  We obtain cosmological solutions with Kasner-like asymptotics in N=2 gauged
and ungauged supergravity by maximal analytic continuation of planar versions
of non-extremal black hole solutions. Initially, we construct static solutions
with planar symmetry by solving the time-reduced field equations. Upon lifting
back to four dimensions, the resulting static regions are incomplete and
bounded by a curvature singularity on one side and a Killing horizon on the
other. Analytic continuation reveals the existence of dynamic patches in the
past and future, with Kasner-like asymptotics. For the ungauged STU-model, our
solutions contain previously known solutions with the same conformal diagram as
a subset. We find explicit lifts to five, six, ten and eleven dimensions which
show that in the extremal limit, the underlying brane configuration is the same
as for STU black holes. The extremal limit of the six-dimensional lift is shown
to be BPS for special choices of the integration constants. We argue that there
is a universal correspondence between spherically symmetric black hole
solutions and planar cosmological solutions which can be illustrated using the
Reissner-Nordstr\"om solution of Einstein-Maxwell theory.
