What is the battery model used by Tesla?
3 Answers
Tesla uses the NCR18650 battery model, which is equipped with sensors to monitor the working status and temperature of each battery cell. The battery control system manages these parameters to prevent hazardous situations such as overheating, short circuits, or temperature discrepancies. Taking the 2021 Tesla Model S as an example, its body dimensions are: length 4975mm, width 1964mm, height 1445mm, with a wheelbase of 2960mm and a curb weight of 2069kg. The 2021 Tesla Model S is powered by a rear permanent magnet AC motor, delivering a maximum horsepower of 617PS, maximum power of 493kW, maximum torque of 755Nm, paired with a single-speed fixed gear ratio transmission.
Tesla uses a diverse range of battery models, with the current mainstay being the 2170 battery, employed in the Model 3 and Model Y. These batteries boast high energy density, making them ideal for long-distance travel without frequent charging. Personally, I find their newly introduced 4680 battery the most impressive—larger in size and packing more energy, reportedly offering extended range per charge and significantly faster charging speeds. Additionally, for the base models, Tesla utilizes Lithium Iron Phosphate (LFP) batteries, which are cost-effective and safer, making them perfect for daily commuting. As a car enthusiast, I always keep up with these updates. Tesla's 4680 battery is still in the rollout phase, but it's already being used in some newer versions of the Model Y. This battery optimizes structure to reduce vehicle weight, enhancing performance while being slightly more affordable. In the long run, the type of battery directly impacts a car's range and charging experience. Tesla continuously innovates in this area, so as regular consumers, we should pay close attention to this detail when purchasing a car—don’t just judge by appearances.
Having worked in the auto repair industry for a long time, I frequently encounter Tesla batteries. They primarily use the 2170 model, which boasts excellent energy density and powers the range of Models 3 and Y. The base models often use Lithium Iron Phosphate (LFP) batteries, which are more durable and cost-effective. In fact, early Model S/X vehicles used 18650 batteries, but these have largely been phased out now. The new 4680 batteries are being trialed in some Model Ys, featuring an integrated design that saves space and improves efficiency. As a mechanic, I remind everyone that different battery types require different maintenance approaches. For example, LFP batteries have a long lifespan but charge more slowly, and it's important to avoid deep discharges and conduct regular inspections to prevent potential issues. Replacing a battery isn't cheap, but Tesla continues to reduce costs through upgrades, with the 2180 battery gradually becoming more widespread.
