When compare for first estimation parameter be less than first predetermined value when, reduce the pre-output parameter of charging equipment, and determine
Pre-output parameter after reduction is the target output parameter of charging equipment.
In such scheme, it is contemplated that：The resistance of the charging wire read can be an occurrence, or a model
Enclose value.The resistance of charging wire is that a value range is the demand for being on the one hand to carry out collocation from different charging equipments and use；
On the other hand, the Vin of electronic equipment is changeless to reach the high efficiency of charging within a period of time, it is also necessary to according to
Vin change calculates the change of resistance, i.e., selects a rational resistance value from resistance range value by the calculating, and according to
Reasonable adjusting is carried out according to output of this resistance value to charging equipment, on the one hand can meet the high efficiency of charging, on the other hand may be used
Meet to reduce the demand being lost caused by the presence of resistance on charging wire as far as possible；And charging wire can fill with different size
Electric equipment carries out arrange in pairs or groups use and phenomena such as the overheating, damaging that will not cause to charge, and can meet the intellectuality of charging, become more meticulous pipe
Reason.
Aforementioned schemes are described further with reference to Fig. 6.
In figure 6, in this side of electronic equipment, on the basis of battery circuit, control circuit is increased.Wherein, control electricity
Road includes resistance R1, R2 and switch 1；Battery circuit includes resistance R3, switch 2 and battery.
In charging process, the Vin of electronic equipment is changeless within a period of time, when it changes
The high efficiency wanting to reach charging every one section of impedance to charging wire, it is necessary to calculate, and according to this resistance value to charging
The output of equipment carries out reasonable adjusting, to ensure smoothly completing for charging process.
In charging process, the switch 2 in battery circuit is got on position 3, and the switch 1 of control circuit is got on position 2,
Only it is that charging input current Vin is directly inputted to battery by R3, with right namely control circuit is off-state in charging process
Battery is charged.
When knowing Vin when electronic equipment and changing and (become V ' in), the switch 2 of battery circuit gets to position 4 from position 3
On, the switch 1 of control circuit is got on position 1 from position 2, i.e., now battery circuit is off-state without charging.At this
In the case of kind, the resistance of resistance R1 and R2 in electronic equipment read control circuit, and pass through USB-PD agreements (USB Power
Delivery Specification, USB charge protocol) know the charging output parameter Vbus of charging equipment, so
Calculated afterwards according to formula (1), obtain the estimation impedance Rx of charging wire：
Wherein, resistance R1 and R2 impedance value is one group of impedance parameter, is the property parameters of electronic equipment；Vbus is electronics
The input voltage parameter of equipment, it is the property parameters of electronic equipment.
Foregoing is that electronic equipment is that impedance Rx is estimated as obtained from knowing a Vbus.In view of the resistance to charging wire
The accuracy of anti-estimation, at least two Vbus can be known, one is calculated according to formula (1) for each Vbus known
The impedance of individual charging wire, and the impedance value of all charging wires calculated is subjected to average value and asked for, so as to draw final fill
The estimation impedance value (the first estimation parameter) of electric wire.Next, electronic equipment estimates parameter and predetermined desired impedance by first
Value (first predetermined value) is compared；
When compare for first estimation parameter be more than or equal to first predetermined value when, illustrate now charging wire actual resistance compare manage
Think that impedance value is big, the energy so expended on charging wire increases, for being normally carried out, it is necessary to increase charging for guarantee charging process
Vbus/Ibus after increase is sent to charging and set by the output parameter of equipment such as Vbus/Ibus, electronic equipment by charging wire
It is standby, to cause charging equipment to be charged using the Vbus/Ibus after increase to electronic equipment.Wherein, charging equipment utilizes increasing
Vbus/Ibus after big charges to electronic equipment, the energy consideration expended on charging wire is entered, after increase
Vbus/Ibus charges to electronic equipment, even if the output energy of charging equipment nor affects on charging wire in the presence of consuming
Charging to electronic equipment；Namely fallen the voltage/current synthesis expended on charging wire using the Vbus/Ibus after increase,
The output voltage/electric current (Vbus/Ibus) of charging equipment can still protect when expending by charging wire and reaching electronic equipment side
Hold input voltage/electric current (Vin/Iin) expected from electronic equipment.
When compare be less than first predetermined value for the first estimation parameter when, illustrate the actual resistance of now charging wire than ideal resistance
Anti- value is small, and the energy so expended on charging wire is smaller, and the output parameter of charging equipment now can be carried out to appropriate subtract
It is small, it can ensure to charge normal.That is electronic equipment reduces the pre-output parameter of charging equipment, and determines pre- defeated after reducing
Go out parameter and be the target output parameter of charging equipment, and the Vbus/Ibus after reduction is sent to charging equipment by charging wire,
To cause charging equipment to be charged using the Vbus/Ibus after reduction to electronic equipment.In this way, do not wasting the basis of energy
On realize efficient charging.
Wherein, the increase of pre-output parameter, the amplitude reduced can take any reasonable value, be not specifically limited.
After electronic equipment regulates the target output parameter of charging equipment for V ' in, electronic equipment control battery electricity
Switch 2 in road is got on position 3, and the switch 1 of control circuit is got on position 2, namely starts to perform charging in charging process
Process.Charging equipment is charged using the output parameter after regulation to electronic equipment.
In such scheme, according to the property parameters (R1, R2 and input voltage parameter) of electronic equipment, to the electricity of connecting line
Gas parameter (impedance value) is estimated, obtains the first estimation parameter (decision value)；Based on the first estimation parameter, charged
The target output parameter of equipment；Target output parameter is sent to charging equipment by connecting line, so that charging equipment passes through output
The target output parameter charges to electronic equipment.By the accurate estimation of the impedance value to connecting line, charging would know that
Line currently with charging equipment, electronic equipment condition of contact under the accurate impedance value that accesses；Can be to charging according to the impedance value
The target output parameter of equipment is accurately adjusted, efficiently to be charged to electronic equipment.Embody charging intellectuality,
Become more meticulous.
