I dont think there is a charge that has no mass. Light is not considered having a charge, protons and electrons are, and those have mass. Maybe I should have said 'charged particle' but it should be synonymous. Your link unfortunately does not answer the question.

Sorry, brain fart above and I typed the wrong thing: I means that a photon does not have kinetic energy because a photon has no mass.

Hopefully someone with more knowledge can jump in, but I don’t know that there’s an intuitive reason why Planck’s Relation is true. I think it’s a relationship derived from the Schrödinger Equation and Einstein’s work on relativity and then extensively measured and confirmed since then.
