电压显示方法、电压显示装置以及组电池
摘要：
本发明提供一种无论显示电压高低的操作时间的长短，操作后的显示时间都固定的电压显示方法、电压显示装置以及组电池。为此，在一端连接于二次电池的电阻器(51)的另一端、和一端经由电阻器(54)连接于电容器55的开关(53)的另一端上连接有电容器(52)，在开关(53)断开的期间，预先从二次电池经由电阻器(51)向着电池电压对电容器(55)进行充电。在开关(53)接通的情况下，电容器(55)以及电容器(52)并联连接，从而电容器(55)的端子电压在短时间内上升。并且，在开关(53)断开的情况下，在电容器(55)的端子电压根据电容器(55)、和电阻器(71、72)的串联电路之间的并联电路的时间常数而持续下降期间，也在显示器(82、85)上进行与该端子电压相应的显示。
摘要（英）：

One terminal of a switch (53) is connected to a resistor (51) having its other terminal connected to a rechargeable battery, and the other terminals connected through a resistor (54) to a capacitor (55). Another capacitor (52) is connected to the node between the switch (53) and the resistor (51). Initially, while the switch 53 is in the OFF state, the rechargeable battery charges the capacitor (52) towards the battery voltage through the resistor (51). When the switch (53) is turned ON, capacitor (55) and capacitor (52) become connected in parallel and the voltage across capacitor (55) rises within a short time period. When the switch (53) again turns OFF, voltage indication continues in compliance with the voltage across the capacitor (55) even as that voltage decays according to the time constant of the parallel circuit formed by the capacitor (55) and a series-connection of resistors (71, 72).
