Embodiment
Technical solution of the present invention is described in detail below by accompanying drawing and specific embodiment, it will be appreciated that this hair
Particular technique feature in bright embodiment and embodiment is the explanation to technical solution of the present invention, rather than is limited, not
In the case of conflict, the particular technique feature in the embodiment of the present invention and embodiment can be mutually combined.
As shown in Figure 1 be the embodiment of the present invention in a kind of flow chart of multi output interface fast charge control method, first for,
This method is applied in fast charging device, and the fast charging device is as shown in Fig. 2 the fast charging device includes multiple output interfaces and voltage
Converter, the output voltage of each output interface are provided by voltage changer, and this method includes：
S101, detect each output interface and inserted with the presence or absence of the first access device；
As shown in Fig. 2 this method can specifically be performed by controller, the controller is not only connected with each output interface,
And it is connected with voltage changer.
, it is necessary to be initialized to the device before device is started working, if voltage changer is closed,
Without output voltage, all output interfaces are closed；Certainly when voltage changer is in running order, voltage changer will export one
Default voltage, in general the default voltage be arranged to 5v.
Certainly, device is in running order is, by the real-time detection for carrying out access device, that is, each output of detection
Interface inserts with the presence or absence of access device.
If in the absence of equipment access insertion, then controller, voltage changer are all by the working condition in acquiescence.Here
It should be noted that then the detection of access device can be completed by controller, or completed, and passed by each output interface
Defeated testing result is to controller.
Certainly, if accessed in the presence of the first access device, then step S102 is performed.
S102, if the first output interface has the insertion of the first access device, the first output interface is opened, and open fast charge
Function；
When the insertion of the first access device on the first output interface be present, it is possible to examined by output interface or controller
Measure the insertion of the first access device.
When the first access device inserts, controller will control the first output interface to open, and open fast charge function.
S103, judges whether the first access device supports fast charge；
Herein, controller will detect whether to receive the fast charge request of the first access device, if receiving the first access
During the fast charge request of equipment, it is determined that first access device supports fast charge function, step S104 will be now performed, if not examining
When measuring the fast charge request of the first access device, then illustrate that the first access device does not support fast charge function, will now perform S105.
S104, control voltage converter adjust output voltage to the fast charge voltage of the first access device；
That is, on the premise of the first access device supports fast charge, controller will determine the fast of the first access device
Charging voltage, then voltage is adjusted to the fast charge voltage by control voltage converter by controller, so that the first output interface exports
Voltage be just the fast charge voltage.
S105, maintain the default voltage of the first output interface.
When the first access device does not support fast charge, controller is by the default voltage of maintenance voltage converter.So as to ensure
For the charging of the first access device.
Can substantially it be obtained by above-mentioned method, when being that access device charges separately through an output interface, often
Individual output interface can provide fast charge function, without providing corresponding function using multiple voltage changers, reduce
Number of elements and design cost.
Further, in embodiments of the present invention, the first output interface, and the first output are inserted into the first access device
Interface is that controller will also continue to detect in remaining output interface to be set with the presence or absence of other accesses after the first access device charges
Standby insertion.
If until the first access device is pulled out from the first output interface, or the first access device charging complete it
Afterwards, still without other access devices access, then pulled out in the first access device, or the first access device charging complete it
Afterwards, controller will close the first output interface.Then proceed to detect output interface.
If during the first access device charges, detect that the second output interface inserts the second access device, then
Further judge currently whether open fast charge function.
If currently opening fast charge function, then controller can be handled by two ways：
First way be controller directly close fast charge agreement, after the preset lime either voltage changer it is defeated
Go out voltage to return to after default voltage, controller will open the second output interface, so that the second output interface output electricity
Pressure disclosure satisfy that the charge requirement of the second access device.
The second way is that controller judges currently whether be in fast charge pattern, if fast charge pattern is in, and
Fast charge export, then be first shut off the first output interface having been switched on, simultaneously close off all fast charge functions, preset time it
After reopen the first output interface, and open the second output interface.
Further, if the 3rd access device, the insertion of the 4th access device subsequently be present, then controller directly opens the
Three output interfaces and the 4th output interface, and the 3rd output interface and the 4th output interface are the 3rd by default voltage
Access device, the 4th access device are charged, and can so be charged simultaneously for multiple access devices, be reduced the total work of device
Rate, and reduce caloric value.
Further, in embodiments of the present invention, when device is that multiple access devices charge simultaneously, controller will be lasting
All access devices for inserting output interface are detected with the presence or absence of pulling out or having been filled with, some access device be present
Pull out or have been filled with, then close output interface corresponding to the access device, such as, mistake of second access device in charging
Pulled out in journey, then controller will close the second output interface；If the charging complete of the second access device, controller will also close
The second output interface is closed, can so avoid the waste of electric power.
Further, in embodiments of the present invention, pulled out if access device is lasting, control and connect lasting closing output
Mouthful, now controller will detect and currently be in opening with the presence or absence of unique output interface, if one output of existence anduniquess
Interface is in opening, that is, when being charged in the presence of an access device, the controller is by current access device is detected
No support fast charge function, if the access device supports fast charge function, then controller opens fast charge function, and then controller will be controlled
Voltage is adjusted to the fast charge voltage by voltage changer processed, so as to which the voltage of the first output interface output is just the fast charge voltage.
Certainly, if access device does not support fast charge function, then controller exports maintenance voltage converter with default voltage, by this
Method can support the situation of fast charge function in the state of it last output interface be present and open, and in access device
Under, device will recover fast charge function automatically, so that the charge efficiency of access device is higher.
It is further to note that fast charge agreement signified in the embodiment of the present invention including but not limited to QC2.0, QC3.0,
The fast charge agreement such as MTK PE1.1, MTK PE2.0, AFC, FCP, SCP, SFCP, VOOC, PD2.0, PD3.0.
Further, a kind of multi output interface fast charge control device is additionally provided in embodiments of the present invention, is illustrated in figure 3
A kind of structural representation of multi output interface fast charge control device, the device include in the embodiment of the present invention：Output interface 301,
Controller 302, voltage changer 303.
