BYD Han 2025 flies for 405 km in winter testing

A recent testing of the BYD Han 2025 Fly version, a model designed to address user concerns about new energy vehicle winter range, efficiency, and charging time, has been revealed. The test results show that this BYD model can maintain stability on both extremely low-temperature (hence "low-winter" or "" in Chinese) and high-low temperature (also called "double cold" season) zones.

The comparison of two extreme test conditions will serve to bring you the specific data below:

Tested vehicle

The 2025 BYD Han Fly version used was equipped with a 38.88 kWh LFP battery pack, featuring single-motor front-wheel drive formality.

The manufacturer's CLTC battery range is specified at 405 km in winter test conditions.

###寒冷区（Cold Zone）

- 温度：-20℃ to -15℃    
- Test route: From Hegang Bailing, Longjiang County, Heilongjiang Province to Cold Extremes River
- Endurance distance and percentage: 178.4 km (44% test accomplishment rate)
- Efficiency: Average energy consumption of 23.64kWh/km
- Charging situation: Complete cycle time: 100 minutes; full charge time from -30 to 80 percent: 50 min.

Low-winter Zone（Cold Winter Area）

  Temperatures ranging from 5℃ to 15℃
- Energy consumption data:
   - Total energy input: 40.8kWh 
   - Average energy consumption of 13.45kWh/100km
- Complete cycle time: 76 minutes（Up to 17 minutes more than the cold region）

Both two tests have proved that even in extremely low temperatures (below minus 20 degrees), BYD Han 2025 maintains excellent range and efficiency. In addition, compared with the same period of charging process between two zones, BYD Han Fly could shorten nearly an hour to achieve fast charging.
