Source-This post on Dynamic wireless charging technology has been based on the article “Induction charging on ‘golden quadrilateral’ can make travel between India’s metros cheap, easy” published in “Down to Earth” on 23 January 2024.
Why in the news?
Dynamic Wireless Charging Technology, The Union Ministry of Road Transport and Highways is mulling over the electrification of the Golden Quadrilateral, as part of its Vision 2030: PM Public Transport Sewa.
What is Dynamic Wireless Charging Technology?
1) Dynamic wireless charging technology refers to a system that enables electric vehicles (EVs) to charge while moving by using base pads embedded under the surface of the road.
2) Dynamic wireless charging allows EVs to receive power continuously as they do not need to stop to refuel or recharge.
3) This technology relies on inductive transfer of energy. The base pads installed under the road’s surface generate a magnetic field, and a corresponding pad on the vehicle receives this energy, ensuring charging without physical connections.
What are Advantages and Disadvantages of This Technology?
| Advantages | Disadvantages |
| 1) Continuous electric vehicle battery charging can minimize range anxiety because vehicles can charge as they move, potentially boosting their market share. | 1) More research is needed to boost the power levels and efficiency of the existing technology. |
| 2) It can reduce the need for plug-in charging stations, saving space. | 2) Finding the space for the charging pad and equipment on the underside of an existing vehicle can be challenging. |
| 3) Ongoing charging allows for a smaller EV battery size with reduced weight, helping to decrease the cost of EVs and conserving materials. | 3) Overcoming technological challenges related to vehicle body interference with power transfer efficiency. |
| 4) It would help in decarbonising the transportation sector. | 4) Retrofitting infrastructure with this charging technology for widespread implementation would be costly. |
