Electronic device and method for monitoring battery module of the same
First Claim
1. A method for monitoring a battery module, the battery module applied to an electronic device, the method comprising:
- reading a reported battery capacity and a battery temperature of the battery module;
determining whether the reported battery capacity is smaller than a minimum capacity required for device operations;
when the reported battery capacity is lower than the minimum capacity, determining whether the battery temperature is lower than a minimum temperature;
in response to determining that the battery temperature is lower than the minimum temperature and the reported battery capacity is lower than the minimum capacity, generating, by a controller, a fake battery capacity and operating the electronic device according to the fake battery capacity, wherein the fake battery capacity is higher than the minimum capacity; and
when the reported battery capacity is higher than the minimum capacity or the battery temperature is higher than the minimum temperature, operating the electronic device according to the reported battery capacity.

Abstract
An electronic device including a control unit, an embedded controller and a battery module is provided. During a booting procedure of the electronic device, the embedded controller reads a reported battery capacity and a battery temperature of the battery module. The embedded controller determines whether the reported battery capacity is lower than a minimum capacity, and further determines whether the battery temperature is lower than a minimum temperature when the reported battery capacity is lower than the minimum capacity. When the reported capacity is lower than the minimum capacity and the battery temperature is also lower than the minimum temperature, the embedded controller generates a fake battery capacity, according to which an operating system of the electronic device performs various operations. In this application, the battery module of the electronic device remains working even when the electronic device is in a low-temperature and low-battery activation environment.
