Research On Intelligent Management System Of Mine Energy Storage Battery

With the rapid development of my country's new energy industry,electric energy storage technology is gradually becoming mature and gradually replacing fossil fuels.Energy supply presents the characteristics of clean,high-efficiency,and intelligent development.The conversion of multiple energy sources through electric energy is the most efficient,and electric energy is the center.It has become a general consensus for "clean,low-carbon and efficient" development in the energy sector.Important equipment such as underground locomotives,elevators,and refuge chambers in coal mines mostly use large energy storage battery packs as energy storage.However,during use,the energy storage batteries exploded with a series of overcharge and overdischarge,thermal runaway,liquid leakage,etc.This leads to a series of problems such as reduced service life and lower discharge efficiency of the battery pack,resulting in greater safety hazards and economic losses.In summary,research on energy storage battery management and control related technologies,real-time monitoring and state estimation of battery operating conditions,so that it can perform charging and discharging more reasonably,and also enable operators to grasp the battery working dynamics in time,so as to More reasonable and efficient use of energy storage power sources has certain research significance for reducing battery safety accidents.This article takes mining lead-acid batteries as the research object,summarizes and analyzes the current research status of battery management systems at home and abroad,analyzes the common problems faced by current mining energy storage batteries,and finds data to study the physical and chemical characteristics of lead-acid batteries.Electrochemical reaction and charge and discharge characteristics test,build energy storage battery model,analyze the impact of different battery parameters on its service life and battery charge state,and perform demand analysis and functional design of the battery management system based on the analysis results.The key research content of the overall design mainly includes accurate collection of battery parameters,estimation of battery state of charge,battery energy balance management,and battery safety protection.The battery management system uses STM32F107 as the main control unit,and is designed with battery voltage,temperature,current and other parameter collection modules.Data transmission and command transmission are realized through CAN communication and RS485 serial port;it is equipped with touch screen and upper computer to realize real-time display of battery status and Remote control;use BP neural network technology to estimate and model the battery parameters,sample training and simulation,to achieve the purpose of accurate estimation of battery remaining power;use Flyback converter to control battery energy balance,improve battery energy usage and charge and discharge efficiency.The test results show that the battery parameter collection error and the remaining power estimation error meet the industry requirements,and the various functions of the battery management system meet the design goals.Through the research and design of the mine-used lead-acid battery management system,this paper improves the service life and charge-discharge efficiency of the mine-used storage battery,makes the battery run in a healthier manner,and improves the safety and reliability of the battery pack.The research and development of related monitoring systems for underground power supply equipment has certain reference significance.There are 56 pictures,9 tables,and 58 references.
