## Tianxing II Product Lineup

CATL introduced four Tianxing II heavy-truck battery versions: the rear-mounted Ultra-Light, rear-mounted Ultra-Thin, underfloor short-wheelbase and underfloor long-range models, alongside the Electric-Electric Range-Extender version\. The products use third-generation CTP integrated cell-to-pack technology and integrated die-casting\.

The rear-mounted Ultra-Light version weighs 530\+ kg less than the industry average, uses cells with 450Wh/L volumetric energy density and is cited at about 12,000 yuan in additional annual revenue per truck\. The rear-mounted Ultra-Thin version reduces battery thickness by 280mm, extends cargo-box length to 8\.8m, adds 3m³ of extra load capacity and is cited at 25,000 yuan more earnings per vehicle per year\.

The underfloor short-wheelbase version shortens wheelbase by 0\.45m from the roughly 3\.8m common in the industry, carries 3m³ more cargo, reduces turning radius by 0\.9m, raises the longitudinal passing angle by 3° and lowers center-of-gravity height to 0\.85m; CATL cites more than 50,000 yuan in added annual revenue per vehicle\. The underfloor long-range version offers 760kWh and a single-charge range of more than 600km, with 20 minutes of charging adding 300km\.

## Electric-Electric Range-Extender and Swap Blocks

The Tianxing II Electric-Electric Range-Extender version combines an underfloor main-drive battery system of 432kWh or 513kWh with a 77kWh rear-mounted range-extender battery\. The main-drive battery can be run down to 5% state of charge before the truck returns to a swap station\.

CATL introduced two standardized swap blocks: 260\# at 432kWh for models with a 3\.8m wheelbase and 300\# at 513kWh for models with a 4\.2m wheelbase\.

## Qiji Swap Station 3\.0 and Network Plans

The Qiji Swap Station 3\.0 raises single-day service frequency by 28%, cuts overall station construction cost by 10% and, with its pit-free design, can be installed in as little as five days\.

CATL plans to build 900 Qiji swap stations by the end of 2026, forming a 1\.5-hour trunk-line charging circle, and 2,000 stations in 2027 to cover the national highway backbone\. The long-term target for the Qiji network is 10,000 stations\.

## Battery Rental and Owner Benefits

CATL's battery rental plan bills by charged electricity volume, with energy recovered through regenerative braking during driving credited entirely to the user\. Electric-Electric Range-Extender customers can choose flexible, on-demand rental starting from one year, delay the start of rental by up to three months on a new vehicle and pause rental up to two months ahead during a used-vehicle transaction; further rental-pause benefits are to be introduced\.

The first 3,000 Electric-Electric Range-Extender owners receive a subsidy of 12,000 yuan per vehicle\. The first 1,000 Qiji battery partners can obtain a zero-cost supply-chain finance solution, and the first 10,000 first owners are eligible for a maximum value-retention benefit of 15,000 yuan per vehicle\.
