Abstract: The idea of plug-in hybrid electric vehicles is not new. Relatively detailed examinations of plug-in hybrid powertrains relative to hybrid powertrains were recently completed (Graham et al, 2001, 2002; Plotkin et al, 2001). However, the past studies have not examined the ability to replace gasoline use with electricity in plug-in hybrids with relatively moderate electric storage capability, over energy storage values from about 2-7 kWh. These studies have not examined lithium ion battery packs. Further, they have not examined the possibility of using charge depletion in conjunction with continuous engine on capability to make use of electricity to replace gasoline, without ever committing the vehicle to run exclusively electrically. Such vehicles would have an “Electric Range Equivalent” (ERE) capability, in contrast to an All Electric Range (AER) capability.
This study will be focused on presenting ANL’s experiments aimed at determining the energy benefits and petroleum usage displacement of P-HEV considering battery technology and control strategy impact.
