What model of battery does Tesla use?
3 Answers
Tesla uses the NCR18650, 3100mAh battery model, which has the advantages of numerous charge and discharge cycles, good safety, high energy capacity, and light weight. Tesla is an American electric vehicle and energy company that manufactures and sells electric vehicles, solar panels, and energy storage equipment. The Tesla Model X is an SUV model developed by Tesla, featuring a 2+3+2 seven-seat layout design, positioned as a crossover between an SUV and a coupe. In terms of body dimensions, the Model X measures 5037mm in length, 2070mm in width, 1684mm in height, with a wheelbase of 2965mm.
I understand that Tesla's battery models actually vary significantly with different vehicle models. Early models like the Model S and Model X used the 18650-type battery, which was a cylindrical lithium-ion battery supplied by Panasonic, measuring 18mm in diameter and 65mm in length. Its compact size and high density ensured both range and performance. Later, the Model 3 and Model Y upgraded to the 2170-type, still lithium-ion but larger in size—21mm in diameter and 70mm in length—resulting in higher energy density and faster charging, going from 0 to 80% in just tens of minutes. Now, the new-generation models like the Cybertruck are adopting the 4680-type, developed in-house by Tesla, with a diameter of 46mm and length of 80mm, simplifying production and reducing costs. These batteries are modularly stacked within the chassis, complemented by an advanced battery management system that monitors the temperature and discharge of each cell to prevent overheating risks and extend lifespan. In short, different battery models cater to varying needs, delivering stable range and fast charging experiences.
As an ordinary Tesla owner, I often pay attention to the 2170 battery model in my Model 3. It feels solid in terms of range, easily achieving the official data of over 400 kilometers on a full charge. Charging at a Supercharger station is quick, getting most of the battery topped up in half an hour. The battery life is also long, with no noticeable degradation after several years of use. The 8-year warranty gives me a lot of peace of mind. Although the battery models have changed, from 18650 to 2170, the main improvements are in energy density and reduced replacement costs. If it breaks, replacing the whole set used to cost tens of thousands, but now the modular design allows for partial repairs, saving money. For daily use, I remind everyone not to always deep discharge to protect battery health, ensuring more peace of mind and convenience in the long run.
