Abstract |
As the demand and field of use for lead acid batteries increases, interest in test methods and test facilities that consider the characteristics and safety of batteries is also increasing. Basically, there are problems related to the charging time, self-discharge, charging and discharging characteristics, and energy density (low energy density) of lead acid batteries. The charging and discharging characteristics of lead acid batteries are stable within a certain range, but excessive discharging or overcharging reduces performance and shortens lifespan, and repeated charging and discharging has a significant impact on changes in the characteristics and lifespan of the battery. When charging a lead acid battery, conditions such as voltage, current, time, and temperature are often within the range set by the battery specifications. And the discharge operation is directly related to the usage time and performance of the lead acid battery and is evaluated as its own performance factor. Therefore, due to the complex characteristics of lead acid batteries due to charging and discharging, research on optimization and management is needed in various ways. Therefore, in this paper, we built a test facility that can analyze the charging and discharging characteristics of lead acid batteries. And using these test facilities, we aim to promote the safety of lead-acid batteries by analyzing their operation and analysis through charging and discharging experiments. |
