Ideal EVs of the future will have no engine, no chemical batteries and will derive the required energy from conventional power grid or from non-conventional generating stations ranging from solar, nuclear, microhydel, wind generators, biomass/biogas plants or wave generators. The problem at that time will be an economically viable storage medium. Such a medium is on the horizon for some time. Typical contestants are flywheel, Li-ion, ultra caps and Zn-air. The present technology available does not support economic use of the above storage mediums. However in special circumstances such as remote or hilly area transportation or defence, Li-ion and flywheel can be considered.","PeriodicalId":129674,"journal":{"name":"2006 IEEE Conference on Electric and Hybrid Vehicles","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117338182","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}

However, the electric vehicle suffers from relatively short range and long charging times and consequently has not become an acceptable solution to the automotive consumer. The addition of an internal combustion engine to extend the range of the electric vehicle is one method of exploiting the high efficiency and lack of emissions of the electric vehicle while retaining the range and convenient refueling times of a conventional gasoline powered vehicle. The term that describes this type of vehicle is a hybrid electric vehicle. Many configurations of hybrid electric vehicles have been designed and implemented, namely the series, parallel and power-split configurations. This paper describes parallel hybrid electric vehicles that are battery dominant and have the ability to externally recharge from the wall socket. Both component selection and control strategy is discussed. Additionally, a definition of the degree of hybridization, or a description of the relative size of the electric motor to the internal combustion engine is presented. Finally the discussion will illustrate that an increasing degree of hybridization leads to higher overall vehicle efficiency, namely fuel and energy economy.","PeriodicalId":129674,"journal":{"name":"2006 IEEE Conference on Electric and Hybrid Vehicles","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129448330","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}

An efficient transmission system always leads to better fuel economy. As we know, parallel hybrid vehicles use electric as well as fuel power simultaneously to drive the vehicle. For specific power developed, since (Power) = (Torque)middot(Speed), for a specific speed, optimum torque will be well defined. If we use conventional gearbox in the transmission train, we get stepped speeds. It is not possible to tap any intermediate speed from conventional drive. Concept of 'Proportional Loss of Speed' says that if we want a specific speed, which is not available in the conventional gear train for a particular instant, the higher or lower speed chosen, causes loss of power. Since electrical as well as mechanical efficiencies are both defining the total efficiency of the drive, it is not desirable to allow loss of power at any instant. That means we must use such a drive in which any particular speed in the given range can be tapped. This is possible using continuously variable transmission (CVT). This paper will discuss mechanical transmission system design and CVT control philosophy to optimize energy efficiency of the system.","PeriodicalId":129674,"journal":{"name":"2006 IEEE Conference on Electric and Hybrid Vehicles","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115887930","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}

So a number of methods to increase the performance of the internal combustion automobile engines have been established. A better method of utilizing the exhaust is being achieved by this paper. The method uses the exhaust gases from an optimal sized engine currently used. This pressure and temperature is being used and sent through a nozzle or set of nozzles which reduces the pressure to about 1.3 bars and generates high velocity gases at exit. This high velocity gas is being utilized to drive a turbo generator (turbine coupled with a generator) which powers the auxiliary units such as the car batteries head lights etc. so fuel economy is greatly saved which is the need of the hour. This paper thus incorporates the use of axial flow impulse turbine which is better than radial flow proven by current researches. The power obtained is better than conventional systems using the exhaust gases. The aim thus ascertains that power is given to all auxiliary systems such as the air conditioners, head lights, can be used to charge the batteries of the car implying that fuel economy is increased.","PeriodicalId":129674,"journal":{"name":"2006 IEEE Conference on Electric and Hybrid Vehicles","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123396818","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 fuel cell (FC) will be as big a technological marvel as the internal combustion (IC) engine has been a century ago as compared to the heavy old external combustion steam engines. Automotive companies also know that fossil fuels are nearing to an end and that FC power train will be the propulsion system for future vehicles. REVA Electric Car Company (RECC) has developed the world's smallest fuel cell powered prototype vehicle. The electric car that is powered by a set of EV tubular lead acid batteries now has fuel cell energy constantly charging the batteries. Its 70 N-m high torque motor gives it quick acceleration and speed. The fuel cell system is powered by high-pressure hydrogen. The main components: fuel cell, high-pressure hydrogen tank etc. are modularized by integrating and completely placing over rear seats. This paper presents the development of prototype phosphoric acid fuel cell pick-up electric vehicle by RECC along with Naval Materials Research Lab (NMRL), Ambernath, District Thane, Maharashtra State, India. The phosphoric acid fuel cell (PAFC) mounted at the rear of the vehicle obviates the need of carrying a hydrogen cylinder on board.

Over a period of time, due to rising fuel costs, shortage of fuel and also due to the pressing need to reduce the air pollution, electric hybrid vehicles appear to be a clean and green alternative to IC engines. In this paper, various battery technologies such as lead-acid batteries, nickel metal hydride (Ni-MH) batteries, zinc-air fuel cells are evaluated in terms of technical and commercial viability for an electric vehicle application.
