There is a growing demand for low carbon vehicles to reduce the transport sector's environmental impact and respond to the pressure of decarbonisation. Over the last 5 years, battery costs and performance have improved significantly which has subsequently improved the viability of electric and hybrid vehicles. By taking a whole-systems approach to electrification for efficiency, this collaborative research programme will focus on gaining underpinning knowledge on battery performance and degradation, new devices and packaging for power electronic, design of electric motors that include manufacturing effects and addressing the challenges that electric drives for torque transmission impose on surfaces, substrates and lubricants to optimise materials for drives. This research will address the fundamental research challenges to accelerate electrification of vehicles in the UK. It will deliver new scientific insights to drive forward discovery and innovation in electric and hybrid vehicles. The knowledge generated by this research programme will provide a route to maintain and grow jobs as low emission vehicles replace existing vehicles and will have impacts across the supply chain.
