【正文】 the power source system recoded thereon. Background Art In recent years ,a power accumulator has drawn wide attention and been used as backup power backup power source is changed when a mercial power source operated normally,and continues supply power to equipment in place of the mercial power source when mercial power source has a of such a backup power source include a UPS （ Uninterruptive Power Source ） .By instantaneously switching the mercial power source to an output of the backup power source in case of power outage,a puter or a storage unit in use,as well as work equipment such as a server are prevented from being stopped. Such a backup power source bined with the power accumulator is controlled to maintain residual capacity representing the state of charge at a high this system,generally because surplus power is charged in power accumulator efficiently by a power generation action of an electric motor,charge|discharge control is performed so that the SOC does not exceed 100%.In order to supply power to the electric motor when necessary,charge|discharge control is performed so that the SOC does not decrease to 0(zero).Specially,normally in power accumulator,the control is performed so that the SOC fluctuates within a range of 20% to 80%. With regard to elevators,on the other hand,a hybrid elevator that has a cage and a counterweight to inhibit unnecessary power consumption during the operation of hybrid elevator has been a hybrid elevator utilizes the power of its battery at the time of power outage,so that in case of power outage or other abnormal state during of operation of the hybrid elevator,the power for driving the elevator is supplied from a power source to carry the elevator to the nearest floor or any floor and safely retrieve the passage from the stage. 2 The following method is proposed as a method for controlling an automatic landing device of the Document 1,for example,discloses a method for detecting the output voltage ,output current,and a temperature of a battery power source to perform a rescue operation in response to the power supply capacity of the battery power source. Here,as a method for calculating the power supply capacity,a method for calculating the power supply capacity from the open voltage,internal resistance,and minimum voltage(operable voltage) of the battery power source is generally known ,as shown is equation (1) minimum voltage used for calculating the power supply capacity is set with a certain degree of margin,in view of the life of the battery power source . Power Supply Capacity= minimum voltage*(open voltage minimum voltage)\internal resistance.............(1) Moreover,the hybrid elevator has to always secure energy amount for carrying the elevator to a necessary floor in case of emergency during the normal operation of mercial power source ,and thereon a large power accumulator with a large capacity required. In the method disclosed in Patent Document 1,the output voltage
