Analysis of CO₂ reduction potentials and component load collectives of 48 V-hybrids under real-driving conditions
The development of innovative powertrain technologies is crucial for car manufacturers to comply with decreasing CO₂ emission limits. They face the challenge to develop products which fulfill customer requirements in terms of functionality, comfort and cost but also provide a significant CO₂ efficiency improvement. 48 V-hybrids can achieve these conflicting goals due to their low vehicle-integration effort and system costs while substantially increasing powertrain efficiency. The variance of real-driving scenarios has to be considered in system development to achieve the maximum customer benefit with the chosen system design, such as installed electrical power or topology. This paper presents a comprehensive investigation of different 48 V-system designs under real-driving conditions. The influence of varying real-driving scenarios on component load collectives is analyzed for P1 and P2 topologies. Furthermore, the CO₂ reduction potential and the influence of different hybrid functions such as electric driving is identified. The contribution of this paper is the identification of [Formula: see text]-system potentials under real-driving conditions and the corresponding component requirements, in order to support the development of customer-oriented 48 V-systems.
