China’s NIO has pushed the battery swap model to new heights, completing 175,976 automated battery replacements in a single day and reinforcing the case for rapid energy replenishment over traditional charging.
Battery swap model drives NIO’s record-breaking performance
Instead of waiting to recharge, drivers simply replace a depleted battery with a fully charged one. For NIO, the battery swap system has been standard practice since 2018. On February 21, during China’s Lunar New Year, the company completed 175,976 battery swaps in 24 hours.
On paper, that translates to one swap every 0.5 seconds. In reality, the figure reflects total swaps divided by the number of operational stations across China in a single day, not the duration of an individual exchange.
How fast is a battery swap
A complete battery swap takes less time than refueling a conventional car. NIO’s current record stands at 2 minutes and 24 seconds per vehicle. A single station can handle up to 480 swaps per day.
The pace has accelerated rapidly. NIO reported 158,290 swaps on February 18, 165,898 on February 19, 170,305 on February 20, culminating in the February 21 record. When the system launched in 2018, the company managed roughly 100 swaps per day, each taking about five minutes and requiring human assistance to position the vehicle correctly. As of early February 2026, NIO has surpassed 100 million cumulative battery swaps.
Expansion of stations in China and Europe
In China, NIO has built an extensive infrastructure network. The company operates more than 8,600 energy stations, including over 3,700 dedicated battery swap stations. More than 1,000 are located along highways.
The network spans 550 cities and major expressways linking 16 metropolitan areas. In 2026, NIO plans to begin large-scale deployment of fifth-generation swap stations, with a target of adding 1,000 new units.
In Europe, the footprint remains limited, with roughly 60 stations concentrated in Germany and Norway, two of the region’s most electrified markets. In Madrid, Stellantis has launched a pilot battery swap station for the Fiat 500e.
How the battery swap process works
The system is highly automated. Through the vehicle’s navigation interface or the NIO app, drivers select the nearest station. The platform reserves a charged battery and assigns a queue slot before arrival.
Latest-generation stations are equipped with NVIDIA Orin X chips and LiDAR sensors dedicated to managing vehicle entry and enabling millimeter-level positioning for the robotic exchange.
Once the car is in place, a specialized robot simultaneously unscrews the bolts securing the battery to the chassis. A platform lowers, removes the depleted battery and stores it internally. A fully charged unit is then retrieved and lifted into position. The robot fastens the new battery, and the system performs an instant electrical diagnostic of the entire powertrain to ensure seamless integration.
Stored batteries are recharged using balanced charging protocols to extend lifespan and, when necessary, can feed electricity back into the grid during peak demand periods.
