It is understood that the second power supply device may be classified into a device supporting dynamic voltage regulation and a device not supporting dynamic voltage regulation.

Before providing the supply voltage to the second power supply device, it is necessary to determine whether the second power supply device supports dynamic voltage regulation. If the second power supply device supports dynamic voltage regulation, the power supply voltage may be adjusted in real time to provide the dynamic power supply voltage to the second power supply device.

When the second power supply equipment supports dynamic voltage regulation, the rapid charging function of the battery module can be realized.

In some embodiments, the providing the supply voltage to the second power supply device comprises:

It will be appreciated that the second power supply device does not support dynamic voltage regulation, and the second power supply device is a fixed voltage output.

The power supply method applied to the first power supply equipment can be compatible with a scheme of fixing voltage and dynamically adjusting power supply voltage, so that a user can select a second power supply equipment supporting dynamic voltage adjustment or not supporting dynamic voltage adjustment to supply power in a charging process.

The embodiment of the disclosure provides a charging structure, which comprises three parts, wherein the first part is a charging module (for example, a watch part), the second part is a first power supply device (for example, a wired charging seat), and the third part is a second power supply device (for example, a charging head).

When charging, the second power supply equipment is inserted on the charger (power strip), the first power supply equipment is inserted on the second power supply equipment, the charging module is placed on the first power supply equipment, and the first power supply equipment is in contact with the first connecting component (metal contact) of the charging module through the third connecting component (pogo pin) to charge the watch.

The first power supply device is internally provided with a first power supply component (a charging protocol chip), a second power supply device (a charging head, QC (quick charging) or PD (quick charging)) supporting a quick charging protocol can be controlled through CC1/CC2 and D+D-, and the output voltage (namely the power supply voltage) of the second power supply device (the charging head) can be controlled through the first power supply component (the protocol chip). The protection component (OVP/OCP/UVLO chip) of the first power supply device (charging seat) is a protection circuit, and the output voltage (namely the power supply voltage) of the second power supply device (charging head) is output to the third connection component (pogo pin) after passing through the whole protection circuit.

When charging, the third connecting component (pogo pin) is in contact with the first connecting component (watch metal contact) of the charging module, and the output voltage VBUS (i.e. the supply voltage) of the second power supply device (charging head) is directly charged to the input end of the first charging component (charging chip of the watch) of the charging module.

The control unit of the first power supply component (protocol chip) can support General-purpose input/output protocol (GPIO) or I2C communication, and the like, and is conducted to the first control component (MCU) through the fourth connection component (pogo pin), and the first control component (MCU) controls the first power supply component (protocol chip) through GPIO/I2C, so that the fourth connection component outputs a predetermined voltage (i.e., a power supply voltage).

The power supply Voltage (VBUS) is directly charged to the battery module through the first charging assembly (charging chip). The acquisition component (electricity meter) is responsible for detecting the current voltage and current of the battery module in real time and transmitting the current voltage and current to the first control component (MCU).

The first control component (MCU) can receive the data acquired by the acquisition component or control the first charging component (charging chip) to charge in real time through the communication bus (I2C).

In one embodiment, the first power supply assembly (protocol chip) can be controlled in real time through the first control assembly (MCU), so that the second power supply device (charging head) is controlled to output the power supply voltage required by the first control assembly (MCU); the first control component (MCU) can read the current voltage of the battery module and the current of the battery module in real time through the acquisition component (fuel gauge);

As shown in fig. 2, in the CC stage, the power supply Voltage (VBUS) is dynamically adjusted in real time, so that the voltage difference between the power supply Voltage (VBUS) and the current voltage of the battery module is small, that is, the following effect is achieved. Meanwhile, the current of the battery module is detected in real time, the current is ensured to be within the safety range of the battery module, if the current is smaller than a first threshold value, the power supply voltage is increased, and if the current is larger than a second threshold value, the power supply voltage is reduced, wherein the first threshold value is smaller than the second threshold value.

The preset period of the CV stage may keep the supply voltage following the current voltage of the battery module, where the preset period is that the current of the battery module is greater than the preset current I, where the preset current I may be actually measured or estimated, and the actually measured preset current I is the supply voltage (VBUS-V (cut-off))/R, where R is the actually measured VBUS total line impedance loss. When the current is smaller than the preset current I, the power supply current Voltage (VBUS) stops following, and the constant voltage charging is switched to be performed until the charging of the battery module is finished.

When the second power supply equipment (charging head) does not support dynamic voltage regulation output, the power supply Voltage (VBUS) goes through the traditional method, and a fixed voltage is output to charge the battery module.

Through the power supply framework, loss in a charging path can be reduced, efficiency can be greatly improved, and charging can be performed more quickly and with higher power.
