Wholistic simulation of an all-electric refrigerated delivery vehicle

Large amounts of goods have to be discarded because of a disrupted cooling chain, where last mile delivery is often the crucial part. For future refrigerated trucks which are fully electrified the limited battery capacity calls for detailed investigations. The main contribution of this paper is a detailed model of such an electric truck together with an electric cooling unit, which covers both the power consumption of the drive train and the cooling unit for various driving conditions. The proposed simulation framework is parameterized using measured data from literature, it comprises different weather conditions, door openings, traffic volume as well as the driver aggressiveness. The simulation model uses a minimum number of parameters for an easy fit, and due to it computational efficiency it can be used for applications like model predictive control.
