Problem Statement
- The Automobile Industry is transitioning to Electric Vehicles (EVs) to reduce fuel consumption, but charging should be facilitated for uninterrupted operation, despite the smooth operation of these vehicles.
- Charging points are now installed in parking areas to ensure smoother, longer-lasting electric vehicle (EV) charging.
- An Inductive Power Transfer System is one option, but for optimal efficiency, the primary coil should align with the secondary coil attached to the vehicle pad.
- EV alignment schemes use radio or magnetic positioning, but radio-based methods increase system complexity.
- Magnetic positioning-based schemes are less complex, requiring lower power level excitement.
- There is a need for the sensing system for aiding vehicle alignment.
Technology
Key Features / Value Proposition
