The magnetic density depends on the level of magnetic source quality and the magnetic source position. Some parameters to determine permanent magnet coordinate are its distance to the rotating center or to the conductor. This paper investigated the impacts of position parameters in single disk axial ECB on braking torque. The study was conducted using FEM modeling that had been validated by experiment. The results showed that distant permanent magnet position from the rotating center produced more braking torque due to larger hand force. The maximum value of the magnetic source coordinate was found at 50 mm from the rotation center. Braking torque decreased as the air gap increased. Equal braking torque was also found at the distant radius permanent magnet in all of air gap variations. This happened because of flux magnetic effect. Thus, with proper parameter positions, a design of single disk axial eddy current brake can achieve optimum performance with less cost.","PeriodicalId":6659,"journal":{"name":"2018 5th International Conference on Electric Vehicular Technology (ICEVT)","volume":"3 1","pages":"132-135"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90260627","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}

In this research, two motors are used to move 2-Independent-Wheel-Drive of an electric urban bus. In the connection between the two motors, the control system is required to align the performance of both motors to keep the bus stable. This study used the fuzzy logic control in Matlab/Simulink to drive the dynamics of the vehicle modeled in TruckSim. Through calculation, it was found that the maximum lateral speed of the vehicle had the characteristic speed of 150.36 km/h, with wheel angle conditions and slip angle that occurs are 10 deg and 5 deg. However, the speed at which the simulation is used is the maximum speed of the bus with a full charge of 70 km/h. After the simulation, the difference between the yaw rate is ideal, and the actual yaw rate was compared with the yaw rate range derived from the calculation. In the fuzzy logic control, the difference must be less than the yaw rate range. Simulation results showed that the control system was able to align the 2-independent motors by considering the yaw rate; thus the method can improve the dynamic stability of the bus.","PeriodicalId":6659,"journal":{"name":"2018 5th International Conference on Electric Vehicular Technology (ICEVT)","volume":"52 1","pages":"36-40"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83702080","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}

Particularly, Zn-air battery offers high specific energy and low production cost. We present a method to improve the cycle life of the rechargeable Zn-air battery by introducing additives into the alkaline electrolyte. Thiourea and polyethylenimine are chosen as the additive to suppress the growth of Zn dendrite during the charging process. Combination of thiourea and polyethylenimine as electrolyte additives is shown to produce smooth and compact Zn deposits. As a result, charging profile and cycling stability of rechargeable Zn-air battery with thiourea and polyethylenimine as electrolyte additives are improved as compared to the Zn-air battery without any electrolyte additives. The battery with electrolyte additives shows a stable performance for up to 250 discharge/charge cycles, which is higher than the battery without any electrolyte additives (187 cycles). This study illustrates a method to design a robust electrolyte system for a long cycle life of rechargeable Zn-air battery.","PeriodicalId":6659,"journal":{"name":"2018 5th International Conference on Electric Vehicular Technology (ICEVT)","volume":"11 1","pages":"128-131"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89548095","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 type of solar cell uses a 100-watt solar cell type silicon mounted on a portable basis and parallel connected. The position of solar cells are installed in three different areas in different around Semarang city. The altitude of each region is 0 -7.5 m, 350 - 450 m and 600 - 800 m above sea level. Battery charging duration of three altitudes has different time range. These condition are caused by the quality of light intensity that reaches the solar cell. At higher altitude has a relatively fast charging rate compared to lower positions due to a higher intensity. This information is used to determine the required solar cell panels on the vehicle to charge the vehicle battery and battery charging time.","PeriodicalId":6659,"journal":{"name":"2018 5th International Conference on Electric Vehicular Technology (ICEVT)","volume":"43 1","pages":"100-102"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87080262","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}
