Embodiment
In the charge control method and electronic equipment of the embodiment of the invention; In the charging process; Confirm that according to the charging current of rechargeable battery parameter confirms charging current; Make that the charge rate of rechargeable battery is positioned at a pre-set interval in this charging process, cause expiring of rechargeable battery to fill the capacity problem of decay rapidly, prolong the useful life of rechargeable battery to reduce the too high meeting of charge rate.
Embodiment for a better understanding of the present invention, below earlier following to will be referred to a plurality of conceptual illustration.
Rated capacity shows a parameter of the heap(ed) capacity that battery can provide, and like 1600mAH, this parameter is just definite after the rechargeable battery manufacturing is accomplished, and is a theoretical parameter.
(Full Charged Capacity FCC), shows a parameter of the current capacity of battery, characterizes the current electricity capacity afterwards that is full of of rechargeable battery completely to fill capacity; This parameter in time, the variation of environment and changing; As in the starting stage of the life cycle of rechargeable battery, completely filling capacity maybe be roughly the same with rated capacity, and in the final stage of the life cycle of rechargeable battery; Completely fill capacity much smaller than rated capacity, as have only 60% of rated capacity.
Should be understood that; This completely fills the demonstration that capacity is different from battery capacity percentage in the ordinary electronic equipment; When battery capacity percentage in the ordinary electronic equipment is no matter; This battery capacity can reach 100%, but this 100% just show battery be in be full of the electricity state, do not represent its actual capacity.
Charge rate (Charging Rate) is charging current and the merchant who completely fills capacity, and charge rate is too high, can cause expiring of rechargeable battery to fill capacity and decay rapidly, shortens the useful life of rechargeable battery;
A kind of charge control method of the embodiment of the invention is used for the control of charging of rechargeable battery to electronic equipment, and said charge control method is as shown in Figure 1, comprising:
Step 11 during the charging beginning, is obtained the charging current of said rechargeable battery and is confirmed parameter;
Step 12 confirms that according to the charging current of obtaining parameter confirms the charging current of this charging;
Step 13 in this charging process, adopts the charging current of confirming that said rechargeable battery is charged, and makes the charge rate of said rechargeable battery be positioned at a pre-set interval.
In the control method of the embodiment of the invention; It no longer is a kind of mode of constant current charge; But confirm that according to the charging current that this when beginning charging gathers parameter confirms the charging current of this charging; And then charge with the charging current of confirming, make the charge rate of said rechargeable battery be positioned at a pre-set interval, charge rate is excessive fills capacity to rechargeable battery expiring of bringing and decays rapidly to avoid.
In specific embodiment of the present invention, the size of this pre-set interval can be confirmed according to demand, as for the electronic equipment of built-in rechargeable battery; If under the situation that the design of electronic devices life-span itself just relatively lacks; Be longer than the electronic equipment life-span and get final product owing to only need to guarantee the life-span of rechargeable battery, so the upper limit of this pre-set interval can be provided with bigger, certain; If under the long situation of design of electronic devices life-span, then the upper limit of this pre-set interval need be provided with smaller.
And for example, for all rechargeable batteries, need charge after its electric weight uses up, and charging current is big more; Then the charging interval short more, but charge rate is high more, if to top-priority words of the charging interval of electronic equipment; Then the upper limit of this pre-set interval can be provided with bigger, can be greatly to guarantee charging current, make the charging interval shortening; Otherwise then can the upper limit of pre-set interval be provided with smallerly, sacrifice the charging interval and reduce charge rate, prolong the life-span of rechargeable battery.
But should be understood that, in specific embodiment of the present invention, this charging current is set howsoever, all need make in any charging process, guarantee that the charge rate of rechargeable battery is positioned at pre-set interval, avoid the too high situation of charge rate.
In specific embodiment of the present invention, this pre-set interval can be a point, is under the situation of a point in pre-set interval, and it is exactly to make the charge rate of rechargeable battery equal this preset value that the above-mentioned charge rate that makes said rechargeable battery is positioned at a pre-set interval.
Whole life from rechargeable battery; In charging process; Adopt the charging current of confirming that said rechargeable battery is charged; Make the charge rate of said rechargeable battery be positioned at a pre-set interval, second charging process that is equivalent to make said rechargeable battery have first charging process and after first charging process, takes place, the charging current of said first charging process is greater than the charging current of said second charging process.
Certainly, this first charging process and second charging process can be twice adjacent charging processes, also can be non-conterminous twice charging processes, illustrate as follows respectively.
Suppose that this pre-set interval is a point, first charging process is the n time charging process, and second charging process is the n+1 time charging process, and the charging current of supposing the n time charging process is I
1, because the battery that the battery of the n+1 time charging process when beginning completely fills capacity can begin less than the n time charging process the time completely fills capacity, keeping charge rate if desired is a steady state value, then the charging current of the n+1 time charging process is I
2Must be less than I
1Keep a constant charge rate through continuous reduction charging current, avoid that charge rate is excessive fills capacity to rechargeable battery expiring of bringing and decay rapidly.In this case, the charging current of twice adjacent charging process is different.
Suppose that this pre-set interval is a scope, first charging process is the n time charging process, and second charging process is the n+1 time charging process, and the charging current of supposing the n time charging process is I
1, because the battery that the battery of the n+1 time charging process when beginning completely fills capacity can begin less than the n time charging process the time completely fills capacity, reduce lessly if battery completely fills capacity, use charging current I at this moment
1Also can make charge rate be positioned at pre-set interval, but when n+m charging, through m charging and discharging, battery completely fills capacity and reduces a lot, use charging current I this moment
1Can't make charge rate be positioned at pre-set interval, need the reduction charging current to keep charge rate and be positioned at pre-set interval.In this case, in this case, the charging current that is charged to the n+m-1 time charging process for the n time is identical, but the charging current of the n+m time charging process is different with the charging current of n charging process.
In specific embodiment of the present invention, in the time of charging, need the charge rate of control rechargeable battery to be positioned at a pre-set interval, can realize in several ways that in specific embodiment of the present invention explanation is as follows respectively.
< implementation one >
In implementation one, when each charging, all confirm charging current.
Under this implementation, said charging current confirms that parameter is the current capacity that completely fills of said rechargeable battery.
Mention before; Charge rate (Charging Rate) is charging current and the merchant who completely fills capacity; And completely fill capacity is can (Battery Management Unit, the data in BMU) directly obtain through reading the chip battery management unit that rechargeable battery carries.
Completely fill under the definite situation of capacity current, make that charge rate is positioned at pre-set interval, need guarantee that then charging current is positioned at the interval interval with the product place of completely filling capacity of charge rate and gets final product.
By the way, when each charging process begins, all obtain the current capacity that completely fills through BMU; And then completely fill capacity to confirm to make that charge rate is positioned at the interval charging current of charge rate interval according to current, and then get a value arbitrarily from the charging current interval and get final product, certain; If think further to prolong the life-span of rechargeable battery, then can select interval lower limit, and if think to be full of as early as possible; Then can select interval higher limit, but no matter be higher limit or lower limit, charge rate all can be positioned at pre-set interval; The too high situation of charge rate can not take place, and can prolong the life-span of rechargeable battery with respect to the mode of existing constant current charge.
< implementation two >
In mode one, when each charging beginning,, and then confirm to make that according to the current capacity that completely fills charge rate is positioned at the charging current of pre-set interval all through reading the current capacity that completely fills of rechargeable battery.
But whole life from rechargeable battery; Guarantee if desired to make in whole what cycle that charge rate all is positioned at a pre-set interval; Also can whole life be divided into multistage according to certain characteristic; Each section makes charge rate all be positioned at the charging current of a pre-set interval corresponding to one, owing to be divided into multistage, can reduce the variable quantity that expiring of each section fill capacity; Make that in a certain period, using a constant electric current to charge also can make charge rate be positioned at the charging current of a pre-set interval, specifies as follows.
Supposing the whole life from rechargeable battery, is example with the battery cycle-index, supposes in begin most 400 times circulations, and the expiring of battery fills capacity and be positioned at (0.9 rated capacity; 0.999 rated capacity) this interval, and since the 400th circulation in the stage of the 500th circulation, the expiring of battery, fill capacity and be positioned at (0.7 rated capacity, 0.9 rated capacity); And surpass after 500 circulations, the expiring of battery, fill capacity and can drop under 0.7 rated capacity, at this moment, supposes that pre-set interval is [A; B], can find this moment, for preceding 400 circulations; The interval that only needs the assurance electric current is that the common factor of [0.9A, 0.9B] and [0.999A, 0.999B] gets final product.
In implementation two; The charge mode of said rechargeable battery comprises at least two kinds of charge modes; Each charge mode is corresponding to different charging currents, and when with the corresponding charging current of each charge mode said rechargeable battery being charged, the charge rate of said rechargeable battery all is positioned at pre-set interval; Said charging current confirms that parameter is that a pattern judges that parameter, the charging current that said basis the is obtained charging current of confirming this charging that gets parms is specially:
Judge the parameter charge mode that definite this charging is adopted from said at least two kinds of charge modes according to said pattern;
To confirm as the charging current of this charging with the corresponding charging current of confirming of charge mode.
Consider that recycling number of times and chargeable electric core is to influence 2 bigger factors that battery completely fills capacity attenuation with the accumulated time that is higher than the predetermined voltage storage; Therefore; In specific embodiment of the present invention, said pattern judge parameter be said rechargeable battery recycle number of times and/or said chargeable electric core to be higher than the accumulated time of predetermined voltage storage.
When the two unites use; Said pattern judge parameter be said rechargeable battery recycle number of times and said chargeable electric core to be higher than the accumulated time of predetermined voltage storage; And said at least two kinds of charge modes are first charge mode and second charge mode, and said charge mode according to definite this charging employing from said at least two kinds of charge modes of said pattern judgement parameter is specially:

That is to say; For the battery of starting stage completely filled capacity, to recycle number of times more when battery, and perhaps chargeable electric core is with the accumulated time that is higher than the predetermined voltage storage when longer; The expiring and fill capacity decay all can be arranged largely of battery this moment; Need guarantee that charge rate is positioned at pre-set interval this moment through the mode that reduces charging current, therefore need reduce charging current, is positioned at pre-set interval otherwise keep constant its charge rate that can make of charging current.
Charging in a period of time all is when charging with second charging current; Battery completely fills capacity can further be reduced; This moment, the current capacity that completely fills of said rechargeable battery further reduced; The difference of completely filling capacity and rated capacity when said rechargeable battery current greater than preset thresholding (as rated capacity 20%) time, show that this moment, rechargeable battery got into the rear end of life cycle, need further reduction charging current this moment.
That is to say; Said pattern judge parameter be said rechargeable battery recycle number of times, said chargeable electric core with the accumulated time that is higher than the predetermined voltage storage and the current capacity that completely fills of said rechargeable battery; Said at least two kinds of charge modes comprise first charge mode, second charge mode and the 3rd charge mode, and said charge mode according to definite this charging employing from said at least two kinds of charge modes of said pattern judgement parameter is specially:
In the current difference of completely filling capacity and rated capacity of said rechargeable battery less than preset thresholding; And said rechargeable battery recycle number of times less than the preset times thresholding; During less than the Preset Time thresholding, charge mode that this charging is adopted is first charge mode to said chargeable electric core with the accumulated time that is higher than predetermined voltage storage;

The difference of completely filling capacity and rated capacity said rechargeable battery current is during more than or equal to the preset capacity difference threshold, and charge mode that this charging is adopted is the 3rd charge mode;
First charging current of said first charge mode correspondence is greater than the second corresponding charging current of said second charge mode, and second charging current of said second charge mode correspondence is greater than the second corresponding charging current of said the 3rd charge mode.
In specific embodiment of the present invention; Charging current has only been considered in the front; But charging voltage also has certain influence to the life-span of rechargeable battery, reduces the life-span that charging voltage also helps prolonging rechargeable battery along with the reduction of completely filling capacity, therefore; When said rechargeable battery current completely filled capacity and is first capacity; Charging voltage during the charging of said rechargeable battery is first voltage, and said rechargeable battery current completely filled capacity for less than second capacity of said first capacity time, and the charging voltage during said rechargeable battery charging is less than said first voltage.
Among the embodiment before, only mention in each charging control how confirming charging voltage, but according to description before; The charge control method of the embodiment of the invention also can be a kind of changing method; Be applied in the electronic equipment, said electronic equipment has chargeable battery, and said rechargeable battery has first charge mode and second charge mode; Each charge mode is corresponding to different charging currents, and said charge control method is as shown in Figure 2 to be comprised:
