Abstract

Abstract– The management of end-of-life lithium-ion batteries from electric vehicles represents a technical and environmental challenge. A significant number of these batteries are prematurely discarded due to partial failures, even though many of their cells remain in acceptable operating conditions. In this context, second-life battery utilization emerges as an alternative aligned with circular economy principles and energy sustainability. In this paper, we present guidelines for the implementation of a specialized laboratory for second-life batteries, focused on the diagnosis, classification, rehabilitation, and assembly of new battery packs using reusable cells. The technical foundations for battery characterisation are described, along with the required equipment, tools, and instruments. In addition, the safety measures needed to mitigate electrical, thermal, and chemical risks associated with battery handling are outlined. The operational workflow, laboratory zoning, and a proposal for meeting laboratory requirements through appropriate equipment and protection systems are also presented. The proposed laboratory model provides a replicable framework for the technological validation of battery reuse processes in controlled environments, contributing to environmental impact reduction and the development of sustainable energy solutions.
