Description

Technical Field

[0001] The present disclosure relates to the field of charging technology, and particularly to a charging control method, a power supply control method, a device, a medium, and an electronic device. Background Art

[0002] In the related art, when a device to be charged needs to be charged, a charger is connected to the device to be charged through a connector to charge the device to be charged. During the charging process, if there is a short-circuit foreign object at the port of the connector, it will induce the port temperature to rise. If it is detected that the temperature of the connector port is overheated (for example, the temperature exceeds 70 degrees Celsius), the anti-burning MOS switch in the device to be charged will be turned off, and the hardware path between the charger and the device to be charged will be cut off. At this time, the charger will automatically enter the overcurrent protection state, and the charger will enter the hiccup state. In this hiccup state, the temperature of the connector port will not continue to rise, thus playing a role in protecting the port. However, this anti-burning method will increase the hardware cost of the device to be charged. Summary of the Invention

[0024] According to a second aspect of the embodiments of the present disclosure, a power supply control method is provided, including: receiving a shutdown instruction sent by a device to be charged, where the shutdown instruction is used to instruct a charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is an upper limit voltage that will not cause the port of the connector connecting the charger and the device to be charged to burn; based on the shutdown instruction, reducing the output voltage of the charger to be lower than the first voltage.

[0025] According to a third aspect of the embodiments of the present disclosure, a charging control device is provided, including: an acquisition module, configured to acquire the port temperature of a connector connecting a charger and a device to be charged; a sending module, configured to send a shutdown instruction to the charger if the port temperature is higher than a first temperature, where the first temperature is a lower limit temperature that can cause the port of the connector to burn out, and the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is an upper limit voltage that will not cause the port of the connector to burn out.

[0026] According to a fourth aspect of the embodiments of the present disclosure, a power supply control device is provided, including: a receiving module, configured to receive a shutdown instruction sent by a device to be charged, where the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is an upper limit voltage that will not cause the port of a connector connecting the charger and the device to be charged to burn out; a shutdown module, configured to, based on the shutdown instruction, reduce the output voltage of the charger to be lower than the first voltage.

The first voltage is the upper limit voltage that will not cause the port of the connector to burn out. In this way, on the one hand, it is not necessary to set an anti-burning MOS switch on the side of the device being charged to prevent the connector port from burning out. Therefore, the anti-burning MOS switch on the hardware side of the device being charged can be removed, reducing the hardware cost of the device being charged. On the other hand, when the port temperature of the connector is higher than the first temperature, by sending a shutdown instruction to the charger, the output voltage of the charger can be reduced to be lower than the upper limit voltage that causes the connector port to burn out, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0041] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] It should be noted that all actions of obtaining signals, information, or data in the present disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and with the authorization given by the owner of the corresponding device.

[0043] Figure 1 is a flowchart of a charging control method shown according to an exemplary embodiment. The charging control method can be applied to a device to be charged, such as a mobile phone, a tablet computer, etc. The charging control method can also be applied to various fast charging scenarios, for example, a fast charging scenario based on the Power Delivery (PD) protocol. As Figure 1 shown, the charging control method according to an embodiment of the present disclosure includes the following steps S11 to S12.

[0044] In step S11, obtain the port temperature of the connector connecting the charger and the device to be charged.

[0045] The port temperature of the connector can be detected by various temperature sensors, such as a Negative Temperature Coefficient (NTC) resistor, etc.

[0046] In step S12, if the port temperature is higher than a first temperature, send a shutdown instruction to the charger, where the first temperature is the lower limit temperature that can cause the port of the connector to burn out, and the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is the upper limit voltage that will not cause the port of the connector to burn out.

[0047] For example, the first temperature can be 70 degrees Celsius or other preset temperatures. The first voltage can be 2.5V, 0V, or other values. In addition, there are many reasons why the port temperature of the connector is higher than the first temperature. For example, a serious short circuit occurs at the port of the connector, and the serious short circuit may be caused by foreign objects or corrosion at the port.

[0048] By adopting the above technical solution, when the port temperature of the connector is higher than the first temperature, a shutdown instruction is sent to the charger, where the first temperature is the lower limit temperature that can cause the port of the connector to burn out, and the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than the first voltage, and the first voltage is the upper limit voltage that will not cause the port of the connector to burn out. In this way, on the one hand, it is not necessary to set a burn-proof MOS switch on the side of the device to be charged to prevent the connector port from burning out, so the hardware burn-proof MOS switch can be removed on the side of the device to be charged, reducing the hardware cost of the device to be charged. On the other hand, when the port temperature of the connector is higher than the first temperature, by sending a shutdown instruction to the charger, the output voltage of the charger can be reduced to be lower than the upper limit voltage that causes the connector port to burn out, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0049] In some embodiments, the charging control method according to the embodiments of the present disclosure may further include: counting the number of times the shutdown instruction is sent; determining the sending period of the shutdown instruction based on the count. For example, if the count is less than or equal to the first count value, it is determined that the sending period of the shutdown instruction is the first period; if the count is greater than the first count value, it is determined that the sending period of the shutdown instruction is the second period, where the second period is greater than the first period. The first count value, the first period, and the second period can all be set according to the actual application scenario. For example, the first count value can be set to 3, the first period can be set to 100 ms, the second period can be set to 30 s, and so on.

[0050] By adopting the above technical solution, on the one hand, the shutdown instruction can be sent to the charger periodically. On the other hand, at the initial stage of sending the shutdown instruction, the shutdown instruction can be sent to the charger at a high frequency to ensure that the charger can receive the shutdown instruction, avoiding the output voltage of the charger not being reduced to be lower than the first voltage due to abnormal sending of the shutdown instruction, and then being able to suppress the temperature rise of the connector port as soon as possible and effectively and prevent the connector port from burning out. In the middle and late stages of sending the shutdown instruction, since the shutdown instruction has been successfully sent to the charger, the sending of the shutdown instruction is no longer urgent. At this time, by extending the sending period of the shutdown instruction, energy can be effectively saved.

[0051] In some embodiments, in step S12, if the port temperature is higher than the first temperature, sending the shutdown instruction to the charger includes:

[0052] If the port temperature is higher than the first temperature, obtain the output voltage of the charger;

[0053] If the output voltage of the charger is higher than the first voltage, send the shutdown instruction to the charger.

[0054] That is, whether to send the shutdown instruction is related not only to the port temperature but also to the output voltage of the charger. When the output voltage of the charger is lower than the first voltage, there is no need to send the shutdown instruction to the charger.

[0055] By adopting the above technical solution, the shutdown instruction will be sent to the charger when the port temperature is higher than the first temperature and the output voltage of the charger is higher than the first voltage, and the shutdown instruction will not be sent to the charger in other cases, which can ensure the effective charging of the device being charged.

[0056] In some embodiments, the charging control method according to the embodiments of the present disclosure may further include: identifying the charging type; and determining the sending manner of the shutdown instruction based on the identified charging type. That is, different charging types will adopt different ways to send the shutdown instruction.

[0057] For example, if the identified charging type is Programmable Power Supply (PPS), it is determined to send the shutdown instruction in the form of an Unstructed Vendor Defined Message (UVDM). With the help of UVDM, users can customize various types of instructions. In addition, for the scenario where the connector port is not corroded or damaged, the device being charged can correctly identify the charging type, for example, it can correctly identify that the PPS charging type is currently used to charge the device being charged.

[0058] In addition, when the identified charging type is the PPS charging type, the shutdown instruction can be first sent to the charger in the form of UVDM, and after sending the shutdown instruction, the output voltage of the charger is obtained. If the output voltage of the charger does not drop below the first voltage, the shutdown instruction is continuously sent to the charger again in the form of UVDM. If the output voltage of the charger still does not drop below the first voltage after continuously sending the shutdown instruction to the charger N times (for example, 3 times) in the form of UVDM, the shutdown instruction can be sent to the charger by converting to the differential data transmission method. In this way, it is ensured that the shutdown instruction can be successfully sent to the charger. The differential data transmission method will be described in detail below.

[0059] For another example, if the identified charging type is a charging type other than the programmable power supply protocol, it is determined to send the shutdown instruction in a differential data transmission manner. For scenarios where the connector port is corroded or has foreign objects, the device being charged cannot correctly identify the PPS charging type, and the shutdown instruction is sent in a differential data transmission manner. The differential data transmission method can be to transmit the shutdown instruction through the Data+ pin and the Data- pin of the connector port. For example, N (such as 5) consecutive square wave signals can be generated on the Data+ pin and the Data- pin as the shutdown instruction.

[0060] By adopting the above technical solution, it is possible to send the shutdown instruction in different ways under different charging types, ensuring that the shutdown instruction can be successfully sent to the charger, thereby effectively suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0061] Figure 2 It is a flowchart of another charging control method shown according to an exemplary embodiment.

[0062] As Figure 2 shown, first, obtain the port temperature of the connector connecting the charger and the device being charged.

[0063] Then, determine whether the port temperature of the connector is higher than a first temperature, where the first temperature is the lower limit temperature that can cause the port of the connector to burn out.

[0064] Then, if the port temperature of the connector is higher than the first temperature, determine whether the charging type is the PPS charging type.

[0065] Then, if the charging type is the PPS charging type, determine whether the output voltage of the charger is higher than a first voltage, where the first voltage is the upper limit voltage that will not cause the port of the connector to burn out. If the output voltage of the charger is higher than the first voltage, send the shutdown instruction to the charger in the UVDM manner and count the number of times the shutdown instruction is sent. Then, determine whether the count is less than a first count value. If the count is less than the first count value, determine the transmission period of the shutdown instruction as a first period (such as 200 ms). If the count is greater than the first count value, determine the transmission period of the shutdown instruction as a second period (such as 30 s), where the second period is greater than the first period. Then, determine whether the port temperature is lower than a second temperature (such as 60 degrees Celsius), where the second temperature is the upper limit temperature at which normal charging can be restored. If the port temperature is lower than the second temperature, the output voltage of the charger returns to normal and the device being charged resumes normal charging. If the port temperature is higher than the second temperature, return to the step of determining whether the output voltage of the charger is higher than the first voltage, or it is also possible to return to the step of determining whether the charging type is the PPS charging type.

[0066] In addition, if the charging type is not the PPS charging type, determine whether the output voltage of the charger is higher than a first voltage, where the first voltage is the upper limit voltage that will not cause the port of the connector to burn out. If the output voltage of the charger is higher than the first voltage, send a shutdown instruction to the charger in the form of differential data transmission and count the number of times the shutdown instruction is sent. Then, determine whether the count is less than a first count value. If the count is less than the first count value, determine the transmission period of the shutdown instruction as a third period (e.g., 100 ms). If the count is greater than the first count value, determine the transmission period of the shutdown instruction as a fourth period (e.g., 30 s), where the fourth period is greater than the third period. In addition, the first period may be greater than, equal to, or less than the third period, and the second period may be greater than, equal to, or less than the fourth period. Then, determine whether the port temperature is lower than a second temperature (e.g., 60 degrees Celsius), where the second temperature is the upper limit temperature at which normal charging can be restored. If the port temperature is lower than the second temperature, the output voltage of the charger returns to normal and the device being charged resumes normal charging. If the port temperature is higher than the second temperature, return to the step of determining whether the output voltage of the charger is higher than the first voltage, or alternatively, return to the step of determining whether the charging type is the PPS charging type.

[0067] Figure 2 The specific implementation manners of the operations performed in each step of the charging control method shown have been described in detail in the foregoing text and will not be elaborated herein.

[0068] By adopting the above technical solution, on the one hand, it is not necessary to set a burn-proof MOS switch on the device being charged to prevent the connector port from burning out. Therefore, the burn-proof MOS switch on the hardware side of the device being charged can be removed, reducing the hardware cost of the device being charged. On the other hand, when the port temperature of the connector is higher than the first temperature, the output voltage of the charger can be reduced to be lower than the upper limit voltage that causes the connector port to burn out by sending a shutdown instruction to the charger, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0069] Figure 3 is a flowchart of a power supply control method according to an embodiment of the present disclosure. The power supply control method can be applied to a charger. The power supply control method can also be applied to various fast charging scenarios, for example, a fast charging scenario based on the PD protocol. As Figure 3 shown, the power supply control method according to an embodiment of the present disclosure may include the following steps S31 to S32.

[0070] In step S31, a shutdown instruction sent by the device to be charged is received, where the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is the upper limit voltage that will not cause the port of the connector connecting the charger and the device to be charged to burn out.

[0071] Regarding the shutdown instruction, it has been described in detail above and will not be elaborated here.

[0072] In step S32, based on the shutdown instruction, the output voltage of the charger is reduced to be lower than the first voltage.

[0073] In addition, after the charger reduces the output voltage of the charger to be lower than the first voltage, the charger can start timing. If the charger does not receive the shutdown instruction from the device to be charged after the timing reaches a preset duration (for example, 1 minute), the charger can restore its output voltage to the normal charging voltage.

[0074] By adopting the above technical solution, since it is possible to receive the shutdown instruction sent by the device to be charged and, based on the shutdown instruction, reduce the output voltage of the charger to be lower than the first voltage, where the first voltage is the upper limit voltage that will not cause the port of the connector connecting the charger and the device to be charged to burn out. In this way, on the one hand, it is not necessary to set a burn - proof MOS switch on the side of the device to be charged to prevent the connector port from burning out, so the hardware burn - proof MOS switch can be removed on the side of the device to be charged, reducing the hardware cost of the device to be charged. On the other hand, it is possible to make the output voltage of the charger drop below the upper limit voltage that causes the connector port to burn out based on the shutdown instruction, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0075] Figure 4 It is a schematic block diagram of a charging control device according to an embodiment of the present disclosure. This charging control device can be applied to devices to be charged, such as mobile phones, tablet computers, etc. This charging control device can also be applied to various fast - charging scenarios, for example, fast - charging scenarios based on the Power Delivery (PD) protocol.

[0076] As Figure 4 shown, the charging control device according to an embodiment of the present disclosure includes: an acquisition module 41, configured to acquire the temperature of the port of the connector connecting the charger and the device to be charged; a sending module 42, configured to send a shutdown instruction to the charger if the port temperature is higher than a first temperature, where the first temperature is the lower limit temperature that can cause the port of the connector to burn out, and the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than a first voltage, and the first voltage is the upper limit voltage that will not cause the port of the connector to burn out.

[0077] By adopting the above technical solution, when the port temperature of the connector is higher than the first temperature, a shutdown instruction will be sent to the charger. Herein, the first temperature is the lower limit temperature that can cause the port of the connector to burn out, and the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger to be lower than the first voltage. The first voltage is the upper limit voltage that will not cause the port of the connector to burn out. In this way, on the one hand, it is not necessary to set an anti-burning MOS switch on the side of the device being charged to prevent the connector port from burning out. Therefore, the anti-burning MOS switch on the hardware side of the device being charged can be removed, reducing the hardware cost of the device being charged. On the other hand, when the port temperature of the connector is higher than the first temperature, by sending a shutdown instruction to the charger, the output voltage of the charger can be reduced to be lower than the upper limit voltage that causes the connector port to burn out, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

[0078] Optionally, the charging control device further includes:

[0079] A counting module for counting the number of times the shutdown instruction is sent;

[0081] Optionally, the first determination module determines the sending period of the shutdown instruction based on the count, including:

[0082] If the count is less than or equal to the first count value, determine that the sending period of the shutdown instruction is the first period;

[0083] If the count is greater than the first count value, determine that the sending period of the shutdown instruction is the second period, where the second period is greater than the first period.

[0084] Optionally, the step of if the port temperature is higher than the first temperature, then sending a shutdown instruction to the charger includes:

[0085] If the port temperature is higher than the first temperature, obtain the output voltage of the charger;

[0086] If the output voltage of the charger is higher than the first voltage, then send the shutdown instruction to the charger.

[0087] Optionally, the charging control device further includes:

[0088] An identification module for identifying the charging type;

[0089] A second determination module for determining the sending mode of the shutdown instruction based on the identified charging type.

[0090] Optionally, the second determination module determines the sending manner of the shutdown instruction based on the recognized charging type, including:

[0091] If the recognized charging type is a programmable power supply protocol, it is determined to send the shutdown instruction in the form of an unstructured vendor - defined message.

[0092] Optionally, the second determination module is further configured to:

[0093] After sending the shutdown instruction in the form of the unstructured vendor - defined message, obtain the output voltage of the charger;

[0094] If the output voltage of the charger does not drop below the first voltage, it is determined to continue sending the shutdown instruction in the form of differential data transmission.

[0095] Optionally, the second determination module determines the sending manner of the shutdown instruction based on the recognized charging type, including:

[0096] If the recognized charging type is a charging type other than the programmable power supply protocol, it is determined to send the shutdown instruction in the form of differential data transmission.

[0097] The specific implementation manners of the operations performed by each module in the charging control device according to the embodiments of the present disclosure have been described in detail in the related charging control method, and will not be elaborated here.

[0098] Figure 5 FIG. is a schematic block diagram of a power supply control device according to an embodiment of the present disclosure. The power supply control device can be applied to a charger. The power supply control device can also be applied to various fast - charging scenarios, for example, a fast - charging scenario based on the PD protocol.

[0099] As Figure 5 shown, the power supply control device according to the embodiment of the present disclosure includes: a receiving module 51, configured to receive a shutdown instruction sent by a device to be charged, where the shutdown instruction is used to instruct the charger to reduce the output voltage of the charger below a first voltage, and the first voltage is an upper limit voltage that will not cause the port of the connector connecting the charger and the device to be charged to burn out; a shutdown module 52, configured to reduce the output voltage of the charger below the first voltage based on the shutdown instruction.

[0100] By adopting the above technical solution, since the charger can receive the shutdown instruction sent by the device to be charged and, based on the shutdown instruction, reduce the output voltage of the charger to be lower than the first voltage, where the first voltage is the upper limit voltage that will not cause the port of the connector connecting the charger and the device to be charged to burn out. In this way, on the one hand, it is not necessary to set an anti-burning MOS switch on the device to be charged to prevent the connector port from burning out. Therefore, the anti-burning MOS switch can be removed from the hardware on the device to be charged, reducing the hardware cost of the device to be charged. On the other hand, based on the shutdown instruction, the output voltage of the charger can be reduced to be lower than the upper limit voltage that causes the connector port to burn out, thereby effectively achieving the purpose of suppressing the temperature rise of the connector port and preventing the connector port from burning out.

For example, the device 800 can be a mobile phone, a computer, a digital broadcast terminal, a messaging device, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, etc.
