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 embodiments described in the following exemplary embodiments do not represent all embodiments 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.

With the rapid development of charging technology, charging performance experience of mobile terminal equipment such as smart phones is greatly improved. Currently, mobile terminals generally employ lithium batteries that are rechargeable, and thus charging the mobile terminals is a conventional operation of the mobile terminals. In order to improve cruising ability, a mobile terminal generally employs a battery with a larger capacity, and in order to charge the battery as soon as possible, a larger charging power is generally employed in charging.

However, the larger charging power can cause significant charging temperature rise, so that the situation that a user feels glowing when touching the smart phone is easy to occur, and the user experience is seriously affected. More seriously, the excessive temperature rise also easily causes the problem of the use safety of the mobile terminal. In order to solve the problem, in the related art, the charging power is usually adjusted by taking the charging temperature as an index, however, the judgment index of the scheme is too single, so that the charging power is easy to be greatly different in different temperature intervals, and the flexibility and fineness of charging regulation and control are limited. In view of this, the present disclosure provides the following charge control method, apparatus, device, and storage medium, which have solved the above-described drawbacks in the related art.

FIG. 1 is a flow chart illustrating a method of charge control according to an exemplary embodiment; the method of the present embodiment may be performed by a charging control device, which may be configured in a terminal apparatus, for example, a server, a workstation, a personal computer, a mobile terminal (e.g., a mobile phone, a tablet computer, etc.), a wearable apparatus (e.g., glasses, a wristwatch, etc.), or the like. Specifically, as shown in fig. 1, the method includes the following steps S101 to S104:

in step S101, at least one charging influence information of a terminal device is detected in response to detecting that the terminal device is in a charging in-place state.

In this embodiment, the terminal device may periodically detect whether the terminal device is in a charging state by using a polling or interrupt mechanism, and may further detect at least one charging influence information of the terminal device when detecting that the terminal device is in the charging state.

The charging influence information may include information that has an influence on a charging temperature rise of the terminal device. Illustratively, the above-described charging influence information may include at least one of: equipment power (%), equipment temperature (DEG C), equipment working scene, equipment posture and manual operation.

In some embodiments, a terminal device may be considered to be in a charging bit state when it successfully establishes a charging connection with a charging device. Specifically, when the charging of the terminal device is connected or disconnected, the level of the charging port pin changes, triggering the insertion interruption corresponding to the charging IC, so that whether the terminal device is in a charging bit state can be detected based on the change of the level of the charging port pin. In addition, the charging IC also has a specific status register to store a real-time charging status, such as charging/discharging, so that it is also possible to determine whether the terminal device is in a charging state based on the status stored in the status register.

It should be noted that the detection manner of the charging influence information may be different from that implemented in different terminal devices. For example, the device temperature may be read by a specific chip or fit calculated by a multi-location NTC (negative temperature coefficient ). For another example, the device pose may be calculated by an acceleration sensor and a magnetic field sensor acquisition. The manual operation may be through screen contact detection or camera behavior capture, etc., and will not be described in detail herein.

It can be understood that the charging influence information can be cut or added according to the actual situation of the terminal equipment, so that the expandability is strong, and the flexibility of charging control of the terminal equipment can be improved.

In step S102, charging speed adjustment information is determined based on the at least one charging influence information.

In this embodiment, after at least one type of charging influence information of the terminal device is detected, charging speed adjustment information may be determined based on the at least one type of charging influence information.

The charging speed adjustment information may be information for adjusting the charging power of the terminal device, and may be, for example, an adjustment ratio or an adjustment range of the charging power, which is not limited in this embodiment.

In some embodiments, the at least one charging influence information may be input into a pre-trained charging speed adjustment information prediction model to obtain the charging speed adjustment information. The charge speed adjustment information prediction model may be previously constructed and trained based on sample data, and the specific training method is not limited in this embodiment.

In other embodiments, the above manner of determining the charging speed adjustment information based on the at least one charging influence information may also refer to an embodiment shown in fig. 3 described below, which will not be described in detail herein.

In step S103, a target charging power is determined based on the current charging power limit of the terminal device and the charging speed adjustment information.

In this embodiment, after determining the charging speed adjustment information based on the at least one charging influence information, the target charging power may be determined based on the current charging power limit of the terminal device and the charging speed adjustment information. That is, the current charging power may be adjusted based on the charging speed adjustment information to determine the adjusted charging power as the target charging power described above.

The current charging power limit is a charging power limit applied to the charging device by the terminal device based on the state of the terminal device (i.e., the current device state of the terminal device). For example, the charging power supported by the terminal device itself is 65W, but since the current temperature of the terminal device is too high (e.g. 45 ℃ higher than the set threshold value, etc.), the charging power limit may be only 20W at this time, and then if the temperature of the terminal device is reduced to the normal range, the charging power limit may be raised to 40W.

In other embodiments, the above manner of determining the target charging power based on the current charging power limit value of the terminal device and the charging speed adjustment information may also refer to an embodiment shown in fig. 4 described below, which will not be described in detail herein.

In step S104, the terminal device is controlled to charge based on the target charging power.

In this embodiment, after determining the target charging power based on the current charging power limit value of the terminal device and the charging speed adjustment information, the terminal device may be controlled to perform charging based on the target charging power.

It can be understood that in the whole charging process, the terminal device can continuously detect whether the terminal device is in a charging in-place state or not, and detect at least one charging influence information of the terminal device when detecting that the terminal device is in the charging in-place state, and further determine the target charging power based on the charging influence information, so that the flexibility and fineness of charging control of the terminal device can be improved.

As can be seen from the foregoing description, in the method of this embodiment, in response to detecting that a terminal device is in a charging in-place state, at least one charging influence information of the terminal device is detected, and charging speed adjustment information is determined based on the at least one charging influence information, then a target charging power is determined based on a current charging power limit value of the terminal device and the charging speed adjustment information, and further the terminal device is controlled to charge based on the target charging power, so that the charging power of the terminal device can be intelligently regulated and controlled based on a change condition of the charging influence information of the terminal device, flexibility and fineness of charging control are improved, and further a problem of excessively high temperature rise in a charging process of the terminal device is effectively improved, and user experience can be improved.

Fig. 2 is a flowchart illustrating a charge control method according to another exemplary embodiment of the present disclosure; the method of the present embodiment may be performed by a charging control device, which may be configured in a terminal apparatus, for example, a server, a workstation, a personal computer, a mobile terminal (e.g., a mobile phone, a tablet computer, etc.), a wearable apparatus (e.g., glasses, a wristwatch, etc.), or the like. Specifically, as shown in fig. 2, the method includes the following steps S201 to S205:

in step S201, in response to detecting that the terminal device is in a charging in-place state, charging specification information of the terminal device is acquired.

In this embodiment, after the terminal device detects the charging in-place state, the charging specification information of the terminal device may be obtained.

The charging specification information comprises information related to the current charging specification, which is acquired from the charging equipment based on the current charging connection by the terminal equipment.

For example, the charging specification information may include, but is not limited to: charging protocol type, upper limit of charging power, vendor specific identification, etc. The vendor specific identifier may include a generic vendor ID and/or a vendor custom identifier, such as an authentication identifier for a specific charging specification, etc.

In some embodiments, the charging specification information may be actively read from the charging device or passively received by the terminal device when the charging connection is successfully established, which is not limited in this embodiment.

In step S202, at least one type of charging influence information of the terminal device is detected in response to the charging specification information satisfying a setting condition.

In this embodiment, after the charging specification information of the terminal device is obtained, whether the charging specification information meets a set condition may be determined, and when it is determined that the charging specification information meets the set condition, the terminal device may be controlled to enter a charging control preparation mode; in this mode, the terminal device may detect at least one charging influence information of the terminal device. The charging influence information may include information that has an influence on a charging temperature rise of the terminal device.

It should be noted that, the above-mentioned charge control preparation mode may be a mode of a transition state of the terminal device, where the above-mentioned charge specification information satisfies a set condition, but the charging effect of at least one currently detected charge influence information of the terminal device is not yet effective, and the subsequent calculation of the charge speed adjustment information and the target charge power is required, and then the application is effective, and the actual working state is entered (i.e. the terminal device is charged based on the calculated target charge power). It is to be understood that in the above-described charge control preparation mode, the charge setting that is actually in effect may be the previous setting, such as the target charge power determined previously or the charge power in the normal charge control mode.

The setting conditions met by the charging specification information can be set according to the actual supporting situation of the terminal equipment.

Taking the charging protocol type as an example, the charging protocol type can include general charging and fast charging, such as USBBC1.2 protocol, high-pass QC fast charging protocol, MTKPE fast charging protocol, USBPD/PPS protocol, etc., if the terminal device only supports several fast charging types, and the charging protocol type identified by the charging connection is not in the list, the information can be considered as not meeting the condition; in contrast, if the charging protocol type identified by the current charging connection is listed in this column, the charging specification information may be considered to satisfy the condition.

Taking the upper limit of the charging power as an example, the terminal equipment can have different upper limits of the charging power under the protocol type supported by the terminal equipment, if the upper limit of the charging power under the PD protocol type supported by the terminal equipment is 67W, and the condition is only met if the upper limit of the charging power is set to be more than 33W, and the charging connection recognizes that the charging power under the PD protocol type is only 20W, the information can be considered to not meet the condition; in contrast, if the present charging connection recognizes that there is 40W of charging power under the PD protocol type, the information may be considered to satisfy the condition.

Similarly, if the terminal device supports a vendor specific identifier, it may be set that the condition is satisfied only if the identifier is recognized, and if the specific identifier is not recognized by the charging connection, the information may be considered as not satisfying the condition.

On this basis, in the case that the above-mentioned various charging specification information satisfies the respective conditions, it may be determined that the charging specification information satisfies the set conditions, and further, the operation of subsequently detecting at least one type of charging influence information of the terminal device may be performed.

It can be understood that by presetting the setting conditions of the charging specification information and determining after obtaining the charging specification information of the terminal device, the implementation timing of the charging control scheme of the embodiment can be further limited, so as to ensure the safety of charging the terminal device.

In other embodiments, if the charging specification information does not meet the set condition, the above-mentioned detection of at least one charging influence information of the terminal device and the subsequent steps S203 to S205 may not be performed, and the terminal device may be controlled to be charged based on a conventional charging control manner in the related art, which is not limited in this embodiment.

In step S203, charging speed adjustment information is determined based on the at least one type of charging influence information.

In step S204, a target charging power is determined based on the current charging power limit of the terminal device and the charging speed adjustment information.

In step S205, the terminal device is controlled to charge based on the target charging power.

The explanation and explanation of the steps S203 to S205 may be referred to the steps S102 to S104 in the embodiment shown in fig. 1, which are not described herein.

As can be seen from the foregoing description, in the method of this embodiment, in response to detecting that a terminal device is in a charging in-place state, charging specification information of the terminal device is obtained, and in response to the charging specification information meeting a set condition, at least one charging influence information of the terminal device is detected, so that a subsequent determination of charging speed adjustment information based on the at least one charging influence information and a determination of a target charging power based on a current charging power limit value of the terminal device and the charging speed adjustment information can be implemented, thereby, charging of the terminal device based on the target charging power can be controlled, intelligent regulation of charging power of the terminal device based on a change condition of the charging influence information of the terminal device can be implemented, flexibility and fineness of charging control can be improved, and further, a problem of excessively high temperature rise in a charging process of the terminal device can be effectively improved, and user experience can be improved.

Further, after detecting at least one type of charging influence information of the terminal device, the speed regulation information corresponding to each type of charging influence information may be determined based on the correspondence.

Taking at least one charging influence information including equipment electric quantity, equipment temperature, equipment working scene, equipment posture and manual operation as an example, the following corresponding relationship shown in the first table may be constructed in advance:

As shown in fig. 4, the determining the target charging power based on the current charging power limit value of the terminal device and the charging speed adjustment information described in the above step S103 may include the following steps S401 to S402:

in step S401, a charge power increase amount is determined based on the current charge power limit value and the charge speed adjustment information.

In this embodiment, after the charging speed adjustment information is determined based on the at least one charging influence information, the charging power increase amount may be determined based on the current charging power limit value and the charging speed adjustment information.

In some embodiments, the above-described charge power increase amount may be determined based on a product of the current charge power limit and the charge speed adjustment information.

FIG. 5 is a flowchart illustrating how to determine the target charging power based on the current charging power limit and the charge power increase amount according to an exemplary embodiment of the present disclosure; the present embodiment is exemplified on the basis of the above-described embodiments by taking as an example how the target charging power is determined based on the current charging power limit value and the charging power increase amount.

As shown in fig. 5, the determining the target charging power based on the current charging power limit and the charging power increment described in the above step S402 may include the following steps S501 to S502:

The upper limit of the charging power may be the highest charging power determined by the terminal device after negotiating with the charging device based on the current charging connection.

For example, if the terminal device supports 65W of charging power and the charger supports 120W of charging power, after the terminal device and the charger are connected by charging, three gears of 5V3A, 9V3A and 5-10V 6.5a can be negotiated and provided, and on the basis, the upper limit of the charging power corresponding to the current charging connection can be determined to be 65W.

In step S502, the target charging power is determined based on the smaller of the charging power upper limit and the sum of the current charging power limit and the charging power increase amount.

In this embodiment, after the charging power upper limit corresponding to the current charging connection is obtained, the target charging power may be determined based on the smaller of the charging power upper limit, the current charging power limit, and the sum of the charging power increment.

For example, if the upper limit of the charging power isThe sum of the current charging power limit value and the charging power increment is +.>The target charging power can be determined based on the following formula (5-1)>；

As shown in fig. 6, the method of the present embodiment includes the following steps 601-610:

in step 601, a trigger condition of a first charging mode is set first;

In step 602, the charging bit status of the terminal device is monitored.

The detection manner of the charging in-place state may refer to the embodiment shown in fig. 1, and will not be described herein.

In step 603, it is determined whether the terminal device is in a charging in-place state: if yes, go to step 604; if not, step 602 is performed.

In step 604, charging specification information of the terminal device is acquired.

The charging specification information includes information related to the current charging specification, which is obtained by the terminal device from the charging device based on the current charging connection, and the specific content may be referred to the embodiment shown in fig. 2, which is not described herein.
