The requirement for ever-lower emissions is accelerating the automotive industry’s electrification strategies. The product line-up on offer now ranges from HEVs (ICE combined with an electric powertrain) to so-called plug-in PHEVs (rechargeable hybrids) to purely electrically powered vehicles (BEVs). It is not just the number of variants that is increasing, but also the control and communication complexity of the powertrain. These are primarily the interaction between driver acceleration, braking, battery modules, electric motors, power electronics and transmissions. Information and communication technology will be smaller and smaller and how does this translate into our electric mobility? Single throttle driving is a first step towards more intuitive driving, however what happens if somebody gets stressed and presses the pedal to the floor! Sensors are required to reduce the speed of vehicles in case this happens. Further a crumple zone is still present since we do not trust technology. Trust and feeling are difficult to capture, hence our vehicles are still heavy and loaded with safety systems. The battery also needs intelligence and thermal protection, hence the computational power in a vehicles has risen exponentially. How to deal with this and the dependency on ‘microchips’, integrated circuits.
Supply chain and recycling will be key in the future!
