DRIVING FACTORS

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.

RESTRAINING FACTORS

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.
