What is the weight of a Tesla battery?
2 Answers
Tesla battery packs are placed in the chassis position between the front and rear axles, with a weight of up to 900 kilograms. This results in a lower center of gravity for the chassis, which greatly benefits the high-speed stability of the vehicle. The battery pack occupies almost the entire vehicle chassis, but it is not the main load-bearing component. The battery pack is protected by reinforcing ribs and a load-bearing frame, significantly reducing the risk of explosion in the event of a collision. Here is more detailed information: Tesla battery composition: The battery pack consists of 16 battery modules connected in series, and each module contains 444 lithium batteries, with every 74 batteries connected in parallel. Therefore, the Tesla Model S battery pack is composed of 7,104 18650 lithium batteries. Current introduction: The main fuse is located at the front end of the battery pack and is protected by a casing to prevent impact. It uses the German Bussmann fuse, with a rated operating current of 630A, a rated voltage of 690V, and a breaking current of 700-200kA.
When I first bought a Tesla, I was also curious about the battery weight. I remember the Model S battery pack was particularly heavy, weighing around 600 kilograms—almost a third of the car's total weight. When I changed tires myself, the mechanic complained about how strenuous it was to lift. This weight not only affects suspension stiffness but also makes cornering slightly more stable. In daily driving, a heavier battery means longer range, but you can clearly feel the body response lag a bit when stepping on the accelerator. There’s quite a difference between Tesla models—for example, the standard Model 3 battery is lighter, probably around 480 kg, more energy-efficient but requiring more frequent charging. Over time, I’ve found that regular maintenance can mitigate aging-related weight gain. I’d advise new owners to choose based on practicality rather than just specs. Weight is like life—a bit heavy but carrying the future.
