Everything you need to know about Tesla vehicle batteries: functions and innovations
Composition and technology of Tesla batteries
Batteries Tesla are distinguished by their innovative composition and cutting-edge technology. The Nickel-Cobalt-Aluminium (NCA) offers an ideal balance between energy density, durability and cost, guaranteeing autonomy and longer life. With a graphite anode, Tesla batteries offer high storage capacity without compromising safety or durability.
The use of a liquid electrolyte facilitates the efficient movement of lithium ions, contributing to optimum performance of the battery. battery. In addition, advanced software-based battery management controls temperature, optimises charging and discharging, and ensures safe and efficient use of stored energy.
Overall, the sophisticated composition and advanced technology of Tesla's batteries illustrate the company's commitment to pushing the boundaries of electric mobility and shaping the future of the automotive industry.
Tesla batteries over time
Since its beginnings in 2008, Tesla has placed innovation at the heart of its development, particularly when it comes to batteries. In its quest for greater autonomy, performance and durability, the brand has achieved some remarkable milestones:
- Energy density multiplied by 5 : allowing increasing autonomy for each kWh of battery.
- Optimised chemistry : from NCA to NCM, for improved performance and stability.
- Innovative format: with the 4680 tabless battery, reducing costs and increasing efficiency.
These advances have resulted in electric vehicles that are ever more efficient and affordable, constantly pushing back the boundaries of technology.
Tesla is not stopping there and is continuing to explore new avenues: Optimised thermal management, increased durability, efficient recycling... The aim is clear: to offer ever more powerful batteries that are environmentally friendly and accessible to as many people as possible.
How long does a Tesla battery last?
As charging and discharging cycles accumulate, the performance of electric vehicle batteries naturally declines. The lifespan of a battery can therefore be estimated on the basis of the number of charge cycles, which is generally between 1,000 and 2,000.
Nevertheless, manufacturers often prefer to express their battery warranties in terms of kilometres driven or years, offering another perspective on their longevity. Tesla, for example, guarantees its batteries for 8 years or between 160,000 and 240,000 km, depending on the model.
Tesla, Elon Musk's brand, continues to strive for excellence in the electric vehicle market by constantly improving its performance. The company regularly publishes reports on its environmental impact, providing valuable information on the actual lifespan of its batteries.
According to one of these reports, Tesla's current batteries, made up of 2170 cells, would lose around 5 % of their autonomy after 100,000 kilometres, a significant performance compared with the forecasts of some experts who estimated a loss of 30 % for the same distance. According to the American manufacturer's report, the degradation slows down after 300,000 km, reaching around 10 %. These promising figures indicate that owners of Tesla electric saloons and SUVs can expect to enjoy their vehicles for many years to come without suffering any significant loss of range.
According to data published by the manufacturer, the batteries in the Tesla Model Y, Model X and Model 3 retain on average 88% of their original capacity after 322,000 km travelled.
This means you can drive your Tesla hundreds of thousands of kilometres, while enjoying optimum performance.
Tailor-made guarantees for every model:
- Tesla Model Y and Model X: 8 years old or 240,000 km
- Tesla Model 3 Propulsion : 8 years old or 160,000 km
- Tesla Model 3 Great Autonomy and Performance : 8 years old or 192,000 km
Tesla offers four main models: the Model S, 3, X and Y. Each model and its variants have different cell capacities, which are important in determining the battery's daily range.
Below is a table detailing the differences in capacity between these models:
| Modèle | Capacité de la batterie (kWh) |
|---|---|
Tesla Model S (base model) | 100 |
Tesla Model S Plaid | 100 |
Tesla Model S Long Range | 100 |
Tesla Model 3 Standard Range Plus | 55 |
Tesla Model 3 Long Range | 75 |
Tesla Model 3 performance | 75 |
Tesla Model X (base model) | 100 |
Tesla Model X Plaid | 100 |
Tesla Model X Long Range | 100 |
Tesla Model Y Propulsion | 60 |
Tesla Model Y Long Range | 75 |
Tesla Model Y performance | 75 |
Tesla Model 3
The Tesla Model 3 is a compact saloon offering excellent value for money. It is available in three versions: Standard Range Plus, Long Range and Performance. It has a range of up to 600 km, and the Performance version accelerates from 0 to 100 km/h in just 3.1 seconds.
Tesla Model Y
The Tesla Model Y is a spacious and versatile compact SUV, ideal for families and outdoor activities. Available in Rear-wheel Drive and Long Range versions, it offers a range of up to 533 km.
If you're about to launch or expand your business, don't miss this exceptional opportunity: discover the Tesla Model Y utilitya real gem for your business needs.
Tesla Model S
The Tesla Model S is a top-of-the-range luxury saloon, renowned for its exceptional performance and refinement. Available in Long Range and Plaid versions, it offers a range of up to 663 km. The Plaid version is the world's fastest production car.
Tesla Model X
The Tesla Model X is a luxurious and spacious full-size SUV, available in Long Range and Plaid versions. It offers a range of up to 600 km and features Falcon Wings gullwing doors and a unique interior with a central "captain's seat".
On average, a Tesla should lose around 1 % of its charge per day when parked.
Here are a few concrete examples:
- Tesla Model 3 Standard Range Plus: With a 55 kWh battery and an average consumption of 250 Wh/km, it can travel around 354 km. If you drive 50 km a day, the battery should last around 7 days before needing to be recharged.
- Tesla Model Y Long Range: With a 75 kWh battery and an average consumption of 250 Wh/km, it can travel around 482 km. If you drive 80 km a day, the battery should last around 6 days before needing to be recharged.
How long does a Tesla battery last without driving?
When the Tesla is stationary, its battery undergoes a progressive discharge of its charge over time, a phenomenon commonly referred to as the "vampire drain".
This can lead to a loss of around 1 % of battery life per day, a figure that can increase with features such as Sentry Mode. However, Tesla implements regular software updates and battery management strategies to minimise this effect.
Can we expect a Tesla to last 20 years?
A Tesla is designed to last 20 years, provided it is meticulously maintained. Despite the inevitable degradation of the battery over time, it retains up to 80 % of its capacity after reaching 500,000 miles. This resilience demonstrates the commitment to long-term sustainability in the design of these vehicles.
Factors influencing battery life
Tesla battery life without driving is influenced by several key factors. Firstly, the Tesla model itself is a determining factor: the most recent versions tend to be fitted with more robust batteries, offering greater capacity. Secondly, the way you drive plays a major role: aggressive driving, with frequent acceleration and braking, can accelerate battery depletion compared with smoother driving.
In addition, climatic conditions are also important: extreme temperatures, hot or cold, can affect the durability of the battery. Finally, recharging practices have a significant impact: regular recharging to a low level or a complete discharge can reduce battery life.
