Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, the present invention is made below in conjunction with accompanying drawing into
One step it is described in detail, it is clear that the described embodiment only a part of embodiment of the present invention, rather than whole implementation
Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made
All other embodiment, belongs to the scope of protection of the invention.
The invention discloses a kind of charge protection method based on smart jack, embodiment as shown in figure 1, including：
For S100 when charging equipment is being charged on smart jack, collection smart jack is supplied to described to be charged set
Standby charging current；
S200 by the charging current of the charging equipment of collection with storage the charging equipment charging current
Memory curve is compared, judge the charging equipment whether charging complete, if so, into step S300；
S300 disconnects the electrical connection of smart jack and the charging equipment.
In the present embodiment, charging equipment, which is inserted on smart jack, to be charged, and to be charged set directly is supplied to smart jack
Standby electric current is sampled, and sampling here can be the current sample of a bit of time or adopting at certain time point
Sample, then the charging current memory curve of the charging equipment of the sample rate current with storing is contrasted, judge that this is to be charged
Equipment whether charging complete, if charging complete, then the electrical connection of socket and charging equipment is disconnected, so as to prevent from waiting filling
Electric equipment overcharges, and influences the battery life of charging equipment.
The charging process of general electronic/electrical gas equipment includes：Trickle charge (low pressure preliminary filling), constant-current charge, constant-voltage charge
And charging termination, but because voltage change can not detect in socket end the change of voltage, so the present invention only detects electricity
Rheology.
The charging process of general battery is divided into three phases.First stage is trickle charge, and battery starts in charging
Period electric current is bigger, now belongs to deep discharge, is particularly easy to produce heat energy, too high temperature directly influences battery
The quality of charging, so now passing through the charging of stable low current trickle fast and stable.The second is constant-current charge, that is, soon
Fast charging current, electric current are maintained at the invariable carry out large current charge of higher value, and voltage ramps, and reaches a magnitude of voltage
When, charging process-constant voltage charging phase of three phases is put into, this is that have a stable voltage, and it can make
Battery capacity gradually returns to state at the beginning, and now electric current slowly reduces, and when dropping to certain value and obtaining, maintains smaller
Electric current continues to charge to battery, in fact, now charges and has completed, and maintains smaller current to be overcharged to battery, for a long time
If influence whether the performance of battery.
According to this charge characteristic of battery, therefore the charging current memory curve of charging equipment can be obtained.Preferably
, can be by being carried out on the smart jack to the charging equipment before charging judgement is carried out to charging equipment
Once complete charging, each stage of the charging equipment charging is recorded, obtains and stores filling for the charging equipment
Electric current memory curve.
We are complete firstly the need of being carried out once on smart jack in certain electronic equipment with lithium battery by taking lithium battery as an example
Whole charging behavior, the electronic equipment can constantly gather the electric current that smart jack is supplied to the electronic equipment in charging process
Information.Current sample can be sampled according to curent change or time change samples, and the condition of curent change sampling is that electric current becomes
Change more than 5%；Time change refers to timing sampling, i.e., carries out current sample at regular intervals；Or take into account the two conditions
Sampled, can so meet both miss curent change, will not make sampled data excessive again.It is one as shown in Figure 2
The typical charging current memory curve of lithium battery.The charging current memory curve can be to be used as follow-up electronic equipment charging
Criterion.
Another embodiment of the present invention, as shown in figure 3, including：
For S100 when charging equipment is being charged on smart jack, collection smart jack is supplied to described to be charged set
Standby charging current；
S210 judges that the charging equipment is current according to the charging current memory curve of the charging equipment of storage
Charging stage；
S220 continues to charge when the charging equipment is in trickle charge stage or constant-current charging phase, and pre-
If the second time after return to step S100 gather the charging current of the charging equipment again；
S230 judges whether the charging current of the collection is less than when the charging equipment is in constant voltage charging phase
Or the minimum current value equal to constant voltage charging phase in the charging current memory curve, if so, into step S240, otherwise exist
After default 3rd time, into step S240；It is bent that default 3rd time is more than or equal to charging current memory
The time of constant-voltage phase in line；
S240 judges the charging equipment charging complete, into step S300.
S300 disconnects the electrical connection of smart jack and the charging equipment.
In the present embodiment, charging equipment can be supplied to the electric current of charging equipment in charging process to smart jack
Sampled, then the charging current memory curve of the charging equipment of the electric current of sampling with storing is compared, so as to
Know which charging stage the charging equipment is now arranged in, if in trickle or constant-current charging phase, then just
Continue to charge, returning again to step S100 after default second time continues to sample, and takes another look at its new progress stage.Compared with
Good, default second time here is (false more than or equal to the time of constant-current phase in the charging current memory curve
If the constant-current phase time is t2), because charging equipment is also in trickle or constant-current charging phase, then as t2 is latter yet
The situation of charging complete, the at most stage also in constant-voltage charge are not reaching to, in this way, the number of sampling can be so reduced,
But the judgement to charging equipment in time is not influenceed.And if charging equipment is in constant voltage charging phase, then just need
The charging equipment is determined whether either with or without being filled with, whether the electric current for seeing collection is minimum in charging current memory curve
Current value, if it does, then illustrating that charging has been completed, the electrical connection of socket and charging equipment can be disconnected, such as
Fruit no words, then at least in the charging current memory curve constant-voltage phase time (if the constant-voltage phase time is t3) it
Disconnect charging connection (now charge and completed) again afterwards.
Preferably, another embodiment of the present invention on the basis of above-described embodiment, is elaborated on how to be charged
What charging stage of equipment judged, specifically, as shown in figure 4, including：
For S100 when charging equipment is being charged on smart jack, collection smart jack is supplied to described to be charged set
Standby charging current；
S211 obtains the charging equipment and is according to the charging current memory curve of the charging equipment of storage
First reference current value in trickle stage；The charging equipment is in the second reference current value of constant-current phase, described to wait to fill
Electric equipment is in the minimum current value of constant-voltage phase；
S212 judges whether the charging current of collection is consistent with second reference current, if so, then entering step
S213, otherwise into step S214；
S213 judges that the charging equipment is in constant-current charging phase, into step S220；
S214 judges whether the charging current of collection is consistent with first reference current, if so, into step
S216, otherwise into step S215；
S215 judges that the charging equipment is in constant voltage charging phase, into step S230；
S216 gathers the charging current of the charging equipment after the default very first time, judge freshly harvested charging current
It is whether consistent with the preceding charging current once gathered, if so, into step S240, otherwise into step S213；It is described pre-
If the very first time be more than or equal to time in trickle stage in the charging current memory curve, and be less than the charging current
The time of constant-current phase in memory curve.
S220 continues to charge when the charging equipment is in trickle charge stage or constant-current charging phase, and pre-
If the second time after return to step S100 gather the charging current of the charging equipment again；
S230 judges whether the charging current of the collection is less than when the charging equipment is in constant voltage charging phase
Or the minimum current value equal to constant voltage charging phase in the charging current memory curve, if so, into step S240, otherwise exist
After default 3rd time, into step S240；It is bent that default 3rd time is more than or equal to charging current memory
The time of constant-voltage phase in line；
S240 judges the charging equipment charging complete, into step S300；
S300 disconnects the electrical connection of smart jack and the charging equipment.
In the present embodiment, according to charging current memory curve, the current reference value in each stage of charging can be obtained, then will
The electric current of collection is compared with each stage current reference value, so as to judge charging stage that charging equipment is presently in.From
As can be seen that constant-current charging phase, electric current is maximum and keeps constant, and the trickle charge stage protects substantially in charging current memory curve
Hold and charged in smaller current, constant voltage charging phase electric current slowly reduces, and smaller current charging is finally maintained at, therefore, if adopted
The size of current of collection substantially with the second reference current value of constant-current phase it is similar if (can be set a small error model
Enclose, can be considered consistent with the second reference current value in this error range), it can determine whether that the charging equipment fills in constant current
The electric stage, then charging has not been completed, it is also necessary to continue to charge, and electric current ratio can be gathered again after default second time
Compared with；If collection electric current it is both inconsistent with the first reference current, also with the second reference current it is inconsistent if, then substantially may be used
To judge that the charging equipment is in constant voltage charging phase, then now can be further by the sampled current value and constant-voltage phase
Minimum current value carry out referring to comparison.So as to judge whether charging complete, or after the time (t3) of constant-voltage phase again
Disconnect charging connection (now charge and completed).(the error if the size of the electric current gathered is consistent with the first reference current
In the range of), then two kinds of possibility are there is now, and it is probably that also kind is probably in constant pressure in the trickle stage that one kind, which is,
Stage, then now just need further to acquire, because trickle stage current is basically unchanged, and last electric current in constant-voltage phase
Also maintain smaller current constant substantially, therefore, electric current can be gathered again after the default very first time and judged, here first
Time is at least greater than or the time (trickle phases-time is t1) equal to the trickle charge stage, here default first when
Between meet：t2>The default very first time>t1；Like this, if charging equipment is in the trickle stage at that time, then during t1
Between after, it should arrived constant-current phase, then the electric current of second collection certainly and collection for the first time electric current it is inconsistent, change width
Degree also can be bigger, therefore can combine second of size of current gathered to judge the charging equipment current charging stage
If the electric current of second collection is larger, reached the second reference current value, then illustrate be before in the trickle stage, but
Constant-current phase is reached after the default very first time, if the electric current and the preceding electric current once gathered of second of collection are basic
Almost, if having no change, then illustrate that charging equipment has been in the last low current part of constant voltage charging phase,
It is substantially in the state overcharged, then it may determine that the charging equipment charging complete, can disconnect charging connection.
Another embodiment of the present invention, on the basis of any of the above-described embodiment, judging charging complete or be disconnected to fill

The smart jack embodiment of the present invention is corresponding with the embodiment of the method for the present invention, the technology of the inventive method embodiment
Details is equally applicable to the smart jack embodiment of the present invention, is repeated to reduce, no longer superfluous to chat.
The smart jack of the present invention has two mode of operations, and one is charge protection pattern, and one is common Working mould
Formula, smart jack can carry out charge control and protection under charge protection pattern to the equipment to be charged.Commonly working
Under pattern as common socket, the equipment to insertion is powered.Long-press button can be set to enter charge protection pattern, in addition,
The smart jack of the present invention can also control multiple equipment to charge, and each jack controls a equipment charge.
Another embodiment of smart jack of the present invention, the smart jack are an insert row, and the insert row has multiple jacks, each to insert
Hole has different buttons to be controlled, and this button can enter the curve memory pattern of jack, schematic diagram such as Fig. 8 by long-press
It is shown.
The charging process of general charging equipment includes：Trickle charge (low pressure preliminary filling), constant-current charge, constant-voltage charge and fill
Electricity terminates, but because voltage change insert row can not detect, so the present embodiment only detects curent change.The present embodiment
Intelligent socket is by first remembering charging current curve, comparing charging curve afterwards, realize the insert row of intelligent power down function.
Completely charging behavior is carried out once firstly the need of charging equipment, allows sub- jack to carry out the memory of charging curve；It is long
Flashed by sub- jack button to sub- jack press key lamp, then into the curve memory pattern of sub- jack, at this moment plug to have already passed through and fill
The charging equipment of electric discharge is divided to be charged, curve memory module start recording charging curve；After the completion of to be charged, user press by
Key exits memory pattern, then completes curve memory；During the follow-up equipment charge, meeting is according to the charging curve recorded and in real time
Charging current curve contrasts, to confirm at present in what stage of charging, so can also memory based curve, exclude one
A little abnormal charging behaviors, such as electric current are excessive.
Specifically, the Intelligent socket includes charging curve memory module (equivalent to mnemon), charging curve compares
Module (equivalent to control unit), its role are as follows：
(1) charging current curve memory module
Curve memory pattern is entered by the sub- jack button of long-press, and into after this pattern, insert row can be according to electric current
Change and time change sample, and the condition that curent change samples is curent change more than 5%；Time change refers to that timing is adopted
Sample, i.e., carry out current sample at regular intervals, and two such condition can meet both miss curent change, will not make again
Sampled data is excessive；Charging current memory curve is as shown in Figure 2.
(2) charging curve comparing module
From charging curve above, it can be appreciated that the minimum current and maximum current of charging be it is how many, so we
Can does the sampling of a period of time to current flow, to confirm whether charging is completed
If electric current is the high current stage, charging unfinished, continue to charge；
