Idea

One A of the odd generators in aconserved charge (under Noether's theorem) of a supersymmetry transformation is called asuper Lie algebrasupercharge.

Equivalently, by Noether's theorem, this is an odd symmetry generators in a supersymmetry super Lie algebra.

Examples

For instance the Dirac operator in supersymmetric quantum mechanics.
