Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
See also shown in Figure 1, the utility model is the intelligent solar charge controller of negative pole connection altogether, mainly the direct current by solar panel output is total to the negative pole charging circuit to charge in batteries through tandem type, when the voltage of storage battery reaches float charge voltage by charging, the PIC Single Chip Microcomputer (SCM) system can be judged battery tension, the output control signal is to the negative pole charging circuit shutoff altogether of booster driving circuit control tandem type, and solar panel just stops the charging to storage battery like this; The electric current of storage battery output outputs to load through the field effect transistor T3 that is connected on discharge loop, when the voltage of storage battery hangs down owing to discharging, the PIC Single Chip Microcomputer (SCM) system can be judged battery tension, and the output control signal is turn-offed to booster driving circuit control T3, stops output.
Tandem type of the present utility model negative pole charging circuit is altogether realized the method that charging is controlled: as accompanying drawing 2, two field effect transistor T1, T2 common sources connect (s1s2 point among the figure), common gate driving (g1g2 point among the figure), like this when two field effect transistor T1, T2 conducting simultaneously, tandem type negative pole charging circuit conducting altogether is resistive, can be to charge in batteries; When like this when two field effect transistor T1, T2 turn-off simultaneously, tandem type negative pole charging circuit altogether can be fully by turn-offing.When tandem type altogether during negative pole charging circuit conducting work, because the resistance of field effect transistor is very little, the conventional circuit of diode is arranged with respect to charge circuit like this, heating is still less, efficient is higher.
The method that booster circuit of the present utility model adopts: as accompanying drawing 3, by oscillator signal of single-chip microcomputer output, through T4, T5, the circuit that T6 and R4 form promotes by two diode D1, D2 and two capacitor C 1, the voltage-multiplying circuit that C2 forms boosts, 2 times that produce with booster circuit to the driving voltage VDD of system works voltage VCC, and the control signal of single-chip microcomputer is respectively by R6, R7, the charging drive circuit that T6 forms to tandem type altogether the negative pole charging circuit carry out drive controlling and by R8, R9, T7 forms the discharge drive circuit discharge field effect transistor T3 is carried out drive controlling.
The implementation method of 12V/24V identification of the present utility model and overvoltage, under-voltage protection: as accompanying drawing 4; sampling resistor R1, R2 and potentiometer RW are connected on storage battery the two poles of the earth; by R1, R2, RW battery tension is carried out dividing potential drop; obtain one and the proportional sampled voltage of battery tension; use A/D (mould/number) conversion port of PIC single-chip microcomputer that sampled voltage is sampled; the PIC single-chip microcomputer to adopt data analyze; judge battery tension, handle according to the program of setting then.For example: if judge that by sampling battery tension is greater than 16V, just can judge storage battery is not the 12V specification, because the utility model only uses two kinds of specifications of 12V, 24V, just can judge that current storage battery is the 24V specification, the PIC single-chip microcomputer can make device by the work of 24V pattern according to the program of setting, otherwise be exactly the 12V specification, device can be pressed the work of 12V pattern; If judge that by sampling battery tension is on the low side, the PIC single-chip microcomputer can be controlled field effect transistor T3 according to the program of setting, and T3 is turn-offed stop output, has so just accomplished under-voltage protection; If judge that by sampling battery tension is higher, the PIC single-chip microcomputer can be controlled tandem type that T1, T2 form negative pole charging circuit altogether according to the program of setting, and will stop the charging of storage battery, so just can control the float charge voltage to charge in batteries.
The implementation method of temperature-compensating of the present utility model: temperature sampling of the present utility model is to utilize the different characteristic of thermistor resistance under different temperatures to realize.As accompanying drawing 4, at the two ends of reference voltage source series resistance R3 and thermistor RT, by the voltage sample of the similar battery tension method of sampling to R3 and RT dividing point, the PIC single-chip microcomputer can be judged ambient temperature according to the program of setting, and carries out temperature-compensating according to the temperature of judging then.For example: the PIC single-chip microcomputer is judged the residing operating ambient temperature of storage battery by temperature sampling, is higher than 25 degree Celsius if judge temperature, and the PIC single-chip microcomputer can reduce float charge voltage according to the program that configures; Be lower than 25 degree Celsius if judge temperature, the PIC single-chip microcomputer can be according to the program rising float charge voltage that configures.The utility model can be to the per 1 degree centigrade of compensation 4mV of every battery cell.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
