Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be noted that, all actions for acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
Fig. 1 is an application scenario diagram of a charging method according to an exemplary embodiment of the present disclosure. The adapter 110 may establish a communication connection with the terminal device 120 to enable information interaction, signaling control, etc. between the two. The terminal device 120 may be any terminal device such as a mobile phone, a tablet computer, and an intelligent wearable device. The adapter 110 and the terminal device 120 may be communicatively coupled to enable transmission of signals and data between the adapter 110 and the terminal device 120 and to enable charging of the terminal device 120 via the adapter 110.
Fig. 2 is a flowchart of a charging method provided in an exemplary embodiment of the present disclosure. The method may be applied to the terminal device 120 as shown in fig. 1, and the method may be applied to a controller in the terminal device 120, for example. As shown in fig. 2, the method may include S201 to S202.
S201, it is determined whether the adapter has a charging capability to supply the target charging power.
Wherein the target charging power is greater than a default charging power provided by the adapter by default.
Illustratively, the default charging power provided by the adapter by default may be preset before the adapter leaves the factory, for example, may be set to 120W. And the target charging power is the charging power that the terminal device supports and is currently required, for example, the target charging power is 200W. With the continuous updating of the terminal device, the charging power that the terminal device can support is also increasing, however, the adapter connected to the terminal device does not necessarily have a charging capability to provide the target charging power. For example, the target charging power of the terminal device has reached 200W, and the maximum current that the adapter connected to the adapter can provide is smaller than the target current corresponding to the target charging power, and in the case that the voltage is certain, the output power of the adapter is smaller than the target charging power of the terminal device, it may be determined that the adapter does not have the charging capability of providing the target charging power; if the maximum current that the adapter can provide is greater than the target current corresponding to the target charging power, and the output power of the adapter can reach the target charging power of the terminal equipment under the condition of a certain voltage, the adapter can be determined to have the charging capability of providing the target charging power.
S202, in response to determining that the adapter has the charging capability for providing the target charging power, a first demand current instruction for indicating the current demand current with a first bit number is sent to the adapter, so that the adapter charges the terminal device according to the first demand current instruction.
The first bit number is larger than the second bit number indicating the current required current to be used by default, and the maximum current indicated by the second bit number is smaller than the current required current indicated by the first required current instruction.
Illustratively, the second number of bits indicating the current demand current mode usage typically includes 7 bits, e.g., 000 0001, indicating a current of 200mA. The maximum current that the second number of bits can indicate may be 6.35A. In the case where it is determined that the adapter has a charging capability to provide the target charging power, the allowable value of the current demand current is made larger than the maximum current that can be indicated by the second number of bits used by default by expanding the bits used to indicate the current demand current, for example, expanding 1 bit so that the first number of bits is 1 bit more than the second number of bits. For example, the second number of bits includes 7 bits, the maximum current that can be indicated may be 6.35A, and the first number of bits includes 8 bits, the maximum current that can be indicated may be 12.75A. The terminal device may send a first current demand instruction to the adapter in a form of a broadcast packet in a PD protocol (Power Delivery protocol).
The maximum current that the second number of bits can indicate is less than the current demand current indicated by the first demand current command, i.e., the current demand current indicated by the first number of bits is greater than the maximum current that the second number of bits can indicate (e.g., 6.35A). If it is determined that the adapter has a charging capability to provide the target charging power and the current demand current of the terminal device is 10A, the terminal device may send a first demand current instruction for indicating the current demand current (i.e., 10A) with a first number of bits to the adapter, so that the adapter charges the terminal device according to the first demand current instruction. Thus, under the condition that the voltage is unchanged, the charging power can be improved and the charging time can be shortened through the increase of the current.
Fig. 3 is a flowchart of a charging method provided in an exemplary embodiment of the present disclosure. The method may be applied to the adapter 110 as shown in fig. 3, and the method may be applied to a controller in the adapter 110, for example. As shown in fig. 3, the method may include S301 to S304.
S301, receiving a charging capability identification instruction sent by the terminal equipment.
The charging capability identification instruction indicates a target charging current corresponding to a target charging power, and the target charging power is larger than a default charging power provided by the adapter by default.
For example, if the target charging power is 200W and the charging voltage is 20V, the corresponding target charging current is 10A, and the charging capability identification instruction may indicate that the target charging current is 10A. The adapter may determine whether the adapter has a charging capability that provides the target charging power based on the received charging capability identification instruction.
S302, in response to determining that the target charging current is not greater than the maximum current that the adapter can provide, a first charging capability confirmation instruction is sent to the terminal device.
Wherein the first charge capacity confirmation instruction characterizes the target charge current as not being greater than a maximum current that the adapter is capable of providing.
As an example, the maximum current that the adapter can provide may be preset, for example, may be set to 12.75A, and if the target charging current is 10A, that is, the target charging current is not greater than the maximum current that the adapter can provide, it may be determined that the adapter has a charging capability to provide the target charging power, and a first charging capability confirmation instruction is sent to the terminal device so that the terminal device knows whether the adapter has the charging capability to provide the target charging power.
S303, receiving a first demand current instruction sent by the terminal equipment.
The first demand current instruction is used for indicating the current demand current of the terminal equipment by using a first bit number, the first bit number is larger than a second bit number used for indicating the current demand current by default, and the maximum current indicated by the second bit number is smaller than the current demand current indicated by the first demand current instruction.
S304, charging the terminal equipment according to the first demand current instruction.
The first demand current command is used to indicate the current demand current of the terminal device with a first bit number, and if the current demand current is 10A, the adapter can control the current of the output 10A according to the first demand current command so as to charge the terminal device.
In the case that it is determined that the adapter has a charging capability to provide the target charging power, the adapter may be caused to charge the terminal device according to the first demand current command by a first demand current command indicating a current demand current with a first number of bits that is greater than a second number of bits that indicates a current demand current to be used by default, the second number of bits being capable of indicating a maximum current that is less than the current demand current indicated by the first demand current command. In this way, when the terminal device has a charging requirement for a higher target charging power and the adapter has a charging capability for providing the target charging power, the higher current demand current is indicated by the extended bit number, so that the adapter can charge the terminal device according to the current demand current indicated by the extended bit number, thereby improving the charging power, shortening the charging time, and improving the use experience of the user. In addition, fast charging can be achieved by modifying the protocol (i.e., indicating a higher current demand current by an extended number of bits), and for existing adapters that support less charging power, high power fast charging can be achieved without hardware-related modifications to the adapter as long as the adapter has a charging capability that provides the target charging power.
Fig. 4 shows a signaling interaction diagram between a terminal device and an adapter when implementing the charging method provided by the present disclosure, and the signaling interaction procedure between the terminal device and the adapter may be more clearly shown by fig. 4. As shown in fig. 4:
in step S401, the terminal device transmits a charging capability identification instruction to the adapter.
The charging capability identification instruction indicates a target charging current corresponding to a target charging power, and the target charging power is larger than a default charging power provided by the adapter by default.
In step S402, the adapter determines whether there is a charging capability to provide the target charging power in response to the charging capability identification instruction.
For example, the adapter may determine whether itself has a charging capability to provide the target charging power by comparing the maximum current that itself can provide with the target charging current. Wherein, in the case where the target charging current is not greater than the maximum current that the adapter can provide, it is determined that the adapter has a charging capability to provide the target charging power, step S403 is performed. Otherwise, in the case where the target charging current is greater than the maximum current that the adapter can provide, it is determined that the adapter does not have the charging capability to provide the target charging power, step S404 is performed.
In step S403, in response to determining that the target charging current is not greater than the maximum current that the adapter can provide, the adapter transmits a first charging capability confirmation instruction to the terminal device.
Wherein the first charging capability confirmation instruction characterizes that the target charging current is not greater than the maximum current that the adapter can provide, i.e. that the adapter has a charging capability that provides the target charging power.
In step S404, in response to determining that the target charging current is greater than the maximum current that the adapter can provide, the adapter sends a second charging capability confirmation instruction to the terminal device.
Wherein the second charging capability confirmation instruction characterizes that the target charging current is greater than the maximum current that the adapter is capable of providing, i.e. characterizes that the adapter does not have a charging capability to provide the target charging power.
In step S405, in response to receiving the first charging capability confirmation instruction sent by the adapter, the terminal device determines that the adapter has a charging capability that provides the target charging power. After that, step S407 is performed.
In step S406, in response to receiving the second charging capability confirmation instruction sent by the adapter, the terminal device determines that the adapter does not have the charging capability to provide the target charging power. After that, step S409 is performed.
In step S407, in response to determining that the adapter has a charging capability to provide the target charging power, the terminal device transmits a first demand current instruction for indicating the present demand current in a first number of bits to the adapter.
The first bit number is larger than the second bit number indicating the current required current to be used by default, and the maximum current indicated by the second bit number is smaller than the current required current indicated by the first required current instruction.
In step S408, the adapter charges the terminal device according to the first demand current instruction.
In step S409, in response to determining that the adapter does not have the charging capability to provide the target charging power, the terminal device transmits a second demand current instruction for indicating the present demand current in a second number of bits to the adapter.
Wherein the present demand current indicated by the second demand current command is not greater than the maximum current that the second number of bits can indicate.
For example, if the target charging power is 200W, the corresponding target charging current is 10A, and the maximum current that the adapter can provide is 6.35A, the adapter does not have the charging capability to provide the target charging power, and cannot output a current of 10A. At this time, in order to adapt the terminal device to the power of the adapter, the terminal device may send a second demand current instruction for indicating the current demand current by a second number of bits to the adapter so that the adapter charges the terminal device according to the second demand current instruction, for example, the terminal device may send a second demand current instruction for indicating the current demand current (e.g., 6A) by the second number of bits to the adapter so that the adapter outputs the current of 6A to charge the terminal device.
Further, the second charging capability confirmation instruction sent by the adapter may further include the maximum power that the adapter can provide, or the maximum current that the adapter can provide. Therefore, the terminal equipment can adjust the working state of the internal charging pump according to the received maximum power or maximum current, so that the second demand current instruction which is determined and sent by the terminal equipment is more accurate.
Illustratively, to enable a terminal device to achieve fast charging, multiple charge pumps may be provided inside the terminal device, e.g., 3 charge pumps may support 200W charging, 2 charge pumps may support 120W charging, and 1 charge pump may support 67W charging. If the target charging power is 200W and the adapter does not have the charging capability for providing the target charging power, the number of charging pumps started in the terminal device can be determined according to the maximum power or the maximum current which can be provided by the adapter and is carried in the returned second charging capability confirmation instruction, so that charging is achieved. For example, if the maximum power that the adapter carried in the second charging capability confirmation instruction can provide is 67W, the terminal device can be charged by starting 1 charging pump.
In step S410, the terminal device is charged according to the second demand current instruction.
In this way, in the case where the adapter does not have a charging capability to supply the target charging power, the terminal device can adapt to the adapter to realize charging with a smaller charging power.
By means of the charging mode, when the terminal equipment has a charging requirement for a higher target charging power and the adapter has a charging capability for providing the target charging power, the higher current required current is indicated through the expanded bit number, and the adapter can charge the terminal equipment according to the current required current indicated by the expanded bit number, so that the charging power is improved, the charging time is shortened, and the use experience of a user is improved. In the case where the adapter does not have a charging capability to supply the target charging power, the terminal device can adapt to the adapter to realize charging with a smaller charging power.
Optionally, in step S201, determining whether the adapter has a charging capability to provide the target charging power may include:
determining whether the terminal device has a charging capability to charge at a target charging power;
in response to determining that the terminal device has a charging capability to charge at the target charging power, it is determined whether the adapter has a charging capability to provide the target charging power.
Wherein determining whether the terminal device has charging capability to charge at the target charging power may include:
determining the number of charge pumps in the terminal equipment;
in response to the number of charge pumps being greater than a preset threshold, it is determined that the terminal device has a charging capability to charge at a target charging power.
Wherein the preset threshold is determined based on the target charging power and the maximum charging power that can be allowed by the single charge pump.
The charging capability of the terminal device is illustratively determined by its own hardware structure. For example, the more charge pumps in a terminal device, the more charging capacity it has. The target charging power may be set in advance, for example, may be set to 200W. For example, as described above, 3 charge pumps may support 200W charging, 2 charge pumps may support 120W charging, 1 charge pump may support 67W charging, and if the number of charge pumps in the terminal device is 2, the terminal device itself cannot support the target charging power of 200W.
The preset threshold is preset based on the target charging power and the maximum charging power that can be allowed by the single charge pump. For example, if the target charging power is 200W and the maximum charging power that a single charge pump can allow is 70W, the preset threshold may be set to 2. If it is determined that the number of charge pumps in the terminal device is 3 and the maximum charge power allowable by the combined action of the 3 charge pumps is 210W, it may be determined that the terminal device has a charging capability to charge at the target charge power. If it is determined that the number of charge pumps in the terminal device is 2 or less, the maximum charge power that the charge pump assembly can allow cannot reach 200W, and it may be determined that the terminal device does not have the charging capability to charge at the target charge power.
Therefore, before determining whether the adapter has the charging capability for providing the target charging power, determining whether the terminal equipment has the charging capability for charging with the target charging power, so as to avoid that the power output by the adapter is larger than the maximum power which can be born by the terminal equipment due to mismatching of the set target charging power and hardware in the terminal equipment, and further ensure the operation safety of the terminal equipment.
Based on the same inventive concept, the present disclosure also provides a charging device applied to a terminal device. Fig. 5 is a block diagram of a charging device provided in an exemplary embodiment of the present disclosure. Referring to fig. 5, the charging device 600 may include:
a first determining module 601, configured to determine whether an adapter has a charging capability that provides a target charging power, where the target charging power is greater than a default charging power provided by the adapter by default;
a first sending module 602, configured to send, to the adapter, a first demand current instruction for indicating a current demand current by a first number of bits in response to determining that the adapter has a charging capability of providing the target charging power, so that the adapter charges the terminal device according to the first demand current instruction, where the first number of bits is greater than a second number of bits indicating a default use of the current demand current, and the second number of bits is capable of indicating a maximum current that is smaller than the current demand current indicated by the first demand current instruction.
In the case that it is determined that the adapter has a charging capability to provide the target charging power, the adapter may be caused to charge the terminal device according to the first demand current command by a first demand current command indicating a current demand current with a first number of bits that is greater than a second number of bits that indicates a current demand current to be used by default, the second number of bits being capable of indicating a maximum current that is less than the current demand current indicated by the first demand current command. In this way, when the terminal device has a charging requirement for a higher target charging power and the adapter has a charging capability for providing the target charging power, the higher current demand current is indicated by the extended bit number, so that the adapter can charge the terminal device according to the current demand current indicated by the extended bit number, thereby improving the charging power, shortening the charging time, and improving the use experience of the user. In addition, fast charging can be achieved by modifying the protocol (i.e., indicating a higher current demand current by an extended number of bits), and for existing adapters that support less charging power, high power fast charging can be achieved without hardware-related modifications to the adapter as long as the adapter has a charging capability that provides the target charging power.
Optionally, the first determining module 601 includes:

Optionally, the first sending module 602 is further configured to send, to the adapter, a second demand current instruction for indicating a current demand current by the second bit number in response to determining that the adapter does not have a charging capability for providing the target charging power, so that the adapter charges the terminal device according to the second demand current instruction, where the current demand current indicated by the second demand current instruction is not greater than a maximum current that can be indicated by the second bit number.
Optionally, the first determining module 601 includes:
a second determining submodule for determining whether the terminal equipment has a charging capability of charging with the target charging power;
and a third determination sub-module for determining whether the adapter has a charging capability to provide a target charging power in response to determining that the terminal device has a charging capability to charge at the target charging power.
Based on the same inventive concept, the present disclosure also provides a charging device applied to the adapter. Fig. 6 is a block diagram of a charging device provided in an exemplary embodiment of the present disclosure. Referring to fig. 6, the charging device 700 may include:
a first receiving module 701, configured to receive a charging capability identification instruction sent by a terminal device, where the charging capability identification instruction indicates a target charging current corresponding to a target charging power, where the target charging power is greater than a default charging power provided by the adapter by default;
a second sending module 702 configured to send, in response to determining that the target charging current is not greater than a maximum current that the adapter can provide, a first charging capability confirmation instruction to the terminal device, where the first charging capability confirmation instruction characterizes that the target charging current is not greater than the maximum current that the adapter can provide;
A second receiving module 703, configured to receive a first demand current instruction sent by the terminal device, where the first demand current instruction is used to indicate a current demand current of the terminal device with a first number of bits, where the first number of bits is greater than a second number of bits that indicates that the current demand current is used by default, and the second number of bits is capable of indicating a maximum current that is less than the current demand current indicated by the first demand current instruction;

In this way, when the terminal device has a charging requirement for a higher target charging power and the adapter has a charging capability for providing the target charging power, the higher current demand current is indicated by the extended bit number, so that the adapter can charge the terminal device according to the current demand current indicated by the extended bit number, thereby improving the charging power, shortening the charging time, and improving the use experience of the user. In addition, fast charging can be achieved by modifying the protocol (i.e., indicating a higher current demand current by an extended number of bits), and for existing adapters that support less charging power, high power fast charging can be achieved without hardware-related modifications to the adapter as long as the adapter has a charging capability that provides the target charging power.

the control module 704 is further configured to charge the terminal device according to the second demand current instruction.
