本考案は、乾電池など有限寿命の電源を用いて
動作する機器を特性を測定評価するための電池シ
ミユレータに関するものである。[Detailed Description of the Invention] The present invention relates to a battery simulator for measuring and evaluating the characteristics of equipment that operates using a power source with a finite life such as a dry cell battery.

の接続にも手間がかかりきわめて不便である。 Until now, when testing the operation of battery-powered equipment, etc., a DC voltage was temporarily connected to the battery terminal of the equipment using a conductor from a desktop power supply. This conventional method requires the use of a large AC power source, which is extremely inconvenient as it requires time and effort to connect to the machine.

するものである。 The present invention was devised to solve these conventional problems, and provides a battery simulator that can easily perform operation tests on battery-powered devices.
以下本考案の一実施例を説明する。 An embodiment of the present invention will be described below.

を短時間で再現することができる。 Fig. 1 shows the external shape of a simulator according to an embodiment of the present invention.This battery has a positive terminal 2 and a negative terminal 3 in a case 1 having approximately the same external shape as a conventional battery. A power supply device as shown in FIG. 2 is housed inside a shaped case 1. In FIG. 2, 4 is a battery for power supply, and 10 is a switch. 7
is an operational amplifier, one input terminal of which is connected to the connection point between the capacitor 8 and the resistor 9. A resistor 13 is connected in parallel to the capacitor 8. Also,
The connection point between the capacitor 8 and the resistor 13 is connected to the connection point between the resistor 11 and the resistor 12. If a CR composite circuit is used in the input voltage section to the operational amplifier 7 in this way, a power supply can be created in which the output voltage gradually decreases as the switch is turned on, and the life of the battery can be reproduced in a short time.
ここでスイツチ１０が投入されると、抵抗１１
と抵抗１２で分割される電圧V1がオペアンプ７
の入力端子に印加され、この電圧はコンデンサ８
の充電によつて次第に低下してついにはV1を抵
抗１３と抵抗９で分割される電圧V2に至つて定
常化する。抵抗１３を省略するとオペアンプ７の
入力電圧はV2で落着かずゼロにまで至る。これ
を第３図に示す。第３図は縦軸が正端子電圧、横
軸がスイツチ投入よりの時間を表す。第３図の
V1を当該電池の初期端子電圧に、V2を最終寿命
端子電圧に設定すれば、当初の出力電圧が当該電
池の初期端子電圧に近く最終出力電圧が当該電池
の最終寿命端子に近い電池シミユレータを形成す
ることができる。 When the switch 10 is turned on here, the resistor 11
The voltage V 1 divided by the resistor 12 is the voltage V 1 divided by the resistor 12
is applied to the input terminal of capacitor 8, and this voltage is applied to the input terminal of capacitor 8.
As the voltage is charged, the voltage gradually decreases, and finally V 1 reaches the voltage V 2 divided by the resistor 13 and the resistor 9, and becomes steady. If the resistor 13 is omitted, the input voltage of the operational amplifier 7 will not settle at V2 and will reach zero. This is shown in FIG. In FIG. 3, the vertical axis represents the positive terminal voltage, and the horizontal axis represents the time since the switch was turned on. Figure 3
If V 1 is set to the initial terminal voltage of the battery, and V 2 is set to the final terminal voltage of the battery, the initial output voltage is close to the initial terminal voltage of the battery and the final output voltage is close to the final terminal voltage of the battery. can be formed.
第２図による電池シミユレータは、現実の電池
の減衰特性を現出させうるので一定時間中に現実
電池使用時のシミユレーシヨン動作をさせること

通常その経過時間が長すぎて現実の実験、試験な
どでは非能率であることが多い。また現実の電池

とができない。さらに現実の電池を用いると実

のコストは大で、資源の浪費となる。 Since the battery simulator shown in FIG. 2 can exhibit the attenuation characteristics of an actual battery, it is possible to simulate the use of an actual battery during a certain period of time. When operating characteristics are measured using an actual battery, the elapsed time is usually too long, which often results in inefficiency in actual experiments and tests. Furthermore, if an actual battery is used as is, it often leaks into the battery case during decay, making it impossible to use it safely in experiments and tests. Furthermore, if an actual battery is used, the battery must be replaced each time an experiment or test is performed, resulting in a large cost and a waste of resources.
