CATL and Octopus Launch European Battery Swap Network for Trucks

CATL and Octopus Energy have formalized a joint venture named Swaptopus to build a battery swapping infrastructure for commercial freight vehicles in Europe. The initiative seeks to address the primary obstacles to electrifying heavy logistics, specifically the lengthy charging times and the rapid degradation of large battery packs that currently deter fleet operators.

This partnership was advanced following the reveal of the TECTRANS II, a next-generation battery module designed to function as a universal platform for electric trucks. By allowing drivers to swap depleted batteries for charged ones rather than waiting for a full recharge, the system promises to significantly reduce vehicle downtime on long-haul routes, according to reporting from GN auto tech/ev.

Technical Improvements in Energy Density

The new battery system features a gravimetric energy density of 170 Wh/kg, which is approximately 13 percent higher than the current industry average. For fleet operators, this translates into tangible economic benefits: the increased efficiency allows trucks to carry an additional 0.6 tonnes of cargo without increasing the weight of the power source.

The module also introduces a full-tab low-impedance design that achieves a 96 percent round-trip efficiency. This reduces energy lost during the charging and discharging cycles, ensuring that more of the purchased electricity is actually used to move the vehicle, thereby lowering operational costs per kilometer.

Industry Coalition for Zero Emissions

The expansion of this network relies on a broad coalition of partners. CATL has signed a memorandum of understanding with DHL Group to accelerate the adoption of these electric trucks. The ecosystem also includes Quibo Energy and FleetBoost, which provide mobile charging solutions and battery storage systems to support the logistics chain.

DHL views this collaboration as a critical step toward its goal of achieving net-zero logistics emissions by 2050. By integrating real-world logistics demands with vehicle hardware and energy storage, the partners aim to create a scalable solution that reduces Europe's reliance on imported fossil fuels.

Economic Scale and Investment Goals

CATL and Octopus project that the Swaptopus network could eventually support over 300,000 electric trucks. They estimate this infrastructure could unlock more than 30 billion pounds in private investment. The long-term goal is to shift the freight sector from diesel dependence to sustainably produced electricity, creating jobs while stabilizing fuel costs for carriers.
