A bidirectional on-board battery charger (OBC) is an electric vehicle component that allows charging the vehicle's battery from the grid while also enabling the battery to supply power back to the grid or external loads. It supports vehicle-to-grid (V2G) and vehicle-to-home (V2H) functionalities, improving energy management and grid stability.
The primary types of bidirectional on-board battery chargers are silicon-based and silicon carbide-based. A silicon-based bidirectional on-board battery charger uses silicon semiconductors to both charge a vehicle battery and feed energy back to the grid or home. It is compatible with various battery types, including lithium-ion batteries, lead-acid batteries, nickel-metal hydride (NiMH) batteries, and solid-state batteries. These chargers support multiple charging technologies, such as alternating current (AC) charging, direct current (DC) charging, wireless charging, and hybrid-ID (Hy-ID) charging. They are applied in electric vehicles (EVs), renewable energy systems, power backup systems, and electricity grid services, serving diverse end users including residential, commercial, industrial, and public charging stations.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.

The bidirectional on-board battery charger market size has grown rapidly in recent years. It will grow from $1.37 billion in 2024 to $1.60 billion in 2025 at a compound annual growth rate (CAGR) of 17.0%. The growth in the historic period can be attributed to rising adoption of electric vehicles, increasing government incentives for electric vehicle charging infrastructure, growing demand for energy-efficient transportation, escalating fossil fuel costs, and increasing consumer awareness of sustainable mobility.
The bidirectional on-board battery charger market size is expected to see rapid growth in the next few years. It will grow to $2.97 billion in 2029 at a compound annual growth rate (CAGR) of 16.7%. The growth in the forecast period can be attributed to increasing deployment of smart charging infrastructure, rising demand for backup power solutions, expansion of commercial fleet electrification, growing investment in grid modernization, and rising preference for home-based bidirectional charging solutions. Key trends in the forecast period include development of high-efficiency converters, integration with fleet management systems, innovation in battery lifetime optimization, advancement in multi-vehicle charging solutions, and development of vehicle-to-home (V2H) applications.
The rising adoption of electric vehicles (EVs) is expected to drive the growth of the bidirectional on-board battery charger market going forward. Electric vehicles are automobiles powered fully or partially by electricity, offering a cleaner alternative to conventional internal combustion engines. The increase in EV adoption is fueled by growing environmental awareness, as consumers seek to reduce greenhouse gas emissions and mitigate climate change. Bidirectional on-board battery chargers enhance electric vehicles by allowing efficient charging from the grid and enabling energy to flow back to support vehicle-to-grid applications and optimized energy management. For instance, in February 2024, according to the U.S. Department of Energy, a US-based federal agency, monthly EV sales showed consistent year-over-year growth over the past three years, with peak monthly sales reaching approximately 50,000 vehicles in 2021, rising to around 80,000 in 2022, and surpassing 100,000 in 2023. Therefore, the increasing adoption of electric vehicles is driving the growth of the bidirectional on-board battery charger market.
