Beijing, China – May 11, 2025:
At a battery swap station near Beijing’s Olympic Sports Centre, a Nio electric car owner watches as a robotic platform removes the vehicle’s drained battery and installs a freshly charged one—all in less than five minutes. With the Bird’s Nest Stadium looming nearby, this swift exchange is part of China’s broader strategy to treat battery swap stations as the EV equivalent of traditional gas stations.
Battery swapping, the process of replacing depleted EV batteries with fully charged units, has been trialled in China for years. Unlike conventional charging—which can take anywhere from 30 minutes to several hours—this approach offers a near-instant solution to range anxiety. Thanks to its dominance in lithium-ion battery manufacturing and state-backed innovation, China has established the world’s most advanced battery swap infrastructure.
By 2023, China had installed more than 3,500 swap stations, including over 3,300 by EV maker Nio alone. Battery giant CATL has also partnered with Sinopec to build a nationwide “battery-swapping ecosystem.” The technology is especially prevalent among commercial fleets—nearly half of China’s electric heavy-duty trucks sold in 2023 supported battery swapping.
Despite the impressive progress, the system is not without obstacles. Compatibility remains a challenge, as only EVs with swappable batteries can participate. Furthermore, ownership concerns linger. Swapping means relinquishing the battery a consumer paid for, often receiving an older replacement. To address this, some manufacturers are decoupling battery ownership from the vehicle, offering battery rentals instead.
Historically, the concept isn’t new. Companies like Israel-based Better Place pioneered the model in the 2000s but went bankrupt in 2013 due to limited market adoption. Tesla also experimented with the idea but discontinued it, citing low consumer interest.
Still, China’s unique EV ecosystem is giving battery swapping renewed life. While fast-charging infrastructure is rapidly expanding—with companies like BYD now offering charging systems that deliver 400 km of range in five minutes—the swap model remains a compelling complement, especially for taxis and logistics vehicles that can’t afford long charging downtimes.
By the end of 2026, over 13 million Chinese EVs are expected to support 800V fast charging. But battery swaps may still find relevance globally, particularly in emerging EV markets where range anxiety persists and charging infrastructure is underdeveloped.
For now, China is betting on both horses: an ultra-fast charging future and a plug-and-play battery swap model. Whether the rest of the world follows suit remains to be seen.
