Cycle Life: Cycle life refers to the number of charge-discharge cycles that a battery can undergo while still maintaining its specified performance and capacity. It is an important specification that determines the lifespan and longevity of the battery system.
Environmental Conditions: BESS specifications may also include information about the operating temperature range, humidity range, and other environmental conditions within which the system can operate effectively and safely.
After you get the specifications, then you do the battery energy storage system design. It’s important to note that these specifications can vary significantly depending on the specific battery chemistry, technology, application, and manufacturer. Therefore, it’s essential to consult the product documentation or manufacturer’s specifications for precise details about a particular battery energy storage system.
