研报 | 2025年第三季度电动车SiC逆变器装机量创单季新高，渗透率上升至18%

Core Insights - The article highlights the growth of the global electric vehicle (EV) market, particularly in the third quarter of 2025, where the installation volume of traction inverters reached 8.35 million units, marking a 22% year-on-year increase. Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) are the main contributors to this growth, with installation growth rates of 36% and 13.6% respectively [2][6]. Group 1: Electric Vehicle Market Growth - The global installation volume of traction inverters in Q3 2025 reached 8.35 million units, a 22% increase year-on-year [2]. - The growth rates for BEVs and PHEVs were 36% and 13.6% respectively, indicating strong demand in the EV sector [2]. - The integration of electric drive systems in vehicle chassis is increasing, with over 70% of inverter installations featuring a "3 in 1" or higher integration type [2]. Group 2: SiC Power Semiconductors - SiC power semiconductors are becoming key components in electric drive systems due to their compact size and higher voltage tolerance [5]. - In Q3 2025, the global installation volume of SiC inverters surpassed 1.5 million units, achieving a historical high [5]. - The penetration rate of SiC inverters in electric vehicles increased from 14% in 2024 to 18% in 2025, and reached 22% specifically for new energy vehicles [5]. Group 3: Market Dynamics and Challenges - 84% of SiC inverter installations were contributed by BEVs, with the remaining from PHEVs and Range-Extended Electric Vehicles (REEVs) [6]. - The Chinese market remains the largest for SiC inverters, accounting for approximately 75% of the installation volume, while demand in Europe and the US is showing signs of weakness [6]. - Despite the growth in inverter installation volumes, the overall market value in Q3 2025 decreased by 10% compared to the same period in 2024, reflecting pricing pressures from automakers [6].
