Local extreme minimum temperature can reach -48°C, China's northernmost NIO battery swap station goes into operation in Heihe, Heilongjiang
IT之家 November 15 news, NIO announced that on November 15, China's northernmost NIO battery swap station — the Heihe Free Trade Zone NIO battery swap station — officially went into operation.
Heihe is China's northernmost prefecture-level city. Its winters are long, with an annual freezing period of about 200 days, and the extreme minimum temperature can reach -48°C.

The company stated that common charging equipment is prone to frost and ice formation at low temperatures, battery activity attenuation, and a sharp drop in charging efficiency. The NIO battery swap station body uses an insulated enclosure structure to form an independent constant-temperature chamber; the battery compartment inside the station is equipped with a 7×24-hour continuous constant-temperature thermal management system, keeping the batteries in the compartment stably within the optimal operating range of 15–30°C, reducing the slowdown in charging speed caused by the external low temperatures of dozens of degrees below zero; the battery swap machinery automatically preheats, ensuring the entire battery swap process operates stably under extreme low temperatures. Even in extreme low-temperature environments, NIO, ONVO, and firefly users can still enjoy a 3-minute battery swap without getting out of the car throughout the process, and without waiting for charging in the cold wind.
IT之家 has learned that in October this year, NIO successively completed "battery swap stations in every city" in Jilin and Liaoning provinces. As of today, NIO has cumulatively deployed 490 charging and battery swap stations in Northeast China, including 102 battery swap stations, 388 charging stations, and 1,378 charging piles.
NIO has cumulatively deployed 9,855 charging and battery swap stations nationwide, including 4,262 battery swap stations, 5,593 charging stations, and 32,669 charging piles. The company claims that the number of charging and battery swap stations it has built ranks first in the industry.
