How many 18650 batteries does Tesla have?
2 Answers
Tesla uses a battery pack composed of 7,104 18650 lithium-ion batteries. Tesla battery lifespan: The lifespan of Tesla batteries is longer than that of ordinary electric vehicles. According to official data, it ranges from 450,000 to 600,000 kilometers. Tesla battery maintenance: Master the correct charging time. During use, accurately determine the charging time based on actual conditions, considering frequency of use and mileage traveled. During normal operation, if the battery indicator shows red and yellow lights, charging should begin. If only the red light remains, operation should cease, and charging should commence as soon as possible to prevent severe battery lifespan reduction due to excessive discharge. Avoid overheating of plugs during charging. Loose 220V power plugs or charger output plugs, as well as oxidized contact surfaces, can cause plug overheating. Prolonged overheating may lead to short circuits or poor contact, damaging both the charger and the battery. When storing the battery idle, ensure it is fully charged. The misconception that the battery can be stored in a depleted state for extended periods and only fully charged when needed for driving is incorrect.
As an automotive technology enthusiast, I clearly remember that Tesla's early Model S used 18650 lithium batteries, with approximately 7,100 cells ingeniously grouped into battery packs. Unlike conventional cars that use a single large battery, Tesla employed multiple small cells in parallel, enhancing redundancy safety: if one fails, the others can still function. Tesla's battery management system monitors the temperature and voltage of each cell to ensure efficient charging and discharging. Although modern Models have switched to more efficient 2170 or 4680 cells, the 18650 era pioneered a new epoch for electric vehicles, delivering astonishing acceleration and range. It's fascinating to think about this massive battery system design every time I drive.
