Extra Throughput versus Days Lost in load-shifting V2G services: Influence of dominant degradation mechanism

Hamidreza Movahedi, Sravan Pannala, Jason Siegel +3

Electric vehicle (EV) batteries are often underutilized. Vehicle-to-grid (V2G) services can tap into this unused potential, but increased battery usage may lead to more degradation…
