Investigation of Remaining Capacity Estimation Method for Nickel-Hydrogen Secondary Battery

Abstract

We are developing a LED small plant cultivation system using natural energy. The data from the Meteorological Agency is used to perform optimal energy management. A Nickel-Hydrogen rechargeable battery is used for the battery. In order to perform optimum energy management, it is necessary to accurately know the remaining charge capacity when energy is used. In this report, we will report the experimental results of the characteristics of the closed circuit voltage and the open circuit voltage of battery terminals.
