Title: Repurposing of Batteries from Electric Vehicles

Energy storage for stationary use is gaining traction both at the grid scale and distributed level. As renewable energy generation increases, energy storage is needed to compensate for the volatility of renewable over various time scales. This requires energy storage that is tailored for various energy to power (E/P) ratios. Other applications for energy storage include peak shaving, time shifting, load leveling, VAR control, frequency regulation, spinning reserves and other ancillary applications. While the need for energy storage for stationary applications is obvious, the regulations that determine the economic value of adding storage are at various stages of development. This has created a reluctance on the part of energy storage manufacturers to develop a suite of storage systems that can address the myriad of applications associated with stationary applications. Deployment of battery energy storage systems in the transportation sector is ahead of the curve with respect to the stationary space. Batteries, along with battery management systems (BMS) have been deployed for hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs) and electric vehicles (EVs). HEVs have now been deployed for 12 years, while PHEVs for 8 and EVs for 4 years. Some of the batteries are approaching end of lifemore » within the vehicle, and are ready to be taken off for recycling and disposal. Performance within a vehicle is non-negotiable in terms of miles traveled per charge, resulting in the batteries retaining a significant portion of their life. For stationary applications, the remaining energy and power of the battery can still be used by grouping together a few of these batteries. This enables getting the most of these batteries, while ensuring that performance is not compromised in either the automotive or stationary applications. This work summarizes the opportunities for such re-purposing of automotive batteries, along with the advantages and limitations« less
