Photocell in the embodiment of the invention only just generates electricity when illumination is arranged.Wherein, when having judged whether illumination, can judge according to following method:
Illumination is mapped to and produces " photovoltage " on the photovoltaic panel, judges magnitude of voltage substantially constant under the different illumination intensity according to the I-V curve, and only voltage is zero under unglazed situation, and controller detects voltage and promptly has been judged to be illumination.Fig. 4 shows the influence of intensity of sunshine to solar module.
When illumination was arranged, controller control solar cell generated electricity automatically, and storage battery needs charging; Controller control solar cell charges a battery, if battery is full of, cuts off solar cell automatically; Be off state; If refrigerator has the electric weight demand, directly to the refrigerator power supply, storage battery can discharge and recharge storage battery simultaneously.
When unglazed the photograph, supply power to refrigerator by storage battery.
Photocell produces photovoltaic voltage and supplies power to controller; TVS is a Transient Voltage Suppressor; Prevent that photocell electric voltage exception damage controller and internal circuit MCU computer controller from judging whether to charge a battery according to the charge in batteries characteristic curve, carry out storage battery PWM serial connection charge through control pwm power driver module control switch Q1, Q2.Whether unusual at output output protection and power driver module according to the current value judgement output that current sensor S1 tests; Overpower whether; Simultaneous temperature transducer T1 does overtemperature protection, and when the controller heatsink temperature surpassed 85 ℃, controller can cut off input, output loop automatically; Make battery-operated simultaneously under desirable operating state, prolong storage battery useful life.Excessive when the photocell electric current that charges a battery, fuse FUSE breaks off with the protection storage battery.
Storage battery can discharge and recharge simultaneously: photocell and storage battery constitute charge circuit, and storage battery and refrigerator constitute discharge loop, and charge circuit and discharge loop are for being connected in parallel on the storage battery two ends.When detecting battery and need charge, switch Q1 and switch Q2 open and charge a battery.Discharge end is connected on the controller of refrigerator, and refrigerator controller is according to the start-stop of the variation control freezer compressor of internal temperature of refrigerator.
When storage battery need not charge, switch Q1 and switch Q2 turn-offed, and this moment, photocell was in unloaded open-circuit condition, and illumination more strongly can be not lossy yet.Can reduce the loss of photovoltaic cell module like this, reduce hot spot effect.Prolong the photronic life-span.
Control circuit of the present invention can comprise battery charging circuit and system's power supply circuits, through adopting autonomous power supply system, need not the self discharge circuit, has effectively improved the stability and the life-span of assembly.Storage battery can discharge and recharge operation simultaneously, has improved the utilance of photovoltaic generation greatly.
Fig. 5 shows controller 2 corresponding input/output relations; Controller 2 is judged the whether needs charging of storage battery according to solar array voltage and battery tension signal 1 and charge in batteries characteristic curve 5; And to storage battery discharge and recharge control 3; And can carry out various demonstrations 4, for example, the solar cell output voltage shows, the storage battery output voltage shows, the load charging current shows, charged state shows, demonstration and alarm demonstration etc. make mistakes.
When the pwm power driver module drives the first switch Q1 and second switch Q2 closure; Promptly make storage battery and photocell constitute charge circuit; Owing to adopt advanced tandem type pulse-width modulation (PWM) mode, 0 to 100% wide region PWM regulates can be to the charging of storage battery fast and stable.
Below charging process of the present invention is described in detail, as shown in Figure 6, charging process comprised with the next stage:
Quick charge stage (for example, 28.4V～31V)
In the quick charge stage, battery tension is not charged to the set point that is full of voltage as yet, and it is charge in batteries that controller will provide 100% available solar energy electric weight.
Improvement stage (for example, 27.6V～28.4V)
When charge in batteries arrived the set point of booster tension, controller constantly regulates charging current so that battery tension maintains the booster tension set point.Can prevent that like this storage battery is overheated, prevent that storage battery from producing gas.It is 120 minutes that storage battery remains on the time accumulative total that promotes the charging stage, forwards the floating charge stage then to.
The floating charge stage (for example, 26.4～27.6V)
After promoting the charging completion, controller then changes the floating charge control stage over to.After storage battery is full of fully, just no longer include more electrochemical reaction, at this moment all charging currents are converted into heat and bubbing.At this moment get into the floating charge stage, the floating charge stage charges with littler voltage and current, and in temperature that has reduced storage battery and bubbing, the floating charge stage is carried out very faint charging like this.The purpose of floating charge is the electric quantity consumption of compensation storage battery because of the less load generating of self discharge and system, keeps the full of accumulators store electric weight simultaneously.In the floating charge stage, load can continue to obtain electric power from storage battery.If the load of system has surpassed the solar recharging electric current, controller will no longer can maintain the floating charge set point to battery tension.Promote charging (26.4V) recovery set point if battery tension is lower than, controller will withdraw from the floating charge stage, get back to the quick charge stage.
When battery tension is lower than 25.2V, can low pressure break off with recovery voltage, can be set to the deboost that discharges with 21.6 volts with 24.4V as undervoltage alarm voltage.
When battery tension greater than discharge deboost (21.6V), storage battery is uninterruptedly to refrigerator power supply, whole charging and discharging process display screen can display module 4 corresponding state informations.
As shown in Figure 7, refrigerator CPU20 sets situation 50 according to temperature 10 and user in ring temperature and the refrigerator body and judges whether parts such as press, air door, blower fan, heater strip work, and shows 40 corresponding work state and parameters.
Need to prove that discharging and recharging the control of control and refrigerator can be that a controller is independently accomplished, and also can be to be divided into two independent controls to control respectively, that is, the CPU among Fig. 5 and Fig. 7 can refer to same controller, also can refer to two Different control devices.

Step S602, whether detect storage battery needs charging;
Step S604, when definite storage battery need charge, the control photocell charged to storage battery;
Step S606 when definite storage battery need not charge, then controls photovoltaic cell and storage battery and breaks off.
In the method, owing to only supply power to solar energy refrigerator through storage battery, and when storage battery need not charge, photovoltaic cell need not to charge a battery, thereby had reduced the photocell loss, had prolonged photocell useful life.
Preferably, the control photocell charges to storage battery and comprises: controller detects the electrical energy parameter of storage battery; If greater than second parameter value, then controller control photovoltaic cell is taked the quick charge mode to storage battery to the electrical energy parameter of storage battery less than first parameter value; If greater than the 3rd parameter value, then controller control photovoltaic cell takes to promote charging modes to storage battery to the electrical energy parameter of storage battery less than second parameter value; If greater than the 4th parameter value, then controller control photovoltaic cell is taked the floating charge mode to storage battery to the electrical energy parameter of storage battery less than the 3rd parameter value.Through this r, not only can guarantee to charge efficiently, and can improve the life-span of storage battery.
