If you’ve heard of Tesla, you’ve probably also heard of the company's high-powered Superchargers. To get technical, Tesla Superchargers are 480-volt direct current (DC) fast chargers. But more simply, Superchargers are just really fast electric vehicle battery chargers.

Thanks to Superchargers, Tesla owners don’t have to worry about running on empty because their EV is programmed to plan routes with Superchargers along the way. And the fact that Superchargers can charge at a rate of up to 11 miles per minute doesn’t hurt either. By having an extensive fast-charging network, Tesla has effectively cured consumers' biggest fear about electric cars - running out of battery. 

Despite there being well over 40,000 Superchargers installed globally, there’s still a bit of confusion about how they work, how much they cost, and who can use them. We’re here to pull back the curtain on Superchargers, so you can get a better understanding of what these fast chargers are all about.

    How do Superchargers charge Tesla batteries so fast?

    Tesla car batteries have something called an “onboard charger”. Onboard chargers convert alternating current (AC) electricity coming from a charging source to DC energy. DC energy is what the battery needs in order to charge. 

    Unlike other EV chargers, Tesla’s Superchargers release DC electricity, so the onboard charger is bypassed and the DC energy directly charges the battery. Because the electricity is going straight to the battery and doesn’t have to pass through the onboard charger, the vehicle can be charged faster

    Charging an EV does take a bit longer than getting a tank of gas, but Superchargers are conveniently located near shopping centers and downtown urban areas, so there’s plenty to do while you're plugged in.

    Superchargers aren't Tesla’s only charging stations. Tesla also has Destination Chargers, which take longer to charge. Destination Charging is most useful for overnight or prolonged stays during long-distance traveling, as it can take a few hours to completely charge your battery. 

    You can also use non-Tesla charging stations, like ChargePoint stations, as long as you have your charging adapter (which comes with your Tesla) on hand. 

    How can I find Superchargers near me?

    One of the best functions of a Tesla is its built-in Trip Planner. Trip Planner works just like a regular GPS system, but it maps your route, so you pass through Supercharger stations along the way to your destination. 

    It also tells you how long you should stop and charge for at each station to get to your destination as quickly as possible without running out of charge. 

    Trip Planner makes it incredibly easy to keep your EV charged up on any road trip.

    How long does it take to charge a Tesla with a Supercharger?

    A Supercharger can charge a battery from 0% to about 50% in 15 minutes. The actual charging rate will vary depending on the Tesla model you have, the actual charger you’re using, and how much power is already in your battery. That being said, completely charging your Tesla from 0% to 100% using a Supercharger would take roughly 70 minutes.

    The following table outlines Supercharging speeds for the four Tesla models:

    Tesla Model Supercharger speed
    Model 3 Up to 175 miles in 15 minutes
    Model Y Up to 162 miles in 15 minutes
    Model S Up to 200 miles in 15 minutes
    Model X Up to 175 miles in 15 minutes

    Even with a Supercharger, charging your Tesla is going to take longer than it would be to fill up a tank of gas. However,  you can plan out charging times to coincide with meals or sightseeing stops you want to make on your way to your destination.

    Can I charge with a Tesla Supercharger for free?

    There is a lot of confusion around whether or not Supercharging is free. For most Tesla vehicle owners, Supercharging is not free

    Tesla launched a bunch of campaigns in the past that gave some customers free Supercharging for life. The company hasn’t launched a campaign like this for quite some time. But, for those who did get to enter one of these programs, it was a pretty sweet deal. 

    Here are some of Tesla’s vehicles that may qualify for some form of free Supercharging: 

    • Model S’s released between 2012 and 2020, except for the Model S 40
    • The Model 3 Performance versions released between 2018 and 2019 may have free unlimited Supercharging, but they can only be used by the original owner. If bought used, the free Supercharging offer is voided
    • Tesla models delivered between December 15 and December 31, 2022, may have 10,000 miles of free Supercharging.

    You can check to see if your Tesla qualifies for any sort of free Supercharging promotion through your Tesla account. Simply log in, click Manage, then View Details on your Tesla vehicle, and see if “Free Unlimited Supercharging” is listed. You can also call Tesla’s customer service directly. 

    How much does it cost to charge with a Supercharger?

    The true cost of charging a Tesla depends on several variables, which we break down in our video below.

    The cost of charging your Tesla varies between Supercharging stations, but generally, you can expect it to cost about $25 to completely charge your battery from 0% to 100% using a Supercharger. Not only is this cleaner than a tank of gas, but it’s also cheaper, too! 

    There are two different ways you can be billed at a Supercharger: per kilowatt-hour (kWh) or per minute. When you select a Supercharging station with the Trip Planner, you can see which billing structure the station uses and what prices they charge ahead of time. 

    Per-kWh Supercharging 

    Most Superchargers use per-kWh billing, meaning you will be billed for each kWh of electricity used to charge your battery. 

    The pricing per-kWh is different at each Supercharging location, but it’s typically around $0.25 per kWh. 

    Per-minute Supercharging 

    Per-minute Superchargers are less common than per-kWh chargers. Typically, you’ll only find per-minute chargers in states where there are regulations in place that prevent any entity besides a utility from selling electricity by the kWh. 

    Per-minute charging stations offer four different rates: 

    • Tier 1 rates are the lowest rates and are applied when cars are charging at or below 60 kilowatts (kW).
    • Tier 2 rates are applied when cars are charging above 60 kW but below 100 kW, and are the second-lowest rate.
    • Tier 3 rates are applied when charging above 100 kW below 180 kW and are the second highest rate per minute.
    • Tier 4 rates are the highest price per minute and are used when charging above 180 kW.

    Idle fees can drive up your costs 

    Tesla charges idle fees to drivers who remain parked at a Supercharger after their vehicle is fully charged, if the station is more than 50% full. The idle fee is charged per minute, so the longer you remain at the station, the higher the fee will be. Idle fees vary between locations. 

    Luckily, the Tesla app alerts you when your car is done charging so you can move it right when it’s finished. If you move your car within five minutes of being notified that your charge is complete, the idle fee will be waived. 

    Who can use a Tesla Supercharger?

    Tesla Superchargers are available exclusively to Tesla vehicle owners; Superchargers are equipped with a Tesla-specific charging connector. 

    In July 2021, Tesla CEO Elon Musk announced that the Supercharging network will be open for use to non-Tesla electric vehicles by the end of the year, regardless of whether or not they were manufactured by Tesla.

    So far, this has only been rolled out as a pilot program in countries outside of the U.S. Hopefully, the network opens up in the U.S. in the near future.

    Is it cheaper to charge with a Supercharger or charge at home?

    In almost all cases, charging your Tesla at home is going to save you the most money since Superchargers tend to bill at a higher rate per kWh than your utility does. 

    Depending on the model you have, it will cost between $10.49 to $17.55 to completely charge your Tesla at home.

    Cost savings aside, you’ll probably want charging at home to be your main source of charging anyway. Why? It’s better for your vehicle. Superchargers send an incredible amount of high-voltage electricity right to your battery, which can cause damage if it’s done on a regular basis. 

    So, not only will you save money by charging at home, you’ll save your battery life, too.

    The cheapest way to charge a Tesla is with solar

    No matter how you slice it, charging your Tesla is going to be cheaper than filling up a tank of gas. But, using solar power to charge your Tesla makes it even cheaper. You can install enough solar panels on your roof to cover your home’s electricity needs and to charge your EV.

    Yes, installing solar panels is a pretty substantial upfront investment, but that’s really the only thing you have to pay for once they’re installed. When you divide the cost of the installation over how much electricity it will produce across the lifetime of the system (25 years), each kWh of electricity will only cost about $0.11.

    In 25 years, electricity from the grid is projected to cost an average of $0.29 per kWh, so installing solar sooner rather than later is your best bet if you want to lock in your savings. So, you end up spending way less on electricity to charge your Tesla over time with solar than if you just used electricity from the grid. 

    Plus, there are various incentives and rebates on the federal, state, and utility levels - check out our solar incentives guide to see which you may qualify for.
