TS EN IEC 62933-1

TS EN IEC 62933-1 is a vocabulary standard that defines the core terminology for electrical energy storage (EES) systems. It brings together the key terms used when describing EES technology so that unit parameters, test language, planning, installation, safety, and environmental topics can be understood in a consistent way.

Shared terminology for EES systems

Electrical energy storage systems take electrical energy from a power system, store it internally, and later inject electrical power back into the electric power system. In practical engineering terms, the charge and discharge stages may involve an energy conversion step as part of the overall process. A vocabulary standard does not define product performance by itself; it creates the common language needed to discuss the technology clearly across suppliers, designers, operators, and test organisations.

Technical context covered by this standard

• Applies to grid-connected EES systems.
• Includes terms needed to define unit parameters.
• Covers terminology related to test methods, planning, and installation.
• Brings together expressions used for safety and environmental issues.
• As a terminology document, it clarifies concepts rather than imposing methods or limits.

Standards of this kind are especially useful where battery-based storage, power conversion equipment, and grid integration intersect. They help keep documentation, specifications, and technical communication aligned, which is important when the same concept may be described differently across disciplines. TS EN IEC 62933-1 serves as the foundational vocabulary for that technical area.
