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.
Integrated system tests are applied uniformly across energy storage technologies to yield performance data. Duty-cycle testing can produce data on application-specific performance of energy storage systems. This chapter reviewed a range of duty-cycle tests intended to measure performance of energy storage supplying grid services.
Let's collect some information so we can connect you with the right person. UL can test your large energy storage systems (ESS) based on UL 9540 and provide ESS certification to help identify the safety and performance of your system.
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):
As more battery energy storage systems (BESS) are connected to the grid, safety is paramount. That’s why clear safety standards exist for the storage industry; protocols including UL 9540, UL 9540A, and NFPA 855 aim to quantify how well batteries stand up to worst-case situations.
Integrated energy storage systems can include batteries, or non-battery technologies such as flywheels, capacitors, or compressed air. Integrated system tests are applied uniformly across energy storage technologies to yield performance data. Duty-cycle testing can produce data on application-specific performance of energy storage systems.
