Batman wouldent win this, Rhino would lose this. Upon charging batman rhino would stumble on a rock or another form of debris. he would then slam his head into a nearby pole which would start a chain reaction.
A car would swerve to avoid hitting rhino and crash into a nearby tanker which would spill open. Gas would fly out of the tanker and the car that struck it would soon catch on fire. As rhino got up to reorient himself the blast would trigger sending rhino flying into a conspicuously but naturally placed spike, rhino would land on it, blood dribbling out of his mouth.
all while batman sits back amazed at the catastrophy, hand at the ready but never really neccessairy.
