At present the V2G (vehicle to grid) technology is drawing people's attention, which can relieve the problems of low grid efficiency and renewable energy fluctuation, and also bring EV owners profits. In this paper the concept and evaluation of V2G are firstly described, then the implement method is classified according to different objects. The paper reviews the key problems which are referred to by V2G, such as intelligent dispatching and intelligent charging/discharging management, bi-directional charger as well as the effect of V2G on battery, and introduces the research in China. Finally the key technologies are concluded as well as the developing trends, and some advices are given according to the condition of China. THE CONCEPT OF V2GEfficiency of power grid in fact now is not very high, because it is the high cost, and easy to cause waste [1]. One part of the problem is by daily load demand fluctuations and need for power grid voltage and frequency regulation. When the capacity of the power plant needs more than the basic load of power grid, due to the power grid itself is not enough electricity storage, load power plant will be put into operation, sometimes rotating standby involved. And when the grid when demand is low, the output of the power plant power consumption will be lower than the basic load, so that the unused energy will be wasted. In addition, the voltage and frequency regulation of power grid to a great extent, increased the operation cost of power grid. Now, plug-in hybrid electric vehicle (PHEV) and pure electric vehicles (EV) is slowly into the market. Because these cars are equipped with large capacity battery, can consider to allow them to provide the energy for the grid buffer when _____________

Abstract-A three-phase battery charger for electric vehicles is proposed in this paper. The charger is bidirectional, allowing the Charging and Vehicle to Grid operation modes. A novel Balanced Sinusoidal Source Current control strategy is proposed so that the charger demands or injects into the grid a perfect sinusoidal and balanced source current in phase with the positive sequence fundamental component of the phase-toneutral grid voltage, achieving a unity displacement power factor. In this way, the charger turns the car into a smart vehicle, reducing the existing problem of harmonic current demand by electric and hybrid vehicles and improving the power quality of the electric power system. The topology and control stage of the charger are shown. Simulation tests are conducted to validate the proper operation of the charger under sinusoidal, distorted and unbalanced source voltages.

“…As a basic quick charging model, we use the model mentioned in [18] with the specification specified in [16]. To simulate the quick charging of an EV using this model, first, the maximum charging current and voltage are calculated taking into account the specifications of the QC and the battery of the EV, and the maximum charging power set by the SA/PA agent.…”
