Extends from BaseClasses.Battery (partial model of a battery).
Information
Extended model for an eletrical battery based on the Kinetic Battery Model (KiBaM) of Manwell and McGowan (J. Manwell, J. McGowan, B.-G. E.I., S. W., and L. A.), Battery capacity varies with current draw, nominal capacity is equal to a 20hrs discharge rate.
