The claim is part of BYD’s push to make electric vehicles faster and more practical in extreme weather, where low temperatures can significantly affect battery performance and charging speeds. Chinese electric vehicle maker BYD says its latest Flash Charging technology can charge an electric vehicle from 20% to 97% in just 12 minutes at temperatures as low as -30 degree celsius.
If the company’s reported performance can be consistently replicated in real-world conditions, faster charging in extreme cold could make EVs more practical in colder regions. BYD’s charging push extends beyond battery technology. It is a specific performance claim for the company’s Flash Charging technology and second-generation Blade Battery under the stated test conditions.
Because low temperatures can reduce battery efficiency and increase charging times, bYD’s cold-weather claim is particularly notable. BYD says its Flash Charging system can take a battery from 10% to 97% in nine minutes under normal-temperature conditions, while its test at -30 degree celsius achieved a charge level of 20% to 97% in 12 minutes. The company said on 28 August 2026 that it had opened its 10,000th Flash Charging station in China, marking a major expansion of its high-power charging network. The company says its Flash Charging system can deliver charging power of up to 1,500 kW, although the charging speed experienced by an individual vehicle depends on factors including the vehicle’s battery, charging system and operating conditions. However, the 12-minute figure should not be interpreted as a universal charging time for all BYD vehicles.
The company’s second-generation Blade Battery is designed to maintain high charging performance in very cold conditions, according to information published on BYD’s official website.
