Vehicle Scale Thermal Chamber

In response to the needs of its automotive clients, Exponent created and now maintains a custom thermal test chamber to allow environmental testing of vehicle-sized devices over the temperature range -20°F to 130°F. The test chamber is controlled with custom software written in NI LabVIEW, and is able to hold temperature over the relevant operating range to within approximately 1°F. While originally built for automotive testing, the chamber can accommodate any device within the usable volume of approximately 14’ W x 19’ H x 37’ L.

The system has been used to help understand the short- and long-term effects of hot and cold exposure on vehicle electronic systems, as well as the temperature-modulated performance of vehicle- and home-scaled battery cells. The chamber pairs with a number of flexible data acquisition systems at the Test and Engineering Center allowing for simultaneous capture of multi-channel data from sensors and/or electronic components in or on the device under test.
