GB/T 43962.1-2024System integration of power battery digital workshop - Part 1: General requirements (English PDF)

Foreword

This document was issued on 25 April 2024 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 November 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 43962.1-2024 is Part 1 of the Chinese series on the system integration of power battery digital workshops. A power battery line is one of the most heavily instrumented factories in China: electrode coating, winding or stacking, formation and grading all generate process data that has to be tied to a single cell identity and kept for the life of the battery, which means the workshop is an integration problem before it is a manufacturing one. Part 1 sets the general requirements. It defines the integration architecture and its layering and the process flow through it, then the basic management requirements at the resource layer including personnel, equipment and the data dictionary, the technical requirements at the facility layer, the technical requirements at the platform layer, the requirements on the service layer, and the data integration requirements that hold the layers together. It took effect on 1 November 2024.

This document specifies the integration architecture, basic management requirements

for the resource layer, technical requirements for the facility layer, technical

requirements for the platform layer, service layer requirements, and data integration

requirements of the power battery digital workshop integration.

This document applies to the planning, construction, and acceptance of the power

battery digital workshop integration. It is also a reference for digital workshop

integration for energy storage batteries (including future battery types, such as semi-

solid and solid-state).
