What brand of battery does Tesla use?
3 Answers
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. To date, Tesla vehicles use 18650 lithium-ion batteries.
Tesla has multiple battery suppliers, and I have a relatively in-depth understanding of this. Primarily, Panasonic has been supplying battery cells for high-end models like the Model S and X, which offer strong range and durability. Currently, entry-level models such as the Model 3 and Y use batteries from LG Chem and CATL, with the latter specializing in lithium iron phosphate (LFP) technology, which is cost-effective but slightly weaker in winter performance. Tesla has independently developed the 4680 battery, used in the Cybertruck, which is said to improve energy density and charging efficiency. These changes are aimed at ensuring supply chain stability, such as collaborating with more Asian partners during global production expansion. The battery brand directly impacts electric vehicle performance, including acceleration feel and charging time. Therefore, I recommend checking specific configurations or consulting dealers when choosing a car, as there may be variations between different batches. Tesla's system optimization is excellent, balancing reliability and range.
As a Tesla owner, I paid special attention to the battery brand when choosing my car. My base Model 3 uses CATL batteries, and the actual range is quite good - a single charge gets me about 400 km, which is perfectly sufficient for daily commuting. Charging is convenient, with Superchargers restoring most of the battery in about half an hour. However, I've noticed my friend's car with Panasonic batteries performs better in winter. I've heard Tesla works with multiple suppliers, like LG providing batteries for certain models - all high-energy-density lithium-ion types. The battery warranty is long, typically 8 years or 160,000 km, which gives peace of mind for long-term use. I'd recommend researching supplier variations before buying, as differences between model years or regions might affect resale value and daily experience. Tesla's software updates for optimization are particularly useful in this regard.
