Experimental measurement uncertainty for test chambers for AC systems
Dr Gursaran Mathur Senior manager CalsonicKansei North America USA
Selecting proper instrumentation for test chambers is critical in achieving accurate results. This is a very important factor that needs to be assessed, reviewed and then specified to the manufacturer of the thermal chamber. Selection of proper instrumentation will result in thermal performance data with a very tight tolerance of measurement uncertainty. However, due to budget constraints, we often compromise the quality of the data by specifying cheaper instrumentation. The presentation will discuss a couple of scenarios that result in a significant difference in the experimental measurement uncertainty with different levels of instrumentation for thermal systems.
Holistic approach to testing lithium chemistry batteries at vehicle scale
Serge Gregory Senior associate Exponent Failure Analysis Associates USA
The increasing technological sophistication of automotive systems poses testing challenges that extend far beyond traditional evaluation techniques. A complex interplay of sensors, power and communication systems affects traditional automotive components, and these systems often do not have established test processes. Subcomponents that have industrial test specifications may be used outside of the tested performance envelope in automotive systems. For example, although a range of protocols exist for lithium chemistry batteries, the infrastructure to conduct such tests on vehicle-scale systems is lacking. Exponent has undertaken a holistic approach to vehicle testing, and is implementing system- and component-level test processes to meet these evolving challenges.
