Description

Technical Field

[0001] The present invention relates to the field of charging management technology, and in particular to a PD fast charging management method, device and electronic equipment. Background Art

[0002] PD (Power Delivery) fast charging is a universal fast charging protocol developed by the USB standards organization. It is based on the USB TYPE-C interface and the communication is based on the CC (Channel Configuration) line of the TYPE-C protocol. As a mature fast charging protocol, some abnormal conditions will occur more or less in actual use, and when an abnormality occurs, a processing mechanism is required. The PD fast charging protocol provides a hardware reset (Hard Reset) abnormal reset mechanism, which resets the power supply end (Source) and the power consumption end (Sink) by hardware, allowing both parties to return to the reset state and re-handshake. During this hardware reset process, the charger as the power supply end will reset V BUS It will first drop from 5V to 0V, and then recover from 0V to 5V. This phenomenon is the same as unplugging the charger, so it will be mistaken for unplugging the charger, resulting in charging stop. When the machine is on, the charging icon will disappear, and then display again; and if the machine is shut down and charging at the power-consuming end, after charging stops, the upper layer will obtain that the charger is not in place, and will go through the power-off shutdown process; after shutdown, the charger is plugged in again, so the shutdown charging process will be followed, and this will be repeated, the machine will be turned on and off repeatedly, resulting in abnormal use.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] An embodiment of the present invention provides a PD fast charging management method, which is applied to electronic devices such as Figure 1 As shown, the method includes:

[0039] S11. During PD fast charging, detect whether a hardware reset is triggered;

[0040] S12, when it is detected that the hardware reset is triggered, sending a notification message to the charger driver module through the PD driver module;

[0041] S13. After the charger driving module receives the notification message, when it detects that the power supply voltage drops to 0V, the charging icon is kept displayed normally.

[0042] The PD fast charging management method provided in the embodiment of the present invention regards the event that the power supply voltage drops to 0V as a PD hardware reset event after the charger driver module receives the message from the PD driver module. Therefore, the event is ignored and not reported to the Android layer, so as to maintain the normal display of the charging icon. In this way, the charging status can be effectively managed when the PD hardware reset occurs during the PD fast charging process, avoiding repeated restart of charging after the power is turned off and the lighting of the charging icon when the power is on.

[0043] The PD fast charging management method of the present invention is described in detail below with reference to specific embodiments.

[0044] like Figure 2 As shown, the PD fast charging management method of this embodiment includes:

[0045] S21. During PD fast charging, detect whether a hardware reset is triggered.

[0046] S22: When it is detected that the hardware reset is triggered, a notification message is sent to the charger driver module through the PD driver module.

[0047] Since the hardware reset is triggered by either the power supply or the power consumption end, the hardware reset is formally initiated to V BUSThere is a time difference when the voltage actually drops from 5V to 0V. By using this time difference, if the hardware reset is initiated by the power supply end, the PD driver module at the power consumption end will receive the hardware reset interrupt first; if the hardware reset is initiated by the power consumption end, then before the hardware reset is officially initiated, the charger driver module can be informed through the extcon (USB drive status control module) notification mechanism, that is, the PD driver module knows in advance that a hardware reset is required, so the charger driver module can be informed in advance.

[0048] S23. After the charger driving module receives the notification message, when it is detected that the power supply voltage drops to 0V, the charging icon is kept displayed normally.

[0049] After receiving the message from the PD driver module, the charger driver module can prepare to turn on V BUS The event of dropping from 5V to 0V is considered to be caused by a PD hardware reset event, so V BUS The off event is ignored and not reported to the Android layer, so the charging icon will not disappear and then be displayed.

[0050] S24. After the charging icon is displayed normally for a predetermined period of time, determine whether the charger is in place. If the charger is in place, execute step S25; if the charger is not in place, execute step S26.

[0051] S25: No processing is done and the charging icon is displayed normally.

[0052] S26. Stop charging and the charging icon will no longer be displayed.

[0053] In order to prevent hardware reset and charger unplugging from happening at the same time, although the probability of this is very low, it is possible to happen. Since the entire hardware reset process will be completed within 3 seconds, when the power supply voltage is detected to drop to 0V, ignore the event and check again after 3 seconds whether the charger is in place. If the charger is in place, it is a PD hardware reset event and no processing is done, and the charging icon remains displayed normally; if the charger is not in place, it means that the charger is unplugged, then charging is stopped and the charging icon disappears. This can prevent the PD hardware reset event and charger unplugging from happening at the same time while the charging icon still exists.

[0054] The embodiment of the present invention also provides a PD fast charging management device, such as Figure 3 As shown, the device comprises:

[0055] The detection unit 11 is used to detect whether a hardware reset is triggered during PD fast charging;

[0056] The sending unit 12 is used to send a notification message to the charger driving module through the PD driving module when it is detected that the hardware reset is triggered;

[0057] The first processing unit 13 is configured to keep the charging icon displayed normally when it is detected that the power supply voltage drops to 0V after the charger driving module receives the notification message.

[0058] The PD fast charging management device provided in the embodiment of the present invention regards the event that the power supply voltage drops to 0V as a PD hardware reset event after the charger driver module receives the message from the PD driver module. Therefore, the event is ignored and not reported to the Android layer, so as to maintain the normal display of the charging icon. In this way, the charging status can be effectively managed when the PD hardware reset occurs during the PD fast charging process, avoiding repeated restart of charging after the power is turned off and the lighting of the charging icon when the power is on.

[0059] Optionally, the detection unit 13 is used to detect whether the PD driver module receives a hardware reset interrupt or a notification requesting a PD hardware reset. If the PD driver module receives a hardware reset interrupt or a notification requesting a PD hardware reset, it is detected that a hardware reset is triggered.

[0060] Furthermore, if Figure 4 As shown, the device also includes:

[0061] A judging unit 14, configured to judge whether the charger is in place after the charging icon is normally displayed for a predetermined period of time;

[0062] The second processing unit 15 is used for not performing any processing and keeping the charging icon displayed normally when the judging unit 14 detects that the charger is in place;

[0063] The third processing unit 16 is configured to stop charging and no longer display the charging icon when the determining unit 14 detects that the charger is not in place.
