In 2025, the new energy vehicle electric heating sector is experiencing dual drivers of technological iteration and market explosion. With the continuous rise in global electric vehicle penetration, the EV heater, particularly the electric vehicle PTC heater, as a core thermal management component, is seeing surging demand. According to the latest data from QYResearch, the global market for HVCH reached $984 million in 2024 and is projected to exceed $2.488 billion by 2031, with a compound annual growth rate of 14.4%.
Technology Upgrade: Thick-Film Heating and Multi-Modal Coordination Become Trends
The industry is witnessing diversified technological pathways. While traditional PTC heaters remain mainstream, thick-film heating technology—due to its higher efficiency and smaller size—has become a R&D focus for automakers like Tesla and BMW, promising to enhance low-temperature range performance. At the same time, battery thermal management systems are evolving toward "refrigerant direct cooling + liquid cooling coordination." For example, BYD’s blade battery uses a dual-channel design adapted to extreme environments from -30°C to 60°C.
Market Outlook: China Becomes a Core Growth Engine
The Asia-Pacific region accounts for 46% of global demand. Driven by Chinese policies, the annual demand for PTC coolant heater units is expected to reach 16 million sets by 2025. The industry is transitioning from single-function products to intelligent and integrated systems. Future competition is likely to focus on predictive temperature control and material innovations, particularly in high-efficiency variants such as the high voltage coolant heater and EV coolant heater.
