Here vehicles, including prototypes with large electric batteries, have been tested under harsh crash conditions.
The result is a whole array of constructive measures which deliver the EQC's high level of crash safety:
- The battery is surrounded by a robust frame with an integral crash structure. Deformation elements are installed between the frame and the battery, and these are able to absorb additional forces in the event of a severe side impact.
- The high-voltage system can also be shut down automatically in a crash, depending on its severity. A distinction is made between a reversible and an irreversible cut-off. When it is shut down the voltage in the high-voltage system outside of the battery reduces to below the safety-relevant voltage limit in a very short time.
- Another feature of the comprehensive high-voltage safety concept is that the charging process is automatically curtailed if an impact is detected when stationary at a quick-charging station (DC charging). There are also shutdown points where emergency teams can deactivate the high-voltage system manually.
- Automatic activation of Mercedes-Benz emergency call to notify emergency services of the location and emergency situation and initiate rescue.
- Shutdown of the high-voltage system
- Lifting of the electrically adjustable steering column
