BEIJING - Take a road trip in an electric car, and you know the
juicing up routine. You pull off the highway, park at a charging
station, plug in the car … and wait. If you're lucky, it's about half an
hour. Sometimes, it's longer.
In China, one company can get
you back on the road in minutes. I had the opportunity to see how, with
Jason Wu, an executive at NIO Power, an EV maker.
A few weeks ago, I sat in a roomy SUV, while Wu, in the driver's seat, spoke to the vehicle. "Hi Nomi."
"I'm here," the car responds in a cute, child-like voice. Wu asks the car to initiate a battery swap, and the car takes over.
We drive into a small structure that looks like a one car garage
without front and back walls. The car instructs Wu to take his foot off
the brake, remove his hands from the steering wheel and to not open the
doors.
"If you feel nervous, I'm here," it says. Then, it automatically backs into the car port.
The company recognizes that long charging times are keeping people from buying EVs
"This is fully-automated battery swapping," Wu says.
No more waiting to charge up. The car is about to get a fresh battery.
NIO
has recognized that long charging times are one of the main reasons
keeping people from buying EVs – not only in China, but all over the
world.
The company has installed nearly 4,000 battery swap stations like this around the world, most in China.
NIO EVs are popular in China, but competition is fierce. The company has roughly 4% market share in vehicles that are primarily electric. Its battery swapping is still something of a novelty.
But it's an attractive solution in a country where many drivers live in apartments that don't always have charging ports.
"On February 6, 2026, our total battery swapping network had
provided 100 million swaps," said Wu. That's since the first swap
station opened in Beijing eight years ago. "This fully demonstrates that
battery swapping, as a power replenishment method, has already become
very mainstream."
China's highways have 1,000 of these NIO swapping stations
NIO says it's saved drivers more than 83 million hours. Other companies are trying it, including CATL, the world's biggest battery maker. In the U.S., some see it as a useful potential solution for electric trucks, which have long charging times.
Wu
extolls battery swapping as convenient, fast and safe. And he says it's
good for the health of the batteries. There's also no need to get out
and fuss with cables or gas pumps. Nio owners have the option of buying
or renting the battery in their car, and they can charge the normal way,
too.
For road trippers, NIO has put over 1,000 swapping stations along China's highways.
Back at the battery changing station, the car stops in the port.
It lifts up a tiny bit, and jostles around, followed by a muffled,
methodic clanking sound and then, silence. The gray metal floor under
the vehicle opens, and a machine rises to the undercarriage.
The
car's entire battery pack, which weighs about 1,100 pounds, or about as
much as a grand piano, is unbolted and whisked away, underground. It
goes into a closed room on the side of the swapping station where it is
plugged in to charge for a future user.
Under the car, there
are a few clicks and clanks as a fresh battery is lifted into place and
bolted securely to the vehicle. The system runs some diagnostic checks.
And that's it.
"OK, you can see. Green light," Wu says. "The battery swap is done."
A
screen on the swapping station shows how long the whole process took:
Three minutes and eight seconds … or about the same time it might take
to fuel up at a gas station.
