger in your home. Permits are required for the installation process. As an electrical contractor, we handle communication with ESA. Make sure your electrician is professional and has experience in Level 2 Charging.
Circuit Sizes for Level 2 Charging Stations
The last point to consider when choosing a charging station size is the capacity of the electrical circuit. If you attempt to charge a car at a rate equal to or higher than your wiring capacity, you will flip the circuit breaker. You should restrict the charging rate to 80 percent of circuit capability unless the circuit is rated for continuous use. This is a reason for charging at slower speeds, as efficiency is also a factor.
Line losses increase, the longer the wiring between your main panel and your charging station. These losses are usually less than 2 percent of the electricity used. With adequately sized wiring, these losses are generally less than 2 percent of the energy usage. 2 percent can add up, given the high electricity consumption of EVs. The average EV that runs 30 miles per day is 3600 kilowatt-hours per kilometer. That’s 73 kilowatts or two to four days worth of electricity use.
Most charging stations can set limiting charging speeds to the maximum allowable capacity. Many plug-in vehicles also can limit their charging rates and charging times. This feature can be used to keep actual charging rates within the circuit’s capacity and to reduce charging rates further to minimize line losses. Additionally, charging at off-peak hours will save more money.
