The mushrooming demand for electric vehicles is encouraging electric vehicle charging system manufacturers to focus on developing technologically advanced and innovative variants. Moreover, with the surging concerns being raised over the deteriorating environmental conditions, many electric vehicle manufacturers are making huge investments in research and development (R&D) projects in order to fuel advancements in the electric vehicle technology. For instance, Fiat Chrysler Automobiles N.V. announced in July 2019 that it intends to make an investment of $788 million (EUR 700 million) for developing a manufacturing line for the newer models of its Fiat 500 minicar.

This manufacturing line will enable the production of around 80,000 units every year. These investments are causing a sharp fall in manufacturing costs, which is, in turn, leading to the production of affordable electric vehicles. This is subsequently pushing up the demand for on-board chargers. These projects have led to the development of batteries having increased power densities. Besides, the increasing deployment of alternating current (AC) charging stations in emerging economies is also fueling the expansion of the on-board charger market.

This is primarily ascribed to the deployment of numerous AC chargers, as they are majorly used at homes for charging electric vehicles. As these chargers are cheaper than the other variants, they are being preferred by people throughout the world. Some of the major on-board charger manufacturing companies across the world are NXP Semiconductors N.V., Delta-Q Corporation, Delphi Technologies PLC, Eaton Corporation plc, Delta Electronics Inc., Avid Technology Inc., Toyota Motor Corporation, Infineon Technologies AG, and LG Chem Ltd.

Hence, it can be said without any doubt that the demand for on-board chargers will surge sharply in the forthcoming years, primarily because of the growing deployment of electric vehicles and the development of technologically advanced charging systems, on account of the surging investments being made by industry players across the world.
