Does Tesla use Chinese batteries?
Tesla utilizes Chinese batteries in specific production lines, notably for its China-made vehicles and energy storage projects. Contemporary Amperex Technology Co. Limited (CATL), a leading Chinese battery manufacturer, supplies lithium iron phosphate (LFP) cells for Tesla’s Shanghai-produced Model Y and energy storage systems like Megapack. This partnership underscores Tesla’s localization strategy to optimize costs and meet regional demand.

Which Chinese companies supply batteries to Tesla?
CATL and Eve Energy are primary suppliers, with CATL providing LFP batteries for vehicles and energy storage systems. Eve Energy contributes to Tesla’s stationary storage projects. Beyond these, Gotion High-Tech and BYD have also engaged in preliminary discussions for future collaborations.
Tesla’s collaboration with CATL began in 2021, focusing on cost-effective LFP chemistry for entry-level models. The 72V LFP battery packs used in Model Y Standard Range offer 60 kWh capacity, balancing energy density and thermal safety. Pro Tip: LFP batteries maintain >80% capacity after 3,000 cycles, ideal for high-utilization EVs. For example, a Shanghai-made Model Y with CATL’s pack achieves 525 km CLTC range, 12% cheaper than nickel-cobalt-aluminum (NCA) equivalents. However, cold-weather performance remains a trade-off—charging speeds drop 35% below -10°C.
Are Tesla’s global models using Chinese batteries?
Only China-made vehicles and energy storage products currently integrate Chinese batteries. Fremont and Berlin factories still rely on Panasonic (NCA) and LG Energy Solution (NCM) cells. This regional differentiation aligns with Tesla’s supply chain diversification strategy.
| Region | Battery Supplier | Chemistry |
|---|---|---|
| China | CATL | LFP |
| USA | Panasonic | NCA |
| Europe | LGES | NCM |
CATL’s LFP cells dominate Tesla’s Shanghai output, covering 70% of Q1 2025 production. Transitionally, Berlin’s Model Y Performance still uses LG’s NCM811 for higher discharge rates. Pro Tip: Cross-region battery swaps void warranties—always use region-specific packs. For instance, attempting to install a CATL LFP pack in a U.S. Model 3 triggers BMS compatibility errors due to differing voltage curves.

FAQs
No—CATL’s LFP cells meet Tesla’s Global Quality Protocol (GQP), undergoing 23 safety tests including nail penetration and overcharge. Cycle life exceeds 4,000 charges at 1C rate.
Can Chinese Tesla batteries be exported?
Only for energy storage systems—vehicle batteries face export restrictions due to LFP’s UN38.3 certification variances. Megapack exports from Shanghai to Australia use CATL cells with modified venting mechanisms.
