Abstract: Power distribution is managed in an elevator system including an elevator hoist motor (12), a primary power supply (20), and—an energy storage system (32). A predicted usage pattern for the hoist motor is established based on past hoist motor power demand in the elevator system or in similar elevator systems in similar buildings. A target storage state for the energy storage system is then set based on the predicted usage pattern.
