The Luskin Center is developing innovative strategies to enhance plug-in-electric-vehicle (PEV) value through secondary use of PEV batteries. This includes both vehicle-to-grid power (V2G) and post-vehicle repurposing of used PEV batteries (“second life”) into stationary energy-storage appliances (B2G). These various forms of energy storage can provide mobile, emergency, and/or grid power and valuable services. Applications examined include power quality/reliability, demand-charge mitigation, utility transmission and distribution upgrade deferral, and grid regulation.
