"The bidding price of energy storage systems has fallen below 0.4 yuan/Wh, seriously deviating from the reasonable cost range." At the 2025 World Energy Storage Conference, Zeng Yuqun, chairman of CATL, pointed out bluntly. Low-price competition has led to "material and configuration reductions," which has given rise to serious quality and safety hazards.

The global energy storage industry is at a crossroads of explosive growth and safety crises. As of May 2025, there have been 167 incidents of energy storage fires or explosions worldwide. As the frequency of energy storage system usage increases, safety risks are intensifying.

The energy storage industry is rapidly expanding, but it has also buried significant hidden dangers. Over the past three years, the average price of energy storage systems has dropped by about 80%, with some bulk procurement project bid prices even falling below 0.4 yuan/Wh.

This cliff-like price drop has forced some companies to sacrifice product quality and safety performance for survival.

What is even more concerning is the phenomenon of disorderly expansion in the industry. Currently, the total number of registered energy storage companies in the country has exceeded 300,000, resulting in a mixed market situation.

Zeng Yuqun issued a warning about this: "Comprehensive marketization will accelerate industry reshuffling, and it is expected that a large number of companies will be eliminated within three years, resulting in a large number of unattended 'orphan power stations', which will bring social burdens."

Facing increasingly severe security challenges, on October 16, 2025, at the Fifth Energy Storage Safety Seminar and the National Key R&D Program project "International Lithium-ion Battery Energy Storage Safety Evaluation Key Technology Cooperation R&D" seminar held in Tianjin, the "Self-Regulatory Practice Guidelines for Container Lithium Battery Energy Storage Systems" was officially released.

This document is led by the Zhongguancun Energy Storage Industry Technology Alliance and jointly formulated by 25 leading enterprises in the industry. It is the first systematic safety baseline self-discipline specification for container lithium battery energy storage systems in the industry.

The enterprises involved in the formulation cover leading companies in all segments of the energy storage industry chain, including CATL, Eve Energy, Sungrow Power, Guoxuan High-Tech, and Penghui Energy, and have broad industry representation.

"Priority, controllable risk, green and low carbon, compatible and interconnected, quality traceable," has pointed out the direction for the design of energy storage systems.

This guide sets clear baseline requirements for system parameters, key subsystems, and components.

In response to the key issues of concern in the industry, the "Self-Discipline Practice Guidelines" have made detailed recommendations, including large-scale fire tests, fire effectiveness assessments, system reliability evaluations, information security, as well as battery thermal management and ease of maintenance.

It is worth noting that the requirements of the standards also extend to the quality management of energy storage system integration and battery production, achieving full-chain quality control from production to integration.

For users and investors of energy storage systems, the "Self-Discipline Practice Guidelines" provide an authoritative supplier selection standard.

When selecting energy storage products, customers can examine whether suppliers adhere to the five core principles of safety first, controllable risks, green and low carbon, compatibility and interoperability, and traceable quality as stipulated in the "Self-Discipline Practice Guidelines."

This document provides customers with a benchmark for measuring product quality, helping users identify which companies meet industry safety standards and which companies may sacrifice safety and quality due to low-price competition.

Energy storage companies that follow the "Self-Discipline Practice Guidelines" are more likely to provide safe, reliable, and long-lasting energy storage products, offering long-term protection for customers' investments.
