1. An apparatus, comprising:
an energy storage circuit structured to receive information regarding a state of charge (SOC) and a state of health (SOH) of an energy storage device structured to store energy;
an input circuit structured to receive an indication of a torque demand; and
a hybrid management circuit structured to:
determine a SOH adjustment factor by comparing the SOH of the energy storage device to a predefined SOH trajectory for the energy storage device;
determine a first torque output for a genset based on the SOH adjustment factor and the SOC of the energy storage device, the genset including an engine and a first motor-generator; and
operate the genset to provide the first torque output and to generate an amount of energy for a second motor-generator to meet the torque demand according to the SOH adjustment factor.
