## Key takeaways

- CATL's 'electric-electric range extension' system pairs a 432 kWh or 513 kWh bottom-swap battery pack with a 77 kWh onboard range-extension pack; combined, the two configurations form 509 kWh and 590 kWh vehicle energy setups\.
- The plan's first signed batch covers 13,000 vehicles, involving companies including China Post, SF Express, Hunan Iron & Steel and Jianlong Group\.
- CATL plans to have 900 battery swap stations built cumulatively by the end of 2026 and 2,000 by 2027\.

## CATL launches Tianxing II and dual-battery range extension plan

CATL released its Tianxing II heavy truck full-scenario solution in Beijing on October 20, including a dual-battery system called 'electric-electric range extension\.' The plan went into production upon launch, and its first signed batch covers 13,000 vehicles, involving companies including China Post, SF Express, Hunan Iron & Steel and Jianlong Group\.

The electric-electric range extension system uses a 432 kWh or 513 kWh bottom-swap battery pack paired with a 77 kWh onboard range-extension pack\. The two batteries operate independently; when the main drive battery's charge is insufficient, the range-extension battery can continue supplying power\. Combined, the two batteries form vehicle energy configurations of 509 kWh and 590 kWh\.

The large-capacity main drive battery is leased, while the 77 kWh range-extension battery is held by the vehicle owner as an onboard asset\.

## Battery swap network and standardized swap blocks

CATL released two new standardized swap blocks, the 260\# and 300\#, with capacities of 432 kWh and 513 kWh respectively, adapted to vehicles with different wheelbases\. The Qiji 3\.0 battery swap station retains a 5-minute swap capability; CATL says the new station raises single-day service frequency by 28% and cuts station construction cost by 10%\.

Qiji battery swap has established five trunk routes, including Guangdong to Shanghai, Chengdu to Wuhan and Cangzhou to Yulin, with cumulative stable operating mileage across the network exceeding 5 million kilometers\. CATL plans to have 900 swap stations built cumulatively by the end of 2026 and 2,000 by 2027\.

In April 2025, when CATL released the Xiaoyao dual-core battery, it had already proposed the electric-electric range extension concept, using intelligent coordination between two independent energy zones to meet power demand in different scenarios\. In May 2025, CATL released the 75\# standardized swap block and announced the 'eight horizontal, ten vertical' national heavy truck battery swap network plan\.

## Rental and cost terms

CATL introduced billing by charging volume, with all recovered kinetic energy going to the user, and said the per-kWh rental cost for basic-package users can fall by up to 20%\. New vehicles can defer the start of their lease by up to 3 months, and leases can be stopped 2 months early during used-vehicle transactions\.

The first 3,000 electric-electric range extension vehicles can receive auto insurance rebates through specific partner channels, and the first 10,000 first owners can receive value-retention benefits of up to 15,000 yuan\.

Based on CATL's estimate assuming 400 kilometers of daily transport, the three-year total cost of ownership for an electric-electric range extension model is about 70,000 yuan lower than a battery-purchase model and more than 460,000 yuan lower than a diesel heavy truck\.

## Tianxing II variants and market figures

The Tianxing II bottom-mounted long-range version uses a 760 kWh battery with single-charge range exceeding 600 kilometers; paired with an 800V high-voltage platform, it is claimed to add 300 kilometers of range in 20 minutes, and it carries a 1\.5 million-kilometer warranty\.

The rear-mounted ultra-light version weighs about half a ton less than the industry average at the same energy capacity, freeing up more payload\. The rear-mounted ultra-thin version reduces battery thickness from 860mm to 580mm, and the bottom-mounted short-wheelbase version has a mass-production model with a 3\.35-meter wheelbase\.

In September, domestic new energy heavy truck sales were 33,100 units, up 37% year on year, with monthly penetration rising to 50\.28%\. In August, charging heavy trucks accounted for 80\.34% of pure electric heavy truck sales, up more than 10 percentage points from 69\.61% for full-year 2025\. As of this launch, more than 430,000 electric heavy trucks nationwide were equipped with CATL batteries\.
