When the power supply voltage is higher than the current voltage, an adjustment command for increasing the power supply is transmitted, and when the power supply voltage is lower than the current voltage, an adjustment command for decreasing the power supply is transmitted.

In some embodiments, the third charging assembly 60 is further configured to receive a power supply data packet transmitted by the charging module 100;

wherein, the power supply data packet includes:

an adjustment instruction for notifying the power supply apparatus 200 to increase the power supply or decrease the power supply;

And/or the number of the groups of groups,

And adjusting parameters for the power supply apparatus 200 to determine the target power.

The third charging assembly 60 may receive the power data packet transmitted from the first charging assembly 30 in the charging module 100. The third charging component 60 may identify adjustment instructions and/or adjustment parameters in the power supply data packet.

When the adjustment command is to increase the power supply, the third charging assembly 60 increases the power supply provided to the first charging assembly 30. When the adjustment command is to reduce the power supply, the third charging assembly 60 reduces the power supply to the first charging assembly 30.

When the adjustment parameter carries a specific target power, the third charging component 60 may provide the corresponding target power to the first charging component 30.

In one embodiment, when the power supply data packet only includes the adjustment command, the power supply device may adjust the power supply according to the increase power supply or the decrease power supply in the adjustment command. The power supply equipment and the charging equipment preset step parameters, and when the power supply equipment receives a data packet for increasing the power supply power, the current sum of the power supply power and the step is taken as the target power to supply power. When the power supply equipment receives the data packet for reducing the power supply power, the current difference between the power supply power and the step size can be used as the target power for power supply.

An embodiment of the present disclosure provides a power supply method, as shown in fig. 6, including:

s210: receiving power supply power sent by a charging module, wherein the power supply power is determined according to the current voltage of a battery module;

s220: and determining the electric energy of the transmitted wireless charging signal according to the power supply power, wherein the electric energy is used for charging the battery module.

The power supply method in the present disclosure can be applied to the power supply module.

In the process of charging the battery module, wireless communication is established between the power supply module and the charging module until the charging is finished. The power supply module can receive the power supply sent by the charging module, and the power supply is used for charging the battery module connected with the charging module.

The power supply is not fixed, but is dynamically adjusted according to the current voltage of the battery module.

When the power supply module receives the power supply power of the charging module, the power supply module can convert the power supply power into electric energy of a wireless charging signal, so that the electric energy is transmitted to the charging module, and the function of charging the battery module is realized.

In some embodiments, as shown in fig. 7, the method further comprises:

s230: receiving a power supply data packet transmitted by the charging module;

s240: determining the power supply data packet as an adjustment instruction and/or an adjustment parameter;

S250: when the power supply data packet is the adjustment instruction and the adjustment instruction is to increase the power supply, increasing the electric energy of the transmitted wireless charging signal;

S260: and when the power supply data packet is the adjustment instruction and the adjustment instruction is to reduce the power supply power, reducing the electric energy of the transmitted wireless charging signal.

It will be appreciated that, during the charging process, when the power supply module receives the power supply data packet transmitted by the charging module, it may be determined whether the data in the power supply data packet can be identified. When the data in the power packet can be identified, it may be determined whether the power packet is an adjustment instruction or an adjustment parameter.

When the power supply data packet is an adjustment instruction and the adjustment instruction is to increase the power supply, the power of the wireless charging signal is correspondingly increased to meet the requirement of increasing the power supply. When the power supply data packet is an adjustment instruction and the adjustment instruction is to reduce the power supply, the power of the transmitted wireless charging signal is correspondingly reduced to meet the requirement of reducing the power supply.

In one embodiment, when the adjustment command starts with a positive sign and carries a specific adjustment parameter, the corresponding adjustment parameter is correspondingly increased on the current power as the target power. When the adjustment instruction starts with a negative sign and carries a specific adjustment parameter, the corresponding adjustment parameter is correspondingly reduced on the current power as the target power.

In some embodiments, the method further comprises:

It can be appreciated that when the power supply data packet is determined as the adjustment parameter, and the adjustment parameter has the target power, the electric energy of the corresponding wireless charging signal can be transmitted according to the target power.

The embodiment of the disclosure provides a charging structure, which has three parts, wherein the first part is an adapter (for example, a charging head), the second part is a power supply module (for example, a wireless charging seat of a watch), the third part is a power supply module, and the power supply module is a component part of the watch.

The adapter in the embodiment of the disclosure can be understood as a charging head, the power supply module can be a wireless charging seat of a watch, and the electronic device can be the watch.

When charging, the adapter (charging head) is inserted on the charger (power strip), the power supply module is inserted on the adapter, the power supply module is contacted with the power supply module, the power supply module and the power supply module are coupled through a magnetic field between the Tx/Rx coils, and the Tx can charge the watch. The Tx chip is provided with a second coil of the power supply module, and the Rx chip is provided with a first coil of the charging module. The charging module is also connected with the battery module of the watch.

The power supply module can be internally provided with a third control component (a charging protocol chip), can control the output voltage of an adapter supporting a quick charging protocol (supporting QC or PD protocol) through CC1/CC2 and D+D-, and can control the output voltage of the adapter through the third control component (the protocol chip).

When adjusting power between Tx/Rx, not only can the power output between Tx/Rx be changed by frequency modulation, duty cycle modulation, but also the power output between Tx/Rx can be changed by adjusting the output voltage.

If the power supply module is not provided with a third control component (a charging protocol chip), the adjustment of the output power between Tx and Rx can only be realized by adjusting the frequency and the duty ratio, so that the power supply efficiency between Tx and Rx is poor.

During charging, tx/Rx performs wireless power output on Rx by magnetic field coupling between coils and by conforming to the QI protocol standard. QI is a wireless charging standard proposed by the wireless charging alliance (Wireless Power Consortium, abbreviated as WPC), and has the characteristics of convenience and universality.

The power supply power of the Rx output power supply Voltage (VBUS) is changed, and through QI standard, tx can output corresponding power by means of voltage regulation, frequency modulation or duty cycle regulation according to the communication requirement (CEP packet) of Rx.

The power supply Voltage (VBUS) is directly charged to the battery module through a second charging assembly (charging chip) of the charging module, and the current voltage and current of the battery module can be monitored in real time by the acquisition assembly (fuel gauge) and transmitted to the first control assembly (MCU).

The first control component (MCU) receives data of the acquisition component (fuel gauge) in real time through the communication bus (I2C), or controls the first charging component (Rx chip) to output corresponding power supply Voltage (VBUS), controls the second charging component (charging chip) to charge and the like.

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). The first control component (MCU) can control the first charging component (Rx chip) to output corresponding power supply voltage in real time according to the collected current voltage and current, and the power supply voltage adjustment of the first charging component can bring about the change of the power supply power of the first charging component, and then the third charging component (Tx) can provide dynamic power adjustment through QI standard.

As shown in fig. 2, in the CC stage, the supply Voltage (VBUS) is dynamically adjusted in real time, so that the voltage difference between the supply Voltage (VBUS) and the current voltage of the battery module is small, that is, the supply voltage follows the current voltage. The current of the battery is detected in real time through the acquisition component, the current is ensured to be within the safety range of the battery module, if the current is smaller than a set interval, the power supply voltage is increased, and if the current is larger than the set interval, the power supply voltage is reduced.

The power supply voltage can also be kept following in a preset period of the CV stage, wherein the preset period is a period when the current is greater than the current threshold I. The current threshold I may be measured or estimated by measuring the supply voltage (VBUS-V (cut-off))/R, where R is the impedance loss of the supply Voltage (VBUS) in the whole line. When the current is smaller than the current threshold I, the power supply Voltage (VBUS) stops following and is switched to constant voltage charging until the battery module is charged.

Since the feedback of wireless charging is not as fast as the feedback of wired charging, the supply voltage follows more slowly, even in part in a staircase.

Through the charging structure and the strategy, the loss in the charging path can be reduced, so that the charging efficiency is improved, and the charging with higher power and faster speed is realized.
