Title: CHARGE/DISCHARGE CIRCUIT AND CORRESPONDING MOBILE TERMINAL
Abstract:
A charge/discharge circuit and a corresponding mobile terminal. The charge/discharge circuit comprises: a charging chip (501), arranged to provide power when connected to an external power supply; a battery connector (502), arranged to input the power provided by the charging chip to a multi-cell battery (1-N); a switching module (503), arranged to switch each cell within the multi-cell battery to connect to the battery connector in a series connection state, when the multi-cell battery is charging, and to switch each cell within the multi-cell battery to connect to the battery connector in a parallel connection state, when the multi-cell battery is not charging. The charge/discharge circuit reduces the amount of heat generation of a charging path without increasing charging time. In a case wherein heat generation is not severe, charging time may even be shortened.
