Referring to fig. 1, fig. 1 is a flowchart illustrating a charging control method according to an embodiment.
In this embodiment, the main execution body of the charging control method is an electronic device, and the electronic device may be, for example, a mobile phone, a tablet computer, and a wearable device. As shown in fig. 1, the charging control method includes steps 102 to 106.
The charging equipment comprises standard equipment matched with the electronic equipment and non-standard equipment unmatched with the electronic equipment, and the standard equipment is original charging equipment matched with various charging requirements of the electronic equipment. The charging device can be a power adapter or a charger, and the charging device can be a wired charging device or a wireless charging device. When the charging device is a wired charging device, the electronic device and the charging device can perform bidirectional communication based on the transmission line; when the charging device is a wireless charging device, the electronic device and the charging device may communicate bi-directionally over a wireless link.
The standard equipment is matched with various charging requirements of the electronic equipment, so that safe charging can be directly carried out; the non-standard equipment is not completely matched with various charging requirements of the electronic equipment, certain potential safety hazards exist in the charging process, and the charging parameters of the charging equipment need to be limited in the charging process.
When the electronic device is connected with the charging device, the device type of the charging device can be identified by acquiring the device identifier of the charging device, and the device type of the charging device can also be identified by setting the detection circuit to detect the charging parameter of the charging device. In an embodiment, when the electronic device detects a charging signal, for example, when the electronic device detects a change from low to high in a voltage signal of the USB port, it is determined that the electronic device is connected to the charging device, so as to obtain device identification information of the charging device or detect a charging parameter of the charging device through a data transmission function of the USB port.
And 104, acquiring the charging state information of the electronic equipment when the equipment type is the non-standard equipment.
When the device type is non-standard equipment, in order to prevent safety accidents caused by charging of the non-standard equipment, the electronic device needs to acquire charging state information in real time or within preset time to monitor the charging condition, and the safety of the charging process is ensured.
In one embodiment, the charging state information includes temperature information, current charging voltage value, current charging current value, power information, and the like of the electronic device. The temperature information of the electronic device may be a battery temperature value of the electronic device or a charging port temperature value. In one embodiment, the electronic device is provided with a detection circuit for detecting the current charging state information, and the detection circuit may include a temperature sensing circuit, a voltage detection circuit, a current detection circuit, a power detection circuit, and the like.
And step 106, adjusting the charging parameters for charging the electronic equipment according to the charging state information.
When the device type is non-standard distribution device, in order to prevent the occurrence of safety accidents caused by charging of the non-standard distribution device, besides the charging condition is monitored, the charging parameters also need to be adjusted in real time according to the charging state information, and the safety of the charging process is ensured.
In an embodiment, the electronic device has a charging management function, for example, the electronic device is provided with a charging management circuit capable of directly limiting a charging current of the charging device, and step 106 may specifically be to control the charging management circuit to adjust a charging parameter according to the charging status information. In an embodiment, the charging device is provided with a control circuit, the electronic device generates an adjustment instruction according to the charging state information and the required charging requirement, and instructs the control circuit of the charging device to adjust the charging parameter, and step 106 may specifically be sending a corresponding adjustment instruction to the charging device according to the charging state information, where the adjustment instruction is used to instruct the charging device to adjust the charging parameter.
In an embodiment, referring to fig. 2, step 102 includes steps 202 to 206.
The equipment identification information can be used for verifying the identity information of the charging equipment, and whether the charging equipment is standard equipment or non-standard equipment can be judged through the identity information. The device identifier may be default settings for factory, and includes one or more information of a device model of the charging device, a charging voltage range, a charging current range, a model of an electronic device that can be charged, and the like. In an embodiment, a communication connection is established between the electronic device and the charging device, the electronic device sends an inquiry instruction to inquire the device identification information of the charging device, and the charging device returns the device identification information of the charging device according to the inquiry instruction. And if the electronic equipment does not receive the equipment identification information returned by the charging equipment within the preset time or the preset times after sending the query instruction, the default charging equipment is the non-standard equipment.
And step 204, when the equipment identification information is matched with the standard equipment identification information, judging that the equipment type is the standard equipment.
And step 206, when the equipment identification information is not matched with the standard equipment identification information, judging that the equipment type is a non-standard equipment.
When the equipment identification information of the charging equipment is matched with the identification information of the standard equipment, the charging equipment is judged to be the standard equipment; and when the equipment identification information of the charging equipment is not matched with the standard equipment identification information, judging that the charging equipment is non-standard equipment.
For example, when the device identification information includes one or more types of information such as a device model, a charging voltage range, a charging current range, and a chargeable electronic device model, the electronic device verifies, through the device identification information, whether the one or more types of information match with the standard device identification information stored in the electronic device for selection, and if the one or more types of information match with the standard device identification information stored in the electronic device, the charging device is a standard device; and if not, the charging equipment is non-standard equipment.
Therefore, in step 102, the device type of the charging device can be identified by comparing the device identification information of the charging device with the standard device identification information, and the current charging state of the electronic device is further confirmed.
In one embodiment, the charging status information includes temperature information of the electronic device, please refer to fig. 3, and step 106 includes steps 302 to 304.
The temperature information of the electronic device may be battery temperature information of the electronic device, or may be charging port temperature information.
Wherein the first temperature threshold and the second temperature threshold can be set according to the heat resistance degree of the battery or the charging port of the electronic device. When the temperature information is below the first temperature threshold, the safety of charging the electronic equipment is high; when the temperature information is between the first temperature threshold and the second temperature threshold, the safety of charging the electronic device is high.
When the first current threshold value corresponds to a current value with a temperature value smaller than the first temperature threshold value, the charging time length can be shorter under the condition of safe charging; the second current threshold, which is smaller than the first current threshold, corresponds to a current value at which the charging time period can be made shorter under the safe charging condition when the temperature value is in a range between the first temperature threshold and the second temperature threshold.
Specific values of the first current threshold, the second current threshold, the first temperature threshold, and the second temperature threshold are set according to actual conditions, and are not limited herein. Wherein the second current threshold may be 70% of the first current threshold.
When the temperature information is smaller than the first temperature threshold, the charging current is adjusted to be the first current threshold, so that the charging equipment can be charged safely and the charging time is short; when the temperature information is larger than the first temperature threshold and smaller than the second temperature threshold, the charging current is adjusted to be the second current threshold, so that the charging equipment can be charged safely and the charging time is short. After the charging current is adjusted to be the second current threshold, if the temperature information is detected to be smaller than the first temperature threshold again, the charging current can be adjusted to be the first current threshold again.
For example, the first temperature threshold is 37 ℃, the second temperature threshold is 40 ℃, the first current threshold is 2A, and the second current threshold is 1.5A. Limiting the charging current to 2A when the temperature value is lower than 37 ℃; the charging current is limited to 1.5A when the temperature value is greater than 37 ℃ and less than 40 ℃ until the temperature value is less than 37 ℃, and the charging current can be limited to 2A again.
In an embodiment, please refer to fig. 3, step 106 further includes step 306.
And step 306, terminating charging when the temperature information is above the second temperature threshold, and outputting fifth prompt information, wherein the fifth prompt information is used for prompting that the current charging state is a dangerous state and prompting a user to disconnect the power supply of the charging equipment first and then disconnect the charging equipment from the electronic equipment.
When the temperature information is above the second temperature threshold, the temperature of the whole electronic equipment is high, charging is dangerous, charging is stopped, and fifth prompt information is output to prompt a user that the current charging state is a dangerous state and prompt the user to perform related power-off operation, so that the charging safety is improved.
In order to enable the user to have more visual auditory sense or visual sense relative to the fifth prompt information so as to clearly prompt the user, the fifth prompt information is one or more of character prompt information, image prompt information and sound prompt information. For example, when the fifth prompt message is a text prompt message, a prompt message "danger, end charging, please disconnect the power of the power adapter first, and then unplug the USB port of the power adapter" may be displayed.
Therefore, step 106 correspondingly adjusts the charging parameters according to the charging state information, so as to prevent safety accidents caused by charging of non-standard equipment and ensure the safety of the charging process; and when the temperature of the whole electronic equipment is higher, the charging is stopped, and the current charging state of the user is prompted to be a dangerous state so that the user can carry out related power-off operation, and the charging safety is further ensured.
According to the charging control method provided by the embodiment, the device type of the charging device is acquired when the charging device is connected, the charging state information is acquired when the device type is a non-standard device, and the charging parameter for charging the electronic device is adjusted according to the charging state information, so that safety accidents caused by charging of the non-standard device are prevented, and the safety of the charging process is ensured.
Referring to fig. 4, fig. 4 is a flowchart illustrating a charging control method according to an embodiment. As shown in fig. 4, the charging control method includes steps 402 to 410.
And step 404, when the device type is a non-standard device, acquiring the charging state information of the electronic device.
In step 406, the charging parameters for charging the electronic device are adjusted according to the charging status information.
In this embodiment, steps 402 to 406 correspond to steps 102 to 106 in the above embodiment one to one, and are not described herein again.
And step 408, outputting first prompt information when the device type is a non-standard device, wherein the first prompt information is used for prompting that the current charging state of the electronic device is a dangerous latent state. The dangerous latent state means that potential safety hazards exist when the current charging equipment charges the electronic equipment.
Specifically, when the charging equipment is non-standard configuration equipment, potential safety hazards exist when the charging equipment charges the electronic equipment, the first prompt information is used for prompting a user that the charging equipment is the non-standard configuration equipment, and the current charging state is a dangerous latent state, so that the user is reminded of paying attention to the charging condition. The first prompt message may be one or more of a text prompt message, an image prompt message, an audio prompt message, or a vibration prompt message, so that the user may visually and/or audibly receive the first prompt message output by the electronic device.
In an embodiment, the first prompt message at least includes the current charging status information, and in some other embodiments, in addition to the important prompt message of the current charging status information, some other secondary prompt messages may be included, for example, some messages may be included to prompt the user how to perform the safety operation currently. In order to highlight the level degree of the prompt information, the prompt information of different levels may be set differently, for example, when the first prompt information is a text prompt information, the important prompt information may be displayed in red, and the other secondary prompt information may be displayed in black.
For example, when the first prompt message is a text prompt message, a red prompt message "non-standard equipment and please pay attention to charging safety" may be displayed, and a black prompt message "the user does not use the electronic equipment and pays attention to the charging condition at any time during the charging process" may be displayed.
And step 410, outputting second prompt information when the device type is standard configuration equipment, wherein the second prompt information is used for prompting that the current charging state is a safe state.
Specifically, when the charging device is a standard matching device, the charging device can safely charge the electronic device without acquiring the charging state information in the charging process or adjusting the charging parameters according to the charging state information. The second prompt message is used for prompting the user that the current charging state is a safe state, and the user does not need to pay attention to the charging situation all the time.
The second prompt message may be one or more of a text prompt message, an image prompt message, an audio prompt message, or a vibration prompt message. For example, when the first prompt message is a text prompt message, a prompt message of "standard equipment, charging safety" may be displayed.
The second prompt message is different from the first prompt message in prompt content, for example, when the first prompt message and the second prompt message are both text messages, the second prompt message is different from the first prompt message in text messages; for example, when the first prompt message and the second prompt message are both vibration prompt messages, at least one of the vibration frequency, the vibration amplitude and the vibration duration of the second prompt message and the first prompt message is different.
In the charging control method provided by this embodiment, the device type of the charging device is identified when the charging device is connected to the charging device, on one hand, when the device type is a non-standard device, a first prompt message is output to prompt that the current charging state is a dangerous latent state, so as to prompt a user to pay attention to the charging condition; and in the charging process, the charging state information is acquired to adjust the charging parameters, so that safety accidents caused by charging of non-standard equipment are prevented, and the safety of the charging process is ensured. On the other hand, when the device type is the standard configuration device, the second prompt information is output to prompt that the current charging state of the user is the safe state, the charging device can safely charge the electronic device, and the user can use the electronic device with confidence.
Referring to fig. 5, fig. 5 is a flowchart illustrating a charging control method according to an embodiment. As shown in fig. 5, the charging control method includes steps 502 to 508.
In step 506, the charging parameters for charging the electronic device are adjusted according to the charging state information.
In this embodiment, steps 502 to 506 correspond to steps 102 to 106 in the above embodiment one to one, and are not described herein again.
And step 508, terminating charging when the charging state information meets the charging completion condition, and outputting third prompt information, wherein the third prompt information is used for prompting a user to disconnect the power supply of the charging equipment first and then disconnect the charging equipment and the electronic equipment, so that the user is prompted to perform safe power-off operation. For example, the user is prompted to disconnect the power of the power adapter first and then unplug the USB port of the power adapter connected to the electronic device.
The third prompt message is different from the first prompt message and the second prompt message in content, and the prompt form may be the same or different. In order to enable the user to have more intuitive auditory sense or visual sense relative to the third prompt information so as to clearly operate the prompt, the third prompt information is one or more of character prompt information, image prompt information and sound prompt information. For example, when the third prompt message is a text prompt message, a prompt message "complete charging, disconnect the power supply of the power adapter first, and then unplug the USB port of the power adapter" may be displayed.
In an embodiment, the charging state information includes electric quantity information, and when the electric quantity information satisfies the charging completion condition, the current charging state is determined to be the charging completion state, and the user is prompted to perform a related power-off operation. The measurement of the power information may be a value of a current power of the electronic device, or a ratio of the current power of the electronic device to a battery capacity, such as a current power percentage. The measure of the power threshold is consistent with the measure of the power information.
In an embodiment, please refer to fig. 6, wherein step 508 includes steps 602 to 606.
When detecting that the electric quantity information of the electronic equipment reaches the first electric quantity threshold value, in order to prolong the service life of the battery, the current electric quantity value of the electronic equipment can be defaulted to meet the basic electricity storage requirement and belong to a full-electricity state, so that fourth prompt information is output to remind a user whether the charging process needs to be terminated. For example, the first preset charge threshold is 80%.
The fourth prompt message can be output in the form of text message, image message or sound message, so that the user can visually obtain the fourth prompt message. For example, the fourth prompting message may be directly displayed on the display screen of the electronic device, and may be accompanied by an answering option for the user to answer. The response options comprise a charging termination option and a charging continuation option, and the user can directly select the corresponding options on the display screen so as to feed back corresponding response information.
And step 604, terminating charging when the charging termination instruction is received, and outputting third prompt information.
And step 606, continuing to charge when the charging continuation instruction is received, terminating charging when the electric quantity information reaches the second electric quantity threshold value, and outputting third prompt information.
When a charging termination instruction is received, judging that the current charging is in a charging completion state, terminating charging, and outputting third prompt information; and when a charging continuation instruction is received, judging the current unfinished charging state, continuing charging until the electric quantity information of the electronic equipment reaches a second electric quantity threshold value, and directly terminating the charging process in order to prevent the battery from being overcharged and consider that the electric quantity value meets the full-charge requirement. For example, the second preset charge threshold is 99%. It should be noted that, when no instruction input by the user is received within the preset time, the current charging completion state is defaulted, the charging is terminated, and the third prompt message is output.
Therefore, in step 508, the battery of the electronic device can be protected by setting the first electric quantity threshold and the second electric quantity threshold, so that charging safety is realized, energy consumption is reduced, and charging time is shortened; the third prompt information is output in the two charging completion states, so that the user can know the charging completion condition, and the user is prompted to perform correct power-off operation, and the charging safety is further improved.
It should be noted that the second electric quantity threshold may also be directly set, and when the electric quantity information of the electronic device reaches the second electric quantity threshold, the third prompt information is directly output, so that the user can know the charging completion condition, and is prompted to perform a correct power-off operation, thereby further improving the charging safety.
In the charging control method provided by this embodiment, the device type of the charging device is identified when the charging device is connected to the charging device, on one hand, when the device type is a non-standard device, in the charging process, the charging state information is obtained, and the charging parameter is adjusted according to the charging state information, so that a safety accident caused by charging of the non-standard device is prevented, and the safety of the charging process is ensured; on the other hand, when the charging is finished, the current charging state is prompted to be the charging finished state, and a user is prompted to carry out related power-off operation, so that the charging safety is further improved.
It should be understood that although the various steps in the flow charts of fig. 1-6 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.

It should be noted that the different embodiments described above may be combined with each other.
