Wireless charging electric vehicles (EV) is the development trend of EV. However, the battery taken by EVs has the disadvantages of big volume, long time to recharge, and limited driving distance. In this paper, an innovative dynamic wireless charging system based on magnetic coupled resonant power transmission is presented. The transmitting coil of this charging system can selectively turn ON/OFF...
With breakthroughs in battery technology, plug-in hybrid electric vehicles (PHEVs), jointly powered by an electric drive and an internal combustion engine are becoming a realistic alternative. In a PHEV, the battery is charged by the grid and the electric machine plays the major role in the vehicle drive so that the engine is only required to provide extra torque when accelerating and to drive the...
This paper studies a wind-solar complementary single-phase sine wave power inverter, including the hardware structure, operating principle, and method to the charging and discharging design. A dual-level three-state intelligent float charging based on PIC single chip control is brought forward for combining the special characteristics of wind-solar energy system. It helps the automatic transfer between...
Much attention has been paid to electric vehicles recently due to environmental concerns. The plug-in hybrid electric vehicle (PHEV) consisting of both electricity storage and gasoline tank is welcome to electric vehicle market. In the PHEV system, the electric machine drive is one of the key issues. The ideal tendency is to use the drive machine over the entire torque/speed range with high starting...
