Core Viewpoint - The Chinese automotive fuse industry is experiencing rapid growth driven by the booming automotive sector, particularly in the new energy vehicle (NEV) market, with a projected market size of 1.6 billion yuan in 2024, representing a year-on-year growth of 38.17% [1][10]. Industry Overview - Automotive fuses, also known as automotive circuit breakers, are critical components in vehicle electrical systems, designed to protect against overloads and short circuits by automatically disconnecting the circuit [2]. - The industry has evolved through four main stages: initial technology accumulation, standard transition, domestic replacement, and the current phase of intelligent transformation [3][4]. Industry Development History - The industry began with technology accumulation from the 1950s to the 1970s, followed by a transition to international standards in the 1980s, leading to improvements in product quality and reliability [3]. - From 1996 to 2010, domestic manufacturers began to close the gap with foreign brands, while the period from 2011 onwards has seen a shift towards high-voltage and intelligent fuses due to the rise of NEVs [4]. Industry Supply Chain - The upstream supply chain includes raw materials such as conductive metals (copper, silver), insulating materials (ceramics, glass), and arc-extinguishing materials [6]. - The midstream involves the manufacturing of automotive fuses, while the downstream is primarily the automotive industry [6]. Market Size - The automotive fuse market in China is expected to reach 1.6 billion yuan in 2024, with high-end products like incentive and intelligent fuses seeing a penetration rate exceeding 15% [10]. Key Companies' Performance - The competitive landscape is characterized by foreign brands dominating the high-end market, while domestic companies like Zhongrong Electric are gaining market share through technological advancements [12]. - Zhongrong Electric has achieved over 20% global market share in high-voltage fuses for NEVs, while Haoli Technology focuses on cost advantages in the traditional and mid-range NEV markets [12]. Industry Development Trends 1. Technological Upgrades and High-End Breakthroughs - The industry is moving towards higher voltage and current capabilities, with new products exceeding 1000V being developed [17]. - Intelligent fuses with integrated communication interfaces and self-diagnostic functions are becoming essential for safety in autonomous driving and vehicle networking [17]. 2. Diversification of Market Demand and Scene Expansion - The application of automotive fuses is expanding beyond traditional vehicles to include the entire new energy vehicle supply chain, with increasing demand in charging stations and energy storage systems [19]. 3. Deepening Domestic Replacement and Global Layout - Domestic manufacturers are accelerating the replacement of foreign brands and expanding globally, with companies like Zhongrong Electric establishing subsidiaries abroad to mitigate trade barriers [20].
