Embodiment Construction

[0058] In order to be able to adjust the charging parameters (charging voltage, charging current, charging mode, etc.) in real time according to the state parameters of the battery (temperature, state of charge, voltage, etc.), the embodiment of the present invention pre-establishes multiple parameter mapping relationships. The multiple parameter mapping relationships respectively correspond to multiple temperatures, and each parameter mapping relationship is used to indicate the mapping relationship between the state of charge of the battery and the charging parameter at the temperature corresponding to each parameter mapping relationship.

[0059] In actual use, the target parameter mapping relationship corresponding to the current temperature can be selected from multiple parameter mapping relationships based on the current temperature of the battery; and then the current charging parameters can be determined through the target parameter mapping relationship according to the ...

Abstract

Embodiments of the present invention provide a charging method, an adapter, a mobile terminal and a charging system. The adapter and the mobile terminal exchange the state parameters of the battery through two-way communication technology, and adjust the charging parameters of the adapter in real time based on the state parameters of the battery, which improves the flexibility of the charging process.

Description

technical field [0001] Embodiments of the present invention relate to the field of charging, and more specifically, relate to a charging method, adapter, mobile terminal and charging system. Background technique [0002] At present, mobile terminals (such as smart phones) are more and more favored by consumers, but the mobile terminals consume a lot of power and usually need to be charged frequently. [0003] In the prior art, the charging modes selectable by the adapter include constant current mode, constant voltage mode or pulse mode. Once the charging mode of the adapter is determined, the adapter will charge the mobile terminal according to the fixed mode. This charging mode is not flexible enough, and the charging effect is poor. Contents of the invention [0004] The present application provides a charging method, an adapter, a mobile terminal and a charging system, so as to improve the flexibility of the charging process of the mobile terminal. [0005] In the f...
