- With the development of technology and the growing problems of environmental protection and energy shortage, renewable and clean energy power generation is receiving more and more attention. However, due to the randomness and volatility of renewable energy, it has a certain impact on the power grid. Hence, efficient energy storage technology is urgently needed to solve this problem. Therefore, battery energy storage system (BESS) has become one of the hot topic for research. Currently most of the electric energy is being stored in battery storage system. The main tasks of this paper are as follows: firstly, introduce and analyze lithium ion battery storage system and its characteristics, especially the operating temperature ranges of the optimal charging and discharging curves. Secondly, analyze the charge and discharge curve of lithium ion battery in the range of minus 40 degrees Celsius to plus 40 degrees Celsius by simulating temperature dependence model in MATLAB. And through observation, it was found that Lithium Ion Battery has better charge-discharge properties during operation in the range of zero degrees to 40 degrees Celsius. Thirdly, a temperature controlled topological method is proposed to make the lithium ion battery to operate in three temperature ranges respectively: 10 to 20 degrees Celsius, 20 to 30 degrees Celsius and 30 to 40 degrees Celsius. Based on MATLAB and GUI, a program for comparing the charge and discharge performance of lithium-ion battery in different temperature ranges was developed. The conclusions of this paper were verified by the analysis of charging and discharging in these temperature ranges. Finally, an android application is designed to upload battery voltage, temperature and circuit control status in real time. In conclusion, this paper provides some technical support for charging and discharging application of lithium battery energy storage system.
