Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
Embodiment one
For realizing the charging interval shortening electronic equipment when ensureing safety as far as possible, and reach optimum charging effect, a kind of charging method that the embodiment of the present invention one provides, as shown in Figure 1, the method mainly comprises as far as possible:
Step 101, when electronic equipment is connected with charger, detects the type of the charger connected.
The type detection method of charger has multiple, as: the type detecting charger according to the output signal of charger, or the pin voltage according to charger interface detects type of charger etc.The embodiment of the present invention does not limit the type detection method of charger, and in practical application, every detection method that electronic equipment can be made to obtain charger type all should belong to the protection range of the embodiment of the present invention.
Charger type in practical application also has multiple, as: alternating current adapter (AC adapter, Alternating Current adapter), USB special charging port (USB-DCP, UniversalSerial Bus-Dedicated Charging Port), universal serial bus standard downlink port (USB-SDP, Universal Serial Bus-Standard Downstream Port) etc., the embodiment of the present invention does not enumerate.
Wherein, the USB port that electronic equipment is connected to charger has 5 lead-foot-lines, and this is 5 with including D+ data wire pin (also claiming data wire positive pole) and D-data wire pin (also title data wire negative pole) in lead-foot-line; If electronic equipment detects D+ and D-short circuit, then judge that the charger type connected is USB-DCP, if D+ and D-not short circuit detected and D+ and D-have voltage, then judge that the charger type connected is USB-SDP, if D+ and D-not short circuit detected and no-voltage on D+ and D-, then judge that the charger type connected is unknown (i.e. charger type the unknown).
Step 102, is set as interim upper limit charging current by the first foundation charging current corresponding with the type of charger preset, and the charging current controlling charger does not exceed interim upper limit charging current.
In the embodiment of the present invention, pre-set the first foundation charging current of corresponding different charger type, wherein, the first foundation charging current of corresponding different charger type can be not identical, or, the first foundation charging current of corresponding different charger type also can part identical or all identical.That is, the mapping relations of charger type and first foundation charging current value are preset with in electronic equipment, save the value of the first foundation charging current corresponding with the charger type that each is preset in these mapping relations, the value of the first foundation charging current of corresponding different charger types can be the same or different.
Electronic equipment is after detecting the charger type obtaining current connection, by searching described mapping relations, can obtain and the first foundation charging current corresponding to obtained charger type, thus the first foundation charging current of acquisition is set as current interim upper limit charging current, and the charging current controlling charger does not exceed the interim upper limit charging current of current setting.As: suppose that the first foundation charging current that electronic equipment obtains is 500mA (milliampere), then electronic equipment can control to flow into the charging current of electronic equipment and do not exceed 500mA, electronic equipment can by the control of charge integrated circuit (IC, Integrated Circuit) realization to inflow current of its inside.
Step 103, step-type current boost is carried out on the basis of first foundation charging current, control the charging current of charger do not exceed each stepping promote after interim upper limit charging current; Until when interim upper limit charging current reaches the first predetermined current threshold, the charging current controlling charger does not exceed the first predetermined current threshold.
Wherein, so-called step-type current boost refers to, the basis of first foundation charging current is carried out the current boost of same magnitude repeatedly (or claiming step value) or different amplitude, such as: first foundation charging current is 500mA, the first predetermined current threshold is 1000mA, on the basis of 500mA, each amplitude promoted is 100mA, so needs can reach 1000mA through the current boost of 5 times on the basis of 500mA.
Interim upper limit charging current after the so-called charging current controlling charger does not exceed the lifting of each stepping refers to, control to flow into the charging current of electronic equipment be no more than each stepping promote after interim upper limit charging current, such as: on the basis of first foundation charging current 500mA, interim upper limit charging current after first time promotes is 600mA, and the charging current so now controlling to flow into electronic equipment is no more than 600mA; Follow-up interim upper limit charging current on the basis of 600mA after lifting becomes 700mA, and the charging current so now controlling to flow into electronic equipment is no more than 700mA; The rest may be inferred.
When interim upper limit charging current reaches the first predetermined current threshold 1000mA, the charging current now controlling to flow into electronic equipment is no more than 1000mA.
That is, along with the stepping of interim upper limit charging current promotes, electronic equipment allows the upper limit of the charging current flowed into also to promote, to reach the object of the charging current of step-type control charger thereupon.

Through the lifting of described interim upper limit charging current at least one times, described interim upper limit charging current is made to reach the first predetermined current threshold.
Wherein, described first condition can be: detect the CV of gained higher than the voltage threshold preset, and the CC detecting gained reaches current interim upper limit charging current.Described voltage threshold can set according to actual needs in (the hardware parameter requirement etc. as distinct electronic apparatuses self), as: between 4.5V ~ 4.7V, select voltage threshold, preferably, voltage threshold is set as 4.6V.Requiring that the CV detecting gained is higher than the voltage threshold preset, is in order to ensure the requirement of charging voltage symbol.Requiring that the CC detecting gained reaches current interim upper limit charging current, is, when rising to described current interim upper limit charging current in order to ensure having the ability at CC, just carry out the further lifting of interim upper limit charging current.
Electronic equipment is after each lifting obtains new interim upper limit charging current, CV and CC detecting charger is continued in capital, if CV and CC detecting gained meets first condition, then continue to promote current interim upper limit charging current, if detect CV and CC of gained not meet first condition, then keep current interim upper limit charging current constant; So, until described interim upper limit charging current reaches the first predetermined current threshold.This first current threshold according to actual needs (hardware parameter as distinct electronic apparatuses self requires or the requirement such as coefficient of safety) sets, as: between 500mA-1200mA, select the first current threshold, preferential, the first current threshold is set as 800mA.
In one embodiment, described method also comprises: when detecting the type of charger of connection, obtain the second basic charging current, described second basic charging current is set as interim upper limit charging current, and the charging current controlling described charger does not exceed described interim upper limit charging current;
