Abstract
A hybrid energy management system that estimates the net regenerative energy that can be collected during the breaking action of the swing mechanism, then, since this is the net energy that can be used to recharge an energy storage device without using the engine to help recharge the energy storage device, the system limits the use of the energy storage device to that net amount predicted to be available from the recovery period. The net regenerative energy is calculated by considering motor and inverter efficiencies for transferring energy to the battery and changes in the boom/stick/bucket inertia moment.
