| Popis: | The use of Nickel-Metal Hydride (Ni-MH) batteries for traction application in electric and hybrid vehicles is on the rise. High-rate charge/discharge characteristics are important parameters for electric vehicle applications. The ability to reduce charging time is essential in these traction applications. In this paper, the performance of assembled Ni-MH batteries (1.2 V, 0.5 Ah specimen cells) when subjected to different charging rates is described. Changes in battery voltage during charging were monitored with a particular emphasis on the quest for fast recharge characteristics. The charging curves reveal the formation of different types of phases. Hydrogen evolution resulted in flat charge profile after certain amount of overcharging. The changes in discharge level after different rates of charging are insignificant. This paper describes the fast rechargeability of assembled Ni-MH cells under various fast-charge regimes. � 2009 International Association for Hydrogen Energy. |
