Embodiment
Below with reference to specific embodiment, the technical scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of portable intelligent solar charger, comprise PCB 1, photovoltaic battery panel 2, battery pack 3, described PCB is connected with photovoltaic battery panel 2, battery pack 3 respectively; Described PCB 1 is made up of Charge Management IC module 11, battery protection ic module 12, DC/DC boost chopper 13, single-chip microcomputer 14, display circuit 15, load circuit 16 and key-press module 17, and described Charge Management IC module 11 is connected with photovoltaic battery panel 2; Described battery protection ic module 12 is connected with Charge Management IC module 11, DC/DC boost chopper 13, battery pack 3 respectively, and Charge Management IC module 11, battery protection ic module 12 are all connected with DC/DC boost chopper 13; Described single-chip microcomputer 14 is connected with DC/DC boost chopper 13, key-press module 17, display circuit 15 respectively, and DC/DC boost chopper 13 is also connected with load circuit 16; The delivery outlet 4 of described charger is USB interface.
The charger utilizing of the present utility model light of solar energy-electric transition effects, solar light irradiation is allowed to make solar energy be converted into electric energy on photovoltaic battery panel 2, through Charge Management IC module 11, obtained electric energy battery backup 3 is stored, in the end exported to the electric energy of load by USB delivery outlet 4 before, also will through DC/DC boost chopper 13(boost chopper circuit) carry out boosting process.If lithium battery carries out the constant current charge of overall process, inside battery structure can be damaged, greatly shorten the life-span of battery.In order to better preserve battery capacity, usual first is first carried out trickle charge, carries out constant current charge more after a while, just the 3rd step must wait until that cell voltage starts last constant voltage charge when rising to set point.Charger have employed modular organization, and delivery outlet 4 is also USB interface, can charge to multiple mobile digital product, as mobile phone, and panel computer, MP4 etc.Causing cell damage in order to avoid overcharging in charging process, adopting over-voltage over-current protection, and being shown by the LED of display circuit 15.
With general mobile phone, digital product charger is compared, portable type solar energy charger of the present utility model, not only solar energy directly can be turned to electric energy by battery pack 3 to charge for mobile phone, make full use of the intelligent of single-chip microcomputer 14 in addition, devise very fully ripe measure voltage & current protective circuit, the state of circuit is embodied by LED display circuit 15, if when running into overcast and rainy or outdoor optical photograph insufficient strength, the battery pack 3 of charger internal is mobile phone charging, now charging indicator light extinguishes, and when outdoor optical is according to time enough strong, rechargeable battery starts by solar panel electric power storage, photovoltaic battery panel 2 is also powered directly to mobile phone, the charging indicator light of display circuit 15 also can be lit simultaneously.When becoming a fine day, sunny, solar photovoltaic cell panel 2 is put direct projection in the sun, utilizes solar energy to charge for mobile phone; If there is the place of power supply in indoor, the USB interface of delivery outlet 4 also can be adopted to charge to battery pack 3, in advance storage battery is full of, to deal with emergency situations.
During concrete enforcement, as shown in Figure 3, wherein DC/DC boost chopper 13 as shown in Figure 4, and as shown in Figure 5, described Charge Management IC module 11 adopts CN3063 chip to PCB schematic diagram for overall circuit theory diagrams; Described battery protection ic module 12 adopts DW01 chip; Described DC/DC boost chopper 13 adopts G5177B chip; Described single-chip microcomputer 14 adopts STC15W201S chip.In the process that solar charger runs, first solar light irradiation is on photovoltaic battery panel 2, is electric energy, exports to late-class circuit by opto-electronic conversion effect by light energy conversion.The electric current exported is charged into battery pack 3 by chip CN3063, and chip CN3063 can control electric current makes charging process be divided into trickle charge, constant current charge, constant voltage charge three phases, and this is to lithium battery group charging modes the most safely and effectively.Battery pack 3 in charging and charging complete time, the pin 6 of chip CN3063 and pin 7 respectively can output low levels, can light corresponding LED, to show the charged state of present circuit through single-chip microcomputer 14.Connect a DC/DC boost chopper 14 after lithium battery group, the voltage of lithium battery group 3.7V is elevated to about 5V, just can normally carry out having charged after such successive load connects.Lithium battery group two ends connect chip DW01 more in addition, and this is a charging protective circuit of lithium cell.By the detection to lithium battery current voltage, judge that whether charging process is normal, whether there is super-charge super-discharge phenomenon.When circuit charges normal, OD, OC foot control contactor of chip DW01 closes, circuit communication; When detecting discovery battery pack and having super-charge super-discharge phenomenon, OD, OC pin can disconnect by corresponding control switch, cuts off circuit, stops charging process, so just can play the effect of protection lithium battery group.The level signal of OD, OC pin of chip DW01 also can send single-chip microcomputer 14 to simultaneously, lights corresponding LED, to observe the state of circuit by single-chip microcomputer 14.This makes it possible to realize a complete solar charger function.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and non-limiting technical scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
