Section is not intended to restrictions, but as just the basis of claim and representative basis be used to instructing those skilled in the art with
Substantially any appropriate detailed construction diversely uses the disclosure.
This specification can be used phrase " in one embodiment ", " in another embodiment ", " in another embodiment
In " or " in other embodiments ", it can be referred to according to one or more of identical or different embodiment of the disclosure.
As shown in Figure 1, the present invention discloses a kind of charging method, applied in the electronic equipment with rechargeable battery, it is somebody's turn to do
Rechargeable battery at least has CV charge modes.Specifically, charging method of the invention includes：
Judge whether battery enters CV charge modes, if so, charged with specific charge mode, the specific charging mould
Formula is：
The current goal voltage of preset battery is determined, that is, what is set in systems is used to control to adjust working as battery
The target voltage of preceding charging voltage provides control benchmark with the current charging voltage for battery, and then makes system can be according to the mesh
It marks voltage and adjusts charging current；
Detect the current charging voltage of battery；
Judge whether current charging voltage is less than preset initial target voltage (that is, the target voltage of setting for the first time, is somebody's turn to do
Target voltage is regarded as optimum charging voltage), if being less than, current goal voltage is increased, to increase current charging voltage, from
And achieve the effect that the current charging current of raising, that is, the charging current of battery CV charging stages can be improved, enable battery
Shorten the charging time.When user is eager to charge for electronic equipment, charged the battery using the charging method in the application,
The needs of user can be met, improve user experience.
Further, if judging, battery does not enter CV charge modes, continues to charge with current charge mode.For example,
Battery is charged before entering CV charge modes for CC charge modes, then battery continuation with CC charge modes.
If as shown in Fig. 2, judging that the current charging voltage of battery is more than preset initial target voltage, current mesh is reduced
Voltage is marked, to reduce current charging voltage, current charging voltage is made to be equal to initial target voltage.Because to current goal voltage
After being pressurizeed, it may result in current charging voltage and exceeded initial target voltage, in order to avoid leading to charging current mistake
Greatly, make to be difficult to control, harmful effect probably is caused to battery, it is therefore desirable to be more than in the current charging voltage for judging battery preset
After initial target voltage, current target voltage is depressured in time, that is, being that the target voltage after pressurization is dropped
Pressure.Until current charging voltage declines, and gradually approaches initial target voltage, until equal to until initial target voltage, stop
Only continue to reduce current goal voltage, and keep current target voltage, system is made to be controlled based on the target voltage currently
Charging voltage and charging current, until battery charging terminates.
Continuing with shown in Fig. 2, in the current charging voltage for detecting battery, following steps are specifically included：
With the current charging voltage of preset set time threshold test battery.It is namely intermittent to detect working as battery
Preceding charging voltage, the adjacent interval time detected twice can sets itselfs, such as set 5 seconds, 10 seconds etc. according to actual needs
Deng.
Further, the current goal voltage for increasing battery is specially with preset first fixed value raising current goal electricity
Pressure；
The current goal voltage for reducing battery is specially to reduce current goal voltage with preset second fixed value.It is preset
First fixed value can be equal with the second fixed value, can not also wait, and can specifically be decided according to the actual requirements, such as first is fixed
Value is set as 16mv, 14mv, 20mv etc., and similarly, the second fixed value may be alternatively provided as 16mv, 14mv, 20mv etc..
Preferably due to the battery core voltage and external charging voltage of battery are distinguishing, because battery has internal resistance,
Also have resistance value at charging interface, thus cause external charging voltage can a little higher than battery core voltage, for avoid pressurization time interval compared with
It is short, there are external charging voltage spikes so that external charging voltage is more than the specified maximum charging voltage of battery, and battery is made
Into influence, the control method in the present embodiment is gone back after judging whether current charging voltage is less than preset initial target voltage
Including step：
Judge current charging voltage whether and meanwhile less than the maximum charging voltage of battery, increase current mesh if entering less than if
The step of marking voltage；Wherein maximum charging voltage is more than target voltage.
