Evaluating and Repurposing of Used Ni-MH Hybrid Batteries

This paper aims at evaluating and repurposing of the used Ni-MH hybrid batteries after their life-cycle in the hybrid electric vehicles application. This process passes through two main steps, which starts by determining the state of these batteries and analyzing their behavior during the charging and discharging cycles. The work extends to show the maximum attainable power and determines the Remaining Useful Life of the used batteries by applying non-destructive tests. The next step is to maximize the obtained power and to investigate the durability of the batteries by analyzing the degradation of the used Ni-MH batteries. In addition, the applicability of the used batteries for different load scenarios will be presented.
