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. Power exchanged between the hoist motor, the primary power supply, and the energy storage system is controlled to address power demand of the hoist motor and to maintain the storage state of the energy storage system at about the target storage state. |
