Electric Vehicle Wireless Charger

Overview

The Electric Vehicle Wireless Charger (EVWC) charges electric vehicles (EV) remotely by magnetic resonance. The EVWC transmits electrical energy from transmitter coil on the ground to the receiver coil on th EV chassis with high energy transfer efficiency. This highly efficient and safe EVWC has medium charging power and magnetic flux leakage protection. The charger is designed referencing the SAE J2954 standard on wireless power transfer, being compatible with EVs of Europe, the United States (US), Japan and mainland China.

Problem addressed

In additional to the existing conductive EV chargers, there is a growing demand in wireless EV chargers. Wireless charging is more convenient, sustainable, and it can eliminate the risk of electric shock. There is a huge market for wireless EV chargers as the use of EVs is being promoted all over the world, including Hong Kong, mainland China, Japan, Europe and the US. The development of EV charger can also drive EV promotion.
