Ultracaps Could Boost Hybrid Efficiency
By Kevin Bullis on August 20, 2009
Energy storage devices called ultracapacitors could lower the cost of the battery packs in plug-in hybrid vehicles by hundreds or even thousands of dollars by cutting the size of the packs in half, according to estimates by researchers at Argonne National Laboratory in Argonne, IL. Ultracapacitors could also dramatically improve the efficiency of another class of hybrid vehicle that uses small electric motors, called microhybrids, according to a recent study from the University of California, Davis.
