De-carbonising the electricity networks requires a move towards renewable energy generation and novel use of energy storage in electricity distribution. This will give a second income stream for e-vehicle batteries, reducing the impact of their cost. This, combined with the move to automated driving, also offers the possibility to develop mobility devices with additional functionalities at lower cost. One possibility is a radical new Electrical/Electronic-system (E/E-System) architecture, a possibility that stems from the reduced complexity of an electric power train. It is possible to create a modular, transferable structure that starts with drive-by-wire and extends to fully autonomous driving. This will also enable a vehicle to communicate with a new ICT-based infrastructure (with Car2Car and Car2Infrastructure communication) that will be required to deliver safety and reliability in future mobility. Mobility may become a service on demand, where vehicles are intelligent agents operating within the Internet of Things.
