Performance analysis of nickel metal hydride (NiMH) rechargeable battery using Matlab/Simulink

This research presents the performance analysis of Nickel Metal Hydride (NiMH) rechargeable battery using MATLAB/Simulink. Nickel Metal hydride (NiMH) batteries are used as hydrogen storage material with high hydrogen volumetric capacity and reversible hydrogen absorption/desorption reactions. The study helps contribute to the lingering research gap regarding the NiMH battery. Recent research works conducted on NiMH battery cover areas such as the battery capacity and its memory effect. This research work addresses the charge/discharge characteristics and the battery voltage. The methodology employs the use of a generic battery model which is modeled using the Simulink library materials. Simulation using nickel hydrogen battery model thus makes it possible to analyze the characteristics of chargeability and discharge ability. The result showed that the battery has a nominal voltage of 200 volt. The machine runs at 120 rad/s and the charge and discharge characteristics showed that the battery is least affected by its memory.
