Group 1: Industry Performance - Excluding seasonal and year-over-year declines, power device companies have entered a phase of positive year-over-year profit growth [4]. - In Q1, the overall price decline of products was less than in 2024, benefiting leading listed companies from increased penetration in high-barrier markets such as automotive and computing [4]. - The overall profitability of the industry remains stable, with medium and low-voltage products showing steady year-over-year growth [4][9]. Group 2: Market Trends - The sales of new energy vehicles (NEVs) in March increased by 40% year-over-year, with a total of 1.24 million units sold [14]. - The penetration rate of NEVs reached 42.4% in March, indicating strong market demand [14]. - The share of main drive power modules with a peak power of over 200 kW in NEVs has increased from 9% in 2022 to 25% in early 2025 [17]. Group 3: Product Development - The penetration rate of SiC MOSFETs in NEVs has risen to 18.9% as of early 2025, reflecting a shift towards higher power segments [19]. - The competition among domestic IGBT module suppliers is intensifying, with local manufacturers capturing approximately 86% of the market share [20]. - The number of 800V models is increasing, which is a significant driver for the penetration of SiC devices [24]. Group 4: Charging Infrastructure - The cumulative increase in charging stations in the first quarter of 2025 was 931,000 units, representing a year-over-year growth of 30.1% [39]. - Public charging stations saw a significant increase of 75%, while private charging stations grew by 14.6% [39]. - The average power of charging stations is expected to continue increasing due to ongoing technological advancements [39].
