| dc.description.abstract | The environmental and economical issues with transportation have accelerated the development of plug-in hybrid electric driven vehicles. Amongst the most prominent techniques for energy storage within this field is the usage of Lithium Ion batteries. Because of this a study requested by ETC Battery and Fuelcells Sweden AB, has been made for investigating the performance of this technique. For this investigation a simulation model was used based on the physical parameters (Internal Resistance and Open Circuit Voltage) of the battery cell. These physical parameters were found through laboratory experiments and simulations methods which were verified through previously performed investigations. The battery cell types investigated in this study were LiFePO4-ePLB F014 with capacity 14.5Ah and LiNiCoMnO2-ePLB C020 with capacity 20Ah, which both are intended for a Plug-in hybrid vehicle. Knowledge about the battery cell performance is needed for the battery system in the plug-in hybrid vehicle in order to determine its State of Charge (SOC) and Power Limits for charge and discharge. SOC is used as a fuel gauge for the battery package, i.e. it provides information on how much energy that is available in the battery. Power limits are important for the vehicle in order to limit the power outage from the battery cell. The simulations showed a good overall accuracy of the battery model. Simulations for studying the State of Charge were also performed and these also showed an acceptable result. Since the accuracy of the model was well within acceptable error limits, the parameters may be used in a plug-in hybrid vehicle. This project will not handle complex technical details of the battery cell, neither environmental nor economical aspects of the battery cell. Comparisons with other battery cells will not be performed nor will the simulation model be explained in detail. | |
