Charging line, charging system and charging method thereof

Abstract

The invention relates to the field of electronic equipment accessories, in particular to a charging line, a charging system and a charging method thereof. The charging line comprises at least one input end and at least two output ends, one output end is provided with a data access pin, the other output ends have no data access pin, and when only the output end provided with the data access pin is connected to the electronic equipment, the output end provides fast charging voltage for the connected electronic equipment; and when the output end without the data access pin is connected to the electronic equipment, all the output ends provide common charging voltage. According to the charging line and the charging system, the occurrence of unsafe accidents that charging equipment explodes or a user is burnt due to overhigh output power and overlarge generated heat when quick charging is still carried out when a plurality of interfaces are connected can be avoided. According to the charging system provided by the invention, the charging line capable of realizing voltage distribution is adopted, so that the diversified charging requirements can be met on the premise of ensuring the charging safety.

Description

【Technical field】 [0001] The invention relates to the field of electronic circuits, in particular to a novel charging line, a charging system and a charging method thereof. 【Background technique】 [0002] With the development of science and technology, people have frequently used electronic devices in their daily life. Due to the different charging interfaces and charging voltages of different electronic devices, it is often necessary to use multiple data lines or multi-interface chargers to meet the needs of electronic devices. charging needs. [0003] The emergence of one-to-many charging cables has been favored by consumers. However, although the existing one-to-two and one-to-three charging cables can satisfy multiple electronic devices plugged in and charged at the same time, the existing data cables cannot meet the needs of fast charging, and there will be electrical conflicts when multiple interfaces are used at the same time.

Problems solved by technology

However, although the existing one-to-two and one-to-three charging cables can satisfy multiple electronic devices plugged in and charged at the same time, the existing data cables cannot meet the needs of fast charging, and there will be electrical conflicts when multiple interfaces are used at the same time. Cause abnormal charging of electronic equipment

[0004] In addition, in order to meet the problem of no conflict between multi-interface charging in existing multi-interface chargers, it is often necessary to build a variety of control chips into the charger, and in order to meet the charging needs, it is large and heavy, not easy to use. easy to carry
