Key Infrastructure and Services

  • Space to accommodate up to two 20-foot shipping containers or large commercial vehicles up to the size of a city bus
  • Bi-directional DC power stations up to 660 kW to accommodate battery cycling and battery emulation.
  • Large drive-in environmental chamber infrastructure (mechanical system build-out based on project needs)
  • Full suite of AC and DC Research Electrical Distribution Bus (REDB) connections
  • Advanced hardware-in-the-loop and model-in-the-loop simulation capabilities, including real-time digital simulator (RTDS) and Opal-RT racks
  • Robust safety design to handle many types of battery or energy storage systems
  • Thermal buses, natural gas, compressed air

Types of Research

  • Performance assessments of batteries, power conversion equipment, capacitor systems, or DC systems such as commercial microgrids
  • Long-duration reliability and safety tests of battery or energy storage system components
  • Development of economic models for energy storage systems via hardware-in-the-loop tests driven by market signals and grid conditions requiring multiple services from energy storage
