      Introduction to American UL1973 Safety Standard Time:2021-12-20 13:26:33    Browse quantity:176   

      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 mainly covers various battery systems used for stationary, vehicle auxiliary power supplies, LER, photovoltaics, wind energy, backup power supplies, and communication base stations, and includes structural evaluation and test evaluation of energy storage systems, but this standard is only a safety standard. Does not include performance and reliability assessments.


      The scope of UL1973 standard covers the following application batteries

      1. Energy storage: photovoltaic power stations, wind power stations, UPS, household energy storage, etc.

      2. Vehicle auxiliary battery (not including power drive battery)

      3. Batteries for light-duty electric rails or fixed electric rail electric energy storage systems, not limited to chemical substances batteries

      4. Contains various types of batteries, with unlimited chemical substances, including beta sodium batteries and fluid batteries

      5. Electrochemistry

      6. Hybrid battery and electrochemical capacitor system
