Especially in the operation of long-haul trucks, fuel costs have a huge impact on the Total Cost of Ownership (TCO), which is the key entrepreneurial figure in the transportation business. Combined with route information, a Predictive Cruise Control (PPC) System increases the fuel-saving effects. In a MATLAB/Simulink model-based generic approach, the operating strategy and the PPC are optimized using a Genetic Algorithm (GA). The contradiction between minimizing the fuel consumption and simultaneously maximizing the vehicle speed in order to decrease time-related fixed costs has to be solved. This leads to a Multi-Objective Problem (MOP). The operating strategy is developed for a parallel hybrid topology that includes the fuel-saving functions of recuperating, boosting, shifting the load point (SLP) and electric drive only. The following methodology helps to answer the search for an optimum control parameter setup combining the operational strategy and the PPC System in long-haul operations. This paper describes the model building, simulation and optimization of a rule-based control strategy. The route profile and fuel consumption of an Internal Combustion Engine (ICE) truck were measured in a real-life test run. The recorded data are used for model building and to validate the simulation tool. With an optimized parameter setup, fuel-saving effects of up to 11 % with simultaneously increasing the vehicle speed were accomplished","PeriodicalId":395329,"journal":{"name":"2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"s1-8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127199305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is crucial as Lithium-Ion battery cells result in reduced lifespans if exposed to temperatures above 50°C. On the other hand, temperatures below 10°C lead to a reduced capacity and with respect to electric vehicles in reduced driving ranges. The OPTEMUS project therefore develops a thermal insulating battery module housing that thermally disconnects the battery cells from the ambient temperature, providing a more stable temperature profile and more efficient thermal management of the battery. Different housing materials and designs have been developed to provide thermal insulating properties while also withstanding mechanical forces. Based on a concept module design of Fraunhofer LBF, two different fiber reinforced plastic sandwich structures have been manufactured with insulating foam cores and analyzed with respect to their cellular structures and resulting thermal properties. The cellular structure was detected three-dimensionally via computer tomography analysis. The manufactured sub-module housings were tested in a climatic chamber at −10°C and compared to a benchmark housing design based on aluminum as construction material. Results showed that the cell temperatures decrease 250 to 400 % slower using foam core sandwich structures as housing material compared to an aluminum housing while providing large scale manufacturability via the injection molding process.","PeriodicalId":395329,"journal":{"name":"2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129799387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
