Abstract :
Time delay control (TDC) is selected, designed and implemented in the bi-directional DC-DC converter system to supply stable DC link power to the load side. In compared with PID results, TDC can offer better performance in charging the battery or in supplying the required power without significant power loss. NEDC load profile is used to analyze the battery SOC in real-time. LabVIEW system is selected for real experimental device, and Li-ion battery is used for showing the power charging and discharging efficiency.
