Performance testing is a critical component of safe and reliable deployment of energy storage systems on the electric power grid. Specific performance tests can be applied to individual battery cells or to integrated energy storage systems.
The goal of the stored energy test is to calculate how much energy can be supplied discharging, how much energy must be supplied recharging, and how efficient this cycle is. The test procedure applied to the DUT is as follows: Specify charge power Pcha and discharge power Pdis Preconditioning (only performed before testing starts):
Performance, in this context, can be defined as how well a BESS supplies a specific service. The various applications for energy storage systems (ESSs) on the grid are discussed in Chapter 23: Applications and Grid Services. A useful analogy of technical performance is miles per gallon (mpg) in internal combustion engine vehicles.
A pilot plant using water as thermal energy storage working medium was constructed to investigate the performance of the CAES system with TES. An average round trip energy efficiency of 22.6% was achieved. Detailed analysis for a particular test was performed to study the major factors affecting the system.
Capacity testing is performed to understand how much charge / energy a battery can store and how efficient it is. In energy storage applications, it is often just as important how much energy a battery can absorb, hence we measure both charge and discharge capacities.
