What brand of battery does Tesla use?
2 Answers
Tesla uses Panasonic batteries, with the model number NCR18650A, a rated voltage of 3.6V, and a capacity of 3.1AH. Batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. Taking the 2021 Tesla MODEL3 as an example, its body dimensions are: length 4694 mm, width 1850 mm, height 1443 mm, with a wheelbase of 2875 mm. The 2021 Tesla MODEL3 has a maximum power of 202 kW and a maximum torque of 404 Nm, paired with an electric vehicle single-speed transmission.
Tesla's battery sources have become quite diversified, no longer solely relying on Panasonic as in the past. Early Model S vehicles used Panasonic-supplied 1865 cylindrical batteries, reflecting a long-standing partnership. Later, when Model 3 entered mass production, LG Chem was added as a supplier, particularly for the European and Asian markets. In China, Tesla opted for CATL's lithium iron phosphate (LFP) batteries—safe, economical, and well-suited to local consumer needs. Now, Tesla has developed its own 4680 large-cylindrical batteries, produced at its Berlin and Texas factories, aiming to reduce costs and extend range through in-house R&D. I think this diversified supplier strategy is smart, mitigating supply chain risks while allowing the selection of the most suitable battery type for each vehicle's performance. If you buy a new Model Y in North America, it might come with Panasonic or Tesla's in-house 4680 batteries, ensuring balanced stability and performance.
