PHEV Modeling
Background
The Advanced Energy Initiative (AEI) announced by the President in the 2006 State of the Union address describes plug-in hybrid electric vehicles (PHEVs) as a way to dramatically increase energy efficiency and utilize spare electric generating capacity. The Plug-in Hybrid Electric Vehicle R&D Plan (2.2Mb pdf) describes the different activities required to achieve these goals.
The U.S. Department of Energy (DOE) will use Argonne's Powertrain Systems Analysis Toolkit (PSAT) to guide its analysis activities, stating that:
"PSAT will be used to design and evaluate a series of PHEVs with various 'primary electric' ranges, considering all-electric and charge-depleting strategies. The objective is to quantify the impact of all-electric range on component performance requirements. The concern is that the peak power requirements for the battery and electric drive are much higher to achieve the same performance in electric and hybrid modes. This impacts the vehicle economics; higher energy and power requirements drive up costs of the battery and electric drive components, which reduces the likelihood or production. The primary outcomes of the vehicle analysis are:
- Potential for fuel consumption reduction of PHEVs as a function of propulsion system configuration, component sizing and control algorithms.
- Component performance goals and requirements."
Argonne's Research
Argonne leads the U.S. DOE vehicle simulation activities for PHEVs, from component requirements to control strategy to fuel efficiency evaluation. Main research areas include:
