Tesla’s Battery Sourcing and Manufacturing

Tesla is at the frontline of the electric car revolution, and advanced battery technology is critical to its success. While Tesla sources its batteries from the same suppliers as other EV manufacturers, such as Panasonic, LG Chem, CATL, Ganfeng Lithium, BHP, Glencore, Liontown Resources, Piedmont, and BYD, it has significantly improved battery design and advanced thermal management system that includes liquid glycol coolant circulated throughout the battery pack to maintain optimal operating temperatures to keep the vehicle running efficiently. This liquid glycol coolant system provides a liquid cooling behavior in the battery that helps protect the batteries from damage during frequent fast-charging sessions. If you are doing Frequent supercharging, it may not harm the batteries, but extraordinarily high or low temperatures during fast charging sessions can still negatively impact battery life. So, it’s best to avoid Supercharging in very hot or cold conditions.

Tesla’s Latest Battery Technologies and Innovations

Tesla’s batteries are based on lithium-ion chemistry, similar to most other electric vehicle manufacturers. Tesla’s battery management carefully controls charging and discharging to avoid stress on the battery, even with frequent DC fast charging. It will help keep your battery healthy for a long time. However, one of its main innovations is using cylindrical cells, which allow for better thermal management and more energy than the prismatic cells or pouches used by many other automakers. According to the CATL, a major battery manufacturer, the cost of the cylindrical cells is expected to come down by $60 per kWh by mid-2024. Even Goldman Sachs Research expects the battery prices to fall to $99 per kWh of storage capacity by 2025, a 40% decrease from 2023 prices. Tesla’s battery and thermal management are considered good, and its proven performance record allows it to continue developing and improving its cars in the field. Their massive battery packs in the Gigafactory manufacturing plant give an extra boost.

Jeff Dahn Said that…

“Tesla has really revolutionized that part of the battery pack and made it much more sophisticated, and it gives them the competitive advantage,”

In addition to its battery design, Tesla builds most of its electrical systems, and its inverters have been more efficient than others. This vertical integration gives Tesla greater control over the entire process, from raw materials to final assembly. It allows them to optimize each step for maximum efficiency and cost savings.

Tesla has also invested heavily in battery research and development, with a dedicated team of scientists and engineers working to improve energy density, longevity, and cost. This allows them to continue increasing the volume of their cars as prices rise. Tesla is working on new battery technologies, such as 4680 cells and high-nickel chemistries. These advancements in high technology may improve the battery’s performance and longevity and be cost-effective. The Tesla Model S has set a high standard with its impressive performance, offering a range of 405 miles on a single charge. Meanwhile, the new Model 3 has marked significant advancements across various features, demonstrating Tesla’s consistent ability to deliver excellent outcomes.

Tesla Battery Lifespan, Degradation, and Warranty

When you are thinking about buying an Electric Vehicle, the first thing that comes to mind is the battery life of EVs and how long the Tesla EV car lasts. Tesla battery packs are designed to last a long lifespan with minimal degradation. Many owners report less than 10% capacity loss even after 150,000-200,000 miles. Tesla now warrants batteries to maintain 70% capacity for eight years or 100,000-150,000 miles.

Comparing Tesla’s Battery Technology to Competitors

As we have seen, the electric vehicles (EVs) market has emerged constantly, so the main question is the battery technology, which is the crucial factor among automakers. Tesla, one of the pioneers of the electric car industry, has long been known for its battery innovations. However, Tesla is not the only player in the game. Other automakers such as General Motors, Volkswagen, and BYD have also invested heavily in battery technology. GM’s Ultium battery has a specially designed pouch for easy packaging and high power. At the same time, Chinese manufacturer BYD has developed its own “wearable battery” with improved safety. Even though Tesla has the best technology, it can’t rest on their current achievements; they are constantly trying to develop or find new technology. If a new, better battery technology emerges, Tesla will likely acquire it quickly to gain a competitive advantage. In 2024, Tesla is set to launch its upcoming car, the “Tesla Roadster,” which is expected to feature the latest battery innovations and technology, pushing the boundaries of EV performance.
