Abstract

A portable communication device, according to various embodiments of the present disclosure, may include: a battery pack; a power dissipation element disposed outside the battery pack; a detecting circuit configured to detect the state of the battery pack; and at least one of first switches that are connected to the battery pack and the detecting circuit, wherein the detecting circuit is configured to control at least one of the first switches to: electrically disconnect the power dissipation element from the battery pack when the state of the battery pack does not satisfy a specified condition; and electrically connect the power dissipation element to the battery pack when the state of the battery pack satisfies the specified condition.

Description

technical field [0001] The present disclosure generally relates to a circuit for controlling power output from a battery pack, and also relates to a battery pack. Background technique [0002] A battery cell may include a positive electrode, a negative electrode, an electrolyte, and a separator, and may perform charge and discharge operations by movement of lithium ions between the positive electrode and the negative electrode. The separator is used to separate the positive electrode and the negative electrode from each other, and is used for movement of lithium ions. In the case of lithium batteries, the state of lithium ions can differ between positive and negative electrodes. Due to the different states, a potential difference can occur between the positive and negative electrodes, allowing electrons to move and thus carry out the discharge process. Thus, for example, current can flow from the aluminum foil of the positive electrode collector plate to the copper foil of...
