Illustratively, the correspondence relationship is a one-to-one correspondence relationship.

Step 203, controlling the charging current of the charger by using a charging control strategy according to the device temperature and the temperature threshold of the terminal device, wherein the charging control strategy is used for indicating that the device temperature is kept smaller than or equal to the temperature threshold in the charging process, or the battery current of the terminal device is kept at a preset minimum battery current threshold.

The terminal equipment obtains the current equipment temperature of the terminal equipment, and the charging current of the charger is adjusted or not adjusted by adopting a charging control strategy according to the equipment temperature and the temperature threshold.

Optionally, the charging control strategy includes one of a first charging control strategy and a second charging control strategy, the first charging control strategy is used for indicating that the temperature of the equipment is kept less than or equal to the temperature threshold value in the charging process, and the second charging control strategy is used for indicating that the battery current of the terminal equipment is kept at a preset minimum battery current threshold value. It should be noted that, the description of the first charging control strategy and the second charging control strategy may refer to the description of the following embodiments, which will not be described first.

The device temperature is used for indicating the heating degree of the terminal device, and the device temperature and the heating degree of the terminal device are in a positive correlation relationship, that is, the higher the device temperature is, the higher the heating degree of the terminal device is.

Optionally, the device temperature of the terminal device is a temperature of a detection position of a temperature sensor of the terminal device, or a temperature of a specified position in the terminal device, or a surface temperature of the terminal device.

In the related art, if the battery power of the terminal device is low during the charging process and the foreground application power consumption of the terminal device is high at this time, the device temperature of the terminal device is high, so that the charging current of the charger is adjusted to a small value, and the charging speed is slowed. Because the battery power is low at this time, if the foreground application is still running, the battery power of the terminal device may increase slowly, and the charging effect is not good. In addition, in a scene that the foreground application power consumption is high, the charging current is adjusted to a small value, and most of the charging current is supplied to the system for consumption, so that the current actually charged into the battery, namely the battery current, is further reduced. Therefore, under the condition of power consumption fluctuation, the battery current of the terminal device is unstable, so that the electric quantity increasing speed is not basically ensured, the electric quantity of the battery is not changed for a long time in the charging process, and the charging effect is further influenced. Therefore, the charging control method provided by the embodiment of the application also determines a higher temperature threshold value when the battery power is low, so that the charging speed is preferentially ensured in the charging speed and the charging heating degree, and the battery power is separated from the low power region as soon as possible; and determining a lower temperature threshold when the battery power is high so as to preferentially ensure the charging heating degree and inhibit the device temperature of the terminal device from rising. In addition, under the high-temperature and high-power-consumption scene, the terminal equipment adopts a second charging control strategy to control the charging current of the charger, namely, a lowest battery current threshold value is preset, the battery current of the terminal equipment is kept to be the preset lowest battery current threshold value in the charging process, and the most basic charging speed is ensured.

Referring to fig. 3, a flowchart of a charging control method provided in another exemplary embodiment of the present application is shown, where the method is used in the terminal device shown in fig. 1. The method includes, but is not limited to, the following steps.

Step 301, acquiring the current battery capacity of the terminal device under the condition of charging through the charger.

Step 302, inputting the battery power into a preset temperature control model, and outputting to obtain a corresponding temperature threshold, where the preset temperature control model is used to indicate that the temperature threshold and the battery power are in a negative correlation relationship.

The terminal equipment obtains a preset temperature control model, inputs the electric quantity of the battery into the preset temperature control model and outputs the electric quantity of the battery to obtain a corresponding temperature threshold value.

The preset temperature control model is used for indicating that a negative correlation relationship exists between the temperature threshold and the electric quantity of the battery. Namely, the preset temperature control model is used for indicating that the following relation is satisfied between the temperature threshold and the battery capacity: if the corresponding temperature threshold value when the battery electric quantity is the first temperature threshold value, the corresponding temperature threshold value when the battery electric quantity is the second temperature threshold value, and the first battery electric quantity is larger than the second battery electric quantity, the first temperature threshold value is smaller than or equal to the second temperature threshold value.
