An objective of the present invention is to obtain an elevator regenerative power accumulation control device and regenerative power accumulation control method whereby a cell with a maximum capacitance decline rate is prevented from entering a sustained overvoltage state, and it is possible to prevent cell degradation from being accelerated and a replacement period of a capacitor-type accumulation unit from being quickened. A charge-discharge control unit administers a total voltage value of a capacitor-type accumulation unit by a total voltage detection unit. When an overvoltage signal is received from an overvoltage detection circuit, the charge-discharge control unit interrupts charging of the capacitor-type accumulation unit, discharges the capacitor-type accumulation unit to a voltage whereat the overvoltage signal is not outputted, and changes a chargeable total voltage upper bound value of the capacitor-type accumulation unit to a voltage whereat the overvoltage signal is not outputted.
