The mass deployment of electric vehicles (EVs) and plug-in hybrid vehicles (PHVs) will also cause significant changes in electricity demand. Therefore, controlling and managing the charging time of EVs/PHVs are imperative for power system operation. We assumed trip patterns of 10 million EVs in the Tokyo power system and analyzed the power system loads, including the charging load of EVs, in some scenarios. We verified quantitatively that charging-time controls are absolutely necessary because the fuel costs for generating power by thermal power plants increase without charging-time controls. Further, we found that load leveling is more effective for multi-car charging management than for single-car charging management.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122438380","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}

Due to many factors, the range is difficult to calculate accurately. This paper introduces an estimation method, in which nine factors are considered, including vehicle current location, remaining battery energy, road network topology, road grade, road link travel speed, acceleration and deceleration, wind speed, status of on-board electric devices and driver's driving style. In the proposed method, to save time and computing resources, range estimation is classified into rough range estimation and precise range estimation according to remaining battery energy. The processing flow is presented in details. Experiment results show that the proposed method can provide accurate driving range estimation and reduce the amount of computing resource, providing convenience to travellers.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123240820","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 paper studies the PEV charging control problem considering the residential distribution transformer life based utilizing a base load prediction algorithm. The objective of the control algorithm is to minimize the transformer loss of life while maintain quality of service. A novel control strategy was developed which calculates a near-optimal total charging load for all available PEVs and then distributes the charging load to available each PEV to maintain good quality of service. Quality of service is measured by the ability of the algorithm to consistently charge available PEVs to near full SOC prior to departure. The simulation results of the proposed smart charging strategy show the effectiveness of the methodology.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332488","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}

Examining discharging/ charging OCV measurement data of a LiFePO4/C cell elucidates these phenomena. A simple equivalent circuit model is newly derived and used in an OCV hysteresis effect-based SOC estimation in the extended Kalman filter (EKF) algorithm. The interval of the relationship between the OCV and SOC is decreased to 5% ΔSOC steps to improve the performance of the algorithm. Additionally, to compensate the model errors caused by the equivalent circuit model and variation in parameters, a measurement noise model and data rejection are implemented because the model accuracy is critical in the EKF algorithm in order to obtain a good estimation. All SOC estimation results of the proposed work satisfy the specification within ±5%.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128385176","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 proposed method locks the active wheels of the vehicle as if they were operating on a common shaft. The locking algorithm is realized by processing the Hall sensor signals of the considered motors and driving them with a single set of “averaged” Hall signals. The proposed Sync-Lock Controller (SLC) is implemented digitally using a programmable integrated circuit microcontroller. First, the Hall signals undergo a layer of filtering to mitigate the errors due to hall sensor misalignment. Then, the locking algorithm is implemented by averaging the filtered Hall sensor signals. The proposed technique locks the motors directly through their corresponding magnetic fields and is shown to achieve better results as compared to a conventional speed control loop. The SLC prototype is implemented in the form of a standalone dongle-circuit that can be easily placed between the original Hall-sensors and the BLDC motor driver.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125622772","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}

Both finite volume Computational Fluid Dynamic (CFD) model by FLUENT and finite element electromagnetic model by JMAG are applied to make the simulation accurate and comprehensive. Average temperature over the stator back, pressure drop between inlet and outlet and average heat transfer coefficient over the cooling duct are evaluated under identical flow rate, velocity and pressure drop for different cooling approaches. In addition, the influences on torque and power performances by the cooling ducts made in the housing or stator back are evaluated by JMAG model. The directly cooled motors show lower temperature rises at the stator back since the direct contact between coolant and stator back can avoid the unnecessary thermal contact resistances between the stator back and housing, meanwhile make the coolant more close to the heat sources, and thus improve the cooling efficiency.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"1957 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125307762","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}

Future smart grid implementations hold the key to transferring information and control parameters between distributed and centralized decision agents. The discussion highlights the opportunity to leverage federal investments in grid renovation and electric vehicle introduction to create system-wide value from improved reliability and reduced fossil fuel consumption. An approach to scaling a previously defined “green signal” methodology for electric vehicles will be detailed across a utility grid balancing region. The research will include a synopsis of the communications opportunities and challenges of coordinating the responses of many resources. The results are expected to show that, with some variation in the charge profiles of individual vehicles, the aggregate set can interface with grid management methods to significantly influence the ability to integrate distributed and centralized renewables to improve environmental quality.","PeriodicalId":134818,"journal":{"name":"2012 IEEE International Electric Vehicle Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114069450","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}
