GB/T 44133-2024Technical guide for smart electrochemical energy storage station (English PDF)

Foreword

This document was issued on 28 May 2024 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 December 2024.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 44133-2024 is the technical guide for smart electrochemical energy storage stations. A grid battery is unattended, contains tens of thousands of cells, and gives very little warning before a cell goes into thermal runaway; the case for instrumenting it heavily is that the only cheap moment to detect a failing cell is months before it fails. The standard sets the general requirements and the system architecture, then the intelligent operation and maintenance, the intelligent inspection and repair, the safety management, and the intelligent operation of the station - covering the monitoring, the diagnosis and prediction of cell and system state, the automated response and the dispatch interface - with an informative annex giving the overall architecture of a smart storage station. It took effect on 1 December 2024.

This document specifies the technical requirements for the system architecture,

intelligent running and maintenance, intelligent inspection and repair, safety

management, and intelligent operation of smart electrochemical energy storage power

stations.

This document applies to the construction and operation of smart electrochemical

energy storage power stations.

3 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

3.1

smart electrochemical energy storage station

4.4 Smart electrochemical energy storage stations shall be provided with digital twin

models to achieve the integration and sharing of production data and management data.

4.5 Smart electrochemical energy storage stations shall be equipped with a production

operation management system that integrates operation and maintenance resource

monitoring and control, operation and maintenance work order processing, operation

and maintenance reports, operation and maintenance knowledge base, operation and

maintenance display center, marketing management, transaction management, and

customer management.

4.6 Smart electrochemical energy storage stations shall meet the following cyber

security requirements during the design, running, maintenance and operation phases:

a) During the design phase, minimize the external interface exposure of various

intelligent equipment in the power station, and the external interface supports

access control mechanism based on authentication and authorization;

b) During the running phase, use information encryption technology when

transmitting and storing sensitive data and personal data. The situation

awareness platform in the power station automatically collects and analyzes

operation data information, and automatically perceives and predicts security

risks;

c) During the maintenance phase, timely repair vulnerabilities in intelligent

equipment and systems, support automatic software reinforcement and upgrade,

and automatically perform digital signature verification before upgrading;

d) During the operation phase, support automatic detection of new software

versions and prompt for upgrades, automatically verify network security

configurations and generate risk assessment reports.

4.7 Smart electrochemical energy storage stations should have the capabilities of

autonomous learning, automatic optimization, and iterative evolution.
