How Much Energy For An EV Station?


How Much Power Is Required For

The Breakdown Of EV
Charging Setup Use


An electric vehicle charging setup in Easton, PA uses your home electricity to power your vehicle. Because of this, it is useful to know how much power your charger uses.

Shafnisky Electric has over 35 years of experience as an electrician and extensive professional experience with electric vehicles. Over this time, we’ve learned about how much power you need for your charging setup.


Measurements Of An
EV Charging Station

There are a few important units to consider when calculating how much power your EV charging setup uses. The average electric car uses 7,200 watts (W) of electricity, is around 35 amps, and performs best with a 240-volt outlet.

EVs use an average of 0.35 kilowatt-hours (kWh) per mile. But to better understand this, it’s best to break it down into units.

Volt – Electrical Current

Volt is a unit many homeowners are used to, considering your outlets are measured in voltage. The standard for homes is 120v and 240v, but fast charging stations for cars use 480v, which is uncommon in residential areas. The unit is of electric potential or rather how much pressure there is in a circuit. The higher the voltage, the stronger the current.

Watt – Vehicle Power

Watt is what horsepower is measured in, and the general unit is what we use to measure any type of vehicle’s power source. One horsepower equals 745.7 watts. Basically, a wattage measures how powerful the energy is as well as the overall amount of energy.

Amp – Amount Of Energy

Amps measure the amount of energy in diameter, hence why the cables for EVs are so wide and those for phone chargers are so thin. Amps are a way to measure the voltage of something, such as an EV charging station. Amperes directly measure electricity, while volts represent the potential of a source.

KWh – Energy Per Hour

The unit of kWh simply stands for kilowatts an hour. This is how we measure how much power/energy your electric vehicle and charging station use. Think of it as miles per gallon on a standard car. We use this to find out how much you pay for the fuel source as well as how much fossil fuel, or in this case electricity, the car and station use.


The Math For Your EV
Charging Setup

While the amount of energy you use is important, so is the cost of that energy. Finding out how much you pay for your EV charging station takes a simple math equation.

  1. Find Your Vehicle’s kWh/100 miles – this is listed in your car manual (for example, the Tesla 2023 Model Y uses around 28 kWh per 100 miles).
  2. Find the electricity rate – this is around 16 cents per kWh at home or around 45 cents per kWh for public stations.
  3. Multiply – using the formula with the Tesla 2023 Model Y, that’s $4.48 per 100 miles at home or $12.60 per 100 miles for a public station.

In Northampton County Area

An at-home EV charger uses around 12 kWh per day. To put things into perspective, this is the same as an active furnace or water heater. So, if you use those appliances, an EV is no different. In the long run, an EV charger uses less per year than a refrigerator or another appliance that runs nonstop.


At Home EV Charging Setup Vs. Public

While the energy use is around the same if the chargers are both level 2, you pay a lot less for a charging setup at home. You’ll pay at least twice as much for a public charge but likely closer to three or four times as much.
