First embodiment

Referring to fig. 3, fig. 3 is a flowchart illustrating a charging control method according to a first embodiment, the method including the steps of:

step S10, acquiring at least one of an environment temperature, a chip temperature of a charging chip and a board temperature of a circuit board;

optionally, the environmental temperature may refer to a temperature corresponding to a space environment where the terminal device is located; the chip temperature refers to the temperature corresponding to the surface of a charging chip of the intelligent terminal or the junction temperature of the charging chip; the board temperature refers to the temperature corresponding to the circuit board of the intelligent terminal.

Optionally, the ambient temperature of the space where the intelligent terminal is located is obtained by acquiring the temperature of the space where the intelligent terminal is located through a first temperature sensor arranged on the intelligent terminal, or by acquiring the temperature of the space where the intelligent terminal is located through a temperature detection device capable of transmitting data information with the intelligent terminal, and this step is not limited.

Optionally, first temperature sensor sets up in intelligent terminal keeps away from intelligent terminal's one side of the source that generates heat like charging chip and circuit board to reduce intelligent terminal's the influence of the source that generates heat to the ambient temperature who gathers, improve ambient temperature's collection accuracy.

Optionally, the chip temperature of the charging chip may be obtained by obtaining a junction temperature of the chip, or may be obtained by detecting through a second temperature sensor disposed on the charging chip, which is not limited to this step.

Optionally, the board temperature of the circuit board may be obtained by collecting the temperature of the thermistor of the circuit board, determining the board temperature of the circuit board according to the temperature of the thermistor of the circuit board, or by collecting the board temperature obtained by a third temperature sensor disposed on the circuit board, or by collecting at least two temperature values corresponding to different radius positions based on the circuit board as a circle center, and determining the board temperature obtained according to an average temperature value of the at least two temperature values. Optionally, the circuit board may be regarded as a heat source, and based on the heat source as a center of a circle, the radius and the temperature are in a negative correlation relationship, that is, the radius is larger, the temperature is smaller, the board temperature of the circuit board is determined by obtaining at least two temperatures at positions corresponding to different radii and according to an average temperature value of the at least two temperature values, so as to accurately obtain the board temperature of the circuit board, which is not limited herein.

Step S20, determining or generating a corresponding predicted charging temperature after a preset time according to at least one of the environment temperature, the chip temperature and the board temperature;

optionally, in an actual application process, due to the charging process and the hysteresis of heat transfer, the detected charging temperature based on real-time detection is smaller than the actual charging temperature, and when the charging current of the intelligent terminal is adjusted based on the detected charging temperature, the charging temperature of the intelligent terminal continuously rises due to the fact that the preset temperature for adjusting the charging temperature of the intelligent terminal is not reached. When the charging temperature that detects reaches the preset temperature that intelligent terminal's charging temperature adjusted, show that intelligent terminal's actual charging temperature has been greater than preset temperature, even if based on the charging temperature of the intelligent terminal who detects adjusts intelligent terminal's charging current, with reduce intelligent terminal's charging temperature, make charging temperature be less than preset temperature, also need to continuously adjust for a certain time in order to reduce intelligent terminal's charging temperature, and can't in time adjust intelligent terminal's charging temperature, the degree of accuracy of charging control has been reduced, lead to charging temperature too high easily and withdraw from the mode of filling soon, reduce charge efficiency. Optionally, the charging chip is easily damaged due to the fact that the charging temperature of the intelligent terminal is too high, and the service life of the charging chip is shortened.

Optionally, the preset time period may be preset, for example, set based on experience values of professionals in the battery charging industry, so as to obtain a corresponding predicted charging temperature after the preset time period in advance, and then determine that the charging temperature of the intelligent terminal is about to be greater than or equal to the preset temperature through the predicted charging temperature. When the charging temperature is too high and needs to be reduced, the charging current of the intelligent terminal is adjusted according to the predicted charging temperature so as to adjust the charging current of the intelligent terminal in advance, the charging temperature of the intelligent terminal is adjusted in time, and the problem that the charging control is inaccurate because the real-time charging temperature detected due to the hysteresis of heat transfer is smaller than the actual charging temperature and cannot be adjusted in time based on the actual charging temperature is solved.

Optionally, the preset time duration can also be based on the hysteresis of heat conduction, the hysteresis time duration of heat conduction is determined, the preset time duration is determined according to the hysteresis time duration, so that the corresponding predicted charging temperature after the preset time duration is the actual charging temperature corresponding to the current time point, the charging current of the intelligent terminal is timely adjusted based on the accurate actual charging temperature, the purposes of timely and accurately adjusting the charging temperature of the intelligent terminal and reducing the charging temperature of the intelligent terminal are achieved, the accuracy of charging control is improved, the charging efficiency is improved, the charging chip is prevented from being damaged due to overhigh charging temperature, and the service life of the charging chip is shortened.

Alternatively, it can be understood that, assuming that the preset time period may be 1s (second), if the current time point is 17; assuming that the preset time period can take 5s (seconds), if the current time point is 17.

Optionally, the predicted charging temperature corresponding to the preset time duration is determined according to the environment temperature, the chip temperature and the board temperature, a mapping relation among the environment temperature, the chip temperature, the board temperature and the charging temperature corresponding to the preset time duration may be preset, and based on the mapping relation, when the environment temperature, the chip temperature and the board temperature are known, the charging temperature corresponding to the preset time duration is obtained to serve as the predicted charging temperature corresponding to the preset time duration.

Optionally, step S20 includes:

inputting at least one of the ambient temperature, the chip temperature, and the board temperature into a charging temperature prediction model to obtain the predicted charging temperature.

It should be noted that, the specific implementation of this step may refer to the second embodiment, and is not specifically described in this embodiment.

And step S30, controlling the charging current according to the predicted charging temperature.

Optionally, after step S30, the method further includes: acquiring at least two actual charging temperatures within a preset monitoring time of the intelligent terminal; and when the temperature difference value between any two target charging temperatures in the at least two actual charging temperatures is smaller than or equal to a preset temperature difference, controlling the intelligent terminal to continuously charge according to the adjusted charging current.

Optionally, under the same heat dissipation condition, the larger the temperature difference, the more the heat transfer, the greater the heat transfer efficiency, the larger the charging earlier stage accessible increases the charging current, so that the charging temperature of the intelligent terminal rapidly rises and reduces the temperature difference, the later stage of charging, the accessible reduces the charging current, and the final charging temperature is less than the preset temperature, so that after the heating element of the intelligent terminal and the space environment where the intelligent terminal is located generate heat and dissipate heat to reach thermal balance, the charging temperature of the intelligent terminal finally tends to be stable. Alternatively, the preset temperature may be a set temperature for adjusting a charging temperature of the smart terminal.

And then when the charging temperature of the intelligent terminal is determined to be more than or equal to the preset temperature through predicting the charging temperature and the charging temperature is required to be reduced due to overhigh charging temperature, the charging current of the intelligent terminal is adjusted according to the predicted charging temperature so as to adjust the charging current of the intelligent terminal in advance. The charging temperature of the intelligent terminal is timely adjusted, and the problem that charging control is inaccurate due to the fact that the detected real-time charging temperature is smaller than the actual charging temperature and cannot be timely adjusted based on the actual charging temperature due to the fact that the lag of heat transfer is caused is avoided.
