5、 of charge at a high level.in 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 neces

6、sary,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 counter

7、weight to inhibit unnecessary power consumption during the operation of hybrid elevator has been developed.such 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

8、 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.the following method is proposed as a method for controlling an automatic landing device of the elevator.patent document 1,for example,disc

14、terruptible power source returns ,and the rescue operation is conducted upon completion of the charging,the elevator cannot be carried to the nearest floor to perform rescue operation in the case of an abnormal situation of the interruptible power source.as a result,the passengers remain trapped in

15、the elevator. moreover,when the interruptible power source is stopped due to disaster like as in the hybrid elevator,it is necessary for the backup power source to ensure the minimum power supply capacity for enabling minimum operation.consequently,because a margin becomes necessary in the capacity

16、of the backup power source,a large power accumulator is necessary. in addition,the minimum voltage used for calculating the power supply capacity has a margin,in view of the life property.therefore, the value of the actual power supply capacity is smaller than the that of the primary power supply ca

20、he power unit when the power unit is stopped,and a controller for controlling power supply from the power accumulator to a load service;wherein the controller sets an operable voltage,which is determined as an output voltage foe ending discharge of the power accumulator,at a first voltage when the p

21、ower unit is operated,and sets the operable voltage at a second voltage lower than the first voltage when the power unit is stopped ,thereby increasing the power supplied to the load device by the power accumulator. according to the power source system described above,the power supply capacity of th

22、e power accumulator can be improved by reducing the operable voltage of the power accumulator when the power unit is stopped,the operable voltage being set during the normal operation of the power unit.furthermore,because the operable voltage of the power accumulator is reduced after the power unit

23、is stopped,and the number of the times that the power accumulator is over-discharged duo to the decrease in the operable voltage can be prevented from increasing.,the life duration of the power accumulator can be increased.in addition,the size of the power accumulator can be reduced because it is no

40、会代替商业供应电源持续进行供电。举一种备用电源的例子，不间断电源。通过即时切换商业电力源输出的备用电源，在停电的情况下，计算机或存储单元中的应用，以及网络服务设备、如一个服务器无法停止，依靠立即停止商业供电采用备用电源作为电源供应。 这种备份电源结合动力蓄电池剩余容量代表控制保持处于较高的水平充电状态，。在这个系统中，因为一般的剩余电量充电的蓄电池高效的发电电动机的作用，充放电进行控制，使系统不超过100%。为了必要时给电机提供电源，充电放电控制执行以此使系统芯片的电量不减少到零。具体来说，通常在动力蓄电池正常工作时，充放电控制执行是为了使系统芯片的电量波动范围在20%至80%以内.关于电梯，

41、另一方面，一个混合型电梯设备，笼和配重抑制不必要的功率消耗的运作过程中的混合电梯已经发展起来.这种混合电梯设备利用电力的电池在停电时，因此，在停电的情况下或其他异常状态经营的混合动力驱动的电梯，电梯是提供从功率源进行电梯到最近的地板或地板和安全地检索通道从笼。下面提出来能控制能自动升降的电力设备的一种方法，专利文件。1，例如，公开一种对输出电压、输出电流进行检测的方法，电池电源的温度进行救援供应行动以此响应供电能力的电池电源。这里，作为一种计算电源电池储电容量的一种方法，一种可以根据电源电池的开放电压、内部电阻、最小电压计算电源电池储电容量的方法。下面的公式（1）时计算电源电池储电容的，通常被

42、熟知。对电池电源来说，当其被置于一种特定的状态时最小电压是用来估算算电源电池储电容量的。 电源电池储电容量=最小电压*（开放电压-最小电压）|内部电阻 （1）另外，这种混合型电梯必须保证在商业供应电源运行电梯到达某个楼层时如若这时出现紧急情况的情况保证绝对的安全，为了满足安全性，因此，需要一种大容量的动力蓄电池。在公开的专利1提出来的这种方法中，输出电压和设定电压值通过放电时间和放电状态相互限制彼此控制电梯的正常运行。因此，当电源电池的储电容量过低时，电池的储电容量将会丢失，进而阻止电池供电。在这种情况下，由于电源电池不在进行供电信号返回时电池才会进行充电，而且当充电完成后才能进行救援工作，所

43、以说，当不间断电源出现异常情况不能供电时电梯是不能继续运行到最近楼层的。这样的结果就是乘客仍然被困在电梯里面。此外，当不间断电源因为某些事故例如上述混合型电梯里的事故停止供电时，对于备用电源来说保证能提供正常工作状态的最低储电容量是必须的。结果就是，因为备用电源的最小极限储电容量是必须的，所以一个大容量的电源电池的产生是必然的。另外，对生活中的一切物体来说，用来计算电池容量的最小电压必须有个极限。因此，实际上用到的电池容量的价值比最初的动力蓄电池的电池容量小得多。发明的公开。当前发明这种电池的一个目的就是提供能满足备用电源工作最低电池容量、提高动力蓄电池的持续工作时间、通过暂时提高当不间断电源

44、发生类似上述事故不能继续供应电源时动力蓄电池的电池容量来减小动力蓄电池的形状大小的一种电源系统。这项发明同时也提供了一种电池控制电源系统的方法，一种电池控制电池系统程序的方法，并且一个计算机的可读记录媒介使电源随即控制电源电池已经刻录好的程序。根据这项发明的一个方面一个电源系统应该具有：给一负载装置供电的电源单元；当电源单元不能供应时能够代替电源单元供电的一个动力蓄电池；一个控制动力蓄电池给负载装置供应电源的控制器；当控制器被设置一个作为结束动力蓄电池放电的输出电压的工作电压时，如果电源单元正常运行将会被设为一级电压，当电源单元不工作时将会把工作电压设置为比一级电压小很多的二级电压。因此需要通过动力蓄电池来提高电源对负载的供应。根据上述描述的电源系统，动力蓄电池的电池容量可以通过降低当电源单元不工作时动力蓄电池的工作电压来
