The course of work as shown in Figure 7, in the time that charge power supply is opened, the first light emitting diode lamp D1 conducting glows, because the resistance of the 3rd resistance R 3 is far longer than the conduction impedance of the first light emitting diode lamp D1, so the second light emitting diode lamp D2 is not luminous.When charge power supply is turn-offed, the energy storage devices such as electrokinetic cell have small electric current to flow through charging indicator light circuit by charging circuit, but not enough so that the first light emitting diode lamp D1 conducting, the first light emitting diode lamp D1 is not luminous, because the resistance of the 3rd resistance R 3 is now much smaller than the shutoff impedance of the first light emitting diode lamp D1, therefore this Weak current mainly flows through from the 3rd resistance R 3 and the second light emitting diode lamp D2, because the second light emitting diode lamp D2 conduction impedance is less, therefore, the second light emitting diode lamp D2 conducting, send green glow, remind related personnel to charge.
As shown in Figure 8, be two of the indicator light circuit schematic diagram of the charging gun of embodiment.By choosing the first suitable resistance R 1 and the second resistance R 2 is carried out dividing potential drop, making the voltage that a is ordered is 5V high level.Simultaneously by the curent change in Sensor monitoring charging process.At the charging initial stage, charging current is larger, by transducer, b point is provided to a low level, and because a point is high level, now red the first light emitting diode lamp D1 lights, and green the second light emitting diode lamp D2 does not light, to show that charging carries out.In the time that charging completes, electric current diminishes, now by the variation of Sensor monitoring electric current, b point is provided to a high level, and because a point is high level, now red the first light emitting diode lamp D1 extinguishes, green the second light emitting diode lamp D2 lights, saturated to show charging.
The first light emitting diode lamp D1 is red light emitting diodes; The second light emitting diode lamp D2 is green LED; Form charging indicator light electric current by the first light emitting diode lamp D1, the second light emitting diode lamp D2, the 3rd resistance R 3 and the 4th resistance R 4.The 3rd resistance R 3 and the 4th resistance R 4 are current-limiting resistance, avoid electric current excessive.
