A brane evolving in the background of a charged AdS black hole displays in general a bouncing behavior with a smooth transition from a contracting to an expanding phase. We examine in detail the conditions and consequences of this behavior in various cases. For a cosmological-constant-dominated brane, we obtain a singularity-free, inflationary era which is shown to be compatible only with an intermediate-scale fundamental Planck mass. For a radiation-dominated brane, the bouncing behavior can occur only for background-charge values exceeding those allowed for non-extremal black holes. For a matter-dominated brane, the black-hole mass affects the proper volume or the expansion rate of the brane. We also consider the brane evolving in an asymmetric background of two distinct charged AdS black hole spacetimes being bounded by the brane and find that, in the case of an empty critical brane, bouncing behavior occurs only if the black-hole mass difference is smaller than a certain value. The effects of a brane curvature term on the bounce at early and late times are also investigated.
