Background technology
At present, handheld device is as mobile phone, MPC, palmtop PC etc., and the main lithium battery that uses, as power supply energy, mainly adopts traditional charging modes that such as MTK, high pass and exterior I C realize, namely a battery is by preliminary filling, constant current, constant voltage process, makes it be full of electricity.This scheme needs solution supplier to set the demand parameters such as clear and definite charging current, charge cutoff voltage.Like this, after the battery of a fixed capacity dispatches from the factory, its entire charge cycle, electric current and charging interval are all determined, the lithium battery of a conventional scheme process like this under the demand of nowadays intelligent machine big current, large power consumption, the tradition life-span all only have 1 year less than.
Segmentation scheme provider proposes to fill technology soon, uses 1.5A, 2A even charging current of 3A to charge the battery, and can shorten the time of battery charging like this thus improve Consumer's Experience.But because the life-span of lithium battery itself and the size of charging current are inversely proportional to, therefore battery life can have very large decline; Or fill scheme soon to take into account, the technique of battery needs higher requirement, and cost and material requirements are also higher.
Summary of the invention
For the problem that current smart machine battery is limited; the present invention proposes a kind of battery charging schedule of smart machine; do not relate to hardware modification, farthest can protect battery under the prerequisite not affecting Consumer's Experience, finally can realize extending battery.
Solution of the present invention is as follows:
A battery charging module for smart machine, comprises
Unit is opened in charging, for forming down trigger at charger for during electrical connection smart machine, opens charge mode;
Timing differentiates processing unit, for judging whether current point in time crosses setting-up time point, if so, then continues to judge whether there is further operation within the setting stand-by period; If not, then charging interval customization window is jumped at UI interface;
Shallowly fill mode unit, for when in the described setting stand-by period without when operating further, charge according to the shallow mold filling formula lower than standard charging current; When have in the described setting stand-by period operate further time, UI interface is also jumped into the charging interval and is customized window, and according to user, at UI interface, self-defining charging interval calculates charging current and charges;
Shallowly fill termination unit, for whether corresponding to shallow mode detection cell voltage, the electric current of filling to exceed setting threshold, if exceed setting threshold, charge closing path.
Based on above scheme, the present invention also does following optimization further:
The battery charging module of this smart machine also has additional charger identifying processing unit, for when opening described charge mode, first judges whether charger type is standard charger, if not, then charges according to standard charging current; If so, just enter described timing and differentiate processing unit.
The battery charging module of this smart machine also has additional the self-defined activation unit in UI interface, for reopening charging interval customization window according to user in the operation at UI interface under shallow mold filling formula.
The above-mentioned charging interval customizes the form that window can adopt charging interval progress bar, if To represents that an exhausted cell is full of the charging interval required for electricity with standard charging current Io; Tx represents terminal use's self-defining charging interval; The length that To converts interface charging interval progress bar to is L0, and user-defined charging interval display length bar is Lx, then:
Ix＝Lx/L0*Io；
Tx＝Lx/L0*To。
According to rechargeable standard conventional at present, above-mentioned standard charging current is chosen to be 400mA, and the charging current of shallow mold filling formula is defined as 200mA.The setting threshold of cell voltage is 4.2V, and the setting threshold of battery current is 100mA.
According to terminal operation and the habits and customs of most of user, the above-mentioned setting stand-by period can be decided to be 5 minutes, above-mentioned setting-up time point is decided to be 23 points.
The present invention has following technique effect:
Under normal circumstances, a lot of user can select to go to charge the phone when having a rest at night, because charging in evening is from 12 .-8 points; there is the time of 8 hours; after current scheme is all battery charging complete, with regard to charge closing flow process, reach the object to battery protection.But actual evening is when charging, although be filled with, people also can not go to pull out charger, so the charging in evening can use low current charge to reach the object of maintenance battery completely; Mobile phone can control charging current at about 200mA, and this mode can make actual battery at least extend more than one times.And when terminal use in dead battery but emergency uses electricity time, then with maximum current go charging, to shorten the charging interval, to promote Consumer's Experience.
Therefore, adopt the solution of the present invention, user can the self-defined charging interval, or software oneself judges the charging interval, thus farthest can protect battery under the prerequisite not affecting Consumer's Experience, while charging flow can be made to become hommization more.
Accompanying drawing explanation
Fig. 1 is the algorithm flow chart of one embodiment of the invention.
Embodiment
This intelligent charge scheme mainly comprises two aspects;
On the one hand, handheld device is if mobile phone is after charger inserts, and mobile phone is developed special charging and controlled option on UI interface or on menu, can exist to reach cross-platform, across the effect of software version with the form of apk.When apk opens (figure punctuate is opened), interface display charging interval bar, this figure indicates special driving interface direct and connects managing mobile phone charhing unit, therefore when terminal use is when operating charging interval bar, just can find out the charging interval needing to arrange intuitively, drive and convert the charging interval to concrete charging current by algorithm in code;
To represents that an exhausted cell is full of the charging interval required for electricity with charging current Io; Tx represents terminal use's self-defining charging interval; The length that To converts interface charging interval progress bar to is L0, and user-defined charging interval display length bar is Lx.Then:
Ix＝Lx/L0*Io；
Tx＝Lx/L0*To；
Drive in code and determining terminal use to charging interval bar generation operation, then by the conversion of algorithm, by concrete charging current to calculate the global variable that income value is delivered to register corresponding to charging current or coupling, thus mobile phone charges with the charging current set, so just can reach when user needs quick charge time, then charge with maximum current, when terminal use no hurry charging time, shallow mold filling formula then can be used to charge to mobile phone, thus the object reached battery maintenance, be charging flow hommization more simultaneously.
On the other hand, the state that cell phone intelligent judges current end user whether boost charge, thus design itself charging current, on the basis of the first step, suppose the unmanned words that charged interface is operated, interface is automatically exited in interface after 5-10s, when synchronous mobile phone self is read, judge the time whether after 23 o'clock, mobile phone charges with the 600mA of acquiescence, if then spend 5 minutes, mobile phone does not carry out any operation, then mobile phone is judged as that terminal use has a rest, and now carries out shallow mold filling formula, to maintain battery; Certain hypothesis just this 5 minutes users does not operate, and client needs quick charge again, then the apk that charges can open at any time, cancels the intelligent charge state of software default.
