Abstract
PHEVs combine today' s hybrid automotive technology with large battery systems
that can be recharged from the electrical grid. With their substantial
batteries, PHEVs can drive short distances before needing to draw upon their
gasoline engines and can therefore achieve significantly greater kilometers per
liter. This report examines how automakers, battery developers, utilities, and
policy makers are approaching the possibilities of PHEVs as well as the
technical challenges that must be overcome to achieve widespread
commercialization.
"PHEVs have great potential in the future evolution of intelligent grids. They
can offer utilities benefits in terms of increased off-peak power sales and the
potential to tap the energy stored in PHEV batteries for ancillary services or
demand response," said Roberta Bigliani, research director, Energy Insights
EMEA. "Their significant market penetration likely remains 10 years away.
Nevertheless, utilities and carmakers should speed-up pilots and begin to
rethink the grid and the requirements for handling distributed sources and
two-way power flows."
