Detailed Description

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

Fig. 1 is a flow chart illustrating a battery management method according to an exemplary embodiment. The method may be used in a terminal device, as shown in fig. 1, which comprises the following steps.

In step S11, when it is detected that the terminal device executes the first function and the first portion of the power of the battery of the terminal device drops to a first threshold power, a prompt message for enabling the standby power is displayed, where the first threshold power is determined according to the minimum power required to execute the first function.

In step S12, when an operation to enable a backup amount of electricity is detected, the backup amount of electricity is enabled, the backup amount of electricity being a part of the second portion of electricity of the battery.

The first threshold amount of power may be equal to the minimum amount of power required to perform the first function or slightly higher than the minimum amount of power required to perform the first function to give the user time to make decisions and selections.

The discharge cutoff voltage may be used to represent the lowest voltage that the battery will allow for discharge under normal use conditions. In general, the battery can be controlled by the protection circuit to stop discharging before the voltage is reduced to the discharge cut-off voltage, so that the battery is prevented from being damaged.

Fig. 2a is a schematic diagram illustrating power distribution according to an exemplary embodiment. As shown in fig. 2a, a battery 200 of a terminal device, for example, a lithium battery, may include a first part 201 and a second part 202, wherein the first part is an electric quantity that can be used normally. When the battery voltage drops to a discharge cut-off voltage (also referred to as a safe discharge voltage, a discharge termination voltage, or the like) when the first part of the electric quantity is used up, a battery protection circuit in the terminal device may control the terminal device to shut down to prevent the battery from being damaged by over-discharge, and at this time, a second part of the electric quantity remains in the battery, and in the related art, the second part of the electric quantity is not used by the terminal device.

Alternatively, as shown in fig. 2a, the reserved value as the second part of the power amount 202 may be divided from the power amount available for normal use, and the first part of the power amount may be a part of the power amount available for normal use except for the second part.

FIG. 2b is a schematic diagram of a terminal device display interface shown in accordance with an example embodiment. Taking the first function as an example of a call function, in a process of a call performed by a user using a mobile phone, if a first part of electricity quantity is reduced to the minimum electricity quantity required for executing the first function, that is, the first part of electricity quantity is not enough to support the call function, the mobile phone may display a prompt message for enabling the standby electricity quantity, for example, "whether the standby electricity quantity is enabled" shown in fig. 2b, and if the user performs an operation for enabling the standby electricity quantity, for example, triggering the option "yes," the terminal device enables the standby electricity quantity, for example, enabling the standby electricity quantity 202a in fig. 2 a. The call is continued by enabling standby power to avoid the termination of important calls.

According to the embodiment of the disclosure, in the process of executing the first function by using the terminal device, if the first part of power amount is reduced to the first threshold power amount, the first function can be continuously executed by enabling a part of the second part of power amount (namely, the standby power amount), so that the first function is prevented from being terminated due to insufficient power amount. For example, the embodiment of the disclosure can provide emergency power when the user has an emergency demand, and can ensure that the key functions of the terminal equipment are not immediately cut off due to insufficient power in an extreme case.

The first function may include a voice service call function, a data service call function, a lighting function, a payment function, a function of specifying the use of an application, etc., and the first function may be any key function that a user does not want to be terminated due to a power shortage, which is not limited by the present disclosure. In one possible implementation, a setup option may be provided to allow the user to set up the specific content of the first function.

In one possible implementation, if no operation to enable the standby power is detected, or if no operation to enable the standby power is detected (e.g., detecting that option "no" is triggered), the first function may be terminated, and the terminal device may be powered down to protect the battery when the first portion of power is exhausted.

In a possible implementation manner, if the terminal device is in a charging state, the prompt message may not be displayed, and the standby battery is not enabled.

In a possible implementation manner, a corresponding relationship between the first function and the minimum electric quantity required for executing the first function may be preset, so as to determine the minimum electric quantity corresponding to the currently executed first function according to the currently executed first function, and further determine the first threshold electric quantity.

Fig. 3 is a flow diagram illustrating a method of battery management according to an example embodiment, which in one possible implementation, as shown in fig. 3, further includes:

in step S13, determining a usage environment of the terminal device;

in step S14, the minimum amount of power required to perform the first function is determined according to the usage environment.

The minimum amount of power required to perform the first function may be related to the usage environment, such as the strength of the communication signal, the brightness of the environment, and the like. For example, if the communication signal is strong, the minimum amount of power required for the call function is large. If the ambient brightness is high, the screen brightness of the terminal device is high, and the minimum electric quantity required by the first function needing interface display, such as conversation, payment and the like, is also high.

The correspondence between the minimum amount of electricity required for the first function and the usage environment may be set in advance, whereby the minimum amount of electricity required to execute the first function is determined according to the usage environment, thereby accurately judging an appropriate timing to enable the standby amount of electricity.

In one possible implementation manner, a circuit for controlling the standby power to be turned on or off may be provided, and the standby power is enabled by turning on the circuit, and the specific manner for enabling the standby power is not limited by the present disclosure.

Fig. 4 is a flow chart illustrating a method of battery management according to an example embodiment. In a possible implementation manner, the second portion of power includes multiple backup power consumption amounts, as shown in fig. 4, the method further includes:

in step S15, when the enabled standby power consumption drops to a second threshold power consumption, if it is detected that the terminal device executes the first function, displaying a prompt message for enabling the standby power consumption;

in step S16, upon detection of an operation to enable the backup power amount, another backup power amount is enabled.

The second threshold electric quantity may be the same as the first threshold electric quantity, or may be different from the first threshold electric quantity. For example, the first threshold amount of power and the second threshold amount of power may both be equal to a minimum amount of power required to perform the first function. The first threshold amount of power may be slightly higher than the minimum amount of power required to perform the first function, and the second threshold amount of power may be equal to the minimum amount of power required to perform the first function.

Still taking fig. 2a as an example, the second portion of the electricity may be divided into multiple backup electricity quantities, such as backup electricity quantity 202a, backup electricity quantity 202b, and backup electricity quantity 202 c. And when the terminal equipment is detected to execute the first function and the first part of electric quantity is reduced to the first threshold electric quantity, displaying prompt information for starting the standby electric quantity. Upon detecting an operation to enable the backup amount, the backup amount 202a is enabled. When detecting that the standby power consumption 202a is reduced to a second threshold value, if detecting that the terminal equipment executes the first function, displaying prompt information for starting the standby power consumption; upon detecting the operation to enable the backup amount, the backup amount 202b is enabled. After the backup power amount 202b falls to the second threshold power amount, steps S15 and S16 may be repeated until all available backup power amounts are used up.

In this way, the second part of electric quantity can be gradually used, so that the second part of electric quantity is reserved as far as possible on the premise of meeting the requirement of a user for executing the first function, the battery is prevented from being over-discharged, and the battery is protected.

The sum of all available spare power amounts may be equal to or less than the second part of power amount, that is, the second part of power amount may be allowed to be completely exhausted to maintain the execution of the first function to the maximum extent, and a part of the second part of power amount may be reserved to protect the battery.

Any appropriate means can be used to divide the second portion of electricity to form the standby electricity quantities. For example, the second portion of power may be divided equally to obtain the standby power amounts. The second portion of power may also be divided according to other principles, which are not limited by this disclosure.

Fig. 5 is a flow chart illustrating a battery management method according to an example embodiment, in one possible implementation, the second portion of power includes a plurality of backup power amounts, each backup power amount corresponds to each voltage interval between a discharge cutoff voltage and 0V, the backup voltages are sorted in order of the corresponding voltage intervals from high to low,

in step S11, when it is detected that the terminal device performs the first function and the first portion of the battery of the terminal device decreases by the first threshold amount of power, displaying a prompt message for enabling the standby power may include:

in step S111, when it is detected that the terminal device executes the first function and the first part of the electric quantity of the battery of the terminal device decreases to the first standby electric quantity, displaying a prompt message for enabling the standby electric quantity with the top ranking from the available standby electric quantities;

in step S12, when the operation of enabling the backup power amount is detected, enabling the backup power amount may include:

in step S121, when an operation to enable the backup amount is detected, the most-ranked backup amount is enabled.

For example, m voltage intervals, i.e., V1-V2 and V2-V3 … … Vm-0, may be divided between the discharge cutoff voltages V1 and 0V, and each voltage interval may correspond to one spare power consumption, for example, the amount of power consumed by the battery voltage decreasing from V1 to V2 may be detected as the spare power consumption 202a, the amount of power consumed by the battery voltage decreasing from V2 to V3 may be detected as the spare power consumption 202b, and so on. The standby voltages are sorted according to the voltage intervals corresponding to the standby voltages, wherein the standby voltage 202a is the first voltage and then the

standby voltages

202b and 202c … … are arranged. When it is detected that the terminal device executes the first function and the first part of the electricity quantity of the battery of the terminal device is reduced to the first threshold electricity quantity, if the standby electricity quantity 202a is the first standby electricity quantity in the current available standby electricity quantities, a prompt message for enabling the standby electricity quantity 202a is displayed, and when the operation of enabling the standby electricity quantity is detected, the standby electricity quantity 202a is enabled, and so on.

In this way, the divided standby power consumption is matched with the power consumption consumed by the voltage drop, and the standby power consumption is started in sequence along with the voltage drop, so that the started standby power consumption can better meet the requirement of maintaining the first function.

For example, as shown in FIG. 2b, the following prompt messages may be displayed: "the call is about to be terminated when the battery power is insufficient, the standby power 2 can be started, the standby power 2 is started for 3 times, the call can be prolonged for 5 minutes after the standby power 2 is started, the battery capacity is lost x A & h after the standby power 2 is started, and the battery cycle number is lost for y times".

The standby power belongs to the second part of the electric quantity of the battery, the standby power is started, the service life of the first function is prolonged, meanwhile, the battery capacity, the battery cycle number and the like can be lost, and through the prompt information, a user can balance when determining whether the standby power is started or not so as to make a proper judgment.

In a possible implementation manner, the relevant information of the above prompt information can be predetermined through experimental tests, calculation or the like.

For example, it may be determined through testing or calculation that each amount of backup power can extend the time for the first function to perform. The loss of battery cycle times and the loss of battery capacity after each backup power is used p times can be tested. For example, if the spare power consumption is divided into voltage intervals from V1 to 0V, i.e., V1-V2 and V2-V3 … … Vm-0, each voltage interval can correspond to one spare power consumption, and the loss of the battery cycle count and the loss of the battery capacity can be tested when the voltage decreases from V1 to V2 the p time, so as to determine the loss of the battery cycle count and the loss of the battery capacity after the spare power consumption 202a is activated p times, and so on.

The test result can be stored in the terminal equipment, so that the content of the prompt message can be determined according to the enabled standby power quantity identification, the enabled times of the standby power quantity and other information.

Fig. 6 is a flow diagram illustrating a method of battery management according to an example embodiment, which in one possible implementation, as shown in fig. 6, further includes:

in step S17, recording the number of times the backup power amount is enabled;

in step S18, the presentation information is determined based on the number of times.

As indicated above, the prompting message may be related to the number of times the backup power is enabled, such as the number of times the backup power has been enabled, the loss of battery capacity after the backup power is enabled, and the loss of battery cycle number after the backup power is enabled.
