The advancements in material technology help the industries to enhance the power density as well as the efficiency of an electrical machine to a greater extent. Conductors play a major role in improving the machine's performance. In this paper, the role of conducting materials in high power density electrical machines are discussed. Graphene is an advanced nanomaterial that exhibits excellent conductivities with low mass density. Using graphene coated windings, the weight and volume of the machine can be reduced significantly. In order to understand the prominent features of the nanomaterial based conductors, a case study has been carried out in different electric vehicles such as Toyota Prius (2017), Nissan LEAF and BMW i3. Moreover, a major constraint in high power density machine is the temperature rise, which is discussed at the end.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47599000","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}

Using a hybrid power train (HPT) can reduce fuel consumption in the urban cycle, which is important for commercial vehicles used to deliver goods and passengers within the city, especially when it comes to megacities where traffic is difficult and average speeds are not high. Unfortunately, the cost of cars with a HPT, such as Toyota Prius, Lexus RX 450H, Ford Fusion Hybrid and others, remains quite high and cannot be fully compensated just at the expense of fuel economy.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47205569","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 paper, PCMs are used for thermal management of an electric battery pack. Paraffin with a melting temperature of 58°C, OM35 with melting temperature of 35°C, two PCMs (paraffin and OM 35) were used for the study, as mixtures at two different ratios (50 : 50 and 60 : 40). Computations and experiments were allotted to estimate the heat transfer, solidifying and melting characteristics of the PCM utilised in the Li-ion cell battery module. Since PCM has low thermal conduction, thermal improvement techniques were investigated by inserting the copper plate into the PCM mixtures to boost the thermal conduction. PCM combination 50 : 50 is capable of holding battery running temperature compared to PCM combination 60 : 40. PCM combination 50 : 50 evidences to be ideal and lowered the operating temperature of the battery pack to 47°C.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49081122","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 particular, multi-quadrant capabilities and improved control performances of modern electric drives can be fully exploited to improve vehicle efficiency, stability and overall environmental impact. Conventional, mechanical friction brakes are currently devoted not only to stop the vehicle but also to the actuation of safety related mechatronics systems such as electronic braking distribution (EBD), AntiBlockierSystem (ABS) and electronic stability control/program (ESC/ESP). The result is an over-actuated system of electrical (electric motors) and mechanical actuators (friction brakes), whose mixed, blended application has to be carefully optimised. In this work a simplified approach is proposed in which concepts transferred from previous studies on high speed trains and autonomous vehicles are re-purposed and adapted in an innovative way to electric road vehicles.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/ijehv.2020.106339","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43004836","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 paper, applying pulse width modulation (PWM) technology, IPU converts the high-voltage DC power from power battery into three-phase AC power with adjustable voltage amplitude and frequency through the switching device IGBT to drive the permanent magnet synchronous motor. Due to the large di/dt and du/dt during the IGBT switching process, the spectra of switching voltage and current waveforms have rich high-frequency components, which generate electromagnetic interference through the circuit connection or space radiation, affecting the normal operation of electrical systems inside and around the car. Therefore, this paper analyses the electromagnetic interference mechanism and coupling propagation paths of motor drive system. The test bench of IPU was built, and the EMI characteristics of IPU were analysed based on the measured results. Finally, in order to suppress IPU electromagnetic interference, the corresponding methods are proposed to meet the electromagnetic compatibility requirements of the vehicle.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66764995","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}

For accurate simulations of the reducer gear vibrations, an integrated dynamic model of the transmission is established using professional software MASTA, on which compliance effects of gear pairs, bearings, transmission shafts and gearbox housing are counted for. Numerical analyses are carried out for dynamic responses of the hybrid transmission. Bench tests are also conducted for the present model validation. Computational effort is made to recognise parametrically resonant patterns that cause gear whine in experiment. An optimal tooth modification design is presented for the real multi-mesh gear train. It is shown by test results using the optimised reducer that gear whine responses of the gearboxes are considerably improved.","PeriodicalId":43639,"journal":{"name":"International Journal of Electric and Hybrid Vehicles","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66764983","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}
