Embodiment
Below in conjunction with drawings and the embodiments mixed power supply system of the present invention is described in further detail.
See also Fig. 1, mixed power supply system 100 comprises civil power incoming end 20, solar panel 22, electrical storage device 23, controller 25, electric energy sensing apparatus 26, switching device shifter 27 and switching device 28.Mixed power supply system 100 is load 30 power supplies, and in the present embodiment, load 30 is a lighting device.
Solar panel 22 is connected with electrical storage device 23, and it can be electric energy with conversion of solar energy and be stored in the electrical storage device 23.Electric energy sensing apparatus 26 sensings flow into the current value and the magnitude of voltage of electrical storage devices 23 from solar panel 22, calculating the electric energy that solar panel 22 charges into electrical storage device 23, and this energy value are sent to controller 25.The maximum capacitance of electrical storage device 23 generally greater than 22 daytimes of solar panel under the sufficient situation of illumination to 23 charge volumes of electrical storage device.
Switching device shifter 27 is a switch combination, and electrical storage device 23 all is connected with load 30 through switching device shifter 27 with civil power incoming end 20.Switching device shifter 27 can optionally make electrical storage device 23 or civil power incoming end 20 and load connect, to select the powering mode of load 30 under the control of controller 25.Switching device 28 is located between civil power incoming end 20 and the electrical storage device 23, and switching device 28 is used to control being switched on or switched off of civil power incoming end 20 and electrical storage device 23.Controller 25 controllable switch devices 28 make civil power incoming end 20, and electrical storage device 23 is in connected state, are electrical storage device 23 chargings by civil power incoming end 20 then.Generally also be provided with current converter (figure do not show) on the electrical storage device 23, charge in the electrical storage device 23 after civil power is converted into direct current.
If the illumination abundance, electric energy sensing apparatus 26 records solar panel can satisfy load 30 need for electricity from 22 daytimes to 23 charge volumes of electrical storage device.During load in evening 30 work, controller 25 control switch device 27 are connected electrical storage device 23 and load 30, are load 30 power supplies.Daytime next day, solar panel 22 was electrical storage device 23 chargings once more.
As if solar irradiation deficiency on daytime, solar panel 22 gained electric energy can not hold electrical storage device 23 full, electric energy sensing apparatus 26 records energy value that electrical storage device 23 holds, power calculation according to load 30 draws 23 operating times that can keep load 30 of electrical storage device, when controller 25 electric energy in electrical storage device 23 can not be kept load 30 operate as normal, control switch device 27 is connected civil power incoming end 20 and load 30, makes civil power incoming end 20 be load 30 power supplies.Simultaneously, controller 25 is connected switching device 28, makes civil power incoming end 20 be electrical storage device 23 chargings.
Above-mentioned civil power incoming end 20 is controlled process system device 25 controls of electrical storage device 23 chargings.If the maximum capacitance of electrical storage device 23 is Ef, the electric weight Ed that the same day, solar panel 22 was filled for electrical storage device 23.When switching device 28 is connected civil power incoming end 20, charge in the electrical storage device 23 electric energy for or when being slightly smaller than Ef-Ed, controller 25 control switch devices 28 disconnect, control civil power incoming end 20 is not full of when charging for electrical storage device 23, reservation is the charging space of Ed more than or equal to capacitance, the electric energy that next day, solar panel 22 was transformed can be stored in the electrical storage device 23, make full use of solar energy.
If illumination on same day deficiency causes 23 charge capacities of electrical storage device can not satisfy load 30 needs for electricity, when mixed power supply system 100 is powered at night, civil power is inserted, civil power incoming end 20 is load 30 power supplies, be electrical storage device 23 chargings simultaneously, in order to the situation of civil power outage, and controller 25 these charging processes of control, in electrical storage device 23, reserve certain charging space for charging next day.
If illumination next day is still not enough, then the solar panel on daytime of next day 22 can be full of electrical storage device 23 just; If next day, weather took a turn for the better, the illumination abundance, then the solar energy that received of solar panel 22 is converted into electric energy, has at least part to be stored in the electrical storage device 23 then, has improved solar energy utilization rate.Mixed power supply system 100 is a benchmark with the energy storage situation on the same day, reserves the charging space of next day, and is especially suitable in the period that the illumination situation is not enough continuously, as overcast and rainy continuously, in the winter that illumination is lower, can obviously improve solar energy utilization rate.
Also can the over-charge protective device be set on electrical storage device 23, when the electrical storage device electric weight is full of, cut off the electric current that comes from solar panel 22 automatically, do not overcharged and be damaged with protection electrical storage device 23.
Certainly, switching device shifter 27 can omit, and load 30 is connected with load 30, is load 30 power supplies by electrical storage device 23.When solar panel charged into electric energy Ed in the electrical storage device 23 22 same day can not offered load 30 operate as normal the time, controller 25 control switch devices 28 closures, civil power incoming end 20 is electrical storage device 23 chargings, electrical storage device 23 is load 30 power supplies simultaneously, controller 25 is according to the difference of 23 charge and discharges of electrical storage device in the unit interval, the closing time of control switch device 28 is solar panel 22 reservation Ed or bigger charging spaces next day in electrical storage device 23.
In addition, those skilled in the art also can do other variation in spirit of the present invention.Certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
