What is the actual winter range of the BYD Han EV?

[AlinaFitz]

The actual winter range of the BYD Han EV is approximately 601 kilometers. Factors affecting range: The vehicle's range is influenced by multiple factors, such as battery high-low temperature technology, optimization of battery BMS technology, upgrades to the vehicle's energy recovery system, lightweight body design, and energy-saving technologies in hardware equipment. Additionally, external driving conditions, air resistance coefficient, mechanical transmission efficiency, vehicle weight, number of passengers, and other factors can also impact the actual range of an electric vehicle. Reasons for reduced range in winter: Lower external temperatures cause lithium-ion battery materials to deposit more under cold conditions, making it difficult for them to move quickly and fully convert into electrical energy.

Last winter in Harbin with temperatures at -20°C, my BYD Han EV, which has an official range of 605 km, saw its actual range drop to around 350 km. Over the past few months, I've noticed that using the heater in cold weather consumes a significant amount of power, especially during traffic jams when the battery drains quickly. Battery efficiency decreases in low temperatures, so I recommend preheating the car for about 20 minutes using the mobile app before heading out, which can improve the range by approximately 5%. Maintaining a steady speed of around 60 km/h and keeping tire pressure at the recommended level can also help save power. For those frequently driving long distances, carrying a portable charger or planning charging station locations in advance is advisable to avoid getting stranded. Overall, in sub-zero temperatures, the range typically falls between 300 to 450 km, depending on specific weather conditions and driving habits.

From a technical perspective, the winter performance degradation of BYD Han EV's battery is a critical issue. Lithium iron phosphate (LFP) batteries exhibit lower discharge efficiency in cold temperatures, resulting in an actual range reduction of 20% to 30%. While the official claimed range is 605 km, it may drop to just over 400 km in sub-zero conditions. Contributing factors include ambient temperature and HVAC usage intensity—using the heater can consume an additional 15% of battery power. Drivers are advised to use Eco mode and avoid sudden acceleration; parking in a garage is recommended to slow battery cooling. Newer models may feature a heat pump system for slight improvement. Overall, winter range fluctuates significantly, typically between 350 to 450 km, requiring assessment based on road conditions.

As an average user commuting daily with a BYD Han EV in Shanghai where winter temperatures average around 5°C, I experience a range of approximately 450 km. This is about 100 km less than in summer, mainly due to increased air conditioning usage and the battery's difficulty with cold starts. During the commute, especially in stop-and-go traffic during peak hours, the battery drains noticeably faster. It's advisable to develop habits like preheating the battery for 5 minutes before departure, setting the air conditioning to a moderate temperature rather than too high, and making frequent use of regenerative braking to recover energy, which can slightly extend the range. Winter range may be unstable, but maintaining between 400 to 500 km is manageable with regular charging, ensuring no impact on daily convenience.
