Every morning, as freezing winds blow across his construction site in northern China, Liu Jianhong gathers his workers for a cup of hot tea. Liu, whose business in Shaanxi province often operates beyond the reach of power grids, plugs a hairdryer-like charger into his hybrid electric vehicle, a crossover from Chinese automaker BYD Co. The other end of the charger connects to his kettle. A few minutes later, it lets out a whistle and tea time begins.
“With the help of the electric car, we can drink tea whenever and wherever we want. My workers are over the moon,” says Liu, 57, who used to schlep hot water in a too-small thermos from a nearby village each day, forcing his employees to take turns enjoying tea breaks. Liu’s EV has come to the rescue before, like when he needed to charge a power drill at a newly-built home he hadn’t realized wasn’t connected to a utility. “If it were not for my car, I would have wasted all the time and energy going there,” he says.
As EVs with plugs proliferate, what’s known as “two-way charging” is becoming table stakes in the electric diving experience. Drivers like Liu are among a growing number of people thinking about their EV as not only a cleaner and cheaper way to get around, but also a source of electricity in day-to-day life and during emergencies. In China, where more than one in five new cars sold this year was electric, more people than ever are experiencing a future in which vehicles double as power banks, and EV makers are pitching their products as “batteries on wheels.”
Since Liu Xiao, 38, started hooking up his camping stove to his hybrid electric car during weekend getaways, he no longer worries about his kid getting too close to an open flame. The camping enthusiast, who lives in the eastern coastal city of Dalian, used to bring a fuel canister on trips, but he says his EV, made by China’s Li Auto, provides “a huge advantage over that.” In summer months, Liu’s family also uses the car to run an electric fan while watching movies on a projector screen.
“It has given us so much fun,” he says.
EV sales are already soaring in China, but the promise of fun — and convenience — could be a helpful boost in markets like the US and Europe, where electric options are still catching up. About 300 million electric vehicles will need to be on the road globally by 2030 for the world to achieve net zero emissions by mid-century, according to the International Energy Agency. As of last year, just 16.5 million units had been sold. Adoption everywhere remains limited by range anxiety, a lack of charging infrastructure, and the higher upfront cost of EV models compared to similar gasoline-powered vehicles.
Two-way, or bidirectional, charging can be done by loading an EV with power outlets, known as vehicle-to-load (V2L). Automakers that include Japan’s Mitsubishi Motors, China’s BYD and South Korea’s Hyundai also offer EVs that power homes and businesses — known as vehicle-to-home charging, or V2H — and even send power back to the grid (vehicle-to-grid charging, or V2G).
