The principle of the circuit The mine charging indicator is composed of the electrical resistor R1-R5, the fuse FU, the circuit is as shown in figure 8-36. When the storage battery is charging, the V conducts, the VL2 turns on. When the storage battery is full, the V cuts off, the VL2 turns off. When the polarity connection of the storage battery is correct, the VL3 will not light. If the polarity connection of the storage battery is reverse, the VL will turn on to send out the yellow alarm signal. Components selection The R1-R4 use the 1/4W metal film resistor; R5 use the 2W wirewound resistor.The VD uses the 1N4007 rectifier diode.The VL1-VL3 use the φ5mm high-brightness light-emitting diode.The V uses the S8050 silicon NPN transistor.
