Retired battery energy storage case study

What is the evaluation of retired batteries?

The evaluation of retired batteries mainly focuses on the current state of the battery pack, which is used to decide whether the battery pack can be reused or further dismantled. The evaluation of the battery pack is divided into three parts: appearance inspection, electrical performance testing and final inspection.

How profitable are retired batteries?

Moreover, results suggest that settling for a lower purchase price for retired batteries would make the investment as profitable as new batteries at the current market price. On this benchmark, values of retired batteries from 4- and 10-year-old disposed of vehicles have been estimated to be 26% and 15% of original battery price.

Are EV batteries good candidates for reusing retired batteries?

Overall, principally EV batteries are great candidates for lower demanding applications in power systems. However, with EVs being increasingly adopted, the huge amount of retired battery waste will surplus the limited demand for grid service applications as the best current candidate for reusing retired batteries.

How can a retired battery treatment be optimized economically and environmentally?

Based on the process-based life cycle assessment method, we present a strategy to optimize pathways of retired battery treatments economically and environmentally. The strategy is applied to various reuse scenarios with capacity configurations, including energy storage systems, communication base stations, and low-speed vehicles.

Can EV batteries be reused in stationary storage applications?

As stated previously, the combined techno-economic benefits like projected future business revenues and RUL extension by accurate SOH estimation methods are expected to tackle the growing number of retired batteries from EVs by increasing the feasibility of their reuse in stationary storage applications. Not Applicable.

Why is B2U obstructing the use of retired batteries?

Additionally, multiple concerns such as economic ambiguity about B2U being a cost-effective solution for customers; liability associated with SLBs; and a lack of data on the effectiveness of batteries in their first and second lives create roadblocks that obstruct the usage of retired batteries .
