Does the domestically produced Tesla Y use 4680 batteries?

Previously, domestically produced Teslas used Panasonic batteries, but they have now switched to purchasing batteries from LG Chem for use in Model-3 cars produced at the Shanghai factory. Here is the relevant information: 1. LG Chem: LG Chem's battery market shipment ranking was fourth in the world in 2018. The first was CATL, which is also a Chinese company that has rapidly risen in recent years and has now partnered with the majority of automakers, even establishing factories overseas. 2. Development: LG Chem has established a joint venture with Geely Automobile Group to produce batteries for electric vehicles. This joint venture plans to secure an annual battery production capacity of 10 gigawatt-hours by the end of 2021.

Regarding the domestically produced Tesla Model Y, as far as I know, the current version manufactured in China does not use the 4680 battery. This new battery is Tesla's next-generation technology, which improves range and charging speed, but it is mainly being piloted at the Texas factory in North America. The Chinese version of the Tesla Model Y uses lithium iron phosphate (LFP) batteries provided by CATL, which is the mainstream choice due to its lower cost and higher safety, making it suitable for local market demand. The 4680 battery is still in the early stages of mass production, with limited deployment, and the domestic production line has not been adapted for it. Updates may be seen in the next year or two, but current owners of new vehicles report having LFP batteries. These batteries are also good, with stable range, though they are less high-tech and have slightly longer charging times. Switching batteries involves considering supply chain costs, and Tesla's China team has not announced any plans. It is recommended to ask the sales team more questions when purchasing a car or to keep an eye on official announcements for future upgrades.

Among domestic Tesla Model Y owners in my car enthusiast group, everyone has been discussing how the 4680 battery is a standout new feature that improves energy efficiency. However, the domestic version doesn't actually use it. The Model Y produced in Chinese factories primarily relies on CATL's 2170 or LFP battery packs, which are mature in technology and affordable. I checked out the new car introduction at the 4S store, and the salesperson also mentioned that only the new North American versions come with the 4680 battery—it hasn't been widely adopted here yet. The reasons might be the high difficulty in mass production or an unprepared supply chain. The advantage of the 4680 is that it reduces the risk of thermal runaway and theoretically extends battery life. If you're buying a Model Y in China, rest assured that the existing batteries perform well in real-world range, easily exceeding 400 kilometers. You can consider upgrading when the 4680 becomes more widely available in the future. But for now, it's a great deal—high value for money, so there's no need to chase the latest tech.

The domestic Tesla Model Y does not use the 4680 battery, as this new technology is currently only promoted in overseas factories such as Berlin. The Chinese version primarily relies on the lithium iron phosphate battery solution provided by CATL, which is economical, practical, fast-charging, and safe. The 4680 battery can save space and weight, but currently faces significant mass production challenges and has not been introduced in China. It is recommended to check official sources or inquire in owner groups for confirmation. Tesla's localized production considers cost factors while maintaining stable performance.
