The second edition of UL1973 was released on February 7, 2018. It is a safety standard for energy storage battery systems in North America and a dual-country standard for the United States and Canada. The standard covers various battery systems used for stationary, vehicle auxiliary power supplies, LER, photovoltaics, wind energy, backup power supplies, and communication base stations. It includes structural and tests evaluation of energy storage systems, but it is only a safety standard. Does not include performance and reliability assessments.
The UL1973 standard covers batteries for the following applications:
• Energy storage: photovoltaic power stations, wind power stations, UPS, household energy storage, etc.
• Vehicle auxiliary battery (not including power drive battery)
• Batteries for light rail or fixed rail power storage system
Unrestricted chemical substance battery
• Contains various types of batteries, with unlimited chemical substances, including beta sodium batteries and fluid batteries
• Electrochemistry
• Hybrid battery and electrochemical capacitor system
