EV truck battery swapping is set to scale across Europe after Octopus Energy and battery maker CATL formed a joint venture, Swaptopus, to build large hubs where electric lorries exchange depleted packs in minutes instead of waiting hours for a charge. The companies say the network could eventually support more than 300,000 electric trucks and unlock over £30 billion in investment.
Why EV truck battery swapping comes first
Heavy electric trucks face a different problem from passenger cars. Their packs are enormous, and recharging them mid-shift can sideline a vehicle for a long stretch precisely when an operator needs it earning revenue. Battery swapping sidesteps that by letting a driver drop a flat pack and collect a fully charged one in a matter of minutes.
The scale of these packs explains the appeal. CATL's largest commercial-vehicle batteries can reach 1,000 kWh, roughly 20 times the capacity of a typical electric passenger car. Charging that much energy quickly demands huge power draw at a single site; swapping spreads the charging across many packs sitting in a hub, so trucks never have to wait for the grid.
"Electric trucks already beat diesel on running costs, the challenge is keeping them moving," said Greg Jackson, CEO and founder of Octopus Energy Group. The first large hubs are expected to begin operating in 2027, starting in the UK.
- First hubs: 2027, beginning in the UK
- Target: more than 30 large hubs across Europe by 2035
- Capacity goal: support 300,000+ electric trucks
- Largest CATL commercial packs: up to 1,000 kWh
- Estimated investment unlocked: more than £30 billion
How the swapping hubs would work
At a swapping station, depleted packs are removed and slotted into charging racks while a charged pack is fitted to the truck. Because the trucks themselves are never tied up charging, the bottleneck shifts from the vehicle to the hub, where energy can be topped up steadily and cheaply at off-peak times.
That model has already been proven at scale in China, where swapping networks for both cars and commercial vehicles are well established. CATL, the world's largest battery manufacturer, supplies much of that hardware, while Octopus brings energy retailing and grid expertise to the European rollout.
Vehicle-to-grid ambitions and grid services
Beyond freight, the partners are examining energy storage and grid services. One proposal would expand vehicle-to-grid technology across CATL's manufacturing partners, letting future fleets return electricity to the grid during peak demand.

Swaptopus argues the stations could double as virtual power plants, charging and discharging packs when the grid needs balancing. A large bank of truck batteries sitting in a hub is, in effect, grid-scale storage that can absorb cheap renewable power and feed it back when demand spikes. "We have field-proven this technology in China, and we are delighted to bring it to the UK and Europe," said Dr. Robin Zeng, chairman and CEO of CATL.
Why it matters for European road freight
Road freight is one of the hardest sectors to decarbonize, and downtime is the enemy of any haulage business. By cutting refueling to minutes and tying the hubs into wider grid balancing, the plan attacks both the cost and the practicality barriers at once. It ties clean transport to broader energy and infrastructure strategy as Europe pushes to cut emissions from heavy trucks.
The targets are ambitious and depend on hubs, vehicles, and standardized packs all arriving together. But with a battery giant and a major energy supplier behind it, Swaptopus represents one of the most concrete attempts yet to make electric trucking work at continental scale.
EV truck battery swapping: quick FAQ
How fast is an EV truck battery swap?
A swap takes minutes rather than the hours a full recharge of a large commercial pack can require, letting trucks return to the road quickly.
When will the first hubs open?
The first large hubs are expected to begin operating in 2027, starting in the UK, with a target of more than 30 hubs across Europe by 2035.
