Tesla Model Y Battery and Charging

Let’s talk about the Tesla Model Y’s battery and charging. The car has two battery options: the Long Range Battery (75 kWh) and the Performance Battery (82 kWh). These batteries are like lots of small batteries put together to make a big one.

The car runs on electricity stored in these batteries. We measure the battery’s size in kilowatt-hours (kWh). It’s important to know because it affects how far the car can go and how fast it can go.

When it’s time to charge your Tesla Model Y, you have different options. I’ll explain those soon. But first, remember that understanding kWh is the key to making the right choice for your electric car.

1. Battery Capacity: Measuring it in kWh

I’ve been learning about electric cars lately, and one key thing to know is battery capacity. It’s measured in kilowatt-hours (kWh), a unit of energy. Think of it like a 1,000-watt device running for an hour – it uses 1 kWh of energy.

For Tesla Model Y, the battery capacity is stated in kWh. Why is this important for electric cars? Because it tells us how much energy the battery can hold.

Put simply, higher kWh means more stored energy, which means your car can go further on a single charge. When choosing an electric car, just make sure the kWh rating matches your driving needs.

2. Charging Methods: Home, Supercharging, and More

Let’s take a look at the charging options for the Tesla Model Y, making it simple for everyone to understand.

Home Charging

The most common method is charging at home using a Wall Connector. It can charge your car at a rate of up to 44 miles per hour, but you’ll need a 240-volt outlet and might require an electrician’s assistance.


When you’re on the road and need a quick recharge, Tesla’s supercharging stations come in handy. These stations are found along highways and in cities and can provide around 170 miles of range in just 30 minutes.

Destination Charging

Tesla has partnered with various businesses, like hotels and restaurants, to offer Destination Charging stations at popular spots. These let you charge your car while you’re out and about.

How Many kWh Are Needed to Charge a Tesla Model Y?

Electric cars, like the Tesla Model Y, are fascinating. But how much energy (measured in kilowatt-hours or kWh) do you need to charge one up?

1. Battery Size

The Tesla Model Y comes with two types of batteries: Long Range and Performance. Think of the battery as a fuel tank. The bigger the tank, the more energy you need to fill it up.

Now, how you charge your car also affects the energy needed. Charging at a supercharger station can be thirstier than charging at home. Different charging methods have different appetites for kWh.

Your driving style matters too. If you zoom around a lot and crank up the A/C or heated seats, you’ll use more energy. Weather matters, too. Cold weather can shrink the battery’s capacity, while hot weather can make it work harder.

According to EnergySage, if you own a Tesla Model Y with the Long Range Battery and aim to charge it from 0% to 100%, you’ll need approximately 91 kWh. [1] However, keep in mind that it’s best not to fully charge your battery regularly to preserve its lifespan. For those with a Tesla Model Y equipped with the Performance Battery, you’ll need around 92 kWh.

It’s important to note that the kWh needed for charging can vary based on your chosen charging method. Charging at a supercharging station generally demands more kWh compared to charging at home.

Cost of Charging a Tesla Model Y per kWh

The cost of charging your Tesla Model Y per kWh can differ based on where you live and local electricity prices. However, the national average in the United States hovers around $0.13 per kWh.

To get a rough estimate, let’s say you have a Tesla Model Y with a 75 kWh battery. Charging it from 0% to 100% would require approximately 75 kWh. At $0.13 per kWh, the cost would be roughly $9.75 for a full charge.

Tips for charging a Tesla Model Y Efficiently

Charging your Tesla Model Y right can save money and boost battery life. Here are some simple ways to do it:

1. Don’t Overcharge

Charging your Model Y to 80% is good for the battery. Only go for a full charge when you really have to.

2. Use Regenerative Braking

Model Y’s regenerative braking turns braking energy into power for the battery, saving energy and making the battery last longer.

3. Plan Your Charges

Plan your charging stops ahead of time for long drives. This ensures you’ll always have enough charge for your trip.

4. Off-Peak Charging

Charge during off-peak hours to save money. Some providers offer lower rates at these times, and it’s also better for the environment.

What is the Charging Time of a Tesla Model Y?

Knowing how long it takes to charge a Tesla Model Y is important for practical planning. Let’s get to the point:

1. Home Charging

Charging at home using a standard 120-volt outlet takes time. It can be up to 75 hours for a Long Range Battery (75 kWh) and up to 82 hours for a Performance Battery (82 kWh). That’s because the standard outlet gives a slower charge rate of about 3–5 miles per hour.

2. Level 2 Charging

Level 2 charging is faster. It takes around 11–12 hours for a Long Range Battery (75 kWh) and 12–13 hours for a Performance Battery (82 kWh) when using a 240-volt charging station at home or a public one.

3. Supercharging

Supercharging is the quickest way to charge your Model Y. It can give you up to 170 miles of range in only half an hour. For a Long Range Battery (75 kWh), it’s about 45–50 minutes to charge from 10% to 80%. And for a Performance Battery (82 kWh), it takes around 50–55 minutes. But remember, charging times can differ depending on the supercharging station you choose.

Tips for Reducing Charging Time

Reducing your Tesla Model Y’s charging time is vital for a quick, cost-effective charge. Here are simple tips:

1. Charge Early

Don’t wait until your battery is nearly empty. Charging earlier can save time and make your trips smoother.

2. Choose Supercharging

On long trips, supercharging is your best bet for quick charging. Find Supercharging stations along your route.

3. Consider a Level 2 Charger

At home, a Level 2 charger is more efficient than a standard outlet. It significantly quickens the charging process.
