  Electric dipole moments (EDMs) of charged leptons arise from a new source of
CP violation in the lepton sector. In this paper, we calculate the EDMs of the
charged leptons in the minimal scotogenic model with two singlet fermions, and
the models extended with one or two triplet fermions instead of the singlet
fermions, taking into account the constraints of the neutrino oscillation data,
the charged lepton flavor violation and perturbative unitarity bound for the
Yukawa couplings. We show that the hybrid model with one singlet and one
triplet fermions predicts an electron EDM larger than the other models in both
normal and inverted neutrino mass hierarchy. We find some parameter space has
already been ruled out by the current upper bound of the electron EDM and
further parameter space can be explored by future experiments.
