Abstract:
An apparatus includes an energy storage circuit, an input circuit, and a hybrid management circuit. The energy storage circuit is structured to receive a state of charge (SOC) and a state of health (SOH) of an energy storage device. The input circuit is structured to receive an indication of a torque demand. The hybrid management circuit is structured to determine a first torque output for a genset including an engine and a first motor-generator based on the torque demand and the SOC of the energy storage device; determine an adjustment factor based on the SOH of the energy storage device; determine an adjusted torque output for the genset based on the adjustment factor and the first torque output; operate the genset to provide the adjusted torque output and to generate an amount of energy; and operate a second motor-generator at a second torque output to meet the torque demand.
