Concept study of a hybrid-electric refrigerated vehicle with electrically operated cooling system for urban freight transport

Abstract

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