Specific embodiment
Technical scheme is further illustrated below in conjunction with Figure of description and specific embodiment.It should be appreciated that this
The described specific embodiment in place is only used to explain the present invention, is not intended to limit the present invention.
The present invention proposes a kind of simple battery charge prompting method, it is characterised in that including：Charge prompting circuit（1）、
Controller（2）And battery（3）；The positive pole of current source and charge prompting circuit during charging（1）Middle A points are connected, and negative pole is carried with charging
Show circuit（1）Middle B points are connected.
As the improvement of such scheme, charge prompting circuit（1）In, A points and resistance（R1）One end be connected；Resistance（R1）
The other end and light emitting diode（LED）Anode be connected, light emitting diode（LED）Negative electrode and transistor（Q）Collection
Electrode is connected；Transistor（Q）Emitter stage be connected with B points, transistor（Q）Base stage and resistance（R2）One end phase
Even, resistance（R2）The other end be connected with F points；Photo-coupler（OC）Phototriode be connected in parallel on light emitting diode（LED）On,
And photo-coupler（OC）1 pin and light emitting diode（LED）Anode be connected, 2 pin and light emitting diode（LED）Negative electrode phase
Even, 3 pin are connected with E points, and 4 pin are connected with F points；Diode is used between B points and F points（D）Separate, and diode（D）Anode and F
Point is connected, and negative electrode is connected with B points.
As the improvement of such scheme, controller（2）Control end and charge prompting circuit（1）In E points be connected, control
Device（2）The exportable high level of control end or low level, and output high level when can make photo-coupler（OC）In the pole of hair pipe two
