MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202541117829 A) filed by A. Prabha; K. S. Margaret; and S. A. Engineering College, Chennai, Tamil Nadu, on Nov. 27, 2025, for 'wireless power transfer for electric vehicles.'
Inventor(s) include A. Prabha; and K. S. Margaret.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "Wireless Power Transfer (WPT) is an emerging technology aimed at contactless energy transmission for electric vehicles (EVs), eliminating the need for physical charging cables. This, system uses electromagnetic induction or resonant inductive coupling to transfer electrical energy from a primary coil (transmitter) embedded in a charging pad to a secondary coil (receiver) installed in the vehicle. The inverter section converts DC supply to high-frequency AC to generate a magnetic field, which induces current in the secondary coil. WPT offers convenience, safety, and potential for dynamic charging, enabling EVs to charge while in motion or parked. The efficiency of power transfer depends on coil alignment, resonant frequency tuning, and distance between the coils. This study explores the principle, components, design considerations, and advantages of WPT for EVs, highlighting its role in promoting sustainable and user-friendly electric mobility. Keywords: Contactless energy transmission."
