PNNL study finds that PHEVs and BEVs could serve as feasible resource to offset grid imbalances caused by integration of large amounts of intermittent wind generation

Green Car Congress

trafficThis scenario is highly desirable to automotive manufacturers, who harbor great concerns about battery warranty if vehicle-to-grid discharging is allowed. V2GFull varies not only the charging of the vehicle battery, but also can vary the discharging of the battery back into the power grid.

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.
