So, hybridization of both conventional ICE and electric motor powertrain systems hold great promise for environmentally friendly vehicles (EFV) to meet stringent CO2 regulation and fuel economy requirements. This paper presents the effects of the initial state of charge (SOC) stored in the vehicle’s battery on tractive propulsion characteristics as vehicle drivability performance that is obtained from both ICE and an electric motor simultaneously. Especially, the battery management system (BMS) plays a key role in a hybridized system based on an electric device. And a regenerative braking system recovers kinetic energy from braking and uses it to recharge the battery. In this study, in order to investigate the effects of various initial SOCs in a parallel hybrid gasoline-electric vehicle (HEV), an experiment was carried out on a vehicle chassis dynamometer with IM240 vehicle driving mode and a CAN protocol analyzer to collect data from a full HEV. A unique hybrid electric signal processor was designed to monitor the operational state of the ICE including fuel injection duration, hybrid starter-generator (HSG) and propulsion motor which depend on the initial SOC. The amount of energy recovered through the regenerative braking system was measured to investigate the collect rates of currents. The results show that the initial SOC stored in the battery causes big differences in the electric current balance in hybrid operating mode, and that careful coordination of ICE and motor is necessary to achieve vehicle propulsion capacity as well as to maintain the battery SOC at a reasonable level.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"169 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74222684","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}

Under a wide range of working conditions (Varying Condensing temperature, Evaporating temperature, Sub cooling and sub heating with Internal heat exchanger (IHX) and without internal heat exchanger) on simple vapor compression system, we compare the energy performance of both refrigerants - R134a and HFO1234yf. Result shows that without using an Internal heat exchanger, At lower condensing temperature (35oC), Mass flow rate increases about 27-32%, refrigerating effect decreases 22-25%, co mpressor work increases 4-6% and COP decreases about 3-5%. While at higher condensing temperature (55oC), mass flow rate increases about 35-42%, refrigerating capacity decreases 27-30%, and compressor work increases 8-13% and COP decreases 7-10%. Using an internal heat exchanger (IHX), these differences in the energy performance are significantly reduced. At lower condensing temperature (35oC), mass flow rate decreases about 18-22%, refrigerating capacity decreases 15-18%, compressor work increases 1-3% and COP decreases about 2-3% and At higher condensing temperature (55oC), mass flow rate decreases 23-28%, refrigerating capacity decreases 18-22%, compressor work increases 5-8% and COP decreases about 4-7%. The energy performance parameters of HFO1234yf are close to those obtained with HFC-134a at Low condensing temperature and making use of an IHX. Even though the values of performance parameters for HFO1234yf are smaller than that of HFC-134a, but difference is small so it can be a good alternative to HFC-134a because of its environmental friendly properties with introducing IHX.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"40 1","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80316226","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}

The master controller provides this centralized unit. It interacts with all other networked control electronics to control the dynamic driving demands. In a hybrid vehicle, the master controller not only provides a communication interface, but also an efficient energy management, coordination and performance during the various vehicle-specific drive cycles. The control complexity at the master control unit is greater in the hybrid car because of the extra energy resources integrated into the vehicle. This work presents the design, implementation and testing of the Kiira EV SMACK vehicle master control unit. In the Kiira EV SMACK, the master controller oversees the human machine interfaces, low voltage electronics, the motor and generator controllers, battery management and thermal management systems. A model based design approach was followed to implement the controller logic for initiation of startup of the low level controllers and implementation of a power source switching strategy. The switching strategy is based on speed demands and available energy resources (battery state of charge and fuel capacity).","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"21 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2015-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90502838","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}
