Description

Power adapter protection method and system based on temperature and computer equipment

Technical Field

The invention relates to the technical field of charging equipment of mobile terminals, in particular to a temperature-based power adapter protection method, a temperature-based power adapter protection system and computer equipment.

Background

Manufacturers of existing mobile terminals (such as smartphones, tablets, smartwatches, etc.) are continuously increasing the charging power to shorten the charging time of the battery in order to meet the fast-paced demands of people. However, as the charging power of the mobile terminal is continuously increased, the requirements and manufacturing costs of the power adapter are correspondingly increased.

In addition, the number of users who have a plurality of mobile terminals at the same time is also increasing, and there is not difference in the charging power of different terminals. Therefore, if dedicated power adapters are required to be respectively configured for different types or manufacturers of mobile terminals, the cost is increased and the resource waste is caused. Therefore, each manufacturer responds to the environmental protection policy, and the charging interfaces adopted by each mobile terminal which are introduced later are gradually unified, and even the power adapter is used as a selected accessory for the user to select.

In this case, a power adapter is introduced in the market to be compatible with the charging requirements of different mobile terminals. Because some mobile terminals adopt the quick charging technology, the mobile terminals can be quickly charged with extremely high power when being charged, although the temperature detection submodule is arranged in the terminal to detect the temperature of the battery so as to reduce the charging power when the temperature of the battery is too high, and prevent spontaneous combustion or the influence on the service life of the battery due to the too high temperature of the battery in the charging process.

However, the inventor finds that in the charging process, besides the service life of the battery is influenced due to high temperature, even spontaneous combustion occurs, the power adapter also has high temperature due to overlarge charging power for a long time, and further the electronic components in the power adapter have aging phenomena due to long-term high temperature, and once the circuit has high temperature after aging, the power adapter is easily broken due to overcurrent, so that the power adapter is finally damaged.

In addition, the inventor also found that although the present mobile terminal and the power adapter are compatible with different charging protocols, the mobile terminal always selects the current optimal charging mode in the charging process, for example, a fast charging protocol, namely high power is adopted in low battery, the trickle charging mode, namely low power is adopted after the battery is charged to 80%, and the power adapter is used for passively adjusting the output power in response to the selection of the mobile terminal. The power adapter is extremely passive in that the internal temperature is too high due to poor heat dissipation or when the internal components work abnormally, the original mode work is continuously maintained, the internal components are easily damaged, and even safety accidents are caused.

In summary, it is necessary to develop a method and a system for protecting a power adapter based on temperature, so as to adjust the working state of the power adapter based on temperature, protect the power adapter from working normally, further prolong the service life and improve the safety.
