Overview
- CATL publicly launched TECTRANS II at IAA Transportation in Hannover as a modular commercial-vehicle battery platform that can be configured for e-axle and central-drive trucks.
- In its heavy-duty configuration CATL claims up to 1,000 km of range, megawatt-class charging that reaches 80% state of charge in 25 minutes, a gravimetric energy density of about 170 Wh/kg, and roughly 96% round-trip efficiency.
- The company rates the heavy-duty pack for a 12-year, 1.5 million kilometre service life with 70% capacity retention and describes physical protections and BMS redundancy intended to boost durability and uptime.
- CATL signed a memorandum of understanding with DHL to pilot Green Freight Corridors in Europe and said the platform supports both charging and battery swapping to shorten OEM development cycles and cut R&D costs.
- Key implementation questions remain because CATL has not disclosed pack capacity, exact cell chemistry, or which megawatt charging protocol will be used, and wider deployment depends on charging/swapping infrastructure and OEM adoption.
