Abstract 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.
This characteristic makes them very popular in devices with high usage frequency. No memory effect: Unlike nickel-cadmium batteries, NiMH batteries are not affected by the memory effect, allowing users to charge them at any time without waiting for a complete discharge.
Application note NiMH and NiCd battery management To allow the high performance of battery packs using high-capacity rechargeable cells to be fully exploited, Philips has developed a range of highly integrated single-chip battery management circuits which safely control fast charging and indicate the state of charge of NiMH or NiCd batteries.
As shown in Figure I0 and Figure 11, the charge/discharge profiles of NiMH batteries vary too much with load, temperature and age to allow measurement of the terminal voltage as a means of determining the remaining energy for state-of- charge indication.
Electrolyte: The electrolyte in NiMH batteries is typically an alkaline solution, such as potassium hydroxide (KOH). This battery electrolyte has good ionic conductivity and enhances the overall performance of the battery. The operating principle of NiMH batteries is based on electrochemical reactions.
Wide temperature application range: The operating temperature range of NiMH batteries is usually between -30°C and 55°C, enabling stable performance in various environments. Disadvantages: Despite many advantages, NiMH batteries have some disadvantages:
