technical field

The present application belongs to the field of communication technologies, and in particular relates to a charging method, a charging device and a charger.

Background technique

At present, the functions of terminals are becoming more and more powerful, but the problem of serious power consumption has also followed; when users pay more and more attention to the standby time, increasing the battery capacity is the first solution that mobile phone manufacturers think of. When battery technology cannot be conquered, fast charging solutions emerge as the times require. At present, fast charging technology is a charging method commonly used by mobile phone manufacturers. Among them, the more commonly used fast charging protocols include Power Delivery (PD) charging protocol, Pump Express (PE) charging protocol, and fast charging ( Quick Charge, QC) charging protocol, fast charging protocol (Fast Charge Protocol, FCP), super charging protocol (Super Charge Protocol, SCP), flash charging protocol (VOOC) and other charging protocols. Among them, some charging protocols are universal fast charging protocols, such as PD charging protocols, while others are private charging protocols customized by mobile phone manufacturers based on their own mobile phones. Such private charging protocols can make the fast charging function more suitable. Your own mobile phone is also more secure.

In order to apply multiple fast charging protocols as much as possible, some fast charging chargers, mobile power supplies and other products support multiple fast charging protocols. For example, a charger supports QC charging protocol, PD charging protocol and other fast charging protocols, and supports QC The communication between the mobile phone of the charging protocol and the charger can carry out the fast charging communication of the QC charging protocol, and the communication between the mobile phone supporting the PD charging protocol and the charger can carry out the fast charging communication of the PD charging line protocol, thus increasing the applicability of the charger ; Some mobile phones also support a variety of fast charging protocols. For example, mobile phones support both the fast charging method of the QC charging protocol and the fast charging method of the PD charging protocol; the charger that supports the PD charging protocol is connected to the fast charging protocol of the PD charging protocol. Fast charging is performed in the charging mode, and the charger that supports the QC charging protocol is connected to perform fast charging according to the QC charging protocol, thereby increasing the charging experience of the mobile phone.

However, when a fast-charging mobile phone that supports a private protocol communicates with a charger that supports multiple fast-charging protocols, the intention is to give priority to identifying the private fast-charging protocol, but due to the communication of some charging protocols (such as PD charging protocol, QC charging protocol, etc.) The speed is relatively fast. After the mobile phone is connected to the charger, the communication of the PD and other charging protocols is prioritized, and the fast charging is carried out according to the communication methods of the PD and other charging protocols, which undoubtedly reduces the usability of the private charging protocol and reduces the charging time. safety.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and distinguish between "first", "second", etc. The objects are usually of one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The charging method, the charging device, and the charger provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 1 , which is a schematic flowchart of a charging method according to an embodiment of the present application. As shown in FIG. 1 , an embodiment of the present application provides a charging method, which can be applied to a charger, and the charging method may include:

Step 11: Within the first preset time period after the charger and the powered device are connected, if the charger and the powered device meet the handshake conditions of the second charging protocol, the powered device is charged according to the second charging protocol. If the handshake condition of the second charging protocol is not satisfied, the power receiving device is charged according to the first charging protocol after the first preset time period; wherein the handshake communication rate of the first charging protocol is faster than that of the second charging protocol.

In this embodiment of the present application, the determination of whether to connect with a powered device can be determined by: whether an Rd resistance (ie, a pull-down resistor) is detected. After connecting with the power receiving device, because the handshake communication rate of the first charging protocol is faster than that of the second charging protocol, it means that in the prior art, the power receiving device will be firstly communicated with the power receiving device according to the first charging protocol, and then according to the second charging protocol. A charging protocol charges the power receiving device. However, in the embodiment of the present application, a time period, that is, a first preset time period, is firstly set, and within the first preset period of time, it is detected whether the handshake of the second charging protocol is satisfied. Condition, if the handshake condition that satisfies the second charging protocol is detected within the first preset time period, handshake and communicate with the power receiving device according to the second charging protocol, and then charge the power receiving device according to the second charging protocol. If the handshake condition that satisfies the second charging protocol is not detected within the first preset time period, the power receiving device can be charged according to the first charging protocol after the first preset time period. The time for the first charging protocol to complete the handshake communication with the power receiving device and charging the power receiving device. Therefore, under the premise of hardly affecting the charging response time of the connection with the power receiving device, it is first to detect whether the handshake condition of the second charging protocol is satisfied. , so that the usage rate of the second charging protocol can be improved, and the safety during charging can be improved.

It should be noted that, within the first preset time period, even if the handshake communication rate of the first charging protocol is fast, the handshake communication with the power receiving device will not be completed according to the first charging protocol, and the power receiving device will not be completed according to the first charging protocol. For charging, a first preset duration is reserved to detect whether the handshake conditions of the second charging protocol are met. After the first preset duration is exceeded, and the second charging protocol is not detected, the The first charging protocol completes handshake communication with the powered device and charges the powered device according to the first charging protocol.

In this embodiment of the present application, the charger and the powered device may support multiple charging protocols, including a first charging protocol and a second charging protocol, where the first charging protocol may be a charging protocol with a fast handshake communication rate set, such as PD charging protocol, PE charging protocol, QC charging protocol, etc., and the second charging protocol can be a private charging protocol, such as FCP charging protocol, SCP charging protocol, VOOC charging protocol, etc. Since the private charging protocol sets the mobile phone manufacturer's own production The protection measures of the terminal are more secure, so the charging of the power receiving device by preferentially using the second charging protocol can ensure the security of charging.

In the embodiment of the present application, within the first preset time period after the charger and the power receiving device are connected, if the charger and the power receiving device meet the handshake conditions of the second charging protocol, the power receiving device will be charged according to the second charging protocol. to charge, including:

Delay sending the first handshake request to the powered device according to the first charging protocol;

receiving at least one hard reset signal sent by the powered device according to the first charging protocol;

When the preset conditions are met, if the charger and the powered device satisfy the handshake condition of the second charging protocol, the communication signal of the first charging protocol is shielded, and the powered device is charged according to the second charging protocol.

In the embodiment of the present application, since the handshake communication rate of the first charging protocol is faster than that of the second charging protocol, in order to delay the moment when the charger completes handshake communication with the power receiving device and performs charging according to the first charging protocol, After the device is connected, the sending of the first handshake request to the powered device can be postponed (while in the prior art, the first handshake request is sent to the powered device according to the first charging protocol immediately after the powered device is connected), because the receiver The electrical device does not receive the first handshake request within a certain period of time, which will trigger the powered device to send a hard reset signal to the charger (for example, in the PD charging protocol, if the powered device cannot receive the first handshaking request sent by the charger, A handshake request will trigger the powered device to send a hard reset signal, causing a delay), and the charger will thus receive at least one hard reset signal sent by the powered device according to the first charging protocol; It is in the process of handshake communication, but the handshake communication has not been completed, so it will not directly charge the power receiving device according to the first charging protocol, so that it can be detected within the first preset time period whether it meets the requirements of the second charging protocol. The handshake condition is to communicate with the power receiving device according to the second charging protocol, and after the handshake communication is completed, the power receiving device is charged according to the second charging protocol; if the handshake meeting the second charging protocol is not detected within the first preset time period. condition, after the first preset time period elapses, the charger sends a first handshake request to the powered device according to the first charging protocol, and then completes handshake communication with the powered device, and then performs a handshake communication with the powered device according to the first charging protocol. Charge.

In this embodiment of the present application, the preset condition is that the number of times of the received hard reset signal is less than the preset number of times, or the preset condition is that the hard reset signal is received for the first time within a second preset time period.

In an optional embodiment, the preset condition is that the number of received hard reset signals is less than the preset number of times, and the preset number of times is a positive integer. For example, when the first charging protocol is the PD charging protocol, the preset number of times is a positive integer. The number of times is set to 3, that is to say, if the first handshake request sent by the charger is not received, the power receiving device will be triggered to send three hard reset signals in turn, and the first preset duration is the same as the power receiving device. From the moment of connection to the moment of receiving the third hard reset signal, before the third hard reset signal is received, it is possible to check whether the handshake conditions of the second charging protocol are met within this time period. , when it is satisfied, handshake and communicate with the power receiving device according to the second charging protocol and charge the power receiving device. At this time, the communication signal of the first charging protocol can be ignored or shielded, but if the third hard reset is received After the signal, the handshake condition that meets the second charging protocol is still not detected. In order to ensure the fast response of charging, the charger sends a first handshake request to the power receiving device according to the first charging protocol, and completes handshake communication with the power receiving device. The powered device is charged according to the first charging protocol to ensure that the powered device can still be charged relatively quickly.

In another optional implementation manner, the end time may be within a second preset time period after the hard reset signal is received for the first time, for example, when the first charging protocol is a PD charging protocol, although the protocol stipulates The hard reset signal triggered three times, but in actual scenarios, many manufacturers do not set the terminal (ie, the power receiving device) to trigger the hard reset signal three times according to the standard. Therefore, in order to avoid receiving the third hard reset signal for a long time As a result of not being able to be charged, the embodiment of the present application adds a waiting time, that is, the second preset time, that is, after the first hard reset signal is received, the second preset time elapses. Here In this case, the first preset duration is from the moment of connection with the power receiving device to the moment when the second preset duration is reached after receiving the first hard reset signal. During this period, it is possible to detect whether the The handshake condition of the second charging protocol is satisfied, and when it is satisfied, it handshakes and communicates with the power receiving device according to the second charging protocol and charges the power receiving device, then the communication signal of the first charging protocol can be ignored or shielded. If the subsequent hard reset signal is not received within the preset time period, a first handshake request is sent to the power receiving device according to the first charging protocol, a handshake communication is established with the power receiving device, and the mode of charging according to the first charging protocol is entered.

In other embodiments of the present application, optionally, within a first preset time period after the charger and the power receiving device are connected, if the charger and the power receiving device meet the handshake conditions of the second charging protocol, then The second charging protocol charges the powered device, including:

Within the first preset time period, the following operations are repeated: sending a first handshake request to the powered device according to the first charging protocol, and after receiving the first reply signal sent by the powered device in response to the first handshake request and the power request In this case, send a soft reset signal and a first handshake request to the powered device;

Within the first preset time period, if the charger and the powered device meet the handshake conditions of the second charging protocol, the communication signal of the first charging protocol is shielded, and the powered device is charged according to the second charging protocol.

In the embodiment of the present application, since the handshake communication rate of the first charging protocol is faster than that of the second charging protocol, in order to delay the moment when the charger completes handshake communication with the power receiving device and performs charging according to the first charging protocol, After the device is connected, the following operations may also be repeated within the first preset duration: sending a first handshake request to the powered device according to the first charging protocol, and the powered device will send a first reply signal in response to the first handshake request and a power request, wherein the first reply signal is used to indicate that the first handshake request sent by the charger has been received, and the power request is used to request the charger for the power level required by the powered device itself, according to the prior art. In other words, under the first charging protocol (such as the PD charging protocol), the charger needs to reply with a second reply signal, indicating that the charger has received the power request, and can charge the powered device with the requested power according to the first charging protocol. Charge, but in this embodiment of the present application, in order to strive for a time window for detecting whether the handshake condition of the second charging protocol is met, the charger does not send the second reply signal, but sends the soft reset signal and the first handshake request in sequence. If the powered device does not receive the second reply signal, the communication between the charger and the powered device is not completely established, and because the first handshake request is received, the powered device will respond to the first handshake request again. Send the first reply signal and the power request, so that the handshake communication process between the charger and the power receiving device has been looping for a certain period of time in the above two steps, that is, the first preset time period of the loop, during this period, you can Detecting whether the handshake condition of the second charging protocol is satisfied, and when satisfied, handshakes and communicates with the power receiving device according to the second charging protocol and charges the power receiving device, then the communication signal of the first charging protocol can be ignored or shielded.

In the embodiment of the present application, if the handshake condition of the second charging protocol is not satisfied, the power receiving device is charged according to the first charging protocol after the first preset time period, including:

If the charger and the powered device do not meet the handshake conditions of the second charging protocol within the first preset time period, after the first preset time period exceeds the first preset time period, the powered device is charged according to the first charging protocol in response to a power request.

That is to say, after the cycle of the above operation exceeds the first preset time period, the handshake condition that meets the second charging protocol is still not detected, then the charger will follow the normal process, after receiving the first reply signal and power request, A second reply signal is sent to the powered device, indicating that the power request has been received, and the powered device is charged with the requested power according to the first charging protocol.

In the embodiment of the present application, if the handshake condition of the second charging protocol is not satisfied, after the step of charging the power receiving device according to the first charging protocol after the first preset time period, the method further includes:

If it is detected that the handshake condition of the second charging protocol is satisfied, the charging of the power receiving device according to the first charging protocol is stopped, and the charging of the power receiving device according to the second charging protocol is switched.

Since the handshake condition that satisfies the second charging protocol is not detected within the first preset time period, in order to ensure timely charging of the power receiving device, after the first preset time period, the power receiving device will be charged according to the first charging protocol ; After that, it can continue to detect whether the handshake conditions of the second charging protocol are met, and when it is detected that the handshake conditions of the second charging protocol are met, the communication of the first charging protocol is shielded, and the receiver is stopped according to the first charging protocol. The electrical device is charged, and in response to the handshake communication of the second charging line protocol, the powered device is charged according to the second charging protocol.

In the embodiment of the present application, for the second charging protocol, in detecting whether the handshake condition of the second charging protocol is satisfied, the handshake condition for satisfying the second charging protocol may be that the voltage value between D+/D- is greater than or equal to the preset value voltage threshold, correspondingly, the handshake condition that does not meet the second charging protocol may be that the voltage value between D+/D- is less than the preset voltage threshold; when the detection is performed within the first preset time period, D+/D can be detected multiple times -The voltage value between - to ensure the accuracy of the detection results, the detection time interval can be periodic or aperiodic; when the detection is performed after the first preset time period is exceeded, optional Tests at certain intervals.

In the embodiment of the present application, during the charging process, the second charging protocol is identified first, and the second charging protocol is used for fast charging on the premise of satisfying the second charging protocol, which can improve the utilization rate of the second charging protocol and ensure the safety of charging. sex.
