Abstract

一种终端设备的供电电路，该供电电路包括升压电路(300)、电池芯片(100)和控制器，其中，电池芯片(100)用于将电池的输出电压提供给负载；升压电路(300)的输入端连接电池的正极，升压电路的输出端连接负载；升压电路(300)用于将输入的电压进行升压后输出；控制器，用于当采样温度小于预设温度值和/或电池的输出电压小于第一预设电压值时，控制升压电路工作且控制电池芯片停止为负载供电；当升压电路的输出电压小于升压电路的输入电压时，控制电池芯片和升压电路同时为负载供电。该方案可以在温度较低和/或电池输出电压较低时，将电池的输出电压升高，并且，当终端存在较大脉冲电流，拉低升压电路(300)的输出电压时，能够控制电池芯片和升压电路均为负载供电，增加供电电流。
