Safety and Reliability of Wireless Charging System for Electric Vehicles Based on the Yunnan Power Grid

Abstract:

Electric cars are emerged as the energy crisis and environmental problems have become more severe. Electric vehicles charging include contact and non-contact. The battery technology has not been solved absolutely for Contactless charging, in addition, charging pile construction will take up a lot of urban land, normal charge is slow, fast charge will have a huge impact to grid, the high cost of change the batteries, these drawbacks of electric vehicles has been hampered the large-scale development of EV. With the development and gradual improvement of wireless power transmission technology .wireless charging technology applied to electric vehicles has great prospects. In the wireless power charging process safe, reliable transmission is very important. In this paper, security and reliability problems have been discussed for the various aspects of wireless charging systems and combined analysis of the characteristics of Yunnan Power Grid for wireless charging systems of electric vehicles.
