Fig. 2 is the circuit theory diagrams of an embodiment of the present invention.
Embodiment
Reference picture 1, a kind of battery low-voltage control protective unit, including housing 1, voltmeter 2,3, closing of releasing the button
Button 4, positive input terminal 5, negative input terminal 6, positive output terminals 7, negative output terminals 8 and control board 9, shell
Body 1 is to be made from a material that be electrically non-conductive box typed structure empty in rectangle.Voltmeter 2 is provided among plate top above housing 1, electricity
The bottom of pressure table 2 is provided with release the button 3 and X button 4, and a sidepiece of housing 1 is provided with positive input terminal 5 and negative input
Son 6, the other side of housing 1 are provided with positive output terminals 7 and negative output terminals 8, are provided with housing 1 and voltmeter 2, unlatching
Button 3, X button 4, positive input terminal 55, negative input terminal 6, positive output terminals 7 and negative output terminals 8 are electrically connected
The control board 9 connect.
Reference picture 2, control board is by first resistor that voltage stabilizing value is 9.1V voltage-regulator diode DW, 470-510 Ω
R1,100-200 Ω second resistance R2,1-3K Ω 3rd resistor R3, the first triode T1 of model 9014, model
8050 the second triode T2, relay J and model 1N4001 diode D compositions, relay J are touched with 4123 or T73 etc.
Point electric current is more than 5A miniature electro-magnetic relay, positive input terminal 5 and relay J one end, diode D negative pole with and after
Appliance contact J-1 one end is connected, the J-1 other ends of relay contact and first resistor R1 one end, voltage-regulator diode DW
Negative pole, voltmeter 2 positive pole and positive output terminals 7 be connected, voltage-regulator diode DW positive pole by second resistance R2 with
The base stage of 3rd resistor R3 one end, one end of X button 4 and the first triode T1 is connected, the first triode T1 current collection
Pole is connected with the first resistor R1 other end, and the first triode T1 emitter stage is connected with the second triode T2 base stage,
Second triode T2 colelctor electrode and the relay J other end, diode D positive pole and 3 one end of releasing the button are connected, and bear
Pole input terminal 6 and 3rd resistor the R3 other end, release the button 3 the other end, the other end of X button 4, the two or three pole
Pipe T2 emitter stage, the negative pole of voltmeter 2 and negative output terminals 8 are connected.The voltage-regulator diode.Voltmeter is pointer
Formula voltmeter, from 91L16,20V voltmeter head.When battery is 12V, voltage-regulator diode DW requires that voltage stabilizing value is 9.1V, no
Then overdischarge voltage by be not design load 10.8V.
