Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.

Along with the diversification of the use scene of electronic equipment, many users like to use electronic equipment while charging, and after such use mode causes the battery of electronic equipment to be fully charged, be in the high temperature high pressure state for a long time to lead to the life-span of battery to shorten, appear battery swell, problem such as inflation.

In the related art, aiming at the condition that repeated charging occurs for a plurality of times in a single charging process, the service life of the battery is optimized by reducing the repeated charging times, and in this way, the battery still can be under a higher voltage for a long time due to higher electric quantity during repeated charging. In another related art, when a user starts a night charging mode, the charging capacity of the battery is limited, so that the battery cannot be charged to a full charge, and the method is single, and has limitations without considering an actual charging scene.

For example, referring to the schematic diagram of battery capacity loss at the same ambient temperature and different electric quantities shown in fig. 1, at an ambient temperature of 45 degrees, the electric quantities of two identical batteries are respectively maintained at 50% and 100%, the initial capacities of the two batteries are 100%, the capacity loss of the battery is 1% after the battery is maintained at 50% of the electric quantity for 30 days, the capacity loss of the battery is 5% after the battery is maintained at 100% of the electric quantity for 30 days, the capacity loss of the battery is 1.8% after the battery is maintained at 50% of the electric quantity for 60 days, and the capacity loss of the battery is 9% after the battery is maintained at 100% of the electric quantity for 60 days, as can be seen from fig. 1, the higher the electric quantity of the battery is at the same ambient temperature, the larger the battery capacity loss is. Accordingly, in the embodiments of the present disclosure, the full charge amount of the battery is adjusted according to the relationship between the temperature and the full charge amount of the battery to reduce the loss of the battery capacity.

The battery charging method provided by the embodiment of the disclosure can be applied to various scenes.

For example, the method is applied to a driving navigation scene, a plurality of users can start navigation during driving, and because the navigation is very power-consuming, the users can select to navigate while charging, in this case, the mobile phone can always maintain the state of the navigation while charging, so that the battery of the mobile phone is in a high-temperature and high-pressure state for a long time, and the service life of the battery is influenced.

For example, when the method is applied to a game scene, the power consumption of the game is high, and a plurality of users play the game while charging the game, under the condition that the battery of the mobile phone is always kept at high temperature and high pressure after being full, the service life of the battery is influenced.

Before describing the battery charging mode provided in the embodiments of the present disclosure, a description will be given of a battery charging system, referring to a schematic diagram of the battery charging system shown in fig. 2, the electronic device is connected to a charging device (Adapter), the charging device provides Input Current for the electronic device, and then, through a power supply controller in the electronic device, a part of the Input power is provided as system power to a system of the electronic device, that is, sys Current is provided to the system, another part of the Input power is provided to the battery, that is, charge Current is provided to the battery. When the electronic device is fully charged (the full Charge is 100% by default), the battery charging path is closed, at this time, the Charge Current is 0, the Input Current is all supplied to the system, and when the Input Current is closed, the power consumption of the system is supplied by the battery, and the Charge of the battery is reduced.

Fig. 3 is a flowchart illustrating a method of battery charging, performed by an electronic device, see fig. 3, according to an exemplary embodiment, the method comprising the steps of:

step S301 obtains a first full charge amount of a battery of the electronic device, the first full charge amount being a current full charge amount of the battery.

The electronic equipment is connected with the charging equipment, and the charging equipment is a charger.

In the embodiment of the disclosure, under the condition that the electronic device is connected with the charging device, that is, under the condition that the electronic device is continuously charged, the current full charge amount of the electronic device is obtained, that is, the first full charge amount is obtained, and the full charge amount of the battery is the maximum chargeable electric quantity of the battery in the charging process. For example, the first full charge is 100%, 99%, 98%, or other charge.

Step S302, based on the first correspondence, a second full charge corresponding to the current temperature of the battery is obtained.

The first correspondence is a correspondence between a temperature of the battery and a full charge amount, and the second full charge amount is a full charge amount more suitable for a current temperature of the battery, and may be higher than or lower than or the same as the first full charge amount. For a certain temperature of the battery, when the full charge of the battery is maintained at the full charge corresponding to the temperature, the battery can be prevented from being in a high state of charge all the time.

Step S303, the full charge of the battery is modified from the first full charge to the second full charge.

In the embodiment of the disclosure, during the charging process, the temperature of the battery may be changed along with the ambient temperature, the charging duration, and the use of the electronic device by the user, in which case, the first full charge may not be the most suitable full charge for the current temperature of the battery, and in order to increase the service life of the battery, the full charge of the battery is modified from the first full charge to the second full charge.

Step S304, charging is performed based on the second full charge amount.

Charging based on the second full charge amount means that the charging process of the electronic device by the charging device is adjusted so that the full charge amount of the battery is maintained at the second full charge amount.

The implementation process of steps S301 to S304 may be performed repeatedly, where the first full charge amount is a preset amount of electricity when the process is performed for the first time, and from the second time, the first full charge amount is the second full charge amount obtained last time, and the process of obtaining the first full charge amount is described below:

referring to fig. 4, fig. 4 is a flowchart illustrating a process of acquiring a full charge according to an exemplary embodiment, which is performed by an electronic device, comprising the steps of:

In step S401, when the electric quantity of the battery reaches the preset electric quantity in the charging process, the duration of the electric quantity of the battery in the preset electric quantity is detected.

The preset power is a preset chargeable maximum power, for example, the preset power is 100%, 99% or other power. When the electric quantity of the battery reaches the preset electric quantity, the current charged maximum electric quantity is indicated, the electric quantity of the battery is not increased under the condition of continuous charging, the duration of the electric quantity of the battery at the preset electric quantity is detected at the moment, and the longer the duration is, the longer the duration is indicated under the high-temperature high-electric quantity.

In some embodiments, when the electric quantity of the battery reaches the preset electric quantity in the charging process and the charging state is the full charging state, the duration that the electric quantity of the battery is continuous with the preset electric quantity is detected. The full charge state refers to that the battery capacity is full. In the embodiment of the disclosure, considering that the electric quantity of the battery displayed by the electronic device can be set manually, when the electric quantity of the battery reaches the preset electric quantity, the actual electric quantity of the battery may not reach the preset electric quantity, so that the charging state of the battery needs to be judged, when the charging state is in a full charging state, the battery capacity is indicated to be full, and at the moment, the electric quantity of the battery also reaches the preset electric quantity. For example, the FULL charge state may be denoted FULL.

In some embodiments, when the electric quantity of the battery reaches the preset electric quantity in the charging process, a timer is started, and the timing duration of the timer is a first preset duration. The first preset duration is a preset duration, for example, the first preset duration is 10 minutes, 20 minutes or other durations.

Step S402, when the time length reaches a first preset time length, the preset electric quantity is determined to be a first full charge quantity.

When the duration reaches the first preset duration, the electric quantity of the battery is indicated to be maintained for a period of time at the preset electric quantity, the electric quantity of the battery can not be increased any more, and the preset electric quantity is determined to be the first full charge.

In some embodiments, the timer times out, determining the preset amount of power as the first full charge.

It should be noted that, in other embodiments, the duration does not reach the first preset duration, that is, the timer does not timeout, it is determined whether the charging device is disconnected from the electronic device, if the charging device is not disconnected, the duration that the electric quantity of the battery is continuously detected in the preset electric quantity is continued, if the charging device is disconnected, the timer is closed, charging is stopped, and no further subsequent steps are executed.

And acquiring the first full charge for the nth time, wherein N is an integer greater than 1, namely acquiring the first full charge for one time every second preset time from the time when the time reaches the first preset time until the electronic equipment is disconnected with the charging equipment. The obtained N-1 th first full charge amount is the N-1 th second full charge amount, the N-1 th second full charge amount is the second full charge amount corresponding to the current temperature of the battery obtained based on the first corresponding relation after the N-1 th first full charge amount is obtained, N is an integer larger than 1, and the 1 st first full charge amount is preset electric quantity.

After the first full charge is obtained for the first time and steps S302 to S304 are performed, when the first full charge is obtained for the second time, the first full charge obtained for the second time is the second full charge obtained for the first time, and then the first full charge is obtained in the same way as the second full charge obtained for the first time.

Based on the above-mentioned first and nth processes of acquiring the first full charge amount, the battery charging method of the embodiment of the present disclosure is:

When the electric quantity of the battery in the charging process reaches the preset electric quantity, detecting the duration of the electric quantity of the battery in the preset electric quantity, when the duration reaches the first preset duration, determining the preset electric quantity as a first full charge quantity, executing steps S302-S304, and then taking the second full charge quantity obtained last time as the first full charge quantity in the circulating process when the next cycle starts, and executing steps S302-S304 again until the electronic equipment is disconnected with the charging equipment. The time point of starting each cycle from the second time is a time point which is separated from the first time point by N-1 second preset time length, and the first time point is a time point when the time length reaches the first preset time length.

In the embodiment of the disclosure, the first full charge amount is repeatedly executed, the second full charge amount corresponding to the current temperature of the battery is obtained, the full charge amount of the battery is modified from the first full charge amount to the second full charge amount, and the full charge amount of the battery can be adjusted in real time based on the process of charging the second full charge amount, so that the battery of the electronic equipment is prevented from being in a high-temperature and high-pressure state for a long time, the service life of the battery is prolonged, and the aging of the battery is prolonged.

Fig. 5 is a flowchart illustrating another battery charging method performed by an electronic device, see fig. 5, according to an exemplary embodiment, the method comprising the steps of:

step S501 obtains a first full charge amount of a battery of the electronic device, the first full charge amount being a current full charge amount of the battery.

Step S502, based on the first correspondence, obtains a second full charge corresponding to the current temperature of the battery.

Step S503, the full charge of the battery is modified from the first full charge to the second full charge.

The embodiments of steps S501-S503 are the same as the embodiments of steps S301-S303 described above, and will not be described again here.

After step S503, charging based on the second full charge amount includes charging the battery based on a relationship between the second full charge amount and the first full charge amount so that the amount of electricity of the battery is adjusted to the second full charge amount. Three different charging situations are described below by means of steps S504-S506.

In step S504, when the second full charge amount is smaller than the first full charge amount, the battery is controlled to discharge until the electric quantity of the battery decreases to the second full charge amount.

When the second full charge is smaller than the first full charge, the current electric quantity of the battery is higher, and the electric quantity of the battery needs to be reduced, namely, the battery is controlled to discharge until the electric quantity of the battery is reduced to the second full charge.

In some embodiments, the electronic device includes a battery charging path for charging the battery and a system power path for powering a system of the electronic device. The control of the battery discharge until the battery capacity drops to a second full charge comprises the control of the disconnection of the battery charging path and the system power supply path until the battery capacity drops to the second full charge, the control of the battery charging path remaining disconnected and the system power supply path being connected.

The battery charging path and the system power supply path are controlled to be disconnected, namely the electronic equipment is connected with the charging equipment, but the charging equipment does not supply power to the electronic equipment any more, the battery of the electronic equipment is required to supply power to the system of the electronic equipment, the electric quantity of the battery is consumed, the battery discharges when the battery supplies power to the system until the electric quantity of the battery is reduced to the second full charge, the battery charging path is controlled to be disconnected, and the system power supply path is connected, namely the charging equipment supplies power to the system without charging the battery, so that the electric quantity of the battery is adjusted to the second full charge.

In step S505, when the second full charge amount is greater than the first full charge amount, the battery is controlled to be charged until the electric quantity of the battery is increased to the second full charge amount.

Under the condition that the second full charge amount is larger than the first full charge amount, the current electric quantity of the battery is lower, and the electric quantity of the battery needs to be improved, namely, the battery is controlled to be charged until the electric quantity of the battery is improved to the second full charge amount.

In some embodiments, controlling the battery to charge until the charge level of the battery rises to a second full charge level includes controlling the battery charging path to connect with the system power path until the charge level of the battery rises to the second full charge level, controlling the battery charging path to disconnect and the system power path to remain connected.

The battery charging path is controlled to be connected with the system power supply path, even if the charging equipment charges the battery of the electronic equipment and supplies power for the system of the electronic equipment, until the electric quantity of the battery is increased to the second full charge, the battery charging path is controlled to be disconnected, and the system power supply path is kept connected, namely the charging equipment supplies power for the system and does not charge the battery any more, so that the electric quantity of the battery is adjusted to the second full charge.

In step S506, when the second full charge amount is equal to the first full charge amount, the battery is stopped from being charged.

And under the condition that the second full charge amount is equal to the first full charge amount, the current electric quantity of the battery is proper, and the electric quantity of the battery is not required to be changed, namely, the battery is stopped being charged.

In some embodiments, stopping charging the battery includes controlling the battery charging path to disconnect, the system power path to connect, i.e., the charging device powers the system without charging the battery.

In the above-described charging process, the electronic device and the charging device are kept connected, and in another embodiment, the charging is stopped after the electronic device and the charging device are disconnected.

In the embodiment of the disclosure, aiming at the electric quantity of the battery under different conditions, different control modes are adopted, so that the full charge quantity of the battery is adjusted to be the second full charge quantity, namely, the full charge quantity of the battery is adjusted to be the electric quantity suitable for the current temperature of the battery, thereby avoiding the battery of the electronic equipment from being in a high-temperature and high-pressure state for a long time, optimizing the service life of the battery and delaying the aging of the battery.

Fig. 6 is a flowchart illustrating another battery charging method performed by an electronic device, see fig. 6, according to an exemplary embodiment, the method comprising the steps of:

Step S601 obtains a first full charge amount of the battery and a first complex charge amount corresponding to the first full charge amount.

The electronic device is recharged during the charging process, and the recharge amount of the battery is changed when the full charge amount of the battery is changed. The first complex charge amount is a complex charge amount when the full charge amount of the electronic device is the first full charge amount, and each time the first full charge amount is acquired, the first complex charge amount corresponding to the first full charge amount is acquired. For example, the first full charge amount obtained for the first time is 100%, and the first complex charge amount is 98%.

Step S602, based on the first correspondence and the second correspondence, obtains a second full charge amount and a second complex charge amount corresponding to the current temperature of the battery.

The second corresponding relation is a corresponding relation between the temperature of the battery and the complex charge amount, the second complex charge amount is a complex charge amount which is more suitable for the current temperature of the battery, and the second complex charge amount may be higher than the first complex charge amount, may be lower than the first complex charge amount, and may be the same as the first complex charge amount.

For example, the first correspondence relationship and the second correspondence relationship are shown in the following table 1:

TABLE 1

Temperature of battery	Full charge amount	Complex charge amount
			Less than or equal to 40 DEG	100%	98%
Greater than 40 degrees and less than or equal to 42 degrees	90%	88%
			Greater than 42 degrees and less than or equal to 44 degrees	80%	78%
More than 44 degrees and less than or equal to 46 degrees	70%	68%
			Greater than 46 degrees	60%	58%

The correspondence in table 1 is an example, and in another embodiment, other correspondence may be set.

Note that table 1 is an example, and in table 1, the complex charge amount changes with the full charge amount, and in another embodiment, the complex charge amount is smaller than the full charge amount, and does not necessarily need to change with the full charge amount. For example, the full charge amount is 100% when the temperature of the battery is 40 degrees or less, 95% when the temperature of the battery is 40 degrees or more and 41 degrees or less, and 90% when the temperature of the battery is 41 degrees or less.

Step S603, the full charge amount of the battery is modified from the first full charge amount to the second full charge amount, and the double charge amount of the battery is modified from the first double charge amount to the second double charge amount.

Step S604, charging is performed based on the second full charge amount and the second complex charge amount.

Charging is performed based on the second full charge amount and the second complex charge amount, including any one of the following cases:

And under the condition that the second full charge amount is smaller than the first full charge amount, controlling a charging passage between the electronic equipment and the charging equipment to be disconnected until the electric quantity of the battery is reduced to the second full charge amount, controlling a battery charging passage to be disconnected and a system power supply passage to be connected, controlling the battery charging passage to be connected and the system power supply passage to be connected after the electric quantity of the battery is reduced to a second complex charge amount from the second full charge amount until the electric quantity of the battery is increased to the second full charge amount, and then, after the electric quantity of the battery is reduced to the second complex charge amount again, charging the battery again.

And under the condition that the second full charge amount is larger than the first full charge amount, controlling the connection of the charging paths until the electric quantity of the battery is increased to the second full charge amount, controlling the disconnection of the charging paths of the battery and the connection of the system power supply paths, controlling the connection of the charging paths of the battery and the connection of the system power supply paths after the electric quantity of the battery is reduced from the second full charge amount to the second complex charge amount until the electric quantity of the battery is increased to the second full charge amount, and then charging the battery again after the electric quantity of the battery is reduced to the second complex charge amount again.

And under the condition that the second full charge amount is equal to the first full charge amount, controlling the battery charging passage to be disconnected and the system power supply passage to be connected, after the electric quantity of the battery is reduced from the second full charge amount to the second complex charge amount, controlling the battery charging passage to be connected and the system power supply passage to be connected until the electric quantity of the battery is increased to the second full charge amount, and then, after the electric quantity of the battery is reduced to the second complex charge amount again, charging the battery again.
