Energy Storage
Thermal energy storage draws electricity from the grid when demand is low and uses it to heat water, which is stored in large tanks. When needed, the water can be released to supply heat or hot water. Ice storage systems do the opposite,

6 FAQs about [Energy storage test plan]
What is energy storage performance testing?
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.
What is a stored energy test?
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):
What is energy storage performance?
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.
What is the energy storage standard?
The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.
How can ul help with large energy storage systems?
We conduct custom research to help identify and address the unique performance and safety issues associated with large energy storage systems. Research offerings include: 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.
What does an energy storage expert do?
Our energy storage experts work with manufacturers, utilities, project developers, communities and regulators to identify, evaluate, test and certify systems that will integrate seamlessly with today’s grid, while planning for tomorrow.
