The circuit structure block diagram of preferred embodiment of the present invention as shown in Figure 1, portable terminal of the present invention comprises: a baseband chip 1, a rechargeable battery 3, a solar panel 4, a linear voltage regulator 5.
In the present embodiment, in order better to control low pressure, linear voltage regulator 5 has adopted LDO (low pressure difference linear voltage regulator).Wherein, this baseband chip 1 controls whether will be converted into stable charging voltage from the electric energy that solar panel 4 receives through the linear voltage regulator 5 that control is connected with solar panel 4, and to rechargeable battery 3 chargings.Wherein this baseband chip 1 can also be tested the voltage of rechargeable battery 3, thereby can monitor the electric weight of rechargeable battery 3 voltages.In addition, can also comprise a battery discharge module 6, when baseband chip 1 detected the too high and temperature anomaly of rechargeable battery 3, this battery discharge module 6 can discharge unnecessary charging voltage, thereby has guaranteed the charging safety of rechargeable battery 3.
This portable terminal can also comprise a temperature sensor 7 in addition; The charging temperature of these temperature sensor 7 monitoring rechargeable batteries 3; And feed back corresponding temperature data and give baseband chip 1; When temperature exceeds the charging temperature scope of rechargeable battery 3, thus this baseband chip 1 can control linear voltage regulator 5 and stop solar recharging rechargeable battery 3, thereby guaranteed the charging safety of rechargeable battery 3.
The solar recharging operation principle of portable terminal is among this embodiment:
The getable electric energy of solar panel 4 convert light at first obtains stable charging voltage through linear voltage regulator 5.This linear voltage regulator 5 receives baseband chip 1 control then.If close solar recharging, just control this linear voltage regulator 5 and quit work.If open solar recharging, baseband chip 1 is just controlled this linear voltage regulator 5 work.Temperature sensor 7 is used to measure the temperature of rechargeable battery 3 and sends to baseband chip 1 in addition; If temperature is not in the charging temperature scope of rechargeable battery 3 time; Then this baseband chip 1 is closed linear voltage regulator 5 and is stopped solar recharging, and baseband chip 1 is gone back the voltage of energy measurement rechargeable battery 3 simultaneously.Whether the voltage of test rechargeable battery 3 surpasses the charging deboost of rechargeable battery 3, thereby whether controls linear voltage regulator 5 to these rechargeable battery 2 chargings.If the overtension of rechargeable battery 3 and temperature anomaly then need give rechargeable battery 3 discharges in addition, baseband chip 1 discharges through control battery discharge module 6.The state of this solar charging device can show with display screen 2 through baseband chip 1 control indicator light 8 in addition.
From the above mentioned, this solar charging device can be realized solar recharging on portable terminal, promptly has sunlight just can charge, thereby brings great convenience to the user, and this function of solar charging has not only guaranteed the fail safe of charging simultaneously.
Fig. 2 is the flow chart of preferred embodiment of the method for solar recharging.It is as shown in Figure 2,
Step 101, flow process begins.
Whether step 102, baseband chip detect has charger to insert in the portable terminal, if there is charger to insert in this portable terminal; Then baseband chip is closed battery discharge module, linear voltage regulator and indicator light; And this baseband chip also control display screen shows insertion charger information, gets into step 112 then; If do not have charger to insert in this portable terminal, then get into step 103.
Whether step 103, baseband chip test charged battery voltage greater than the charging deboost, if test result is for being then to get into step 104, otherwise entering step 107.
Step 104, whether baseband chip test battery temperature is in outside the charging temperature scope, if test result for being, then gets into step 105, otherwise gets into step 106.
Step 105; Baseband chip is closed linear voltage regulator; Thereby closed the solar recharging of rechargeable battery, this baseband chip has been opened the battery discharge module rechargeable battery has been discharged simultaneously, and also the control display screen displays temperature is unusual for this baseband chip in addition; The information warning of electric voltage exception is lighted indicator light simultaneously.Get into step 112 then.
Step 106, baseband chip is closed linear voltage regulator, thereby has closed the solar recharging of rechargeable battery, and charging is accomplished.Get into step 112 then.
Step 107, whether baseband chip test battery discharge module is opened, and promptly whether rechargeable battery is in discharge, if test result for being, then gets into step 108, if test result then gets into step 109 for not.
Step 108, baseband chip are closed the battery discharge module, promptly stop the discharge of rechargeable battery.
Step 109, whether baseband chip test battery temperature is in outside the charging temperature scope, if test result for being, then gets into step 110, otherwise gets into step 111.
Step 110, baseband chip is closed linear voltage regulator, thereby has closed the solar recharging of rechargeable battery, and this baseband chip unusual information warning of control display screen displays temperature is also lighted indicator light simultaneously in addition.Get into step 112 then.
Step 111, baseband chip is opened linear voltage regulator, thereby has opened the solar recharging of rechargeable battery, in addition this baseband chip also control display screen show the information of solar recharging, close indicator light simultaneously.
Step 112, flow process finishes.
As long as this flow chart shown in the continuous service chart 2 in portable terminal; Whether voltage and the temperature that just can judge the rechargeable battery in the portable terminal are in a safe condition; If be in non-safe condition then close function of solar charging at once; And give user's corresponding prompt, thereby in solar recharging, guaranteed the safety of solar recharging.
Fig. 3 is the schematic flow sheet of baseband chip test charged battery voltage.It is as shown in Figure 3,
Step 1031, baseband chip is closed linear voltage regulator, thereby has closed the solar recharging of rechargeable battery.
Step 1032, baseband chip is tested the voltage of rechargeable battery.
Step 1033, baseband chip is opened linear voltage regulator, thereby has opened the solar recharging of rechargeable battery.
Because when measuring the voltage of rechargeable battery in the portable terminal, if rechargeable battery is just at solar recharging at this moment, the voltage of the rechargeable battery of then measuring will be higher, brings the accuracy problem of measurement.So the present invention has adopted when portable terminal is measured the voltage of rechargeable battery, closes solar recharging earlier,, opens the voltage of measuring rechargeable battery the method for function of solar charging when finishing again.Because the time of the voltage of portable terminal measurement rechargeable battery is very short to be Millisecond, voltage method of this test rechargeable battery does not influence the performance of solar recharging.
Though more than described embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these execution modes under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
