EV batteries today\, almost exclusively lithium-i on based\, can last about 10 years before they can no longer provide the r equired performance such as power and range. They cost heavily in both pro duction and recycling. So economically dealing with retired EV batteries i s an important topic. It is estimated that the first huge wave of EV batte ry retirement will hit in 2025\, and more retired batteries will be availa ble each year thereafter.</p>\n<p>On the other hand\, renewable energy\, s uch as solar photovoltaic (PV) and wind\, also enjoy a high rate of penetr ation. To buffer the volatile nature of the energy output of renewable ene rgy systems\, battery energy storage systems (BESSs) are frequently incorp orated to balance out the variability in power generation\, efficiently ma nage the dynamics of demand and supply\, mitigate the potential failure of the grid due to over generation\, provide power during a power outage\, a nd enable cost savings by shifting the peak use and reduce demand charge. However\, the high cost of new batteries in renewable and grid storage sys tems is a major concern for potential home and business owners.</p>\n<p>Ba tteries in EVs degrade gradually over the lifetime of the vehicle and will reach the point that it is no longer able to provide the required perform ance\, such as range and acceleration. Second-life EV batteries include no t only the batteries that are discarded from EVs due to degraded condition s\; but also in-warranty replacements\; road accidents\; test vehicle batt eries\; and unsold batteries. Second-life EV batteries\, though no longer roadworthy in the vehicle\, still have considerable capacity for renewable energy and smart grid applications where the requirement for energy and p ower density is not as stringent in vehicles.
