Chinese heavyweight EVE Energy has announced that the world's first utility-scale battery storage project featuring 628Ah ultra-large cells has entered operation in China.
world’s first 100 MWh-class battery energy storage facility using 628 Ah ultra-large battery cells has entered operation.
No, you’re still missing voltage to give you the total energy storage, or Watt-hour (wh). For a cell of known chemistry, the voltage is implied. For example, lithium ion’s nominal voltage is ~3.7V. However, the term “battery” is ambiguous. Could be one cell, could be many strapped together to form your “battery”. See 12V lead acid batteries. Therefore, Ah is only half the answer.
But isn’t AHr a better measure for battery storage ?
