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 also comes with; under the condition that a user pays more and more attention to the standby time, the problem of increasing the battery capacity is the first thought of a mobile phone manufacturer, and under the condition that the battery manufacturer cannot overcome the battery technology, a quick charging scheme is produced. At present, a Fast charging technology is a charging mode commonly used by mobile phone manufacturers, wherein the more commonly used Fast charging protocols include a PD (Power Delivery) charging Protocol, a PE (Pump Express) charging Protocol, a qc (quick Charge) charging Protocol, an FCP (Fast Charge Protocol), an SCP (Super Charge Protocol), a VOOC (flash charging Protocol), and other charging protocols. Some charging protocols are quick charging protocols with universality, such as PD charging protocols, and some charging protocols are proprietary charging protocols customized by mobile phone manufacturers based on mobile phones produced by the manufacturers, so that the quick charging function can be more adaptive to the mobile phones of the manufacturers, and the security is higher.
In order to be suitable for various fast charging protocols as far as possible, some products such as fast charging chargers and mobile power supplies support various fast charging protocols, for example, one charger supports various fast charging protocols such as a QC charging protocol and a PD charging protocol, a mobile phone supporting the QC charging protocol can carry out fast charging communication of the QC charging protocol when communicating with the charger, and a mobile phone supporting the PD charging protocol can carry out fast charging communication of the PD charging protocol when communicating with the charger, so that the applicability of the charger is increased; some mobile phones also support various fast charging protocols, for example, the mobile phone supports both a fast charging mode of a QC charging protocol and a fast charging mode of a PD charging protocol; the charger connected with the PD charging protocol supports rapid charging according to the rapid charging mode of the PD charging protocol, and the charger connected with the QC charging protocol supports rapid charging according to the QC charging protocol, so that the charging experience of the mobile phone is improved.
However, when a fast charging mobile phone supporting a private protocol communicates with a charger supporting multiple fast charging protocols, it is intended to preferentially identify the private fast charging protocol, but since the communication speed of some charging protocols (e.g., a PD charging protocol, a QC charging protocol, etc.) is faster, after the mobile phone is connected to the charger, the communication of the charging protocols such as PD is preferentially performed, and the fast charging is performed according to the communication mode of the charging protocols such as PD, which undoubtedly reduces the usability of the private charging protocol and also reduces the charging safety.

The charging method, the charging device and the charger provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a schematic flow chart of a charging method according to an embodiment of the present disclosure. As shown in fig. 1, an embodiment of the present application provides a charging method, which may be applied to a charger, where the charging method may include:
step 11:
within a first preset time after a charger is connected with a powered device, 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, and if the charger and the powered device do not meet the handshake condition of the second charging protocol, charging the powered device according to the first charging protocol after the first preset time;
wherein the first charging protocol has a faster handshake communication rate than the second charging protocol.
In this embodiment of the present application, it may be determined whether to connect to a powered device by: whether the Rd resistance (i.e., pull-down resistance) is detected is determined, for example, the Rd resistance is detected to be considered to be connected to the powered device. After the connection with the powered device, since the rate of the first charging protocol is faster than that of the second charging protocol, it means that in the prior art, the powered device will be handshake-communicated with the first charging protocol first, and then the powered device will be charged according to the first charging protocol, however, in this embodiment of the present invention, a time period, i.e. a first preset time period, is first set, whether the handshake condition of the second charging protocol is satisfied is detected within the first preset time period, if the handshake condition of the second charging protocol is detected within the first preset time period, the powered device will be handshake-communicated with the powered device according to the second charging protocol, and then the powered device will be charged according to the second charging protocol, and if the handshake condition of the second charging protocol is not detected within the first preset time period, the powered device will be charged according to the first charging protocol after the first preset time period, that is to say, the time that the charger accomplished the communication of shaking hands and charge to the powered device according to first charge agreement and powered device has been postponed to, under the prerequisite that hardly influences the response time of charging with being connected of powered device, whether the priority detects satisfies the condition of shaking hands of second charge agreement, can improve the rate of utilization of second charge agreement from this, and the security when improving to charge.
It should be noted that, in the first preset time period, even if the handshake communication rate of the first charging protocol is fast, the handshake communication with the powered device according to the first charging protocol is not completed and the powered device is charged according to the first charging protocol, but the first preset time period is reserved to detect whether the handshake condition of the second charging protocol is satisfied, and until the first preset time period is exceeded and the second charging protocol is not detected to be satisfied, the handshake communication with the powered device according to the first charging protocol is completed and the powered device is charged 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 set higher handshake communication rate, such as a PD charging protocol, a PE charging protocol, a QC charging protocol, and the second charging protocol may be a private charging protocol, such as an FCP charging protocol, an SCP charging protocol, a VOOC charging protocol, and the private charging protocol is provided with a protection measure of a terminal produced by a mobile phone manufacturer, so that the security is stronger, and therefore, the charging security can be ensured by preferentially using the second charging protocol to charge the powered device.
In this embodiment of this application, in the first preset duration after charger and powered device take place to be connected, if the charger with powered device satisfies the condition of shaking hands of second protocol of charging, then it is right according to the second protocol of charging the powered device charges, include:
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 shielding the communication signal of the first charging protocol and charging the powered device according to the second charging protocol if the charger and the powered device meet the handshake condition of the second charging protocol under the condition of meeting the preset condition.
In the embodiment of the application, because the handshake communication rate of the first charging protocol is faster than that of the second charging protocol, therefore, in order to postpone the moment when the charger completes handshake communication with the powered device according to the first charging protocol and performs charging, after the connection with the powered device, the sending of the first handshake request to the powered device may be postponed (as in the prior art the first handshake request is sent to the powered device according to the first charging protocol immediately after the connection with the powered device), because the powered device does not receive the first handshake request within a certain period of time, the powered device may be triggered to send a hard reset signal to the charger (for example, in a PD charging protocol, if the powered device does not receive the first handshake request sent by the charger, the powered device may be triggered to send the hard reset signal, which causes a delay), and thus the charger will receive at least one hard reset signal sent by the powered device according to the first charging protocol; at this time, the charger and the powered device are in the process of handshake communication, but the handshake communication is not completed, so that the powered device cannot be directly charged according to the first charging protocol, and therefore, whether the handshake condition of the second charging protocol is met or not can be detected within the first preset time, the powered device is handshake communicated according to the second charging protocol and is charged according to the second charging protocol after the handshake communication is completed; if the handshake condition meeting the second charging protocol is not detected within the first preset time, after the first preset time, the charger sends a first handshake request to the powered device according to the first charging protocol, 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 received hard reset signal frequency is less than a preset frequency, or the preset condition is that the hard reset signal is within a second preset time after being received for the first time.
In an optional embodiment, the preset condition is that the number of times the hard reset signal is received is less than a preset number of times, where the preset number of times is a positive integer, for example, in a case that the first charging protocol is a PD charging protocol, the preset number of times is set to 3, that is, in a case that a first handshake request sent by a charger is not received, the powered device is triggered to send three hard reset signals in sequence, a first preset duration is a time when the powered device is connected, and until a 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 satisfied may be detected in the duration, and when the handshake condition is satisfied, the powered device is communicated with and charged according to the second charging protocol, at this time, a communication signal of the first charging protocol may be ignored or shielded, however, if the handshake condition meeting the second charging protocol is not detected after the third hard reset signal is received, in order to ensure a fast response of charging, the charger sends a first handshake request to the powered device according to the first charging protocol, completes handshake communication with the powered device, and charges the powered device according to the first charging protocol, thereby ensuring that the powered device can still be charged more quickly.
In another alternative embodiment, the ending time may be within a second preset time period after the hard reset signal is received for the first time, for example, in a case that the first charging protocol is a PD charging protocol, although the triggered hard reset signal specified by the protocol is three times, in an actual scenario, many manufacturers do not set the terminal (i.e., the powered device) to trigger the hard reset signal three times according to a standard, so as to avoid that the third hard reset signal is not received for a long time and the powered device cannot be powered on, in this embodiment of the present application, a waiting time, that is, a second preset time period, is added, that is, after the first hard reset signal is received, a time of the second preset time period again, in this case, the first preset time period is a time when the powered device is connected, and a time of the second preset time period is reached after the first hard reset signal is received, during the period, whether the handshake condition of the second charging protocol is met or not can be detected, when the handshake condition is met, the communication with the powered device is performed according to the second charging protocol, and the powered device is charged, at this time, the communication signal of the first charging protocol can be ignored or shielded, if the subsequent hard reset signal is not received even when the second preset time length is exceeded, the first handshake request is sent to the powered device according to the first charging protocol, the handshake communication is established with the powered 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 is connected to the powered device, if the charger and the powered device satisfy a handshake condition of a second charging protocol, the powered device is charged according to the second charging protocol, including:
cycling the following operations within a first preset time period: transmitting a first handshake request to the powered device according to the first charging protocol, and transmitting a soft reset signal and the 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 shielding the communication signal of the first charging protocol if the charger and the powered device meet the handshake condition of a second charging protocol within the first preset time, and charging the powered device according to the second charging protocol.
In this embodiment of the present application, since the rate of the first charging protocol is faster than that of the second charging protocol, in order to postpone the time when the charger completes the handshake communication with the powered device according to the first charging protocol and performs charging, after the charger is connected to the powered device, the following operations may be cycled for a first preset time period: if a first handshake request is sent to the powered device according to the first charging protocol, the powered device will send a first reply signal and a power request in response to the first handshake request, where 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 a power stage required by the powered device itself, according to the prior art, under the first charging protocol (e.g. PD charging protocol), the charger needs to reply with a second reply signal at this time, which indicates that the charger has received the power request, and can charge the powered device with the requested power according to the first charging protocol, but in this embodiment, in order to try to detect whether a time window of handshake conditions 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, and if the first handshake request is received, the powered device sends a first reply signal and a power request to the charger in response to the first handshake request, and the cycle is repeated, so that the handshake communication process between the charger and the powered device is always cycled for a certain time in the two steps, namely for a first preset time period, and during the time period, whether the handshake condition of the second charging protocol is met can be detected, and if the handshake communication process is met, the powered device is handshake communicated with the powered device according to the second charging protocol and is charged, and at this time, the communication signal of the first charging protocol can be ignored or shielded.
In this 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 time period includes:
and if the charger and the powered device do not meet the handshake condition of the second charging protocol within the first preset time, responding to the power request after the first preset time is exceeded, 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 time period, and the handshake condition meeting the second charging protocol is still not detected, the charger will send the second reply signal to the powered device after receiving the first reply signal and the power request according to the normal procedure, which indicates that the power request has been received, and charge the powered device with the requested power according to the first charging protocol.
In this embodiment of the application, if the handshake condition of the second charging protocol is not satisfied, after the step of charging the powered device according to the first charging protocol after the first preset time period, 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.
As the handshake condition meeting the second charging protocol is not detected within the first preset time, in order to ensure that the powered device is charged in time, the powered device is charged according to the first charging protocol after the first preset time; after that, it may be continued to detect whether the handshake condition of the second charging protocol is satisfied, and in a case where it is detected that the handshake condition of the second charging protocol is satisfied, the communication of the first charging protocol is masked, the charging of the powered device according to the first charging protocol is stopped, and the powered device is charged according to the second charging protocol in response to the handshake communication of the second charging line protocol.
In the embodiment of the application, for the second charging protocol, whether the handshake condition of the second charging protocol is met is detected, the handshake condition meeting the second charging protocol may be that the voltage value between D +/D-is greater than or equal to the preset voltage threshold, and correspondingly, the handshake condition not meeting the second charging protocol 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 to ensure the accuracy of the detection result, and the detection time interval can be periodic or aperiodic; when the detection is performed after the first preset time length is exceeded, optionally, the detection may be performed periodically at certain time intervals.
In the embodiment of the application, in the charging process, the second charging protocol is preferentially identified, and the second charging protocol is used for quick 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.
In the charging method provided in the embodiment of the present application, the execution main body may be a charging device, or a control module in the charging device for executing the charging method.
