We show that spatially homogeneous and isotropic evolution of a macroscopic Coulomb system of identical particles with or without uniform background of opposite charge obeys equations that have the structure of cosmological equations of the general relativity theory. Specifically, there is a Hubble law, and the background charge mimics effect of a cosmological constant. Resulting analog cosmologies, relevant to Coulomb explosions and breathing modes in conductors, differ from their gravitational counterparts as the evolution is driven by Coulomb repulsions between the particles.
