断状態にある。 In this case, since the proportional voltage of the contact 6 of the resistive voltage divider circuit 5 is low, the base voltage of the first transistor Q1 is low and the first transistor is cut off. Therefore, since the collector of the first transistor Q1 is high, the second transistor Q2 is conductive and the collector of the first transistor Q1 is high.
Bypassing the gate signal of 2SCRS 2 , the second SCR is in a cut-off state.

おり、第２発光ダイオードL2は消灯している。 At this time, the charging current of the battery is large, as shown in 1 in the characteristics of FIG. 2, and the battery B is rapidly charged. Further, since the voltage at the connection point 8 is larger than the constant voltage VZ1 of the first constant voltage element Z1 as shown in 1 in the characteristics of FIG. 2 , the first constant voltage element becomes conductive and the first light emitting diode L1 lights up. It emits a red light to indicate that fast charging is in progress. On the other hand, due to the conduction of the first SCRS 1 , the voltage at the output terminal 2 is lower than the constant voltage V Z2 of the second constant voltage element Z2 , as shown in 1 in the characteristics of FIG. is cut off, and the second light emitting diode L2 is off.

以後は次第に赤色光が弱くなると共に緑色光が強
くなり、橙色光から充電末期には緑色光に変る。 As the charging time progresses, the battery B is charged, and when a predetermined charging voltage is reached at time t, the first transistor Q1 becomes conductive due to the proportional voltage of the contact 6 corresponding to the voltage. Therefore, the collector voltage, that is, the base voltage of the second transistor Q2 decreases, and the second transistor is cut off. Therefore, the collector voltage of the second transistor increases, and this voltage becomes the gate signal.
The 2nd SCRS 2 is turned on, the gate signal of the 1st SCRS 1 is passed through the 2nd SCRS 2 , and the 1st SCRS 1 is cut off to terminate the rapid charging of the battery B. After time t, when the battery voltage drops below the predetermined charging voltage due to the interruption of the first SCRS 1 , so-called jogging charging occurs, in which charging and non-charging periods are repeated, and the non-charging period gradually becomes longer, so the average charging current changes to characteristic 2. It decreases as shown in . In this case, the non-charging period, that is, the conduction period of the second SCRS 2 gradually becomes longer, so the average voltage at the connection point 8 gradually decreases as shown in characteristic 2 , while the average voltage at the output terminal 2
It rises as shown in 2 . Therefore, after time t, the period during which the voltage at the connection point 8 is higher than the constant voltage V Z1 of the first constant voltage element Z1 gradually becomes shorter.
The period during which the first light emitting diode L1 emits red light becomes gradually shorter. Conversely, the voltage at output terminal 2 is
The period during which the constant voltage element Z 2 is higher than the constant voltage V Z2 gradually becomes longer, and the period during which the second light emitting diode L 2 emits green light gradually becomes longer. Therefore, time t
After that, the red light gradually becomes weaker and the green light becomes stronger, changing from orange light to green light at the end of charging.
