CATL's Battery Swapping Strategy for Heavy-Duty Trucks vs. Europe's Megawatt Charging Network

When CATL announced its partnership with Octopus Energy to build battery-swapping stations for heavy-duty trucks across Europe, my first reaction was not admiration for CATL's expanding global footprint. Instead, a more practical question came to mind: Which truck manufacturers will actually use these battery-swapping stations?

Would CATL ultimately need to bring Chinese truck manufacturers and their battery-swapping vehicle platforms into Europe, effectively exporting China's entire battery-swapping ecosystem?

More fundamentally, the battery industry is inherently characterized by long supply chains, heavy capital requirements, and extensive vertical integration. This business model places significant pressure on every participant across the value chain. Without barriers such as technical standards, intellectual property protection, regulatory oversight, and market access requirements, it is theoretically possible for a single company to establish unprecedented global dominance —covering everything from mineral extraction and battery manufacturing to power generation, energy storage, charging and battery-swapping infrastructure, station operations, second-life battery applications, recycling, and even carbon-credit revenues. Such a company would effectively control the entire electric mobility ecosystem.

The only battery-swapping truck currently known in the EU.

According to a report published by Truck Technology Frontier on July 1, 2026, several European truck manufacturers are reportedly cautious—or even resistant—toward the joint venture established by CATL and Octopus Energy.The venture, known as Swaptopus, aims to build a battery-swapping network for heavy-duty trucks across Europe. However, the initiative has also sparked broader discussions regarding industry standardization, OEM autonomy, and the strategic implications of adopting infrastructure led by a Chinese battery supplier.Under its current roadmap, Swaptopus plans to launch its first battery-swapping hubs in the United Kingdom in 2027, with a long-term goal of deploying 30 stations across Europe by 2035.

The debate is not centered on battery swapping as a technology itself, but rather on what European truck manufacturers would have to sacrifice in order to make such a system commercially viable.

A truly interoperable battery-swapping ecosystem would require competing OEMs to standardize and coordinate vehicle platforms, battery architectures, mechanical interfaces, electrical systems, software, battery management systems (BMS), and communication protocols. Such a level of openness represents a significant departure from the product differentiation strategies traditionally pursued by European commercial vehicle manufacturers.

Sun Jie, an automotive analyst at S&P Global Mobility, told Nikkei Asia that: "European OEMs are unlikely to embrace standards led by CATL, as doing so would reduce their control over product development and weaken their ability to differentiate themselves from competitors."

Thomas Fabian, Commercial Vehicles Director at the European Automobile Manufacturers' Association (ACEA), argues that Europe's priority should be to accelerate the deployment of open and interoperable charging solutions capable of supporting cross-border freight operations, rather than locking fleets into proprietary battery-swapping standards.David Cebon, Director of the Centre for Sustainable Road Freight at the University of Cambridge, has been even more outspoken. In his view, major European truck manufacturers—including Volvo, Scania, Mercedes-Benz, MAN, and DAF—are unlikely to relinquish decades of accumulated battery-related intellectual property or adopt a common architecture dominated by CATL.

These concerns are not merely hypothetical—they stem from the underlying economics of the battery-swapping business model.Under a battery-swapping model, fleet operators typically lease batteries instead of purchasing them outright. Battery ownership shifts from the vehicle manufacturer to the infrastructure operator, reducing one of the OEM's most important points of product differentiation while transferring a degree of commercial control to whoever governs the swapping standard.Against a backdrop of increasing geopolitical tensions across global automotive markets, it is understandable why European manufacturers remain cautious about adopting an ecosystem ultimately controlled by a Chinese battery supplier.

At the same time, a series of recent announcements from Europe's leading truck manufacturers has further strengthened confidence in the charging-based pathway.

Renault Trucks has increased the maximum driving range of its E-Tech T to 660 kilometers. According to operational data collected from approximately 70,000 connected tractor units across Europe, around 80% of real-world long-haul freight operations can already be completed within that range. When drivers use their legally mandated 45-minute break after every 4.5 hours of driving for high-power charging, that figure increases to approximately 90%.From the perspective of European OEMs, these results suggest that megawatt charging technology is becoming sufficiently capable to meet the vast majority of long-haul transport requirements, reducing the need for an entirely different battery-swapping infrastructure.

Meanwhile, Mercedes-Benz Trucks has released operational data from more than 3,000 analyzed long-haul journeys, further validating the practicality of its eActros electric truck platform for daily long-distance freight operations.MAN Truck & Bus has also demonstrated a stable charging current of 3,000 amperes under the NEFTON research project, paving the way for future 3-megawatt (MW) charging technology. According to the project's findings, the Megawatt Charging System (MCS) could eventually deliver approximately 400 kilometers of driving range in just 10 minutes.

in theory, charging performance at this level would significantly reduce—or potentially eliminate—concerns over vehicle downtime during long-haul operations.

For CATL and Octopus Energy, however, the business case revolves around two fundamental arguments: minimizing vehicle downtime and lowering the Total Cost of Ownership (TCO) for fleet operators.Battery swapping reduces refueling time to a level comparable with conventional diesel refueling, while battery leasing removes the battery from the truck's upfront purchase price altogether, significantly lowering initial capital expenditure.For many fleet operators, this reduction in upfront investment remains one of the biggest barriers to fleet electrification.

China offers perhaps the strongest real-world validation of this business model. Supported by a relatively mature battery-swapping infrastructure, the country's adoption rate of new-energy heavy-duty trucks has substantially outpaced that of Europe.It is worth noting that China's battery-electric truck market is still dominated by plug-in charging, with charging and battery-swapping vehicles accounting for roughly a 7:3 sales ratio. For example, in May 2026, approximately 15,700 battery-electric tractor units using conventional charging were sold, compared with around 6,300 battery-swapping models.

Overall, China's new-energy heavy-duty truck penetration reached 29% in 2025, while the corresponding figures were only 0.9% in the United Kingdom and 4.4% across Europe during the first quarter of 2026.Although battery swapping generally carries higher operating costs than conventional charging, it remains less expensive than diesel fueling and therefore continues to offer an attractive economic proposition for fleet operators.

CATL is not simply introducing a new technology to Europe — it is bringing a business model that has already undergone substantial real-world validation in China.

The company currently operates more than 300 battery-swapping stations for heavy-duty trucks across China. Through its subsidiary Qiji Energy, CATL has collaborated with OEMs such as FAW Jiefang and Shaanxi Heavy Duty Truck to launch more than 30 standardized battery-swapping truck models, while also partnering with leading logistics companies including JD Logistics, Transfar Logistics, and DHL.According to CATL's roadmap, the Qiji battery-swapping network reached 305 stations in 2025 and is expected to expand to approximately 900 stations by the end of 2026, covering China's major "Five Horizontal, Five Vertical" freight corridors. By 2030, the company aims to establish an "Eight Horizontal, Ten Vertical" nationwide swapping network spanning approximately 180,000 kilometers and serving roughly 80% of China's trunk freight capacity.

Octopus Energy contributes a different but equally important set of capabilities, including local market expertise, electricity grid relationships, permitting experience, and policy credibility. Under today's increasingly stringent regulatory environment, these assets would be difficult for a Chinese industrial company to build independently in Europe.

Ultimately, however, the success of battery swapping in Europe depends less on CATL or Octopus than on whether Europe's major truck manufacturers are willing to participate in a common ecosystem.So far, such industry-wide alignment has yet to emerge.

Meanwhile, Europe's charging infrastructure continues to advance rapidly. The EU's Megawatt Charging System (MCS), introduced in February 2025, enables truck batteries to be charged from 20% to 80% in approximately 30 to 40 minutes — almost perfectly matching the mandatory driver rest periods required under European regulations.

From the perspective of European OEMs, charging may not be perfect, but it is increasingly becoming "good enough" to support long-haul freight operations.

Europe is also investing heavily in its own charging ecosystem.Milence, the joint venture established by Daimler Truck, TRATON Group, and Volvo Group, is deploying a high-performance public charging network for long-haul battery-electric trucks across Europe.

The company ultimately plans to build around 1,700 high-capacity charging points powered by renewable electricity, with megawatt charging forming the backbone of the network. Under the EU's Alternative Fuels Infrastructure Facility (AFIF), Milence aims to deploy at least 284 MCS charging points across 71 locations in ten EU member states by 2027.

Meanwhile, Scania's charging subsidiary Erinion plans to install approximately 40,000 private and semi-public charging points at customer sites, while MAN and energy provider E.ON intend to build around 400 public charging stations across roughly 170 locations throughout Europe.Together, these investments demonstrate that Europe is steadily building its own open charging ecosystem for heavy-duty electric transport.

The emerging consensus within Europe's commercial vehicle industry is that charging may not be the perfect solution, but it is sufficiently mature, sufficiently open, and already well underway. As a result, most European OEMs see little incentive to replace it with a battery-swapping ecosystem led by an external technology provider.In that sense, the ultimate success of Swaptopus may depend less on technological feasibility than on market timing.

CATL and Octopus are introducing a business model that has already demonstrated considerable success in China. The challenge, however, is that they are offering an alternative solution to a European industry that increasingly believes it has already found one of its own.
