Mercedes-Benz releases internal crash test results of EQC electric SUV

Mercedes-Benz is preparing to launch its first next-generation electric vehicle, the EQC electric SUV, and it is already releasing some internal crash test results.

Because it is the company’s first all-electric vehicle built to be electric from the ground up, the automaker said that it “applied stringent safety standards to the battery and all component parts carrying electrical current.”

It validated those standards at the Mercedes-Benz technology centre for vehicle safety (TFS), which the company claims is “the most advanced crash test centre in the world.”

Based on these crash tests, Mercedes-Benz said it was able to refine several safety features:

  • A new subframe surrounds the drive components located in the front section, and this unit is supported by the usual mounting points.
  • 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.
  • A battery guard in the front area of the battery is able to prevent the energy storage unit from being pierced by foreign objects.
  • 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.
  • In addition to assessing the occupant values during a crash, the battery’s accident safety was also tested at the development centre of Deutsche ACCUMOTIVE, a wholly-owned Daimler subsidiary. Test criteria included the battery’s behaviour under impact and when penetrated by foreign bodies, with overheating and overloading also simulated.

The company also tested and implemented other safety features unrelated to the vehicle’s battery pack:

  • Three-point seat belts with pyrotechnical belt tensioners and belt force limiters are installed for the driver, front passenger and passengers on the outer rear seats (normal three-point seat belt in the centre at the rear).
  • i-Size (Europe) and ISOFIX (other countries) child seat attachment points for securely attaching appropriate child seats on the outer rear seats
  • Window airbags in the roof area between the A, B and C-pillars for the head area of the driver, front passenger and passengers on the outer rear seats
  • Combined thorax/pelvis side impact airbags for driver and front passenger. Additional optional side impact airbags for the outer rear seats.
  • Airbags for driver and front passenger in the event of a severe frontal impact, with dual-stage, time-delayed deployment on the passenger side
  • Knee airbag for the driver
  • 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
  • Activation of the hazard warning system to warn other road users
  • Interior lighting switched on
  • Front side windows lowered for ventilation in the event of airbag deployment
  • Central locking system unlocked
  • Lifting of the electrically adjustable steering column
  • Notification of a detected breakdown or accident situation to Car-to-X communication and to the Mercedes-Benz service centre
  • A rescue sticker provides a direct link to the vehicle’s rescue data sheet. Corresponding stickers are affixed to the charging flap and to the opposite B-pillar of the vehicle for this purpose. In the aftermath of an accident, rescue services can scan the QR code with a smartphone or tablet PC for fast and reliable access to the rescue data sheet for the specific vehicle concerned, thus facilitating rescue operations.
  • Alongside the rescue data sheets, the Rescue Assist App for smartphones and tablets also has three-dimensional views of the vehicle – now also offline in case there is no mobile network available at the accident scene.

Mercedes-Benz claims that the EQC achieved a “high level of crash safety” based on these internal tests.

Electrek’s Take

These seem to be good safety features and I’m glad that Mercedes-Benz says that their own internal crash test results are encouraging. But as usual, we should wait for third-party crash test results in order to declare that the EQC has a “high level of crash safety.”

We shouldn’t have to wait too long.

Mercedes-Benz unveiled the production version of the EQC electric SUV in September and said that the production will start in 2019.

We are expecting more precise timing details in the coming months.
