Solutions for vehicles of the future: Our innovations at the IAA

Crash safety and body weight are important aspects in vehicle development and are also at the forefront of KIRCHHOFF Automotive's trade fair presence. Soon you will be able to see our innovations at our booth no. B16 in hall 9.

Here you already get an exclusive insight into our innovative products. At the IAA Cars 2019, our experts will be on hand to answer any questions you may have.

Battery Housing for E-Mobility

Based on our many years of experience in the development of crash-proof structures, we developed and presented an innovative battery housing for e-mobility two years ago.

This year, too, we show how our technology carriers can harmonize high process reliability, lightweight construction and cost-effectiveness. These are the development focal points:

  • Economical aluminum and aluminum-steel hybrid solutions
  • Integrated crash safety and underbody protection
  • Scalability for application in various vehicle versions and derivates
  • Tightness concept: built tank / folded tank
  • Joining technologies and leak tightness requirements: Thermal joining processes, mechanic joining processes, glueing
  • Narrow flatness tolerances
  • Battery housing made of aluminum (closed)

  • Built battery housing with a floor plate

  • Battery housing with folded tub

  • Alternatively with steel cover e.g. for higher fire protection requirements

  • Hybrid battery housing with folded tub

Rear Bumper with Challenging Profile

In a joint project with thyssenkrupp Steel Europe, we developed a hot-formed rear bumper characterized by the use of new hot-forming grades.

The hot forming process achieves greater component stability and material strength, enabling the rear bumper to better protect vehicle occupants in the case of a crash. The use of press-hardened steel allows economical lightweight steel construction.

The crash management system is characterised by the following features:

  • The profile with changing opening direction is an advantage for the performance of the CMS.
  • No striking plate required, reduces weight and material and joining process costs

Economical Lightweight Construction: Weight-Optimized B-Pillar

Crash Management System according to latest Euro NCAP guidelines

With the Crash Management System, KIRCHHOFF Automotive has further developed one of its core products in order to meet the requirements of passive safety according to the Euro NCAP guidelines with the new MPDB test. In the event of a crash, the energy input is distributed and absorbed over a large area. In this way, all those involved in a crash are to be protected.

If a large, heavy vehicle collides with a small, light vehicle, the risks for the occupants of the latter are often many times higher. The reason for this lies in the structures that are often not tuned to each other, so that the smaller vehicle usually absorbs a larger proportion of the energy. The CMS, specially developed for the MPDB test, acts like a protective shield and focuses not only on the safety of the person responsible for the accident but also on the safety of the other party involved in the accident. The Euro NCAP guideline will apply from 2020. KIRCHHOFF Automotive is therefore already a pioneer in this field.
