**How many kWh to charge a Tesla? **As electric cars become more popular, many people are wondering about the cost of charging them. Tesla, one of the most popular electric car manufacturers, has a range of models that require a different amounts of electricity to charge.

Supercharger stations, which are Tesla’s proprietary charging stations, cost an average of $0.28 per kWh, which means that it costs approximately $20 to $30 for a full charge, based on the model. Supercharger stations can be found in over 70 countries around the world. Let’s get into the nitty-gritty of how much it costs to charge a Tesla, including the variables that influence the price as well as the formula for determining it.

## Introduction to EV charging

There are three levels of charging an EV: Level 1, Level 2, and DC fast charging.

### Level 1 AC charging

Level 1 is the simplest and slowest. It uses your standard 120-volt wall outlet at home, so you can only get between 3-6 miles of range per hour. This could be enough for routine battery top-ups, but a full charge can take days.

### Level 2 AC charging

Level 2 uses the same 220V plug as that of large home appliances. This is the popular choice for home charging because it can give you up to 50 miles of range per hour. It can possibly fully charge your electric vehicle overnight!

Both Level 1 and Level 2 can be used for Tesla charging at home.

### DC fast charging

Tesla has a network of proprietary fast chargers called the Tesla Supercharger, which uses a 480-volt direct current technology to give you up to 322 miles of range in just 15 minutes of charging. The set-up is complicated and requires an electrician, so DC chargers like Tesla Superchargers are not typically used for home charging. You’ll have to check your nearest charging station for available DC chargers.

## How many kWh to charge a Tesla?

The number of kWh required to charge a Tesla depends on the battery capacity of the car and the charging rate. As a general rule, a Tesla Model 3 or Model Y with a Long Range battery pack requires approximately 75 kWh to charge from empty to full, while a Standard Range model requires around 55 kWh.

The usable capacity of a Long Range Model 3 is 75 kWh. With a standard 11.5 kW home charger, it will take 6 hours and 31 minutes to go from 0% to 100% using this simple calculation:

Charging Time = Battery Capacity / Charging Wattage = 75 kWh / 11.5 kW = 6.52 Hours

## Battery size

Tesla vehicles come with different battery sizes, ranging from 50 kWh to 100 kWh. The larger the battery size, the more electricity it will require to charge. For instance, a Model S with a 75-kWh battery will require more electricity than a Model 3 with a 50-kWh battery.

## Charging speed

The charging speed also affects the amount of electricity required to charge a Tesla. There are different types of chargers, ranging from 120-volt outlets to high-speed Superchargers. The faster the charger, the more electricity it will consume. However, faster charging can also save time and reduce the overall cost of charging.

## Primary factors influencing EV charging

There’s no fixed rate in charging an electric vehicle. The cost will vary depending on several factors. Here are some of the things Tesla owners should consider for maximum EV savings:

### State of charge and depth of discharge

Depth if Discharge (DoP) helps you know how much of your EV’s battery capacity can be used and how long it will last. DoP refers to the amount of battery that has been discharged relative to the total electrical energy supply available. It seems complicated, but it’s actually pretty simple to understand. To put it into perspective, discharging 16 kilowatt hours from a 40-kilowatt hour EV battery means the DoP is 40% (16 kWh / 40 kWh).

State of Charge (SoC) is its complete opposite. It refers to the percentage of battery still available for use. Using our example earlier, a 40 kWh EV battery with a 40% DoP has a state of charge of 60%, or 24 kWh.

**Understanding electricity consumption**

Before we dive deeper into the electrical consumption, let’s do a quick review of some terms:

**Current**, measured in amperes (amps), refers to the flow of electricity in a circuit. The higher the amperage, the more electricity can flow.**Voltage**, measured in volts (v), refers to the pressure that pushes electricity. The higher the voltage, the higher the pressure, which means faster charging times.**Power**measures the rate of energy transfer. It can be derived by multiplying current and voltage. So, when looking at your electricity bill, your monthly consumption is measured in kilowatt hours (kWh).

## How much does it cost to charge your Tesla

This may come as a surprise to potential Tesla owners, but these cars use a small amount of electricity despite the powerful features.

An average Tesla electric car uses around 34 kWh of electricity per 100 miles. That’s 34,000 kWh per 100,000 miles, or up to 170,000 kWh throughout the car’s lifespan. With a charging efficiency of about 94% and a discharge efficiency of 90%, the electricity used by a Tesla battery is remarkably low, so you won’t have to worry about your electric bill ballooning.

Based on the national average cost of electricity, charging your Tesla only costs $13.96. That’s about $0.05 per mile across all models. So, a Tesla Model X costs about $18.30 to fully charge, while a Model S is not too far behind at $18.29. Model 3 is the cheapest to charge at $9.62, and a full charge of a Model Y costs $13.58.

### Tesla battery capacity

Tesla EVs have some of the highest battery capacities on the market. It is measured using the kWh (kilowatt-hours) unit, while the charge of a battery is measured using the mAh (milliamp hours) unit.

A Tesla battery is made of thousands of individual lithium-ion cells. These cells range from 3400 mAh to 5000 mAh in charge, giving a total storage capacity between 85 kWh to 100 kWh.

## Factors that can affect charging

While the above calculations give a rough estimate, there are many factors that can affect the actual cost of charging a Tesla. These factors include:

- Time of day: Some electric utilities charge different rates depending on the time of day. Charging during off-peak hours can be cheaper.
- Location: The price of electricity can vary depending on your location. In some areas, the price may be higher or lower than the national average.
- Charging Speed: As mentioned earlier, faster charging can save time but also consume more electricity. If you are in a rush and need to charge quickly, you may have to pay more.
- Battery Health: Over time, the battery capacity can degrade, which can affect the amount of electricity required to charge. If your battery is not holding as much charge as it used to, you may need to charge more frequently or for a longer time.

In addition to these factors, the type of charger you use can also affect he overall cost. Tesla has its own network of Superchargers, which offer the fastest charging speeds but can be more expensive than other types of chargers. There are also third-party charging networks that offer different pricing models. Hence, it is important to do your research and find the best option for your needs.

## Is charging a Tesla cheaper than gas?

With the current average gas price at $3.28 a gallon, it would cost around $45 to fill up a 12-gallon car tank.

For a car that gets 30 miles of range per gallon, a full tank would give it 360 miles of range.

Driving an average of 1,183 miles per month means having to refuel more than three times a month and spending around $144. In comparison, driving the same range with a Tesla would only cost about $59.15. That’s a 40% increase!
