Accompanying drawing explanation
Fig. 1 is embodiment schematic diagram of the present utility model.
The realization of this utility model purpose, functional characteristics and advantage will in conjunction with the embodiments, are described further referring to the drawings.
Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this Utility model.
With reference to Fig. 1, proposing an embodiment of the present utility model, a kind of new type solar energy plate postpones overcharge protection circuit, The solar panels power end 2 being connected with described rechargeable battery 1 including rechargeable battery 1, described rechargeable battery 1 with described too Sun can be provided with time delay overcharge protection circuit 3 between plate power end 2.
Described time delay overcharge protection circuit 3 includes the first resistance R1, the first audion Q1, the second resistance R2, the 3rd resistance R3, the 4th resistance R4, the 5th resistance R5, the second audion Q2, the 3rd audion Q3, unilateral diode D1, Zener diode Z1, First charging capacitor C1 and the second charging capacitor C2, the positive pole VCC of described solar panels power end 2 are connected to described one or three pole On the emitter stage of pipe Q1, the colelctor electrode of described first audion Q1 is connected on the positive pole of rechargeable battery 1, described first audion The base stage of Q1 is connected on the colelctor electrode of the 3rd audion Q3 by the 5th resistance R5, and the emitter stage of described 3rd audion Q3 connects Ground, the base stage of described 3rd audion Q3 is connected on the colelctor electrode of described second audion Q2, described second audion Q2's Colelctor electrode is connected on the positive pole VCC of described solar panels power end 2 by the 3rd resistance R3, and described second audion Q2 sends out Emitter grounding, the base stage of described second audion Q2 is by ground connection after the second resistance R2 and the 4th resistance R4 series circuit, described One end of first resistance R1, unilateral diode D1 and Zener diode Z1 series connection and the first resistance R1 is connected to solar panels power supply The positive pole VCC other end of end 2 is connected on the negative pole of unilateral diode D1, and the positive pole of described Zener diode Z1 is connected to unidirectional On the negative pole of diode D1, the negative pole of Zener diode Z1 be connected on the junction point of the second resistance R2 and the 4th resistance R4, institute State the first charged electrical electric capacity C1 and the second charging capacitor C2 to be in parallel and positive pole is connected on the positive pole of unilateral diode D1, negative pole Ground connection.
Described first audion is PNP type triode.
Described second audion and the 3rd audion are NPN type triode.
Its operation principle is summarized as follows: during solar panels output no-load, voltage is higher, charges the battery wink when receiving VCC Between, VCC first passes through R1 and charges to electrochemical capacitor C1, C2, and voltage is slowly risen by low, and making stabilivolt start moment cannot lead at once Logical, audion Q2 ends, and provides base current turn-on transistor Q3 by R3 simultaneously, and now audion Q1 simultaneously turns on and passes through Battery is charged by audion Q1, and solar panels voltage instantaneous is pulled down to close to cell voltage.
