To meet the power and energy requirements, multiple lithium-ion cells will need to be connected in series and parallel. The number of cells needed will depend on the voltage, capacity, and current limit of the individual cells used. The simplest way of connecting multiple cells in parallel is to tie all of the positive terminals together and all of the negative terminals together, creating a new array of cells that can be treated as a single cell within the battery. In this configuration, a single battery management system (BMS) can be used and though this configuration is simpler and more cost effective, it makes it impossible to monitor the individual cells within each parallel array. Any impedance mismatches among a parallel array of cells introduces the possibility for current imbalances to occur. Significant current imbalance could negatively impact the battery's lifetime as well as its safety. The study performed here aimed at measuring the current imbalance present in a battery that has thirty cells connected in parallel (1S/30P) when it is cycled in a pulsed manner at high discharge rates. The current balance observed across two different rates is being characterized and the possible impact it has on battery performance and lifetime is being evaluated. A novel test bed with individual cell diagnostics has been developed that will be discussed along with the methodology behind the research, and the results collected to date.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129390327","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 objective of this study is to revolutionize electrical insulation in the manufacturing of NGIPS motors for military electric propulsion with game-changing torque density and payload efficiency through the development of nanostructured insulation with significant improvements in both electrical and thermal performance. This paper presents the progress of nanostructured insulation innovation, high field characterization, performance and insulation integrity validation under high voltage, high frequency multi-stresses. The thermal, dielectric and voltage endurance properties of novel nanocomposite insulation based on 2D-nanostructured platelet fillers were investigated. It was demonstrated that nanostructured insulation could offer significant improvement over conventional insulation system in electrical, dielectric, thermal and mechanical properties. A Design of Experiment was employed to study the effects of various 2D fillers and their interplay, and more importantly to identify the optimal nanostructured formulation with high thermal conductivity of >0.8 W/mK, low dielectric constant of less than 5, low dissipation factor of less than 3% at 150°C and high breakdown strength of >1000V/mil. Furthermore, disk samples with optimal formulation from Design of Experiment were fabricated for voltage endurance tests in accordance with IEC 60343 standard for evaluation of their long-term endurance life.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132608842","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 is especially true in order to achieve a high reliability and long lifetime, in conjunction with a reasonable insulation size and weight that is important for electric ship applications. Most of the weak points inside the solid insulation are located in the void or defect inside insulation, especially those near the field crowding area. An example of this is a self-made laminated bus. This paper will show how to model the actual structure and perform the electric field analysis, even with a single void. In order to reduce the stress for the insulation, several useful methods to decrease electric field crowding will be discussed. All these methods will be verified by FEA simulation. Then, a non-destructive partial discharge (PD) method to evaluate insulation will be introduced. The self-made laminated bus PD behavior under the line frequency sinusoidal and DC excitation will be captured. Later, a simple PCB coupon will be tested and its PD behavior under 60Hz sinusoidal and 60Hz unipolar square wave will be shown separately. These will somehow, demonstrate the difference between the insulation aging mechanism, especially under PWM-like excitation. However, deep understanding in how to evaluate and improve the insulation, especially as it applies to power electronics applications, needs to be explored in future work.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116733744","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}
