Charging method, circuit and system of mobile power source

Abstract

The invention relates to a charging method, circuit and system of a mobile power source. The charging method of the mobile power source comprises the steps that the real-time temperature of an electric cell is acquired and compared with the preset temperature threshold value, so that detection signals which reflect the difference value between the real-time temperature and the temperature threshold value are generated; according to the detection signals, the input power and / or output power are / is adjusted based on a preset strategy until the real-time temperature is kept within the preset temperature threshold value range. According to the charging method, the acquired real-time temperature of the electric cell is acquired and compared with the preset temperature threshold value, and the input power or the output power is adjusted so that the real-time temperature can be kept within the preset temperature threshold value range when the mobile power source works at the adjusted and determined input power and the output power. Due to the fact that the temperature generated in working is limited within the preset temperature threshold value, the number of accidents such as IC chip burning-out, short circuit and battery fire outbreak caused by excessively high working temperature is reduced.

Description

technical field [0001] The present invention relates to the technical field of power supply charging, more specifically, it relates to a mobile power supply charging method, a power regulation circuit and a charging system. Background technique [0002] Mobile Power Pack (MPP), also called travel charger, is a portable charger that integrates power supply and charging functions. It can charge mobile phones, tablet computers and other digital devices anytime and anywhere. Generally, lithium batteries are used as storage. electric unit. [0003] At present, the mobile power supply on the market generally does not have the temperature control function, and the mobile power supply is mainly used for fast charging, so its power is usually high. When the mobile power supply is working in a harsh environment, it is easy to cause the working temperature to be too high. The working temperature is one of the main reasons for accidents such as IC chip burnout, circuit short circuit, a...

[0003] At present, the mobile power supply on the market generally does not have the temperature control function, and the mobile power supply is mainly used for fast charging, so its power is usually high. When the mobile power supply is working in a harsh environment, it is easy to cause the working temperature to be too high. The operating temperature is one of the main causes of accidents such as IC chip burnout, circuit short circuit, and battery fire.
