This paper presents information from an ongoing benchmarking project being conducted at Oak Ridge National Laboratory (ORNL) and funded by the Department of Energy (DOE). Beginning with the 2004 Toyota Prius, ORNL has benchmarked components from many on-the-road EVs, HEVs, and PHEVs. Detailed design, packaging, and operational assessments are presented on power electronic converters (such as inverters, buck converters, and bi-directional boost converters), electric motors (such as the primary drive motor and generator), and other associated components. Packaging assessments reveal mass, volume, and material compositions, and empirical evaluations provide efficiency, performance, and operational data throughout the entire operation range of each component.

Electrification of performance vehicles brings several challenges such as the necessity of high-power sources, which can satisfy the power requirements during acceleration and efficiently retrieve energy during deceleration, without performance and lifecycle deterioration of such sources. In addition, the limited space under the hood for these vehicles exterminates the possibility of utilizing large volume high-power propulsion machines. This manuscript proposes an efficient wavelet-transform based energy/power decoupling strategy implemented on a unique power-split gear (PSG) based powertrain deploying two propulsion machines with a hybrid battery/ultra-capacitor (UC) energy storage system (ESS) to overcome the limitations associated with electrified performance vehicles. The proposed control and management strategy guarantees that battery provides the base, transient-free power while transients are compensated by ultra-capacitor. With the proposed hybrid ESS and energy/power decoupling strategy, power density of the ESS can be increased, vehicle performance can be improved and battery lifetime can be prolonged.

Buffer circuits are widely used in high-power inverters' gate drives to get enough driving current for power modules or power transistors in parallel. In this paper, designs of buffer circuits to boost the output current for a gate driver IC are investigated. Different buffer topologies are reviewed and their individual advantages and disadvantages analyzed. Based on the analysis, three topologies, specifically the BJT emitter follower, the two NFETs totem pole, and the CMOS buffer, are chosen for further study. Optimizations are performed on these three buffers by taking the driving capability, switching speed, circuit complexity, and cost into account. After that, a test setup is built, and the driving performance of the buffers is characterized and then compared experimentally with a commercial buffer IC with a rated current of 30 A. All three proposed buffers show better performance and lower cost, which verifies the feasibility and effectiveness of the proposed optimization methods. Double pulse test results indicate that the addition of a buffer stage makes the switching performance less sensitive to the load and can achieve significant performance improvement when large or parallel power switches are to be driven.

Experts theorized that a Brushless Wound-rotor [Synchronous] Doubly-fed Electric Machine System (BWRSDF), which can symmetrically motor or generate with variable speed, provides higher efficiency, higher power density, higher torque density, and lower cost than any other electric machine system, including the permanent magnet electric machine system, but only with the discovery of a practical brushless real time control solution for its known issues of instability and the multiphase slip-ring assembly that continually eludes state-of-art control methods, such as Field Oriented Control (FOC). Comprising a dual-ported transformer circuit topology with the attractive characteristics common to the advanced induction electric machine system, such as versatility, robustness, field weakening, practically unconstrained torque and power rating, simplicity, and low cost, etc., but with higher efficiency and torque than the permanent magnet electric machine system, the fully electromagnetic core of the BWRSDF uses readily available technology and materials without the market volatility, safety and reliability issues of rare-earth permanent magnets.

This paper presents a extented Kalman filter based on a dynamic model of a commercial lithium ion battery pack in automotive applications, and experimental data are collected using the Noao. This vehicle is an electric track with range extender, which has been developed and produced by the association Pôle de Performance de Nevers Magny-Cours (PPNMC). This model has been developed with MATLAB/Simulink to investigate the output characteristics of lithium-ion batteries. It incorporates I-V performance of the battery, battery capacity fading, temperature effect on battery performance, and the battery temperature rise. This estimation technique is used in order to estimate some parameters, which cannot be measured directly by physical sensors such as SOC and SOH and to compensate for uncertainties in the model parameters and the measurements. The proposed model is validated by comparing simulation results with experimental data collected through battery testbed of Noao vehicle.
