Description
Technical field
The present invention relates to charger field, adjusts in particular to a kind of charging current method of adjustment, charging current
Device and charger.
Background technology
With the development of electronics technology, charger, especially intelligent movable charger are applied in our life
More and more extensive, the life impact on us is more and more deep.But widely using along with intelligent movable charger, move
Dynamic intelligent charge equipment also highlights a more serious problem in terminal unit (mobile phone, panel computer) charging process.
For example, hot in charging process cause charging effective power to reduce, cause charger functional reliability to reduce, excessive heating is led
Cause charger service life to shorten, bring poor experience effect to cause customer complaint charger to user.
It is therefore proposed that a kind of method that can adjust charging current applies solution terminal in charging device and charger
The problem that equipment causes effective power to waste because heating of charging soon is hot, (intelligence charges soon to reach raising charger
Device) reliability that works, the effect for extending its service life and lifting Consumer's Experience becomes technical problem urgently to be resolved hurrily.
Content of the invention
It is contemplated that at least solving one of technical problem present in prior art or correlation technique.
For this purpose, it is an object of the present invention to proposing a kind of charging current method of adjustment.
Further object is that proposing a kind of charging current adjusting apparatus.
Another object of the present invention is to propose a kind of charger.
For achieving the above object, a kind of embodiment according to the first aspect of the invention, it is proposed that charging current adjustment side
Method, for charger, including：The in-fighting power of terminal to be filled is detected, is compared with predetermined in-fighting power；If in-fighting power is little
In or be equal to the predetermined in-fighting power, then be charged using maximum charging current；If in-fighting power is predetermined interior more than described
Wasted work rate, then reduce charging current.
In this embodiment it is possible to the predetermined in-fighting power P 0 of user's acceptable is set in terminal to be filled, by detection
The real-time in-fighting power P of terminal to be filled, compares the size of the real-time in-fighting power P and predetermined in-fighting power P 0 for detecting terminal to be filled
Make corresponding process.Wherein, if P be less than or equal to P0, charger will treat fill terminal provide maximum charging current carry out
Charge；If P is more than P0, charger is treated to fill terminal and provide and is charged less than the electric current of maximum charging current.By above-mentioned
Method can cause charger to be consistently less than or wait treating the in-fighting power that fills terminal to be filled when terminal is charged process
In predetermined in-fighting power, thus can reduce generation charger causes electricity heating, hot causes effective power unrestrained because filling soon
The probability that takes, reaches the reliability for improving charger work, extends its service life and lift the effect of Consumer's Experience.
Wherein, it will be appreciated by those skilled in the art that terminal to be filled can be mobile phone, panel computer, notebook computer or
Other electronic equipments that need to charge, charger can be portable power source, fixing charger,
According to one embodiment of present invention, it is proposed that before detecting the in-fighting power of terminal to be filled, also include：Detection is treated
The real-time temperature values of terminal are filled, is compared with preferred temperature value；If real-time temperature values are less than or equal to preferred temperature value, make
Treated with maximum charging current and fill terminal and be charged；If real-time temperature values are more than preferred temperature value, start to detect interior wasted work
Rate.
In this embodiment, the in-fighting power of terminal to be filled is difficult directly to check and draws, can pass through indirect otherwise
Draw.Before in the example, proposition detects the real-time in-fighting power of terminal to be filled, can detect and the real-time internal power of terminal to be filled
The real-time temperature values of value terminal to be filled correspondingly, are compared with preferred temperature value.For example：Arrange in terminal to be filled and expect
(temperature value T0, usual human body acceptable ideal temperature is less than 36 degrees Celsius to temperature value T0, according to using scene and environment T0
Value can also be defined by user oneself), by the real-time temperature values T of terminal to be filled is detected, compare and detect the real-time of terminal to be filled
The size of temperature value T and preferred temperature value T0 makes corresponding process.Wherein, if T is less than or equal to T0, charger is treated and is filled
Terminal provides maximum charging current and is charged；If T is more than T0, charger is treated and fills terminal offer less than maximum charging current
Electric current be charged.The real-time temperature values of the real-time internal power value of terminal to be filled terminal to be filled correspondingly, are being difficult directly
In the case of detecting terminal internal power to be filled, by detecting the real-time of terminal to be filled before the in-fighting power of terminal to be filled is detected

And detection scheme is simple, easily implement, error is less.
According to one embodiment of present invention, it is proposed that preferred temperature value is configured according to their needs by user；Its
In, acquiescence preferred temperature value is 36 degrees Celsius.
In this embodiment, usual human body acceptable ideal temperature is less than 36 degrees Celsius, and therefore terminal to be filled is arranged
Preferred temperature value T0 default value be 36 degrees Celsius, by the setting of this more hommization, can reduce due in charging process
The too high terminal to be filled for causing of temperature is affixed the unexpected scald of generation with skin, so as to reduce the probability of user experience；Additionally,
Preferred temperature value T0 that terminal to be filled is arranged can be according to being defined by user oneself using scene and environment, in different scenes and ring
Different preferred temperature values T0 can be arranged according to practical situation under border, for example：In winter, mobile phone is it sometimes appear that temperature is too low
Cause the situation of automatic shutdown, the speed of electricity punching is also slow, now can by the height of preferred temperature value setting a little for example
(40 degrees Celsius), using the high preferred temperature value of a bit, on the one hand can accelerate charge rate, on the other hand can also provide heat
Amount, resists external environmental interference, it is ensured that the normal operation of mobile phone, the method can be applicable to different scenes, and the adaptation of environment
Property is stronger.

Draw.Before proposing the real-time in-fighting power for detecting terminal to be filled in the example, can pass through the detection of temperature comparing unit 206 with
The real-time temperature values of the real-time internal power value of terminal to be filled terminal to be filled correspondingly, are compared with preferred temperature value.For example：
Arrange in terminal to be filled and expect that (temperature value T0, usual human body acceptable ideal temperature is less than 36 degrees Celsius, root to temperature value T0
Can also be defined by user oneself according to scene and environment T0 value is used), by detecting the real-time temperature values T of terminal to be filled, compare
Detect that the real-time temperature values T of terminal to be filled and the size of preferred temperature value T0 make corresponding process.Wherein, if T is less than or waits
In T0, charger treat fill terminal provide maximum charging current be charged；If T is more than T0, charger is treated and fills terminal
Offer is charged less than the electric current of maximum charging current.The reality of the real-time internal power value of terminal to be filled terminal to be filled correspondingly
