Factors That Affect the Cost of Charging a Tesla

Before diving into the nitty-gritty of charging costs, it’s essential to understand the key factors that influence how much you’ll pay to keep your Tesla’s battery topped up.

The Tesla Model You Own

Tesla offers a range of models, each with different battery sizes and capacities. The larger the battery, the more it will cost to charge it from empty to full. Here’s a quick overview of the battery sizes for Tesla’s current lineup:

Model 3: 50 kWh (Standard Range) or 82 kWh (Long Range)
Model Y: 75 kWh (Long Range) or 82 kWh (Performance)
Model S: 100 kWh
Model X: 100 kWh
Cybertruck: 100 kWh (Single Motor) or 200 kWh (Tri Motor)

As you can see, the Cybertruck’s tri-motor variant has the largest battery capacity, meaning it will cost more to charge from empty to full compared to other Tesla models.

Where You Charge Your Tesla (Home vs Public Charging Stations)

One of the most significant factors influencing charging costs is where you charge your Tesla. There are two main options: charging at home or using public charging stations.

Charging at Home

Charging your Tesla at home is typically the most cost-effective option. You’ll need to install a dedicated home charging station, which can cost anywhere from $450 to $1,500 or more, depending on the specific installation requirements. However, once installed, you’ll only pay for the electricity used to charge your Tesla based on your local residential electricity rates.

Most Tesla owners opt for overnight charging at home, taking advantage of off-peak electricity rates, which can be significantly lower than peak rates. For example, in California, Pacific Gas and Electric Company (PG&E) offers an EV rate plan with rates as low as $0.12 per kWh during off-peak hours.

Public Charging Stations

While more convenient for charging on the go, public charging stations tend to be more expensive than charging at home. There are two main types of public charging stations: Tesla’s Supercharger network and third-party charging networks.

Tesla Superchargers Tesla’s proprietary network of Superchargers is designed for fast charging on long trips. The cost of using a Supercharger varies depending on your location and the charging rate, but it typically ranges from $0.25 to $0.50 per kWh. This means a full charge for a Tesla Model 3 Long Range could cost anywhere from $20 to $40 at a Supercharger.
Third-Party Charging Networks In addition to Tesla’s Supercharger network, there are numerous third-party charging networks available, such as ChargePoint, EVgo, and Electrify America. These networks often have different pricing structures, with costs ranging from $0.30 to $0.60 or more per kWh, depending on the location and charging speed.

Some businesses, such as hotels, shopping malls, and certain retailers, offer free charging stations for customers, which can be a great way to top up your Tesla’s battery while you’re out and about.

Time of Day for Charging

As mentioned earlier, electricity rates can vary significantly based on the time of day. Most utility companies offer lower rates during off-peak hours, typically overnight and on weekends, when electricity demand is lower.

Charging your Tesla during off-peak hours can result in significant savings, especially if you charge at home. For example, if your local utility offers a rate of $0.10 per kWh during off-peak hours and $0.25 per kWh during peak hours, charging your Tesla overnight could save you up to 60% compared to charging during the day.

Even some public charging stations offer discounted rates during off-peak hours, so it’s worth checking the pricing structures before you charge.

Location and Electricity Rates

The cost of electricity can vary significantly depending on your location. In the United States, residential electricity rates range from as low as $0.10 per kWh in Louisiana to as high as $0.34 per kWh in Connecticut, according to data from the U.S. Energy Information Administration.

These regional differences in electricity rates can have a substantial impact on the cost of charging your Tesla at home. For example, fully charging a Tesla Model 3 Long Range at home in Louisiana would cost around $9, while the same charge in Connecticut would cost approximately $32.

Public charging station rates are also influenced by local electricity costs, so you may find that charging your Tesla at a public station in a high-cost electricity area is more expensive than in a low-cost area.

Cost Comparison: Charging a Tesla vs Fueling a Gas Car

One of the primary advantages of owning an electric vehicle like a Tesla is the potential cost savings compared to a gasoline-powered car. Let’s take a closer look at how the costs of charging a Tesla stack up against fueling a gas car.

To make an accurate comparison, we need to consider the following factors:

Average annual mileage
Fuel efficiency of the gas car
Cost of gasoline in your area
Cost of electricity in your area
Potential upfront costs for home charging installation (if applicable)

Let’s assume an average annual mileage of 12,000 miles and compare the costs for a Tesla Model 3 Long Range and a compact gasoline car with an average fuel efficiency of 30 mpg.

Charging a Tesla Model 3 Long Range

Battery capacity: 82 kWh
EPA-rated range: 358 miles
Annual electricity usage: 3,360 kWh (12,000 miles / 358 miles per charge * 82 kWh)

In a low-cost electricity area like Louisiana ($0.10 per kWh), charging the Tesla Model 3 Long Range at home would cost:

3,360 kWh * $0.10/kWh = $336 per year

In a high-cost electricity area like Connecticut ($0.34 per kWh), the annual cost would be:

3,360 kWh * $0.34/kWh = $1,142 per year

Fueling a Gasoline Car

Assuming an average gas price of $3.50 per gallon and a fuel efficiency of 30 mpg, the annual fuel cost for the gasoline car would be:

12,000 miles / 30 mpg * $3.50/gallon = $1,400 per year

Even in a high-cost electricity area like Connecticut, charging the Tesla Model 3 Long Range is still cheaper than fueling the gasoline car. And in a low-cost electricity area like Louisiana, the savings are substantial – over $1,000 per year.

Keep in mind that this comparison doesn’t account for potential upfront costs for home charging installation or fluctuations in gas prices, which can significantly impact the overall cost of ownership for both vehicles.

Ways to Reduce Tesla Charging Costs

While charging a Tesla is generally more cost-effective than fueling a gas car, there are several strategies you can employ to further reduce your charging expenses.

Install Solar Panels

Installing solar panels at your home can significantly reduce or even eliminate the cost of charging your Tesla. With solar panels, you can generate your own renewable electricity and charge your Tesla using that clean energy source.

The upfront cost of installing a solar panel system can be significant, but many states and utility companies offer incentives and rebates to offset the initial investment. Additionally, the long-term savings on your electricity bills can make solar panels a worthwhile investment, especially if you plan to own your Tesla for several years.

Utilize Off-Peak/Night Time Rates

As discussed earlier, taking advantage of off-peak or night-time electricity rates can result in substantial savings when charging your Tesla at home. Many utility companies offer special rate plans or time-of-use rates specifically designed for EV owners, allowing you to charge your Tesla at significantly lower rates during off-peak hours.

Be sure to check with your local utility company to see if they offer any special EV rate plans or time-of-use rates that can help you save on charging costs.

Take Advantage of Free Public Charging

While public charging stations generally cost more than charging at home, many businesses and establishments offer free charging as an incentive for customers. Look for free charging stations at shopping malls, hotels, restaurants, and other retail locations.

Apps like PlugShare and ChargePoint can help you locate free charging stations in your area. Additionally, some workplaces may offer free or discounted charging for employees, so it’s worth inquiring about this perk.

Consider an Electricity Plan Optimized for EV Owners

In addition to special EV rate plans from your local utility company, some third-party electricity providers offer plans specifically designed for EV owners. These plans often include lower rates during off-peak hours, making them ideal for overnight charging at home.

Do your research and compare different electricity plans in your area to find the one that offers the best rates for EV charging.

Charge Mainly at Home vs Public Stations

Whenever possible, try to charge your Tesla at home rather than relying on public charging stations. While public charging can be convenient for longer trips or when you need a quick top-up, it’s generally more expensive than charging at home, especially if you take advantage of off-peak rates.

Plan your charging routine around charging at home as much as possible, and use public charging stations only when necessary.

Is the Tesla Charging Network Free?

One common misconception about Tesla is that their charging network, known as the Supercharger network, is free for all Tesla owners. However, this is not entirely accurate.

In the early days of Tesla, the company offered free unlimited Supercharging as an incentive for early adopters. However, as Tesla’s sales grew, this became unsustainable, and the company had to adjust its charging policies.

As of 2023, most new Tesla models no longer come with free unlimited Supercharging. Instead, Tesla owners have to pay the standard Supercharger rates, which range from $0.25 to $0.50 per kWh, depending on the location and charging rate.

However, Tesla does occasionally offer free or discounted Supercharging as part of promotional campaigns or referral programs. For example, in 2023, Tesla offered one year of free unlimited Supercharging for customers who purchased a new Model 3 or Model Y during a specific promotional period.

It’s important to note that while Supercharging is no longer free for most Tesla owners, it’s still generally more affordable than fueling a gasoline-powered car, especially when charging at home.

Closing Thoughts

Charging a Tesla can be a cost-effective alternative to fueling a gasoline-powered vehicle, especially when taking advantage of home charging and off-peak electricity rates. While the upfront cost of installing a home charging station may seem daunting, the long-term savings on “fuel” costs can make it a worthwhile investment.

The cost of charging a Tesla varies depending on several factors, including the model you own, where you charge, the time of day you charge, and your local electricity rates. By understanding these factors and employing strategies like installing solar panels, utilizing off-peak rates, and taking advantage of free public charging, you can significantly reduce your charging expenses.

Ultimately, the decision to purchase a Tesla should be based on more than just the cost of charging. Factors such as environmental impact, performance, and overall ownership experience should also be considered. However, with the potential for substantial long-term savings and the convenience of charging at home, the cost of charging a Tesla can be a compelling reason to make the switch to electric vehicles.
