NIO’s Power Swap Stations
But what does this CSU format mean for you?
It means that, essentially, as well as being able to charge your car the 'traditional' way (plug it in, wait for a bit, drive away), you'll be able to take advantage of NIO's Power Swap Stations (PSS).
These stations resemble stylish double garages, but with a crucial difference – they're equipped with automated technology that can remove the depleted battery from your car and replace it with a fully charged one, all while you remain comfortably seated in your vehicle.
Each station holds up to 14 battery packs and can charge them at speeds of up to 100kW each, ensuring minimal waiting times even if several batteries need recharging.
You can even reserve a fresh battery in advance through your car's interface when you're heading to a PSS.
The first European swap station opened in Norway, with Germany following in September 2022. As of February 2025, NIO has built an impressive network comprising 181 NIO Houses and 3,201 Power Swap Stations worldwide, including 970 stations on expressways in China alone.
Using a station couldn't be simpler: drive into the designated spot and tap the touchscreen to initiate the swap.
The car automatically positions itself precisely above the automated machinery that removes your depleted battery and installs a freshly charged one – with the entire process taking just five minutes."
But the speed of the swap isn’t its only draw for customers. As part of NIO’s ‘Battery as a Service’ system, the company can make its cars much more affordable by treating the batteries as a separate unit.
You can either opt for a car with a battery, or pay a few grand less and rent the battery for your car instead.
And of course, with swappable batteries, it doesn’t matter how big the battery is. It still takes the same amount of time to swap out a 75kWh pack as it does a 100kWh pack.
This also gives you a degree of flexibility.
Day-to-day, you can opt for the smaller battery and make the car lighter. But if you’re heading off on a long journey and mileage is your main concern, simply swap to the bigger pack for increased range and decreased anxiety.
Sounds pretty smart, right?
But NIO isn't alone in revolutionising EV recharging.
Fellow Chinese manufacturer BYD has recently unveiled its groundbreaking Super e-Platform charging system that could recharge compatible vehicles to 240 miles of range in just five minutes.
While NIO swaps batteries entirely, BYD's approach delivers an astonishing 1,000 kilowatts of power to specially designed vehicles with upgraded battery architecture and heat management systems.
Both innovations highlight how Chinese manufacturers are driving the future of electric mobility – eliminating traditional barriers to EV adoption through completely different but equally impressive technologies.
