Wherein, the central processing unit is communicated with the detecting module, the control module and the DC voltage stabilizing module. The detecting module is connected with an input interface of a solar module to detect voltage of a storage battery and input the voltage into the central processing unit. In addition, the DC voltage stabilizing module is connected with the solar module to convert the voltage output from the solar module into a stable DC voltage through DC-DC conversion and input the voltage into the control module. The control module is connected with the solar module and a load to receive commands of the central processing unit to switch on and off a charging circuit and a power supply circuit and control the solar module to charge and discharge and supply electric power to the load.
Description
Technical field
The utility model relates to the solar-electricity source controller.
Background technology
Existing solar-electricity source controller, the main batteries that plays the protection solar electric power supply system prevents overcharge of a battery and overdischarge.But the solar electric power supply system that uses this quasi-controller mainly by storage battery to electric, and solar cell can not be directly to electric, can only charge to storage battery, when storage battery was full of, controller realized stopping the solar cell short circuit to charge in batteries; When sunray was strong inadequately, the photovoltaic voltage that produces because of solar cell can not cause a large amount of energy wastes to charge in batteries inadequately simultaneously, and economic benefit is low.
The utility model content
The purpose of this utility model is to provide a kind of solar-electricity source controller, and it can prevent overcharge of a battery and overdischarge; During to electric, when the solar cell power output is enough by solar cell directly to electric with to charge in batteries, when the solar cell power output is not enough, replenish power supply to load by battery discharging; When charge in batteries is full of, controller will cut off the charge circuit of solar cell to storage battery, stop charge in batteries, only to electric, rather than the solar cell short circuit be realized stopping to charge in batteries; When sunray was strong inadequately, controller promoted the photovoltaic voltage that solar cell produces, and storage battery is charged again, and improves the utilization ratio of solar energy greatly, increases economic efficiency simultaneously.
A kind of solar-electricity source controller described in the utility model, contain CPU, detection module, DC voltage-stabilizing module and control module, CPU and detection module, control module links to each other, control module also links to each other with the DC voltage-stabilizing module simultaneously, detection module links to each other with the batteries input port, detect battery tension and import CPU, the DC voltage-stabilizing module links to each other with solar battery group, the solar battery group output voltage is converted to a stable DC voltage by DC-DC, be input to control module, control module and batteries, load links to each other, receive the CPU instruction and switch on and off charge circuit and current supply circuit, the control batteries discharges and recharges and to the power supply of load.
CPU detects accumulator battery voltage by detection module, when accumulator battery voltage is too high, stops power supply to batteries by control module, crosses when low at accumulator battery voltage, stops electric by control module control; The DC voltage-stabilizing module links to each other with solar battery group, when the solar battery group overtension, reduces its voltage, promotes its voltage when the solar battery group brownout, by control module to batteries and electric.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is the circuit diagram of a kind of embodiment of the utility model;
Embodiment
A kind of solar-electricity source controller described in the utility model, as Fig. 1, contain CPU, detection module, DC voltage-stabilizing module and control module, CPU links to each other with detection module, control module, detection module is also connecting the storage battery input port, and control module also links to each other with the DC voltage-stabilizing module, and detection module links to each other with batteries simultaneously, the DC voltage-stabilizing module links to each other with solar battery group, and control module also links to each other with load with batteries.
Described solar-electricity source controller CPU can be PCI16C711, provide 5 volts of power supplys by 7805 chips, as Fig. 2, the DC voltage-stabilizing module can be the DC-DC modular converter, the sample circuit that detection module can be made up of R1, R2, R3 and C1, control module can be separated element with diode D2, D3, D4 etc. by field effect transistor T1, T2 and be formed.PIC16C711 reads the accumulator battery voltage value of the sample circuit sampling of being made up of R1, R2, R3 and C1 by analog-to-digital conversion pin one 8, when accumulator battery voltage is too high, PIC16C711 ends by 1 pin output low level control field effect transistor T1, solar battery group stops battery charging, when accumulator battery voltage is crossed when low, PIC16C711 ends by 2 pin output low levels control field effect transistor T2, stops electric; Batteries and solar cell pass through D2, D3 and R4 respectively to electric; For solar electric power supply system, the solar cell output voltage will change along with the power of sunray, the DC-DC modular converter of solar-electricity source controller described in the utility model with the direct voltage of this variation convert to one fixedly direct voltage output to the control module circuit, as 12 volts of solar electric power supply systems, the DC-DC modular converter converts 5 to 30 volts direct voltages of solar energy output to 16 volts of direct voltages and outputs to the control module circuit, by T1 to battery charging with pass through R4, D3 to electric.
