Introduction
The country has put forward the climate action goals of carbon peaking and carbon neutrality, and it is necessary to build a clean, low-carbon, safe and efficient energy system and control fossil energy:
The total amount of renewable energy is implemented, and a new power system with new energy such as solar energy and wind energy as the main body is constructed: But wind and solar
With the unstable and discontinuous characteristics of power generation, the configuration of energy storage can fundamentally solve this problem and achieve safe and stable power supply: in the near future
In the future, the application of energy storage in various links and scenarios is bound to increase significantly, and the standard for energy storage batteries should be the first: GB/T 22473 "Storage for energy storage
Battery" specifies the technical requirements and test methods for storage batteries for photovoltaic power generation equipment, and guides the manufacture of storage batteries more scientifically:
Enterprise technology upgrade, guide users to carry out technology selection, operation and maintenance, etc: The main problems it solves are:
--- specifies the terms, definitions, symbols and abbreviations for storage batteries used in photovoltaic power generation equipment;
---Specifies the model compilation method of batteries for energy storage of photovoltaic power generation equipment;
---Specifies the technical requirements, test conditions and test methods for storage batteries used in photovoltaic power generation equipment;
--- specifies the inspection rules for storage batteries used in photovoltaic power generation equipment;
---Specifies the marking, packaging, transportation and storage of storage batteries for photovoltaic power generation equipment:
