Abstract

A method for controlling a plurality of batteries and an electronic device for implementing the method are provided. An electronic device includes a housing having first and second batteries, a power management integrated circuit, a battery charging circuit, and a booster circuit. The housing also includes a first switch connected to the first battery, a second switch connected to the second battery, and a control circuit. The control circuit provides one of the following states: a first state in which the first battery is connected to the PMIC and the battery charging circuit, a second state in which the first battery is connected to the booster circuit and the battery charging circuit, and a state in which the first battery forms an open circuit. The third state, the fourth state in which the second battery is connected to the PMIC and the battery charging circuit, the fifth state in which the second battery is connected to the booster circuit and the battery charging circuit, and the sixth state in which the second battery forms an open circuit.

Description

technical field [0001] Various embodiments relate to a method for controlling a plurality of batteries and an electronic device therefor. Background technique [0002] With the development of digital technology in recent years, various electronic devices capable of communicating and processing personal information while they are in motion (such as mobile communication terminals, personal digital assistants (PDAs), electronic schedulers, smart phones, etc.) have been released. and / or tablet personal computer (PC)). Since the purpose of such an electronic device is portability, a battery (for example, a removable battery) is used as a power supply device. The battery can output voltage and current suitable for each electronic device. [0003] The electronic device supports a battery or supports a form of an auxiliary battery. The electronic device may not independently monitor the charge level and battery status of the auxiliary battery. For example, when multiple batterie...
