[Tesla Semi Electric Truck Battery Capacity Officially Revealed, Up to 822 kWh] The California Air Resources Board recently confirmed the battery capacity of the Tesla Semi electric truck through regulatory filings, with actual specifications lower than the figures Musk initially disclosed in 2022. According to the documents, the long-range Tesla Semi is equipped with an 822 kWh battery pack, while the standard-range version has 548 kWh. Both car models use Tesla 4680 battery cells with NCMA lithium-ion chemistry.

KNS announced on March 25 that its affiliate ZR Korea has begun mass shipments of key components for 4680 cylindrical batteries to a major North American electric vehicle manufacturer, marking the first such case in Korea. The products are used in the riveting process of 4680 batteries and serve as critical components that determine battery safety and structural stability. They function to bond and seal multiple insulating parts, including insulators and gaskets.

According to Teslamac on Feb. 25 (local time), select rear-wheel-drive (RWD) Model Y vehicles produced at Tesla’s Grünheide plant in Germany have been equipped with U.S.-made 4680 battery cells since January this year. The 4680-format batteries are produced at Tesla’s Gigafactory Texas in the United States.

With the release of the half-year data for power batteries, the situation has become even clearer.
