Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely examples of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
The embodiments of the present invention will be described in detail below with reference to the accompanying drawings,
as shown in fig. 1, a first embodiment of the present invention provides an information processing method, including,
detecting the temperature of a battery core of the battery;
adjusting a first delay time of the battery and/or adjusting a cutoff voltage of the battery based on the temperature of the cell.
In this embodiment, the first delay time and/or the cut-off voltage of the battery may be adjusted based on the temperature of the battery cell, where the first delay time may be adjusted, the cut-off voltage may be adjusted, and the first delay time and the cut-off voltage may be adjusted at the same time. The first delay time corresponds to the off-voltage and represents a first delay time at the off-voltage. For example, generally, when the actual voltage of the battery exceeds a first delay time below the cut-off voltage, the system is shut down; the system relationship here refers to normal shutdown of the system, that is, shutdown is performed after the file is saved. When the actual voltage of the battery is below the cut-off voltage and does not exceed the first delay time, the system is not shut down temporarily; and the system will not shut down when the actual voltage of the battery is above the cutoff voltage.
In the prior art, the cut-off voltage and the first delay time under the cut-off voltage are both fixed values, and when the temperature is low, the actual voltage of the battery is easily lower than the cut-off voltage, so that the system is shut down under the condition that the battery still has electric quantity, and the system cannot work normally. In the present invention, the first delay time of the battery and/or the cut-off voltage of the battery may be adjusted based on the temperature of the battery cell, that is, the cut-off voltage of the battery and the first delay time at the cut-off voltage are not constant, and the cut-off voltage and the first delay time of the battery may be adjusted according to the temperature of the battery cell. In addition, the whole process is automatic, so that a few extra operations are brought to a user, and the user experience is good.

The second delay time can be adjusted, the undervoltage can also be adjusted, and the second delay time and the undervoltage can also be adjusted simultaneously. The second delay time corresponds to an under-voltage and represents a second delay time under the under-voltage. Generally, when the temperature of the battery cell is lower than the undervoltage of the battery and reaches the second delay time, the battery is powered off, where the power off of the battery refers to an abnormal shutdown condition, for example, a shutdown is performed before a file is saved.
In the prior art, generally, the undervoltage and the second delay time under the undervoltage are both fixed values, and when the temperature is low, the actual voltage of the battery is easily lower than the undervoltage, so that the battery is powered off under the condition that the battery still has electric quantity, and the battery cannot normally work, and some files may not be stored in time, so that the loss is brought to a user. In the invention, the second delay time of the battery and/or the undervoltage of the battery can be adjusted based on the temperature of the battery core, and when the temperature is reduced, the undervoltage can be reduced and/or the second delay time can be prolonged in real time based on the temperature of the battery core, so that the battery capacity can be fully released even at a lower temperature, and particularly the experience of a user in use at the low temperature can be improved.
In another embodiment, the system shuts down when the actual voltage of the battery is less than the cutoff voltage; when the actual voltage of the battery is less than the undervoltage, the battery is powered off; that is, the cutoff voltage is usually set higher than the undervoltage depending mainly on which condition the actual voltage of the battery satisfies.

In this embodiment, when the temperature of the battery cell is lower than the first specific value and the operation mode of the battery is determined to be in the discharge mode, the first delay time of the battery may be adjusted and/or the cut-off voltage of the battery may be adjusted. The specific adjusting method comprises the following steps: detecting a current value of the battery; adjusting a first delay time of the battery and/or adjusting a cutoff voltage of the battery based on the current value.

In one embodiment provided by the present invention, the off-voltage decreases with an increase in current value, and the first delay time increases with an increase in current value. In this embodiment, at a low temperature, if the battery is expected to operate normally, the cut-off voltage needs to be decreased and/or the first extension time needs to be increased, so as to make the actual voltage of the battery higher than the cut-off voltage as much as possible or to extend the time for shutting down the system at this time as much as possible, even if the actual voltage of the battery is lower than the cut-off voltage, so as to make the battery sufficiently discharged at the low temperature as much as possible.
In one embodiment, the cutoff voltage and the current value are in a linear relationship; the first delay time and the current value are in a linear relationship. For example, in one particular embodiment, the off-voltage and the current value have a relationship of:

For example, generally, when the actual voltage of the battery exceeds a first delay time below the cut-off voltage, the system is shut down; the system relationship here refers to normal shutdown of the system, that is, shutdown is performed after the file is saved. When the actual voltage of the battery is below the cut-off voltage and does not exceed the first delay time, the system is not shut down temporarily; and the system will not shut down when the actual voltage of the battery is above the cutoff voltage.
