However, those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present application.

In order to explain the above technical solutions of the present application, the following will be described by specific embodiments.

Example 1

This embodiment provides a charging method, which can be applied to any terminal device that has a rechargeable battery that needs to be charged, such as a mobile phone, tablet computer, notebook computer, smart bracelet, personal digital assistant, etc. Mobile terminal.

In specific applications, depending on the type of terminal device, any type of rechargeable battery can be selected according to actual needs, for example, a lithium ion battery.

As shown in FIG. 1, the charging method provided in this embodiment includes the following steps performed during the charging process:

Step S101: Obtain the current battery temperature every first preset time interval.

In a specific application, the charging process refers to a process after the charging interface of the terminal device is connected to a matching power adapter or charger and starts charging. The temperature of the battery can be detected by a temperature sensor built into the terminal device. The temperature sensor can be set at any position inside the terminal device according to actual needs. In order to improve accuracy, the temperature sensor can be set at a position close to the battery. The first preset time period can be set to any length of time according to actual needs, for example, any time length from 1 second to 10 seconds, which can be specifically 1 second, 3 seconds, 5 seconds, 7 seconds, 10 seconds, and so on.

Step S102: Determine a temperature interval to which the current battery temperature belongs.

In specific applications, several temperature intervals need to be set in advance, and the several temperature intervals cover all temperatures that may be reached during the battery charging process. The several temperature intervals may include a plurality of different temperature intervals where the temperature continuously changes.

Step S103: When the temperature interval to which the current battery temperature belongs changes, set the corresponding charging current and cut-off voltage according to the temperature interval to which the current battery temperature belongs.

In a specific application, a change in the temperature interval to which the current battery temperature belongs means that the current battery temperature changes relative to the temperature interval to which the battery temperature at the start of charging, for example, at the start of charging, the battery temperature belongs to the In a temperature interval, the current battery temperature in the charging process belongs to the second temperature interval, and the first temperature interval and the second temperature interval belong to different temperature intervals, it is considered that the temperature interval to which the current battery temperature belongs changes.

In a specific application, each temperature interval corresponds to a charging current, and each charging current corresponds to a cut-off voltage.

In one embodiment, before step S103 includes:

Establish the first correspondence between different temperature intervals and charging current;

Establish a second correspondence between different charging currents and cut-off voltages;

Correspondingly, step S103 includes:

The corresponding cut-off voltage is set according to the second correspondence and the charging current corresponding to the temperature interval to which the current battery temperature belongs.

In specific applications, the first correspondence relationship and the second correspondence relationship may be a mapping relationship, and the mapping relationship may exist in the form of a correspondence table or a look-up table (LUT, look-up-table), or may be displayed by having The input data of the same function of the look-up table is realized by searching other data tables or random storage (Random Access Memory, RAM) type storage media corresponding to the output data according to the input data.

As shown in FIG. 2, a correspondence table representing the first correspondence and the second correspondence is exemplarily shown; wherein, the first temperature interval corresponds to the charging current 1 and the cut-off voltage 1; the second temperature interval corresponds to the charging current 2 2. Cut-off voltage 2; ...; the Nth temperature interval corresponds to charging current N and cut-off voltage N.

In a specific application, the charging current and the corresponding cut-off voltage are different according to the battery capacity of the terminal device, and the first temperature interval, the second temperature interval, and the Nth temperature interval are temperature intervals where the temperature continuously changes . The first correspondence relationship and the second correspondence relationship may also be represented by two different correspondence tables, respectively. In order to avoid that the temperature of the battery happens to belong to two adjacent temperature intervals at the same time, the critical value of any two adjacent temperature intervals can be divided into one of the temperature intervals, so that the other temperature interval does not include the critical value.

Step S104: Charge the battery according to the charging current and the cut-off voltage, and return to step S101 (that is, obtain the current battery temperature every first preset time interval).

In specific applications, after the corresponding charging current and cut-off voltage are set according to the current temperature range of the battery, the battery is charged with the set charging current and cut-off voltage, and the process returns to step S101 to repeat steps S101 to S104, This cycle repeats until charging is stopped. The case of stopping charging includes: the user unplugs the power adapter or charger that is connected to the charging interface of the terminal device, the battery is fully charged, the terminal device, power adapter or charger fails and the charging cannot continue, the battery temperature is too high or Too low.

As shown in FIG. 3, in one embodiment, after step S301, it includes:

Step S302: Every second predetermined time interval, the lower limit value of the temperature range with a high temperature is increased by a second preset temperature value until the lower limit value of the temperature range with a high temperature is restored.

For example, the second preset temperature value can be set to any value within the range of 1 ° C to 6 ° C, which can be specifically 1 ° C, 2 ° C, 3 ° C, 4 ℃ or 6 ℃ etc. The first preset temperature value is an integer multiple of the second preset temperature value.

As shown in FIG. 4, it is exemplarily shown that when the temperature of the battery changes from belonging to the first temperature interval to belonging to the second temperature interval with high temperature, after the lower limit value of the second temperature interval decreases by the first preset temperature value, The second preset temperature value is increased every second preset time period until the recovery condition; wherein, the unshaded rectangular frame represents the first temperature interval, the shaded rectangular frame represents the second temperature interval, and the dotted line position is the time node.

In specific applications, the third preset temperature value can be set to any value according to actual needs. For example, the third preset temperature value can be set to any value within the range of 2 ° C to 6 ° C, specifically 2 ° C, 3 ℃, 4 ℃ or 6 ℃ etc.

In a specific application, when the current temperature range of the battery belongs to a low temperature range, the lower limit of the low temperature range is increased by a third preset temperature value to prevent the battery The temperature frequently shakes around the original lower limit of the low temperature range (that is, the temperature of the battery changes back and forth between the original temperature range to which it belongs and the low temperature range), to prevent the charging current and cutoff voltage from being Repeatedly set to different values to ensure the stability of the charging current and cut-off voltage, thereby improving the charging stability.

As shown in FIG. 3, in one embodiment, after step S303, it includes:

Step S304: Every third preset time interval, the upper limit of the low temperature interval is reduced by a fourth preset temperature value until the upper limit of the low temperature interval is restored.

For example, the fourth preset temperature value can be set to any value within the range of 1 ° C to 6 ° C, specifically 1 ° C, 2 ° C, 3 ° C, 4 ℃ or 6 ℃ etc. The third preset temperature value is an integer multiple of the fourth preset temperature value.

As shown in FIG. 5, it is exemplarily shown that when the temperature of the battery changes from belonging to the second temperature interval to belonging to the first temperature interval with a low temperature, the upper limit value of the first temperature interval increases after the third preset temperature value , The fourth preset temperature value is lowered every third preset time period until it recovers; where the unshaded rectangular frame represents the first temperature interval, the shaded rectangular frame represents the second temperature interval, and the dotted line position is the time node.
