Renewable energy research has been actively performed nowadays in order to replace the fossil energy, which will be depleted in near future. Hydrogen energy is one of the prominent solutions to be fully utilized in near future. Specially, hydrogen hybrid vehicle is now in the market, and it may be soon the most important transport means within ten years. Therefore, to save hydrogen consumption in the vehicle, more efficient energy usage is compulsory. In this paper, robust control(TDC) technique is designed and applied to the bi-directional DC-DC converter for fast response and more efficient battery charge and discharge. Comparing 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.
