TS EN IEC 62933-1
Electrical energy storage (EES) systems - Part 1: Vocabulary
IEC 62933-1:2024 defines terms applicable to electrical energy storage (EES) systems including terms necessary for the definition of unit parameters, test methods, planning, installation, operation, environmental and safety issues. This terminology document is applicable to grid-connected systems able to extract electrical energy from an electric power system, store energy internally, and provide electrical energy to an electric power system. The step for charging and discharging an EES system can comprise an energy conversion. This second edition cancels and replaces the first edition published in 2018. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition (with revision) of the entries developed during the edition 1 stability period and, therefore, included only in other IEC 62933 parts; b) addition of the entries developed during the edition 1 stability period and published in this document for the first time; c) complete revision of the entries already present in edition 1.

About This Item
TS EN IEC 62933-1 is the vocabulary standard that establishes the common terminology for electrical energy storage systems. It gathers the terms used in EES technology so that unit parameters, test methods, planning, installation, operation, and environmental and safety topics can be discussed consistently. In general technical terms, electrical energy storage is a key enabling technology for grid balancing, integration of variable renewable generation, power quality support, and supply flexibility.
How EES terminology is organised
This document applies to grid-connected systems that can take electrical energy from an electric power system, store it internally, and later deliver electrical energy back to that system. Charging and discharging may include an energy conversion step, which is why the vocabulary needs to distinguish storage, conversion, and system integration concepts. In practical engineering use, those distinctions matter when describing performance, efficiency, operating behaviour, and the overall architecture of an EES installation.
