The rapid growth of world wide industrial development has resulted in soaring energy usage, which has resulted in global warming and environmental pollution. As the problem of depletion of fossil fuels and rising oil prices emerges from society, developed countries in the US, Japan and Europe are pushing for green growth policy at the national level.
The energy storage system(ESS) can save the energy that is used and the remaining power in the system, and it can increase the utilization efficiency of the energy by supplying the system when the power is needed. It is possible to prepare for the unstable power supply of new and renewable energy sources and to play a role as demand manager through load leveling.
In this paper, we have studied battery characteristics and charge algorithm to develop solar energy - linked energy storage system. Simulation was carried out to apply the battery management system which monitors the status of the battery in real time and controls the battery to be used under optimal conditions. The SOC of the battery and the replacement time of the battery based on the simulation are then predicted and maintained And to secure the reliability and safety of the system. As a result of analysis of the discharge curves according to the current size of the lithium ion battery, it was found that the discharge capacity increased as the current size was smaller, the internal electrochemical characteristics were increased with increasing temperature, and the discharge capacity was increased. In addition, through the application of the charging algorithm, we were able to analyze characteristics such as controlling the over-current and improving the charging efficiency by precisely controlling the charging time.
As a result of this study, it is expected that efficient operation and development of solar energy storage system will be possible through characteristics such as improvement of battery characteristics and charging efficiency according to charging algorithm.
