While modelling our late time cosmically accelerated universe, it is popularto involve different dark energy models, the equation of state of which can betaken as a function of the redshift and some unknown parameters. Barboza andAlcaniz have proposed one of a such kind of dark energy's EoS model. We usesome new parametrizations like Feng, Shen, Li, Li I and II and Polynomialparametrizations to get more accurate concepts about the fate of our expandinguniverse. We try to find how the hypothesis of the fate of our universe behavesin the above background of dark energy models. Possibilities of occurrences offuture cosmic singularities are studied.
