On-board Charger Market Size, Share & Trends Analysis Report By Power Output (Less than 11 kW, 11 kW to 22 kW, More than 22 kW), By Vehicle Type (Passenger Car, Buses, Vans, Medium & Heavy-Duty Vehicles, Boats, Others), By Sales Channel (Original Equipment Manufacturer (OEM), Aftermarket), By Propulsion Type (Battery Electric Vehicle (BEV), Plug-in Hybrid Electric Vehicle (PHEV)) and By Region (North America, Europe, APAC, Middle East and Africa, LATAM) Forecasts, 2026-2034

On-board Charger Market Size

The global on-board charger market size was valued at USD 11.18 billion in 2025 and is projected to grow from USD 13.16 billion in 2026 to USD 48.35 billion by 2034, registering a CAGR of 17.67% during the forecast period from 2026 to 2034. Asia Pacific dominated the on-board charger market with a market share of 44.2% in 2025.

Over the forecast period, the escalating global demand for electric vehicles will be the primary driver of demand growth for onboard chargers. An onboard charger converts alternating current (AC) from charging stations to charge a vehicle's battery into direct current (DC). The increased number of AC charging stations installed in emerging business sectors contributes further to the growth of the onboard charger market. Silicon carbide semiconductor technology is being increasingly adopted to produce onboard chargers because of its total thickness and 98 % efficiency rate. As a result, a few companies are focusing more on providing silicon carbide onboard chargers that are more powerful and productive, creating new opportunities for market growth. The onboard charger allows you to control the charging current and voltage, extending the battery's life. Chargers provide constant current or voltage charging, both of which are simple to use and have their own set of advantages and disadvantages.

Increasing government initiatives for the construction of charging infrastructure for electric vehicles are driving the growth of the Electric Vehicle onboard charger market. However, the lack of standardisation of EV charging and the rise in the installation of fast DC chargers may hinder the growth of the Electric Vehicle onboard charger market. During the forecast period, developing a two-way onboard charger (V2G) for future electric and plug-in hybrid vehicles is predicted to provide potential opportunities for the Electric Vehicle onboard charger market. Moreover, sales of electric vehicle (EV) onboard chargers have decreased dramatically during the few months of the coronavirus epidemic due to the global decline in vehicle demand. During the global shutdown, the import/export of raw materials required for EV chargers and production activities in the EV industry have been halted to prevent the spread of coronavirus.

Segmentation Analysis

In 2021, the 11 kW to 22 kW category led the Market and accounted for over 41 % of the global revenue. The 11-22 kW triphase AC chargers can fully charge an electric vehicle in two to four hours. A tri-phase AC charger is typically utilised as a public charging station. Transport & Environment statistics indicate that 61 % of European public chargers are tri-phase AC chargers. Less than 11 kW is predicted to experience the most growth during the projection period. In the future, most electric vehicles are anticipated to incorporate 6 kW to 11 kW onboard chargers. Shortly, 98.2 % of onboard chargers will be 6 kW to 11 kW rather than 3 kW to 5 kW, according to data published by Open Systems Media. In addition, the benefits provided by less than 11 kW onboard chargers, such as better charging efficiency and maximum performance, are anticipated to boost the expansion of the market.

In 2021, the passenger car category led the Market and contributed more than 35.0% of worldwide revenue. Increasing global sales of electric passenger vehicles are anticipated to increase demand for onboard chargers. According to data published by HIS Market, sales of plug-in passenger vehicles in the United States will increase to 5.5% of the market share in 2020. In addition, plug-in passenger car sales in Europe accounted for 7.7 % of the market. The bus segment is anticipated to experience the most rapid expansion during the projection period. In buses, an onboard charger is utilised to convert AC to DC for battery charging. The increase in global sales of zero-emission buses is anticipated to contribute to the segment's growth. Sustainable Bus, an online publication focusing on the Market for electric buses, predicts that by 2040, 83 % of all buses will be electric.

In 2021, the BEV category led the Market and accounted for more than 67 % worldwide revenue. A plug-in charged battery propels a Battery Electric Vehicle (BEV). The increase in BEVs is fueling the segment's expansion. Volkswagen, Audi, and Mercedes-Benz have the most significant market share in the BEV class, followed by other manufacturers. Volkswagen held 17.4 % of the BEV market in 2021, followed by Mercedes-Benz with 14.9 %. The PHEV segment is anticipated to experience the most increase during the projection period. Various Plug-in Hybrid Electric Vehicles (PHEVs) manufacturers are adopting onboard chargers with a power output between 3 and 3.7 kW, fueling category growth. The batteries of vehicles such as the Hyundai Sonata PHEV, Kia K5 PHEV, and Outlander PHEV are charged by onboard chargers. PHEVs are experiencing exponential expansion worldwide. In 2021, BYD, a Chinese producer of electric vehicles, sold 7,126 PHEVs, a 60 % increase from the 4,454 PHEVs it sold in 2021.

Regional Insights

Asia Pacific is A Dominant Region with A 38% Market Share

In 2021, the Asia Pacific area was responsible for more than 38 % of worldwide revenue. This gave it a commanding lead in the industry. The increase in government initiatives to promote the sale of electric vehicles in countries such as China and India contributes to the acceleration of market growth in the area. For example, the sales quotas imposed by the Chinese government for the years 2019, 2020, and 2021 are one of the primary factors pushing the sales of EV onboard chargers in the country. These percentages will be in place for 2019, 2020, and 2021. In China, electric vehicles (EVs) that use onboard chargers include, amongst others, the Tesla Model 3, the BYD Qin Pro EV, and the GAC Aion S.

Europe is the Fastest-Growing Region

For the projection period, Europe is anticipated to experience tremendous growth. The market participants in Europe are persistently making attempts to increase their electric vehicle (EV) offerings, which is increasing demand for onboard chargers as a direct result. In line with the BMW vision, the automaker intends to electrify its sport utility vehicles (SUVs), four-door sedans (sedans), and Mini vehicles in Europe by 2030. At the same time, a surge in subsidies granted for the purchase of electric vehicles is also one of the significant aspects driving the market growth in the region. This is one of the primary reasons driving the market growth in the region.
