How Many Batteries Are in a Tesla?

When it comes to the major part of Tesla i.e. its battery there arises a lot of questions. How many batteries are in a Tesla? How long does the battery last once charged? We are going to discuss everything related to this in this article. 

Tesla Inc. is a leading automobile industry well renowned for its commitment to sustainable transportation. A group of engineers including CEO Elon Musk, Tesla was established in 2003. Till now it is working continuously to meet its goals and vision.  

Since Tesla produces electric vehicles. It does not use the traditional combustion engines which use fossil fuels to propel the vehicle. Batteries are the heart of Tesla vehicles. These are the ones that power the vehicle. 

Tesla uses the battery to power systems like the air conditioner, radio, and extra systems in addition to starting the car, unlike other typical vehicles. Instead, the primary energy source for accelerating the car is batteries. 

Considering these factors it becomes quite obvious that the battery’s capacity, efficiency, and lifespan are key parameters that define the performance of an EV. 

The Tesla Battery: An Overview

If you are asking the question how many batteries are there in a Tesla car you might get surprised to know the answer. It is because it’s not just one or two, but thousands. 

Tesla uses a bunch of small batteries similar to those used in your laptop, but a bit bigger. They all work together and power the vehicle to run. The bundle of batteries so arranged together is called a “battery pack”.

So, to the question “How many batteries does a Tesla have?” The answer would be a whole lot!

But you might wonder why Tesla uses so many small batteries. This is because the bundle of batteries combined together helps to run the vehicle a longer distance on one charge, making them safer and also the battery last longer too. 

Talking about hybrid cars, the same question arises, “how many batteries are in a hybrid car?” Hybrid cars have just one battery but the size is much larger than any individual battery in Tesla. Hybrid vehicles have both the engines petrol engine and electric motors.                     

The number of battery cells varies with different models of Tesla. The heavier the vehicle is the more cells are required to power the vehicle. For instance, Tesla Cybertruck requires more cells than the Tesla Model X SUV. It is because Cybertruck is heavier than Model X.  

The table below shows the number of Li-ion cells in the Main battery of different models of Tesla.

Tesla Model S18650 Lithium-ion Battery7104 cells
Tesla Model S Plaid  Lithium-ion Battery7920 cells
Tesla Model 3 Standard Range2170 Lithium-ion Battery2976 cells

Tesla Model X Long Range PlusLithium-ion Battery8256 cells
Tesla Model Y4680 Lithium-ion Battery900 cells

So, while Tesla cars use thousands of small batteries, hybrids use one big one. And while both methods have their own advantages, Tesla’s approach is pretty unique. 

As we move forward, we’ll see how this innovative battery design impacts how many miles a Tesla can travel before needing a recharge and the lifespan of the batteries. 

How Many Miles Does a Tesla Last?

Each and every traveler once think about how much fuel we need to reach our destination while making a road trip. And everyone, in this case, wants a car that can cover a greater distance with limited fuel. Charge in terms of electric vehicles. 

How Many Miles Does a Tesla Last?

This led to an important question how miles does a Tesla last? 

The mileage of a car depends on lots of factors. In electric vehicles, such factors include how fast you’re driving, the weather, and how much weight the car is carrying. These parameters determine how far Tesla goes on one charge. 

But if you are talking on a normal day, the battery last quite longer on one charge. In figure, some Tesla models can go over 300 miles on a single charge. This is almost similar to driving from New York to Washington D.C. 

However different models of Tesla have different ranges:

Model S Plaid396 miles
Model S405 miles
Model 3 Performance 315 miles 
Model 3 Long Range 333 miles
Model 3 Rear-Wheel Drive272 miles
Model X Plaid333 miles
Model X348 miles
Model Y Performance303 miles
Model Y Long Range330 miles
Model Y All-Wheel Drive279 miles

Comparing the electric vehicles of Tesla with the regular traditional gasoline-engined car, the range of Tesla is impressive even not using any fuel. Generally, regular vehicles can travel between 300 to 400 miles on a full tank. This figure is almost equal to that of EVs. 

In terms of Performance, the electric vehicles of Tesla and other companies are competing with traditional engines. And electric vehicles have a great future over traditional cars either for the environment and performance. 

How Many Years Does a Tesla Battery Last?

On average, a Tesla battery can last between 10 to 15 years under normal usage. It is about 12,000 to 15,000 miles per year. This longevity, however, is not an arbitrary number. 

However, there are various factors that balance the longevity of the batteries. Those variables include charging habits, temperature management, and driving behavior. 

Tesla is continuously improving its vehicles through advancements in management systems, manufacturing processes, and of course its batteries chemistry. So now the number 10 to 15 years will be even more in the upcoming days. 

Voltage and Capacity

Batteries are the primary source of energy for electric vehicles. So the batteries are very strong. The battery can have power up to 100 kilowatts. (kW) which is equivalent to 100,00 watts. 

Talking about the voltage of the battery it is also pretty high. It is around 400 volts on average. While different models have different volts. 

More power and voltage can help a Tesla go further on one charge.

In simple terms, a Tesla battery is like a super strong, high-powered energy pack. It can take you really far before you need to recharge it.

Frequently Asked Questions(FAQs)

How long does a Tesla battery last?

According to the data by Tesla, on average the Tesla batteries last for about 22 to 37 years. But in practice, the batteries almost loses is capacity and quality after 15 years of use. 

How much does it cost to replace a Tesla battery?

The cost of Tesla batteries ranges from $12,000 to $20,000. This is quite a huge number but it includes the labour cost and other parts as well. The cost of batteries alone is around $7,000 to $14,000 for the Model S, which is the cheapest one. 

Are there 2 batteries in a Tesla?

In each Tesla model, there are 2 batteries, one primary large battery which provides an energy source to propel the vehicle, and another 12-volt battery. The small battery controls the system of the car such as computers, unlocking the door, and charging control of the main battery.
