Description
Technical Field
The application belongs to the technical field of communication, and particularly relates to a charging method, a charging device and a charger.
Background
At present, the terminal functions are more and more powerful, but the problem of serious power consumption is also caused; increasing battery capacity is the first solution that cell phone manufacturers think of in the case of users increasingly taking care of standby time, while fast charging schemes have emerged in the case of battery manufacturers failing to overcome battery technology. At present, the fast charging technology is a charging mode commonly adopted by mobile phone manufacturers, wherein a relatively common fast charging protocol includes a PD (Power Delivery) charging protocol, a PE (Pump Express) charging protocol, a QC (Quick Charge) charging protocol, an FCP (Fast Charge Protocol, fast charging protocol), an SCP (Super Charge Protocol, super charging protocol), a VOOC (flash charging protocol) and other charging protocols. Some of the charging protocols are universal fast charging protocols, such as PD charging protocols, and some of the charging protocols are private charging protocols customized by mobile phone manufacturers based on mobile phones produced by the mobile phone manufacturers, and the private charging protocols can enable the fast charging functions to be more suitable for the mobile phones of the mobile phones, and meanwhile, the safety is higher.
In order to be applicable to various quick charging protocols as much as possible, products such as a quick charging charger, a mobile power supply and the like support various quick charging protocols, for example, a charger supports various quick charging protocols such as QC charging protocols and PD charging protocols, a mobile phone supporting the QC charging protocols can be communicated with the charger to perform quick charging communication of the QC charging protocols, and a mobile phone supporting the PD charging protocols can be communicated with the charger to perform quick charging communication of PD charging line protocols, so that the applicability of the charger is increased; some mobile phones also support various fast charging protocols, such as a fast charging mode of a QC charging protocol and a fast charging mode of a PD charging protocol; the charger supporting the PD charging protocol is connected to conduct quick charging according to the quick charging mode of the PD charging protocol, and the charger supporting the QC charging protocol is connected to conduct quick charging according to the QC charging protocol, so that charging experience of the mobile phone is improved.
However, when the fast charging mobile phone supporting the private protocol communicates with the charger supporting multiple fast charging protocols, the private fast charging protocol is identified first, but because the communication speed of some charging protocols (such as PD charging protocol, QC charging protocol, etc.) is relatively fast, after the mobile phone is connected with the charger, the communication of the charging protocols such as PD is performed first, and the fast charging is performed according to the communication mode of the charging protocols such as PD, which obviously reduces the usability of the private charging protocol and also reduces the charging safety.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The charging method, the charging device and the charger provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a charging method according to an embodiment of the application. As shown in fig. 1, an embodiment of the present application provides a charging method, which may be applied to a charger, and the charging method may include:
step 11:
charging the powered device according to a second charging protocol if the charger and the powered device meet a handshake condition of the second charging protocol within a first preset time period after the charger and the powered device are connected, and charging the powered device according to a first charging protocol after the first preset time period if the charger and the powered device do not meet the handshake condition of the second charging protocol;
the handshake communication rate of the first charging protocol is faster than that of the second charging protocol.
In the embodiment of the application, whether the connection with the powered device is judged can be judged by: whether the Rd resistance (i.e., pull-down resistance) is detected or not is determined, for example, the Rd resistance is detected, that is, it is considered that a connection has occurred with the powered device. After the connection with the powered device occurs, since the handshake communication rate of the first charging protocol is faster than that of the second charging protocol, this means that in the prior art, the powered device will be handshake-communicated with the powered device according to the first charging protocol first, and then charged according to the first charging protocol.
It should be noted that, in the first preset duration, even if the handshake communication rate of the first charging protocol is faster, handshake communication is not completed with the powered device according to the first charging protocol and the powered device is charged according to the first charging protocol, but the first preset duration is reserved to detect whether the handshake condition of the second charging protocol is met or not, until the first preset duration is exceeded and the condition that the second charging protocol is met is not detected, handshake communication is completed with the powered device according to the first charging protocol and the powered device is charged according to the first charging protocol.
In the embodiment of the application, the charger and the powered device can support various charging protocols, including a first charging protocol and a second charging protocol, wherein the first charging protocol can be a charging protocol with a relatively fast handshake communication rate, such as a PD charging protocol, a PE charging protocol, a QC charging protocol, and the like, and the second charging protocol can be a private charging protocol, such as an FCP charging protocol, an SCP charging protocol, a VOOC charging protocol, and the like.
In the embodiment of the present application, in a first preset period of time after the charger and the powered device are connected, if the charger and the powered device meet a handshake condition of a second charging protocol, charging the powered device according to the second charging protocol includes:
delaying sending a 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;
and under the condition that the preset condition is met, if the charger and the powered device meet the handshake condition of the second charging protocol, shielding the communication signal of the first charging protocol, and charging the powered device 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 time when the charger completes handshake communication with the powered device and charges according to the first charging protocol, after the charger is connected with the powered device, the sending of the first handshake request to the powered device may be delayed (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 powered device does not receive the first handshake request within a certain period of time, and thus the powered device may be triggered to send a hard reset signal to the charger (for example, in the PD charging protocol, if the powered device cannot receive the first handshake request sent by the charger, the powered device may be triggered to send the hard reset signal, resulting in delay), and the charger will receive at least one hard reset signal sent by the powered device according to the first charging protocol; the charger and the powered device are in the handshake communication process at this time, but handshake communication is not completed, so that the powered device is not directly charged according to the first charging protocol, whether handshake conditions of the second charging protocol are met or not can be detected within a first preset duration, handshake communication is performed with the powered device according to the second charging protocol, and the powered device is charged according to the second charging protocol after handshake communication is completed; if the handshake condition meeting the second charging protocol is not detected within the first preset duration, the charger sends a first handshake request to the powered device according to the first charging protocol after the first preset duration, and then completes handshake communication with the powered device, and then charges the powered device according to the first charging protocol.
In the embodiment of the present application, the preset conditions are: the number of times of the received hard reset signal is smaller than a preset number of times, or the preset condition is that the received hard reset signal is within a second preset time after the hard reset signal is received for the first time.
In an alternative embodiment, the preset condition is that the number of times of the received hard reset signal is smaller than a preset number of times, where the preset number of times is a positive integer, for example, when the first charging protocol is a PD charging protocol, the preset number of times is set to 3, that is, when the first handshake request sent by the charger is not received, the powered device is triggered to send the hard reset signal three times in sequence, the first preset period is from the time when the connection with the powered device occurs to the time when the third hard reset signal is received, before the third hard reset signal is not received, whether the handshake condition of the second charging protocol is met or not can be detected in this period, and when the handshake condition is met, the powered device is in handshake communication with the powered device according to the second charging protocol and charges the powered device, at this time, the communication signal of the first charging protocol can be ignored or shielded, but when the handshake condition meeting the second charging protocol is still not detected after the third hard reset signal is received, in order to ensure quick response of charging, the charger can perform a quick communication with the powered device according to the first handshake request, and to ensure quick charging.
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, in the case that the first charging protocol is a PD charging protocol, although the hard reset signal triggered by the protocol is three times, in an actual scenario, a plurality of manufacturers do not set a terminal (i.e. the powered device) to trigger the hard reset signal for three times according to a standard, so in order to avoid that the third hard reset signal is not received for a long time and the power-on is not powered up, in the embodiment of the present application, a waiting time is added, that is, a second preset time period is a time period after the first hard reset signal is received, and then the second preset time period is a time period after the first hard reset signal is received, for example, until the time point when the second preset time period is reached after the first hard reset signal is received, in a practical scenario, in which time period is up to the time point when the second hard reset signal is received, and when the second charging protocol is met, and the power-on is not powered up according to the second charging protocol, and when the first power-on is not received, the first power-on protocol is still met, and when the first power-on device is still in communication with the first power-on protocol is not powered up, and the first power-on device is still in a power-on mode.
In other embodiments of the present application, optionally, in a first preset period of time after the charger and the powered device are connected, if the charger and the powered device meet a handshake condition of a second charging protocol, charging the powered device according to the second charging protocol includes:
within a first preset time period, the following operations are cycled: transmitting a first handshake request to the powered device according to the first charging protocol, and transmitting a soft reset signal and a first handshake request to the powered device when receiving a first reply signal and a power request transmitted by the powered device in response to the first handshake request;
and in the first preset duration, if the charger and the powered device meet the handshake condition of a second charging protocol, shielding the communication signal of the first charging protocol, and charging the powered device 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 time when the charger completes handshake communication with the powered device and charges according to the first charging protocol, after the charger is connected with the powered device, the following operations may be further circulated within a first preset duration: according to the prior art, under a first charging protocol (for example, PD charging protocol), the charger needs to reply to a second reply signal at this time, which indicates that the charger has received the second reply signal, and can charge the powered device according to the first charging protocol with the requested power, but in the embodiment of the application, in order to issue a time window for detecting whether the handshake condition of the second charging protocol is satisfied, the charger does not issue a second reply signal, but issues a soft reset signal and the first handshake request in sequence, because the second reply signal is not received by the powered device, communication between the charger and the powered device is established and is not completely established, and because the first handshake request is received, the powered device can respond to the first handshake request again, and send the first reply signal and the second reply signal is required, which indicates that the powered device can be charged according to the first charging protocol, and can be completely satisfied, in the first communication cycle time is not satisfied, and the communication between the powered device and the powered device is not completely satisfied, so that the communication time window of the handshake condition of the second handshake condition is satisfied, and the communication between the powered device and the powered device is not completely satisfied.
In the embodiment of the present application, if the handshake condition of the second charging protocol is not satisfied, charging the powered device according to the first charging protocol after the first preset duration includes:
and if the charger and the powered device do not meet the handshake condition of the second charging protocol within the first preset duration, after the first preset duration is exceeded, responding to the power request, and charging the powered device according to the first charging protocol.
That is, after the above operation is cycled for more than the first preset period of time, the handshake condition satisfying the second charging protocol is not detected, and the charger sends a second reply signal to the powered device after receiving the first reply signal and the power request according to the normal flow, indicating that the power request has been received, and charges the powered device with the requested power according to the first charging protocol.
In the embodiment of the present application, after the step of charging the powered device according to the first charging protocol after the first preset duration if the handshake condition of the second charging protocol is not satisfied, the method further includes:
and if the handshake condition meeting the second charging protocol is detected, stopping charging the powered device according to the first charging protocol, and switching to charging the powered device according to the second charging protocol.
Because the handshake condition meeting the second charging protocol is not detected within the first preset duration, in order to ensure timely charging of the powered device, the powered device is charged according to the first charging protocol after the first preset duration; after that, it is possible to continue to detect whether the handshake condition of the second charging protocol is satisfied, and in the case where the handshake condition of the second charging protocol is detected to be satisfied, shield communication of the first charging protocol, stop charging the powered device according to the first charging protocol, and respond to handshake communication of the second charging line protocol to charge the powered device according to the second charging protocol.
In the embodiment of the application, for the second charging protocol, whether the handshake condition of the second charging protocol is satisfied is detected, wherein the handshake condition of the second charging protocol is satisfied may be that the voltage value between D+/D-is greater than or equal to a preset voltage threshold, and correspondingly, the handshake condition of the second charging protocol is not satisfied may be that the voltage value between D+/D-is less than the preset voltage threshold; when the detection is carried out within the first preset time length, the voltage value between D+/D-can be detected for multiple times so as to ensure the accuracy of the detection result, wherein the detection time interval can be periodic or aperiodic; when the detection is performed after the first preset time period is exceeded, the detection may be performed at periodic intervals.
In the embodiment of the application, the second charging protocol is preferentially identified in the charging process, and the second charging protocol is used for rapid charging on the premise of meeting the second charging protocol, so that the utilization rate of the second charging protocol can be improved, and the charging safety is ensured.
It should be noted that, in the charging method provided by the embodiment of the present application, the execution body may be a charging device, or a control module in the charging device for executing the charging method. In the embodiment of the present application, a charging method performed by a charging device is taken as an example, and the charging device provided in the embodiment of the present application is described.
