Does charging an electric car at home raise your electric bill
How Much Does Your Electric Bill Go Up With A Tesla?
As of February 2023, the average residential electricity rate in the U.S. is about 23 cents per kilowatt-hour (kWh).
Switching to an EV means charging your car at home, naturally increasing household electricity usage. Understanding this cost is crucial for financial planning and compares favorably to the ongoing costs of gasoline.
A Teslas battery capacity and your driving habits are key factors that dictate the increase in your electricity expenses.
The cost of charging an electric car can be estimated by examining the size of its battery and the cost per kilowatt-hour (kWh) of electricity in your area.
For instance, the Tesla Model Xs 100 kWh battery will cost a certain amount to charge from empty to full based on local electricity rates.
Your electric bill increase is not just about the cost to charge but also about the efficiency of the vehicle. Teslas are known for their energy efficiency, meaning more miles per kWh than other electric cars.
This translates to a lower overall cost per mile, affecting how much your electric bill will rise due to your new Tesla.
Comparing Tesla Models by Cost to Own
When assessing the monthly cost of ownership consider both the initial price and the long-term charging costs.
The Tesla Model 3, being the most affordable option, starts with a lower price tag compared to the more premium Tesla Model S and the spacious Tesla Model X. Heres a quick look at their battery capacities and potential charging expenses:
- Tesla Model 3: Approx. 50-82 kWh battery capacity, average cost to charge $11-$18
- Tesla Model S: Approx. 100 kWh battery capacity, average cost to charge $23
- Tesla Model X: Approx. 100 kWh battery capacity, ideal for those needing an SUV, similar charging costs to Model S
- Tesla Model Y: Falls between Model 3 & X, combines efficiency and space, cost to own similar to Model 3 due to shared components
So if you charge a Model S from empty to full 20 times a month, you are looking at $460 being added to your electricity bill. But in real life, this figure would be lower because of the 20%-80% rule.
Your actual costs will vary based on local electricity rates and how often you charge.
Calculating Electricity Usage for Tesla
When considering the cost to charge a Tesla, youll need to understand the energy usage based on battery capacity and local electricity rates. This will help you estimate the increase in your electricity bill.
Cost Per Charge Calculation
To calculate the cost per charge for your Tesla, you must consider two main factors: your Teslas battery capacity (measured in kilowatt-hours or kWh) and your electricity rate (cost per kWh consumed).
For instance, a Tesla X with a 100kWh battery will cost different amounts based on the per kWh rate set by your electric company. If your electricity rate is $0.23 per kWh, a full charge would cost you [100kWh x $0.23/kWh] = $23.00.
Factors Affecting Charging Costs
Several factors affect charging costs including:
- The efficiency of your Tesla model
- The type of charger you use, such as a High Power Wall Connector (HPWC) which might use amps ranging from 40 to 80 amps
- Weather conditions which can impact your Teslas charging efficiency
- Electricity usage during peak hours can be more expensive, depending on your electric companys pricing scheme
- The frequency of charges, which depends on your typical mileage
Using energy during off-peak hours could result in savings on your electricity bill.
Comparing Tesla Charging to Gasoline Cost
If youre driving a gas car with an average of 25 mpg and gas costs $3.50 per gallon, a 100-mile trip would cost you $14.00.
Meanwhile, the same trip in a Tesla could cost less than $5, depending on your local electricity rates and your cars efficiency.
Impact on the Electric Bill
Upgrading to a Tesla can significantly change your electricity consumption patterns. Understanding how it affects your electric bill is essential for effective budget planning.
