NREL and partners to investigate secondary uses for electric drive vehicle batteries

Green Car Congress

The cost of Li-ion batteries currently affects the affordability of plug-in hybrid and electric vehicles (PHEV/EV) for consumers. While these PHEV/EV batteries degraded to 70%-80% of their original power/capacity are insufficient for automotive use, these aged batteries may still be useful and could be reused in other applications.
