The burgeoning field of new energy vehicles (NEVs) in China is witnessing a significant shift towards heat pump air conditioning systems, which promise enhanced energy efficiency and reduced environmental impact. This technology is poised to redefine thermal management in electric vehicles, offering a greener alternative to traditional heating methods.
New energy vehicles (NEVs) are at the forefront of the automotive industry's efforts to mitigate environmental pollution caused by conventional fuel vehicles. A key distinction between NEVs and their traditional counterparts lies in their power systems, which necessitate a complete overhaul of thermal management and air conditioning systems.
Historically, industry giants such as Denso, Valeo, Hanon, and Mahle have dominated the global market for automotive thermal management, collectively holding over 50% of the market share in 2018, according to a report by JATO Dynamics. These companies have leveraged their technical prowess to maintain a competitive edge. However, as the automotive industry shifts towards electrification, this landscape is changing, with Chinese companies poised to challenge the status quo and potentially lead the market.
The thermal management system in NEVs encompasses not only the air conditioning system but also includes battery thermal management, electric motor control thermal management, and the cooling of other equipment. Unlike traditional vehicles, NEVs use electric energy to power their air conditioning systems, with heating options including Positive Temperature Coefficient (PTC) heaters and heat pump systems. Heat pumps are gaining traction due to their superior energy efficiency compared to PTC heating, leading to their rapid adoption in NEVs.
Chinese companies are quickly gaining ground in the heat pump air-conditioning market, capitalizing on their agility and keen market sense to meet the evolving demands of both domestic and international new energy automobile manufacturers. The transition from engine-driven to battery-powered air conditioning systems in NEVs necessitates innovative technical solutions, providing an opportunity for Chinese firms to potentially "overtake on the curve" in the competitive landscape of automotive thermal management.
The market value of air-conditioning systems in NEVs is significantly higher than that of traditional vehicles, with estimates suggesting a value of approximately 7,000 to 10,000 yuan per vehicle, nearly double that of conventional vehicles. The air-conditioning system alone in NEVs is valued at around 3,950 yuan per vehicle, a stark contrast to the 1,610 yuan per vehicle in traditional fuel vehicles. With China's NEV penetration rate target set at 25% by 2025, domestic sales of NEVs are expected to reach 7.1 million, creating a market potential of about 50 billion yuan for thermal management systems, of which 28 billion yuan could be attributed to air-conditioning systems. The adoption of carbon dioxide heat pump technology could further enhance this market potential.
The air conditioning system is a critical component of the thermal management system in NEVs. The main differences between the thermal management systems of NEVs and traditional vehicles are:
The heating options for NEVs include PTC and heat pump modes. For cooling, electric compression refrigeration is the standard, while heating primarily involves PTC (liquid/air) and heat pump systems. For instance, Tesla's Model X utilizes an air PTC heating scheme, which is more efficient than liquid PTC systems.
In conclusion, as China continues to advance in the NEV market, the heat pump air conditioning technology is set to play a pivotal role in shaping the future of electric vehicles. With increased investment and innovation, Chinese companies are well-positioned to lead this transformative era in automotive thermal management.
