Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the skill of each exemplary embodiment provided by the present inventionArt scheme is clearly and completely described.In the case where not conflicting, the feature in following each embodiment and embodiment canTo be mutually combined.
Fig. 1 is referred to, is the method for the monitoring main battery and reserve battery charging process of one embodiment of the invention.Wherein,Reserve battery can behave as terminal bonnet or peripheral hardware external member with lithium battery as the secondary power sources of terminal.When main batteryWhen electricity is less than default electricity, reserve battery starts to be powered for terminal, and now, main battery can coordinate reserve battery one to be all endEnd power supply, it is also possible to stop power supply and individually powered by reserve battery.The present embodiment can be using discharge cut-off voltage as main electricityWhether the electricity in pond is less than the criterion of default electricity, if the current discharge voltage of main battery is equal to the type battery currentDischarge cut-off voltage under environment, then judge that the electricity of main battery is less than default electricity, so that the electricity of main battery need not be calculated,It is simple to operate.
With the use of terminal, the electricity of main battery and reserve battery is gradually decreased, when reaching to a certain degree, it is necessary to rightBoth are charged.The method of the present embodiment can include step S11~S14, and these steps can be considered and terminal is chargedCarry out successively afterwards.
S11：First current detecting unit and the second current detecting unit detect the electric current of main battery and reserve battery respectivelyInput information.
So-called electric current input information understandable is whether main battery and reserve battery have electric current to be input into, and further, this is defeatedEnter the charging current whether electric current is equal to main battery.
When the terminal charge, it is assumed that the charging current of main battery be I, then the present embodiment preferably the charging current ISimultaneously for reserve battery charges.
S12：When having detected electric current and exporting respectively to main battery and reserve battery, terminal produces the first charging signals,Charged state is in identify main battery and reserve battery.
S13：Exported to one of main battery and reserve battery only electric current is detected, terminal produces the second charging letterNumber, with the battery charging complete that the battery for being identified with electric current input is in charged state and does not have electric current to be input into.
Under normal conditions, the electricity of the electricity more than reserve battery consumption of main battery consumption, therefore the present embodiment is preferredWith the carrying out charged, reserve battery charging complete first, and main battery continues to charge.In this step, the first current detectingUnit has detected electric current input main battery, and reserve battery is input into without electric current, and terminal produces the second charging signals, to identifyMain battery is in charged state and reserve battery charging complete (i.e. in charging complete state).
When certainly, being less than the electricity that reserve battery is consumed for the electricity that main battery is consumed, in being somebody's turn to do for the present embodimentIn step, the first current detecting unit detects no electric current input main battery, and has electric current to be input into reserve battery, and terminal is producedSecond charging signals, to identify reserve battery, in charged state, main battery is in charging complete state.
S14：Detect do not there is electric current to export to main battery and reserve battery when, terminal produce the 3rd charging signals,Completed with identifying main battery and reserve battery bulk charge.
In the present embodiment, above-mentioned first charging signals, the second charging signals and the 3rd charging signals are pointed out as one kindThe mark of the charging process of user's main battery and reserve battery, can specifically be set according to actual conditions.For example, above threeSignal can specifically be set as at least one in word, terminal speech, jingle bell and the vibrations being shown on terminal screen.
From the foregoing, the embodiment of the present invention is detected respectively by the first current detecting unit and the second current detecting unitThe electric current input information of main battery and reserve battery, and corresponding charging signals are produced according to testing result with identify main battery andReserve battery present charge state such that it is able to so that user promptly and accurately knows the charging process of main battery and reserve battery.
In step s 11, terminal can produce charging clock control signal according to predetermined period, and be sent to the first electric currentDetection unit and the second current detecting unit, wherein the charging clock control signal be used for indicate the first current detecting unit andSecond current detecting unit detects the electric current input information of main battery and reserve battery respectively.That is, pre- at interval of oneIf cycle t, the central processing unit of terminal exports a charging clock control signal, the frequency of the charging clock control signal this hairBright not limited, for example charging clock control signal can export n clock pulses in a predetermined period t, thenFirst current detecting unit and the second current detecting unit are respectively according to predetermined period cycle detection main battery and reserve batteryElectric current is input into information.
Fig. 2 is referred to, when having detected electric current and exporting respectively to main battery and reserve battery, if two neighboring pre-If output to the difference between currents of main battery are more than or equal to the first predetermined threshold value in the cycle, and/or export to the electricity of reserve batteryThe difference of stream is more than or equal to the second predetermined threshold value, then it represents that main battery and/or charging current it is unstable, now, terminal can be withThe the second electric current stabilization unit being connected by the first electric current stabilization unit being connected with main battery and with reserve battery controls to fillThe stabilization input of electric current.Specifically：If it is big to the difference between currents of main battery to detect output in two neighboring predetermined periodIn or equal to the first predetermined threshold value, then terminal is by the stable unit controlled output of the first electric current being connected with main battery to main batteryDifference between currents be less than the first predetermined threshold value；If detect output in two neighboring predetermined period to reserve battery electric current itDiffer from and be more than or equal to the second predetermined threshold value, then terminal stablizes unit controlled output extremely by the second electric current being connected with reserve batteryThe difference between currents of reserve battery are less than the second predetermined threshold value；If exported in two neighboring predetermined period to the electric current of main batteryDifference be more than or equal to the first predetermined threshold value, and output to reserve battery difference between currents more than or equal to the second default thresholdIt is worth, then terminal can be less than by the first electric current stabilization unit controlled output to the difference between currents of main battery being connected with main batteryFirst predetermined threshold value, and the second electric current being connected with reserve battery stablizes the difference between currents of unit controlled output to reserve batteryLess than the second predetermined threshold value.
