CATL, the world's largest battery maker, is taking its battery swapping strategy global—and Europe is the first stop. In a joint venture with Octopus Energy, the Chinese giant launched Swaptopus, the continent's first large-scale battery swapping network for electric trucks.
The move signals a major bet that swapping empty packs for full ones—rather than plugging in—will solve the trucking industry's biggest headache: downtime. Octopus and CATL aim to roll out stations across key European freight corridors, starting with pilot hubs in Germany and the UK.
Battery swapping is not new. Chinese EV maker NIO has built hundreds of swap stations for passenger cars, but CATL is applying the model to heavy-duty trucks, where charging times can exceed two hours. Swaptopus will swap a depleted battery in under five minutes. The joint venture also plans to integrate CATL's sodium-ion battery technology—a cheaper, more sustainable alternative to lithium-ion that does not rely on cobalt or nickel. Sodium-ion is still lower in energy density, but for trucking, where weight is less critical, it could unlock massive cost savings.
The announcement comes as European regulators push for faster electrification of commercial fleets. The EU's CO2 standards for heavy-duty vehicles, adopted in 2024, require a 45% reduction in emissions by 2030. Battery swapping could be a key enabler, especially for long-haul routes where charging infrastructure is sparse. Octopus Energy brings its expertise in renewable electricity and smart charging algorithms, while CATL contributes its manufacturing scale. Financial terms of the joint venture were not disclosed.
Industry analysts see the move as both a strategic offensive and a defensive hedge. By building infrastructure abroad, CATL reduces its dependence on the Chinese market, which accounts for 70% of its revenue. At the same time, sodium-ion batteries could lower the total cost of ownership for fleet operators, making electric trucks competitive with diesel sooner than expected. "This isn't just about swapping batteries—it's about reshaping the economics of trucking," said an analyst at Wood Mackenzie.
CATL's overseas battery swapping bet is a high-stakes play. Success depends on standardising battery packs across truck makers—a feat that has eluded the industry for years. CATL has already signed agreements with Volvo Trucks and Daimler Truck to adopt its swappable battery design. If the network scales, Swaptopus could become the standard for European e-truck charging. The first stations are expected to go live in early 2027. Sodium-ion production lines, meanwhile, are ramping up at CATL's plant in Ningde, with commercial shipments to European customers slated for late 2026. The race to electrify freight is accelerating—and swapping just became a serious contender.

Key Takeaways
- CATL and Octopus Energy formed Swaptopus, a joint venture to deploy Europe's first large-scale battery swapping network for electric trucks, targeting under five-minute swap times.
- The initial pilot hubs will be located in Germany and the UK, with plans to expand across major European freight corridors by 2027.
- CATL is integrating its sodium-ion battery technology into the Swaptopus network, offering a cobalt- and nickel-free alternative with lower costs but slightly reduced energy density.
- The European Union's 2024 CO2 standards for heavy-duty vehicles mandate a 45% emissions reduction by 2030, creating a regulatory tailwind for battery swapping infrastructure.
- CATL has secured agreements with Volvo Trucks and Daimler Truck to standardise swappable battery packs, a critical step for inter-operability and network adoption.
Frequently Asked Questions
CATL is investing in battery swapping networks for electric trucks, starting with Europe via its Swaptopus joint venture with Octopus Energy. The goal is to allow drivers to swap depleted batteries in under five minutes, reducing downtime compared to conventional charging.
Swaptopus will deploy modular battery swapping stations along European freight corridors. Electric trucks will drive into a station, and a robotic arm will replace the empty battery pack with a fully charged one. The process takes less than five minutes.
Sodium-ion batteries are cheaper and more sustainable than lithium-ion because they use abundant materials like sodium instead of cobalt and nickel. CATL plans to use them in its swapping network to reduce total cost of ownership for fleet operators.
Battery swapping drastically cuts charging time from hours to minutes, enabling higher fleet utilisation. It also reduces strain on the grid by centralising charging and allows battery ownership to be separated from vehicle ownership.
Pilot stations in Germany and the UK are expected to go live in early 2027. The companies plan to expand across Europe after that, contingent on regulatory approvals and truck-maker adoption.
CATL is the world's largest electric vehicle battery manufacturer, headquartered in Ningde, China. Octopus Energy is a UK-based energy company known for its renewable electricity supply and smart energy technology.
