System and method for creating a graphical program that uses multiple models of computation. The nickel-metal hydride battery module preferably has a peak power density in relation to energy density as defined by:P>1,375\u221215E,where P is greater than 600 Wattskilogram, where P is the peak power density as measured in Wattskilogram and E is the energy density as measured in Watt-hourskilogram. The voice portal server identifies through a voice recognition algorithm a destination location corresponding to a requested location verbally input by the vehicle occupant.
