MOVIKIT^® PowerAndEnergySolutions add-on PredictiveChargeControl

The software module provides the option of changing the state of charge of the energy storage unit based on the potential height energy of hoists in storage/retrieval systems. The positions of the individual lifting axes are offset against each other to reduce or increase the required state of charge of the energy storage unit, based on the expected amount of recuperated energy. A general reserve is kept available for further drives and travel movements. This function is intended to help adapt the state of charge of the energy storage unit specifically to the lifting and travel movements, to save energy, and to reduce the required storage capacity as well as the associated purchase costs of the storage system.

The following figure shows an upward travel movement of the vertical drive followed by a downward travel movement. The state of charge of the energy storage unit is reduced because the lowering movement feeds back a large amount of energy into the energy storage unit.
