Objectives:

To assess the safety performance of high voltage batteries in severe crashes.

Methodology:

Comprehensive series of dynamical impact tests with all types and sizes of high voltage batteries used in the current Mercedes-Benz hybrid and electric vehicles.

Key Findings:

  • Despite the high loads and the resulting major battery intrusions, no thermal or electric reactions occurred, neither short circuits, nor electrolyte leakages, nor fire or explosion.

  • A very high crash safety performance was demonstrated for all the batteries.

Keywords:

Crash, high voltage battery.
