Systems and Components for E-Mobility

Capacity Area A1 addresses the challenge of storing electrical energy as the main barrier for the introduction of electric propulsion and auxiliaries for automotive applications independently of the proposed system solution (Battery Electric, Fuel Cell and Hybrid Vehicles). To-day’s technical problems include different aspects such as performance, reliability, lifetime and price. The proposed Battery Technology Platform would provide basic and essential research capacities for the devel-opment of battery systems in the targeted market of Rail, Bus, Truck, Construction, Agricultural and Utility Vehicles. Research efforts of the Battery Technology Platform would range from basic technology research related to sizing and performance of different battery technologies to the development and testing of specific battery systems for small and medium enterprises. This would allow – in addition to rail - for a significant part of the Swiss Automotive and Freight Industry to enter the market of electrified propulsion. This in turn would enable the development of powertrains, auxiliaries and vehicles that meet energy and emissions regulations while the Swiss industry would maintain and/or expand a competitive advantage.

Systems and Components for E-Mobility - Efforts to increase the overall efficiency while reducing emissions will also affect manufacturers of niche markets (e.g. rail vehicles, busses, municipal vehicles, agricultural and construction vehicles), especially regarding the development of key components of drive trains with an emphasis on energy storage systems for hybridization and electrification. A recent US DOE study (Feb. 2013) found that there is room for technological and operational improvements in energy efficiency for the non-LDV (non-light duty vehicles) in the range of 15-30% up to 2030. Governments, political parties, international and national bodies as well as users themselves place increasing demands on the automotive and construction equipment industries to supply products with high fuel efficiency and very low CO2 emissions.
