Joint Venture Targets Europe’s Heavy-Truck Market, UK to Launch First Hubs in 2027
The world’s largest power battery manufacturer, CATL, and UK energy technology company Octopus Energy have formed a joint venture, Swaptopus, which plans to activate its first automated battery-swapping hubs in the UK by 2027. The venture aims to establish over 30 swapping hubs across Europe by 2035. Swaptopus claims its network could eventually support more than 300,000 heavy electric trucks and attract over £30 billion in private investment. This deployment not only challenges Europe’s existing charging infrastructure but may also redefine the commercial models linking trucks, batteries, energy systems, and operators.
CATL held a 39.2% share of the global power battery market in 2025, leading the industry. Octopus Energy, meanwhile, manages customers and flexible energy assets through its Kraken software platform. The partnership combines battery technology with energy management expertise. Swaptopus’s swapping hubs will utilize CATL’s Qiji heavy-truck battery-swapping platform, which has been validated in China. The platform integrates standardized battery modules, automated swapping equipment, and a cloud-based control system, enabling battery replacements in just minutes.
China’s Experience Transplanted to Europe, Qiji Platform as the Technological Foundation
The Qiji platform serves as the core technology for Swaptopus. By the end of 2025, CATL had built 305 commercial or heavy-truck swapping stations in China, with a target of 900 stations in 2026 and plans to cover a 150,000-kilometer freight network by 2030. The Qiji platform currently supports over 30 chassis-swapping models from more than ten truck manufacturers, demonstrating its technical architecture’s industry-wide synergy.
CATL’s heavy-truck battery module, the 75# block, has not been publicly disclosed, but Octopus Energy has indicated that a single swap provides approximately 500 kWh of capacity. External estimates suggest it may consist of three 171 kWh modules. The Qiji platform’s standardized design aims to establish battery modules as a common standard for truck chassis, swapping stations, and operational software, lowering compatibility barriers for vehicles and infrastructure.
However, the commercial viability of the Qiji platform remains unproven. Key metrics—such as station utilization rates, battery inventory management, grid load, maintenance costs, and residual value assessments—have not been publicly disclosed at scale. Additionally, the economic feasibility of the swapping model heavily depends on station utilization. High-frequency use could spread costs but may exacerbate grid strain, while low-frequency use could lead to battery idling, impacting return on investment.
Policy Support and Infrastructure Advantages: Can China’s Model Be Replicated?
China’s policy support provides a favorable environment for the Qiji platform. According to China’s 2030 implementation plan, new-energy heavy trucks must account for 40% of sales, with a total fleet exceeding 1.6 million vehicles. The plan also calls for 3,000 heavy-truck charging and swapping stations and 30,000 kilometers of zero-carbon freight corridors. The policy not only sets sales targets but also integrates vehicles, corridors, stations, and the grid into a comprehensive energy infrastructure system.
While Sinopec is not directly involved in Swaptopus, its role in China highlights the importance of infrastructure integration. Sinopec operates over 30,000 gas stations and is gradually adding charging and swapping facilities. It has a strategic cooperation agreement with CATL covering energy storage, passenger vehicles, and commercial vehicle swapping. In China, Sinopec provides site locations and operational experience, while in Europe, Octopus Energy fills the energy management gap with its expertise in power procurement, flexible dispatch, and software capabilities.
Advantages and Challenges of Battery-Swapping: Europe Faces Multiple Tests
Compared to traditional charging, the primary advantage of battery-swapping is reduced vehicle downtime. By shifting charging demand to battery inventory, heavy trucks can complete battery replacements in minutes, avoiding lengthy charging waits. Additionally, separating battery and vehicle sales can lower truck purchase costs and transfer battery degradation and residual value risks to specialized operators.
However, the swapping model also presents complex challenges. Issues such as battery leasing contracts, insurance responsibilities, health status assessments, compatibility during route changes, and rights protection when fleets switch models or brands require clear regulations. The economic viability of swapping stations depends heavily on utilization rates, and factors like battery degradation, maintenance costs, leasing pricing, and insurance models could impact long-term feasibility.
Europe is already advancing regulations on heavy-vehicle carbon emissions, alternative fuel infrastructure, and battery passports, while also developing megawatt charging systems. The swapping model must prove its competitiveness in high-frequency, fixed-route scenarios to coexist with charging. The emergence of Swaptopus may compel European truck manufacturers to adjust product designs to align with CATL’s battery modules and swapping station interfaces.
Regulation and Industry Ecosystem: Can Europe Balance Openness and Efficiency?
European regulators must clarify key interface openness before large-scale fleet adoption. Battery health records should be portable, swapping station access rules must prevent unreasonable discrimination, and battery leasing and warranty terms should remain valid during fleet or model changes. Insurance and residual value assessment methods need sufficient transparency to ensure customers understand risk allocation.
Octopus Energy has proposed that battery inventories at swapping hubs could function as virtual power plants, charging and discharging based on grid conditions. However, freight operational needs must take priority over grid dispatch to avoid disrupting truck schedules and battery availability. Swaptopus’s deployment reflects China’s systemic advantages in freight electrification, integrating hardware, manufacturers, infrastructure, and policy to transform electric trucks from standalone products into an infrastructure ecosystem.
While Europe need not replicate China’s model, it must recognize that Swaptopus is not merely an energy refueling method but a platform attempting to define the relationships between trucks, batteries, stations, fleets, and power systems. The ability to balance openness and efficiency will determine the competitive landscape of Europe’s electric truck market.
