Does the Domestic Tesla Y Use 4680 Batteries?

Domestic Tesla Y uses 4680 batteries. Criteria for battery scrapping: When the discharge capacity of the battery falls below approximately 60% of its rated capacity, and functionality cannot be restored after repair, it should be scrapped. If severe heating occurs during charging along with deformation of the battery casing, it also needs to be scrapped. Methods for daily battery maintenance: Before turning off the vehicle, ensure all electrical devices are shut down. Avoid long-term parking of the vehicle; restart the vehicle every week to maintain optimal battery voltage. Functions of car batteries: Car batteries are primarily used for starting and lighting in automobiles, motorcycles, tractors, diesel engines, etc. They act as voltage stabilizers for the vehicle's electrical system, mitigating impact voltages and protecting electronic equipment in the car. Working principle of batteries: The working principle involves converting chemical energy into electrical energy. The battery uses lead plates filled with sponge-like lead as the negative electrode, lead plates filled with lead dioxide as the positive electrode, and 22-28% dilute sulfuric acid as the electrolyte. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted back into electrical energy. When discharging, metallic lead at the negative electrode undergoes oxidation, turning into lead sulfate, while lead dioxide at the positive electrode undergoes reduction, also turning into lead sulfate.

I've been driving the Model Y for several months now. The domestic version indeed doesn't use the 4680 battery; it's equipped with 2170 lithium-ion cells supplied by local partners like CATL. Tesla's 4680 represents next-generation technology currently being mass-produced only at the Texas factory in the US, offering improved range and charging speed. However, Chinese production lines haven't adopted this yet, still relying on the older technology. As an owner, I find the daily range satisfactory - officially rated at 500km, though slightly less with AC on, but it charges rapidly at stations. Friends mention potential factory upgrades, but this year's new vehicles maintain this battery configuration. It's reliable and worry-free. If you're not in urgent need, waiting for 4680-equipped models might be wiser since battery generation directly impacts vehicle performance.

Having followed electric vehicle technology for a while, I must say the domestically produced Tesla Model Y doesn't use the 4680 battery—it's equipped with the 2170 cylindrical cells. The 4680 is Tesla's large-format cylindrical design, measuring 46x80mm, which reduces parts count, increases energy density, and achieves longer range with faster charging. It's already being used in the U.S. Model Y. However, in China, due to supply chain considerations and production cost control, CATL's 2170 batteries remain mainstream, offering stable performance albeit with older technology. From my personal testing, the domestic Model Y delivers over 400 km of real-world range and charges to 80% in half an hour, but the 4680 could truly push these limits. Looking ahead, upgrades are planned for the Shanghai factory, as rapid battery tech iteration is the trend.

From a market perspective, the domestically produced Tesla Model Y currently does not come equipped with 4680 batteries. The Shanghai factory uses the 2170 battery solution during production. Tesla's strategy involves a global distribution of new products: 4680 technology is prioritized in Texas, while the China factory maintains the 2170 configuration due to local partnerships and supply chain stability. Industry data shows that 4680 can reduce costs and improve performance, but domestic competition is fierce, with alternatives like BYD's Blade Battery posing challenges. I believe a future transition is possible, but for now, consumers receive a Model Y with reliable batteries that are more affordable, delivering solid overall performance.
