Abstract | The performance and lifecycle costs of battery electric vehicles (BEVs) and hybrid electric vehicles (HEVs) are closely tied to their energy storage systems. The nickel-metal hydride (NiMH) battery has been the recent battery of choice for these vehicles because of its high specific energy and long cycle life. However, NiMH batteries are expensive, and researchers have looked for methods of extending the cycle life of less costly valve-regulated lead acid (VRLA) batteries in order to make them competitive with NiMH systems. VRAL units are also suitable for high-volume production methods, and their recyclability makes them environmentally sustainable. An improvement in their deep cycle life by a factor of three or four would make them practical for use in transportation systems. |
