Accordingly, the integration of supercapacitors (SC) in the EV energy management system helps in boosting its performance by distributing the motor load among the two energy sources. This work presents an energy management strategy for a hierarchical hybrid EV energy storage system (hHESS) that relies mainly on SCs to address the EV energy requirements during urban driving cycles with frequent accelerations and decelerations, while restricting the role of the EV battery to recharging the depleted SCs. This decreases the stress that would, otherwise, be imposed on the battery due to frequent variations in the motor's energy requirements. The New York City Cycle (NYCC) is used in this work to model a low-speed urban driving pattern with frequent stops, accelerations and decelerations. Observable improvements in the EV battery performance are noted when compared to utilizing traditional, battery-only operation during urban driving.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132592950","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}

Increasing specific power, going towards electrification and improving efficiency have all to do with power electronics components and rising voltage and temperature, thus electrical and thermal stresses if volume and weight are an issue (as they are indeed). This paper indicated tracks towards facing problems that power electronics supply and higher electrical and thermal stress can cause to insulation system reliability for any electrical asset components in flying and ground aerospace installations. Specifically, manufacturing and performance of a power electronic generator, pulse-width modulated, able to test electrical systems in lab under real voltage waveforms and temperature, is described. Generator parameters, as modulation and carrier frequency, switch slew rate, number of inverter levels, can be adjusted case by case, depending on the solutions used on a specific aerospace electrical asset. The second topic is driving through partial discharge (PD) measurements under such voltage waveforms, with PD pulses that can be easily hidden by switching noise and so fast voltage impulse rise time that frequency-based filtering is not feasible. The time-based partial discharge extraction presented here is innovative, automatic and it could work in a broader analytics contest where partial discharges are separated from noise and the type of source generating them identified. Indeed, identification would be a must, whether insulation system design or diagnostics have to rely upon the absence of partial discharge phenomena or remedies in case they incept due to aging.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122422956","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}

Neodymium Iron Boron (NdFeB) permanent magnets are typically used in permanent magnet synchronous machines (PMSMs) for EV applications for achieving high power, high torque density and high efficiency due to high remanent flux density $(boldsymbol{B}_{boldsymbol{r}})$ and maximum energy product $(boldsymbol{BH}_{boldsymbol{max}})$. Market dominance of NdFeB is hindered significantly due to the supply chain limitations of rare-earth elements which also have the tendency to experience significant price fluctuations. This has triggered substantial efforts in investigating new, alternative magnetic materials containing rare earth free elements. Although ferrite magnets have been explored as alternative choices in the past, ferrites have inferior magnetic properties compared to the emerging MnBi magnets. In this paper, a finite element-based multi-physics design and optimization framework of a SPM machine is conducted evaluating MnBi and NdFeB magnets including electromagnetic performance at high temperatures with thermal and mechanical validation.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116330875","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 generates home-base charging load profiles using real-world activity data for a drayage truck fleet operating in Southern California. As a likely scenario, trucks with a battery capacity of 565 kWh were modeled charging at their home-base (i.e., fleet depot) at two power levels. We then consider constraints of energy needed to complete the next subsequent tour and Time-of-Use (TOU) energy rates. An uncontrolled baseline charging scenario was also modeled for comparison. Results suggest that a decrease of about 21% in energy charging cost can be achieved when comparing the baseline vs. constrained scenarios using a 50 k W power level. A similar decrease in cost was found when modeling a power level of 150 k W. In addition, the percentage of tours completed increased approximately by 10-12%, just by adjusting the charging power level. Finally, the proposed constrained scenarios decreased the number of required chargers by 2–3 on average when compared to their baseline cases.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114727991","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}

Besides other approaches, online parameter identification is suited for real-time observation of the machine condition during operation. Two of the most established online parameter identification algorithms are the recursive least squares and the extended Kalman filter algorithm. In existing approaches the algorithms identify the absolute parameter values. In this paper the used identification models are modified to directly identify the parameter deviation related to the reference values. This results in an additional advantage in identifying operational parameter changes because nonlinear behavior is provided by the respective parameter reference.

Power demand on auxiliary loads continues to expand due to increased computation requirements and load profiles. This requires development of power conversion systems that can manage high-currents efficiently. Construction of high current power conversion systems require multiple power switches (MOSFETs) in parallel, which reduce conduction losses. Efficiency can be further improved by incorporating Kelvin-source connections due to improved decoupling of the gate-source (G-S) and drain-source (D-S) loops in a MOSFET. This paper proposes a method to create a Kelvin-source connection in SMD silicon (Si) MOSFET packages with multiple source terminals. A comparison of switching energies between the conventional and proposed methods to highlight the improvements is performed. A 10–14 V/2.8 kW capable full bridge (FB) synchronous rectifier is constructed for application in a DC-DC converter. Parallel connected HDSOP-16 Si MOSFET packages are used to construct this rectifier with the proposed Kelvin-source and imbalances of the root-mean-square (RMS) current ($I_{RMS}$), turn-on ($I_{on}$) and turn-off ($I_{off}$) currents, resultant power loss profile and effect on the design's thermal gradient are studied.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130451791","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}

To address this issue, PV sources are used to compensate for voltage deviation within the specified range. While voltage regulation in transmission networks depends largely on reactive power, sub-transmission or distribution networks with resistive or mixed (L and R) lines depend on both active and reactive power. Existing control schemes, such as P-Q-V droop and network agonist adaptive PQ method, are uncoordinated and can lead to overloading and stress on the system. There is a need for coordinated control schemes that inject active and reactive power in a controlled manner, which is not sufficiently discussed in the literature. To address this need, a centralized supervisory voltage controller (CSVC) is proposed in this paper to minimize voltage deviations at various buses. The CSVC uses a Wide Area Measurement System (WAMS) to obtain information on bus voltage. Based on the available voltage deviations, the CSVC assigns reference active and reactive power signals to each local controller of the distributed PV source. The proposed CSVC can regulate the voltage of the buses within the required limits during underload and overload conditions. The reference signals allocated by the proposed CSVC are designed in such a way that each PV source supplies active and reactive power in proportion to its rated capacity. This helps reduce the overloading of PV source converters. The converter is controlled intelligently to maintain bus voltages within the specified limit, considering the IEEE standard 1547–2018.","PeriodicalId":234784,"journal":{"name":"2023 IEEE Transportation Electrification Conference & Expo (ITEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114541116","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}
