Abstract

In the pursuit of higher energy efficiency, reduced usage of fossil fuels and lower emissions a refrigerated vehicle"br" based on hybrid electric technology for the delivery of goods in urban areas was developed. The electrically"br" operated cooling system is powered by the traction battery of the hybrid electric vehicle. Independent of the"br" vehicle’s operating mode the energy generation for the cooling system always works at highest efficiency of the"br" internal combustion engine due to the operating strategy of the hybrid system. This contribution describes the two"br" main tasks to successfully realize the hybrid-electric refrigerated vehicle: the development of a simulation model"br" and the buildup of a concept vehicle. The design and optimization was conducted by a multiphysical simulation"br" of the entire vehicle including all relevant vehicle- and cooling components. The function of the hybrid electric"br" refrigerated vehicle and the operational strategy were validated by several tests and also during a demonstration"br" phase by a company.
