Under the wave of the global rail transit industry's accelerated transition to electrification, the safety performance of battery power systems has become a core factor restricting the high-quality development of the industry. The "Safety Design Specification for Rail Transit Battery Power Systems T/CIET 1206—2025" group standard, released in April 2025, has been in effect for nearly three months and is reshaping the industry's development pattern with a systematic safety framework. As a core participating enterprise, Qualtech, with its profound technical accumulation and continuous innovation capabilities, has provided key support for the implementation of this standard, propelling the safety design of rail transit battery power systems into a new stage of development.
This document addresses the issues existing in the design process of power battery systems for rail transit and proposes systematic design norms, aiming to reduce the risk of battery system failures and enhance the overall safety of rail transit. The standard covers the application environment, basic requirements, design requirements, safety testing and verification, as well as production and maintenance safety of power battery systems used in rail transit vehicles. By implementing this standard, enterprises can obtain clear guidance for research and development and production, effectively curb the disorderly market competition caused by the lack of standards, and provide solid safety guarantees for passengers' travel and the operations of staff by improving the overall safety performance of products.
Qualtech is dedicated to the research and development, design, production and sales of core products such as BMS for new energy vehicles and 4S+C for energy storage. At the same time, it provides overall solutions and implementation services for energy storage system integration, photovoltaic-storage-charging integrated systems, smart energy management systems, and microgrid systems for various scenarios. As an innovative enterprise in the energy field, the company not only continuously promotes technological innovation but also regards the improvement of safety standards as an important mission. It actively participates in and effectively promotes the formulation of multiple industry and group standards.
In addition to participating in the formulation of the "Safety Design Specifications for Power Battery Systems in Rail Transit T/CIET 1206—2025", Qualtech has also been deeply involved in the drafting and formulation of many important standards such as "Technical Requirements for Thermal Runaway Warning and Protection of Ion Batteries T/CEPPC 25—2024", "Technical Guidelines for Intelligent Diagnosis of Electrochemical Energy Storage Power Stations T/CEPPC 24—2024", "Technical Specifications for Energy Management Systems of Electrochemical Energy Storage Power Stations T/CIAPS 0034—2024", and "Technical Requirements for Power Lithium-ion Batteries for Ships T/DZJN 340—2024". The successful release of these standards fully demonstrates Qualtech's profound strength and professional background in the energy field, and also reflects the high recognition of Qualtech by the industry.
Looking to the future, Qualtech will continue to stand at the forefront of technological innovation, continuously injecting strong impetus into the standardization and healthy development of the industry, and helping the industry to keep moving forward.
