Beschreibung
Zusammenfassung:	An automotive storage battery charging indication alarm circuit based on an LED belongs to the technical field of light-emitting diode (LED) application. The automotive storage battery charging indication alarm circuit can solve the problem that alarm circuit current is not sufficient in an alarm circuit, with lamp bulbs replaced by the light-emitting diode (LED), of an automotive combination meter. A light-emitting diode PL1 is in serial connection with a resistor R2, then is in parallel connection with a plurality of resistors and finally is in serial connection with a diode RD1, and a negative electrode of the diode RD1 serves as an external port of the alarm circuit. The automotive storage battery charging indication alarm circuit is mainly applied to charging of automotive storage batteries.
