Electric Air Conditioning Compressor For EV
Unlike traditional fuel vehicles that rely on engine belt-driven compressors, new energy vehicles (BEVs, PHEVs, REVs) lack an engine as a power source. Our Electric Air Conditioning Compressor (EACC) is engineered with a built-in permanent magnet synchronous motor, directly powered by the vehicle's high-voltage battery. It serves as the core power component for in-vehicle cooling and auxiliary heating (in heat pump systems), ensuring comfortable cabin temperature while maximizing energy efficiency and extending vehicle range.

Electric Air Conditioning Compressor for EV
Leading Solution for Electric Vehicle Cooling & Heating | Energy-Saving | High-Voltage Adaptable | Intelligent Control
Introduction: The Heart of NEV Air Conditioning System
Unlike traditional fuel vehicles that rely on engine belt-driven compressors, new energy vehicles (BEVs, PHEVs, REVs) lack an engine as a power source. Our Electric Air Conditioning Compressor (EACC) is engineered with a built-in permanent magnet synchronous motor, directly powered by the vehicle's high-voltage battery. It serves as the core power component for in-vehicle cooling and auxiliary heating (in heat pump systems), ensuring comfortable cabin temperature while maximizing energy efficiency and extending vehicle range.
Core Advantages: Redefine NEV Climate Control Performance
High Energy Efficiency
Adopts high-performance permanent magnet synchronous motor with an Energy Efficiency Ratio (COP) of over 3.2, far exceeding traditional compressors. Variable frequency speed regulation technology enables precise adjustment of rotational speed according to cooling/heating demands, avoiding energy waste and reducing air conditioning system energy consumption by 30%-50%.
Wide High-Voltage Adaptability
Compatible with mainstream NEV high-voltage platforms (300V-800V), perfectly matching the technical requirements of fast-charging models. Equipped with advanced high-voltage insulation protection design, passing strict high-voltage safety tests to ensure stable and safe operation.
Low Noise & Comfort
Mainstream scroll compression structure with optimized dynamic balance design, ensuring low vibration and ultra-quiet operation (noise ≤ 60dB). Creates a peaceful and comfortable driving environment, meeting the comfort requirements of mid-to-high-end NEV models.
Intelligent & Reliable
Integrated intelligent controller, realizing seamless communication with vehicle VCU (Vehicle Control Unit) and air conditioning ECU. Supports precise temperature control, fault self-diagnosis (overcurrent, overheating, undervoltage protection), and real-time operation status monitoring.
Extreme Climate Adaptability
Wide operating temperature range: -40℃ ~ 85℃, adapting to extreme climates such as cold northern regions and hot tropical areas. Passes rigorous environmental adaptability tests to ensure stable performance in various working conditions.
Heat Pump Synergy
In heat pump air conditioning systems, it cooperates with four-way valves to switch refrigerant flow direction, transferring external environmental heat to the cabin for winter heating. Compared with PTC heating, it significantly reduces energy consumption and extends cruising range in low-temperature environments.
Working Principle
1. Power supply: The vehicle's high-voltage battery provides power, and a built-in permanent magnet synchronous motor drives the compressor's scroll/piston to compress the refrigerant.
2. Refrigeration cycle: The compressor converts a low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant enters a condenser, where it gives off heat and turns into a liquid. The liquid refrigerant then reduces its pressure through an expansion valve and enters the evaporator, where it absorbs heat from the vehicle interior and turns into a gas. It then returns to the compressor to complete the cycle, cooling the vehicle interior.
3. Heat pump heating cycle: By reversing the flow direction of the refrigerant through a four-way valve, the compressor transfers heat from the external environment (even at low temperatures) to the interior of the vehicle, providing efficient winter heating.
