Problems solved by technology

[0003] Currently, there are two main fast charging schemes: 1 high-voltage charging scheme (5V ~ 20V) and 2 low-voltage direct charging scheme (below 5V). The two schemes need to match different charging circuits on the mobile device side due to the different output voltages of the chargers. The two options are not compatible

Abstract

The invention discloses a charging system and method. The charging system comprises a charger, a charging circuit, a processor and a controller, wherein the charger is used for outputting a charging signal and charging a battery; the charging circuit is connected with the charger; the charging signal is used for charging the battery through the charging circuit; the processor communicates with the charger and is used for identifying the type of the charger and outputting an information instruction according to the type of the charger; and the controller is connected with the processor and the charging circuit and is used for controlling the charging signal to charge the battery through different charging paths in the charging circuit according to the information instruction. According to the charging system and method, target of being simultaneously compatible with two charging schemes can be achieved through identifying the type of the charger and controlling charging through different charging paths, and free selection of the charger is achieved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging system and method. Background technique [0002] With the popularization of smart phones and the increasing demand of users for the battery life of mobile phones, limited by the fact that lithium battery technology cannot make a breakthrough and increase the energy density, smart phone battery fast charging technology has been rapidly popularized. The current fast charging The output voltage of the technical charger is no longer fixed, but a controlled variable voltage value. At the beginning of charging, the host and the charger communicate and match. After the handshake is successful, the charger outputs a fixed voltage according to specific preset conditions. Then start charging. [0003] Currently, there are two main fast charging schemes: 1 high-voltage charging scheme (5V ~ 20V) and 2 low-voltage direct charging scheme (below 5V). The two schemes need to match ...
