Modular Chassis Data Logger for Laboratory and On-road Experimental Tests of Battery Electric Vehicles

Energy consumption and efficiency of Battery Electric Vehicles (BEVs) are key topics to determine the usability and potential of electric vehicles in real-world, and the correct identification of the real-driving conditions is a key aspect to define effective type approval regulation for future vehicles. In this respect several aspects must be addressed, such as the representativeness of different test duty cycles versus real driving, the impact of different environmental conditions as well as the energy demand of auxiliaries in different operation conditions. In the last years the Joint Research Centre of the European Commission has initiated pre-normative research on hybrid and battery electric vehicles, in order to support policy makers with independent expertise to define better and more representative EU type approval test procedures for electrified vehicles, and harmonise the current reference EU regulation at global level in the framework of the activities of the UNECE. Among the several technical issues tackled, one aspect has involved the design of a test program and the set-up of a customisable, portable and lightweight on-board data logger capable to provide real-time synchronised measurements on the vehicle of all the relevant parameters, in order to accurately determine the fuel and energy consumption and the overall energy efficiency performance for both hybrid and battery electric vehicles. The purpose of this paper is to present this instrument (i.e. PeMS, Portable energy Measurement System), its modular structure, its potential and its application in a comprehensive test campaign carried out in 2014 on a reference battery electric vehicle. Acquired data from the PeMS are compared with vehicle CANbus data, to assess the accuracy and potential of the instrument.
