Method of battery adjustment for hybrid drive by modeling and simulation

Battery modeling and simulation are most useful for designing storage unit for hybrid drives. The background of battery modeling is to determine electromotive force (EMF) in dynamic way (non-measurement) and internal resistance as the function of state of charge (SOQ). This paper presents how to use battery modeling for simulation in hybrid drives and select the proper operating range of battery SOC according to simulation results. The target of simulation is to compare the performance of different types of battery and to find optimal parameters (battery mass, capacity and voltage) of battery pack for hybrid drive system. The simulation is based on the target function of minimum energy consumption (fuel and electricity).
