“…To maintain an acceptable battery voltage (around 200 V), the algorithm will change the battery capacity rather than the number of cells to meet the AER requirements. To do so, a scaling algorithm [8] was developed to properly design the battery for each specific application. Finally, the PHEV will operate in electric-only mode at a higher vehicle speed than will regular hybrids.…”

“…Previous studies that focused on the impact of other standard cycles [6] or powertrain configurations [7] demonstrated the need to further evaluate driving behaviors. Argonne has been working in collaboration with the U.S. Environmental Protection Agency (EPA), which has been interested in real-world fuel economy in the past few years [8]. This paper addresses the impact of real world drive cycles on PHEV fuel efficiency and cost.…”

For the past couple of years, Plug-in Hybrid Electric Vehicles (PHEVs) demonstrated their ability to significantly reduce petroleum consumptions. However, more than any other vehicle powertrain, their benefits are dependent on the driving cycles from both an aggressiveness and distance point of view. In this paper, two powertrain configurations will be defined. A power split configuration will be used for low battery energy and a series configuration for high battery energy. For each vehicle we will evaluate several control strategies, including electrical dominant and blended, on real world drive cycles. A conventional vehicle will be defined to use as a baseline. The trade-off between fuel displacement and cost will be evaluated for each option.

“…Overall, ten studies have been conducted and the daily commute driving patterns along with the ESS run-time charge-discharge current profiles were recorded with second-scale time resolution. Our evaluations also leverage the large-scale kansas city user driving studies, which collected user daily commute driving behavior with second-scale resolution [18]. Using the Kansas city driving profile as input, we use PSAT PHEV vehicle model [10] to estimate second-scale ESS charge-discharge profile.…”

Energy consumption and the associated environmental impact are a pressing challenge faced by the transportation sector. Emerging electric-drive vehicles have shown promises for substantial reductions in petroleum use and vehicle emissions. Their success, however, has been hindered by the limitations of energy storage technologies. Existing in-vehicle Lithium-ion battery systems are bulky, expensive, and unreliable. Energy storage system (ESS) design and optimization is essential for emerging transportation electrification.This paper presents an integrated ESS modeling, design and optimization framework targeting emerging electric-drive vehicles. Based on an ESS modeling solution that considers major run-time and long-term battery effects, the proposed framework unifies design-time optimization and run-time control. It conducts statistical optimization for ESS cost and lifetime, which jointly considers the variances of ESS due to manufacture tolerance and heterogeneous driver-specific run-time use. It optimizes ESS design by incorporating complementary energy storage technologies, e.g., Lithium-ion batteries and ultracapacitors. Using physical measurements of battery manufacture variation and real-world user driving profiles, our experimental study has demonstrated that the proposed framework can effectively explore the statistical design space, and produce cost-efficient ESS solutions with statistical system lifetime guarantee.

Plug-in hybrid electric vehicles (PHEVs) have the ability to significantly reduce petroleum consumption. Argonne National Laboratory (Argonne), working with the FreedomCAR and Fuels Partnership, helped define the battery requirements for PHEVs.Previous studies demonstrated the impact of the vehicle's characteristics, such as its class, mass, or electrical accessories, on the requirements. However, questions on the impact of drive cycles remain outstanding. In this paper, we evaluate the consequences of sizing the electrical machine and the battery to follow standard drive cycles, such as the urban dynamometer driving schedule (UDDS), as well as real-world drive cycles in electric vehicle (EV) mode. The requirements are defined for several driving conditions (e.g., urban, highway) and types of driving behavior (e.g., smooth, aggressive).
