Bright, Fig. 3 is a kind of charging method flow diagram provided in an embodiment of the present invention, including step 201 and step 202:
Step 201: terminal device detects the connection of charger during the battery charging that charger is terminal device
State.
In embodiments of the present invention there are two types of the connection status of charger, a kind of state is used to indicate not connected, that is, charges
Device is not connected with the charging interface of terminal device, and another state is used to indicate connection, i.e. charger connects filling for the terminal device
Electrical interface.
Step 202: terminal device is when detecting that connection status instruction is not connected, the charge switch pipe of controlling terminal equipment
Cut-off.
Wherein, above-mentioned charge switch pipe is for the charging interface of on and off terminal device and the battery of terminal device
Between access, can refer to switch Q1 in Fig. 1 and switch Q2.
In embodiments of the present invention, the processor controlling terminal equipment due to usual situation, usually inside terminal device

Cheng Zhong, by detecting the connection status of charger, so as to which this is immediately controlled when detecting that connection status instruction is not connected
The charge switch pipe of terminal device ends, and ends the access between the charging interface of terminal device and battery, so as to avoid filling
Electrical interface generates electric leakage.
In one possible implementation:
Illustratively, in conjunction with Fig. 3, as shown in figure 4, above-mentioned step 201 specifically comprises the following steps:
Step 201a1: terminal device detects charging interface during the battery charging that charger is terminal device
The discharge current of charging voltage, the voltage of battery and battery.
Step 201a2: if the charging voltage is less than or equal to the voltage of battery in predetermined amount of time and discharge current is greater than
0, then terminal device determines that the connection status instruction of charger is not connected, otherwise, it determines connection status instruction connection.
Wherein, the electric current of battery includes the power consumption electric current for being charged into electric current and terminal device of battery.
Illustratively, battery usually has voltameter circuit, and therefore, terminal device can be read in real time by voltameter circuit
Take the voltage Vbat of battery and the charge/discharge current Ibat of battery etc..In addition, the voltage Vbat of battery can also pass through terminal
The processor (for example, MCU or CPU in terminal device) of equipment reads obtain in real time, and the processor of the terminal device can be with
The charging voltage Vbus of charging interface is read in real time.
Illustratively, by taking charge construction shown in FIG. 1 as an example, it is assumed that the battery that is charged into of battery is I1, the consumption of terminal device
Electric current is I2, and resistance when charge switch pipe is connected is R, and the voltage of battery is Vbat, the charging voltage Vbus of charging interface.
Therefore so Vbus=Vbat+ (I1+I2) * R, i.e. Vbus-Vbat=(I1+I2) * R is terminal device charging in charger
In the process, if extracting charger, the battery I1 moment that is charged into for being charged into battery becomes 0A, and the electric current of battery outflow is I2, then
Vbus-Vbat=(I2) * R, at this point, R≤0 (I2) *.Therefore, Vbus-Vbat≤0 and battery outflow electric current, it is determined that charger
Connection status instruction it is not connected, Vbus-Vbat > 0, it is determined that the connection status of charger indicates connection.
In conjunction with above content, terminal device can be by determining whether the difference between charging voltage and the voltage of battery is less than
Zero, to determine the connection status of charger.
In embodiments of the present invention, terminal device can (such as 200ms) the interior charging to charging interface in the given time
The voltage and discharge current of voltage and battery carry out repeated detection, and only continuous several times detect that charging voltage is less than or equal to electricity
When the voltage and discharge current in pond are greater than 0, then determine that the connection status instruction of charger is not connected.
In embodiments of the present invention, during detecting the battery charging that charger is terminal device, pass through detection
The charging voltage of charging interface and the voltage of battery and discharge current, thus the voltage of the charging voltage of charging interface and battery and
Discharge current judges whether charger is extraction state, when detecting charger is extraction state, then the terminal is immediately controlled
The charge switch pipe of equipment ends, and ends the access between the charging interface of terminal device and battery, so as to avoid charging
Mouth generates electric leakage.
In two kinds of possible implementations:
Illustratively, in conjunction with Fig. 3, as shown in figure 5, above-mentioned step 201 specifically comprises the following steps:
Step 201b1: terminal device sends detection signal to charger.

Answer signal then continues to send detection signal, if charger determines charger not to terminal device feedback answer signal
It extracts, that is, determines that the connection status instruction of charger is not connected.
Further, in embodiments of the present invention, terminal device sends detection signal to charger according to predetermined period,
Wherein, a cycle sends at least one detection signal.It illustratively, can be with when terminal device periodicity sending detection signal
A cycle sends a detection signal, can also send multiple detection signals with a cycle.
Wherein, above-mentioned predetermined period can be user and flexibly set according to practical application scene, or one solid
Definite value, which is not limited by the present invention.
In a kind of example, terminal device sends detection by the D+/D- data line of microUSB or TypeC interface port
Signal and the answer signal for receiving charger feedback.Illustratively, by taking the D+/D- data line of TypeC interface port as an example, eventually
End equipment can send CLK signal by D+ data line, send detection signal (each instruction 8bit), example by D- data line
Such as, the transmission detection signal between CLK high period.In general, D+/D- in fast charge, there is detection signal always, sending cycle is
20ms。
Step 201b2: if terminal device does not receive the answer signal of charger feedback, it is determined that the connection shape of charger
State instruction is not connected, otherwise, it determines connection status instruction connection.
In embodiments of the present invention, terminal device do not receive charger feedback answer signal, then show charger with
Exception is connected between terminal device, so that terminal device can not receive the answer signal of charger feedback, alternatively, charger is not
Receive the detection signal.Conversely, terminal device receives the answer signal of charger feedback, then show that charger is set with terminal
It is connected between standby normal.
Further, above-mentioned step 201b2 specifically comprises the following steps:
Step A: if terminal device does not receive the answer signal of charger feedback after continuously transmitting M detection signal,
Then determine that the connection status instruction of charger is not connected, M is the integer greater than 1.
Illustratively, in order to improve accuracy in detection, terminal device can continuously transmit M to terminal device in charger
In the case that detection signal does not have answer signal, determine that charger has been extracted, determines that the connection status instruction of charger does not connect
It connects.
In a kind of example, the corresponding answer signal of M detection signal, i.e. terminal device is continuously transmitting M detection
After signal, in the case where not receiving corresponding answer signal, determine that charger has been extracted.
In another example, the corresponding answer signal of detection signal, as long as i.e. unresponsive continuous of charger
Number reaches M times, then determines that charger has been extracted.
In embodiments of the present invention, terminal device charger be terminal device battery charging during, pass through to
Charger sends detection signal, thus by determining whether charger is that terminal device feeds back answer signal, to judge charger
It whether is extraction state, when detecting charger is extraction state, then the charge switch pipe that the terminal device is immediately controlled is cut
Only, end the access between the charging interface of terminal device and battery, so as to avoid charging interface from generating electric leakage.
