Description

Charging control method and device, electronic device and computer storage medium

Technical Field

The present disclosure relates to the field of electronic devices, and in particular, to a charging control method and apparatus, an electronic device, and a computer storage medium.

Background

At present, energy supply in consumer electronic equipment generally comes from a lithium ion battery, and the charging speed of the lithium ion battery is increased continuously. The charge duration of the battery was shortened from the previous 3 hours to 90 minutes, even at a rate approaching 30 minutes full charge.

However, as the charging speed increases, the battery reaches a high-capacity, high-voltage state for a short time during the charging process and then remains in this state until the battery is discharged as the electronic device operates. When the battery is in a high-electricity or high-voltage state, the activity of the materials in the battery is very high, side reactions are easily generated, the structure of the cathode material in the lithium battery is damaged by the side reactions or the electrolyte is consumed quickly, and the service life of the lithium battery is further influenced.

The above information disclosed in this background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.

Disclosure of Invention

One object of the present disclosure is to improve the service life of an electronic device battery.

According to an aspect of the present disclosure, there is provided a charge control method including:

acquiring an expected charging time for charging a battery of the electronic equipment to a target electric quantity; wherein the desired charging duration is greater than or equal to a shortest charging duration of the electronic device;

setting a charging parameter according to the expected charging time;

and charging the battery until the electric quantity of the battery reaches the target electric quantity according to the charging parameters within the expected charging time period.

According to another aspect of the present disclosure, there is provided a charge control device including:

a storage unit storing a charging control program;

and the processing unit is used for executing the steps of the charging control method when the charging control program is operated.

According to another aspect of the present disclosure, there is provided a computer storage medium storing a charging control program that, when executed by at least one processor, implements the steps of the charging control method.

According to the technical scheme, the expected charging time is obtained, so that the charging parameter is determined according to the expected charging time, and the battery is charged to the target electric quantity under the charging parameter. Since the desired charge period is generally greater than the shortest charge period of the electronic device, the battery may be allowed to be fully charged over a longer period of time; compared with the quick charging mode, the battery is always in a high-power and high-voltage state after being fully charged for a short time; the technical scheme can reduce the time that the battery is in high electric quantity and high voltage, thereby achieving the balance between meeting the charging requirement of a user and prolonging the service life of the battery.

In addition, due to the arrangement of the expected charging time, the unnecessary times of quick charging are reduced in the whole service life cycle of the battery, and the total time of the battery under high electric quantity and high voltage is effectively reduced, so that the aging speed of the battery is effectively slowed down;

in addition, in the whole charging process, when the expected charging time is longer than the shortest charging time, the charging current is reduced, so that the problem of the attenuation of the service life of the battery caused by the overlarge temperature rise of the battery in the charging process can be favorably solved, and the service life of the battery is prolonged.

In conclusion, the technical scheme of the disclosure can prolong the service life of the battery of the electronic equipment.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

Preferred embodiments of the present disclosure are described in further detail below with reference to the accompanying drawings of the present specification.

The present disclosure proposes an electronic device, which may be a smart terminal, a mobile terminal device, configured with a battery power supply system. The electronic device includes, but is not limited to, a device configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a 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, for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a digital video broadcasting-handheld (DVB-H) network, a satellite network, an AM-FM (amplitude modulation-frequency modulation) broadcast transmitter, and/or another communication terminal. Communication terminals arranged to communicate over a wireless interface may be referred to as "wireless communication terminals", "wireless terminals", and/or "smart terminals". Examples of smart terminals include, but are not limited to, satellite or cellular phones; personal Communication System (PCS) terminals that may combine a cellular radiotelephone with data processing, facsimile and data communication capabilities; personal Digital Assistants (PDAs) that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. In addition, the terminal may further include, but is not limited to, a rechargeable electronic device having a charging function, such as an electronic book reader, a smart wearable device, a mobile power source (e.g., a charger, a travel charger), an electronic cigarette, a wireless mouse, a wireless keyboard, a wireless headset, a bluetooth speaker, and the like.

The following describes a related adapter for charging an electronic device in the related art.

In the related art, the adaptor may operate in a constant voltage mode, and the voltage output therefrom is maintained substantially constant, such as 5V, 9V, 12V, or 20V. The output current can be pulsating direct current (the direction is unchanged, the amplitude is changed along with time), alternating current (both the direction and the amplitude are changed along with time) or constant direct current (both the direction and the amplitude are not changed along with time). The voltage output by the relevant adapter is not suitable for being directly applied to two ends of the battery, but needs to be converted by a conversion circuit in the electronic device to obtain the expected charging voltage and/or charging current of the battery in the electronic device.

The adapter may also operate in a voltage-following manner. The adapter and the electronic equipment to be charged carry out two-way communication, and the adapter feeds back required charging voltage and charging current according to the electronic equipment, so that the voltage and the current output by the adapter are adjusted, the output voltage and the output current can be directly loaded on a battery of the electronic equipment to charge the battery, and the electronic equipment does not need to adjust the charging voltage and the charging current again.

The conversion circuit may control the charging voltage and/or the charging current of the battery during different charging phases. For example, during the constant current charging phase, the inverter circuit may utilize a current feedback loop to cause the magnitude of the current into the battery to meet the magnitude of the first charging current expected by the battery. In the constant voltage charging stage, the conversion circuit may utilize a voltage feedback loop so that the magnitude of the voltage applied across the battery satisfies the magnitude of the charging voltage expected by the battery. During the trickle charge phase, the conversion circuit may utilize a current feedback loop such that the magnitude of the current into the battery meets the magnitude of a second charge current expected by the battery (the second charge current being less than the first charge current).

For example, when the voltage output by the relevant adapter is greater than the expected charging voltage of the battery, the conversion circuit is configured to perform a voltage-down conversion process on the voltage output by the relevant adapter, so that the magnitude of the charging voltage obtained through the voltage-down conversion meets the expected charging voltage of the battery.

Here, the state of the inside of the battery during the rapid charging process is analyzed first.

According to the electrochemical reaction process of the battery in the charging process, Co3+ is continuously oxidized into Co during charging⁴⁺Due to Co⁴⁺The oxidation property of the lithium battery is very high, so that the activity of the lithium battery is very high under the condition of high electric quantity or high voltage, side reactions are easily generated, the structure of a cathode material in the lithium battery is damaged or the consumption of electrolyte is accelerated, the service life of the lithium battery is influenced, and the service life of the lithium battery is reduced.

Secondly, during fast charging, the charging current is large. The temperature rise value of the battery is increased in the charging process due to the large charging current, the activity of the internal material of the battery is also greatly increased in the high-temperature process, the consumption of the electrolyte is accelerated, and the service life of the battery is further influenced.

And thirdly, in the quick charging process, as long as the charging environment (adapter, quick charging protocol) and the like are matched with corresponding quick charging conditions, the battery is automatically and quickly charged at the fastest speed. Therefore, if the battery of an electronic device is charged by the fast charging technique throughout the life cycle, the time during which the battery is at a high voltage increases, the time during which the battery is at a high temperature increases, and the time period during which the battery is aged faster increases.

Embodiments of the disclosed embodiments will be described below.

Fig. 1 shows a flowchart of a charging control method according to an exemplary embodiment of the present disclosure. The method comprises the following steps:

11, acquiring an expected charging time for charging a battery of the electronic equipment to a target electric quantity; wherein the desired charging duration is greater than or equal to a shortest charging duration of the electronic device;

first, the "normal charge mode" and the "quick charge mode" in the charge mode will be described. The normal charging mode refers to the adapter outputting a relatively small current value (typically less than 2.5A) or charging the battery in the device to be charged with a relatively small power (typically less than 15W). It usually takes several hours to fully charge a larger capacity battery (e.g., 3000 ma-hour capacity battery) in the normal charging mode. The fast charging mode means that the adapter is capable of outputting a relatively large current (typically greater than 2.5A, such as 4.5A, 5A or even higher) or charging the battery in the device to be charged with a relatively large power (typically greater than or equal to 15W). Compared with the ordinary charging mode, the adapter has higher charging speed in the quick charging mode, and the charging time required for completely charging the battery with the same capacity can be obviously shortened.

In this embodiment, the shortest charging time of the electronic device refers to a time required for charging the electronic device in the fast charging mode. It is understood that the maximum charging power allowed by the electronic device is specific according to the type of the electronic device or the power output by the adapter for charging the electronic device. In this step, the charging duration, charging power or charging current required to fully charge the battery at the fastest charging speed may be obtained first.

In one embodiment, the desired charge period is set by the target object. The target object may be a user.

In a specific embodiment, the desired charging period is a specific value set directly by the user.

In another specific embodiment, a series of charging duration options are provided by the electronic device for selection by the user. Referring to fig. 2, fig. 2 is a flowchart illustrating an embodiment of step 11 in fig. 1. Specifically, acquiring an expected charging duration for charging a battery of the electronic device to a target electric quantity includes:

1111, outputting a plurality of charging time length information to be selected;

1112, when one of the plurality of charging period information is selected, determining a desired charging period based on the selected charging period information.

In an example, the electronic device has a display unit 44 thereon, and a plurality of pieces of charging period information to be selected may be displayed on the display unit 44. Specifically, a plurality of pieces of charging duration information to be selected may be displayed on a pull-down menu of a main display interface of the electronic device, or a plurality of pieces of charging duration information may be displayed in a "setting" menu of the electronic device.

For convenience of user operation, a charge mode button may be provided on the electronic device, and the button may be a physical button or a virtual button displayed on the display unit 44. When the charge mode button is a virtual button, the charge mode button may be on the same display surface as the plurality of pieces of charging duration information to be selected.

When the adjustable charging mode button is turned on, the plurality of pieces of charging period information to be selected are displayed, or the plurality of pieces of charging period information to be selected are changed to a selectable state. When the adjustable charging mode button is not turned on, it indicates that the user will not select any charging period information. Alternatively, the battery may be rapidly charged by default in a fast charge mode to fully charge the battery in a minimum amount of time.

In another embodiment, the setting mode of the charging duration information may also be that a plurality of keys are provided on the electronic device, and each key corresponds to one piece of charging duration information. The user presses the corresponding key to select the corresponding charging duration information.

The charging period information may be a specific charging period, for example, 35 minutes is required for charging the battery in a fast charge mode from 0 to 100%. The set plurality of charging periods may be 35 minutes, 50 minutes, 60 minutes, 90 minutes, 180 minutes, 240 minutes, etc. for selection by the user.

The charging period information may be a charging end time based on the current time. Specifically, displaying a plurality of charging duration information to be selected on the electronic device includes:

displaying a plurality of charging end moments to be selected on the electronic equipment;

when one piece of charging duration information in the plurality of charging duration information is selected, determining the expected charging duration according to the selected charging duration information, including:

when one charging end time in the plurality of charging end times is selected, acquiring the current time;

and determining the expected charging time length according to the time length between the current time and the selected charging ending time.

Based on the above example, the current time is 12:00, and the plurality of set charging end times may be 12:35, 12:50, 13:00, 13:30, 15:00, 16:00, and the like for the user to select.

The user can select a certain charging time length information according to the situation. When the user does not need to charge the battery to a full charge state in a short time, a longer desired charging period may be selected. When the user needs to charge the battery to a full charge state in a short time, the shortest time period may be selected as the desired charging time period.

However, if the adjustable charging mode button is turned on, but the user does not select the desired charging time period information at a later time, the default charging time period may be set as the desired charging time period, specifically, the desired charging time period for charging the battery of the electronic device to the target electric quantity is obtained, further including:

1113, when the selected duration of the unacquired charging duration information reaches a first preset duration, taking the shortest charging duration of the electronic device as the expected charging duration.

The first preset time period may be 15 seconds, 30 seconds, or the like, and is not limited herein. In this embodiment, when the user does not select the desired charging period information within the first preset period, the battery may be directly charged in the fast charge mode.

In an embodiment, in order to facilitate the user to recognize each charging duration information, the charging durations corresponding to the charging duration information may be gradually increased, and the duration difference between the charging durations corresponding to two adjacent charging duration information may be gradually increased. For example, the plurality of charging durations are arranged in a row, the charging duration corresponding to the charging duration information near the top of the screen is the shortest, and the charging duration corresponding to the charging duration information near the bottom of the screen is the longest.

Further, the target charge amount may be set to a full charge amount by default, i.e., charged from the current charge amount to 100%. Because the corresponding full-charge voltage of the battery is higher when the battery is full of electricity, a user can set the target electricity to be lower than the full of electricity, so that the average voltage level of the battery voltage is reduced, and the service life of the battery is prolonged.

Specifically, obtaining an expected charging duration for charging a battery of the electronic device to a target electric quantity further includes:

outputting a plurality of pieces of battery electric quantity information to be selected;

when one piece of battery electric quantity information in the plurality of pieces of battery electric quantity information is selected, determining the target electric quantity according to the selected battery electric quantity information.

In this embodiment, the plurality of battery level information to be selected may be displayed on a display screen of the electronic device. Optional battery charge information is provided to the user. In one embodiment, the battery level information may be displayed as a percentage of the full battery level. For example 80%, representing 80% of the charge to full charge; and 60% represents 60% of the full charge.

Optionally, the battery power information may be displayed simultaneously with the plurality of charging duration information. When the user selects a plurality of pieces of charging period information, the target amount of electricity can be set.

In another embodiment regarding obtaining the desired charging period, the setting may be made by the electronic device itself according to the current usage scenario without user operation. Such as a break scene, a sports scene, etc. Referring to fig. 3, fig. 3 is a flowchart illustrating another embodiment of step 11 in fig. 1. In a specific embodiment, obtaining a desired charging duration for charging a battery of an electronic device to a target charge amount includes:

1121, acquiring a current use scene of the electronic device;

and 1122, setting a desired charging time period for charging the battery to the target charge amount according to the usage scenario of the electronic device.

The work and rest of the user can be monitored through the use condition of the user on the electronic equipment and the alarm clock setting condition, and the current use scene is determined by combining the current time.

Specifically, according to a usage scenario of the electronic device, setting a desired charging duration for charging the battery to the target electric quantity includes:

when the current use scene is a night sleep scene, acquiring a set time which is set by an alarm clock on the electronic equipment and is closest to the current time;

and calculating the time length between the set time and the current time, wherein the time length is used as the expected charging time length.

For example, during the sleeping process of the user at night, the alarm clock for getting up the next day set by the user is assumed to be 7:00, and the time for starting to insert the charger is 23:00 at night, the system recognizes that the user does not need to use the mobile phone between 23:00 at night and 7:00 at the next day. Therefore, the corresponding charging speed can be calculated according to the time range, the time period is 8h, so the charging multiplying power is 1/8C, the battery capacity is 4000mAh, the charging is started when the electric quantity is 10%, and the charging current is 450mA when the battery is required to be fully charged and the capacity is 3600mAh, so the battery can be fully charged with constant current and constant voltage by using the current of 450mA just before the user gets up.

In this embodiment, with the user sleeping at night, the electronic device is not required to be used for a short time, so that the desired charging period that matches the user sleeping period can be set with the software program. Until the user wakes up, just to fully charge the battery. Because the night sleep time is longer, the battery can be charged at a slower charging speed, the charging time is prolonged, and further, compared with the quick charging, the time that the battery is in a full-charge and high-voltage state is shortened, so that the battery is effectively protected, and the service life of the battery is prolonged. Compared with the quick charging mode, the battery can be charged to a full state within tens of minutes, and then the battery is kept in the full state all the time, so that the battery is in a high-power and high-voltage state for a long time, and the service life of the battery is influenced.

With continuing reference to fig. 1, the method further includes:

12, setting charging parameters according to the expected charging time;

and 13, charging the battery until the battery capacity reaches the target capacity according to the charging parameters within the expected charging time period.

The charging parameters may include charging power, charging voltage, charging current, charging duration, charging start time, charging end time, etc. When the electronic equipment is connected with the adapter and starts to be charged, the electronic equipment and the adapter perform handshake matching, a matching instruction is sent to the adapter through a control system of the electronic equipment, and the adapter sends an agreement signal when the electronic equipment and the adapter are matched. The adapter can be a common adapter or a PD adapter supporting a PD charging protocol.

In an embodiment, the setting a charging parameter according to the expected charging duration includes:

acquiring a corresponding relation between preset charging duration information and charging parameters;

determining a charging parameter corresponding to the expected charging time according to the corresponding relation between the preset charging time information and the charging parameter;

and setting the determined charging parameters as the charging parameters for charging the battery.

The corresponding relationship between the preset charging duration information and the charging parameters can be measured in a laboratory before the battery leaves a factory, and then the corresponding relationship is prestored in the electronic equipment. After the expected charging time period is determined, the charging parameters of the corresponding battery can be found through searching.

In the above embodiment, in the scheme of determining the expected charging time period according to the selected charging time period information by outputting the plurality of pieces of charging time period information to be selected, it may be further set that each piece of charging time period information corresponds to a specific charging parameter, and when a user selects a certain piece of charging time period information, the system may automatically call the corresponding charging parameter for charging the battery of the electronic device.

Referring to fig. 4, fig. 4 is a flowchart illustrating an embodiment of step 12 and step 13 in fig. 1. In one embodiment, the charging parameter includes a desired charging current, and setting the charging parameter according to a desired charging duration includes:

121, acquiring the current residual capacity of the battery;

122, calculating a difference value between the target electric quantity and the current residual electric quantity, wherein the difference value is a first difference value;

123, determining an expected charging current according to the first difference value and the expected charging time period;

charging the battery to a target charge level within the desired charging duration using the charging parameters, including:

and 131, charging the battery to the target charge level based on the desired charging current from the beginning of the desired charging period.

For example, from 0% full initial charge to 100% target charge, a battery capacity of 4000mAh, and a user selected time from 12:00 to 13:00 full, the desired charging current required is calculated to be 4A. In this example, the calculated desired charging current may be understood as an average charging current, and when charging in a constant current charging mode or VOOC charging mode, the charging current for each charging phase may be configured according to the desired charging current.

When the charging mode is a constant-current constant-voltage charging mode, the charging process of the battery comprises a constant-current charging stage and a constant-voltage charging stage; charging the battery to the battery charge level to the target charge level based on the desired charge current from the beginning of a desired charge period, comprising:

in the constant current charging stage, charging the electronic equipment by using a first charging current matched with the expected charging current until the voltage of the battery reaches a first cut-off voltage, wherein the first charging current is greater than the expected charging current;

in the constant voltage charging stage, the battery is charged with a charging voltage matching the first cutoff voltage.

Continuing with the above example, the desired charging current is calculated to be 4A, where the constant voltage charging phase is designed to eliminate the effect of the floating voltage in the battery. If the cut-off voltage of the battery is 4.4V, the battery is charged at a constant voltage of 4.4V until the current is reduced to a certain cut-off current value, and the charging is finished. Therefore, in order to reserve a certain time for the constant voltage charging phase, in the constant current charging phase, it may be slightly increased based on the calculated expected charging current as the actual charging current, for example, setting the actual charging current to 4.5A to ensure that the battery is fully charged within the expected time.

In the above embodiment, the charging process is continued for the entire desired charging period from almost the beginning of the connection with the charger. In another embodiment, the charging period may be set within a desired charging period, and the battery may be stopped from charging for other periods of the charging period within the desired charging period.

Specifically, referring to fig. 5, fig. 5 is a schematic diagram illustrating a corresponding relationship between a charging time period and a desired time period according to an embodiment. In one embodiment, the charging period is within a desired charging period and the duration of the charging period is less than the desired charging period, 12, setting the charging parameter according to the desired charging period includes:

setting a duration of a charging period, and a desired charging current within the desired charging period, according to the desired charging period;

charging the battery to a target charge level within the desired charging duration using the charging parameters, comprising:

after entering the desired charging period, and during the charging period, the battery is charged to a target charge based on the desired charging current.

It is understood that the battery is in a charged state only during the charging period throughout the desired charging period, and thus when calculating the desired charging current, the desired charging current needs to be calculated based on the period of the charging period and the amount of charge that needs to be charged. According to different charging modes, the charging mode can be divided into constant-current constant-voltage charging mode, segmented constant-current charging mode, VOOC charging mode and the like. It is understood that, according to the calculated expected charging current, the charging current or the charging power corresponding to each sub-phase can be set corresponding to the charging mode.

In one example, the battery may be charged in a fast charge mode during a charging period. The length of the charging period at this time corresponds to the shortest charging length. For example 35 minutes. The start time of the desired charging period is approximately the time of successful connection with the charger. The charging period of 35 minutes is located in the latter section of the later charging period of the desired charging period. In this latter phase, the midpoint of the charging period is later than the desired charging period.

For example, if the desired charging period is 7 hours, the charging period may be entered 25 minutes after the desired charging period has been performed for 6 hours. The battery is fully charged within 35 minutes in a fast charge mode during the charging period.

In this embodiment, the battery is not charged early in the desired charge period, thereby placing the battery in a low charge, low voltage state, thereby reducing the time the battery is in a high charge, high voltage state. And charging the battery at the later section of the expected charging time period so as to fully charge the battery before the expected charging time period is finished, thereby ensuring the use of the user. Therefore, the high-power time of the battery is shortened, the attenuation of the service life of the battery caused by the excessive temperature rise during quick charging is reduced, and the service life of the battery of the electronic equipment is prolonged.

Referring to fig. 6, fig. 6 is a schematic diagram illustrating a corresponding relationship between a charging time period and a desired time period according to another embodiment. In another embodiment, the desired charging period includes a plurality of charging periods that are sequentially intermittent; namely, the battery is charged for a period of time, and the charging is stopped for a period of time, and the steps are alternately carried out. Specifically, 12, according to the expected charging duration, setting charging parameters, including:

setting the duration of each charging time period, the interval duration of two adjacent charging time periods and the expected charging current corresponding to each charging time period according to the expected charging time period;

charging the battery to a target charge level according to the charging parameters for a desired charging duration, comprising:

when entering a charging time period, charging the battery by using the charging parameters corresponding to the charging time period;

stopping charging the battery for a duration between the charging time period and a next charging time period;

and entering the next charging time period, and charging the battery by the charging parameter corresponding to the next charging time period.

In this embodiment, the duration of each charging period may or may not be equal. Optionally, the duration of each charging period is equal, and the interval duration between two adjacent charging periods is also equal.

In this embodiment, a corresponding charging mode may be set for each period, for example, a constant current charging mode is set in one charging period, and a constant voltage charging mode is set in another charging period. These charging periods may be sequentially performed based on the set charging mode. For example, the set charging mode is a constant-current constant-voltage charging mode, and there are three charging time periods, so that the whole process of the constant-current constant-voltage charging mode can be divided into three segments, which are respectively and sequentially performed in the three charging time periods.

In the present embodiment, since a plurality of charging periods are intermittently performed in sequence, intermittent charging can be realized, and therefore the battery charge amount increases as time goes on throughout the desired charging period, and therefore a certain amount of charge in the battery can be secured even if the user stops charging halfway. More importantly, in the whole expected charging time period, the electric quantity of the battery cannot be increased to the full electric quantity in a short time and is kept at the full electric quantity, so that the duration of the battery at high electric quantity and high voltage is reduced, the attenuation of the service life of the battery caused by the excessive quick charging temperature rise is reduced, and the service life of the battery of the mobile terminal is prolonged.

According to the technical scheme, the expected charging time is obtained, so that the charging parameter is determined according to the expected charging time, and the battery is charged to the target electric quantity under the charging parameter.
