Problems solved by technology

[0004] 1. If a charger with a small output power is used to charge the mobile phone, and the charging power required by the mobile phone charging solution is greater than the maximum output power of the charger, the charger will not be able to output such a large power and cannot work normally;
[0005] 2. If a charger with a larger output power is used to charge the mobile phone, and the charging power required by the mobile phone charging solution is lower than the maximum output power of the charger, the charger will not be able to exert its maximum effect
[0006] Thereby the charging technology of existing mobile terminal still needs to improve and improve

Embodiment Construction

[0034] The invention provides a mobile terminal for automatically setting the charging current and its implementation method, which can unify the electrical characteristics of the mobile terminal during charging and make the mobile terminal electrically compatible, thereby realizing that one charger can charge mobile terminals of different brands. The mobile terminal is a mobile phone. The invention unifies the electrical characteristics of mobile phone charging. When a user buys a new mobile phone, there is no need to purchase another mobile phone charger, which saves the cost of mobile phone accessories and realizes the unification of mobile phone chargers.

[0035] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used t...

Abstract

The invention discloses a mobile terminal of automatically setting a charging current and an implementation method thereof. The mobile terminal is provided with a charging port, wherein the charging port comprises a charging circuit, a PMIC (Power Management Integrated Circuit) module provided with the charging current, a first voltage detection module used for detecting a charging voltage, a current detection module used for detecting the charging current, and a second voltage detection module used for detecting the output voltage of a charger. The mobile terminal can obtain the maximum charging current of the charger through the second voltage detection module detecting the output voltage of the charger in real time and the PMIC module judging if the voltage is more than the preset voltage of the mobile terminal. Besides, the maximum charging current is set as the final charging current of the mobile terminal, and the charging efficiency of the mobile terminal is improved. When charged, the mobile terminal can automatically set the charging current according to chargers of different powers, and can realize electric compatibility.

Description

technical field [0001] The invention relates to the charging technology of a mobile terminal, in particular to a mobile terminal which automatically sets a charging current and an implementation method thereof. Background technique [0002] There are many kinds of mobile phone chargers on the market, and the interfaces, electrical characteristics, and especially the power curve (voltage-current curve) of the charger are also different. In order to unify mobile phone chargers, the Ministry of Industry and Information Technology of my country is also formulating relevant standards for mobile phone charging interfaces, so that users do not need to purchase a mobile phone charger at the same time when purchasing a mobile phone. [0003] The above method only allows users to plug in different brands of chargers on one type of mobile phone on the interface of the charger, but the following two problems need to be solved on the electrical side of the mobile phone: [0004] 1. If a...
