Description

Following the shift towards electrification, research into drive cycles, fast charging and aging of batteries is paramount. That's why we perform extensive research on batteries for all kinds of applications, including electric vehicles. In our battery labs, we test cells, modules and packs to help select the right battery cell for any application. Our testing infrastructure allows to perform endurance and ageing tests on battery packs. Our research infrastructure includes climate chambers to determine operational temperature ranges or to perform accelerated life tests.

We can run the following battery test:

  • Cycling and aging
  • Internal resistance through HPPC
  • High current pulse testing
  • Drive cycle testing
  • Fast charging testing
  • Post-mortem analysis
  • Heat distribution measurement
  • Electrochemical impedance spectroscopy

Furthermore we are able to fabricate test cells for proof-of-concepts and battery assembly optimisation

Below you can find all available battery testing infrastructure.
