Description
Technical field
A kind of charger is the utility model is related to, particularly a kind of Intelligent Dynamic shows the charger of charge information.
Background technology
An indispensable component of the machine charger as mobile phone, the quality of its performance, it will directly influence us
The normal use of mobile phone, so the imagination of the effect of charger for mobile phone out of us.Present charger for mobile phone, on the one hand lack
Intellectuality, charge function is can be only done, without alarm and necessary display function；On the other hand this charger is to battery
There is no corresponding safeguard measure, fallen sharply in the life-span of battery of mobile phone yet.In order to solve the problems, such as that this is a series of, it would be desirable to one
The charger for mobile phone of kind intelligence.
The product quality of some chargers currently on the market can not meet the requirement of people, and quality cannot be guaranteed, and
Potential safety hazard also be present.A series of problems, such as quality problems of charger, safety problem, directly affects the normal use of mobile phone, this
Also substantially reduce the life-span of battery of mobile phone, ultimately resulting in the stand-by time of mobile phone becomes shorter and shorter.Particularly safety problem
Particularly important, the report that mobile phone explodes in charging process is countless, largely relevant with charger for mobile phone, this kind of
The solution of problem is very urgent, once occur surprisingly, unthinkable harm will being caused to us.Present charger for mobile phone
Two kinds of charging methods are mostly used, first is exactly constant current rapid charging, and another kind is exactly voltage ratio compared with mise-a-la-masse method.Actually
The charging method of two kinds of charging methods or comparative maturity, but they all can have influence on battery of mobile phone in different degree
Life-span.With the appearance of single-chip microcomputer and the development of singlechip technology, this also causes charger for mobile phone to have new developing direction,
Just it is towards intelligent direction development.
The charging method that charger for mobile phone currently on the market uses mostly is the rapid charging of high current, this charging
The maximum harm of method is exactly after battery is full of, if stopping charging not in time can make it that battery is hot, is so easy to
Damage battery.Certainly also there is cost than relatively low charger, they are voltage comparison methods using charging method, this charging method
It can prevent from overcharging, when battery is charged to 95% completely, high current fast charge will be stopped, then use low current trickle to mend
Charging.Generally for making battery fully charged, it is easy to cause to overcharge.It is embodied in：Some chargers fill in battery
Man Shihui continues hot.The regular appearance of battery overcharges or during charge less, can have a strong impact on the use of people, be embodied in：
The cell phone standby time becomes shorter and shorter.Research shows the service life of lithium battery, time and charge maintenance process is intended for single use
There are close ties with service condition.The fine or not standard for weighing a charger is exactly to see that the charger can be in the short time
It is interior to be full of battery, and corresponding protective effect can be played to battery, and repair due to the improper use of battery and cause
Memory effect.Traditional charger does not possess this protection and repair function.
Utility model content
To solve the above problems, the application provides the charger that a kind of Intelligent Dynamic shows charge information.
A kind of Intelligent Dynamic shows the charger of charge information, it is characterised in that：Including LCDs, data processing list
Member, temperature sensor, charging chip, the data processing unit is respectively at temperature sensor, LCDs and charging chip
Connection, the charging voltage and charging current that the data processing unit exports to charging chip are to sample, and dynamic in real time

It is preferred that the charging chip is MAX1898.
It is preferred that the data processing unit is a kind of single-chip microcomputer, the single-chip microcomputer is STC15W401AS QFN28.
Intelligent charger is exactly to meet that the needs of user is designed.Intelligent charger can be controlled to charging process
System, can not only be protected in charging process to battery, and can prevent overvoltage and control charging temperature.This intelligence
Energy charger is using data processing unit as control core, and it can detect the voltage signal change when battery charges saturation, so
Afterwards by the information transmission of complete charge to charging chip, accurately complete charge process.Except data processing unit, this intelligence
Charger also has an important part：Charging chip, this charger chip can realize the control to charging process, then add
Upper data processing unit control function, such as time control, buzzing alarm, power remove, temperature control and liquid crystal display control
Deng, it becomes possible to realize intelligent charging.Power Electronic Technique develops rapidly so that chip volume is less and less, the collection of circuit
Cheng Hua, this make it that intelligent charger mass produces.
The charger of new intelligent charger, the current charging voltage to charge of display immediately after being connected on mobile phone
With charging current and charger current operating temperature.Solves the visualization problem of charging process, product is attractive in appearance, and practicality is more
Hommization.Product reliability is high, simple to operate, and more security and versatility, represents following charging.
Increase temperature detection can detect the temperature of charger in charging process, play a part of reminding user, make user
The environment that suitably charges can be selected, prevents influence charging effect too high or too low for temperature, ensures the shelf life of battery, simultaneously
Or the USB desired temperatures detection instrument of a both artistic and practical mini types, in current life, user can examine whenever and wherever possible
Survey the temperature of oneself surrounding environment.
Product reliability is high, simple to operate, and more security and versatility, represents following charger development side
To.
