The short answer
One is a term; the other is a concept with a literature behind it. If you want to read further, search object constancy — it's what emotional permanence is describing, and it has clinical writing going back to Hartmann in 1952 attached to it rather than none.

What each one means
Emotional permanence is an informal, internet-coined term for trusting that someone's care still exists when they're absent, silent, or you're in the middle of a fight — and it is not a research term.
Full definition of Emotional Permanence →In psychoanalysis, the capacity to keep a stable, whole picture of someone — and stay connected to your good feelings about them — when they're absent, disappointing, or you're angry with them. In perceptual psychology the same phrase means something else entirely: seeing an object's size, shape and colour as constant even as distance, angle and light change.
