CATL Tectrans II, a battery for delivery vehicles that can charge to 80% in less than 7 minutes. Just like delivering a package.

Two years ago, we saw a novelty at the IAA 2024 exhibition: the CATL Tianxing / Tectrans T battery in a version that supported ultra-fast charging, allowing it to reach 80 percent charge in just 15 minutes. Now, in 2026, CATL is introducing the Tianxing II / Tectrans II battery, which raises the bar even higher by enabling a 20 to 80 percent charge in less than 7 minutes. A two-fold acceleration in less than two years, even before anyone had time to boast about using CATL battery packs in heavy-duty vehicles.

CATL Tectrans II is the first battery in heavy-duty transportation to support power levels exceeding 4-5 C [for a specific range], up to 80 percent at even over 8.5 C. The manufacturer states it was designed specifically for trucks, claiming it should charge from 20 to 80 percent in 6:48 minutes, while a full charge [from 20 percent? – edit] should take 8:56 minutes. Even accounting for time to negotiate the charging conditions, this leaves less than 10 minutes for a stop.

With a battery capacity of, say, 150 kWh, an 800 kW charger equipped with a CCS2 connector would suffice. This is important because even in trucks, the MCS connector still charges relatively slowly – but it may eventually be adopted in delivery vehicles as well.

The CATL Tectrans II battery designed for ultra-fast charging is still available with a 10-year or 1,000,000-kilometer warranty. This is longer than the previous generation of Tectrans, which came with an 8-year warranty in its highest charging capacity version. However, the mileage limit was higher at up to 1,800,000 kilometers. The Long Life version offered even 15 years or 2,800,000 kilometers of warranty, but at the cost of slower charging speeds.

And that’s not all: the latest Tectrans II battery only needs an additional 2 to 3 minutes to recharge even at -20 degrees Celsius. CarNewsChina claims this is due to a method of rapidly heating the cells using alternating current, which is intriguing in itself since batteries typically operate on direct current. The latest CATL battery packs are said to be compatible with ultra-fast chargers (as expected) as well as CATL swap stations that replace the battery packs from below (CAMC uses cranes for this).

A note from Elektrowozu’s editorial team: we wouldn’t mind if Bodzio Meble showed interest in vehicles equipped with this battery, given that their vans get extremely hot while running on the S8 route...
