The results achieved with the NiMH-UHP-technology not only support use of NiMH power assist batteries for future hybrid vehicles, but also open up additional fields of application for new 42V-vehicle electrical supply systems. Specific power which comes close to the 1000 W/kg level signifies an increasing degree of competition for capacitor systems since, in addition to comparable power levels, they also offer an energy storage capacity which is around 20 times higher. Use in electrical and hybrid vehicle prototypes demonstrates that the NiMH system can have a particularly interesting role to play in the future of vehicle construction. Its particular strengths are to be found in its high gravimetric and volumetric power data and its longevity in terms of energy throughput figures and calendar life. In the fields of development and production engineering, the lithium-ion high-power battery still lies several years behind the corresponding NiMH system for applications in the automotive sector. The results achieved to date nevertheless show that considerable potential exists in terms of power levels which it will be important to exploit in the future. Specific power levels up to 1500 W/kg with specific energy levels of up to 80 Wh/kg appear feasible. The main problem at the current time is the calendar service life, particularly under temperature conditions such as those that can be expected in automotive applications.
