Results of a study by a team at the Hawaii Natural Energy Institute, SOEST, University of Hawaii at Manoa, suggest that the additional cycling to discharge vehicle batteries to the power grid in a vehicle-to-grid (V2G) scenario, even at constant power, is detrimental to EV battery cell performance.

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.
