Abstract
The more popular of electric vehicles is, the higher the load capacity of the battery is in the power system, therefore, the charging and discharging technology is particularly important. This paper introduces several electric vehicle battery charging methods commonly used at present, describes working principle of the bidirectional DC/DC converter in detail in the battery charging and discharging process, and the bidirectional DC/DC charging and discharging control strategy. Finally, the electric vehicle battery charging and discharging simulation model is built, the validity of the electric vehicle battery charging and discharging model is verified based on control strategies mentioned herein by use of simulation.
