CATL unveils dual-battery system for electric heavy-duty trucks
CATL has introduced a new dual-battery architecture designed to accelerate the adoption of electric heavy-duty trucks by addressing range anxiety and operational costs. The system, referred to as a “1+X” architecture, combines a large, standardized, chassis-mounted swappable battery with a smaller, fixed range-extension battery located behind the cab.
This configuration allows for a higher depth of discharge. While conventional battery-swapping operations often see drivers returning batteries with significant unused capacity, CATL’s system enables the main battery to be used until it reaches a state of charge below 5%. At this threshold, power is transferred to the 77kWh backup battery within milliseconds, ensuring continuous operation.
The company is also expanding its QIJI battery-swapping infrastructure. CATL aims to reach 900 heavy-truck swapping stations by the end of 2026, with a target of 2,000 stations by 2027 and a long-term goal of 10,000. Additionally, CATL has entered a strategic partnership with Huawei-backed Yinwang to coordinate automated battery swapping through cloud-connected vehicle systems.
