The CO2 limitation decided by the European Commission challenges the Automotive OEM’s to further improve the conventional powertrain with regard to CO2 Emission reduction. Thermal Engine concepts alone need to be supported by alternative propul-sion solutions in order to meet the fleet average CO2 limits in order to get benefits from the utilization of the transient driving conditions in term of electrical boost and break recuperation. Most of the current hybrid vehicles in the market match these requirements technically. From a commercial point of view there is the need to further attractiveness – means price improvements. Besides the value add for the Battery the additional cost of hybrids are mainly influenced by the implementation of HighVoltage systems that need extensive technologies for electrical safety requirements. The new 48 Volt Voltage level could be a solid solution to improve CO2 emissions aligned with cost optimization within hybridization. Technically the application of various different voltage levels within a vehicle needs investigation from an electrical systems and component point of view. The presentation explains the technical challenges and offers an overview on possible solutions and gives a comprehensive insight to hybridization.
