Summary of the invention:
It is little that the utility model just provides a kind of volume, and the household solar photovoltaic power supply of conveniently moving satisfies the illumination needs in above-mentioned special place.It is made up of solar photovoltaic battery component, plumbic acid maintenance free cell and solar charging/discharging controller, the LED lighting of subsidiary configuration corresponding power.It is direct current energy by the opto-electronic conversion effect of solar module with conversion of solar energy, and is stored in the storage battery by the charging control Driver Circuit of charging-discharging controller, passes through the discharge control Driver Circuit again to the load DC power output.
The utility model adopts the syllogic charging modes by the charging control Driver Circuit of microprocessor program control, it is characterized in that: when the solar photovoltaic battery component generation electric energy of exposing to sunlight, the charging control Driver Circuit begins storage battery is charged, drive field effect transistor and be in complete conducting state, this moment, how many electric energy solar photovoltaic battery component produced, how many electric energy storage battery just can absorb, and this charging stage is called by force fills the stage; When solar photovoltaic battery component continues to charge a battery, the voltage at storage battery two ends raises gradually, and when voltage reached the even charging voltage value, the charging control Driver Circuit transferred the PWM constant voltage charge automatically to, constant voltage voltage lock value is the even charging voltage value, and this stage is referred to as all to fill the stage; When the PWM pulsewidth of all filling the stage was lower than certain value, charging control Driver Circuit automatic switchover constant voltage magnitude of voltage was the float charge voltage value, and this moment, charging current was very little, and this stage is referred to as the floating charge stage or is referred to as tiny stream to fill the stage.The characteristics of this syllogic charging modes are that the charging of storage battery is realized automatic management, can guarantee being full of fast of storage battery, can prevent overcharge again, thereby effectively prolong storage battery useful life.
Discharge control Driver Circuit of the present utility model mainly contains three functions:
1, under-voltage protection: during load discharge, when charging-discharging controller detects battery tension and is lower than the under-voltage protection magnitude of voltage, the power supply of controller disconnecting consumers, thus the protection storage battery can not shorten life-span or damage because of overdischarge.When reaching the recovery voltage value, charge in batteries can recover electric automatically.
2, overvoltage protection: work as accumulator failure, interior resistive is big, and when the storage battery both end voltage was too high, charging-discharging controller detected the too high meeting of battery tension automatic disconnection electric, and the protection load can not damage because of battery tension is too high.Can recover electric after battery tension is normal.
3, load short circuits protection: the patented technology of the solar charging/discharging controller that utilization the applicant has authorized; adopt field effect transistor drain-source conducting resistance to cooperate peripheral components self feed back short-circuit protection circuit; response speed is fast, circuit is simple, efficient is high, self recovery electric after the releasing load short circuits.
Above-mentioned charging-discharging controller of the present utility model adopted advanced technical grade chip to signal gather, analysis, computing and control; and adopt contactless control switch and field effect transistor drain-source conducting resistance Signal Collection Technology; it is more scientific and reasonable to make controller discharge and recharge control, has effectively prolonged the useful life of storage battery and to the safeguard protection of load.
The structure of the utility model power unit comprises: plastic shell, storage battery, charging-discharging controller mainboard.The charging-discharging controller circuit main board is fixed on the procapsid, and storage battery is fixed on the back casing; On the plastic shell procapsid, DC out-put supply switch, working station indicator, DC output port are installed; On the plastic shell back casing, the input port and the DC output port of solar photovoltaic battery component is installed.Each input/output end port, mains switch, working station indicator, and storage battery is connected with the charging-discharging controller circuit main board respectively.
