Introduction

1. Background of Standard Revision and Technical Evolution

GB/T 36558-2023 "General Technical Conditions for Electrochemical Energy Storage Systems in Power Systems" is revised on the basis of the original standard GB/T 36558-2018, mainly optimizing the technical requirements and scope of application. The new standard adds detailed provisions on storage environment conditions, and supplements technical details on operational adaptability, energy conversion efficiency, etc.

2. Comparison of standard frameworks

Standard version	Scope of application	New content	Revised content
GB/T 36558-2018	Lithium-ion batteries, flow batteries and other energy storage systems	-	- Delete some term definitions, adjust power control requirements
GB/T 36558-2023	Expanded to sodium-ion batteries, water electrolysis hydrogen production and other technical routes	Added storage environment conditions requirements	Supplemented operational adaptability and system frequency regulation capability regulations

3. Interpretation of the core content of the standard

3.1 Environmental conditions

The operating environment temperature range of the electrochemical energy storage system is -20°C to 50°C, and the storage environment is required to be between -30°C to 50°C. For marine climate applications, corrosion resistance needs to be specially considered.

3.2 System technical requirements

• Power control response time: The active power control deviation shall not exceed ±1% of the rated power, and the reactive power deviation shall not exceed ±3%.
• Energy conversion efficiency: The efficiency of lithium-ion battery energy storage system shall not be less than 83%, and the efficiency of flow battery shall not be less than 65%.

4. Implementation suggestions

4.1 Equipment selection considerations

Choose the appropriate energy storage technology route according to the actual application scenario. For example, < b class="instrument">lithium-ion batteries can be used preferentially on the user side, and < b class="instrument">flow batteries are recommended for grid-side projects.

4.2 Operation and maintenance suggestions

• Regularly check whether the environmental conditions of the energy storage system meet the standard requirements.
• Strengthen the operating status monitoring of the battery management system and < b class="instrument">energy storage converter to ensure the normal protection function.
