An Advanced Wireless Changing System for Electric Vehicles
- Field
- Electronics
- Patent
- IP00705
Key Problem and Market Opportunity
- The use and demand for electric vehicles has been increasing globally.
- However, due to the limitations of the current technology, the position of the receiver pad and the transmitter pad caused a few issues to the existing wireless charging systems: (1) larger transmission distance, (2) low magnetic coupling coefficient, (3) low energy efficiency, and significant magnetic flux leakage; (4) human and pet exposure to magnetic field and (5) heating of foreign objects.
- Electric vehicles charging system market is expected to garner $8.02 billion by 2022, registering a CAGR of 30.7% during the forecast period 2016-2022.1

Key Advantages of the Technology
- This technology [IP00705] enables a more efficient way to position the receiver pad and the transmitter pad which results in:
- eliminating all existing issues including misalignment, human exposure to magnetic field, damaged by dirt and dust from the ground... etc.;
- reducing the transmission distance which result in higher magnetic coefficient and energy efficiency; and
- allowing access for monitoring and maintaining of the pads
- Providing water-proof and electrically-insulated surface
- This technology also elevates two existing wireless power transfer Patents under the same inventor, namely the “Methods for Parameter Identification, Load Monitoring and Output Power Control in Wireless Power Transfer Systems”1 and the “Fast Method for Identifying Coil Misalignment/Mutual Coupling in Wireless Charging Systems”2
