Description
Technical Field
The present disclosure relates to the field of electronic devices, and in particular, to a charging method, apparatus, system, electronic device, and storage medium.
Background
Many electronic devices are used in daily life, and generally, the electronic devices include terminals and chargers. Taking a mobile phone as an example, when the mobile phone is used for a period of time and the electric quantity is insufficient, a charger needs to be used for charging.
Each charger has a limit power value and a nominal power. When the charging power of the charger exceeds the limit power value, the overload protection in the charger can immediately interrupt charging, and circuit damage is avoided. When the charger works normally, the charging power is smaller than the limit power. And the nominal power is the charging power at which the charger can operate for a long time and malfunction with a low probability. To ensure that the charger can work properly, the charger will actually be able to provide a larger charging power than the nominal power, which may cause the actual charging power of the charger to exceed the nominal power.
When the mobile phone is charged, the mobile phone mainly comprises three stages of pre-charging, constant-current charging and constant-voltage charging, wherein the charging power is the maximum during the constant-current charging. As the power consumption of the mobile phone is larger and larger, the capacity of the battery is larger and larger, and the time required for charging is longer as the capacity of the battery is larger. In order to shorten the charging time, the charging power of the charger during the constant current charging phase is as large as possible without exceeding the limit power value, which makes the charger often work in an out-of-limit state, i.e. the charging power exceeds the nominal power of the charger. If the charger works in an overproof state for a long time, the service life of the charger is shortened, the temperature of the charger is overhigh, and potential safety hazards are possibly formed.

Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
For ease of understanding, the charging process of the charging system is described below.
The charging system comprises a terminal and a charger. The terminals are typically provided with an off-the-shelf charger, but in use the terminals may be charged using a number of different types of chargers. Taking the terminal as a mobile phone as an example, the mobile phone is configured with an original charger matched with the brand, manufacturer and model of the mobile phone. Fig. 1 illustrates the variation of parameters including battery voltage and charging current during the charging of a terminal. In fig. 1, the abscissa is the charging time, the ordinate is the intensity corresponding to each parameter, the broken line represents the battery voltage, and the solid line represents the charging current. As shown in fig. 1, the charging of the battery can be generally divided into four processes: pre-charge, constant current charge, constant voltage charge, and charge termination.
The four processes are described below:
pre-charging: the pre-charging is used for pre-charging the battery unit which is completely discharged with small current so as to achieve the purpose of protecting the battery. Pre-charging is employed when the battery voltage is below a pre-charge voltage threshold, which is typically 0.1C, which is one tenth of the constant current charging current. C is a representation of the nominal capacity of the battery versus current, e.g., a battery with a capacity of 1000mAh, 1C is a charging current of 1000mA, and the pre-charging current of 0.1C is 100 mA. The precharge process is an optional process.
And (4) constant current charging, namely, when the voltage of the battery rises above a pre-charging voltage threshold value, increasing the charging current to perform constant current charging. The current for constant current charging is typically between 0.2C and 1.0C. During the constant current charging process, the equivalent internal resistance of the battery in the charging circuit is gradually increased. Since the charging current is equal to the charging voltage divided by the equivalent internal resistance, the charging voltage needs to be adjusted in real time in the process in order to ensure that the charging current is constant under the condition that the equivalent internal resistance is gradually increased. During the constant current charging, the battery voltage gradually rises.
Constant voltage charging: when the battery voltage rises to a final voltage, typically 3.0V to 4.2V, constant current charging ends and a constant voltage charging phase begins. In the constant voltage charging process, the charging voltage needs to be adjusted in real time to be a fixed value. In the process, the equivalent internal resistance of the battery in the charging circuit is continuously increased, the charging current is inversely proportional to the equivalent internal resistance, the charging current is gradually reduced from the maximum value, and when the charging current is reduced to 0.01C, the constant-voltage charging process is ended.
And (3) terminating charging: after the constant voltage charging process is finished, the charging is stopped. But in some cases, such as when the battery voltage is detected to be below the recharge voltage threshold, recharging will occur.
Fig. 2 is a charging curve of a charger, and fig. 2 shows two stages of constant current charging and constant voltage charging. The curve a shows the change of the charging voltage of the charger during the charging process, the curve b shows the change of the charging current of the charger during the charging process, and the product of the charging voltage and the charging current is the charging power. The charging power referred to in this disclosure refers to the charging power in the constant current charging process. The nominal power of the charger is 18W, but it can be found from the charging curve that the charging power of the charger exceeds 18W for a longer time, even reaches 19W, within a time period of about 40 minutes (i.e. a constant current charging phase). The charger works in an overproof state for a long time, the service life of the charger can be shortened, and meanwhile, the temperature of the charger is overhigh, so that potential safety hazards are formed.
Fig. 3 is a block diagram of a charging device according to an embodiment of the present disclosure. The charging device may be a terminal. As shown in fig. 3, the charging device 300 includes an acquisition module 12, a signal determination module 13, and a signal output module 14. The obtaining module 12 is configured to obtain an identification code of the charger. The signal determining module 13 is configured to determine charging indication information according to the identification code, where the charging indication information is used to indicate charging power, and the charging power indicated by the charging indication information does not exceed a nominal power of the charger. The signal output module 14 is configured to send the charging indication information to the charger, so that the charger charges at the charging power indicated by the charging indication information.
By acquiring the identification code of the charger, the charging indication information corresponding to the acquired identification code can be determined, and the charging device can send the charging indication information to the charger, so that the charger can charge the terminal with the charging power indicated by the charging indication information. Because the identification code of the charger, the charging indication information and the charging power indicated by the charging indication information are mutually corresponding, different chargers can charge the terminal with the charging power corresponding to the charger, and the charging power does not exceed the nominal power of the charger, so that the service life of the charger can be prolonged, and the use safety degree is improved.
Alternatively, the charging indication information may be a number or identification corresponding to the charging power.
Optionally, the signal determination module 13 may include a storage sub-module 131 and a processing sub-module 132. The storage submodule 131 may be configured to store a corresponding relationship between the identification code and the charging indication information. The processing sub-module 132 may be configured to determine the charging indication information corresponding to the identification code of the charger according to the correspondence between the identification code and the charging indication information. By storing the correspondence between the identification code and the charging instruction information in the storage sub-module 131 in advance, the charging instruction information corresponding to the identification code of the charger can be accurately determined when the terminal is connected to the charger.
The identification codes correspond to the chargers one to one, and different charger identification codes are different. The corresponding relation between the identification code and the charging indication information can be obtained according to experiments. For example, the nominal power of different chargers may be measured first, the charging power may be set according to the nominal power, and then the charging indication information may be set corresponding to different charging powers, so as to obtain the corresponding relationship between the identification code and the charging indication information.
The identification codes of different chargers may correspond to the same charging indication information or may correspond to different charging indication information. Fig. 4 is a schematic diagram of a correspondence relationship between identification codes and charging indication information according to an embodiment of the disclosure, where in fig. 4, a1, a2, A3, B1, B2, and B3 represent different identification codes. As shown in fig. 4, when the identification codes are included in the first identification code set 31, the identification codes correspond to the first charging indication information. When the identification code is included in the second identification code set 32, the identification code corresponds to the second charging indication information, and the charging power indicated by the first charging indication information is greater than the charging power indicated by the second charging indication information. Since there may be a plurality of chargers capable of charging the same terminal, the chargers may be different from each other, and it is possible that when some chargers are charging the terminal, it is also possible to ensure safety by using a higher charging power, and when another charger is charging the terminal, it is possible to ensure safety only by using a lower charging power.
Further, when the identification code is included in neither the first identification code set 31 nor the second identification code set 32, the identification code may correspond to third charging indication information, and the charging power indicated by the second charging indication information is greater than the charging power indicated by the third charging indication information. The types of chargers are many, it is difficult to exhaust all chargers connectable to the terminal from the first identification code set 31 and the second identification code set 32, and for chargers whose identification codes are included in neither the first identification code set 31 nor the second identification code set 32, charging may be performed with a lower charging power indicated by the third charging indication information to ensure safety. Since the identification codes of the charger are not included in the first identification code set 31 and the second identification code set 32, it is indicated that the nominal power of the charger is not determined, and the charging power indicated by the third charging indication information can be used for charging, thereby improving the safety.
For example, the charging power indicated by the first charging indication information may be 18W, the charging power indicated by the third charging indication information may be 5W, and the charging power indicated by the second charging indication information is between 5W and 18W, and may be 10W, for example. The charging power may be set according to the nominal power of the charger, for example, the charging power indicated by the first charging indication information of the charger may be 85% to 95% of the nominal power of the charger, and the charger may have a certain fluctuation in the power output by the charger during the actual charging process, and the charging power is set slightly smaller than the nominal power, so that the power output by the charger may be prevented from exceeding the nominal power when fluctuating, and meanwhile, the charger may be prevented from being insufficiently utilized due to too small charging power setting, which may result in an excessively long charging time. In a common terminal, such as a mobile phone, when charging, the nominal power of the connected charger is usually not lower than 5W, and for a charger whose identification codes are not included in the first identification code set 31 and the second identification code set 32, setting the charging power to 5W can ensure safety.
When the charging power indicated by the first charging indication information is used for charging, the charging current can be 85% -95% of the nominal current of the charger, the charging current is set to be slightly smaller than the nominal current, the current output by the charger can be prevented from exceeding the nominal current when fluctuating, and the service life of the charger can be further prolonged.
In a possible implementation manner of the embodiment of the present disclosure, the terminal may further include a data updating module 15. The data updating module 15 is configured to update the corresponding relationship between the identification code and the charging indication information. With the development of production, new chargers are continuously generated, so that the corresponding relation between the identification codes stored in the storage submodule 131 and the charging indication information can be updated, and more chargers can charge the terminal conveniently. For the produced charger, the product defects may be found in the future, so that the potential safety hazard can be further reduced by updating the corresponding relation between the identification code stored in the storage sub-module and the charging indication information.
For example, the data updating module 15 may update the corresponding relationship between the identification code stored in the storage sub-module 131 and the charging indication information through wired communication or wireless communication. Taking a mobile phone as an example, the mobile phone may establish a connection with the cloud server, and update the correspondence between the identification code stored locally and the charging instruction information in a patch downloading manner.
Optionally, when the data updating module 15 updates the corresponding relationship between the identification code and the charging indication information, at least one of the following manners may be adopted:
at least one identification code is removed from the first set of identification codes or from the second set of identification codes.
At least one of the first set of identifiers is transferred to a second set of identifiers.
At least one of the second set of identifiers is transferred to the first set of identifiers.
At least one identification code included in neither the first set of identification codes nor the second set of identification codes is added to the first set of identification codes or the second set of identification codes.
With the development of production, some existing chargers may not be able to continue to charge the terminal with the charging power indicated by the first charging indication information or the second charging indication information due to the discovery of the existence of a product defect, and the like, and therefore, the identification codes may be extracted from the first identification code set or the second identification code set. Part of the chargers which can be charged by the charging power indicated by the first charging indication information can only be charged by the charging power indicated by the second charging indication information; part of the chargers originally charged by the charging power indicated by the second charging indication information can also be charged by the charging power indicated by the first charging indication information; for the chargers corresponding to the identification codes which are not originally contained in the first identification code set and the second identification code set, after verification, the chargers can be charged by using the charging power indicated by the first charging indication information or the charging power indicated by the second charging indication information, so that the identification codes can be added into the first identification code set and the second identification code set.
Fig. 5 is a diagram of a correspondence relationship between an identification code and charging indication information according to an embodiment of the disclosure, and the correspondence relationship is updated in fig. 4. As shown in fig. 5, the identification code a1 is removed from the first set of identification codes 31. Since it is found that the charger corresponding to the identification code a1 is defective after the correspondence diagram shown in fig. 4, there is a risk that charging is performed using the charging power indicated by the first charging instruction information, the identification code a1 is removed from the first identification code set 31 after updating, so that a lower charging power corresponding to the third charging instruction information is adopted when the terminal is charged using the charger corresponding to the identification code a1 after updating. The identifier B1 originally contained in the second set of identifiers 32 is transferred to the first set of identifiers 31. Since there is an erroneous operation when the charging power of the charger corresponding to the identification code B1 is set when the correspondence diagram shown in fig. 4 is obtained, and the charging power setting is too small, when the charging power of the charger corresponding to the identification code B1 is reset, it is found that the charger can be charged with the charging power indicated by the first charging instruction information, and safety can be ensured, and therefore, the identification code B1 is shifted from the second identification code set 32 to the first identification code set 31, so as to increase the charging speed. The first identification code set 31 and the second identification code set 32 are respectively added with an identification code C1 and an identification code C2, because the charger which is not detected before is detected, the charger corresponding to the identification code C1 can be charged by the charging power indicated by the first charging indication information, the charger corresponding to the identification code C2 can be charged by the charging power indicated by the second charging indication information, the identification code C1 is added to the first identification code set 31, the identification code C2 is added to the second identification code set 32, so that after the corresponding relation between the identification code and the charging indication information is updated, when the charger corresponding to the identification code C1 is used for charging the terminal, the charging power indicated by the third charging indication information is not used for charging, but the charging power indicated by the first charging indication information is used for charging, the charging speed is improved. The identifier C2 is also added to the second set of identifiers 32 for the same reason.
The identification code may be a code set according to at least one of hardware information, software information, a production lot, and a production factory of the charger. Different hardware and software have an influence on the nominal power of the charger, the nominal power of the chargers of different batches in the same manufacturer may be different, and the nominal power of the chargers of the same model in different manufacturers may be different. Setting the identification code based on these pieces of information makes it possible to set the charging power corresponding to the identification code reasonably and shorten the charging time as much as possible on the premise of safety.
In the embodiment of the present disclosure, only the first charging indication information, the second charging indication information, and the third charging indication information are exemplarily set, and more different charging indication information may be set in production, where each different charging indication information corresponds to a different charging power and a different identification code set. The identification code of the original charger at the same terminal is different from the identification code of the non-original charger.
Fig. 6 is a block diagram of a charging device according to an embodiment of the present disclosure. The charging device may be a charger. As shown in fig. 6, the charging device 600 includes a charging module 23 and a control module 21. The control module 21 is configured to receive charging indication information sent by the terminal, where the charging indication information is used to indicate charging power, and the charging indication information is determined according to an identification code obtained after the terminal obtains the identification code of the charger.
The charging module 23 is configured to charge the terminal with the charging power indicated by the charging indication information, where the charging power indicated by the charging indication information does not exceed the nominal power of the charger.
By acquiring the identification code of the charger, the charging indication information corresponding to the acquired identification code can be determined, and the charging device can send the charging indication information to the charger, so that the charger can charge the terminal with the charging power indicated by the charging indication information. Because the identification code of the charger, the charging indication information and the charging power indicated by the charging indication information are mutually corresponding, different chargers can charge the terminal with the charging power corresponding to the charger, and the charging power does not exceed the nominal power of the charger, so that the service life of the charger can be prolonged, and the use safety degree is improved.
Fig. 7 is a flowchart of a charging method provided by an embodiment of the present disclosure, where the charging method is applied to the charging device shown in fig. 3. As shown in fig. 7, the method includes:
in step S11, the identification code of the charger is acquired.
In step S12, the charge instruction information is determined from the identification code.
The charging indication information is used for indicating charging power, and the charging power indicated by the charging indication information does not exceed the nominal power of the charger.
In step S13, the charging instruction information is transmitted to the charger so that the charger performs charging at the charging power indicated by the charging instruction information.
By acquiring the identification code of the charger during charging, the charging indication information corresponding to the acquired identification code can be determined. The charging instruction information is then transmitted to the charger so that the charger can perform charging at the charging power indicated by the charging instruction information. Because the identification code, the charging indication information and the charging power of the charger are mutually corresponding, different chargers can be charged with the charging power corresponding to the charger, and the charging power does not exceed the nominal power of the charger, so that the service life of the charger can be prolonged, and the use safety degree is improved.
The step S11 may acquire the identification code of the charger through the aforementioned acquisition module 12. The terminal and the charger can be connected through a USB interface. The identification code of the charger can be acquired through a first Configuration Channel pin CC1(Configuration Channel) and a second Configuration Channel pin CC2 of the USB interface, or through a data pin D-, or a data pin D +, and charging instruction information can be sent to the charger.
The identification code may be a code set according to at least one of hardware information, software information, a production lot, and a production factory of the charger. Different hardware and software have an influence on the nominal power of the charger, the nominal power of the chargers of different batches in the same manufacturer may be different, and the nominal power of the chargers of the same model in different manufacturers may be different. Setting the identification code based on these pieces of information makes it possible to set the charging power corresponding to the identification code reasonably and shorten the charging time as much as possible on the premise of safety.
Optionally, the identification code may be set according to hardware information, software information, a production batch, and a manufacturer, the identification code may be preset in the charger, and the preset identification codes may be the same for chargers with the same hardware information, software information, production batch, and manufacturer.
Alternatively, in step S12, the charging instruction information corresponding to the identification code of the charger may be determined according to the preset correspondence between the identification code and the charging instruction information.
For example, the charging indication information may be determined by the aforementioned signal determination module 13. The correspondence between the identification code and the charging instruction information may be stored in the aforementioned storage sub-module 131. The charging indication information may be determined by the processing sub-module 132 according to the corresponding relationship between the identification code and the charging indication information. By storing the correspondence between the identification code and the charging instruction information in the storage sub-module 131 in advance, the charging instruction information corresponding to the identification code of the charger can be accurately determined when the terminal is connected to the charger.
The step S12 may include: when the identification code is included in the first set of identification codes, the identification code corresponds to the first charging indication information. When the identification code is contained in the second identification code set, the identification code corresponds to the second charging indication information, and the charging power indicated by the first charging indication information is larger than the charging power indicated by the second charging indication information. Because there may be a plurality of chargers capable of charging the same terminal, the chargers may differ from each other, and it may be possible that a part of the chargers may use a higher charging power to ensure safety when charging the terminal, the identification codes of the part of the chargers may be included in the first identification code set, while another part of the chargers may only use a lower charging power to ensure safety when charging the terminal, and the identification codes of the part of the chargers may be included in the second identification code set.
Further, when the identification code is included in neither the first identification code set nor the second identification code set, the identification code may correspond to third charging indication information, and the charging power indicated by the second charging indication information is greater than the charging power indicated by the third charging indication information. The types of chargers are many, it is difficult to exhaust all chargers connectable to the terminal from among the first identification code set and the second identification code set, and for chargers whose identification codes are included in neither the first identification code set nor the second identification code set, charging can be performed with a lower charging power corresponding to the third charging instruction information to ensure safety. Since the identification codes of the charger are not included in the first identification code set and the second identification code set, it is indicated that the nominal power of the charger is not determined, and the charging power indicated by the third charging indication information can be used for charging, thereby improving the safety.
For example, the charging power indicated by the first charging indication information may be 18W, the charging power indicated by the third charging indication information may be 5W, and the charging power indicated by the second charging indication information is between 5W and 18W, and may be 10W, for example. The charging power indicated by the first charging indication information may be set according to the nominal power of the charger, for example, the charging power indicated by the first charging indication information of the charger may be 85% to 95% of the nominal power of the charger, and the power output by the charger may fluctuate in an actual charging process of the charger, and the charging power is set slightly smaller than the nominal power, so that the power output by the charger may be prevented from exceeding the nominal power when fluctuating, and meanwhile, the charging time may be prevented from being too long due to insufficient use of the charger due to too small charging power setting. In a common terminal, such as a mobile phone, when charging, the nominal power of the connected charger is usually not lower than 5W, and for a charger whose identification codes are not included in the first identification code set 31 and the second identification code set 32, setting the charging power to 5W can ensure safety.
Optionally, the charging method may further include updating a correspondence between the identification code and the charging indication information. With the development of production, new chargers are continuously generated, so that the corresponding relation between the stored identification codes and the charging indication information can be updated, and more chargers can charge the terminal conveniently. For the produced charger, the product defects may be found in the future, and the potential safety hazard can be further reduced by updating the corresponding relation between the stored identification code and the charging indication information.
For example, the corresponding relationship between the stored identification code and the charging indication information may be updated through wired communication or wireless communication. Taking a mobile phone as an example, the mobile phone may establish a connection with the cloud server, and update the correspondence between the identification code stored locally and the charging instruction information in a patch downloading manner.
Optionally, the corresponding relationship between the identification code and the charging indication information may be updated in at least one of the following manners:
at least one identification code is removed from the first set of identification codes or from the second set of identification codes.
At least one of the first set of identifiers is transferred to a second set of identifiers.
At least one of the second set of identifiers is transferred to the first set of identifiers.
At least one identification code included in neither the first set of identification codes nor the second set of identification codes is added to the first set of identification codes or the second set of identification codes.
With the development of production, some existing chargers may not be able to continue to charge the terminal with the charging power indicated by the first charging indication information or the second charging indication information due to the discovery of the existence of a product defect, and the like, and therefore, the identification codes may be extracted from the first identification code set or the second identification code set. Part of the chargers which can be charged by the charging power indicated by the first charging indication information can only be charged by the charging power indicated by the second charging indication information; part of the chargers originally charged by the charging power indicated by the second charging indication information can also be charged by the charging power indicated by the first charging indication information; for the chargers corresponding to the identification codes which are not originally contained in the first identification code set and the second identification code set, after verification, the chargers can be charged by using the charging power indicated by the first charging indication information or the charging power indicated by the second charging indication information, so that the identification codes can be added into the first identification code set and the second identification code set.
Fig. 8 is a flowchart of a charging method provided by the embodiment of the present disclosure, and the charging method is applied to the charging device shown in fig. 6. As shown in fig. 8, the method includes:
in step S21, the charging instruction information transmitted by the terminal is received.
The charging indication information is used for indicating charging power, and the charging indication information is determined according to the acquired identification code after the terminal acquires the identification code of the charger.
In step S22, the terminal is charged with the charging power indicated by the charging instruction information.
Wherein the charging power indicated by the charging indication information does not exceed the nominal power of the charger.
The charging indication information is received from the terminal, the terminal is charged by the charging power indicated by the charging indication information, and the charging indication information is determined according to the obtained identification code after the terminal obtains the identification code of the charger, so that the identification code of the charger, the charging indication information and the charging power indicated by the charging indication information correspond to each other, different chargers can charge the terminal by the charging power corresponding to the charger, and the charging power does not exceed the nominal power of the charger, so that the service life of the charger can be prolonged, and the use safety is improved.
