Charge Discharge Design of Electric Vehicle Based on Single-Phase Bi-Directional Converter
With the proposing of green transportation,the trend of electric vehicles replacing fuel vehicles is becoming increasingly evi-dent.With the realization of large-scale application,electric vehicles can even act as energy storage devices to compensate for the power grid during peak electricity consumption.In response to the issue of battery charging and discharging in electric vehicles,a single-phase bidirectional converter is taken as the main topology of the charging equipment for electric vehicles,and a control method that combines current closed-loop and midpoint voltage closed-loop is proposed to achieve bidirectional energy flow.The experimental results verify the effectiveness of the charging and discharging scheme for electric vehicles proposed,providing a certain foundation for accelerating the popularization of electric vehicles.
