Durability measurement in e-mobility

April 27, 2022, 10:00 am (CET)

Duration of the presentation: approx. 30 minutes

Speaker: Timo Eich

Testing of durability poses great challenges for the measurement equipment to be used, especially in the high-voltage environment. For example, the so-called "swelling" is to be investigated on HV battery cells. For this purpose, strain gauges are primarily used whose output signals, some of which are very small, must be recorded precisely, reliably and safely at a high voltage potential.

  • Which critical points in the electric vehicle typically have to be examined for their durability?
  • How can the signals of bridge-based sensors such as strain gauges be acquired in a HV-safe manner?
  • What challenges arise in particular with strain gauge measurements at HV potential and how can they be solved?
