Submission + - CATL launches 170 Wh/kg modular, heavy-duty vehicle battery w/621 mile range (interestingengineering.com)
fahrbot-bot writes: Interesting Engineering is reporting that the Chinese battery company CATL has unveiled its next-generation modular commercial vehicle battery platform, TECTRANS II, at IAA Transportation 2026 in Hanover.
Rather than a basic cell update, the system is a adaptable modular architecture that integrates into existing vehicle lines. Truck manufacturers can achieve up to 1,000 kilometers (621 miles) of range on a single charge, backed by megawatt-level fast charging that replenishes 80% capacity in 25 minutes.
The battery delivers a gravimetric energy density of 170 Wh/kg, exceeding the industry average by 13% and increasing payload capacity by 0.6 tonnes.
CATL rates the heavy-duty truck setup for a 12-year, 1.5-million-kilometer (932,056 mile) operating lifecycle while retaining 70 percent capacity.
