Battery Second Use Offsets Electric Vehicle Expenses, Improves Grid Stability

Save on your hotel -

Plug-in electric vehicles (PEVs) have the potential to dramatically drive down consumption of carbon-based fuels and reduce greenhouse gas emissions, but the relatively high price of these vehicles — due in large part to the cost of batteries — has presented a major impediment to widespread market penetration. Researchers at the Energy Department’s National Renewable Energy Laboratory (NREL) are playing a crucial role in identifying battery second use (B2U) strategies capable of offsetting vehicle expenses while improving utility grid stability.
