2 The Role of Energy Storage Testing Across Storage Market Development (Best Practices for Establishing a Testing Laboratory) This section of the report discusses the architecture of testing/protocols/facilities that are needed to support energy storage from lab (readiness assessment of pre-market systems) to grid.
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.
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.
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):
