Formula For Calculating The Charging Speed Of The Tesla
There is a simplified formula by which you can calculate the speed of the charging process of an electric car:
Duration = Auto battery capacity x 1000 / EVSE power x 1000.
For example, with a Tesla battery capacity of 82 kWh and a charging power of 6.5 kW, the car will need the following charging time:
Duration = 82000/6500 = 12.6 hours.
These are approximate figures, and for more accurate results you need to use a calculator. This tool is sure to take into account the 10% loss of energy as well as the characteristics of the built-in charging unit.
How Do You Charge A Tesla
There are four options for charging:
Regardless of the charging method you use, you simply plug into the Tesla charging port and charging will start automatically.
How To Charge A Tesla At Home
Level 1 charging stations can be plugged straight into a standard 120V outlet in your home or garage. While Level 1 systems have the ability to get the job done, they are the least efficient way to charge your EV and can take as long as 3 days to fully charge a Tesla. This painfully slow charging rate often leads a Tesla vehicle owner to depend on the Tesla public charging Supercharger network or install a home EV charger of their own.
The second home charging option for a Tesla EV driver is a Level 2 charging station that puts out the recommended 240 volts that are needed to charge your Tesla. Level 2 charging systems plug into a dedicated 50 amp circuit that may require professional electrical installation. With significantly more power than a level one charging station, Level 2 chargers can charge your Tesla roughly 6 times faster. The maximum rate at which a Tesla can charge is between 7.2kW-11.5 kW, depending on the Tesla model. So how many kWh to charge a Tesla exactly? Teslas have a battery capacity ranging from 50 kWh on the standard range Model 3 to a whopping 100 kWh that powers all Model S and Model X packages.

The Model S has a 100 kWh battery and can be charged with a variety of EV chargers. Electric vehicles can be charged with a 120-volt Level 1 charger or a 240-volt Level 2 charger as well as DCFC stations.
How Fast Does A Supercharger Charge A Tesla
The most frequent question for electric vehicle owners is How long does it take to charge? In a previous post titled The Reality of Charging an EV on the Road, I discussed the three categories of charging .
As a Tesla owner, the next set of questions almost always have to do with Supercharging. While I talked a lot about where to find Superchargers and generally how they work in the previous post, I only touched briefly on the factors affecting charging speed. I said:
L3: fast charging is typically 50 kW or greater. Teslas superchargers are capable of about 120 kW at peak rates. With L3 charging, a 60 kWh battery can be fully charged in an hour or so. A special note: L3 chargers adjust their power levels based on temperature, battery capacity, battery state of charge, and other factors to protect the battery. L3 chargers provide peak power when the battery is warm and nearly empty. Charging at L3 rates is an intricate dance between the electrical grid, car, and charger.

What About A Tesla Supercharger
Today, Tesla has more than 12,000 Superchargers across North America, Europe, and Asia. In March, Tesla unveiled its V3 Supercharging, which enables Tesla electric vehicles to charge faster than any other electric vehicle on the market today. For example, a 2019 Model 3 Long Range vehicle operating at peak efficiency can recover up to 75 miles of charge in 5 minutes when using their electric vehicle charging stations and charge at rates of up to 1,000 miles per hour. It also introduced a new feature called On-Route Battery Warmup, which allows your car to intelligently heat the battery when approaching a Tesla Supercharger in order to ensure its EV drivers charge at the optimal temperature and ultimately reduce average charge times for owners by 25 percent.
Other Tesla Supercharging stations charge with up to 150 kW of power distributed between two cars with a maximum of 150 kW per car, depending on the version. These electric vehicle charging stations take about 20 minutes to charge to 50%, 40 minutes to charge to 80%, and 75 minutes to 100% on the original 85 kWh Model S.

How Much Does It Cost To Charge A Tesla At Home
If you charge at home, the local cost of electricity will determine your overall charging cost. The average utility rate in the US was about 13.72 cents per kWh as of March 2022.
To calculate the home charging cost, multiply the capacity of your battery by your utility’s cost per kWh.
For example:
- Electricity rate = $0.1372 per kWh
- Charging cost = 75 times $0.1372 = $10.29 for a near-empty battery fill-up.
How Can I Charge My Tesla At Home
There are two main options for charging up your vehicle at home. With a Level 1 charging station that is plugged into a standard 120V outlet in your home or garage charging up the vehicle could take up to 3 days! While this might be sufficient for some people who do not regularly need to drive, the majority of people who drive to and from work every day would need a different solution.
The second option for home charging is a Level 2 charging station that puts out 240 volts. Level 2 systems offer significantly more power than a level 1 charger. Level 2 chargers have the ability to charge a Tesla 6 times faster than a Level 1 charger.

How Long Does It Take To Charge A Tesla On 240v
Level 2 AC chargers are commonly found in your home to charge large appliances like dryers or fridge/freezers, or garages. They do often need to be installed by a professional electrician but it is a fairly easy process.
Level 2 AC chargers are the most common type of charge found in Destination Charging locations, although DC fast chargers are becoming increasingly common.
At home, Level 2 240V plugs offer approximately 40 amps but it is possible for them to go as high as 80. You can expect your Tesla vehicle to take between eight and 12 hours to reach fully charged.
Power Strips And Extension Cords
Youâll need to use an extension cord with the right wire gauge to charge a Tesla from the wallâdonât bother with thin cheap hardware store cords.
Extension cords arenât really regulated much in the United States. This is interesting, as extension cords are a common source of overheating problems and electrical cords.
Tesla wants you to think of power like water, in the sense that large pipes enhance flow rates while small pipes restrict it. But hereâs a big differenceâsmall gauge cords, when subjected to excessive power load, get extremely hot.
Additionally, they cause resistance which reduces the speed at which your Tesla charges. Thatâs why itâs essential to read the label and find a cord with the proper wire gauge for charging your Tesla.
In the United States, the color or shape of an extension cord denotes nothing. Many âheavy-dutyâ orange or green cordsâlike the ones you see at concerts and on construction sitesâare actually the same as the thin white ones, and the gauge is too thin for charging a Tesla.
Wire gauge values are inverse to wire thickness. That means 18 gauge is thinner than 14 gauge, which is thinner than 12 gauge, and so on. Next, weâll cover the wire gauge you should look for when choosing an extension cord for charging your Tesla.
If youâre charging with a 15 amp current, use a ten or 12-gauge extension cord. For more powerful 20 amp charging, use a 10-gauge cord or heavier.
