Background
Intelligent electronic devices such as smartphones and PADs are increasingly popular with consumers, but these electronic devices consume large amounts of power and require frequent charging. To cope with this challenge, the industry has sequentially proposed a high-voltage fast charge scheme and a low-voltage high-current fast charge scheme based on the conventional charge scheme. Both charging schemes require a large current to charge the battery in the electronic device.
Although the rapid charging process does not have an excessive impact on the life of the battery through the design of the battery development scheme and the charge management scheme. But high current charging still has some damage to the battery. For example, a fast charge of a battery may result in a battery that is in a low voltage phase for a relatively short period of time and in a high voltage phase for a relatively long period of time; co during charging according to electrochemical reaction process of battery during charging 3+ Continuously oxidized to Co 4+ . And because of Co 4+ The oxidation property of the lithium ion battery is very high, the activity of the battery is very high under the state of high electric quantity or high voltage, side reactions are easy to generate, the cathode material structure in the lithium battery is damaged or the electrolyte consumption is accelerated, and the service life of the lithium battery is influenced. In addition, at the time of quick charge, the temperature of the battery increases during charging because of an increase in current. The activity of the internal materials of the battery can be greatly increased in the high-temperature process, and the consumption of electrolyte is greatly increasedWill accelerate.
Currently, when an adapter matches the fast capabilities of an electronic device, the adapter will directly fast charge the electronic device, although the current user does not have the fast charge requirements.

When a user does not need to perform a quick charge (e.g., night charge), a mechanism is needed to provide a proper charge voltage and/or charge current to the battery depending on whether the user has a quick charge. The fast charge mode will be described hereinafter.
The charging method provided by the embodiment of the present disclosure is specifically described below.
Fig. 1 is a flowchart illustrating a charging method according to an exemplary embodiment. The charging method can be applied to the electronic equipment.
The electronic device may be, for example, a terminal or a communication terminal including, but not limited to, means arranged to receive/transmit communication signals via a wireline connection, such as via a public-switched telephone network (public switched telephone network, PSTN), a digital subscriber line (digital subscriber line, DSL), a digital cable, a direct cable connection, and/or another data connection/network and/or via a wireless interface, for example, to a cellular network, a wireless local area network (wireless local area network, WLAN), a digital television network such as a digital video broadcasting-handheld (digital video broadcasting handheld, DVB-H) network, a satellite network, an amplitude-frequency modulation (amplitude modulation-frequency modulation, AM-FM) broadcast transmitter, and/or another communication terminal. A communication terminal configured to communicate via a wireless interface may be referred to as a "wireless communication terminal," wireless terminal, "and/or" mobile terminal. Examples of mobile terminals include, but are not limited to, satellites or cellular telephones; a personal communications system (personal communication system, PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; personal digital assistants (Personal Digital Assistant, PDA) that may include a radiotelephone, pager, internet/intranet access, web browser, organizer, calendar, and/or a global positioning system (global positioning system, GPS) receiver; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. In addition, the terminal can further comprise, but is not limited to, chargeable electronic devices with charging functions, such as electronic book readers, intelligent wearable devices, mobile power sources (such as charger, travel charger), electronic cigarettes, wireless mice, wireless keyboards, wireless headphones, bluetooth sound boxes and the like. In addition, the electronic device may be an electric vehicle using a lithium ion battery as an energy source.
Referring to fig. 1, a charge control method 10 includes:
in step S102, desired charging information for the electronic device is acquired.
In some embodiments, the desired charging information may be used to indicate whether charging is occurring at the fastest speed. This information may be set by a user through a user interface, for example. If the user wishes to charge at the fastest speed, then the desired charge information is set to charge at the fastest speed. If the user does not wish to charge at the fastest speed, the desired charge information is set so as not to charge at the fastest speed. It will be appreciated that this information may also be used to indicate whether the battery is full in the shortest time. In addition, this information may also be used to indicate different speed steps (or full time steps), such as fastest speed, medium speed (e.g., 75% of fastest speed, etc.), slow speed (e.g., 50% of fastest speed, etc.), etc. That is, the desired charging information is a certain speed gear (or full time gear) selected by the user.
In step S104, desired charging information is transmitted to the power supply device.
In some embodiments, in addition to transmitting the desired charging information to the power supply apparatus, battery information may be acquired and transmitted to the power supply apparatus.
The battery information of the electronic device may be stored in the electronic device in advance. The battery information may include, for example: charging strategy information (such as constant-current constant-voltage charging mode, step charging mode, pulse charging mode, etc.), cut-off voltage of the battery, time for the fastest charging of the battery, maximum charging power or maximum charging current, etc.
When a user connects the power supply device with the electronic equipment to charge the electronic equipment, the electronic equipment firstly identifies the type of the power supply device by communicating with the power supply device; and negotiates with the power supply device a charging mode to be adopted after negotiation with the power supply device according to the type of the power supply device. And transmits the acquired battery information and the desired charging information to the power supply device.
The charging modes may include, for example: a "normal charge mode" and a "quick charge mode".
The normal charging mode refers to the adapter outputting a relatively small current value (typically less than 2.5A) or charging a battery in a device to be charged with relatively small power (typically less than 15W). In the normal charging mode, it is often necessary to take several hours to fully charge a larger capacity battery (e.g., a 3000 milliamp capacity battery).
The fast charge mode refers to the adapter being able to output a relatively large current (typically greater than 2.5A, such as 4.5A,5A or even higher) or to charge a battery in a device to be charged with a relatively large power (typically 15W or more).
Compared with the common charging mode, the charging speed of the adapter in the quick charging mode is higher, and the charging time required for completely filling the batteries with the same capacity can be obviously shortened.
The power supply device may be a general type adapter, for example, a power adapter having a maximum output power of 10W (5V/2A) and charging the device to be charged in the above general charging mode; alternatively, the power supply device may be a first type of fast charging adapter, for example, a 20W (5V/4A) high power adapter, and the apparatus to be charged is charged in the fast charging mode; still alternatively, the power supply device may be a second type of quick charge adapter, for example, a high power adapter having a maximum output power of 50W (10V/5A), and the device to be charged may be charged in the above-described quick charge mode.
After receiving the desired charging information, the power supply device determines a suitable charging voltage and/or charging current to be output to the electronic device within the range of the fastest charging time, the cut-off voltage, the maximum charging current, the maximum charging power and the like of the battery based on the desired charging strategy and the battery information.
In step S106, the battery in the electronic device is controlled to be charged with the charging current and/or the charging voltage output by the power supply device and matching the desired charging information.
When the power supply device determines a charging current and/or a charging voltage that match the desired charging information and outputs the charging current and/or the charging voltage to the electronic device, the electronic device is charged with the charging circuit and/or the charging voltage.
According to the charging method provided by the embodiment of the disclosure, the electronic equipment sends the acquired expected charging information to the power supply device, and charges with the charging current and/or the charging voltage which are output by the power supply device and matched with the expected charging information. The charging method enables the electronic equipment to be charged according to the charging mode expected by the user, and only the electronic equipment can be charged rapidly without being in line with the rapid charging condition, so that the service life of the battery is prolonged to a certain extent.
It should be clearly understood that this disclosure describes how to make and use particular examples, but the principles of this disclosure are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
Fig. 2 is a flow chart illustrating another charging method according to an exemplary embodiment. Unlike the charging method 10 shown in fig. 1, the charging method 20 shown in fig. 2 further includes, prior to step S102 shown in fig. 1:
in step S202, battery information of the battery is acquired.
As described above, the battery information of the electronic device may be stored in the electronic device in advance. The battery information may include, for example: charging strategy information (such as constant-current constant-voltage charging mode, step charging mode, pulse charging mode, etc.), cut-off voltage of the battery, time for the fastest charging of the battery, maximum charging power or maximum charging current, etc.
In step S204, the battery information is transmitted to the power supply device.
As described above, when a user connects the power supply device with the electronic apparatus to charge the electronic apparatus, the electronic apparatus first identifies the type of the power supply device by communicating with the power supply device; and negotiates with the power supply device a charging mode to be adopted after negotiation with the power supply device according to the type of the power supply device. And transmits the acquired battery information to the power supply device.
In step S206, a plurality of pieces of charging range information transmitted from the power supply device are received.
After receiving the battery information, the power supply device can design a plurality of charging gear information within the range of the fastest charging time, the cut-off voltage, the maximum charging current, the maximum charging power and the like according to different charging strategies reflected by the battery information. Different charging range information may correspond to different battery fill times. For example, it may include: battery charge time, charging current, charging power. Such as designing multiple battery fill times, or multiple maximum charge currents, or multiple maximum charge powers, etc. And transmitting the plurality of charging range information to the electronic device.
In addition, the aging speed of the battery is increased due to the high voltage. Thus, if the user's demand for power is not particularly great at some times, the gear information may also be set to indicate the degree of charging power at different charging powers or different charging times or different charging currents, such as to stop charging at a certain power, i.e. to stop charging at a certain power, such as 80% of the power. This reduces the voltage at which the battery is placed and thus reduces the effect of high voltage on battery aging.
In step S208, a plurality of charging range information is provided to the user for selection by the user.
The plurality of charging range information may be displayed to a user for selection through a user interface, such as through a display module in the electronic device. Alternatively, a plurality of charging range information may be played to the user through the audio module. Alternatively, the plurality of charging range information may be displayed and played to the user at the same time, so as to prompt the user to pay attention.
In addition, step S102 further includes: based on the user's selection, desired charging information is obtained.
The desired charging information is one of a plurality of charging range information.
For example, the user selects one of the plurality of charging range information through the user interface displayed by the display module, and transmits the selected charging range information as desired charging information to the power supply device, so as to request the power supply device to output a charging current and/or a charging voltage that match the desired charging information.
Alternatively, the electronic device may recognize recognition of the plurality of pieces of charging range information by voice by the user through voice recognition, for example.
In some embodiments, when it is detected that the charging range information selected by the user is not acquired within a preset time, for example, the preset default charging range information may be used as the desired charging information. In addition, in the preset time, before the charging range information selected by the user is not acquired, the power supply device is requested to output the charging voltage and/or the charging current matched with the default charging range information. The default charging range information may be charging range information corresponding to the battery being charged in the shortest time, for example.
In some embodiments, the battery is stopped from being charged until the charging range information selected by the user is not acquired within the preset time.
According to the charging method provided by the embodiment of the disclosure, battery information is further sent to the power supply device, and a plurality of charging gear information sent by the power supply device is received for selection by a user; after the charging gear information selected by the user is acquired, the charging gear information is fed back to the power supply device so as to request the power supply device to output charging current and/or charging voltage matched with the charging gear. The method can reduce unnecessary quick charge times, and prolongs the service life of the battery to a certain extent.
Fig. 3 is a flowchart illustrating yet another charging method according to an exemplary embodiment. The charging method 30 shown in fig. 3 may be applied to, for example, a power supply device.
Referring to fig. 3, the charging method 30 includes:
in step S302, desired charging information transmitted by the electronic device is received.
As described above, in some embodiments, the desired charging information may be used to indicate whether charging is occurring at the fastest speed. This information may be set by a user through a user interface, for example. If the user wishes to charge at the fastest speed, then the desired charge information is set to charge at the fastest speed. If the user does not wish to charge at the fastest speed, the desired charge information is set so as not to charge at the fastest speed. It will be appreciated that this information may also be used to indicate whether the battery is full in the shortest time. In addition, this information may also be used to indicate different speed steps (or full time steps), such as fastest speed, medium speed (e.g., 75% of fastest speed, etc.), slow speed (e.g., 50% of fastest speed, etc.), etc. That is, the desired charging information is a certain speed gear (or full time gear) selected by the user.
In step S304, a charging current and/or a charging voltage, which are/is output to the electronic device and match the desired charging information, is determined according to the desired charging information.
After receiving the expected charging information, the power supply device determines an appropriate charging voltage and/or charging current output to the electronic device within the range of the fastest charging time, cut-off voltage, maximum charging current, maximum charging power and the like of the battery based on the expected charging strategy and battery information acquired from the electronic device.
For example, if the user desires to charge at the fastest charge speed, the maximum charge power may be output to the user. If the user does not desire to charge at the fastest charge rate, then the appropriate charge voltage and/or charge current to output to the electronic device may be determined within the fastest charge time, cutoff voltage, maximum charge current, maximum charge power, etc. of the battery. Alternatively, if the desired charging information is the above-described certain speed gear (or full-time gear), the charging current and/or the charging voltage may be determined based on the gear and the battery information.
It should be noted that, for different rapid charging protocols, the current peak duration during a typical charging process may not be too long, for example, when charging at 40W power, the charging time at 8A current may be only a few minutes. Therefore, when determining the charging current and/or the charging voltage according to the speed gear or the full time gear desired by the user, it is also necessary to perform matching according to time, i.e., whether the time due to the change in the charging power can be matched with the determined charging current and/or charging voltage.
In step S306, the charging current and/or the charging voltage is output to the electronic device.
According to the charging method provided by the embodiment of the disclosure, the power supply device can determine the matched charging current and/or charging voltage according to the received charging mode expected by the user, so that the electronic equipment can be charged according to the charging mode expected by the user, and only the quick charging can be performed under the condition of meeting the quick charging condition, and the service life of the battery is prolonged to a certain extent.
Fig. 4 is a flowchart illustrating yet another charging method according to an exemplary embodiment. Unlike the charging method 30 shown in fig. 3, the charging method 40 shown in fig. 4 further includes, prior to step S302 shown in fig. 3:
in step S402, battery information of a battery in the electronic information is received.
As described above, the battery information of the electronic device may be stored in the electronic device in advance. The battery information may include, for example: charging strategy information (such as constant-current constant-voltage charging mode, step charging mode, pulse charging mode, etc.), cut-off voltage of the battery, time for the fastest charging of the battery, maximum charging power or maximum charging current, etc.
When a user connects the power supply device with the electronic equipment to charge the electronic equipment, the electronic equipment firstly identifies the type of the power supply device by communicating with the power supply device; and negotiates with the power supply device a charging mode to be adopted after negotiation with the power supply device according to the type of the power supply device. And transmits the acquired battery information to the power supply device.
In step S404, a plurality of pieces of charging range information are determined from the battery information.
After receiving the battery information, the power supply device can design a plurality of charging gear information within the range of the fastest charging time, the cut-off voltage, the maximum charging current, the maximum charging power and the like according to different charging strategies reflected by the battery information. Different charging range information may correspond to different battery fill times. For example, it may include: battery charge time, charging current, charging power. Such as designing multiple battery fill times, or multiple maximum charge currents, or multiple maximum charge powers, etc. And transmitting the plurality of charging range information to the electronic device.
In addition, the aging speed of the battery is increased due to the high voltage. Thus, if the user's demand for power is not particularly great at some times, the gear information may also be set to indicate the degree of charging power at different charging powers or different charging times or different charging currents, such as to stop charging at a certain power, i.e. to stop charging at a certain power, such as 80% of the power. This reduces the voltage at which the battery is placed and thus reduces the effect of high voltage on battery aging.
It should be noted that, for different rapid charging protocols, the current peak duration during a typical charging process may not be too long, for example, when charging at 40W power, the charging time at 8A current may be only a few minutes. Therefore, when determining a plurality of pieces of charging range information, it is also necessary to perform matching according to time, i.e., whether or not time due to a change in charging power can be matched with the charging current and/or the charging voltage corresponding to each range.
Wherein, different charging gear information corresponds to different battery full time. The charging range information includes at least one of the following information: battery charge time, charging current, charging power. . Such as designing multiple battery fill times, or multiple maximum charge currents, or multiple maximum charge powers, etc.
In step S406, a plurality of charging range information is transmitted to the electronic device.
The electronic device provides the plurality of charging range information to the user for selection by the user. And transmitting the selected charging gear information to a power supply device, wherein the expected charging information is one of the selected charging gear information.
According to the charging method provided by the embodiment of the disclosure, the power supply device further determines a plurality of charging gear information according to the battery information sent by the electronic equipment, and sends the charging gear information to the electronic equipment for selection by a user; and outputting a charging current and/or a charging voltage requested by the electronic device and matched with the charging gear selected by the user to the electronic device. The method can reduce unnecessary quick charge times, and prolongs the service life of the battery to a certain extent.
