Problems solved by technology

The existing battery chargers have a simple structure, and generally implement charging control in the form of analog control, so the charging process is simple and rough, and it is difficult to achieve a win-win situation between the charging speed and the service life of the battery. The charging current will also change, so it often happens that the battery is damaged due to excessive current due to continuous charging, or the service life of the battery is reduced due to undercharging and overcharging.

Embodiment Construction

[0025] The invention will be described in detail below in conjunction with specific embodiments.

[0026] The storage battery charging and discharging control method of the present invention is mainly used for fast and safe charging of the storage battery. Considering the change of the battery power during the charging process of the battery, the threshold voltage (maximum allowable voltage) and threshold voltage (minimum allowable voltage) of the charging process are ) are different, so it is necessary to detect the terminal voltage of the battery during the charging process, and carry out effective control according to the total power of the battery, the charging state of the battery and the charging mode of the battery. Its basic structure includes an input module, a control module and other auxiliary Circuits, including voltage / current acquisition, etc.

[0027] The input module is used to realize the conversion of the external power supply and form a charging and discharg...

Abstract

The invention belongs to the technical field of intelligent charging and discharging, in particular to a battery charging and discharging control method. The scheme of the invention is optimized according to the principle of the existing charger, and the charging mode and various charging parameters can be easily changed without or only requiring a small amount of hardware modification, so as to realize fast charging of batteries with different capacities, so that the scheme can be used as a tool for further research on the best charging mode. Compared with the traditional charger, the charging performance is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent charging and discharging, and in particular relates to a charging and discharging control method for a storage battery. Background technique [0002] As a kind of electric energy storage and output equipment, batteries are widely used in various power consumption occasions and stability maintenance equipment or programs. With the development of social economy and the acceleration of the pace of life, in daily life and work, temporary power consumption and There are more and more occasions for short-term power consumption, and in practical applications, the service life and effect of batteries are not only affected by their own physical characteristics, use environment and power environment, but also by the use status, charge and discharge process The impact of the battery cannot be ignored. In the above-mentioned more and more frequent temporary short-term power consumption intervals, how to q...
