"Test methodology for electric vehicles"

As one phase of the work being performed by the Jet Propulsion Laboratory (JPL) for the Department of Energy (DOE), tests are being conducted on electric and electric hybrid vehicles, During the past year this testing was primarily involved in determining the performance improvements possible through retrofitting electric vehicles (EVs) with improved batteries, Testing consisted of a baseline series which characterized these vehicles with their "as received" lead-acid batteries and then an additional series of tests which characterized the same vehicles with experimental nickel-iron (Ni-Fe) and nickel zinc (Ni-Zn) batteries.
