What Kind Of Costs Are Involved In Charging An Electric Vehicle?

Electric Car Buyers Need To Know The Answer To The Question, “Will My Electricity Bill Go Through The Roof If I Charge At Home?” Because You Are Physically Plugging In A Battery The Size Of A Volkswagen Into Your Home, You Would Think That It Would Make The Electric Meter Spin Quickly, Like It Did When Clark Griswold Plugged In A Million Strands Of Christmas Lights, Right?

But Even Though An Electric Vehicle (Ev) May Become One Of The Most Power-Hungry Devices Connected To Your Home, You Shouldn’t Forget That The Money You Spend On Gas Will Probably Go Down By At Least The Same Amount, And Maybe Even More.

The Amount That An Electric Vehicle Will Add To Your Monthly Electric Bill Depends On A Number Of Things. However, There Is No Need To Worry Because The Amount Can Be Easily Calculated And Is Not Likely To Double Or Triple The Average Monthly Electric Cost.

What Is The Price Range For Charging An Electric Vehicle At Home?

You Need To Know The Following Things In Order To Generate A Ballpark Figure For How Much More Your Monthly Electric Bill Would Increase If You Drive An Electric Car:

  • The Total Number Of Miles Driven In A Single Month
  • The Electric Vehicle’s Efficiency, Measured In Kilowatt-Hours Per Mile And Available On The Government Website
  • Cost In Pennies Per Kilowatt-Hour For Power Generated Locally

Even In That Case, The Cost Will Differ Depending On A Number Of Different Factors, But We Can Give You A General Estimate. Unlike The Consumption Of Gasoline, Which Is Measured In Gallons, The Consumption Of Electricity Is Measured In Kilowatt-Hours. If You Have Ever Glanced At The Energy Bill For Your House, You Should Be Familiar With The Unit Of Measurement Known As A Kwh.

To Calculate An Exact Cost Per Kwh, Take The Total Amount That Was Charged For Power On Your Most Recent Bill And Divide It By The Amount Of Electricity That Was Consumed. This Will Take Into Account All Of The Fees And Costs That Are Associated With Bringing Electricity To Your Residence.

According To The Energy Information Administration, The Final Value Should Be Something Along The Lines Of $0.1375, Which Translates To 13.75 Cents Per Kwh. This Is The Most Recent Published National Residential Average From December 2021. You May Wish To Run The Same Calculation For A Few Different Monthly Electric Bills In Order To Achieve An Average That Is More Accurate.

This Will Allow You To Account For Month-To-Month Changes In The Electric Rate As Well As Other Billing Variations Such As Differences In Metering Or Surcharges.

We Are Able To Calculate The Cost Of Charging A Well-Known Electric Vehicle (Ev), Such As The Tesla Model Y Long Range All-Wheel Drive, Using The Price Of Energy That Is Already Known. The Epa Estimates That This Model Will Consume 28 Kwh Over The Course Of 100 Miles, Which Works Out To 0.28 Kwh Per Mile If The Decimal Point Is Moved Two Places To The Right.

From This Point Forward, You Can Calculate Your Total Kwh Consumption By Multiplying The Usage Of 0.28 Kwh Per Mile By The Number Of Miles You Travel In A Month. The Epa Incorporates Vehicle Consumption And Charging Losses Into This Estimate.\

Because There Are Energy Losses Associated With Drawing Power From The Grid And Transferring It To The Battery, You Will End Up Paying More Than The Amount That The Vehicle Itself Is Consuming.

Driving 1,000 Miles Per Month (A Nice Round Number That We Are Using For Easier Visualization), You Would Take 0.28 Kwh X 1,000 Miles To Get An Overall Consumption Of 280 Kwh, Then Multiply That By The Rate Of $0.1375 Per Kwh To Get The Total Cost Of $38.50 For A Model Y Long Range Awd To Drive 1,000 Miles Per Month.

This Is The Cost Of Driving 1,000 Miles Per Month In A Model Y Long Range Awd. Voila!

Several Potential Contributors To An Increase In Your Monthly Electric Bill

According To Statistics Provided By The Energy Information Administration, Adding An Additional $38.50 A Month To The Typical Electric Bill In Order To Charge An Electric Vehicle At Home Would Result In An Increase Of 33 Percent. It Is Impressive That It Costs Less Than $40 To Drive A Distance Of 1,000 Miles, But This Number Could Go Up Or Down Depending On How Much You Drive And Where You Reside, Which Could Either Have More Expensive Or More Reasonable Electricity Rates.

If There Was No Change To Any Of The Other Aspects Of The Equation, The Average Cost Per Kilowatt-Hour In The State Of California In November 2021 Was 23.76 Cents, Which Resulted In An Increase Of The Monthly Cost To $66.53 A Month.

A Less Fuel-Efficient Electric Vehicle Might Potentially Have A Higher Operating Cost. Because It Requires More Energy To Travel The Same Distance, An Electric Vehicle Rated With A Lower Efficiency, Such As The Audi E-Tron Quattro, Which Uses 0.43 Kwh Per Mile (Compared To The Model Y, Which Uses 0.28 Kwh Per Mile), Would Result In An Increase In Cost From $38.50 To $59.13, Based On The National Average.

The Examples That Were Just Given Are The Best-Case Scenarios That Meet The Efficiency Standards Set By The Epa. In Point Of Fact, The Efficiency Of An Electric Vehicle (Ev) Shifts Depending On The Conditions In Which It Is Driven, Just Like The Efficiency Of A Conventional Gasoline-Powered Automobile Does When The Load Of The Vehicle, Changes In Height, And Temperatures All Alter.

The Amount That It Expensed To Recharge Our Tesla Model Y

Our Total Charging Costs Of $183.90 To Travel 2,011 Miles In Our Model Y Long Range Paint A Less Rosy, But More Realistic Picture Of How Much It Costs To Recharge An Electric Vehicle, Including The Cost Of Dc Fast Charging For Long-Distance Drives. In November, We Made The Purchase Of A Model Y Long Range.

In The First Four Months That We Owned The Vehicle, Our Monthly Expenses Averaged $45.98, Which Is Close To The Number That Was Estimated Above; However, This Was Based On 503 Miles Per Month, Which Is Only Half The Number Of Miles That Were Estimated Above. In Reality, Our Expenses Ended Up Being More Than Twice As High As The Estimate.

Why Is There A Distinction? Our 505 Miles Included Some More Expensive Dc Fast Charging, Sometimes Known As Tesla Supercharging, In Addition To The Energy Losses That Occur While Home Charging. We Were Able To Save A Buck Or Two By Taking Advantage Of The Random Free Level 2 Chargers That Were Offered In Retail Outlets. However, These Chargers Often Only Covered The Cost Of The Short Journey.

The Majority Of Our Supercharging Charges ($104.69) Came From A Single Road Trip That Covered Over 700 Miles And Required Four Stops At Superchargers. Home Charging Accounted For Approximately 1,300 Miles Of Our Total Driving Distance Of 2,011 Miles, At A Cost Of $79.21 Per Mile.

Our Long-Term Model Y Has Also Been Mostly Driven In Cold Weather With Frequent Cabin Preconditioning (Plugged And Unplugged); This Shows In Its Efficiency, Which Is An Average Of 31.2 Kwh Per 100 Miles (Or 0.312 Kwh Per Mile). This Requires More Energy To Travel The Same Distance Compared To The Epa Rating Of 28 Kwh Per 100 Miles For The Model Y. (0.28 Kwh Per Mile).

When We Look At How Efficiently We Charge At Home, We Can Also Learn Where Some Of The Costs Have Been Incurred. Optimally, Charging Efficiency Should Be 100 Percent With No Losses To Heat Or Battery Conditioning; However, According To The Teslafi Data Logger That We Use To Record All Charge Sessions, Charging Efficiency Has Ranged From 69 Percent To 96 Percent For Longer Charges.

Charging Efficiency Is The Measure Of The Total Energy Used In The Charging Process Versus The Energy Added To The Battery.

This Means That During Home Charging, We Utilized 672 Kwh Of Energy To Fill The Car’s Battery With 547 Kwh, Or An Extra 127 Kwh Solely To Facilitate Charging, Which At The Average Cost Per Kwh Comes Out To $17.46.

It Should Not Come As A Surprise That Dc Fast Charging Has Been Shown To Be A More Efficient Method Of Charging, With The Five Total Sessions Ranging From 97 Percent To 100 Percent Efficiency. This Is Because Converting Home Ac To Dc Onboard The Vehicle In Order To Charge The Battery Always Represents An Energy Loss. However, Rapid Charging Comes With Its Own Set Of Concerns Around The Cost And Health Of The Battery.

What Does It Cost To Dc Fast-Charge An Electric Vehicle?

The Cost Of Dc Fast Charging Can Be More Than Double Or Even Treble That Of Charging At Home, Which Can Eat Away At Any Possible Savings On Petrol. It Is Important To Keep In Mind That While “Rapid Charging” Is Faster Than Charging At Home, It Does Not In Any Way Compare To The Ease With Which An Internal Combustion Engine Vehicle May Be Refueled At A Gas Station.

Our Position Is That If You Own An Electric Vehicle, You Should Charge It At Home Using A Level 2 Charging Station, And You Should Save Fast Charging For Road Trips Or Emergencies.

When We Have Used Tesla’s 150- Or 250-Kilowatt Superchargers, We Have Been Billed Between 30-37 Cents Per Kwh.

A Kw Is The Unit Of Measurement For Power And Charging Speed Potential. Tesla Supercharger Billing Rates Vary By Location. In Our Experience, Most Of The Time In The State Of Illinois, We Have Used These Chargers. See What We Mean When We Say That Fast Charging Is Not As Fast As Filling Up?

The Most Costly Supercharger Fill-Up For Our Model Y Cost $19.72 (Including Taxes), Yet It Added 69 Percent To Its Battery Capacity (From 26 Percent To 95 Percent) And 235 Miles Of Range In 49 Minutes. Along With The Charger Itself, The Charging Speed Is Dependent On The Surrounding Weather Conditions, The Conditions Of The Vehicle, And The State Of Charge Of The Battery.

Charging Speed Typically Slows Down Once The State Of Charge Reaches 80 Percent; This Meant That We Had To Wait Until It Reached 95 Percent Because We Were Driving And Needed The Maximum Range Possible.

Electrify America Charges Guests 43 Cents Per Kwh And Paid Members 31 Cents Per Kwh In The State Of Illinois. Evgo Charges Between 22 And 29 Cents Per Kwh Depending On The Membership Level Of The Customer. These Billing Rates Can Alter Depending On The Location Of The Customer.

Not All Direct Current Fast Chargers Are Made Equal, As The Speed Of A Charger Can Range Anywhere From 24 Kw To 350 Kw, And Not All Automobiles Are Compatible With The Quickest Charging Speeds Or Even Come Near To Their Stated Potential In Practice (But That’s Another Subject).

The Rate Of 14 Cents Per Kwh At Home For A Maximum Charge Speed Of 19.2 Kw Is Used As A Comparison Here. However, Car Manufacturers Frequently Provide A Limited Number Of Free Kwhs Or Years Of Dc Fast Charging For Their Customers.

You Will Be Charged By The Kwh Whenever It Is Possible At Tesla Superchargers And Other Fast-Charging Networks Such As Electrify America And Evgo; However, Depending On The Legislation In Your State, You May Also Be Charged By The Minute. “We Feel Paying On A Per-Kwh Basis Gives A Fair And Consistent Charging Experience To Ev Drivers,” Electrify America Is Quoted As Saying. We Are Collaborating With The Relevant Authorities To Ensure That We Adhere To The Many Procedures That Are Necessary For Us To Be Able To Offer Charging For Electric Vehicles On A Per-Kwh Basis.

If You Only Charged With Dc Fast Chargers, Even When They Were Provided For Free (Like With Our Model Y), Your Cost Savings Would Be Reduced In Comparison To Charging At Home. Additionally, Frequent Dc Fast Charging Is Not Suggested Because It Can Hasten The Deterioration Of The Battery’s Health.

Using The Combined Efficiency Estimates Provided By The Epa, It Would Cost $84 To Drive A Model Y 1,000 Miles Using Only Supercharging At A Cost Of $0.30 Per Kwh, As Opposed To The Cost Of $39.54 To Do So At Home.

Cost Comparison between Electricity and Gasoline

Do Not Confuse This Fact With The Fact That Electric Cars Are Immediately Cheaper To Own Because, At The Moment, The Additional Expense Related To Purchasing An Electric Vehicle And Installing Home-Charging Equipment Does Not Make A Quick Payoff A Sure Bet. However, If You Charge Your Electric Vehicle At Home, It Is More Affordable To Refuel Electric Vehicles Than Comparable Gasoline Cars.

When Compared To Your Current Electrical Bill, Charging An Electric Vehicle (Ev) May Result In A Significant Rise; But, In Most Circumstances, The Cost Of Charging An Ev Is Significantly Less Expensive Than The Cost Of Filling A Gasoline-Powered Vehicle.

The Department Of Energy Estimates That The Average Cost Of Operating An Electric Vehicle (Ev) Is Roughly Equivalent To That Of Operating A Comparable Gas Vehicle.

Note From The Editor: This Article Was Revised On March 11, 2022 To Make It Clear That The Consumption Estimates Provided By The Epa Take Into Account Billing Losses.

How much money does it really set you back to charge an electric vehicle?

Although The Cost Of Electricity Might Fluctuate From Month To Month In California, The Typical Rate Is Approximately 18 Cents Per Kilowatt Hour (Kwh). At This Pricing, It Would Cost Approximately $7 To Fully Charge An Electric Vehicle Such As The Nissan Leaf, Which Has A Battery Capacity Of 40 Kwh And A Driving Range Of Approximately 150 Miles.

What Are The Fees Associated With Charging An Electric Vehicle At Walmart?

The price per session is $1, with additional charges ranging from 25 cents to 99 cents, depending on the power level of the vehicle.
