DIN VDE V 0510-500:2025-11 - Draft

This document describes various methods for deactivating lithium-ion cells, modules, and batteries, in particular the requirements for the discharge process of electrochemical energy storage devices. The aim is to render cells, modules, or batteries into a state in which they no longer possess any significant amount of energy that can be converted into electrical energy. Furthermore, it describes the specific requirements in order to ensure that the cells, modules, or batteries no longer pose any specific electrical hazards. This document does not cover other battery-specific hazards such as: - fire and explosion; - hazardous substances (for example, gaseous, liquid, dusty, fibrous); - effects of components containing explosives (such as "pyro safety switch"). This document is primarily focused on lithium-ion technology, although its application to other technologies is not excluded. This document provides, among other things, guidance on implementing the basic principles of electrical safety (for example, five safety rules according to DIN EN 50110-1, DIN VDE 0105-100, subclause 6.2) and, if correctly applied, can reduce the impact of electrical hazards.
