China’s electric trucking industry has taken a major step toward faster, more flexible freight transportation. Battery giant CATL has introduced a dual-electric range extension system that pairs a swappable traction battery with a permanent onboard reserve, potentially reducing costly downtime and wasted battery capacity. Announced in Beijing on October 20, 2026, CATL and QIJI Energy are combining the technology with an upgraded battery-swapping network and new leasing options for logistics operators. With commercial agreements covering 13,000 heavy-duty trucks, the launch signals growing interest in alternatives to diesel freight. But can two all-electric batteries finally address truck range anxiety at scale?
What Has CATL Launched?
The new Tectrans II dual-electric solution combines a 432 kWh or 513 kWh swappable battery with a fixed 77 kWh backup. The reserve enables deeper use of the main pack, while QIJI stations aim to replace batteries in approximately five minutes.
How the 1+X Dual-Battery System Works
Unlike conventional range extenders powered by diesel or petrol generators, this design remains fully electric. Its two independent batteries serve different purposes:
- Main battery (1): A chassis-mounted, standardized 260# pack rated at 432 kWh or 300# pack rated at 513 kWh, exchanged at compatible swap stations.
- Reserve battery (X): A permanently installed 77 kWh unit behind the driver’s cab, supporting 3C charging and supplying electricity when the main pack runs low.
Depending on the swappable pack selected, combined nominal capacity reaches 509 kWh or 590 kWh. CATL says operators can upgrade the two systems independently, adapting the reserve battery for cold climates, high power or greater energy density. The company has not specified its cell chemistry or published a verified driving range for this configuration.
Why 95% Battery Utilization Matters
A familiar problem for battery-swapping fleets is returning too early. Drivers may arrive with roughly 30% charge remaining, worried about reaching another station. That means valuable leased energy goes unused.
With the onboard reserve, CATL says the main pack’s depth of discharge can rise from approximately 70% to more than 95%. When its state of charge falls below 5%, power can transfer to the backup within milliseconds without interrupting driving. This improves usable capacity per swap, although actual range will still depend on cargo weight, terrain, weather and driving conditions.
Five-Minute Swaps and Lower Fleet Costs
CATL and QIJI Energy are also changing how heavy-duty EV operators access batteries. QIJI claims its automated stations complete swaps in around five minutes, with a 99.99% first-time success rate. Newer stations reportedly require no excavation pits, can be deployed in five days and reduce construction costs by 10%.
Under the Battery-as-a-Service model, fleets can retain ownership of the 77 kWh reserve while leasing larger chassis batteries according to seasonal freight demand. Customers are billed for net energy charged, rather than gross energy discharged, preserving the benefit of regenerative braking. CATL says basic-plan per-kWh rental fees could fall by up to 20%; real savings will vary by route, usage and contract.
13,000 Trucks and Ambitious Swapping Targets
At the Beijing launch, agreements covering 13,000 vehicles were announced with logistics-sector partners. Those agreements indicate commercial interest but should not be confused with 13,000 delivered trucks.
QIJI’s planned rollout includes:
- 900 stations: Heavy-truck swap stations targeted by the end of 2026.
- 2,000 stations: Targeted for 2027.
- 10,000 stations: Nationwide longer-term ambition with partners.
CATL also presented ultra-light, ultra-thin, short-haul and long-range Tectrans II battery solutions. Separately, its Swaptopus joint venture with Octopus Energy is pursuing European truck-swapping hubs, including prospective UK sites in 2027.
CATL and QIJI Energy also say their broader ecosystem will connect truckmakers, insurers, financiers and reliable service partners. That support matters because fleets evaluate electric vehicles on resale value, predictable maintenance and uptime, not battery specifications alone.
What This Means for Electric Freight
China’s new-energy heavy-truck market share reportedly reached 50.28% in September 2026, highlighting rapid adoption. However, network coverage, truck compatibility, battery economics and dependable servicing remain essential. For Indian and global fleet operators, the important development is not simply a bigger battery: CATL and QIJI Energy are proposing a more flexible way to buy, use and replenish electricity. Whether the model transforms long-distance trucking will depend on station rollout and proven costs in daily operations.
