Abstract
Power is managed in an elevator system including an elevator hoist motor (), a primary power supply (), and an electrical energy storage (EES) system (). A power demand of the elevator hoist motor is determined, and a state-of-charge (SOC) of the EES system is determined. Power exchanged between the hoist motor, the primary power supply, and the EES system is controlled based on the power demand of the hoist motor and the SOC of the EES system.
