How to Identify the Brand of Tesla Batteries?
3 Answers
Tesla battery brand identification method: The Tesla battery pack has an identity plate that indicates its brand. The batteries used by Tesla are very similar to the AA batteries commonly seen in daily life, but these batteries are called 18650 lithium-ion batteries. The Tesla Model Y is a compact SUV with dimensions of 4750mm in length, 1921mm in width, and 1624mm in height, with a wheelbase of 2890mm. It features a combination of double-wishbone independent front suspension and multi-link independent rear suspension. The Tesla Model Y is powered purely by electricity and uses a single-speed transmission typical of electric vehicles.
After driving a Tesla for several years, I find it quite interesting to check the battery brand. Tesla uses batteries from different suppliers, such as Panasonic and CATL. To find out which one is in your car, first look for vehicle details in your purchase order or the Tesla App. Enter the last few digits of the Vehicle Identification Number (VIN), and some online tools can decode it—for example, the 7th digit of the VIN often represents the supplier code. Panasonic batteries are usually marked with E or F, while CATL might use other codes. Alternatively, you can ask the salesperson at delivery or inquire at a service center for reliable information. There’s not much difference between battery brands in daily use, though Panasonic might have a slight edge in range, such as less winter degradation. It’s advisable for owners to keep a record of their battery brand details for future maintenance or resale purposes.
As an average car owner, I was curious about how to check the battery brand when purchasing a Tesla. Actually, the supplier information is listed in the order configuration sheet or user manual; if not, try looking for battery details in the vehicle settings page of your Tesla account. My Model Y has a Panasonic battery, while my friend's has a CATL one, with no visible external differences. Knowing the brand is mainly out of interest—for example, Panasonic batteries are said to be more durable, while CATL offers more economical options. It usually doesn't make much difference in daily use, but it's advisable to stay updated on vehicle updates, as Tesla sometimes changes suppliers. Don't attempt to disassemble the car if you're not knowledgeable—the battery is deeply integrated and not visible at a glance. Contacting support is a more reliable and safer approach.
