Retired battery storage case study

Can retired batteries be used as energy storage batteries?

In 2016, Nissan launched The Mobility House project, applying 280 retired batteries from Nissan Leaf to the xStorage Buildings System as energy storage batteries . In 2017, Daimler launched a demonstration project, in which 1000 retired batteries from Smart Fortwo were repurposed in grid-side ESSs .

What type of batteries are used in a retired battery study?

The retired batteries employed in this study consist of two types of lithium iron phosphate (LFP) batteries from Gotion Hi-Tech, specifically the IFP2265146-23Ah and IFR32135-15.5Ah models.

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.

Do retired EV batteries have a high residual capacity?

Retired EV batteries still have high residual capacity, and these batteries, after re-diagnosis, sorting, and reorganization, may be applied in scenarios with more moderate working conditions [8, 9] such as grid energy storage, to realize the gradient utilization of power batteries .

Are lithium-ion batteries retired from EVS practical?

The contribution of this paper is the practical analysis of lithium-ion batteries retired from EVs of about 261.3 kWh; detailed analysis of the cost of acquisition, disassembly, reassembly and secondary use; and finally the analysis based on the actual operating conditions of photovoltaic (PV)-load grid.

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.
