Method and device for charging in multiple modes through driving switch by battery

Abstract

The invention provides a method for charging in multiple modes through driving a charging switch by a battery, wherein the battery is utilized to drive the charging switch to prevent a human body from having an accident because of touching by mistake; adaptive charging modes can be switched according to the different states of the battery and different charging prompts can be given aiming at the different charging modes by utilizing a conventional electronic component; and a plurality of charging modes including a trickle charging mode and a constant-current and constant-voltage charging mode, a timing mode, and a function of protecting the overheating and the serious low voltage of the battery and the like under conditions of low-temperature and low-voltage charging are integrated into a whole. The invention also provides a device using the method, which has the advantage of high-precision standard charging of the battery and prevention of accidents of spontaneous combustion or explosion and the like of the batteery.

Description

technical field [0001] The invention belongs to the field of battery charging, and in particular relates to a multi-mode charging method and device for a battery-driven charging switch. Background technique [0002] With the development of the current society, all kinds of electronic instruments and equipment are mainly portable, and electronic equipment with various functions may be used anytime and anywhere, so the battery has become a necessary part of it, and the charging method of the battery should also be used.

Problems solved by technology

There are constantly high-end battery charging devices launched on the market, and liquid crystals and LCD products are also used for charging instructions. However, these special devices and liquid crystals and LCDs require huge auxiliary circuits to be driven or executed to complete the charging management function. They are actually used as charging applications. At the same time, there are too many shortcomings in terms of material supply, cost, volume, reliability, etc. It uses a variety of unconventional electronic components to achieve multiple charging modes and give different charging prompts for different charging modes, and Most chargers cannot be charged according to whether the battery is connected, and accidents may occur if the human body touches the charging terminal by mistake
