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


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.
