Energy storage battery retirement management

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.

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.

What can a retired battery do?

Besides ESSs, retired batteries possess a diverse range of potential applications 18, spanning various fields, such as communication base stations (CBSs) 14, 17 and low-speed vehicles (LSVs) 19, 20.

Can retired batteries be used in PV-containing grids?

In addition, retired batteries can not only be used to consume renewable energy, but also provide services such as frequency regulation for the grid to better utilize its performance. This paper analyzes the economics of retired batteries from EVs for use in PV-containing grids.

What is a battery energy storage system?

Battery energy storage systems (BESS) Electrochemical methods, primarily using batteries and capacitors, can store electrical energy. Batteries are considered to be well-established energy storage technologies that include notable characteristics such as high energy densities and elevated voltages .

What is the SoH of retired EV batteries?

In this paper, the SOH of retired EV batteries is set at 70%, 80%, and 90%, while the SOH at the EOL stage is set at 90%, 80%, 70%, 60%, 50%, and 40%. This stratification by 10% intervals allows for a detailed observation of aging processes, enhances the clarity of the data, and aids in the visual representation of findings.
