[embodiment]
As shown in figures 1 and 3, the utility model solar mobile phone battery comprises housing 9, and lithium battery 12 is housed in housing 9, and described lithium battery 12 is connected with battery protection wiring board 10; On housing 9, also be provided with crystal silicon solar energy battery plate 1; the output terminals A of this solar panel 1, B link to each other with battery protection wiring board 10 and lithium battery 12; solar panel 1 is connected earlier on the battery protection wiring board 10, by linking to each other with cellular li-ion battery 12 behind the battery protection wiring board 10 again.
Among the figure 3 and 4 is respectively a push-button switch and a display device that shows charged state; + ,-port 2 is the output of cellular li-ion battery 12 by battery protection wiring board 10 supply loads-mobile phone body, also is the input when adopting the electric main charging.The input of cellular li-ion battery, output port C, D are connected with input, output port E, the F of battery protection wiring board 10.In the dashed rectangle is the internal structure of conventional batteries plate.
When adopting the charging of sunlight or other luminous energy, solar mobile phone battery is taken off from mobile phone, disconnect the annexation of battery component and load-mobile phone body.Solar panel 1 is placed under the illumination, and at this moment, solar panel 1 is converted into electric energy with luminous energy, and by output terminals A, B output, gives cellular li-ion battery 12 chargings through battery protection wiring board 10.Owing to all have automatic outage and overcurrent, overvoltage crowbar in the battery protection wiring board 10 of former configuration.Therefore, after lithium battery was filled electricity, battery protection wiring board 10 can disconnect automatically, stopped charging, thereby guaranteed the safety of lithium battery and mobile phone; Under the situations such as, overtension excessive at electric current, battery protection wiring board 10 also can be taked safeguard measures such as current limliting, pressure limiting automatically, and lithium battery 12 is protected.Be full of after the electricity, solar mobile phone battery and load-mobile phone body reconnected, insert and be in the same place, lithium battery 12 by wiring board 10 after+,-port 2 provides power supply to load-mobile phone body.
When adopting the electric main charging, electric main after rectification, filtering also from+,-port 2 inputs, give cellular li-ion battery 12 chargings through battery protection wiring board 10.After being full of, lithium battery 12 by input, output port C, D again by wiring board 10 after+,-port 2 output provides power supply to load-mobile phone body.
Charged state display device 4 includes a little LCDs and corresponding protection and electric current, voltage display circuit.When solar mobile phone battery is in when effectively charging under the illumination, press switch button 3, then display device 4 is switched on.But display screen is instant playback charging current and charging voltage just.
In the embodiment of Fig. 2-shown in Figure 4,, 4 additional solar panels 6 (1,2 have been adopted in order to increase the light-receiving area of solar panel, 3,4), replenish solar panel 6 (1,2,3,4) link together with the described solar panel 1 that is arranged on the housing.Replenish battery block 6 (1,2,3,4) and adopt mosaic textures with housing 9, with battery case 9 be the boundary in left and right sides.The chute 5 that replenishes solar cell piece 6 (1) is installed on the battery case 9, and 5 of chutes that replenish solar cell piece 6 (2) are installed on 6 (1), and such 6 (2) just can pull out from 6 (1) behind.Equally, the chute 5 that replenishes solar cell piece 6 (3) is installed on the battery case 9, and 6 (4) chute 5 is installed on 6 (3), and when four additional batteries all launched, its external shape just as shown in Figure 2.All chutes 5 all adopt metal material, so just can be with the chute 5 double usefulness of doing series conductor.The solar panel 1 that replenishes cell panel 6 and be directly arranged on the housing 9 all adopts flake structure, to reduce the thickness of whole battery of mobile phone piece.Because replenish do not contain on the cell panel 6 that output is extreme 2, monitor switch button 3, LCD 4, therefore whole light-receiving area will increase more than 5 times than not establishing the single-sided structure of replenishing cell panel 6.Under the intensity of illumination of AM1.5, charging current can reach more than the 300mA, is full of the time that time of a common lithium ion battery can approach to adopt line charger.
8 is the angular adjustment bar among the figure, its double support usefulness of doing, and 7 is rotating shaft.Because the angle difference of irradiate light to the battery, the light intensity that solar cell obtains are also different, thereby the power output that obtains also has very big difference.For example: get a kind of more typical solar energy energy mobile phone charger, it is made up of 16 fritter monocrystaline silicon solar cell sheets, and long is 10.6cm, and wide is 7cm, removes four leg-of-mutton corners and edge, and the illumination effective area that obtains is roughly 5000mm
2, under common light intensity (AM1.5), charging current is 110～115mA.Adjust the angle of solar panel over against solar light, at this moment the charging current of Huo Deing is 160～165mA.Short circuit current has increased more than 45%.This example shows that it is necessary that an angle regulator is set on solar mobile phone battery.Anglec of rotation adjusting rod 8 change solar mobile phone battery plates and solar light over against angle, the electric current and the voltage that show will change, and be presented on the charged state display device 4, the angle of the maximum charging current that obtains be solar panel the best over against angle.
From Fig. 3, it can also be seen that, in the present embodiment,, comprise 1 and 6, and between the lithium battery 12, be provided with thermal insulation layer 11 at described solar panel.Thermal insulation layer 11 can at solar cell during in the high light direct projection, be isolated lithium ion battery 12, makes its surperficial temperature unlikely too high, with the fail safe that guarantees lithium battery 12 and good charging performance.In addition, as shown in Figures 2 and 3, in the present embodiment, solar cell is installed on the inner surface of battery of mobile phone housing, has so just guaranteed the consistency of battery of mobile phone outer surface and former mobile phone body.
Solar cell is composed in series by 16 fritter batteries, and material is monocrystalline silicon or polysilicon.The number of solar battery sheet is directly relevant with output voltage.Make output voltage too high too much easily, then do not reach required charging voltage very little, be used for the charging of Li-Ion rechargeable battery, above-mentioned number is the most suitable.
When battery of mobile phone need charge, battery of mobile phone is placed under the sunray, when illumination is taken at the light intensity of AM1.5, the open circuit voltage V that solar cell 1 obtains
OcAbout 8V, short circuit current V
ScAbout 350mA.When solar cell 1 was connected as a single entity with wiring board 10 and battery 12, output voltage descended, and is reduced to 3.65～4.35V, promptly reaches the charging voltage of lithium ion battery, and this moment, output current sharply increased.Fig. 5 shows the dynamic characteristic of solar cell 1, the active section when having marked its charging among the figure, and when beginning lithium ion charged, voltage is lower, V in the corresponding diagram
Min, along with the prolongation in charging interval, charging voltage increases gradually, reaches maximum V when lithium battery is filled
Max, charging current is then by maximum I of when beginning
MaxCarry out the transition to minimum I
Min, very little because charging voltage changes, so changing, charging current roughly remains in the 5mA, can regard constant current charge as basically.The charging current of whole process is roughly about 300mA.Press button 3, on display screen 4, just show this charging voltage and charging current, adjust support bar 8 and just can obtain best charging effect.
When the light intensity of accepting when solar cell 1 was not enough, the voltage at AB two ends sharply descended, and the voltage of this moment can be reduced to charging voltage V
MinBelow.When a kind of limiting case is placed in battery of mobile phone on the mobile phone body exactly (this is the situation commonly used of battery of mobile phone), solar cell is not accepted irradiate light, and the output voltage of AB end is 0.This moment, lithium ion battery 12 was powered to mobile phone by output 2, and this moment, solar cell was in the reverse charge state.Prior art such as Chinese patent ZL99226406.5, ZL00259388.2 etc. all set forth must add an anti-backflow device between solar cell and lithium ion battery.This there is no need fully in fact.When area is 5000mm
2Above monocrystalline or polysilicon solar cell are 0 o'clock in light intensity, its inner equivalent resistance is more than 10M Ω, at this moment, the electric current of lithium battery by solar battery sheet discharge is about 1.0 μ A, if discharge by solar battery sheet merely, then needed the battery that a capacity is 600mAh could have been put in 25000 days.When illumination was arranged, its equivalent resistance can be bigger, and the series connected battery area is big more, and resistance is also big more.Therefore, be that negligible fully, designed experiment has also proved this conclusion owing to reverse charge makes the energy of lithium ion battery consumption.Adopt diode or triode to be used as anti-counterflow element as saying by patent ZL99226406.5, ZL00259388.2, then reverse charge stream does not have remarkable minimizing, because this moment, reverse current is less than the reverse leakage current of diode or triode.Diode or triode of series connection in this external circuit only can increase the droop loss of circuit greatly, has no benefit and fill for counnter attack.Therefore, solar cell directly can be connected on the battery protection wiring board.Thereby simplified circuit structure, reduced cost.
