Competition Status and Application Prospect Forecast of China's On-board Charger Industry from 2026 to 2030
Abstract：Competition Status and Application Prospect Forecast of China's On-board Charger Industry from 2026 to 2030
With the in-depth advancement of China's "dual carbon" strategic goals and the sustained high-speed growth of the new energy vehicle industry, on-board chargers, as a key accessory component of electric vehicles, are ushering in unprecedented development opportunities.
Under the strong impetus of national policies such as the New Energy Automobile Industry Development Plan (2021-2035) and relevant charging infrastructure policies, the on-board charger industry has transformed from a supporting and peripheral sector to a technological core. The optimized policy environment provides a stable development prospect for the industry. It is predicted that the market size of China's on-board charger will expand significantly from 2026 to 2030. The market size in 2025 is close to 18 billion yuan; based on the compound annual growth rate (CAGR) of new energy vehicle sales, it is expected to exceed 45 billion yuan by 2030, with the CAGR remaining in the range of 22%-24%.
In terms of product trends, integrated, high-power on-board charger (OBC) products with bidirectional charging and discharging (V2X) functions will become the mainstream. The proportion of on-board chargers compatible with 800V high-voltage platforms will rise from less than 15% in 2025 to more than 50%. From the technical route perspective, the current market is dominated by unidirectional AC/DC chargers, but bidirectional OBCs are accelerating their penetration with the emergence of new scenarios such as vehicle-to-grid (V2G) and household emergency power supply. The application of wide bandgap semiconductor materials such as silicon carbide (SiC) significantly improves energy efficiency and power density, driving products to evolve in the direction of lightweight and miniaturization.
In terms of core components, although the localization rate of key parts such as IGBTs, MOSFETs, and magnetic components is gradually increasing, there are still "bottleneck" problems in high-end automotive-grade chips and high-reliability capacitors, which restrict the supply chain security and cost optimization of the industry.
From the perspective of the industrial chain, the supply of upstream raw materials is relatively stable, but high-performance magnetic materials and automotive-grade semiconductors still rely on imports. The midstream manufacturing segment is fiercely competitive, forming a local enterprise cluster dominated by companies such as Xinrui Technology, Yingboer, Huichuan Technology, Weimaisi, and Fute Technology. Meanwhile, leading enterprises like Huawei and BYD, which are complete vehicle or technology giants, are accelerating vertical integration, reshaping the competitive landscape of the industry. The market concentration shows a trend of "steady improvement", with the CR5 proportion expected to rise from about 38% in 2024 to more than 50% by 2030. Leading enterprises are consolidating their advantages by binding customers through technological barriers.
In terms of application scenarios, passenger cars remain the largest demand source for on-board chargers, especially in the mid-to-high-end smart electric vehicle market, where the "all-in-one" electric drive system that highly integrates OBC, DC/DC, and PDU has become a standard configuration. At the same time, the demand for high-power and high-reliability OBCs in commercial vehicles (such as electric heavy-duty trucks and logistics vehicles) and special vehicles (such as sanitation vehicles and port AGVs) is growing rapidly, opening up a second growth curve for the industry.
However, the industry is also facing multiple challenges. The accelerated technological iteration has shortened the product life cycle to 2-3 years, leading to a sharp increase in the R&D investment pressure of enterprises. With the intensification of price competition, the gross profit margin of some low-end products has dropped below 15%, and the profitability of enterprises is under continuous pressure.
Looking ahead, enterprises need to focus on three strategic directions. First, accelerate the integration of new materials such as SiC and GaN with bidirectional charging and discharging technology to enhance product added value. Second, deepen collaborative development with original equipment manufacturers (OEMs), embed into the overall vehicle architecture, and realize customized supply. Third, expand overseas markets, especially emerging new energy vehicle markets such as Southeast Asia and Europe, and build a global production capacity and service system.
Overall, the period from 2026 to 2030 will be a critical stage for China's on-board charger industry to transition from "scale expansion" to "high-quality development". Enterprises with core technologies, supply chain resilience, and forward-looking layout capabilities are expected to stand out in the new round of competition.
