Environmental Chambers and Isothermal Baths

Our two environmental chambers and two isothermal baths maintain accurate temperature control during energy storage systems tests. For instance, the Partnership for a New Generation of Vehicles (PNGV) Battery Test Manual requires stringent control of batteries during testing, which can be accomplished with environmental chambers and isothermal baths. Furthermore, energy storage systems behave differently at different temperatures, so maintaining a known temperature helps model future energy storage systems.
