AeroVironment (AV) formally announced that it performed a fast charge demonstration of a lithium-ion battery pack for EVs for representatives of the California Air Resources Board (ARB). AeroVironment had earlier described the demonstration in an ARB hearing on the Zero Emission Vehicle program. (Earlier post.)
The 35kWh (kilowatt-hour) battery pack, developed by Altair Nanotechnologies, is designed for use in the Phoenix Motorcar Sport Utility Truck. This battery pack is designed to allow the truck to travel more than 100 miles on a single charge. The test, conducted by engineers at AV’s Monrovia, California Energy Technology Center, was a milestone in battery fast charging, demonstrating the capability of fully charging the pack in less than ten minutes.
AV engineers used a grid-connected AV advanced battery charger rated at 250kW. Prior testing of the Altairnano NanoSafe battery technology by AV demonstrated that such battery packs can sustain several cycles per day of ten minute charging and two hour discharging. Each cycle is equivalent to an electric vehicle traveling for two hours at 60 mph.
