Context: The Union Ministry of Road Transport and Highways is considering the electrification of the Golden Quadrilateral, connecting Delhi, Mumbai, Chennai, and Kolkata, as part of Vision 2030: PM Public Transport Sewa.

  • The plan, expected to be implemented over the next seven years, aims to boost e-mobility and deploy e-buses.
  • The proposal includes dynamic wireless charging technology, enabling EVs to charge while on the move.
  • This approach could potentially reduce the battery size, making EVs more affordable.

 

About Dynamic Wireless Charging Technology: 

Dynamic wireless charging technology refers to a system that enables electric vehicles (EVs) to charge while on the move by using base pads embedded under the surface of the road.

Unlike traditional stationary wireless charging, dynamic wireless charging allows EVs to receive power continuously as they travel, eliminating the need to stop charging.

 This technology relies on inductive transfer of energy, similar to stationary wireless charging. The base pads installed beneath the road’s surface generate a magnetic field, and a corresponding pad on the vehicle receives this energy, facilitating charging without physical connections.
