The algorithm has two modes of operation; current mode and voltage mode. It can deal with the unexpected outdoor conditions, which may cause drops in the current, without falsely detecting the battery state of charge.

The FRID EV development work has included studying the driving performance and safety of all types of propulsion systems. Since the FRID EV has propulsion systems which can control the driving and braking torques of the front and rear wheels independently, various outstanding and indispensable functions are produced. Three functions which EVs developed until now could not have are shown here experimentally. The first is the failsafe function under which vehicles continue running without any unexpected sudden stops, even if one of the propulsion systems fails. The second is the function for performing efficient acceleration and deceleration on all roads by suitably distributing the driving or braking torques to the front and rear wheels according to the road surface conditions. The third is the function for ensuring safe running on bad roads, i. e., low μ -roads like frozen roads, by simultaneously controlling slip ratios of the front and rear wheels in consideration of load movement. These are functions are unique to the FRID EV and they have not be realized previously in any gasoline engine-powered car, hybrid car or conventional electric vehicle.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116362788","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}

Main points of this concept include the aging process of the battery, the definition of the SOH, and prediction of the battery's healthy state etc. Aiming at the application mode of the battery packs on hybrid electric vehicles (HEVs), ageing processes of the battery were discussed and several accelerated life test results were listed. Then according to the aging process studies, a power- reflecting SOH definition was proposed. Based on these, a parameter system identification based SOH prediction method was designed.

In this paper, a new forecast algorithm is proposed to predict the position and speed of the rotor with only a low accuracy sensor, which is used instead of a conventional high-resolution position sensor. The new algorithm estimates the rotor position by detecting the rotor speed and acceleration in the previous interrupted cycle of position signal. Simulation and experimental results show that the algorithm can estimate the rotor position successfully and realize the vector control. The system is shown to remain stable and accurate while the motor is uniform, speed up and slow down.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125842275","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}

Randomly-located or unmanaged additions, such as plug-in vehicles, can also have greater impacts at lower penetrations when compared to managed additions such as utility-sponsored storage. The studies also found that potential adverse impacts from such charging loads are highly localized, and once identified are readily managed.

DCTs provide reduced shift shocks and better driver comfort, in addition to higher top speeds and torques. It is therefore an excellent candidate for hybridization. DCTs are also well suited for higher torque diesel engines and high speed gas engines. The easy software tunability characteristics have made them a favorite for a new class of vehicle designs.

Modern Battery Management Systems (BMS) provide a driver for a number of important indications, such as remaining operation time, remaining charge and power. Therefore, BMS is a key element of PEV. However, the performance of the batteries deteriorates during the cycle life, in particular the capacity fades and impedance grows, leading to a decrease in battery power. BMS may decrease these negative effects without creating inconvenience for the end-user. A number of advanced battery charging algorithms were developed in the recent decade.

The context for load control is established by first reviewing system control objectives, including economic dispatch, automatic generation control and spinning reserve. Also, prior work on load control is reviewed. The load control strategy discussed in the paper builds on the concept of a load aggregator. The aggregator acquires data from plug-in electric vehicle loads in its area, and builds a consolidated model that describes overall load availability. When control actions are required, the aggregator broadcasts a common message to all loads, with the response of individual loads dependent upon their interpretation of that message. The interface between the aggregator and the system controller should have a form that allows load control to be integrated seamlessly into the legacy system. The paper discusses the communications infrastructure required to support such a load control scheme.","PeriodicalId":191216,"journal":{"name":"2009 IEEE Vehicle Power and Propulsion Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129015209","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}
