European Competitiveness in Commercial Hybrid and Automotive Powertrains (ECOCHAMPS): Integration and Validation of Modular Standardised Framework Hybrid Components in a Heavy Duty Vehicle Driveline

Abstract

The ECOCHAMPS project has addressed the topic GV-04-2014 Hybrid Light and Heavy Duty Vehicles of the Green Vehicles work programme under Horizon 2020. This project realized, in a single, coordinated action, all the aspects of this call through the activities of a twenty-six member consortium representing the European Automotive Industry. At the time of the TRA in Vienna, the ECOCHAMPS project will just have been completed after three years of activity.
This paper will focus on the integrated components developed in the ECOCHAMPS project in a TRL 7 heavy duty vehicle as part of Work Package 7 lead by DAF, proving a significant CO2 reduction with a cost-effective driveline. For this purpose, an integral modular approach has been used to combine waste heat recovery and the hybrid system. The aim has been to achieve an increased combined fuel consumption reduction by utilizing synergy advantages. These advantages occur when the systems are connected through a common high voltage bus combined with an energy storage device, in this case a 400V DC bus and a hybrid battery. It is targeted to achieve a cost-effective powertrain efficiency improvement of 20% by using standardized, modular hybrid components.
