Increasing number of powertrains adds to manufacturing complexity

Increasing number of powertrains adds to manufacturing complexityA recently published ABB-sponsored report highlights the challenges faced by car manufacturers as the transition to electrified vehicles gathers pace, bringing with it the need to manage huge complexity in assembly and supply chains.

According to Flexing for the Future, a 2035 Global Powertrain Forecast Report — sponsored by ABB Robotics and authored by the automotive intelligence unit of Ultima Media — car manufacturers must adopt ‘a more flexible and collaborative approach to their production and logistics infrastructure’ if they are to maintain profitability and quality into the next decade.

Faced with ambitious targets for mitigating climate change together with huge regional variations in regulations and consumer attitudes, manufacturers are responding by developing platforms and production facilities that accommodate a complex mix of powertrains, from petrol and diesel to hybrid and battery-electric, as well as emerging technologies such as hydrogen fuel cells.

The report says this variability introduces a new level of complexity “that extends far beyond the factory walls and throughout the global logistics and supply chains. With conventional internal combustion (ICE) powertrains sharing little with their EV successors, the sheer variety of components and processes that must be supported can quickly become unmanageable.

“Added to which, the speed with which market conditions, Government incentives, legislation, and even the underlying technology itself can change means that manufacturers must seek to engineer even greater flexibility into their production facilities if they are to respond to this uncertainty.”

Joerg Reger, managing director of ABB Robotics’ automotive business, said: “By unravelling traditional long-line production architectures and deploying dedicated modular cells, manufacturers gain the ability to modify or even replace individual cells without incurring costly production interruptions.

“These ‘zero-loss’ production changes allow OEMs to start small and scale up key parts of the assembly process by adding or redeploying cells as demands change. By engineering flexibility into the process, we create the means to not just manage this rising complexity, but to turn it into an opportunity.”

The report suggests that one of the most significant technologies in supporting this flexibility is the switch to more autonomous logistics and material handling in plants, with OEMs increasingly relying on autonomous mobile robots (AMRs) to move materials flexibly.

“By creating a ‘digital twin’ of the facility, changes can be examined and optimised beforehand, and once a cell’s design has been perfected in the virtual space, it can be quickly rolled out as a fully validated unit anywhere in the world. Cellular manufacturing also allows robots to be redeployed or moved to areas of high demand with a ‘lift and shift’ process, meaning an asset can extend its life beyond its original purpose.”
