Abstract
A circuit and method for switching a charging mode are provided. The circuit for switching a charging mode, is coupled to a cell and externally coupled to a quick-charging adapter, and includes: a switch circuit, configured to connect the charging terminal and the cell terminal if a connection instruction is received from the first controlled terminal, such that the quick-charging adapter charges the cell via the switch circuit; a switching assembly, configured to receive a switching instruction from the controlled terminal; a first controller, configured to: receive a charging instruction, receive a quick-charging instruction at the first data terminal via the data interface terminal, and send the connection instruction from the third controlling terminal if the charging instruction and the quick-charging instruction are received; and a second controller, configured to send the charging instruction to the first controller if an insertion of the quick-charging adapter is detected.
