CATL has introduced the QIJI battery swapping system, a technology designed for large electric trucks to minimize downtime by allowing a full battery replacement in approximately five minutes. The system incorporates a 77kWh secondary reserve battery, which enables vehicles to operate even when the main battery drops below 5% capacity. CATL intends to expand its infrastructure significantly, targeting 900 swapping stations in China by the end of 2026 and a long-term goal of 10,000 stations. Building on this technology, CATL and Peterbilt have introduced a dual-electric range extension system using a “1+X” architecture. This setup combines a standardized, swappable battery pack from the QIJI Energy network with a secondary range-extension battery. This configuration allows fleets to lease main batteries seasonally to manage costs while maintaining the range-extension battery for the vehicle's service life. In the United States, Peterbilt has also extended a cooperative purchasing agreement through July 2028 to provide public agencies with streamlined access to its medium- and heavy-duty battery electric truck lineup. Recent technical details regarding the QIJI ecosystem reveal a dual-battery architecture utilizing large, swappable primary batteries with capacities of either 432 kWh or 513 kWh. These are paired with the onboard 77 kWh range-extender battery to reduce downtime and financial barriers for freight operators.
