Unlike conventional fuel-powered commercial vehicles, the air conditioning compressor in new energy commercial vehicles is centered on electrification and high efficiency. It is no longer belt-driven by the engine but powered directly by the high-voltage traction battery. Consequently, the technological focus has shifted entirely to high energy efficiency and low power consumption to alleviate range anxiety. Currently, electric scroll compressors dominate the market, while disruptive new technologies are rapidly emerging.
1. Electric Vehicle Air Conditioning Compressor Mainstream Technology: Electric Scroll Compressor
- Working Principle: Comprising a fixed scroll and an orbiting scroll, the electric motor drives the orbiting scroll to compress refrigerant in progressively shrinking chambers. The integrated motor-compressor design ensures a compact structure and flexible installation.
- Key Advantages:
- High Efficiency: Compared with belt-driven systems, it offers superior energy transfer efficiency; combined with variable frequency control, it precisely adjusts speed according to thermal load, significantly reducing energy use.
- Wide Voltage Range: Product series cover mainstream voltages from 24V to 800V, compatible with various battery platforms for both BEV and PHEV applications.
- Low Noise & Comfort: Without engine-induced vibration and noise, it operates smoothly and quietly, enhancing cabin comfort.
- Applications: Widely used in battery-electric and hybrid large/medium buses, heavy-duty trucks, light trucks, and construction machinery.
2. EV Air Conditioning Compressor Future Trends
- Wide-temperature Heat Pumps & Eco-friendly Refrigerants: To address winter range loss, heat pump systems using low-GWP refrigerants like R410a, R1234yf, and natural refrigerant CO₂ (R744) are gaining traction.
- Extreme Miniaturization & Light weighting: Through material innovation and structural optimization, volume and weight are continuously reduced without compromising performance.
- High-voltage Platforms & Integration: The rise of 800V fast-charging architectures drives demand for high-voltage electric compressors; meanwhile, highly integrated “compressor + controller” solutions are accelerating commercialization.
3. Key Selection Criteria
- Voltage Matching: Ensure the compressor voltage matches the vehicle battery platform (e.g., 24V, 48V, 72V, 144V, 320V, 800V, etc.).
- Cooling/Heating Capacity: Select appropriate displacement (e.g., 18cc–86cc) and power rating based on vehicle type (bus/truck) and cabin space.
- Coefficient of Performance (COP): Prioritize models with higher COP to reduce power consumption and extend driving range.
- Environmental Adaptability: Choose compressors capable of operating in extreme temperature conditions (e.g., -40°C cold start) depending on the operating region.
- Refrigerant Type: While R134a remains current mainstream, low-GWP alternatives such as R1234yf, R410a, and CO₂ (R744) are clear regulatory trends.
