The global automotive integrated onboard charger market size was valued at USD 2.77 billion in 2022. The market is projected to grow from USD 4.44 billion in 2023 to USD 69.91 billion by 2030, exhibiting a CAGR of 48.3% during the forecast period.

The automotive integrated onboard charger is a technology that converts and regulates electrical power in electric and hybrid vehicles. It is a combined unit of onboard charger and DC-DC converter. The automotive integrated onboard charger or EV integrated charging control unit (ICCU), is an essential component in electric and hybrid vehicles. It enables efficient charging of the vehicle battery and conversion of high-voltage power from the battery to lower-voltage power required by other electrical systems in the vehicle.

The market is anticipated to experience significant growth in the coming years due to the adoption of electric and hybrid vehicles. In addition, the growing demand for advanced and efficient power conversion solutions with the advantage of reduced weight and complexity is expected to further drive market growth. The applications of automotive integrated onboard charger in diverse platforms are paving the way for new opportunities, which will augment the market's growth during the forecast period.


Reduced Demand of Electric Vehicles Hampered the Market Growth During the Pandemic

The COVID-19 impact has had a significant impact on this market. The global lockdowns and economic slowdown have disrupted supply chains, manufacturing processes, and consumer demand, leading to a slowdown in the growth of the EV industry as a whole.

The major impact of the pandemic on the market has been a decrease in demand for electric EVs, as consumers have been reluctant to make large purchases during economic uncertainty. This has led to a decrease in the production of electric EVs, which has, in turn, affected the demand for the integrated onboard charger. However, several governments increased focus on environmental sustainability and automotive emission reduction fueled the demand for EVs post-pandemic, propelling the market growth.

Developments in Wireless Integrated On-board Chargers (iOBCs) to Catalyze the Market Growth

Recently, Tesla has patented its wireless charging representing both conductive and inductive charging solutions. This might lead to the development of autonomous charging capability in EVs. Integration of a magnetic coupler with a transformer of DC-DC is also presented as a possible solution for a wireless iOBC system. Still, system architecture requires optimization to enhance operation efficiency.

In June 2022, Stellantis announced the successful charging of the Fiat 500 while running on a track in Italy, having inductive technology. Stellantis has also collaborated with HEVO to develop wireless fast charging of up to 50 KW capability. Hence, developments in wireless charging technology in combination with iOBC will propel the market growth.


Growing Adoption of V2G, V2L, and V2H will Drive the Market Growth of Integrated Charging Control Unit

Vehicle-to-Grid (V2G), Vehicle to Load (V2L) or Vehicle to Home (V2H) enables an EV to transfer its power to the electric grid, specific load or home for further energy usage applications. This technology is enabled by integrating a bi-directional, i.e. a two-way charger that allows the electricity to flow from the vehicle to a specific load.

Major EV manufacturers are focusing on deploying electric vehicles that support these applications due to rising adoption amongst end-users. For instance, In December 2022, Toyota revealed to set up a pilot plant in the U.S. to focus on V2G technology. The company has partnered with a Texas-based electric distribution group Oncor. Hence, the rising adoption of V2G, V2L or V2H will proliferate the market of automotive integrated onboard charger in the coming years.


Complexity in Integration of ICCU in Current EV Models is Expected to Restrain the Market Growth

Ever-changing technologies for EVs to maximize the entire system efficiency make it difficult for manufacturers to adopt them in existing EV fleets as it requires major hardware ecosystem changes inducing high R&D costs associated with newer designs.

The majority of current EV models have individual components such as AC/DC and DC/DC converters, which are configured OBC rather than as integrated OBC. This will require major design changes to incorporate ICCU, making it tough to implement in the current production line of EV models supplied by manufacturers. Hence, the supplier needs to develop an entirely new design to support the integration of ICCU in respective EV models. Therefore, integration challenges may restrain the market growth.
