This paper investigates the charge-discharge characteristic for lithium ion batteries developed focusing on cathode materials of LiNiCoMnO2 (NCM) – layered structured material with lithium anode. It also discusses the characteristic features of charge-discharge profile, optimized charge-end voltage as well as discharged limit voltage with a constant current C-rate with 0.1C, 0.3C and 0.5C. The coin cells were fabricated in a glove box full of argon gas using those cathode and anode with separator and organic electrolyte (1M LiPF6, EC: DEC 1:1). The performance of charge-discharge test was conducted with NEWARE tester equipment BTS 3000. This includes obtaining experimental data charge- discharge and power capacity to improve the performance of battery. Thus it is reported that charge-discharge characteristic of LNCM material is important to be analysed for LIBs. The parameter attained is vital and necessary enhancement work for the resolution of optimization BMS simulation. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129905449","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}

What is more important is that this technical problem may find a more direct solution as opposed to human behavioural issues. This study aims to discuss common vehicle defects that probably contribute to road crashes by using Periodical Technical Inspection (PTI) database as the basis. Data was analysed to determine common failures of private passenger vehicles based on selected inspections and vehicle types. At this stage, only voluntary and routine inspections were scrutinized. In addition, this study is able to predict the probability of a vehicle failure by using information from the database. From such an analysis, it was found that the two most common private passenger vehicle defects were worn out tire (or lack of tread) and structural integrity. It was also found that vehicles sent for voluntary inspection have a higher probability of failure compared to those sent for routine inspection. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"635 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124561908","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}

A digital camera and a hands-free camera harness were used to hold the camera at the chest level to record the riding scenarios. Fifteen courier riders in the Klang Valley, Malaysia participated in the study. The final analysis reveals that a courier rider encounters 30 hazardous riding events and 5 near misses on average for each hour of delivery trips. Two-thirds of all hazardous riding events were instigated by road users, including the participants themselves. Interestingly, the participants' own riding behaviours contributed to almost a third (29%) of the total near misses. Obstruction of view was found to increase the odds of causing a near miss by 4.61 times compared to hazards related to driving behaviours of other motorists. Further, incidents related to lane changing or overtaking manoeuvres were found to have 7.81 times higher odds of causing a near miss compared to incidents related to braking or sudden stopping. The classification of hazards and risk assessment presented in this study should be seriously considered for better operation management and defensive driving training. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131389465","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, localization becomes poor as a vehicle enters GPS-denied areas due to multi path errors. Autonomous vehicle, in addition, needs to be localized from time to time and be guided on the right path along its destination. The purpose of this study is to overcome the problem of adopting an alternative method by using the vehicle’s Wheel Speed Sensor (WSS) for localization. WSS as an auxiliary sensor is attached to the vehicle’s wheel to track its position upon considering its travelling speed in a period of time. This is done in such a way that the existence of obscured portion along the guideway will be neglected. The data obtained from WSS are combined with yaw rate from an Inertial Measurement Unit (IMU) through Kinematic Modelling algorithm and then be converted to get the local position coordinates. In order to analyse whether the yaw rate produced by IMU is acceptable or not, comparison with simulation is needed. A Bicycle Model is used to generate simulated yaw rate from the steering angle of the vehicle and Kalman Filter estimates the simulated yaw rate to be close with the raw yaw rate. Therefore, this will clarify that the yaw rate obtained from IMU is acceptable and that true localization path is generated. \u0000 \u0000 \u0000","PeriodicalId":286928,"journal":{"name":"Journal of the Society of Automotive Engineers Malaysia","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117237657","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}
