Efficient Use Guide for New Energy Vehicle Air Conditioning: Easily Extend Driving Range
With the widespread adoption of new energy vehicles (EVs), driving range has become one of the most critical concerns for owners. As a key system directly affecting battery energy consumption, the scientific use of air conditioning is crucial. Unlike traditional fuel-powered cars, which use engine waste heat and belt-driven compressors, NEV air conditioning systems are fully powered by electricity. Whether cooling or heating, they consume energy directly from the battery. Therefore, mastering some efficient air conditioning usage techniques not only ensures a comfortable cabin but also significantly extends the driving range.

1. Understanding NEV Air Conditioning Systems
NEV air conditioning relies primarily on an electric compressor for cooling. When the temperature drops, the refrigerant circulates through the compressor to absorb heat from the cabin. For heating, common technologies include PTC (Positive Temperature Coefficient) resistors and heat pump systems. Notably, while PTC heating is simple to operate, it consumes a significant amount of energy. On the other hand, heat pump technology is more energy-efficient, reducing winter electricity consumption by 30%-50%. Therefore, when selecting a vehicle, opting for a model equipped with a heat pump air conditioner can provide substantial energy-saving benefits.
2. Summer Cooling Tips
1) Set the Right Temperature
Avoid setting the air conditioning temperature too low. It is recommended to set the cooling temperature at around 26°C (78.8°F). Studies show that lowering the temperature by just 1°C can increase energy consumption by 5%-8%. Keeping it at 26°C ensures comfort while reducing unnecessary energy use.
2) Properly Switch Between Internal and External Circulation
After entering a sun-heated vehicle, use the external air circulation mode first to expel hot air. Once driving, switch to internal circulation to prevent hot external air from continuously entering, improving cooling efficiency.
3) Use Remote Pre-Cooling
Utilize a smartphone app to pre-cool the vehicle before entry. This helps avoid the need for immediate maximum cooling when getting in, leading to lower power consumption and smoother energy transition.
3. Winter Heating Strategies
1) Choose Vehicles with Heat Pump Air Conditioning
Compared to traditional PTC heaters, heat pump systems extract heat from external air, significantly improving efficiency and reducing power consumption in cold weather. Choosing a vehicle with a heat pump system is the best way to reduce winter energy loss.
2) Moderate Temperature Settings and Preheating Measures
Setting the cabin heating temperature between 20-22°C (68-71.6°F) provides warmth while avoiding excessive power usage and cabin dryness. Additionally, preheating the battery and cabin while charging before departure reduces the heating load while driving.
3) Utilize Localized Heating
Use seat and steering wheel heating to provide direct warmth while reducing the need for overall cabin heating. This helps minimize energy consumption.
4. Daily Efficiency Improvements
Beyond seasonal air conditioning adjustments, small details in daily use can further enhance efficiency:
- Regular Maintenance: Clean air filters and the condenser regularly to maintain optimal performance.
- Optimal Parking Choices: Park in shaded areasto reduce cabin heat buildup, minimizing the need for high-powered cooling upon entry.
- Manage High-Speed Driving and Windows: Keep windows closedon highways to reduce air resistance and unnecessary energy loss.
- Plan Long-Distance Trips Wisely: Schedule charging stops during long trips, using the breaks to adjust cabin temperature, easing range anxiety caused by continuous air conditioning use.
Conclusion
The air conditioning system in new energy vehicles plays a crucial role in both comfort and driving range. Whether ensuring efficient cooling in summer or energy-saving heating in winter, drivers can optimize their experience through smart temperature settings, air circulation control, preheating, and localized heating. As advanced technologies like heat pumps become more widespread, China EVs will continue to offer more economical, eco-friendly, and comfortable travel experiences.
