An intelligent battery charging and discharging control system and method

Abstract

The invention relates to an intelligent battery charging and discharging control system and method. The system comprises a battery pack state monitoring and switching module, a charging module, a discharging module, an alarm apparatus and a touch display screen which all are connected with a master control module, wherein the charging module and the discharging module are connected with the battery pack state monitoring and switching module. According to the intelligent battery charging and discharging control system and method, the quantity of battery packs can be flexibly increased and reduced, the battery packs are automatically matched for charging according to different charging power supplies on the premise of the security and the stability, the combination forms of currently arranged battery packs are intelligently adjusted to meet the requirements of different electricity loads, the charging and discharging ratio and series-parallel combination of discharging battery packs are intelligently controlled when the charging process and the discharging process are simultaneously carried out, and the condition that different charging power supplies and different electricity loads simultaneously carry out charging and discharging efficiently is met in a manner of optimizing and adjusting the states of the battery packs.

Description

technical field [0001] The invention belongs to the technical field of charge and discharge intelligent control, and in particular relates to an intelligent battery charge and discharge control system and method. Background technique [0002] The existing charging devices, discharging devices or charging and discharging devices can already meet the basic charging and discharging needs, but most of them are equipped with a fixed number of batteries, which cannot flexibly increase or decrease the number of battery packs, provide a certain amount of power, and output voltage , the current is limited, or changes within a very narrow range, it cannot automatically match and charge the battery pack according to different charging sources, and it cannot intelligently adjust the combination of the currently configured battery pack to meet the requirements of different power loads. When the charging and discharging process is carried out simultaneously, it can only provide a simple c...

[0002] The existing charging devices, discharging devices or charging and discharging devices can already meet the basic charging and discharging needs, but most of them are equipped with a fixed number of batteries, which cannot flexibly increase or decrease the number of battery packs, provide a certain amount of power, and output voltage , the current is limited, or changes within a very narrow range, it cannot automatically match and charge the battery pack according to different charging sources, and it cannot intelligently adjust the combination of the currently configured battery pack to meet the requirements of different power loads. When the charging and discharging process is carried out simultaneously, it can only provide a simple charging and discharging state, and fails to intelligently control the charging and discharging ratio and the series-parallel combination of the discharging battery pack to meet different charging power sources and different uses in an optimal way. Efficiently charge and discharge electrical loads at the same time
