Morphology

rev + up

The sense is directly built from 'rev' (to raise engine speed) combined with 'up' (to increase), so the expression denotes an increase in intensity; the noun 'rev up' is simply a nominalization of that compositional meaning. The metaphorical extension from engine speed to activity or effort is predictable and common in English (and mirrored in other languages), so a B1 learner who knows both constituents would likely infer the meaning.

Etymology

Rev up comes from the image of an engine: to rev (make the engine turn faster) and up (more). Drivers would rev the engine to get power, so rev up now means 'to increase the speed or energy' of something.
