Mini Grids in Puerto Rico using Repurposed NiMH Batteries

This invited presentation by Dr. Smotkin was given at the HOMER International Microgrid Conference hosted by HOMER Energy in Cambridge, MA. Dr. Smotkin explains the memory effect of Toyota nickel metal hydride batteries extracted from end-of-life vehicles. Dr. Smotkin describes how these spent traction batteries are reconditioned for use in photovoltaic solar energy conversion and storage systems.
