Zusammenfassung:	An elevator system is provided that includes an elevator car(12), a counterweight(18), a load bearing flexible member , a motor have a drive , and an elevator control system(22). The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit (24) and a power storage device (26). The power storage device includes a supercapacitor unit(32) and a battery unit (34). The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive , and the flow of regenerative power from the motor drive to the power storage device (26).
