With the fast charging system of high pressure, with versatility higher.
Second embodiment
First embodiment above has carried out simple introduction to the voltage control method of charging inlet of the invention, below this reality
Applying example will be described further with reference to accompanying drawing and concrete application scene to it.
As shown in Fig. 2 the voltage control method of the charging inlet of the embodiment of the present invention specifically includes following steps：
Step 201：Obtain at least three current values of charging inlet output.
Wherein, above three current value is that mobile terminal is being detected after charging inlet temperature exceedes predetermined threshold value to charging
When interface carries out default drawing load, charging inlet is through drawing the current value for being loaded onto default pulling load current and persistently being exported after Preset Time.
Here obtaining at least three current values is worth being at least to draw charging inlet twice load, i.e. current value at least to occur to become twice
Change.Mobile terminal carries out output electric current measure in the output end of charger, is set when being exceeded by NTC resistance detections to port temperature
When determining threshold value, the VBUS electric currents of charging inlet output end are carried out using predefined drawing load strategy on the VBUS of mobile terminal
Draw and carry, the current value of charger detection charging inlet output.Wherein, mobile terminal draws the strategy for carrying VBUS electric currents for intermittence is pressed
Drawing load is carried out to VBUS electric currents according to default pulling load current, i.e., VBUS electric currents is carried out according to default pulling load current repeatedly drawing load, and
Draw twice and be separated with preset interval time between carrying.
Further, used safely in the range of power requirements to ensure charger, for presetting setting for pulling load current
Putting needs the actual output current for ensureing charger to be less than or equal to output-current rating.The setting for presetting pulling load current is based on filling
The rated output power of electrical equipment.Specifically, the present VBUS pull-up of mobile terminal carries a low current, and detects charging IC inputs
Voltage；The electric current that VBUS pull-up is carried is improved step by step, is both needed to detect the voltage of charging IC inputs after raising electric current gear every time,
And contrasted with the default voltage thresholds of charging IC, continue to improve the electricity that VBUS pull-up is carried if less than voltage threshold
Stream, if reaching default voltage threshold, it is determined that power output has not had surplus when charger draws load current gear current value,
The input current value of VBUS can not be further continued for improving, at this moment can determine that the output-current rating higher limit institute that the charger is supported is right
The pulling load current answered.
Preferably, the present embodiment is illustrated by taking four current values as an example, obtains four current values of charging inlet output,
Specific acquisition process is as follows：Charging inlet is obtained after the first default pulling load current value is loaded onto through drawing and continues the first Preset Time
First current value of interior output；Obtain stop drawing carry and after continuing for the first interval time charging inlet output the second current value；
Charging inlet is obtained after the second default pulling load current value is loaded onto through drawing and continues the 3rd electric current exported in the second Preset Time
Value；Obtain stop drawing carry and after continuing for the second interval time charging inlet output the 4th current value.
As shown in figure 3, mobile terminal is after charging inlet temperature is detected more than predetermined threshold value, the drawing to charging inlet is carried
Strategy is：Pulled up in VBUS by charging IC and carry fixed current value (such as 50mA) and duration T 0 (such as 150ms)；Continuing
Draw the electric current 500mA that carries on VBUS and persistently after 150ms, stopping pulling load current, and duration T 1 (such as 50ms)；Stopping
After pulling load current, mobile terminal draws load VBUS current values (such as 500mA) and duration T 2 (such as 100ms) again, stops afterwards
Pulling load current.The current value of front and rear pulling load current twice is identical in the present embodiment, but it is front and rear multiple to draw load strategy also to may be configured as
The current value of pulling load current is different, but draws threshold value of the current value no more than maximum pulling load current for carrying every time.
Step 202：Whether at least three current values that detection gets meet preset relation with corresponding current threshold.
Corresponding to above-mentioned steps 201, it is necessary to detect at least three electricity for getting after at least three current values are got
Whether flow valuve meets preset relation with corresponding current threshold, and the corresponding current threshold of different current values is different here, that is, charge
Interface corresponding current threshold value in corresponding current threshold during drawing load and drawing are carried and be spaced is different, so can more intuitively judge
Draw during carrying and draw the situation of change for carrying charging inlet output voltage in interval, so as to more accurately whether judge charging inlet
Needs are protected, and reduce the False Rate of protection mechanism.Illustrated as a example by obtaining 4 current values below.
First current value, the second current value, the 3rd current value and the 4th current value that get of detection with it is corresponding
Whether current threshold meets preset relation；Specially：Whether the first current value that detection gets is higher than the first pre-set current value
And continue the first Preset Time；Wherein, the first pre-set current value is less than the first default pulling load current value；Detect second for getting
Whether current value is less than the first pre-set current value and continued for the first interval time；The 3rd current value that gets of detection whether be higher than
Second pre-set current value simultaneously continues the second Preset Time；Wherein, the second pre-set current value is less than the second default pulling load current value；Inspection
Whether the 4th current value that survey gets is less than the second pre-set current value and continued for the second interval time.
For example, the first pre-set current value is set as into the 65% of the first default pulling load current value (500mA), i.e., first presets
Current value is 0.65*500mA=325mA, timing is started after the first current value is detected higher than 325mA, and detect the first electricity
Duration of the flow valuve higher than 325mA.And further detect the second electricity got after mobile terminal stops drawing load for the first time
Whether flow valuve is less than the first pre-set current value and continued for the first interval time.Similarly, detection gets when drawing and carrying for second
Whether the 3rd current value is higher than the second pre-set current value (equal with the first pre-set current value in the embodiment, to be 325mA), and
Detect higher than starting timing after 325mA, and detect duration of the 3rd current value higher than 325mA.And further detect
Mobile terminal stops second and draws whether the 4th current value got after load is less than the second pre-set current value and continues between second
Every the time.Wherein, when whether detection stops drawing the current value got after load less than certain threshold value, it is pre- that the threshold value may be configured as first
If current value or the second pre-set current value, it is 0 that may further be provided, i.e., detect that the current value for getting is after stopping drawing load
No is 0.
Step 203：If detect at least three current values is satisfied by preset relation with corresponding current threshold, one is generated
Current-order.
If detecting the first current value, the second current value, the 3rd current value and the 4th current value and corresponding current threshold
Preset relation is satisfied by, then generates a current-order.Specifically, if the first current value is higher than the first pre-set current value and continues the
One Preset Time, the second current value are less than the first pre-set current value and continue the first interval time, the 3rd current value higher than second
Pre-set current value simultaneously continues the second Preset Time, the 4th current value less than the second pre-set current value and continued for the second interval time,
Then generate a current-order.
By taking above-mentioned example as an example, if draw for the first time carry during the first current value for getting higher than 325mA and it is lasting when
Between reach 150ms, then labeled as 1, otherwise labeled as 0.If being got during stopping drawing load after first time draws load to terminate
The second current value for 0 and the duration reach 50ms, then labeled as 0, otherwise labeled as 1.If drawing for second obtained during carrying
The 3rd current value got is higher than 325mA and duration to reach 100ms, then labeled as 1, otherwise labeled as 0.If second is drawn
The 4th current value that load stops being got during drawing load after terminating is 0 and duration to reach for the second interval time (such as
10ms), then labeled as 0, otherwise labeled as 1.So when parse above-mentioned first current value, the second current value, the 3rd current value and
After 4th current value, obtain generating current-order during the marker bit labeled as 1010, current-order is not generated otherwise.
Step 204：According to the current-order of generation, the output voltage of charging inlet is turned off.
After current-order generation has been detected, the requirement of the current-order is responded, by the defeated of the charging inlet of charger
Go out voltage shut-off, to protect the safety of the charging inlet of the mobile terminal being connected with charger.When user plugs charger again
During input, charger is re-powered can recover normal output.
It is worthy of note that, the instruction cited by the present embodiment is 1010, but is not limited according to this, using other instruction inspections
Survey mode also can, and current values cited in above-mentioned example and time numerical value is illustrative only, it is considered to practical application
When also may be set to other specification numerical value.
Because the voltage control method of the charging inlet of the embodiment of the present invention is obtained by charger and detects that charging inlet is
No exception, and it is determined that charging inlet actively cuts off power supply when abnormal, so as to avoid burning out because of formation big current loop
The problem of charging inlet or charger.It is by charging inlet, especially additionally, in the voltage control method of the charging inlet
It is that the VBUS of charging inlet realizes the current-order interaction of mobile terminal and charger and controls, therefore Micro need not be passed through
The cc passages realization of the D+/D- signalling channels or Type C of USB interface, needs not rely on the Charging of two-way communication in realization
System, goes for common standard charging system (D+/D- acquiescences are shorted together) and the fast charging system of high pressure, with higher
Versatility.
