Qijun Deng received the B.S and M.Sc. degrees in mechanical engineering from Wuhan University, Wuhan, China, in 1999 and 2002, respectively, and the Ph.D. degree in computer application technology from Wuhan University, Wuhan, China, in 2005.

In June 2005, he joined the Department of Automation, Wuhan University, where he is currently an Professor. From 2013 to 2014, he was a visiting scholar at New York University Tandon School of Engineering.   Prof. Qijun Deng has authored or co-authored over 30 journals and conference papers, and over 14 patterns. His research interests include wireless power transfer, distribution automation, and electrical power informatization.

     Prof. Deng and his research group conduct comprehensive researches on the field of inductive power transfer system. During the last five years, his group has been awarded 6 projects involved the field of inductive power transfer  with the total money over 5 million Chinese Yuan. Funded by these projects, many academic results have been achieved.  Under the funding of the NSFC project titled "modeling and quality factor optimization of non-idea Litz coils for a wireless power transfer system",  a finite element model has been developed to evaluate the current distribution among two thousands of strands composing the Litz-wire at high frequencies. A current-balance theory is being developed to distribute current evenly among these strands to achieve lower AC loss.

   Beside academic outcomes, many industrial prototype have been developed. They have designed wireless chargers for EVs with 3 power levels, name 1.5kW, 10kW and 25kW. The efficiencies of these prototype are up to  94%. Funded by the project of "wireless supply for monitoring instruments in smart grid " awarded by China Southern Grid Corp, prototypes with various sending-receiving distances from 0.5 meter to 3 meters are developed.  A power up to 10 W can be received at the distance of 3 meters. In the year of 2015, 10 inductive power transfer sets are installed in the 35 kV transmission lines which harvest power from the lines and send the power wirelessly to the power tower to drive monitoring instruments including cameras. Recently, an inductive charger together with multiple relay chargers have been employed successfully to supply power for wireless sensors network.
