Considering that the same wireless charging international standard (QI) protocol is used for wireless charging of multiple devices, the communication packets between the protocols have crosstalk, and if multiple devices are charged simultaneously, double adapter power is required, so the current wireless charging multiple devices usually use a customized input high-power adapter and two independent sets of transmitting devices.

Based on the hardware structure, the embodiment of the multi-device wireless charging method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a multi-device wireless charging method according to a first embodiment of the present invention.
In a first embodiment, the multi-device wireless charging method is applied to a wireless charging device, the wireless charging device comprises an adapter and a plurality of transmitting devices, and the multi-device wireless charging method comprises the following steps:
s10: the current transmitting device acquires an input voltage of the adapter.
It should be understood that the wireless charging device refers to a charging device connected to a terminal device to be charged without a conventional charging power line, and employs the latest wireless charging technology to transmit electric energy by using an alternating magnetic field generated between coils.
The adapter is a common adapter or a Quick Charge (QC) adapter, and the power of the adapter does not need to be customized.
Each transmitting device corresponds to a receiving end device, and the multi-device wireless charging means that a plurality of transmitting devices are utilized to realize charging of a plurality of devices.
S20: and when the input voltage is greater than a preset voltage threshold, acquiring first transmitting power required by a receiving end, and receiving second transmitting power sent by other transmitting devices.
It can be understood that the receiving end may be a mobile phone, a notebook computer, a smart watch, etc., which is not limited in this embodiment.
The preset voltage threshold can be adjusted by software, and usually the preset voltage threshold corresponding to 5V input voltage is 4.6V, the preset voltage threshold corresponding to 9V input voltage is 8.2V, and the preset voltage threshold corresponding to 12V input voltage is 11V.
It should be noted that, when a current transmitting apparatus obtains a first transmission power by receiving a Received Power (RP) packet transmitted from a receiving end, when a plurality of devices are charged simultaneously, RP packet interference may be generated, so that an RP packet interference resisting algorithm may be added. For example, when the target transmission power of the current transmitting apparatus is below 2.5W (the threshold may be fine-tuned according to the structure of the user), when the value of the first transmission power in the received RP packet is greater than the target transmission power by 0.6W, it is determined that the receiving end is removed; under the condition that the bus exists, when the RP packet detected by the current transmitting device completely corresponds to the RP packet received by the bus, the receiving end is removed, and power supply is finished.
In a specific implementation, when the adapter power is insufficient, that is, when the input voltage is smaller than a preset voltage threshold, the input voltage determines the target transmitting power. Specifically, the input power is determined according to the input voltage, the target transmitting power is determined according to the input power, and the receiving end is powered according to the target transmitting power.
S30: an input power is determined from the input voltage.
It should be noted that, in order to ensure that the adapter is not disconnected, a preset voltage threshold is set at each voltage input stage, and when the input voltage is equal to the preset voltage threshold, the transmitting device does not dynamically adjust the power according to a Control Error (CE) packet at the receiving end any more, that is, the operating frequency is not reduced or the input voltage of the full bridge is not increased or the duty ratio or the phase difference is not increased any more, but the current power parameter state is maintained; if the input voltage continues to decrease below the threshold, the full-bridge parameters (operating frequency, inverter bridge input voltage, duty cycle or phase difference) are adjusted in reverse to reduce the transmission power of the transmitting device, thereby reducing the input power of the transmitting device. When the input voltage is higher than the preset voltage threshold, the normal algorithm is recovered, i.e. the input power is dynamically adjusted through the CE packet. In essence, this function is that the input voltage participates in the PID (proportional, integral, derivative) algorithm (PID controller which controls according to the proportion (P), integral (I) and derivative (D) of the deviation in the process control) of the transmitting device, and a preset voltage threshold parameter is introduced in the general PID algorithm to control the transmitting power of the transmitting terminal.
S40: determining a maximum transmit power from the input power and the second transmit power.
It is understood that the maximum transmission power refers to the maximum transmission power that the current transmitting device can provide when powering the receiving end. When a plurality of devices are charged simultaneously, the maximum transmitting power of the current transmitting device is the difference between the input power and the second transmitting power.
It should be noted that, when the receiving end corresponding to the other transmitting apparatus is removed or the charging state is changed, the second transmitting power is changed, and therefore, the maximum transmitting power is also dynamic. Taking the receiving end as a mobile phone as an example, if the input power is 10W, and other transmitting devices supply power to the mobile phone with the second transmitting power of 5W, the maximum transmitting power of the current transmitting device is 5W. If the mobile phone enters a temperature control mechanism, the actual transmitting power of other transmitting devices is only 4W at this time, that is, the second transmitting power is 4W, then the maximum transmitting power of the current transmitting device may be 6W, and the current transmitting device may adjust its own target transmitting device to 6W, so as to utilize the power of the adapter to the maximum extent.
S50: when the maximum transmission power is larger than the first transmission power, the first transmission power is used as a target transmission power.
In a specific implementation, the target transmission power is a power supply power of a current transmitting device. When the maximum transmitting power is greater than the first transmitting power, it indicates that the current transmitting device has enough transmitting power to supply power to the receiving end, and at this time, the current transmitting device will use the first transmitting power required for charging the receiving end as the target transmitting power.
For example, if the input power of the adapter is 15W, the transmission power of other transmitting apparatuses is 10W, the maximum transmission power of the current transmitting apparatus is 5W, and the first transmission power required by the receiving end of the current transmitting apparatus is 3W, the receiving end is powered by 3W as the target transmission power.
S60: and supplying power to the receiving end according to the target transmitting power.
It can be understood that the current transmitting apparatus powers the receiving end according to the target transmitting power, so as to implement wireless charging of the receiving end.
Certainly, the above situation is a case with a bus, and if only GPIO (General Purpose Input/Output) communication is available without the bus and specific power information cannot be obtained, a threshold may be set, for example, the target transmit power of the transmitting device is set to be higher than 8W and lower than 8W, when the high power is higher, the GPIO is set to be lower when the low power is lower, and other transmitting devices detect the GPIO of the other transmitting device to adjust the target transmit power of the transmitting device, and also set the GPIO of the transmitting device according to the target transmit power of the transmitting device. For example, when the opposite side is detected to be high power, the target transmission power of the opposite side is limited to be common power, and when the opposite side is detected to be low power, the target transmission power of the opposite side is not limited, and the high power of quick charging can be entered.
The embodiment obtains the input voltage of the adapter through the current transmitting device; when the input voltage is greater than a preset voltage threshold, acquiring first transmitting power required by a receiving end, and receiving second transmitting power sent by other transmitting devices; determining an input power according to the input voltage; determining a maximum transmit power from the input power and the second transmit power; when the maximum transmission power is larger than the first transmission power, taking the first transmission power as a target transmission power; and the receiving end is powered according to the target transmitting power, so that the communication among transmitting devices is increased, the transmitting power is dynamically distributed, an adapter does not need to be customized, the utilization rate of the adapter is effectively improved, and the cost of the multi-device wireless charging equipment is saved.
Further, as shown in fig. 3, a second embodiment of the multi-device wireless charging method according to the present invention is proposed based on the first embodiment, and in this embodiment, step S50 specifically includes:
s501: and when the maximum transmitting power is larger than the first transmitting power, acquiring a control error packet from a receiving end.
It is understood that the value of the CE packet may be 0, negative or positive. The value of the CE packet is 0 when the actual control point coincides with the expected control point, negative when the transmission power needs to be reduced, and positive when the transmission power needs to be increased.
It should be noted that, when multiple devices are charged simultaneously, there may be a case where CE packets interfere, and therefore, a CE packet interference rejection algorithm may be added. For example, the CE timer out parameter is determined and changed to not be the timer out as long as the header flag preamble exists; two identical CE packets are received in succession for power adjustment, etc.
S502: and adjusting the target transmission power to the first transmission power according to the control error packet.
To more accurately control the target transmit power, the target transmit power is typically adjusted to the first transmit power based on a PID algorithm based on the CE packets.
In the specific implementation, the first transmitting power is introduced into a PID algorithm as a variable, and the target transmitting power is enabled to reach the first transmitting power by adjusting the operating frequency, the inverter bridge input voltage, the duty ratio or the phase difference.
In the embodiment, the CE packet is acquired from the receiving end, and the target transmitting power is adjusted to the first transmitting power according to the control error packet, so that the target transmitting power is dynamically adjusted, the utilization rate of the adapter is effectively improved, and the cost of the multi-device wireless charging device is saved.
Further, as shown in fig. 4, a third embodiment of the multi-device wireless charging method according to the present invention is proposed based on the first embodiment, and in this embodiment, after step S40, the method further includes:
s50': and when the maximum transmitting power is smaller than the first transmitting power, judging the power supply priority with other transmitting devices.
It should be understood that, in order to make the best use of the power of the adapter, there are several algorithms, such as the priority fast charging of the first-charged device, the priority fast charging of the apple device, or the priority fast charging of the samsung device. Therefore, when the maximum transmission power is smaller than the first transmission power, the power supply priority with other transmitting apparatuses may be determined according to the power supply time or the ID of the receiving end.
When the power supply priority is judged according to the power supply time, if the power supply time of the current transmitting device is longer, the power supply priority is higher if the power supply time of the current transmitting device is longer than that of other transmitting devices, and the power supply of the current transmitting device is preferentially ensured.
When the power supply priority is judged according to the ID of the receiving end, if the receiving end corresponding to the current transmitting device is an apple device or a samsung device, the power supply priority of the current transmitting device is higher, and the power supply of the current transmitting device is preferentially ensured.
S60': and when the power supply priority is lower, taking the maximum transmission power as a target transmission power.
It can be understood that if the power supply priority of the current transmitting device is lower, the transmitting power is preferentially provided for other transmitting devices, and the current transmitting device is only powered according to the maximum transmitting power.
And when the power supply priority is higher, preferentially providing the transmitting power for the current transmitting device, and at the moment, the current transmitting device takes the first transmitting power as the target transmitting power to supply power to the receiving end.
For example, the input power of the adapter is 15W, the transmission power of other transmitting devices is 10W, the maximum transmission power of the current transmitting device is 5W, and the first transmission power required by the receiving end of the current transmitting device is 6W, the power supply priority of the transmitting device needs to be determined, if the receiving end of the current transmitting device is an apple device, the power supply priority of the current transmitting device is higher, the current transmitting device is provided with 6W of target transmission power to be preferentially powered, and if the power supply priority of the current transmitting device is lower, only 5W of target transmission power is provided for the current transmitting device, so that the power supply of other transmitting devices is preferentially guaranteed.
In the embodiment, when the maximum transmitting power is smaller than the first transmitting power, the power supply priority of other transmitting devices is judged, when the power supply priority is lower, the maximum transmitting power is used as the target transmitting power, and when the power supply priority is higher, the first transmitting power is used as the target transmitting power to supply power to the receiving end, so that the adapter power is utilized to the maximum extent dynamically, and the cost of the multi-device wireless charging equipment is saved.
In addition, as shown in fig. 5, a functional module diagram of a first embodiment of the multi-device wireless charging system according to the present invention is provided based on the first embodiment. In this embodiment, the multi-device wireless charging system includes:
