Octopus Vitality, the UK’s largest power supplier, has teamed up with CATL, the world’s largest EV battery maker, to carry Chinese language-style battery swap stations to Europe. The pair declare they wish to roll out a community of services throughout the continent, focused at maintaining electrical vehicles on the highway for longer. Every hub can be able to servicing 1000’s of vehicles a day, changing depleted cells with recent ones in “minutes.” Such a system might even be quicker than filling a standard truck with diesel, and it is definitely quite a bit cheaper.
We have all heard EV boosters speak up battery swapping because the inevitable answer to vary anxiousness, particularly with out having to rinse your tools with quick charging. In concept, you possibly can simply rock up at a station, dump your drained cells and put freshly-charged ones in, all within the time it takes you to go to the lavatory. In fact, the reality was by no means as easy: The excessive value of batteries and the engineering required meant it by no means fairly labored in addition to that they had hoped, and even Tesla deserted the thought a decade in the past.
However the system has loads of uptake in Asia, with vehicles in a position to dump off and decide up new batteries in a matter of minutes. In 2025, CATL partnered with Asian oil firm Sinopec to roll out a large battery-swap community across China. There are even consumer-facing battery swap services, together with these run by automotive maker Nio and Taiwanese scooter firm Gogoro, which has put in an unlimited community of swap stations.
Octopus and CATL, nonetheless, assume that it is most likely much more viable for trucking, and I am tempted to agree. In any case, if there’s one a part of the worldwide transport ecosystem by which EVs do not but make sense, it is heavy business. Massive vehicles and ships carrying equally hefty masses require much more power to maneuver round, and batteries add much more weight to the image. It is the rocket equation: The heavier your load, the extra power you want, and in EVs meaning extra batteries, rising your weight even additional. It is why this sector is extra prone to be won over by hydrogen fuel cells, given the power densities and refuel instances.
But when vehicles use smaller batteries, and drivers are assured that they’ll get a fully-charged substitute at each stage of their journey, then the equation begins to shift. William Rowe, CEO of the Octopus / CATL three way partnership, named Swaptopus, says that the battery stations can cost their cells “when the grid wants it.” In truth, having a big quantity of batteries doubtlessly sitting idle would additionally allow every hub to behave as a small energy plant. In fact, that will not thrill the logistics and transport firms who’re renting the cells and would possibly take subject with their cycle life getting used to spice up Octopus’ power community.
Swaptopus says the primary UK “mega hubs” will open in 2027, and it will be fascinating to see what number of main truck firms join. In any case, their buying selections are taken over a for much longer time period and infrequently depend upon ensures of infrastructure being in place for them to make use of. However given Octopus and CATL’s weight, you’d anticipate greater than a handful to throw their lot in with the brand new enterprise.
