The idea of creating a European battery-swapping network for electric trucks is moving closer to implementation through Swaptopus, a collaboration between CATL and Octopus Energy focused on commercial transport trucks. The latest development came with CATL’s unveiling of the TECTRANS II battery at the IAA Transportation event, following the project’s initial announcement at Octopus Energy’s Energy Tech Summit in June.
The initiative aims to address two major obstacles to electrifying freight fleets: lengthy charging downtime and concerns related to battery life. Instead of relying on fully charging the vehicle each time, the battery-swapping model involves creating a network that allows a depleted battery to be replaced with a charged unit, potentially reducing downtime in long-distance transport operations.
What Does TECTRANS II Offer?
CATL says the system was designed as a universal, modular battery platform for commercial vehicles, with improvements aimed at fleet operating economics. Its gravimetric energy density is 170 watt-hours per kilogram, about 13% higher than the industry average according to the company, which could enable an additional payload of approximately 0.6 tons when using the same capacity.
In its highest configuration, the battery provides a range of up to 1,000 kilometers, with the ability to charge to 80% in 25 minutes using megawatt-level fast charging. It also uses a low-resistance design with full-length connecting tabs, which CATL says achieves a system round-trip efficiency of 96%, reducing charging losses and increasing the energy available for daily operations.
An Alliance That Goes Beyond Battery Manufacturing
CATL also signed a memorandum of understanding with DHL Group to accelerate the decarbonization of road transport in Europe. The collaboration includes other partners, including Xiaomi-backed Quibo Energy and FleetBoost, which provide mobile charging and energy storage systems, including the FleetBooster trailer integrated with CATL battery technologies.
CATL and Octopus say that, once completed, the network could support more than 300,000 electric trucks and unlock more than £30 billion in private investment, in addition to reducing Europe’s reliance on imported oil. However, these figures represent announced targets for the project and are not results achieved yet.
Why Does This Matter?
The initiative’s practical value does not depend solely on battery performance, but also on building an ecosystem that includes vehicles, charging and battery-swapping stations, storage, and life-cycle services. This integration could be important for freight fleets, which measure vehicles by uptime and payload, not just theoretical range. At the same time, the material does not specify when the network will begin operating, how many swapping stations there will be, or the model for standardizing batteries across companies—factors that will determine how scalable Swaptopus actually is.
For DHL, the collaboration falls within a stated goal of achieving net-zero emissions from logistics operations by 2050. For the market, the participation of transport, energy, and storage companies indicates that electrifying freight requires shared operational infrastructure, not merely a higher-density battery.
