Steel Requirements for Electric Vehicles
Peter Jones, Product Engineering Group Leader, Research & Development, Tata Steel will tell us about steel requirements for electric vehicles and the challenges faced as a consequence of vehicle manufacturers drive to meet government targets.
Vehicles powered by petrol engines have been around for the last 130 years and diesels for approx. 85 years, but that is now changing. The world is slowly running out of oil and the ever increasing environmental and legislative pressures mean the number of hybrid and full electric powered vehicles will steadily grow.
Current battery technology for electric vehicles mean the number and weight of the storage cells will drive different BIW designs and material requirements.
The 2 images show one of the preferred position of the battery pack and it’s interference with the traditional load paths through the BIW. One way of overcoming the problem of not being able to have load carrying structure go through the floor area is to go around it and dissipate the energy earlier in the crash event. To do this an ideal solution is to employ a secondary load path below the main side rail and then pass the load through a cross member into the sill area. Body designs and automotive structural engineers need to develop alternative designs solutions
