摘要
电动汽车性能的稳定性离不开稳定、高效的充电控制技术。采用恒压充电策略对电动汽车充电系统进行电路设计,所设计的充电控制系统采用零电压移相全桥变换器作为直流变换器,并在控制系统中设计了基于电池组端电压反馈的PID控制方式。通过对设计的系统进行建模、软件仿真,仿真结果证实了设计的控制电路能够在电动汽车蓄电池充电时实现对电压的稳定控制。
The charging control technology is one of the key technologies in the electric vehicles,and the stable and efficient charging is important.Base on the working principle of electric vehicles and the characteristics of the power batteries,the electric vehicle charging circuit system is designed utilized the constant voltage charging strategy.In the designed charging control system,the DC converter is based on the structure of the zero voltage phase shifted full bridge converter.And the PID control method based on battery end voltage feedback is designed in the control system.The theoretical feasibility of the design is confirmed by the simulation of the charging control system mode.The charging voltage can be stably controlled by the design circuit.
