Peak Power Control of Battery and Super-capacitor Energy Systems in Electric Vehicles

摘要: Hybrid energy systems consist of a load powered by source and form storage. Systems with mixed supply find applications in the electric grid renewable non-renewable sources, mission critical such as Mars rovers rechargeable non-rechargeable batteries low-power monitoring harvesting. A general problem for hybrid is reduction peak power consumption to ensure cost-efficient operation draws require additional resources, adversely affect system reliability storage lifetime. Furthermore, some cases vehicles, dynamics are fast, not perfectly known priori computation available often limited, making implementation traditional optimal control difficult. This paper aims develop scheme reduce drawn from limited forecasts. We propose two levels provide sufficient condition different storage/generation components meet instantaneous while satisfying threshold. The provides performance comparable Model Predictive Control, requiring less only coarse-grained predictions. As case study we implement battery-supercapacitor an vehicle real world drive cycles demonstrate low execution time effective battery (hence temperature), which crucial lifetime battery.
