Fig. 2 shows the block diagram for the charging system that another exemplary embodiment provides, in charging shown in above-mentioned Fig. 1
On the basis of system, as shown in Fig. 2 battery management chip 132 includes VBus and GND, and battery management chip 132 passes through VBus
It is electrical connected with GND and hardware charging inlet 131.
After hardware charging inlet 131 receives the DC voltage of the transmission of charging wire 120, i.e., by VBus to battery management core
The input direct voltage of piece 132, accordingly, battery management chip 132 receives the DC voltage by VBus.Flow through battery management core
The DC voltage of piece 132 flows out from GND (low potential), and flows to power supply adaptor 110 by charging wire 120, is formed complete
Charge circuit.
During the impedance of charging wire 120 is calculated, battery management chip 132 is to gather at least two groups of tests at VBus
Data, and the impedance of charging wire is calculated according at least two groups of test datas, wherein, comprising simultaneously in every group of test data
Actual voltage value and actual current value at the VBus of collection.
In one embodiment, when collecting two groups of test datas, battery management chip 132 is i.e. according to two groups of test data meters
Calculation obtains the impedance of charging wire 120；
In one embodiment, when collecting n group test datas, n >=3, battery management chip 132 is according to every two groups of tests
An impedance reference value is calculated in data, and the average value of n* (n-1)/2 impedance reference value is defined as into charging wire 120
Impedance.
The detailed process for calculating battery management chip 132 impedance of charging wire 120 below schematically illustrates.
As shown in Fig. 2 battery management chip 132 also includes D+ and D-, and battery management chip 132 is by D+ and D- and firmly
Part charging inlet 131 is electrical connected, and the D+ and D- are used to carry out data or signal transmission.
In order to ensure constant, the battery management core of DC voltage holding that power supply adaptor 110 exports during computing impedance
Piece 120 sends test instruction by D+ or D- when detecting with power supply adaptor foundation connection to power supply adaptor 110,
The test instructs the DC voltage that constant voltage values are exported for indicator power adapter 110.
In one embodiment, output voltage values are also included in test instruction, it is defeated with this for indicator power adapter 110
Go out the DC voltage of magnitude of voltage output, wherein, the output voltage values are less than or equal to the maximum charging voltage of mobile terminal.
Accordingly, after power supply adaptor 110 receives test instruction, by the voltage conversion chip of inside by alternating current
Pressure is converted to the DC voltage of constant voltage values, and transmits DC voltage to mobile terminal 130 by charging wire 120.
In one embodiment, while constant DC voltage is exported, power supply adaptor 110 passes through internal adapter tube
Manage chip (not shown) and send feedback command to mobile terminal 130, the feedback command is used to indicate just with constant voltage values
Export DC voltage.
Battery management chip 132 possesses charging current regulatory function, for example, battery management chip 132 can by metal-
MOSFET (Metal-Oxide-Semiconductor Field-Effect Transisto,
MOSFET charging current) is adjusted.When receiving the feedback command of the transmission of power supply adaptor 110, battery management chip 132 is controlled
System charges by battery 133 of the first charging current, and in charging process, the collection of battery management chip 132 includes at VBus the
One actual voltage value V1 and the first actual current value I1 the first test data.
After collecting the first test data, battery management chip 132 is adjusted to charging current, is controlled with the second charging
Electric current is that battery 133 charges, and collection includes the second actual voltage value V2 and the second actual current at VBus in charging process
Value I2 the second test data.
It should be noted that the first charging current is different with the second charging current, and the first charging current and the second charging
Electric current is respectively less than the specified charging current of battery 133, and the specified charging current refers to the maximum charging current for battery charging, example
Such as, when specified charging current is 1.5A, the first charging current is 0.5A, and the second charging current is 0.8A.
Because power supply adaptor 110 exports constant DC voltage, therefore successively twice in measurement process, charging wire 110
The voltage shared keeps constant, i.e. R × I with flowing into the virtual voltage sum of battery management chip 1321+V1=R × I2+V2, its
In, R is the impedance of charging wire 120.R=(V can obtain according to above-mentioned equation1-V2)/(I2-I1)。
Obviously, battery management chip 132 can not know power supply adaptor 110 export accurate voltage values in the case of,
It is still able to be calculated the impedance of charging wire 120 according to the first test data for collecting and the second test data, and due to
V in above-mentioned formula1、V2、I1And I2It is actual measured value, therefore, the accuracy for the impedance being calculated is higher.
After the impedance of charging wire 120 is calculated, battery management chip 132 further determines charging current according to the impedance
Coefficient is lowered, and coefficient and specified charging current reset charging current are lowered according to the charging current, so as to according to setting
Charging current afterwards is that battery 133 charges.Wherein, impedance is previously stored with battery management chip 132 to lower with charging current
Corresponding relation between coefficient, schematically, the corresponding relation are as shown in table 1.
Table 1
| Charge line impedence R | Charging current lowers coefficient |
| The Ω of R ＜ 0.3 | 1 |
| 0.3 Ω≤the Ω of R ＜ 0.5 | 0.7 |
| 0.5 Ω≤the Ω of R ＜ 1.0 | 0.5 |
| 1.0 Ω≤the Ω of R ＜ 3.0 | 0.3 |
| R≥3.0Ω | 0 |
For example, when the impedance that charging wire is calculated is 0.2 Ω, battery management chip 132 using specified charging current as
Battery 133 charges；In another example the impedance that charging wire is calculated in battery management chip 132 is 0.45 Ω, and specified charging current
For 1.5A, then charging current is set as 1.5 × 0.45=0.675A；In another example when the impedance that charging wire is calculated is 3.5
During Ω, battery management chip 132 stops charging to battery 133.
In the present embodiment, battery management chip exports constant DC voltage by D+ or D- indicator power adapters, and leads to
The mode for crossing adjustment charging current gathers at least two groups of test datas VBus at, so that according to the reality included in the test data
The impedance of charging wire is calculated in border magnitude of voltage and actual current value, it is ensured that it is reality to calculate the data used during charging line impedence
Border measured value, improve the accuracy for the charging line impedence being calculated.
