For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The charging method according to the embodiment of the present invention is executed by a computer program and can be executed on a computer system of von-rhodamine system. The computer program may be run on the basis of a charging device. The charging device can be a mobile terminal device such as a personal computer, a tablet computer, a notebook computer, a smart phone and an intelligent wearable device.

The following are detailed below.

Fig. 1 is a schematic flow chart of a charging method according to an embodiment of the present invention, as shown in the figure, the method at least includes:

step S101, acquiring a port type of a charger, and judging whether the port type is a special charging port DCP type.

Specifically, a Charging device, such as a mobile phone, a tablet computer, or a personal computer, is connected to a charger through a Universal Serial Bus (USB) Port of the charger, and after the Charging device is connected to the charger, detects a Port type of the charger under a USB Charging specification (USB Charging 1.2, BC1.2), and determines whether the detected Port type is a Standard Downlink Port (SDP) type or a Charging Downlink Port (CDP) type. Among other things, the BC1.2 specification determines how each port should be enumerated to the end device, as well as the protocol that identifies the port type.

In addition, the Port types of the USB BC1.2 specification are shown in table 1, and include SDP, CDP, Charging downstream Port (DCP), and other Port types.

Judging whether the port type is a special charging port DCP type, including:

acquiring a first voltage of a positive electrode signal D + of a differential line and a second voltage of a negative electrode signal D-of the differential line;

when the first voltage is greater than a first voltage threshold and the second voltage is greater than a second voltage threshold, connecting a pull-up power supply of the D-and a pull-down power supply of the D + to obtain the level of the D +;

and if the level of the D + is high level, determining that the port type is a DCP type.

TABLE 1

In the concrete implementation, when the charging device is connected to a DCP type charger, firstly, because the (Data +, D +) signal level of the charging equipment is higher than the D + signal comparison level of the charger, and the D + and (Data-, D-) signals of the DCP type charging are short-circuited, the D-signal is pulled high and is higher than the judgment level of the D-signal, and the port type of the charger is identified as the DCP type or the CDP type; and then turning on a pull-up power supply of the D-signal of the charging device, namely maintaining the D-signal to be high level, turning off the pull-up power supply of the D + signal, and simultaneously turning on a pull-down power supply of the D + signal, wherein the D + signal becomes high level, namely when the D + signal of the charging device is detected to be high level, determining that the port of the charger is of a DCP type.

Among them, the Dedicated Charging Port (DCP) type port does not support any data transmission but can supply a current of 1.5A or more, and thus is commonly used for a wall charger and an in-vehicle charger supporting a higher charging capability without enumeration.

In this embodiment, the charging device obtains a D + voltage and a D-voltage in the charging device after the charging device is connected to the charger, and respectively compares the D + voltage and the D-voltage with corresponding preset thresholds, and when the comparison result is that both of the D + voltage and the D + voltage are greater than the corresponding preset thresholds, obtains a level of D + under the condition of a pull-up power supply connected to D + and a pull-down power supply connected to D +, and determines that the port type is the DCP type when the level of D + is a high level.

Optionally, after determining whether the port type is a DCP type, the method further includes:

when the port type is not the DCP type, judging whether the port type is a standard downlink port SDP type or a charging downlink port CDP type;

when the port type is the SDP type, charging by adopting a first preset current threshold;

when the port type is the CDP type, charging by adopting a second preset current threshold value;

and when the port type is not the SDP type and not the CDP type, charging by adopting a third preset current threshold value.

Specifically, when the port type is the SDP type, a first preset current threshold is used for charging. For the SDP type port charger, the corresponding current limiting values are 2.5mA when suspended, 100mA when connected, and 500mA when connected and configured as a higher power, respectively, and the first preset current threshold may be 500 mA; when the port type is the CDP type, charging by adopting a second preset current threshold, wherein the second preset current threshold can be 900 mA; and when the port type is not the SDP type and not the CDP type, charging by adopting a third preset current threshold, wherein the second preset current threshold can be 500 mA.

Judging whether the port type is a standard downlink port SDP type or not, wherein the judging comprises the following steps:

acquiring a third voltage of a positive electrode signal D + of a differential line and a fourth voltage of a negative electrode signal D-of the differential line, wherein the third voltage and the fourth voltage are voltages before being connected with the charger;

acquiring a fifth voltage of a positive electrode signal D + of a differential line and a sixth voltage of a negative electrode signal D-of the differential line, wherein the fifth voltage and the sixth voltage are voltages after being connected with the charger;

determining that the port type is the SDP type when the third voltage is greater than the fifth voltage and the fourth voltage is greater than the sixth voltage.

In a specific implementation, since the terminals of the SDP are provided with 15k Ω pull-down resistors on the positive signal line D + and the negative signal line D-lines of the terminals of the SDP, when the charging device is connected to the SDP type charger, the D + voltage of the charging device is pulled down by the pull-down resistor of the internal D + signal of the charger, and the D-voltage of the charging device is also pulled down by the pull-down resistor of the internal D-signal of the charger, i.e., when the charging device (access device) detects that the D + voltage and the D-voltage inside the charging device are both low after the charger is connected, the terminals of the charger are determined to be of the SDP type.

In this embodiment, the D + and D-voltages of the charging device before the connection with the charger and the D + and D-voltages of the charging device after the connection with the charger are respectively obtained, and then the D + voltage before and after the connection are respectively compared with the D-voltage to determine whether both the D + voltage and the D-voltage before the connection become small.

Judging whether the port type is a charging downlink port CDP type or not, wherein the judging comprises the following steps:

acquiring a seventh voltage of a positive electrode signal D + of a differential line and an eighth voltage of a negative electrode signal D-of the differential line;

when the seventh voltage is greater than a third voltage threshold and the eighth voltage is greater than a fourth voltage threshold, connecting the pull-up power supply of the D-and the pull-down power supply of the D + to obtain the level of the D +;

and if the level of the D + is low level, determining that the port type is the CDP type.

In specific implementation, when the charging device is connected to a CDP type charger, firstly, because the D + signal level of the charging equipment is higher than the D + signal comparison level of the charger, the CDP equipment is powered on, the D-signal is pulled high and is higher than the judgment level of the D-signal, and the port type of the charger is identified as the CDP type or the DCP type; and then, turning on a pull-up power supply of the D-signal of the charging device, namely maintaining the D-signal to be high level, turning off the pull-up power supply of the D + signal, and simultaneously turning on a pull-down power supply of the D + signal, wherein the D + signal is changed into low level, namely when the D + signal of the charging device is detected to be low level, determining that the port of the charger is of the CDP type.

The Charging Downstream Port (CDP) type port not only supports large-current charging, but also supports data transmission fully compatible with USB 2.0, and the port is provided with a 15k omega pull-down resistor necessary for D + and D-communication, and also is provided with an internal circuit for switching in a charger detection stage.

In this embodiment, the charging device obtains a D + voltage and a D-voltage in the charging device after the charging device is connected to the charger, and respectively compares the D + voltage and the D-voltage with corresponding preset threshold values, and when the comparison result is that both are greater than the corresponding preset threshold values, obtains a level of D + under the conditions of a pull-up power supply connected to D + and a pull-down power supply connected to D +, and determines that the port type is the CDP type when the level of D + is a low level.

Step S102, when the port type is the DCP type, a charging protocol is obtained.

Specifically, as shown in table 1, when the port type is the DCP type, multiple charging protocols are supported, and the charging protocols at this time are obtained, such as a concurrent rapid charging protocol (Pump Express Plus 3.0, PE +3.0), a concurrent rapid charging protocol (Pump Express Plus 2.0, PE +2.0), and a high-pass rapid charging protocol (Quick Charge 2.0, QC 2.0).

And step S103, when the charging protocol comprises a high-pass quick-charging protocol QC2.0, charging by adopting a charging scheme corresponding to the QC 2.0.

Specifically, the high-pass quick-charging protocol QC2.0 is a quick-charging protocol, and the type of the charger can be automatically identified through a chip of a protocol controller, such as FP6600, and the output voltage of the charger is adjusted to obtain the highest safe charging voltage allowed by the charger, so that the charging time is saved on the premise of protecting the charger.

The charging scheme corresponding to QC2.0 is: the charger and the charging device for QC2.0 quick charging communicate by loading voltage on the signal lines D + and D-of the USB interface, and the output voltage of QC2.0 is adjusted. Specifically, when the terminal of the charger (QC2.0 identification chip FP6600) is connected to the charging device through a data line, the charger defaults to short-circuit D + and D-, and the charging device detects that the charger type is a DCP type. At this time, the output voltage was 5v, and the charging device was normally charged. If the charging device supports a QC2.0 fast charging protocol, the hvdcp process of the Android user space is started, and a voltage of 0.325V is loaded on the D +. When the voltage is maintained for 1.25s, the charger will disconnect the short circuit of D + and D-, and the voltage on D-will drop; after the charging device detects the voltage drop on D-, the value of hvdcp read/sys/class/power _ supply/usb/voltage _ max, if 9000000(mV), sets the voltage on D + to 3.3V, the voltage on D-to 0.6V, and the charger outputs 9V voltage. If D + is set to 0.6V and D-is set to 0V for 5000000(mV), the charger outputs 5V.

And step S104, when the charging protocol comprises a simultaneous rapid charging protocol PE +3.0, charging by adopting a charging scheme corresponding to the PE +3.0 or a charging scheme corresponding to the PE + 2.0.

Specifically, the charger in the charging scheme corresponding to the concurrent rapid charging protocol PE +3.0 supports a charging voltage and a charging current of 5V/7V/9V 2A or 12V1.5A, and is adaptive and adjustable.

In addition, since the protocols are all downward compatible, that is, when PE +3.0 is supported, PE +2.0 is also supported, when the charging protocol includes PE +3.0, charging can be performed by using a charging scheme corresponding to one of PE +3.0 and PE + 2.0.

And step S105, when the charging protocol comprises a simultaneous rapid charging protocol PE +2.0, charging by adopting a charging scheme corresponding to the PE + 2.0.

Specifically, PE +2.0 is a fast charging protocol of the company, and the output voltage values of the charger in the charging scheme corresponding to PE +2.0 are 3.6V, 3.8V, 4.0V, 4.2V, 4.4V, 4.6V, 4.8V, 5.0V, 7V, 9V, and 12V, and are adaptively adjustable, so as to ensure that the voltage floats during charging, and the charging device is not prone to generate heat.

Optionally, the method further includes:

when the charging protocol comprises a high-pass quick-charging protocol QC2.0, a simultaneous quick-charging protocol PE +3.0 and a simultaneous quick-charging protocol PE +2.0, respectively acquiring a priority level attribute of the QC2.0, a priority level attribute of the PE +3.0 and a priority level attribute of the PE + 2.0;

charging by adopting a charging protocol with better priority level attributes in the QC2.0, the PE +3.0 and the PE + 2.0;

wherein the priority attribute comprises at least one of a priority, a detection duration, or a detection order.

Specifically, the priority is a parameter that determines the priority level of each operating program for receiving system resources when the computer time-sharing operating system processes a plurality of operating programs, and if the priority level of the parameter is higher, the charging is performed according to a charging scheme corresponding to a protocol with higher priority level parameters in QC2.0, PE +3.0 and PE + 2.0; if the detection time is short and the priority level is high, charging is carried out according to a charging scheme corresponding to a protocol with short detection time in QC2.0, PE +3.0 and PE + 2.0; and if the priority level of the detection sequence is high, charging according to a charging scheme corresponding to the protocol detected in QC2.0, PE +3.0 and PE + 2.0.
