Abstract

Most researches on electric vehicles (EVs) regard EVs and their power batteries as a whole, so the attributes of EVs such as their mobility, distributed charging and decision-making are regarded as the attributes of batteries, thus the conception of vehicle to grid (V2G) comes into being and many related challenges appear during the implementation of V2G. By means of decoupling the assets relation of power batteries from EVs and then through the dual decoupling of power service for EVs from charging/discharging of power batteries with/to power grid, it is possible to construct large-scale concentrated energy storage charging station. On this basis, the conception of V2G is expanded to the conception of batteries to grid (V2G), therefore the essence of energy interaction between power batteries and power grid is revealed. The necessity and advancement of the transition from V2G to B2G are expounded, and the challenges in the operation, management and technology that will be faced with during the implementation of B2G as well as possible solution for them are discussed. Finally, the good prospect of adopting B2G technology for smart grids is revealed.
