When power supply unit is connected with first power receiving equipment, and determined first power receiving equipment power supply grade it
Afterwards, when and the function of supplying power of the power supply unit has turned on, the current powering mode that can control the power supply unit is first
Powering mode.
What needs to be explained here is that power supply unit is to have certain requirement, example for the starting current of power receiving equipment
Such as part power receiving equipment, starting current, that is, operating current is bigger, after it connect with power supply unit, if power supply unit
If opening function of supplying power, while power receiving equipment just will start, i.e., power receiving equipment initially enters power supply state, the power supply unit
It will be powered with the first powering mode for it.In this case power receiving equipment is considered standard power receiving equipment, described
First powering mode is standard powering mode.But for another part power receiving equipment, starting current works electric
Flow it is smaller, after it connect with power supply unit, if power supply unit open function of supplying power if, power receiving equipment not will start, i.e.,
Power receiving equipment does not enter power supply state also.For in this case, since power receiving equipment is in non-power supply state, it is possible to
Further judged whether it is non-standard power receiving equipment.
When the current powering mode opened function of supplying power, and control the power supply unit is inspection after the first powering mode
Survey the current power supply state of first power receiving equipment.It, can be with when detecting that first power receiving equipment is in power supply state
It determines that first power receiving equipment is standard power receiving equipment, is standard device power supply by first powering mode.
When detecting that first power receiving equipment is in non-power supply state, judge whether first power receiving equipment is non-
Standard power receiving equipment.Here judge whether first power receiving equipment is that the mode of non-standard power receiving equipment can be and pass through acquisition
The port current of first power receiving equipment, judges whether the port current meets the first preset condition, if satisfied, then can be with
Determine the first power receiving equipment criteria of right and wrong power receiving equipment.
Whether the above-mentioned port current for judging first power receiving equipment, which meets preset condition, can be and judge described first
Whether the port current of power receiving equipment is less than preset value, and the preset value can be 10ma, is also possible to other values.When judging
The port current of first power receiving equipment is less than after preset value, it may be determined that first power receiving equipment is set to be non-standard by electricity
It is standby.
It arrives here, step 101 is finished, i.e., determining power supply unit is connect with the first power receiving equipment and the power supply unit
Function of supplying power have turned on, but the current power supply state of the first power receiving equipment be in non-power supply state and determine described first
Power receiving equipment is non-standard power receiving equipment.Then start execute step 102, i.e., by the current powering mode of the power supply unit by
First powering mode is switched to second powering mode different from first powering mode；So that the power supply unit is with described
Second powering mode is first power receiving equipment power supply；
Optionally, first powering mode is when the power supply unit and first power receiving equipment are in and connect in step 102
When connecing state, the detection chip of the starting current in the power supply unit for detecting first power receiving equipment is defaulted as enabling

It is the second powering mode, i.e., the detection chip of the described power supply unit can not detect the starting electricity of the non-standard power receiving equipment
It flows into and can not judge whether the non-standard power receiving equipment is pulled out.If user extracts the non-standard power receiving equipment
, the power supply unit still can be continuously the power supply of the port where the non-standard power receiving equipment, such as described non-standard
The power supply grade of power supply unit is 1 grade, then the power supply unit can continue to export the power of 15W.In this case, if with
When another power receiving equipment is accessed the port again by family, if if another power receiving equipment can not support the power of 15W, that
Another power receiving equipment will be damaged.
Optionally, the second preset condition mentioned herein can be identical with above-mentioned first preset condition, can also be different.Example
Such as, the port current of first power receiving equipment is periodically obtained, the period here, which can be, obtains one every 1s or 2s
Secondary port current, the specific time cycle present invention do not limit specifically.Judge whether the port current obtained every time meets
Second preset condition, for example whether being less than preset value.Here preset value can be 10ma and be also possible to other values.When no less than
When the port current obtained twice all meets the second preset condition, first power receiving equipment and the power supply unit are determined
It is in an off state, at this moment the current powering mode can be switched to the first power supply mould from second powering mode
Formula.
