Problems solved by technology

If overcharging occurs during charging, it will affect battery life and even bring safety hazards
For example, there are currently no national mandatory or natural safety standards for products such as mobile power supplies, and there is no unified standard for mobile power products launched by various manufacturers, so safety cannot be clearly guaranteed
Another example is that the quality of some brands of mobile phones is not good enough. If the battery is overcharged, it will cause the battery to swell or even explode.

Abstract

The present invention provides a charging protection method, including: acquiring at least two charging current values; calculating the charging current change ratio according to the acquired at least two charging current values; when the charging current changing ratio is less than or equal to a preset threshold, executing Preset charge protection operation. The present invention also provides a charging protection device and an electronic cigarette. The charging protection method, device and electronic cigarette of the present invention can protect the charging equipment according to the charging current change ratio, improve the safety and reliability of charging the charging equipment, and can extend the battery life. service life.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging protection method, device and electronic cigarette. Background technique [0002] With the continuous development of science and technology, electronic devices have become an indispensable part of people's lives, and most of the devices are equipped with rechargeable batteries, such as smart phones, mobile charging treasures, digital cameras, tablet computers and other smart terminals. People's life becomes rich and colorful. These products are of a great variety and different product quality is not the same, and its biggest commonality is exactly its internal battery charge, and most producers consider compatibility, all are to use USB (Universal Serial Bus, Universal Serial Bus) interface. This may cause users to use or misuse various chargers when using different products. [0003] For different products, the charging output current is different. If overcharging...
