PROBLEM TO BE SOLVED: To obtain an elevator control device capable of extending the life of a power storage device and having high reliability.SOLUTION: If a motor 1 is in a regenerative operation state, a control circuit 20 calculates chargeable electric energy Pp of a power storage device 10 and a predicted regenerative electric energy Pr predicted to be generated by the next stop position of an elevator car. If the predicted regenerative electric energy Pr exceeds the chargeable electric energy Pp, a value of a current flowing through the power storage device 10 is controlled so that a charge amount of the power storage device 10 reaches a full charge amount by the next stop position. Furthermore, if the predicted regenerative electric energy Pr is equal to or lower than the chargeable electric energy Pp, a voltage of a bus line 3 is set so as to increase the regenerative electricity of the motor 1. |
