Elevator control apparatus using charge/discharge control circuit for power storage apparatus

Abstract

To reduce a total power amount required to drive an elevator by a commercial power supply during a peak power-consumption time period, for instance, afternoon in summer time, a control apparatus for this elevator is arranged by employing: a converter for rectifying AC electric power to be converted into DC electric power; and inverter for inverting the DC electric power into AC electric power having a variable voltage and a variable frequency; a motor driven by said AC electric power having the variable voltage and the variable frequency so as to operate an elevator; a power storage apparatus for charging thereinto electric power; and charge/discharge control means for controlling charging/discharging operation with respect to the power storage apparatus based upon a charging target value every time with respect to the power storage apparatus.
