Next, a software environment applied to the charging protection method provided by the embodiment of the present invention is described by taking an android operating system as an example.

In fig. 2, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the charging protection method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 2, so that the charging protection method may operate based on the android operating system shown in fig. 2. Namely, the processor or the terminal device can implement the charging protection method provided by the embodiment of the invention by running the software program in the android operating system.
The charging protection method according to the embodiment of the present invention is described below with reference to a flowchart of the charging protection method shown in fig. 3, where fig. 3 is a schematic flowchart of a charging method according to the embodiment of the present invention, and the charging protection method includes steps 201 and 202:
step 201: the terminal device detects the connection state of the charger in the process that the charger charges the battery of the terminal device.
In the embodiment of the present invention, there are two connection states of the charger, one state is used to indicate that the terminal device is not connected, that is, the charger is not connected to the charging interface of the terminal device, and the other state is used to indicate that the terminal device is connected, that is, the charger is connected to the charging interface of the terminal device.
Step 202: and when the terminal equipment detects that the connection state indicates that the terminal equipment is not connected, the charging switch tube of the terminal equipment is controlled to be cut off.
The charging switch tube is used to turn on and off a path between a charging interface of the terminal device and a battery of the terminal device, and may refer to the switch Q1 and the switch Q2 in fig. 1.
In the embodiment of the invention, as in a normal situation, a processor inside the terminal device generally controls a driving circuit inside the terminal device to send a high-voltage control signal to the charging switch tube so as to control the on and off of the charging switch tube, when the terminal device detects that the connection state indicates non-connection, an alarm can be sent to the processor, and the processor sends a control signal to the charging switch tube based on the alarm driving circuit so as to control the off of the charging switch tube.
Optionally, in the embodiment of the present invention, the terminal device may detect the connection state of the charger in two ways.
According to the charging protection method provided by the embodiment of the invention, in the process of detecting that the charger charges the battery of the terminal equipment, the connection state of the charger is detected, so that when the connection state indication is not connected, the charging switch tube of the terminal equipment is immediately controlled to be cut off, and the path between the charging interface of the terminal equipment and the battery is cut off, thereby avoiding the electric leakage of the charging interface.
In one possible implementation:
exemplarily, referring to fig. 3, as shown in fig. 4, the step 201 includes the following steps:
step 201a 1: the terminal device detects the charging voltage of the charging interface, the voltage of the battery and the discharging current of the battery in the process that the charger charges the battery of the terminal device.
Step 201a 2: if the charging voltage is less than or equal to the voltage of the battery and the discharging current is greater than 0 in the preset time period, the terminal equipment determines that the connection state indication of the charger is not connected, and otherwise, determines that the connection state indication is connected.
Wherein, the current of the battery comprises the charging current of the battery and the power consumption current of the terminal equipment.
Illustratively, the battery is usually provided with a fuel gauge circuit, and therefore, the terminal device can read the voltage Vbat of the battery and the charge/discharge current Ibat of the battery, etc. in real time through the fuel gauge circuit. In addition, the voltage Vbat of the battery may also be read in real time by a processor of the terminal device (for example, an MCU or a CPU in the terminal device), and the processor of the terminal device may also read the charging voltage Vbus of the charging interface in real time.
For example, taking the charging architecture shown in fig. 1 as an example, it is assumed that the charging battery of the battery is I1, the power consumption current of the terminal device is I2, the resistance of the charging switch tube when it is turned on is R, the voltage of the battery is Vbat, and the charging voltage Vbus of the charging interface. Then Vbus-Vbat + (I1+ I2) × R, i.e. Vbus-Vbat ═ (I1+ I2) × R, so that, during the process of charging the terminal device by the charger, if the charger is pulled out, the charging battery I1 charged into the battery becomes 0A instantaneously, the current flowing out from the battery is I2, and Vbus-Vbat ═ R (I2) × R, at which time, (I2) × R ≦ 0. Therefore, Vbus-Vbat is less than or equal to 0 and the current flowing out of the battery, the connection state of the charger is determined to indicate not connection, and the connection state of the charger is determined to indicate connection when Vbus-Vbat is greater than 0.
In combination with the above, the terminal device can determine the connection state of the charger by determining whether the difference between the charging voltage and the voltage of the battery is less than zero.
In the embodiment of the present invention, the terminal device may perform multiple detections on the charging voltage of the charging interface and the voltage and the discharging current of the battery within a predetermined time (e.g., 200ms), and determine that the connection status of the charger indicates no connection only when the charging voltage is less than or equal to the voltage of the battery and the discharging current is greater than 0.
In the embodiment of the invention, in the process of detecting that the charger charges the battery of the terminal device, the charging voltage of the charging interface, the voltage of the battery and the discharging current are detected, so that whether the charger is in the pull-out state is judged by detecting the charging voltage of the charging interface, the voltage of the battery and the discharging current of the battery, when the charger is detected to be in the pull-out state, the charging switch tube of the terminal device is immediately controlled to be cut off, and the path between the charging interface of the terminal device and the battery is cut off, so that the electric leakage of the charging interface can be avoided.
In two possible implementations:
exemplarily, referring to fig. 3, as shown in fig. 5, the step 201 includes the following steps:
step 201b 1: and the terminal equipment sends a detection signal to the charger.
In the embodiment of the invention, the terminal equipment sends a detection signal to the charger, if the charger feeds back a response signal to the terminal equipment, the detection signal is continuously sent, and if the charger does not feed back the response signal to the terminal equipment, the charger is judged to be pulled out, namely, the connection state indication of the charger is determined to be unconnected.
Further, in the embodiment of the present invention, the terminal device sends the detection signal to the charger according to a predetermined period, wherein at least one detection signal is sent in one period. For example, when the terminal device periodically transmits the detection signal, one detection signal may be transmitted in one period, or a plurality of detection signals may be transmitted in one period.
The predetermined period may be flexibly set by the user according to the actual application scenario, or may be a fixed value, which is not limited in the present invention.
In one example, the terminal device sends a detection signal and receives a response signal fed back by the charger through a D +/D-data line of a microUSB or TypeC interface port. Illustratively, taking the D +/D-data line of the TypeC interface port as an example, the terminal device may send a CLK signal over the D + data line and a detection signal (8 bits per command) over the D-data line, e.g., the detection signal is transmitted during CLK high level. Generally, D +/D-always has a detection signal when in quick charging, and the sending period is 20 ms.
Step 201b 2: and if the terminal equipment does not receive the response signal fed back by the charger, determining that the connection state indication of the charger is not connected, otherwise, determining that the connection state indication is connected.
In the embodiment of the present invention, if the terminal device does not receive the response signal fed back by the charger, it indicates that the connection between the charger and the terminal device is abnormal, so that the terminal device cannot receive the response signal fed back by the charger, or the charger does not receive the detection signal. Otherwise, the terminal equipment receives the response signal fed back by the charger, and the charger is normally connected with the terminal equipment.
Further, the step 201b2 specifically includes the following steps:
step A: and if the terminal equipment does not receive a response signal fed back by the charger after continuously sending M detection signals, determining that the connection state indication of the charger is not connected, wherein M is an integer greater than 1.
For example, in order to improve the detection accuracy, the terminal device may determine that the charger has been unplugged and determine that the connection state of the charger indicates no connection in a case where the charger continuously transmits M detection signals to the terminal device without a response signal.
In one example, M detection signals correspond to one response signal, that is, the terminal device determines that the charger has been pulled out when the terminal device does not receive the corresponding response signal after continuously transmitting the M detection signals.
In another example, one detection signal corresponds to one response signal, that is, it is determined that the charger has been pulled out as long as the number of consecutive times that the charger does not respond reaches M times.
In the embodiment of the invention, the terminal equipment sends the detection signal to the charger in the process that the charger charges the battery of the terminal equipment, so that whether the charger is in the pull-out state is judged by judging whether the charger feeds back the response signal to the terminal equipment, when the charger is detected to be in the pull-out state, the charging switch tube of the terminal equipment is immediately controlled to be cut off, and the path between the charging interface of the terminal equipment and the battery is cut off, so that the electric leakage of the charging interface can be avoided.
