Abstract

The charging control method of the wearable device includes sampling the real-time operating temperature of the main chip; judging whether the real-time operating temperature of the main chip meets the allowable charging condition; if so, conducting at least one charging branch between the battery and the charger according to the real-time operating temperature of the main chip to form a charging path; wherein, the higher the real-time operating temperature of the main chip is, the smaller the resistance value of the gated charging path is. A wearable device is also provided. The invention uses the real-time operating temperature of the main chip to judge the allowable charging conditions of the battery, and conducts the charging branch between the battery and the charger according to the real-time operating temperature of the main chip to form a charging path. Under the safe charging temperature, the higher the real-time operating temperature of the main chip, the greater the charging current control method, fully exerting the working performance of the battery in the full working temperature range and protecting the battery under low temperature charging conditions, reliable performance and saving hardware cost.

Description

Wearable device charging control method and wearable device technical field The present invention belongs to the technical field of electronic equipment, particularly a kind of wearable device charging control method, and a A wearable device using this charging control method. Background technique [0002] The charging protection of traditional electronic equipment is usually based on the battery temperature to configure the charging voltage and charging current: when When the temperature of the battery is in different ranges, the charging voltage and charging current cannot exceed the set threshold, so as to achieve the protection purpose of the battery. In the prior art, a charger IC is developed based on this principle, which integrates charging protection and battery Temperature detection is integrated in the same chip. [0003] Among various electronic devices, designers of wearable devices face unique challenges to provide long battery life and an intuitive us...
