Tesla uses Panasonic's NCR18650A battery, with a rated voltage of 3.6V and a capacity of 3.1Ah. Reasons why Tesla chooses Panasonic's 18650 battery: Higher energy density with better stability and consistency; effectively reduces the cost of the battery system; billions of 18650 batteries are produced globally each year, with continuously improving safety levels; small size but high controllability, reducing the impact of failures. Battery requirements: stable performance, high safety coefficient, and multiple recharge cycles. Tesla is an American electric vehicle and energy company founded by Martin Eberhard and Marc Tarpenning in Silicon Valley, California. It primarily manufactures and sells electric vehicles, solar panels, and energy storage equipment. Taking the Tesla Model 3 as an example, its body dimensions are 4694mm in length, 1850mm in width, and 1443mm in height, with a wheelbase of 2875mm. The Tesla Model 3 is a 4-door, 5-seat sedan equipped with a single-speed electric transmission. Tesla's main battery suppliers are two companies: LG and Panasonic.

How Wide is a Sedan Generally?

A sedan is generally about 1.8 meters wide and approximately 4.8 meters long. Precautions to take during the break-in period of a new car include: 1. Warm up before starting: Turn the key to the second position and wait for 5 to 10 seconds before starting to protect the new car's engine; 2. Avoid emergency braking: Emergency braking can impact the braking system during the break-in period, increasing the load on the chassis and engine; 3. Avoid overloading: Running a new car at full capacity during the break-in period can damage the components; 4.
