step 301, after the tablet computer 100 detects that the first charging interface of the tablet computer 100 is connected to the first charger, power is supplied to the keyboard 200 connected to the tablet computer 100 through the tablet computer 100; the keyboard 200 is connected to the tablet pc 100 through pogo pins.
Specifically, referring to fig. 1, the first charging interface of the tablet computer 100 may be a Type-C interface of the tablet computer 100. The first charger may be a Type-C interface-plugged charger of the tablet computer 100.
Specifically, the power supply to the keyboard 200 connected to the tablet computer 100 through the tablet computer 100 may be: after the first charging interface is connected with the first charger, the tablet computer 100 determines that a first switch between the first charging interface and a fast charging chip of the tablet computer 100 is in a closed state; closing a third switch between the pogo pin of the tablet computer 100 and the boost circuit of the tablet computer 100; and supplying power to the keyboard through the booster circuit.
The first switch is the switch S1, the third switch is the switch S3, and the Boost circuit of the tablet pc 100 is a Boost circuit. That is, after the Type-C interface of the tablet computer 100 is plugged into the charger, the switches S1 and S3 are in the closed state, and the switches S2 and S4 are in the open state. The charger on the tablet pc 100 charges the battery of the tablet pc 100 while the Boost circuit is in operation to power the connected keyboard 200.
In step 302, the tablet pc 100 receives the second charger type and the second charging power of the second charger sent by the keyboard 200 through the pogo pin, and obtains the first charger type and the first charging power of the first charger.
The second charger type and the second charging power are identified after the keyboard 200 detects that the second charging interface of the keyboard 200 is connected with the second charger, and the second charger type and the second charging power are obtained and then sent to the tablet computer 100.
Specifically, referring to fig. 1, the second charging interface of the keypad 200 may be a Type-C interface of the keypad 200. The second charger may be a Type-C interface plugged charger of the keypad 200.
In particular, when the Type-C interface of the keyboard 200 is plugged into the charger, the power management module of the keyboard 200 detects and identifies the second charger plug-in event, identifies the charger Type and charging power of the second charger, and transmits the charger Type and charging power of the second charger to the power management module of the tablet pc 100 through the pogo pin data transmission channel.
In step 303, the tablet pc 100 determines a charging path of the tablet pc 100 and a power supply path of the keyboard 200 according to the first charger type, the first charging power, the second charger type and the second charging power.
Specifically, the determining, by the tablet computer 100 according to the first charger type, the first charging power, the second charger type, and the second charging power, the charging path of the tablet computer 100 and the power supply path of the keyboard 200 may be: if the second charger is a non-standard charger, or the first charger and the second charger are both standard chargers and the first charging power is greater than or equal to the second charging power, determining that the tablet computer 100 uses the first charger for charging and the keyboard 200 uses the second charger for supplying power; if the first charger is a non-standard charger and the second charger is a standard charger, or the first charger and the second charger are both standard chargers and the first charging power is less than the second charging power, it is determined that the tablet computer 100 uses the second charger to charge and the keyboard 200 uses the second charger to supply power.
Further, it is determined that the tablet pc 100 is charged using the first charger, and after the keyboard 200 is powered using the second charger, the tablet pc 100 may close a Boost (Boost) circuit of the tablet pc 100 and turn off the third switch (S3).
Further, after determining that the tablet computer 100 is charged by using the second charger and the keyboard 200 is powered by using the second charger, the tablet computer 100 may close the boost circuit of the tablet computer 100, open the first switch (S1) and the third switch (S3), and close the second switch (S2) between the fast charging chip (SC chip) and the pogo pin of the tablet computer 100; transmitting a control command for closing the fourth switch (S4) to the keyboard 200 through the pogo pin, so that the keyboard 200 closes the fourth switch; the fourth switch is a switch between the pogo pin of the keyboard 200 and the second charging interface. In particular, after the keyboard 200 receives a control command to close the fourth switch, the power management module of the keyboard 200 may close the switch S4 by configuring a general-purpose input/output (gpio) port level specified on the MCU of the keyboard 200.
In the above method for determining the charging path, after the tablet computer 100 detects that the first charging interface of the tablet computer 100 is connected with the first charger, the tablet computer 100 supplies power to the keyboard 200 connected with the tablet computer 100, receives the second charger type and the second charging power of the second charger sent by the keyboard 200 through the pogo pin, and obtains the first charger type and the first charging power of the first charger, so as to determine the charging path of the tablet computer 100 and the power supply path of the keyboard 200 according to the first charger type, the first charging power, the second charger type and the second charging power. Therefore, when the keyboard is matched with the tablet personal computer for use, and the tablet personal computer 100 is inserted into the charger first, and the keyboard 200 is inserted into the charger later, the power supply path of the keyboard 200 and the charging path of the tablet personal computer 100 can be determined.

In another implementation, after the tablet computer 100 is charged by using the second charger, and the keyboard 200 is powered by using the second charger, if the user pulls out the first charger connected to the tablet computer 100, the current state is maintained unchanged, that is, the tablet computer 100 continues to use the second charger to charge, and the keyboard 200 continues to use the second charger to supply power.
The embodiment can realize that when the keyboard 200 is matched with the tablet computer 100 and the keyboard 200 and the tablet computer 100 are both inserted into the charger, the power supply path of the keyboard 200 and the charging path of the tablet computer 100 are determined when the charger of the tablet computer 100 is pulled out.

Step 502, power is supplied to the keyboard 200 through the boost circuit.
That is, after determining that the tablet computer 100 is charged using the first charger and the keyboard 200 is powered using the second charger, if the power management module of the keyboard 200 detects a second charger unplugged event of the keyboard 200, the second charger unplugged event is transmitted to the power management module of the tablet computer 100 through the pogo pin data channel. After receiving the second charger unplugged event on the keyboard 200, the power management module of the tablet computer 100 enables the Boost circuit to operate by configuring the gpio port level specified on the SOC of the tablet computer 100, and closes the switch S3. The tablet 100 may then power the keyboard 200 via the Boost circuit described above.

Specifically, the power management module of the keyboard 200 detects the second charger unplugged event and then sends the second charger unplugged event to the power management module of the tablet pc 100 through the pogo pin data channel. In order to ensure that the keyboard 200 is not powered down instantaneously when the second charger is pulled out and achieve the purpose of switching the service without interruption, a power-down protection circuit on the side of the keyboard 200 is needed to ensure that the service is not interrupted in the process of switching the access.

In addition, the power management module of the keyboard 200 may turn off the switches S2 and S4 by configuring the gpio port level specified on the MCU of the keyboard 200.
