Battery Abuse Center

Introduction

A test bench is being developed at the Battery Abuse Center. This is to investigate the reactions of batteries to loads occurring in the vehicle.

Information

  • The Battery Abuse Center (BAC) test facility can test not only battery cells, but also battery modules and complete battery pack systems of electric vehicles, including their battery management system (BMS).
  • In the BAC, lithium-ion batteries can be examined for mechanical, electrical and thermal abuse events.
  • A standard specific certification (e.g. UN T 38.3) can be realized from cell level as well as from pack level.
  • The test bay is equipped with a 10 t crane (8 m high) for handling the lithium-ion battery.
  • Safety equipment of the BAC test chambers:
- High fire protection regulations (fire retardant classes FH90)

- Smoke/gas exhaust system
- Nitrogen and compressed air flushing
- Water mist for active cooling
- camera system
- Metal fire extinguishers (class D)
- Sensors for explosion gases (measurement of air composition)
- Design of the building according to EUCAR Hazard Level 7 (Explosion)

Research goals

  • Certification of lithium-ion batteries according to approval-relevant test standards.
  • Post mortem analyses to investigate the quality influences of various production parameters.
  • Checking the reactions of batteries to loads occurring in the vehicle, such as accidents or vibrations.
  • Electrical effusion on batteries, to define electrical load limits.
  • Fatigue tests and load tests according to manufacturer's specifications for all vehicle components.
