This report presents the analysis of ultracapacitors for mild/moderate hybrid electric vehicle (HEV) performance. The objectives of this report are to: (1) review the fuel economy improvement trends of today's HEVs with respect to degree of hybridization; (2) perform analysis to see the extent of fuel economy improvement possible with various strategies in mild/moderate HEVs, with no engine downsizing, using either batteries or ultracapacitors; (3) identify energy requirements of various driving events/functions--what matches a limited ucap's energy; and (4) discuss potential roles for high-voltage ultracapacitors in HEVs, if any.
