Kiwis are optimistic about on-road dynamic wireless charging for electric vehicles (EVs), despite concerns about safety and costs, a recent survey shows.

Dynamic wireless charging technology, which allows EVs to charge while driving, promises to revolutionise the current charging infrastructure.

A survey of 1,150 existing and prospective EV drivers conducted by University of Auckland researchers reveals that 93% of respondents are hopeful about the technology.

Doctoral candidate Ramesh Majhi, senior lecturer Prakash Ranjitkar, and senior research fellow Selena Sheng designed the survey to explore views on wireless charging technology.

“Dynamic wireless charging may not be practical for meeting urban transportation demands. However, it offers significant advantages for intercity travel by reducing EV drivers’ reliance on plug-in charging stations that often cause detours on highways,” Majhi said.

The study, titled "Analysing electric vehicle users' intention to use dynamic wireless charging facilities: A study from New Zealand," highlighted that urban users are more likely to adopt the technology compared to their rural counterparts.

Social influences, such as the behaviour and choices of peers, also play a significant role in drivers' decisions to use the technology.

However, despite the enthusiasm, concerns about data privacy, electromagnetic radiation, and potential costs associated with wireless in-road technology remain.

Sheng emphasised the importance of addressing these concerns for the successful integration of dynamic wireless charging into the transportation network.

“The movement toward adopting EVs for their sustainability in reducing greenhouse gas emissions faces hurdles regarding inadequate charging infrastructure,” Sheng said.

“This is where in-road charging lanes will be of benefit, and it’s essential for policymakers to know how best to manage the rollout of this kind of technology in future and to ensure people’s concerns are understood, and hopefully alleviated.”

The study's insights are crucial for developing effective measures and policies to support the adoption of dynamic wireless charging, providing a more convenient and sustainable solution for EV users.
