Energy storage harness test conditions

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 Recommended Practice for characterization of energy storage technologies?

Purpose: This recommended practice describes a format for the characterization of emerging or alternative energy storage technologies in terms of performance, service life, and safety attributes. This format provides a framework for developers to describe their products.

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.

Does industry need energy storage standards?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry professionals indicate a significant need for standards …” [1, p. 30].

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):

Do we need a standard test procedure for field performance and health monitoring?

To our knowledge, no standard test procedure currently exists specifically for field performance and health monitoring. Such a test procedure should be easily conducted in the field with a minimum of equipment and time but able to capture BESS-specific metrics. Round-trip efficiency and useable energy are exemplary performance and health metrics.
