- As of June 22, 2026, Octopus Energy and CATL have launched a joint venture called 'Swaptopus' to build a European battery-swapping network for electric heavy-goods trucks.
- Swaptopus hubs deliver 500+ kWh in approximately 5 minutes — on par with diesel refueling — versus 3+ hours for conventional DC fast charging.
- The full network targets support for 300,000+ electric trucks and is designed to unlock over £30 billion (~US$34.37 billion) in private investment across 30+ European hubs by 2035.
- CATL's subsidiary Qiji Energy already operated 305 HGV battery-swap stations in China as of end-2025, giving Swaptopus a battle-tested operational template.
What Happened: The Swaptopus Announcement
5 minutes. That single figure — how long it takes to swap a fully depleted 500+ kWh battery pack out of a heavy-goods truck at a Swaptopus hub — is the entire commercial argument behind the joint venture Octopus Energy and CATL announced on June 22, 2026, at the Energy Tech Summit in London, held during London Climate Action Week. The two companies used the platform to formally declare 'Swaptopus,' a purpose-built battery-swapping network for electric trucks across the UK and continental Europe.
According to Google News, the venture's roadmap calls for the first UK mega-hubs to open in 2027, scaling to more than 30 hubs across Europe by 2035. At full build-out, the network is designed to support over 300,000 electric trucks and is projected to unlock over £30 billion (~US$34.37 billion) in private investment, per the partners' own targets. The joint venture also includes exploration of vehicle-to-grid (V2G) technology scaling across CATL's automotive partner network — a signal that this isn't purely a charging infrastructure play, but potentially a grid-scale energy storage business.
Oscar Luo, CATL's Head of Overseas Investment, was direct: "Our battery swap system can change the whole battery with more than 500 kilowatt-hour power in five minutes. That's shorter than filling diesel into the tank." He also noted that swapping incurs lower costs for electric HGVs compared to ultra-fast charging and enhances battery longevity. Greg Jackson, Octopus Energy Group CEO, framed the energy economics: "We'll have a massive stack of batteries at these stations that we can fill with the cheapest electricity at the cheapest times."
The Spec Sheet: What 500 kWh in 5 Minutes Actually Means
The 500+ kWh figure needs unpacking. A modern electric HGV typically carries a battery pack in the 400–600 kWh range to achieve viable long-haul range. Swapping that pack in under five minutes requires robotic arms, standardized battery form factors across truck manufacturers, and a hub stocked with pre-charged replacement packs. It is operationally closer to a container crane than a petrol forecourt — and it is already working at scale in Asia.
As of end-2025, CATL's subsidiary Qiji Energy operated exactly 305 battery-swapping stations for electric HGVs across China, according to technical coverage by Electrive published June 22, 2026. CATL has separately announced plans to expand to 2,500+ battery swap stations across 120+ Chinese cities by end-2026. That acceleration is the operational runway Swaptopus is importing to European soil.
The battery longevity argument has real fleet economics behind it. Swap stations charge depleted packs slowly and at partial state-of-charge levels optimized for cell health. Repeated DC fast-charging events — even high-power MCS-rated equipment — impose meaningfully higher thermal and electrochemical stress on large packs. Fleet operators who have modeled battery replacement costs at the 400–500 kWh scale understand that degradation directly compresses the residual value of owned fleet assets. For any operator with an owned-truck fleet on their balance sheet, that degradation curve is a live financial planning problem.

Why It Matters for European Freight Operations
Europe's regulatory calendar makes this more than a technology announcement. The EU's 2035 internal combustion engine ban and a 90% CO2 reduction target by 2040 for commercial vehicles are hard deadlines — not aspirational targets that logistics operators can defer. As of June 22, 2026, Europe's electric truck market is valued at $1.96 billion, according to market research cited in Swaptopus launch coverage. Analysts project that figure to reach $35.2 billion by 2032, a compound annual growth rate of 37.95%. The infrastructure capable of supporting that fleet transition does not yet exist at meaningful scale across Europe — which is precisely the opening Swaptopus is targeting.
Germany moved first on public funding: in December 2025, the German government approved €1.6 billion for heavy-duty charging infrastructure, including 350 stations with 2,400 ultra-fast charging points under its 'Power to Road' plan. That money flows toward conventional DC charging. Swaptopus is positioning swap technology as the complementary solution for operators who cannot absorb 3+ hours of downtime per vehicle per energy event on tight logistics schedules.
The global battery swapping market is projected to reach $22.72 billion by 2035. Research indicates the model becomes cost-effective when station utilization exceeds 43% and vehicle operating speed exceeds 32 km/h — thresholds that main European freight corridors are structurally positioned to meet. The V2G angle adds another revenue layer. Octopus Energy already partnered with BYD in 2025 for UK vehicle-to-grid deployment, establishing the integration framework. A Swaptopus mega-hub holding dozens of fully charged 500+ kWh packs is simultaneously a truck-service facility and a grid-scale energy storage asset. Jackson's comment about filling batteries "at the cheapest times" is the energy arbitrage thesis made explicit: buy renewable power overnight at low rates, hold it in the hub's battery inventory, discharge to the grid or swap into trucks during peak demand periods. AI-powered battery management systems are the operational backbone — machine learning algorithms schedule hub charging based on grid pricing signals, wind and solar generation forecasts, and truck arrival pattern predictions, determining optimal discharge timing automatically.
The Ownership Math: Battery-as-a-Service vs. Own-Your-Pack
For fleet operators modeling an electric HGV transition, Swaptopus introduces a financial structure worth stress-testing. The battery-as-a-service model — pay per swap rather than own the pack — removes a significant capital cost from the truck purchase while also transferring battery degradation risk to the network operator. A 500 kWh pack represents a substantial line item in any fleet's investment portfolio of owned assets; its residual value after five years of heavy freight use is considerably lower than acquisition cost, and that depreciation curve sits entirely inside a conventional owner's balance sheet.
The swap model converts capital expenditure into operating expenditure, which affects cash flow, balance sheet classification, and tax treatment differently depending on operator structure — a dimension that belongs in any rigorous financial planning analysis before committing to a fleet electrification path. As of June 22, 2026, Swaptopus has not publicly disclosed per-swap fee structures, so the direct cost-per-kilometer comparison with diesel or owned-battery electric trucks remains an open variable.
CATL, for context, holds 36.8% of the global EV battery market share as of 2023 data, making it the world's largest battery manufacturer by that metric. That supply-chain position means Swaptopus is not dependent on third-party cell sourcing — the venture controls its own battery economics from cell chemistry through swap-station inventory management.
In my read, the 2027 first-hub date is the genuine inflection point. The engineering is proven — 305 Chinese stations confirm that. What Europe needs to establish is whether truck OEMs will commit to shared battery form factors for swap compatibility. Scania's May 2026 demonstration of V2G technology for heavy commercial vehicles using Megawatt Charging System (MCS) equipment shows that at least one major manufacturer is thinking about bidirectional energy flow. Whether that thinking extends to standardized swap-compatible packs is the variable that will determine whether Swaptopus serves a broad European fleet or a proprietary niche.
Frequently Asked Questions
How does battery swapping work for electric trucks, step by step?
At a Swaptopus-style hub, the truck pulls into a dedicated swap bay. A robotic system disconnects and removes the depleted battery pack — which can weigh several hundred kilograms — and slides in a pre-charged replacement. The entire process takes approximately 5 minutes, according to CATL as of June 22, 2026. The depleted pack then charges slowly at the station, managed by an AI-driven battery management system that optimizes charging rate and state-of-charge for long-term cell health. Fleet operators pay per swap; the station operator owns, charges, and maintains all packs in the inventory pool.
Is battery swapping better than charging for electric trucks?
For high-utilization commercial freight operations, swapping has three meaningful structural advantages over DC fast charging: sub-5-minute turnaround versus 3+ hours for a full charge; lower battery degradation because packs charge slowly at the station rather than through repeated ultra-fast DC events; and battery-as-a-service economics that remove pack ownership — and its depreciation risk — from the fleet operator's balance sheet. The binding constraint is route coverage. As of June 22, 2026, Europe has zero commercial Swaptopus hubs; the first UK locations are targeted for 2027, with 30+ European hubs planned by 2035.
What companies make battery swapping stations for electric trucks?
As of June 22, 2026, CATL's subsidiary Qiji Energy is the leading operator of HGV battery-swap stations, with 305 stations active in China and a target of 2,500+ by end-2026. The Octopus Energy–CATL joint venture Swaptopus is the first announced attempt to build a commercial European network for heavy trucks. NIO's NIO Power subsidiary operates passenger-vehicle swap networks at large scale in China. Major EV charging infrastructure companies — ABB, Kempower, Tritium — focus on DC fast-charge hardware rather than swapping systems.
How much does a battery swapping station for trucks cost to build?
As of June 22, 2026, Swaptopus has not publicly disclosed a per-hub capital cost. The joint venture's overall investment target — over £30 billion (~US$34.37 billion) intended to be unlocked across the full 30+ European hub network — encompasses infrastructure, battery inventory, and ecosystem investment rather than individual station build cost alone. For rough comparison, Germany's government is funding approximately €1.6 billion for 350 conventional heavy-duty charging stations announced in December 2025, implying roughly €4.6 million per conventional charging site. Battery-swap hubs, with robotic systems and on-site battery inventories of pre-charged large-format packs, carry higher per-location capital requirements at build, offset by the per-transaction revenue from swap fees.
