Available in PDF, EPUB and Kindle. Book excerpt: Argonne National Laboratory has begun an analysis of the energy and air emission impacts of hybrid electric vehicles (HEVs) over the entire energy cycle, including manufacturing, operating, and recycling the vehicles and producing their fuel. Phase 1 evaluates series HEVs using lead acid and nickel metal hydride batteries, operating independent of the electricity grid and connected to it, and compares them to conventional ICE vehicles. With efficient electric components, both grid-dependent and grid-independent vehicles are more efficient than their conventional counterpart, though most of the efficiency advantage is gained in slow, lower power operation (e.g., on the federal urban driving schedule). The grid-independent HEV is not clearly superior if it operates part of each day with grid electricity. Finally, estimates of lead emissions for the lead acid battery-powered HEV are significantly lower than suggested elsewhere.
