Research on Control Strategy of Working Mode Selection of Bidirectional Charge Piles in Multi-State

Abstract

This paper focuses on the duality of electric vehicle battery "charge-source", proposes a control strategy of bidirectional charge piles in multi-state, to control bidirectional flow of energy between electric vehicle and micro grid. The strategy will preferentially select the operating mode input by the user. Otherwise, the charging or discharging operating mode will be automatically selected according to the SOC of the electric vehicle, the current grid operating status and the current electricity price, the method in this paper is verified by the comparison between the calculated and experimental results.
