According to the quick charging method, the constant voltage charging time can be prolonged to the greatest degree, so that the whole charging time is shortened.
Description
Technical field
The present invention relates to rechargeable battery, be specifically related to a kind of fast charge method, especially be applied in the handheld device.
Background technology
Now, charging flow can be divided into trickle, constant current and and constant voltage charge stage.According to existing charging flow, after system detects cell voltage and reaches the constant voltage charge electrical voltage point, immediately will get into constant voltage charge, and maintain constant-voltage phase, satisfy the back complete charge until cut-off condition.When large current charge, because system's virtual height is a lot, the time in constant current charge stage is very short, causes constant voltage charging time long, has also just caused the whole charging interval long.At present also do not avoid the charging method of this problem or such method to be disclosed.
Summary of the invention
The technical issues that need to address of the present invention are, how a kind of fast charge method is provided, and can prolong the time of constant current charge to greatest extent, thereby shorten the whole charging interval.
Technical problem of the present invention solves like this: make up a kind of fast charge method, utilize charging chip (IC) and a plurality of constant current charge to preset gear, its constant current charge process may further comprise the steps:
A divides the many gears of ladder that battery is carried out repeatedly constant current charge, the different separately preset gears of each constant current charge correspondence;
B when each constant current charge when being recharged the pond and reaching constant voltage charge voltage, the current value of turning constant current charge next time down is until the preset gear of minimum.
According to fast charge method provided by the invention, said preset gear is 3～10.
According to fast charge method provided by the invention, initial constant current charge electric current is the maximum preset gear less than actual connection adaptor load capacity in the said constant current charge process.
According to fast charge method provided by the invention, the difference of said preset gear is or the plural charging interval of charging IC.
According to fast charge method provided by the invention, the preset gear of said minimum is supported current value more than or equal to the minimum of charging IC.
According to fast charge method provided by the invention, this method also is included in the trickle charge before the said constant current charge process.
According to fast charge method provided by the invention, this method also is included in the constant voltage charge after the said constant current charge process.
Fast charge method provided by the invention has utilized battery charge virtual height and the adjustable characteristic of charging IC electric current, has the following advantages than prior art:
1, prolongs the time of constant current charge to greatest extent;
2, shortened the time of whole charging greatly.
Description of drawings
Further the present invention is elaborated below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the software flow sketch map of the battery charge handling procedure of the preferred specific embodiment smart mobile phone of the present invention;
Fig. 2 is the battery charge principle schematic of the preferred specific embodiment smart mobile phone of the present invention.
Embodiment
At first, the principle of the invention and key are described:
1, divide ladder to carry out the repeatedly alternative traditional only constant current charge of a fixed current value of constant current charge of many gears, every ladder correspondence is gear separately, and each gear current value descends by ladder;
2, initial constant current charge electric current is selected according to the adapter load capacity, select less than and near its current value;
3, each constant current charge electric current gear of selecting all can be charged to constant current charge always and finish, and can send interruption this moment, and get into the constant voltage charge stage;
4, after CPU receives interruption (got into the constant voltage charge stage this moment), the constant current charge electric current of a smaller gear of software setting;
5, the selectable gear of the charging chip that has (IC) is a lot, and each gear is very little (such as 50mA) at interval, and minimum current gear very little (possibly have only 100-200mA).Therefore, can not continuous carrying out in turn from big to small, may total thought is still turned electric current down exactly, reduce the voltage of battery virtual height at a distance from several gears, let it get back to the constant current charge stage;
6, also not necessarily can choose that minimum gear.Such as the charging current of maximum 1A, just may choose behind the 400mA can be toward not reduced, even minimum also have 200mA, the such gear of 100mA.
The second, concrete realization of the present invention is described in conjunction with the preferred embodiments:
As shown in Figure 1, the battery charge handling procedure of the preferred specific embodiment smart mobile phone of the present invention, preset many gears constant current charge current value from big to small comprises following concrete steps:
301) charger is inserted in detection and judgement;
302) mobile phone carries out trickle charge with preset trickle-charge current;
303) mobile phone according to the adapter load capacity select near but the constant current charge electric current gear that is no more than it carries out constant current charge;
304) after constant current charge finished, charging module sent interruption, got into the constant voltage charge stage;
305) CPU detects interruption, is directly to select next gear to carry out constant current charge, returns step 304 again), if there is not next gear then to get into next step;
306) get into the constant voltage charge pattern, end up to charging.
As shown in Figure 2, in this preferred specific embodiment, adopt the constant voltage charge current value of four gears, it is too short to have overcome the constant current charge time that system's virtual height reason causes so well.Its charging process comprises constant current charge four times after trickle charge, corresponding operation principle is:
401) after the n time (1≤n≤4) constant current charge finishes, charging IC can send the interrupt notification processor, and the IC that charges simultaneously gets into the constant voltage charge pattern automatically.This moment has been owing to just got into the constant voltage charge pattern, and is smaller when charging current can be than constant current charge.Suppose that this moment, electric current was A
402) processor detects and has no progeny in above, and (B＜A), the actual act of corresponding processor can be reduced to: directly select next gear control charging IC to carry out constant current charge to turn in the ladder gear current value charging current down near electric current A electric current B;
403) because electric current diminishes, cell voltage can fall back to below the constant voltage charge voltage.Therefore get into the constant current charge stage again;
404) etc. finish to constant current charge, when getting into the constant voltage charge pattern, can report and interrupt giving processor with the B current charges;
405) below with regard to repeating step 401), 402), 403) also accomplish constant current charge until minimum gear current value;
406) get into the constant voltage charge pattern, end up to charging.
At last, the above is merely preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
