The mandatory national standard "lithium storage battery for electric energy storage systems and safety requirements for battery packs", which was officially implemented in August 2025, marks that the energy storage industry officially bid farewell to "savage growth". This is the first mandatory national standard for energy storage battery safety, filling the gap in the field of energy storage battery safety strong standard in our country. It is applicable to lithium a galvanic battery for electric energy storage systems with rated energy usually above 100kWh, covering telecom, photovoltaic system, household and large energy storage and other application scenarios.

What requirements does this strong standard put forward to the PACK factory?

In the determination of the thermal diffusion test of the battery pack system, the strong standard requires that no thermal diffusion occurs between the batteries, no external flame occurs in the battery pack system, and no rupture occurs in the shell of the battery pack system. For prefabricated cabin-type lithium ion battery energy storage system, the first national mandatory technical specification requires no fire, no explosion, and no triggering of thermal runaway of other battery modules..

behind these definable targets is a comprehensive test of PACK system integration capabilities. Thermal diffusion does not spread, and collaborative design of heat barrier material, pressure relief channel and module structure layout is required; The shell is not broken, and precise matching of structural strength simulation and material selection is required; Thermal runaway of other modules is not triggered, it requires the BMS temperature monitoring strategy and the fast response of the active equalization system.

At the same time, the newly implemented "design standard of electrochemical energy storage power station" in April, 2026 systematically upgraded the safety requirements of energy storage power station, making it clear that the spacing between prefabricated cabins is not less than 3 meters, the core idea of hard constraints such as no more than 50MWh in each fire zone is to shift from "fire fighting afterwards" to "prevention and control in advance and precise suppression".

This means that when energy storage equipment manufacturers choose PACK partners, they need to examine whether they can do battery PACK or not, but whether they can do security systems ".

Dongguan Juneng New Energy Technology Co., Ltd. has accumulated more than 10 years of experience in battery pack structure design, heat management and BMS development, and has accumulated practical projects in the field of energy storage. The company's 1000W portable home energy storage system for European market supports 110V/220V dual voltage pure sine wave output. In the design of BMS, the BMS of energy storage battery is linked with EMS to participate in the overall energy scheduling. Thermal runaway in aerogel insulation technologyIn terms of protection scheme, energy gathering New Energy Co-optimizes heat barrier material with pressure relief channel design, module structure layout, and BMS temperature monitoring strategy to form a complete PACK security system scheme.

With the implementation of many mandatory national standards in the energy storage industry, the driving force of the industry is changing from "mandatory allocation and storage" to "market-oriented storage". Enterprises no longer simply compete for capacity scale and delivery speed, and focus more on comprehensive cost optimization and safe and efficient operation management throughout the life cycle.. For energy storage equipment manufacturers, select one that can provide specific solutions on security system integration. PACK partners, is becoming the key to whether the project can pass the acceptance.
