We estimate a model of electric vehicle (EV) adoption in 427 the largest metropolitan areas 48 contiguous U.S. states. observe all new battery vehicles (BEV) and plug-in (PHEV) registrations by metro area over 2011–2018 period, we investigate whether EVs is statistically related to multiple types air pollution – long-term as measured ambient PM2.5 temporary events presence wildfire smoke plumes...

In order to meet cost targets for hybrid electric (HEV), Plug-in hybrid electric (PHEV), and allelectric vehicles (EV), an improvement in the battery life cycle and safety is essential. One practical approach to improve performance is to use power electronics intensive cell equalizer, in conjunction with on-board energy storage devices. A new technique based on buck-boost topology to equalize a...

In this paper, an energy management method is proposed for a power-split plug-in hybrid electric vehicle (PHEV). Through analyzing the PHEV powertrain, a series of quadratic equations are employed to approximate the vehicle's fuel-rate, using battery current as the input. Pontryagin's Minimum Principle (PMP) is introduced to find the battery current commands by solving the Hamiltonian function....

The Electric Power Research Institute (EPRI) is currently conducting a long-term project to promote the development of grid-connected, plug-in hybrid electric vehicles (PHEVs) for the commercial automotive market. This collaborative effort with partners in electric utilities, the automotive industry and government includes subtasks of specification development, prototype vehicle design and cons...

In order to reduce greenhouse gas emissions in the United States by an order of magnitude, a portfolio of mitigation strategies is needed. Currently, many utilities pursue energy efficiency programs. We study a case where utilities could choose whether to allocate their energy efficiency budget to either end-use efficiency or vehicle electrification as a means to reduce CO2 emissions. We build ...

Abstract: This paper studies the power management of a plug-in hybrid electric vehicle (PHEV) using quadratic programming. The proposed quadratic programming can obtain the global optimal solution of the power distribution between battery/motor and engine while maintaining vehicle performance. Computation time can be significantly saved compared with dynamic programming. Therefore, it can be us...

Current research on Deep ReinforcementLearning (DRL) for automated on-ramp merging neglects vehicle powertrain and dynamics. This work considers a power-split Plug-In Hybrid Electric Vehicle (PHEV), the 2015 Toyota Prius Plug-In, using DRL. The control PHEV energy management are co-optimized such that DRL policy directly outputs power split between engine electric motor. testing results show ca...

In order to make the sustainable development of transport system, China has taken actions toward electrification transition vehicles. However, whether electric vehicles (EVs) are more environmentally friendly than conventional internal combustion engine (ICEVs) in is still not clear due a lack complete and consistent environmental impact comparison This study takes vehicle models from BYD Qin P...
