Ever increasing demand for the petroleum is causing faster than expected oil shortages in the supply and demand balance around
the world and furthermore, many specialists in the field of oil production such as Association for the Study of Peak Oil and
World Energy Outlook are claiming that the petroleum is around the peak of its production (Figure 1). Such shortage made the
greatest impact on the gasoline price hikes at the gas pump and thus, this impact was felt by the consumers severely and became
the greatest motivation for automotive industries to strive to pioneer the researches for the next generation vehicle configurations
ranging from HEV, PHEV, Pure EV to FCHEV (collectively noted as xEV). While the great deal of researches has been carried
over the last few decades, it is still far from mass productions for consumer use except for the HEV mainly due to the high
cost involved with other types of xEV configurations. Therefore, it is critical to design the vehicle to maximize the use
of each component at its highest point regardless of any cost scenarios and it is clear that this optimization can only be
achieved through the accurate energy balance simulation for a specific target vehicle prior to the actual hardware implementation.
In this paper, it is our intention to introduce modified dynamic battery modeling scheme that would provide a more accurate
way of simulating the battery behavior when used in the vehicle energy simulation system. Starting from a typical battery
dynamic model to predict the voltage given an imposed current request, we have introduced a new scheme to establish the relationship
between the voltage and the power (rather than the current) requested by the vehicle simulation system. The proposed scheme
handles the power request from the vehicle simulator considering the dynamic battery characteristics and in turn, contributes
to the better estimation of the current integrated energy usage and battery SOC level in the given battery dynamic system
used in the vehicle energy simulation system. 相似文献
