Wireless EV Charging: An Innovative Solution Facilitating Smooth Transition toward Electric Mobility

Highlights:

• Introduction
• Reasons behind the growing preference for wireless EV charging
• R&D projects and product launches in the sector

Wireless EV charging refers to a technology that allows an electric vehicle to charge without any physical cable and plug connection. The growing emphasis of governmental agencies and private companies on expanding EV infrastructure to facilitate a smooth transition toward electric mobility has increased the demand for this new technology. Also called inductive charging, wireless charging uses electromagnetic fields to transfer energy between the specialized coils embedded in the station and the vehicle, thereby eliminating the need for any physical cord or plugging point. This technology has been gaining a lot of popularity in the US, China, India, and many European countries where the sale of EVs is likely to rise significantly in the coming years.

Increasing adoption of wireless EV charging strengthening the industry’s foothold

Recently, WiTricity, one of the biggest players in the wireless EV charging industry, found in a survey that over 95% of EV owners are willing to switch to wireless charging. Moreover, it also underlined that 70% of the respondents were open to buying an EV if this new technology was readily available. The study concluded that the increasing adoption of wireless charging systems is not only important for the industry but also for the entire EV sector.

The primary reason behind the rising preference for wireless charging solutions is the ease and convenience offered by this technology. EVs can recharge effortlessly just by being near the station, without the need for cables, pads, or mats. Furthermore, these hubs allow the charging of multiple vehicles simultaneously, thereby reducing waiting times and the possibility of traffic congestion.

Along with this, in the last few years, several leading consumer electronics companies and automobile businesses have jointly initiated R&D projects to address some of the challenges in the industry. For instance, one major problem associated with this technology is that the charging speed and power efficiency offered by these wireless charging stations are much lower than their conventional counterparts. To address these issues, companies have invested heavily in advanced resonant inductive coupling solutions and magnetic resonance systems that transfer energy over electromagnetic fields efficiently. Moreover, innovations in radio frequency (RF) charging have also played an important role in creating favorable conditions for the growth of the industry. Additionally, EV infrastructure developers are increasingly integrating renewable energy sources such as solar and wind to power these stations, thus promoting sustainability and green practices in the long run.

Innovations by multinational giants and start-ups creating favorable conditions for growth

The wireless EV charging market was valued at $466 million in 2023 and is anticipated to gather a revenue of $12.4 billion by 2033, rising at a stunning CAGR of 38.6% during 2024-2033. The R&D initiatives funded by multinational automotive corporations, start-ups, and research institutes are expected to play an important role in the growth of the sector in the coming period. For instance, in April 2024, Simactricals, an electric vehicle solutions startup incubated at IIT Kanpur, India, announced its success in developing a stable wireless EV charging system. The company, initially, designed a charging solution for UAVs by collaborating with Defense Research and Development Organization (DRDO), the premier defense research institute in India. Banking on the success and acclaim received for the UAV charging technology, the company has expanded its reach by developing a charging system for electric passenger vehicles, bikes, and three-wheelers. The startup had received huge government funding and support for this project.

Similarly, in August 2024, researchers at the Oak Ridge National Laboratory (ORNL), Tennessee released a press statement announcing the development of a wireless EV charging solution. For this project, the research institute partnered with Volkswagen Group, an automobile manufacturer based in Germany. The 270-kW wireless charging system features advanced components to prevent overheating, current leakages, and short circuits. As per ORNL, this new product is expected to help other companies design their systems in the near future, thus accelerating the transition toward wireless charging.

Winding up, the increasing number of electric vehicles sales in countries like the US, China, and India is predicted to contribute to the expansion of the wireless EV charging industry. Furthermore, the recent advancements and the R&D projects initiated by reputed organizations and companies are anticipated to impact the market positively.
