Abstract

A wearable device charging control method comprises the steps: sampling the real-time operation temperature of a main chip; judging whether the real-time running temperature of the main chip meets anallowable charging condition or not; if yes, conducting at least one charging branch between the battery and the charger according to the real-time operation temperature of the main chip to form a charging path, wherein the higher the real-time operation temperature of the main chip is, the smaller the resistance value of the gated charging path is. A wearable device is also provided. According tothe invention, the allowable charging condition of the battery is judged by using the real-time running temperature of the main chip; a charging branch between the battery and the charger is conducted according to the real-time operation temperature of the main chip to form a charging path; the battery is charged only at the safe charging temperature, and a control mode that the higher the real-time operation temperature of the main chip is, the larger the charging current is formed at the safe charging temperature, so that the working performance of the battery in a complete working temperature interval is fully exerted, the battery under a low-temperature charging condition is protected, the performance is reliable, and the hardware cost is saved.

Description

technical field [0001] The invention belongs to the technical field of electronic equipment, and in particular relates to a charging control method of a wearable device and a wearable device adopting the charging control method. Background technique [0002] The charging protection of traditional electronic equipment usually configures the charging voltage and charging current according to the battery temperature: when the battery temperature is in a different range, neither the charging voltage nor the charging current can exceed the set threshold, so as to achieve the purpose of protecting the battery. In the prior art, a charging chip (charger IC) has been developed based on this principle, which integrates charging protection and battery temperature detection into the same chip. [0003] Among all kinds of electronic devices, designers of wearable devices face unique challenges to provide long battery life and an intuitive user interface, all integrated in a sufficiently...
