Electrochemical energy storage represents a new form of business in the energy storage industry. To support the development of new energy, the construction of electrochemical energy storage power stations has been developing at an increasingly rapid rate in the past years. An update on standards and specifications on electrochemical energy storage therefore is urgently needed to keep up with market demands.
On 21 June, China’s Ministry of Housing and Urban-Rural Development released a draft for the national standard, Design Code for Electrochemical Energy Storage Station, and called for public opinions on it.
The standard consists of 14 chapters: general provisions; terms; basic requirements; site selection; general plan and layout; grid connection, electrochemical energy storage system; electric, architecture and structure; heating, ventilation and air conditioning; water supply and drainage; fire protection and safety; environmental protection with soil and water conservation; labor and occupational safety. This standard is applicable to the design of new, reconstructed, and expanded stationary electrochemical energy storage stations with power exceeding 500kW and capacity exceeding 500kW·h.
The revision of this standard focuses on adjusting its original chapters concerning firefighting. Specifically, it moves fire protection requirements to the firefighting chapters and adds requirements on smoke prevention, discharging, power supply, and emergency lighting. It also revises the fire protection design requirements for lithium ion batteries, lead acid (lead carbon) batteries, and liquid flow batteries.
In short, this standard will contribute to standardizing the design and improving the construction quality of electrochemical energy storage stations, thus effectively ensuring their operation and maintenance safety.
